Scientists can tell where a mouse is looking and located based on its neural activity      (via sciencedaily.com)     Original source 

Researchers have paired a deep learning model with experimental data to 'decode' mouse neural activity. Using the method, they can accurately determine where a mouse is located within an open environment and which direction it is facing, just by looking at its neural firing patterns. Being able to decode neural activity could provide insight into the function and behavior of individual neurons or even entire brain regions.

Increasingly similar or different? Centuries-long analysis suggests biodiversity is differentiating and homogenizing to a comparable extent      (via sciencedaily.com)     Original source 

The tendency of communities and the species within them to become more similar or more distinct across landscapes -- biotic homogenization and differentiation -- are approximately balanced, according to a new study. This analysis is the first of its kind to provide a comprehensive assessment of how local and regional biodiversity changes combine across landscapes over centuries.

New evidence shows UK solar parks can provide for bees and butterflies      (via sciencedaily.com)     Original source 

A new study shows that UK solar parks, if managed correctly, can provide vital resources to help stem the decline in the nation's bees and butterflies. The new research provides peer-reviewed field data of insect pollinators at solar parks in the UK, covering 15 sites.

New system triggers cellular waste disposal      (via sciencedaily.com)     Original source 

Established treatments for cancer and other diseases often focus on inhibiting harmful enzymes to mitigate their effects. However, a more innovative approach has emerged: harnessing the cell's natural waste disposal system not just to deactivate but to entirely eradicate these proteins. Researchers have previously demonstrated the efficacy of this approach through two distinct methods. Now they unveil a third system capable of targeting and disposing of previously inaccessible proteins.

Scientists may have cracked the 'aging process' in species      (via sciencedaily.com)     Original source 

Research shows the relationship between a species' age and its risk of going extinct could be accurately predicted by an ecological model called the 'neutral theory of biodiversity.'

Pollinator's death trap turns into nursery      (via sciencedaily.com)     Original source 

In a group of plants that is famous for luring its pollinators into a death trap, one species offers its flowers as a nursery in exchange. The discovery blurs the line between mutualism and parasitism and sheds light on the evolution of complex plant-insect interactions.

Asexual propagation of crop plants gets closer      (via sciencedaily.com)     Original source 

When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.

Root microbes may be the secret to a better tasting cup of tea      (via sciencedaily.com)     Original source 

You'd think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. But a new study shows that the making of a delicious cup of tea depends on another key ingredient: the collection of microbes found on tea roots. By altering that assemblage, the authors showed that they could make good-quality tea even better.

Ancient retroviruses played a key role in the evolution of vertebrate brains      (via sciencedaily.com)     Original source 

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed 'RetroMyelin,' is likely a result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events occurred separately in each of these groups.

Pesticides to help protect seeds can adversely affect earthworms' health      (via sciencedaily.com)     Original source 

While pesticides protect crops from hungry animals, pesky insects, or even microbial infections, they also impact other vital organisms, including bees and earthworms. And today, research reveals that worms are affected by the relatively small amounts of chemicals that can leach out of pesticide-treated seeds. Exposure to nonlethal amounts of these insecticides and fungicides resulted in poor weight gain and mitochondrial DNA (mtDNA) damage in the worms.
