Study provides oldest direct evidence of our ancient cousins killing the big cats, perhaps not just for their meat...

Researchers catalogue more than 3,000 different types of cell in our most complex organ.

Spring is a dangerous time to be a female European common frog. After a winter-long hibernation, these amphibians congregate in shallow ponds to mate and lay eggs. The gatherings can turn ugly fast; male frogs, which vastly outnumber females, will regularly harass, intimidate, and coerce their counterparts into mating....

Neuron activity shows that the brain uses different systems for counting up to four, and for five or more....

Euclid has found its ‘lost’ guide stars as a software patch has solved its navigation woes and the next six years of observation schedules have been redesigned to avoid stray sunlight: it’s the end of an interesting commissioning phase and Euclid will now undergo its final testing in full ‘science mode’.

Japanese scientist Kikunae Ikeda first proposed umami as a basic taste — in addition to sweet, sour, salty and bitter — in the early 1900s. About eight decades later, the scientific community officially agreed with him....

Lions have long been perceived as Africa’s, if not the world’s, most fearsome terrestrial predator,the “king of beasts”. Wildlife’s fear of humans may, however, be far more powerful and all-prevailing, as recent global surveys show that humans kill prey at much higher rates than other predators, due partly to...

To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In the current issue of the scientific journal Science Advances, they describe how...

Moungi Bawendi, Louis Brus and Alexei Ekimov receive the prize for their work on glowing nanoparticles that are used in fields from electronics to surgery.

Katalin Karikó and Drew Weissman developed immunizations amid an unprecedented pandemic at record-breaking speed.

Lung cancer is the leading cause of cancer-related deaths in the United States. Some tumors are extremely small and hide deep within lung tissue, making it difficult for surgeons to reach them. To address this challenge, UNC –Chapel Hill and Vanderbilt University researchers have been working on an extremely bendy but sturdy...

Researchers publicly call out theory that they say is not well supported by science, but that gets undue attention....

RNA for the first time recovered from an extinct species A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct...

There has been a real race among scientists to create a technology that enables easy protein sequencing. Professor of Chemical Biology Giovanni Maglia of the University of Groningen has now found the missing piece in the puzzle: a way to transport a protein through a nanopore, which allows sequencing of proteins in a simple,...

FAU researchers provide the first quantified observations of the “birth” of purpose in human infants, as they recognize their causal powers and transition from spontaneous to intentional behavior.

As US policymakers spar over how to regulate research involving potentially harmful pathogens, a report finds that it will be difficult to do so without compromising studies that are necessary for creating vaccines and life-saving therapies....

Because the areas around adult trees are selectively hostile to their seedlings, more tree species can be packed into tropical forests.

Sticking out your tongue while doing delicate work with your hands reveals a history of evolutionary relationships.

This summer NSF decided to cancel or curtail 67—more than half—of the 131 projects and activities funded for the 2023–24 austral summer after concluding it couldn’t provide them with the necessary logistical support.

Some Japanese researchers feel that AI systems trained on foreign languages cannot grasp the intricacies of Japanese language and culture.
