When it comes to the mobile app heavyweights, few can beat WhatsApp. It’s estimated that around 3 billion people now use the cross-platform messaging tool at least once a month. And it’s important to remember there are only 8 billion or so people on the planet, so there are no signs of its popularity waning anytime soon.
Beyond being a hugely successful app, it’s also packed with features. You can use it to chat, make voice and video calls, share files, broadcast your location, and more. Even if you’ve used WhatsApp for years, you might not have discovered everything it’s capable of—which is where these tips come in.
1. Set a timer for messages to disappear
You don’t necessarily want everything you say on WhatsApp to be remembered forever, and the app includes a timer feature that will automatically expunge messages in a chat 24 hours, 7 days, or 90 days after they’re read, unless you specifically keep them. This is set on a chat-by-chat basis, and affects everyone in a conversation.
To change the setting for one of your chats, tap the contact or group name at the top of the screen, then pick Disappearing messages to select your time limit. This is applied until you turn it off or select a different period, but doesn’t affect the conversation history.
2. Lock away your most sensitive chats
Put certain chats behind a lock. David Nield
Another way of protecting sensitive information in chats is to add an extra lock to specific conversations. Even if someone should gain access to your phone and your apps, they won’t be able to see your locked chats.
From inside a conversation, tap the contact or group name at the top, then pick Chat lock (Android) or Lock chat (iOS). You can then use a specific PIN code to block access to the conversation, or use the same biometric scan technology (such as Face ID) that already protects your phone at the lock screen.
3. Edit a message after sending it
Have you noticed you can edit messages after sending them? It’s handy for those typos you only spot after dispatching a message—long-press on whatever you just sent, then tap the three dots and Edit (Android), or just Edit on the pop-up menu (iOS). Modified messages have an ‘Edited’ label visible to everyone in the chat, but they won’t be able to see what the original message said.
4. Stop specific contacts from seeing when you’re active
Take control of who sees your activity on WhatsApp. David Niel
WhatsApp can tell your contacts whether you’re currently using the app and when you were “last seen,” but this might not be information you want to share with everyone. As well as disabling the feature entirely, you can also turn it off for specific contacts.
Open the You tab, then tap Privacy > Last seen and online, then select My contacts except … under the Who can see my last seen heading. You can then pick the contacts you don’t want to give this information to, and set the Who can see when I’m online option to match the same list.
5. Pin important messages you need to refer to or remember
Important details can quickly get lost in WhatsApp conversations, especially in busy group chats. But there is a way to pin specific messages to the top of the chat so they’re easy to get back to—someone’s address or the start time of an event, for example.
To pin a message on Android, long-press on it, then tap the three dots (top right) and Pin. On iOS, long-press a message and choose More > Pin. You can have up to three pinned messages per conversation, and select from three options for how long they’re pinned for: 24 hours, 7 days, or 30 days.
6. Give contacts their own notification sound
Your contacts can have their own alert sounds. David Nield
WhatsApp lets you assign specific notification sounds to specific contacts, which means you know who’s calling or messaging without picking up your phone. It gives you a better idea of whether something needs attention right away or can be safely ignored for a while.
Tap the group or contact name at the top of a chat, then pick Notifications and Notification tone or Ringtone to make changes. You can also select Vibrate to customize vibrations for each chat, though there are only four options here.
The option to mute the conversation is on the same screen—you can set mute separately for calls and messages.
7. Message yourself with notes and reminders
Not all messaging apps let you have a conversation with yourself, but WhatsApp does. This might seem like a rather pointless (and lonely) way of using the messaging app, but it can be really useful for jotting down things you need to remember on the go, leaving yourself voice notes of ideas and thoughts, and so on.
From the main conversation list, go to start a new chat, then search for “you” as the contact (or just enter your own username or phone number).
In my eyes, the best gift is a practical one. It’s useful and won’t rot in the back of someone’s closet for years; they’ll think of you whenever they use it; and you get major brownie points for introducing a magical, miracle product into their life. And what’s better than being known as someone who reliably gifts reliable products? I may still get made fun of by family for my history of wanting practical gifts (including lead refills for my mechanical pencil), but the gifts I treasure most often get the most use in my home. These are some of the best practical gear you can give to friends and family members who value utilitarianism over flash and fluff.
The OLIGHT Baton4 Pro rechargeable flashlight is a $63 flashlight that’s well worth the cost. They’ll never need another flashlight, and they’ll struggle to find one as bright and powerful as this.

Dual switches—a side switch and tail switch—allow for one-handed mode selection (choose from high, turbo, and momentary on). Use it hands-free with an included L stand that sticks to metal surfaces, and know it will stay cool and comfortable in hand, even in Turbo mode. Charge it with the included magnetic charger, or unscrew the tailcap to reveal a USB-C port for universal charging anywhere. Your next power outage, camping trip, and attic exploration mission will thank you for this gift.

Best aromatherapy with attitude: Hand-crafted candles by FRET12

I’ve sung the praises of this $98 Levoit Core300-P air purifier for years. It’s one of our best budget air purifiers, and there are currently two of them in my home: one in the primary bedroom and another in the living room. The replaceable filters aren’t prohibitively expensive, and they’re whisper-quiet at their lowest speeds. I’ve tested many air purifiers, and this one easily beats its more expensive competitors. My asthmatic cat loves this air purifier, my fiancé, who hasn’t gotten sick in years, loves it, and I love it. I’d buy it for all my friends if I could.
Best dehumidifier: Midea Cube 20 Pint Dehumidifier

Best humidifier: Carepod One Stainless Steel Humidifier for Large Room
Carepod One Stainless Steel Humidifier for Large Room $279
Other humidifiers quickly get gross and grody. The Carepod One is a splurge at $279, but this high-end humidifier stays mold-free thanks to a sterilizable, dishwasher-safe stainless steel basin. It has only three parts to clean: the white wand, stainless steel water tank, and stainless steel inner lid. The humidifier runs for up to 30 hours and includes a built-in timer for hassle-free use. It’s Restriction of Hazardous Substances-certified, meaning it’s free of hazardous substances like lead and mercury.
Best handheld vacuum: Shark Cyclone PET Handheld Vacuum
Sometimes, a mess isn’t messy enough to warrant breaking out the big, heavy vacuum, and there is no other pleasure like having a tool for a very specific task. This $80 handheld vacuum from Shark is excellent for cleaning pet hair off couches or collecting the crust from your car. An extra-large dust cup means you can clean all these small messes in one go or have extra room for pet hair when the couch gets particularly fuzzy.
Regardless of water bottle allegiance, the $20 Kuppy Silicone Water Bottle Drying Rack helps reusable bottles of all sizes, wine glasses, and even silicone snack bags dry thoroughly to prevent odor from trapped water.

Best water flosser: Waterpik Aquarius Countertop Water Flosser
A water flosser is the bedrock of a well-rounded oral care routine. The Waterpik Aquarius Countertop Water Flosser is a $100 countertop water flosser that’s more like a power washer for mouths. Choose from 10 settings for extra pearly whites, including a massage mode that helps stimulate gums. Although it’s not a replacement for floss, it’s excellent for getting the job done after a late night. I personally use mine after flossing and add a bit of mouthwash to the reservoir to get fluoride where my teeth need it most.
The Nori Press Travel Steam Iron is a $120 handheld iron that resembles a giant hair straightener.

The TUSHY Classic 3.0 Bidet is a $124 starter bidet that helps your gift recipient feel cleaner than using toilet paper alone.

Best cordless vacuum: Shark PowerPro Flex Reveal Plus Cordless Vacuum

And this $6.50 pack of uniball Jetstream pens is a favorite thanks to its smooth, opaque, quick-drying ink that’s water- and fade-resistant.

Best notebook: LEUCHTTURM1917 A5 (Medium) Notebook
My $26 LEUCHTTURM1917 A5 notebook holds my journal ramblings, my to-do lists, and random neurotic notes I need to get out of my head and onto a page.

I personally go for a hardcover notebook with ruled paper, but LEUCHTTURM1917 also sells softcover journals in every color of the rainbow, with square grid ruling, dotted ruling, or blank pages.
The Ember Mug 3 is the latest generation of the popular smart mug that can keep hot drinks at a precise temperature all day long. Each 14 oz mug includes a sliding lid that extends battery life up to three hours on a single charge (it’s 80 minutes without the lid).

This $50 OtterBox Symmetry Series Case has protected my iPhone 13 for years: the only blemish is a dent in the aluminum bumper from when I took it out of its case and immediately dropped it on my concrete porch. I’ve learned my lesson and never forgo a phone case. The OtterBox Symmetry Series Case is sleek without being too flimsy and protects without bulk. It’s on my repurchase list and should be on yours, too, especially if you’re looking at one of the new iPhone 18s.
Best noise-canceling headphones: Bose QuietComfort Headphones (2nd Gen)
These newly refreshed noise-canceling headphones from Bose are essential for quiet commutes and tuning out the airport chaos while traveling. Bose makes some of our favorite noise-canceling headphones and earbuds thanks to thoughtful design and helpful tech in each pair.

This practical gift is also personal. Every pair of these $249 orthotics from Stride is custom-made from a 3D scan of someone’s foot and a gait video with just their smartphone required, no doctor’s visit necessary. Take a short quiz about pain areas, activity levels, goals, and shoe preferences; provide the digital data; and podiatrists in Germany customize the orthotics and print them on durable TPU (personalized for the recipient) before they arrive at your doorstep in just 10 to 15 days. And they go well beyond arch support. It’s hard to convey the initially odd and then quickly invigorating sensation of an insole that considers each unique contour of the ball of your foot, but we guarantee your achiest friend or family member will appreciate a custom gift that addresses a big pain point, literally.
Best gloves for cyclists and beyond: Hestra CZone Bike Mistral – 5 finger
I hate when gloves hinder my range of movement. These $85 bike gloves from Hestra have a flexible but durable outer fabric and stretchy polyester on the palm.

The nonconductive (Electrical Hazard Certified) outsole is oil- and slip-resistant and is comfortable and durable even after climbing on ladders or standing on unforgiving surfaces like wood, tile, or concrete. Even better, the boots are Danner Recraftable, meaning they are eligible for part replacements, leather care, and restitching (paid services), so you are investing in someone’s ongoing comfort. If your gift recipient is good with laces, the Bull Run Moc Toe is another top choice for both looks and stability.
Best post-workout recovery shoes for athletes: Nike x Hyperice Nike Air Zoom Hyperslide

If an electric guitar and a pedalboard are part of the gear setup, consider adding a tuner pedal like the TC Electronic POLYTUNE 3.
Best durable down jacket: Stio Hometown Down Jacket
After many frigid Pittsburgh winters, I’ve learned that investing in a down jacket always pays off. I’m a fan of Stio’s $449 Colter Down Jacket, but the Hometown style is an even more budget-friendly down jacket. A recycled nylon ripstop outer with a PFAS-free DWR shields from the elements. It’s insulated with HyperDRY water-repellent goose down that offers 800-fill warmth even in wet snow. Other helpful features include pockets for hand warmers and valuable tech, and low-profile cord locks for a customized fit. We also think this limited-edition anniversary denim print shown above is just darling.
On October 16, the National Park Service (NPS)announced the latest additions to a growing list of designated World War II Heritage Cities. The park service began the program in 2020, as a way to honor local ties to history. Officials have since celebrated locations across 46 states and two territories, but there are many more places worthy of distinction.
The10 new cities and counties announced today span Alaska all the way to the U.S. Virgin Islands.
“These designations highlight the enduring legacy of service, sacrifice, innovation, and industrial achievement…and continue to shape our national story,” NPS Jessica Bowron said in a statement.
According to Bowron, this year’s selections include hubs for military manufacturing, training facilities, and logistical centers integral to Allied campaigns. In Aurora, Colorado, Fitzsimons General Hospital cared for wounded returning service members, while the city of Pendleton, Oregon, featured an airfield that trained B-25 crews that later participated in the Doolittle Raid. Meanwhile, South Charleston, West Virginia’s Naval Ordinance Plant supplied invaluable inventories and was largely staffed by local women and Black workers.
A full list of the latest entrants can be found below:
An extensive new analysis further confirms the oldest known human footprints in North America date back to the last ice age (about 23,500–21,700 years). To pinpoint their origins, researchers at the University of Arizona relied on cutting-edge methods at the United States Geological Survey (USGS) Radiocarbon Laboratory to examine hundreds of thousands of prehistoric pollen grains extracted from the tracks. According to researchers writing this week in the journal Science Advances, the team can even describe some of the dramatic environmental fluctuations experienced by these prehistoric humans within a single generation.
New Mexico’s White Sands National Park contains more than stunning vistas and desert dunes. It’s also home to one of the most controversial (and consequential) prehistoric discoveries of the last century. In 2006, archaeologists located footprints inside a dry lakebed that they later determined to be the earliest evidence of humans in North America. But there was a problem. Until then, researchers largely agreed that the first humans migrated into the continent about 16,000–12,000 years ago via Beringia, the subcontinent once connecting Alaska to Russia.
However, the White Sands footprints were estimated to be around 23,000 years old. That implied a sustained human presence on the continent at least seven millennia earlier than expected. Various archeological camps continued debating the true age of the White Sands footprints for years, while others cited similar—and sometimes older— sites in both North and South America. Meanwhile, the dry lakebed’s rarely seen geological conditions allowed researchers like University of Arizona geoscientist Jessica Tierney to learn more than each footprint’s age.
“The White Sands sediments are unique in that they allow us to reconstruct environmental conditions during the last ice age at a very high temporal resolution, so that we can see fluctuations that were relevant for the humans present at that time,” Tierney said.
Combining geochemical sediment signatures with the fossilized pollen, researchers accurately determined ancient regional details such as plant distribution, precipitation, temperature, and aridity. They soon learned that the humans who made the White Sands footprints would have experienced incredibly dramatic environmental shifts within their own lifetimes. Within only a few decades, the surrounding conifer forests transformed into plains covered with oak and sage. Lake Oterio, a giant body of water that once covered New Mexico’s national park, fluctuated in size for about 1,500 years until it receded completely. Although these shifts were large, they actually closely followed similar global climate changes at the time.
“And throughout that whole sequence, people were walking there, leaving their tracks alongside those of mammoths, giant sloths and dire wolves,” added Tierney.
The agents got in through credentials and connection settings left exposed in app configurations, public code repositories, and overly permissive cloud roles.
According to Elorian's evaluations, Glimpse outperforms even GPT-6 Astra on scientific chart reasoning and short-form video captioning, with competitive results on other visual reasoning tasks.
Tressfecta builds products for textured hair. Its first project is a tool called Plait Pilot that helps braiders with the initial process of separating hair from packs before braiding begins.
Nathan Fielder's documentary about disgraced Theranos CEO Elizabeth Holmes has created a constellation of colliding personas that interrogate the very nature of authenticity.
Your eyes really can betray your thoughts, but don’t get too self-conscious about it. Researchers in Japan believe that the subtle signs our eyeballs make are more useful to neuroscientists than the interrogation room. Based on their findings recently published in the journal iScience, examining the difference physiological responses from “inner” versus “overt” speech may help us better understand everything from linguistic development in children to the efficacy of silent pep talks.
To learn more, a team at the University of Tsukuba in Honshu enlisted dozens of volunteers for a series of simple counting exercises. After observing the participants at rest while thinking about nothing in particular for a control, researchers then asked them to count sequentially (1, 2, 3…), in number-subject combinations (one dog, two dogs…), and in specific intervals (1, 3, 5…). They also completed each task both silently and aloud. In each phase, the team carefully monitored their pupil dilation.
The results were subtle, but striking. Participants’ pupils dilated during each overt speech task, but this same muscle movement depended across each inner speech directive. Pupils constricted while volunteers silently counted sequentially, dilated for interval counting, and didn’t change at all for number-subject counting. But regardless of the inner speech task, pupil size changes were always smaller than they were during overt speech.
“The results of the present study do not support the initial assumption that inner and overt speech produce equivalent pupillary responses,” the team summarized. “Across the three experiments, overt speech consistently elicited pupil dilation, whereas inner speech did not.”
This collective data indicates that our inner speech isn’t simply the nonverbal counterpart to talking aloud. Instead, it’s a form of communication that appears to correspond to lower levels of brain arousal. If true, measuring pupil dilation may become a valuable tool when attempting to assess internal language and thinking. This could be particularly useful for studying language development in young children and infants who can’t properly describe their experiences to adults yet.
Tough times can fuel innovation, and battle-hardened Ukraine has demonstrated that fact of life more than most places in recent years. Since Russia’s invasion in February 2022, the country has utilized drones and robotics in ways not before seen in large-scale warfare. More recently, Ukraine has introduced a variety of remotely controlled ground vehicles tasked with entering contested territory and resupplying areas or even evacuating wounded troops. But while those wheeled robots help keep soldiers off the front lines, they are also vulnerable. Their air-filled tires are particularly vulnerable, since they can be shot at or break when rolling over barbed wire, shrapnel or even rugged debris. To solve that issue, engineers from a pair of Ukrainian companies developed a new type of 3D-printable tire that doesn’t require any air at all. And it’s already being deployed on front lines.
The airless wheel is the result of a collaboration between two Print&Live UA, and iSCALE 3D. Their design is proposed to be built for Uncrewed Ground Vehicles (UGV) that come in various shapes and sizes depending on their task. Instead of a rubber casing filled with pressurized air, these new wheels are 3D printed around a lightweight internal lattice made from durable elastomers and composite polymers. The lattice flexes and springs back over rough terrain, essentially doing the cushioning work that air pressure does in conventional tires, but without the risk of a sudden debilitating puncture.
The tires also feature a rounded tread and enclosed sidewalls which are meant to keep mud, stones and ice from packing in. According to Print&Live UA and iSCALE 3D, the result is a wheel set far lighter than Western airless alternatives and that keeps working even after taking some damage. Fewer blown out tires, they say, could mean more lives saved.
“The most important mission of a UGV is not spectacular—it is bringing a wounded person back, or water, medicine and supplies forward,” the companies write on their websites. “Every immobilized vehicle puts people at risk. That is the real purpose of this development.”
“One puncture and the mission ends where the machine stops,” they add.

No tire factory? No problem
In addition to the airless design, the 3D printing process makes the new wheels more adaptable. Each set can be tinkered with and adjusted to best suit the type of vehicle they will be equipped on, as well as for the specific mission type they might engage in. Stiffness, shock absorption, and overall geometry can all be tweaked on a computer. The process requires large, industrial-scale printers most hobbyists won’t have in their garage, but it’s still a much smaller, nimbler approach than an entire factory built to roll out one specific product.
“Because the geometry is digital, stiffness and damping are programmed for each UGV type and payload, and a design upgrade is nothing more than a new file,” the companies write.
The engineers also designed these wheels with the chaos of a battlefield in mind. Each two-piece rim set lets soldiers swap out a damaged tire without the tire-changing machines or presses a conventional repair would need. That flexibility means soldiers can repair or swap tires with simple hand tools in battlefield areas where full workshops aren’t available.
A new R&D hub for defense tech
Airless UGV wheels are just the latest in a growing list of creative fixes forced by the Russia-Ukraine war. The constant need for better drones and robots has turbocharged the country’s tech sector, which has grown from a handful of defense companies before the invasion to hundreds today. Most of the companies building out the new hardware are Ukrainian, but the war has also attracted a number of American defense startups that have set up shop there, drawn in by the change to their designs in the real world. The country’s capital city has attracted so much tech sector interest that some have even ascribed it the moniker: “Mil-Tech Valley.”
Almost one year ago, paleontologists finally settled a longstanding debate about Tyrannosaurus rex, arguably Earth’s most famous dinosaur. After reviewing decades of mounting evidence, researchers documented around 150 morphological differences across multiple supposed juvenile T. rex skeletons. Instead of young dinosaurs, these were actually adult examples of an entirely separate species now known as Nanotyrannus lancensis.
While Nanotyrannus was dwarfed by its massive relative, itstill reached an impressive 18 feet long and weighed as much as 1,500 pounds. But while it may have lost some of its cultural cache during the rebrand, a well-preserved specimen nicknamed Jodi may still sell for upwards of $9 million at an upcoming auction.
“It completely changes what we understand about the Cretaceous,” Cassandra Hatton, Sotheby’s head of science and natural history, said during a recent interview.
Paleontologists first suspected the existence of a separate species after discovering a uniquely proportioned skull at Montana’s Hell Creek Formation in 1946. Back-and-forth arguments about the dinosaur’s true identity continued for the next 80 years, but the ramifications weren’t simply a matter of semantics. If confirmed, it meant T. rex wasn’t the only tyrannosauroid roaming North America during the late Cretaceous period.
Jodi is a relatively new find. Named after the Montana rancher who found it, Jodi Pierson, the skeleton was excavated at the Hell Creek Formation in 2019, and is estimated to be about 55 percent complete. It features all four of its claws as well as 35 teeth in a nearly complete skull. According to the Sotheby’s auction listing, Jodi stands about 6.5 feet tall and measures 19.6 feet from nose to tail. The mounted dinosaur includes all of its surviving fossilized bones along with 3D-printed and sculpted additions to fill in the paleontological gaps.
Jodi will officially go up for auction on October 27 in New York City, where she is expected to sell for $6–8 million. The final price may still surprise bidders, however. In July, auctioneers estimated that a nearly complete T. rex named Gus would sell for $30 million. Gus blew that out of the water, ultimately fetching over $50 million.
Marine biologists are sounding the alarm on behalf of the Galápagos Islands’ marine iguana (Amblyrhynchus cristatus). Without tightened regulations on the often abused exotic pet trade, researchers warn that a recent “strange uptick” in illegal animal trafficking combined with this season’s Super El Niño is further endangering the already vulnerable reptiles living on the Eastern Pacific archipelago.
“They are already shrinking in size and facing mass mortality, either by starvation or by trying to swim longer distances in search of food,” Juan José Alava, a marine ecotoxicologist at Canada’s Simon Fraser University, explained in a recent letter published in Science.
The marine iguana family encompasses at least 11 known subspecies, each specially evolved to live on the Galápagos Islands. They are the only reptiles in the world capable of foraging underwater for macroalgae, which makes up the majority of their diet. Although iguana colonies remain relatively stable, the International Union for Conservation of Nature (IUCN) still lists them as Vulnerable due to predators, mounting pollution issues, and cyclical El Niño events. Ten of the 11 recognized subspecies are also locally classified as either Critically Endangered or Endangered. Sale of iguanas is banned under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but a recent uptick in illegal trafficking along with increasingly dramatic climate shifts is adding more stress to the situation.
Ecuadorian authorities have caught people attempting to smuggle iguanas multiple times this year. In May, officials discovered at least a dozen animals inside handbags at an airport that were bound for illegal markets. Law enforcement found another 32 tied up inside a suitcase intended for similar buyers in August. Many trafficked iguanas won’t survive the stress and rough handling, but even rescued reptiles face challenges. Because subspecies are evolved to live on specific islands, ecologists must test each rescued iguana’s DNA to determine where to return them.
Smuggling hasn’t been seen within the Galápagos Marine Reserve itself, but Alava and his colleagues theorize that smugglers are capturing iguanas near Ecuador’s coastal shorelines. Traffickers then obtain CITES permits that falsely declare the reptiles are captive bred in other nations, even though no such authorized facilities actually exist. Often, smugglers are only engaged in the industry out of financial necessity or coercion.
“Artisinal fishing communities from Galapagos and coastal Ecuador, who are facing severe socioeconomic hardship and expanding organized crime activities, may feel pressured to participate in this international black market,” the letter’s authors wrote.
Conservationists are now urging a multifaceted approach to protect the animals. CITES representatives need to close existing permit loopholes, while the Ecuadorian government should focus on simultaneously breaking up organized crime and providing economic aid to struggling communities.
“Maintaining global ocean observing systems is essential, and extreme marine event forecasting and response capabilities are improving,” the authors wrote. “But responsibility and action remain fragmented across environmental [organizations], fisheries, and emergency management, and public health agencies.”
A small puncture wound through a 75,000-year-old Neanderthal shoulder blade may be the earliest evidence of death by spear on humanity’s family tree. Given forensic details such as the entry angle and overall damage, researchers believe the injury was made as an intentionally fatal “heart shot” that killed the ancient hominin within moments. The discovery is detailed in a study published today in the journal Scientific Reports.
In addition to the grisly injury, the nearly translucent bone itself makes this evidence even more striking.
“It’s extraordinary to have a perfectly preserved scapula from 75,000 years ago. These bones are so thin that you often don’t get complete scapulae from modern burials,” explained University of Cambridge archaeologist and study co-author Emma Pomeroy. “We were able to lift it out in one piece from under almost eight meters [roughly 26 feet] of rock and sediment.”
Pomeroy and her colleagues excavated the remains from inside Shanidar Cave, an archaeological site in Iraqi Kurdistan famous for containing evidence of ritualistic Neanderthal burials. The roughly 0.6 inch, nearly circular perforation on the bone was likely made with a wooden spear, since a stone or flint tip would create a flatter injury and leave behind microscopic mineral shards. The individual who inflicted the fatal injury drove the spear downward through the victim’s left chest cavity from the front, piercing major arteries and the lungs before creating the hole in the left scapula.

Remnants of a wooden spear weren’t found near the Neanderthal’s remains, which is understandable since the material often decomposes so quickly. That said, prior archaeological digs have revealed similar prehistoric wooden weapons dating as far back as 400,000 years. Pomeroy’s team believes a rounded spear carved from wood almost certainly caused the killing blow.
“Holes left by recreations of spears from this time are an excellent fit for the one we found in the Neanderthal scapula. That early technology absolutely works for this wound,” said Pomeroy.
Although it’s possible that a mishap like a hunting accident was the cause of death, Pomeroy argues the cumulative details suggest something far more purposeful.
“The position of the wound and the force required to push it right through the Neanderthal’s body bear the hallmarks of an intended kill shot directed towards the heart,” she added.
Another major injury the victim sustained before the possible stabbing supports this hypothesis—and complicates the story. In addition to the scapula, archaeologists documented a pair of left ribs, a right rib fragment, a nearly complete right hand, and seven teeth. Collectively, the remains indicate the Neanderthal was about 45 years old at the time of death. However, dental damage reveals the individual suffered a severe blunt-force blow to the front of the face at least a year before death. This injury split a lower front incisor lengthwise and even rotated some teeth inward.
“There’s no doubt that [they] would have had difficulty communicating and been in absolute agony for a long period of time,” said Pomeroy.
Despite this blow to the mouth, the Neanderthal survived for months or even years. This was only possible because others must have cared for the individual, including duties as simple as preparing softer foods to eat. In this sense, there is a distinct possibility the spear wound was a final, merciful act by someone close to them. According to Pomeroy, the prehistoric scene showcases both the highs and lows of what it means to be a human.
“On the one hand, we have evidence of a terribly violent end,” she said. “On the other, this was clearly an individual who was cared for during their lifetime.”
