Memory helps us evaluate situations on the fly, not just recall the past

Science Daily - 13 hours 26 min ago
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 neurodegenerative diseases such as dementia, the study authors said.

Animals' ability to adapt their habitats key to survival amid climate change

Science Daily - 13 hours 27 min ago
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.

In the visual thalamus, neurons are in contact with both eyes but respond to only one

Science Daily - 18/06/2021
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 structural data with functional analyses.

How childhood exercise could maintain and promote cognitive function in later life

Science Daily - 18/06/2021
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 long-term cognitive health.

Footprints discovered from the last dinosaurs to walk on UK soil

Science Daily - 18/06/2021
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.

Evolution: Two routes to the same destination

Science Daily - 18/06/2021
Fruit flies have found at least two solutions to the problem of sorting their sex chromosomes: a matter of life and death.

The Earth has a pulse -- a 27.5-million-year cycle of geological activity

Science Daily - 18/06/2021
Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study.

Researchers find losartan is not effective in reducing hospitalization from mild COVID-19

Science Daily - 18/06/2021
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.

Scientists detect signatures of life remotely

Science Daily - 18/06/2021
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.

The end of Darwin's nightmare at Lake Victoria?

Science Daily - 18/06/2021
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.

Researchers translate a bird's brain activity into song

Science Daily - 18/06/2021
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.

Mountain fires burning higher at unprecedented rates

Science Daily - 18/06/2021
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.

Most cancer cells grown in a dish have little in common with cancer cells in people, research finds

Science Daily - 18/06/2021
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.

Altered microstructure improves organic-based, solid state lithium EV battery

Science Daily - 18/06/2021
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.

Vaccination, previous infection, protect against COVID-19 gamma/P.1 variant in animal model

Science Daily - 18/06/2021
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.

Sacred natural sites protect biodiversity in Iran

Science Daily - 18/06/2021
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.

New study finds SARS-CoV-2 can infect testes

Science Daily - 18/06/2021
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.

Tailored laser fields reveal properties of transparent crystals

Science Daily - 18/06/2021
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.
