Dragonflies share humans' red-light sensing trick, detecting wavelengths near 720 nm

Sometimes, different organisms can evolve the same ability independently, a process called parallel evolution. A new study from Osaka Metropolitan University (OMU) has found that dragonflies sense red light similarly to mammals, ...

Single-shot imaging captures more information about ultrafast microscopic processes than previously possible

Researchers have developed a new imaging technique that captures more information about ultrafast processes in the microscopic world than was previously possible. The technique offers scientists a powerful new tool to observe ...

What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

One DNA letter can trigger complete sex reversal

Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding ...

Houston, we have a problem ... with the toilet

After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.

Skin can 'pre-learn': Priming cells for regeneration before injury

It is well known that students who prepare in advance perform better in exams. Now, it appears that the skin can do the same. Rather than scrambling to repair itself only after injury occurs, a Korean research team has demonstrated ...

Why anti-cancer drugs do not always live up to expectations

For more than a decade, a class of drugs called BET inhibitors has been tested in cancer trials with high expectations. The biology looked promising. Many cancers depend on oncogenes that "Bromo- and Extra-Terminal domain" ...

AI uncovers hidden immune defenses inside bacteria

Researchers at the Massachusetts Institute of Technology (MIT) have discovered thousands of new proteins that protect bacteria from virus attacks using an AI system called DefensePredictor. What would usually take months ...

DNA evidence reveals a Stone Age population collapse in France

By analyzing DNA of ancient skeletons at a Neolithic burial site near Paris, an international team of researchers has uncovered evidence of a dramatic population replacement 5,000 years ago. The findings indicate that the ...

A 'stemness checkpoint' helps control stem cell identity

A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...

Emperor penguins listed as endangered species: IUCN

The emperor penguin has been declared an endangered species as climate change pushes the icon of Antarctica a step closer to extinction, the global authority on threatened wildlife announced on Thursday.

New study reveals the depth of children's nuclear anxiety

As geopolitical tensions rise globally, a new study published in Critical Studies on Security warns that the shadow of the "mushroom cloud" is weighing heavily on the next generation. The research paper, titled "Mushrooms, ...

New Hampshire ski industry concerned about climate change

New research out of the University of New Hampshire reveals that the majority of New Hampshire ski industry professionals are concerned about the effects of global warming on the ski industry, which generates close to $278.8 ...

March smashes heat records for continental US

March's persistent unseasonable heat was so intense that the continental United States registered its most abnormally hot month in 132 years of records, according to federal weather data. And the next year or so looks to ...

Soaring petrol prices are hurting more than your wallet

Australians don't need an economist to tell them they're hurting at the petrol pump. They feel it every time they pull into a service station, every time they rethink a planned holiday, or every time they've had to squeeze ...

Split shift: A surprising twist in the biology of aging

A new Yale study of flatworms, a species with the unique ability to regenerate, reveals that disruptions in the body's internal map of cellular organization may play a part in age-related decline.

New method rapidly analyzes cell proteins and metabolites

Researchers at Cedars-Sinai have developed a fast, new technique for analyzing cells, described in the journal Angewandte Chemie. The approach, called single-injection multi-omics analysis by direct infusion (SMAD), can detect ...

Why cats stop eating—it's not just fullness

Why do cats often leave food unfinished? Many cat owners have experienced this puzzling behavior. Domestic cats are well known for eating multiple small meals throughout the day, a pattern thought to reflect their evolutionary ...

AI reveals hidden connections within legal systems

As governments worldwide explore how artificial intelligence can transform decision-making, a recent study from Sultan Qaboos University demonstrates how AI can uncover hidden connections within legal systems—offering a powerful ...
