Scientists have long known the brain's hippocampus is crucial for long-term memory. Now a new study has found the hippocampus also plays a role in short-term memory and helps guide decision-making. The findings shed light on how the hippocampus contributes to memory and exploration, potentially leading to therapies that restore hippocampal function, which is impacted in memory-related aging and...

A research group of scientists from North America, Europe and Africa concluded that animals' ability to respond to climate change likely depends on how well they modify their habitats, such as nests and burrows.

The visual thalamus is classically known to relay visual stimuli coming from the retina to the cerebral cortex. Researchers now show that although neurons in the mouse visual thalamus connect to both eyes, they establish strong functional connections only with one retina. These results settle partly contradictory results of earlier studies and demonstrate how important it can be to complement...

People who are physically active during childhood have higher cognitive functions in later life. Participants who exercised when they were children did better on cognitive tests regardless of their current age. However, no such relationship was found between task performance and post-childhood exercise -- suggesting that exercise during childhood is particularly important for brain development and...

Footprints from at least six different species of dinosaur -- thought to be the very last dinosaurs to walk on UK soil 110 million years ago -- have been found in Kent.

Fruit flies have found at least two solutions to the problem of sorting their sex chromosomes: a matter of life and death.

Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study.

In a new study, researchers determined that the common blood pressure medication, losartan, is not effective in reducing hospitalization for mildly-ill COVID-19 outpatients.

It could be a milestone on the path to detecting life on other planets: Scientists detect a key molecular property of all living organisms from a helicopter flying several kilometers above ground. The measurement technology could also open up opportunities for remote sensing of the Earth.

A science-based intervention relieved hiccups for 92% of 249 users who self-reported the effectiveness of the tool. =

Lake Victoria, which came under the spotlight in 2004 by the documentary 'Darwin's nightmare', is not only suffering from the introduction and commercialization of the Nile perch: A study has highlighted other worrying phenomena, particularly climatic ones, which have an equally important impact on the quality of the lake's waters.

It is possible to re-create a bird's song by reading only its brain activity, shows a first proof-of-concept study. The researchers were able to reproduce the songbird's complex vocalizations down to the pitch, volume and timbre of the original. The study is a first step towards developing vocal prostheses for humans who have lost the ability to speak.

Researchers decipher the basic biology of neutrophil swarming and now show that the cells also evolved an intrinsic molecular program to self-limit their swarming activity. The study elucidates how swarming neutrophils become insensitive to their own secreted signals that brought the swarm together in the first place. This process is crucial for the efficient elimination of bacteria in tissues.

Forest fires have crept higher up mountains over the past few decades, scorching areas previously too wet to burn, according to researchers. As wildfires advance uphill, a staggering 11% of all Western US forests are now at risk.

Researchers discovered that the enzyme RNA polymerase II recognizes and transcribes artificially added base pairs in genetic code, a new insight that could help advance the development of new vaccines and medicines.

In a bid to find or refine laboratory research models for cancer that better compare with what happens in living people, scientists report they have developed a new computer-based technique showing that human cancer cells grown in culture dishes are the least genetically similar to their human sources.

Researchers improve energy density in a novel electric vehicle battery - a step toward a more cost-effective, easily recycled battery that would allow EVs to travel farther and charge faster at a low cost.

Sour taste does not have the nearly universal appeal that sweet taste does. Slightly sour foods or drinks such as yogurt and lemon juice are yummy to many, but such highly sour foods as spoiled milk are yucky, even dangerous. Like humans, many other animals, including insects, prefer slightly acidic over very acidic foods.

In a new study using variant virus recovered from one of the original travelers, researchers in the US and Japan have found that vaccination with an mRNA vaccine induces antibody responses that would protect humans from infection with the gamma/P.1 variant.

Climate change will shape the future of coastal communities, with flood walls, elevated structures and possibly even floating cities used to combat sea level rise. New research has found that managed retreat -- moving buildings, homes or communities off of the coast or away from floodplains -- must be part of any solution.

How much do traditional practices contribute to the protection of local biodiversity? Why and how are sacred groves locally valued and protected, and how can this be promoted and harnessed for environmental protection? Researchers have examined the backgrounds of this form of local environmental protection in Baneh County, Iran.

Researchers have found SARS-CoV-2 in the testes of infected hamsters. The authors think this may represent what could occur in men with mild to moderate COVID-19 disease.

The surface of a material often has properties that are very different from the properties within the material. An international research team has now succeeded in investigating the surfaces of transparent crystals using powerful irradiation from lasers.

The combination of sea level rise, tides, storm surge and waves has increased the overtopping of natural and artificial coastal protection by nearly 50% in the last two decades.
