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 […]
