Giant Rift Valleys Hint Venus is Still Tectonically Active

This hemispheric view of Venus was created using radar observations, including images from NASA’s Magellan spacecraft. Magellan imaged more than 98% of Venus. Gaps in the Magellan coverage were filled with images from the Earth-based Arecibo radar. The composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation. Magellan launched on May 4, 1989, and was deployed from the cargo bay of Space Shuttle Atlantis on May 5, 1989. The spacecraft orbited Venus from August 10, 1990, until October 13, 1994 when the spacecraft was commanded to plunge into the atmosphere of Venus. Image credit: NASA / JPL-Caltech / USGS.

New 3D computer simulations from ETH Zurich show that young rift flanks on Venus stay tall and steep, while older ones flatten out over time.

In a new study of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), scientists found that embraces, touches and other reassuring gestures before competition for food were linked to more peaceful sharing, suggesting the roots of human social touch stretch back at least six million years.

Our Milky Way Galaxy Likely Underwent Disk Flip after Ancient Galactic Collision: Study

Using supercomputer simulations of galaxies like the Milky Way, Batrakov et al. found that galaxies with slowly rotating stellar haloes are more likely to have experienced a major ‘disk flip,’ where our Galaxy’s disk changed its orientation by more than 90 degrees. Image credit: Batrakov et al.

A head-on collision with another galaxy billions of years ago may have dramatically reoriented the Milky Way’s disk, according to new supercomputer simulations that reveal how violent mergers can leave spiral galaxies looking surprisingly normal today.

Puzzling Near-Earth Asteroid Turns Out to Be Comet with Weak Tail

This artist’s concept depicts a near-Earth asteroid with an elongated orbit; a few objects such as these can exhibit significant perturbations in their motion around the Sun and, like 1998 SH2, could turn out to be regular comets with a weak tail and coma. Image credit: NASA / JPL-Caltech.

The near-Earth object (875163) 1998 SH2, which is currently classified as an asteroid, has revealed a hidden identity: it’s actually a comet in disguise, according to a new study published in the journal Nature Astronomy.

Moderate Coffee and Caffeine Intake Poses Little Heart Risk, and May Even Help

Marcus et al. conclude that moderate caffeine or coffee consumption is safe for most adults and is linked to a lower risk of several cardiovascular conditions, including coronary heart disease, stroke, heart failure and atrial fibrillation, as well as hypertension and type 2 diabetes. Image credit: Sci.News.

In a new review paper, Dr. Gregory Marcus from the University of California, San Francisco and colleagues analyzed decades of research on how caffeine -- most often consumed as coffee -- affects the heart and its risk factors.

After decades of searching, astronomers have pinpointed the first of an estimated 10,000 stellar-mass black holes thought to lurk in Omega Centauri, the most massive stellar system in the Milky Way found so far, with a stellar mass of 3.6 million solar masses.

A new analysis suggests the four sub-Earth exoplanets orbiting Barnard’s star -- the Sun’s nearest single-star neighbor -- are likely packed with the deep-Earth mineral periclase, stripped of their atmospheres and far too hostile to support life.

Astronomers Detect Gamma-Ray Burst’s Magnetic Fingerprint

This illustration depicts Faraday rotation in the afterglow of a gamma-ray burst. A powerful jet (upper left) sends polarized radio waves outward through the thin wall of a surrounding bubble of magnetized gas called an HII region. As the light passes through this material, its polarization angle is twisted by the magnetic field. Because the effect is stronger at longer wavelengths, the red and blue waves, which represent different radio wavelengths, exit the bubble oscillating in different directions. By measuring this difference, astronomers were able to map the magnetic environment surrounding GRB 260310A for the first time. Image credit: NSF / AUI / NRAO / M. Weiss

Using NSF’s Very Large Array (VLA), astronomers made the first radio detection of polarized light and Faraday rotation from a gamma-ray burst afterglow, offering an unprecedented glimpse of the magnetic fields surrounding one of the Universe’s most powerful explosions.

Pluto’s Moon Charon May Still Be Slowing Its Spin, Study Suggests

This impressive view of Charon was captured on July 14, 2015. Charon’s color palette is not as diverse as Pluto’s; most striking is the reddish north (top) polar region, informally named Mordor Macula.

New research indicates that Pluto’s largest moon, Charon, may continue to lose rotational energy despite the pair’s long-standing tidal lock, offering scientists a rare glimpse into the hidden interiors of distant icy worlds.

Human-Dog Bond is Ancient, Universal and Strikingly the Same Everywhere: Study

Testing situation and hunters with their dogs -- examples from each of the four non-WEIRD societies: (a) pointing test in Mongolia, (b) unsolvable problem test in Vanuatu, (c) showing test in Mongolia, (d) Vanuatu, (e) Mongolia, (f) Madagascar, (g) Peru. Image credit: Bräuer et al., doi: 10.1038/s41598-026-57657-1.

New research spanning five continents and vastly different cultures -- from the steppes of Mongolia to the rainforests of the Pacific -- shows that hunting dogs and their owners cooperate, communicate and rely on each other in nearly identical ways, suggesting the relationship was forged in deep evolutionary time, perhaps 30,000 years ago.
