| Study identifies new way to attack herpesviruses Posted: 25 Jan 2022 06:30 AM PST A new study has opened the door to a new approach to attacking herpesviruses. The study demonstrated that targeting 2 metal ion-dependent enzymes of human herpesviruses with 2 compounds, AK-157 and AK-166, can inhibit the replication of the virus. The finding provides new opportunities to developing agents against herpesviruses. |
| Fast, cheap test can detect COVID-19 virus’ genome without need for PCR Posted: 24 Jan 2022 04:49 PM PST Researchers have developed a new test for COVID-19 that combines the speed of over-the-counter antigen tests with the accuracy of PCR tests that are processed in medical labs and hospitals. |
| Posted: 24 Jan 2022 12:10 PM PST Genetic analyses helped identify a new cryptic shark species of the genus Squatina from the Western Atlantic Ocean. |
| How environment and genomes interact in plant development Posted: 24 Jan 2022 12:10 PM PST A new study could help to breed more resilient crops as well as shed light on mechanisms that play a critical role in plant growth. The study focuses on how phenotypic plasticity, or the way a given trait can differ as a result of environmental conditions, influences the growth of sorghum. |
| Urban Britain’s potential as a ‘grow your own veggies’ nation Posted: 24 Jan 2022 08:50 AM PST Scientists set out to discover if there is sufficient green space, such as private gardens, parks and other recreational areas, within our towns and cities to grow enough fresh food to feed local populations. |
| Overweight dogs respond well to high-protein, high-fiber diet Posted: 24 Jan 2022 08:50 AM PST A study of overweight dogs fed a reduced calorie, high-protein, high-fiber diet for 24 weeks found that the dogs' body composition and inflammatory markers changed over time in ways that parallel the positive changes seen in humans on similar diets. The dogs achieved a healthier weight without losing too much muscle mass, and their serum triglycerides, insulin and inflammatory markers all decreased with weight loss. |
| Study demonstrates accuracy of less invasive technique for monitoring wildlife health Posted: 24 Jan 2022 08:50 AM PST A recent study finds a technique that uses dried spots of blood to measure health indicators in elephants is comparable to techniques that use larger blood samples and require immediate cold storage -- technology that is not always available when monitoring animals in the wild. |
| Calf personality, feeding, and growth: When one style doesn’t fit all Posted: 24 Jan 2022 08:50 AM PST In a natural setting, cows and nursing calves together set the feeding schedule for the calf, and calves wean gradually, completing weaning at varying ages. By contrast, in artificial rearing systems with minimal cow-calf contact, the weaning schedule may be strictly determined, with reductions of milk intake based solely on the calf's age. But how well do different calves thrive under different feeding and weaning systems? |
| Posted: 24 Jan 2022 08:50 AM PST Chimpanzees don't automatically know what to do when they come across nuts and stones. Researchers have now used field experiments to show that chimpanzees thus do not simply invent nut cracking with tools, but need to learn such complex cultural behaviors from others. Their culture is therefore more similar to human culture than often assumed. |
| Hippos recognize each other’s voices, respond differently to calls of strangers Posted: 24 Jan 2022 08:48 AM PST Hippopotamuses are rather vocal animals. Their 'wheeze honk' calls can be heard over long distances, leading researchers to suspect the calls play an important role in maintaining social groups. Now, a new study shows that hippos recognize each other's voices. They also respond less aggressively to the calls of a neighbor compared to those of a stranger. |
| Green backyards help increase urban climate resilience: Here is how Posted: 24 Jan 2022 07:39 AM PST Taking into account a variety of trees and green structures in four otherwise similar residential courtyards, a new study evaluates their effects on thermal comfort, biodiversity, carbon storage and social interaction. The authors show that those courtyards with more green structures yield considerably better results than those with fewer, and in their cooling capacity have a significant impact on people's thermal comfort. |
| Transparency in butterflies, from A-Z: It’s more of a superpower than we thought Posted: 24 Jan 2022 07:38 AM PST Wing transparency as a flexible weapon for self-defense is one of many findings from a multi-year study spanning the physics, biology, ecology, and evolution of transparency in butterflies conducted by several groups. |
| Exploring fish flow from fisheries to supper Posted: 21 Jan 2022 01:55 PM PST A recently published study brought together experts from the fields of oceanography, genetics, ecology, fisheries biology, and social sciences to develop unprecedented insights into the natural and commercial flow of fish. |
