Scientists have uncovered new evidence that modern humans inherited DNA from two previously unknown ancient human relatives, revealing another surprising chapter in our evolutionary history. The discovery was made using a new genetic analysis method that can identify traces of long-extinct human groups even when no ancient DNA from them has ever been found. The […]

Mars is slowly losing parts of its atmosphere to space, and scientists have discovered that the process may be driven by giant waves created where the solar wind meets the planet’s upper atmosphere. The new research, led by Boston University, shows that these waves act much like wind blowing across the surface of a lake, […]

Neptune’s small inner moons may actually be the broken remains of a much older family of icy worlds that were destroyed billions of years ago, according to a new study using NASA’s James Webb Space Telescope (JWST). Scientists believe the evidence points to a dramatic event in the distant past, when Neptune captured its largest […]

Doctors usually diagnose dementia only after memory and thinking problems become noticeable. By that stage, damage to the brain has often been developing for many years. Scientists are therefore searching for ways to detect the disease much earlier, when treatments may have a better chance of slowing its progress. A new study from researchers at […]

Many people think of migraine as simply a painful headache, but it is actually a complex neurological condition. Around one in three people with migraine experience an aura before the headache begins. An aura may cause flashing lights, blind spots, wavy lines or numbness that usually lasts for a short time before the pain starts. […]

Children’s eating habits may shape their heart health decades later, according to a major new study. Scientists found that people who regularly drank sugary beverages while growing up were more likely to develop high blood pressure as adults, while choosing whole fruit instead appeared to lower that risk. The findings were published in Circulation by […]

Most people know that the kidneys clean the blood, but far fewer realise they also help protect the brain. Growing research shows that chronic kidney disease can damage memory, thinking and concentration, making brain health another major concern for millions of patients around the world. Researchers summarised evidence showing that kidney disease affects much more […]

Scientists have discovered that the sleep problems seen in Alzheimer’s disease may not be caused directly by harmful protein plaques as previously believed. Instead, the brain’s own immune system may be playing a much larger role, opening the door to new treatment possibilities. Sleep problems are one of the earliest and most common symptoms of […]

What if a computer did not rely on electronic chips or tiny transistors, but instead used hundreds of microscopic particles moving through a liquid? That futuristic idea has now become a reality in a laboratory, where researchers have created a completely different kind of computer that performs calculations using the natural movement of tiny particles.

Hydrogen peroxide is a common chemical found in hospitals, factories and laboratories around the world. It is used to disinfect medical equipment, make paper, clean semiconductor chips and support many other industrial processes. Although it is widely used, making hydrogen peroxide usually requires large factories, high energy use and complicated manufacturing methods. Now, researchers have […]

Europa, one of Jupiter’s largest moons, has fascinated scientists for decades because it may hide a vast ocean of liquid water beneath its thick icy surface. Since liquid water is one of the key ingredients needed for life, Europa is considered one of the most promising places in our solar system to search for signs […]

Many people know that sugary drinks can lead to weight gain and diabetes, but a new study suggests they may also increase the risk of high blood pressure later in life. The research shows that drinking soda, sports drinks, and even large amounts of fruit juice from childhood into adulthood could have lasting effects on […]

Millions of Americans may have cholesterol levels that are now considered too high under newly updated heart health guidelines, according to a new study from Mass General Brigham. The research suggests that many people who could benefit from treatment are either not taking cholesterol-lowering medicine or are not receiving enough treatment to reach the latest […]

Rheumatoid arthritis is a long-term autoimmune disease in which the immune system mistakenly attacks healthy joints. This causes pain, swelling, stiffness, and gradual damage that can make everyday activities difficult. Although modern medicines help many people, some patients do not respond well or develop unwanted side effects, creating a need for better treatments. A new […]

Alzheimer’s disease is the most common form of dementia and affects millions of people worldwide. It slowly destroys memory, thinking, and the ability to carry out everyday activities. Although scientists have developed medicines that can ease some symptoms, there is still no cure, and one of the biggest challenges is that treatments do not work […]

Migraines are far more than ordinary headaches. Many people experience severe throbbing pain, nausea, and sensitivity to light and sound that can last for hours or even days. Some people also experience an aura before the headache begins, which may include flashing lights, blurry vision, zigzag lines, or tingling sensations. A new study suggests that […]

Knitted fabrics are usually associated with warm sweaters, scarves, and blankets. But researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have shown that knitting can do much more than keep people warm. They have created a new type of smart fabric that can change shape, act like a switch, […]

Barnard’s Star is one of the most famous stars in the night sky for astronomers because it is so close to Earth. Located just under six light-years away, it is the second-closest star system after Alpha Centauri. In 2025, scientists confirmed that four small planets orbit this nearby star. Now, a new study has revealed […]
