Natural compound found in broccoli reawakens the function of potent tumor suppressor
Long associated with decreased risk of cancer, broccoli and other cruciferous vegetables -- the family of plants that also includes cauliflower, cabbage, collard greens, Brussels sprouts and kale --…
Owning a dog is influenced by our genetic make-up
Scientists have studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation explains more than half…
Scientists propose rethinking 'endangered species' definition to save slow-breeding giants
Conservation decisions based on population counts may fail to protect large, slow-breeding animals from irrevocable decline, according to new research.
Sedimentary, my dear Johnson: Is NASA looking at the wrong rocks for…
While volcanic, igneous rock predominates on Mars, virtually the entire Earth fossil record comes from sedimentary rocks. Addressing the problem, Swedish scientists have begun compiling evidence of…
Earliest evidence of the cooking and eating of starch
New discoveries made at the Klasies River Cave in South Africa's southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically modern…
Australian islands home to 414 million pieces of plastic pollution
A survey of plastic pollution on Australia's Cocos (Keeling) Islands has revealed the territory's beaches are littered with an estimated 414 million pieces of plastic debris. The study estimated…
Surprising research result: All immature cells can develop into stem cells
A new study challenges traditional knowledge of stem cell development. The study reveals that the destiny of intestinal cells is not predetermined, but instead determined by the cells' surroundings.…
Heavily processed foods cause overeating and weight gain, study finds: Small-scale trial…
People eating ultra-processed foods ate more calories and gained more weight than when they ate a minimally processed diet, according to results from a new study. The difference occurred even though…
Nearly a quarter of West Antarctic ice is now unstable
In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study.
Bedbugs evolved more than 100 million years ago
Bedbugs -- some of the most unwanted human bed-mates -- have been parasitic companions with other species aside from humans for more than 100 million years, walking the earth at the same time as…
Galaxy blazes with new stars born from close encounter
The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new…
How we make complex decisions: Neuroscientists identify a brain circuit that helps…
Neuroscientists have identified a brain circuit that helps break complex decisions down into smaller pieces. The study sheds light on how the brain reasons about probable causes of failure after a…
Brain's insular cortex processes pain and drives learning from pain
Neuroscientists have discovered an area of the brain, the insular cortex, that processes painful experiences and thereby drives learning from aversive events.
Brain changes in autism traced to specific cell types
Changes in gene activity in specific brain cells are associated with the severity of autism in children and young adults with the disorder, according to a new study.
Scientists find new type of cell that helps tadpoles' tails regenerate
Researchers have uncovered a specialized population of skin cells that coordinate tail regeneration in frogs. These 'Regeneration-Organizing Cells' help to explain one of the great mysteries of nature…
Chewing gums reveal the oldest Scandinavian human DNA
The first humans who settled in Scandinavia more than 10,000 years ago left their DNA behind in ancient chewing gums, which are masticated lumps made from birch bark pitch.
As bumblebee diets narrow, ours could too: Fewer plants cause developmental delays…
A new study reveals the loss of plant diversity harms the humble bumblebee at a critical stage in its development from egg to adult.
Virutally energy-free superfast computing invented by scientists using light pulses
A new invention uses magnets to record computer data which consume virtually zero energy, solving the dilemma of how to create faster data processing speeds without high energy costs.
Neanderthals and modern humans diverged at least 800,000 years ago, research on…
Neanderthals and modern humans diverged at least 800,000 years ago, substantially earlier than indicated by most DNA-based estimates, according to new research.
Experimental brain-controlled hearing aid decodes, identifies who you want to hear
Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing…
Jawless fish take a bite out of the blood-brain barrier
A jawless parasitic fish could help lead the way to more effective treatments for multiple brain ailments, including cancer, trauma and stroke. Researchers borrowed molecules from the immune system of…
New AI sees like a human, filling in the blanks
Computer scientists have taught an artificial intelligence agent how to do something that usually only humans can do -- take a few quick glimpses around and infer its whole environment, a skill…
A new way of diagnosing and treating disease
Researchers have developed a specialized microscope that has the potential ability to both diagnose diseases that include skin cancer and perform incredibly precise surgery -- all without cutting…
From Earth's deep mantle, scientists find a new way volcanoes form
Far below Bermuda's pink sand beaches and turquoise tides, geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone -- a layer rich in…
