| Children eat what they like, but food intake driven more by what they dislike Posted: 22 Feb 2022 01:18 PM PST It is often said that 'children eat what they like,' but the results of a new study by nutritionists and sensory scientists suggests that when it comes to meals, it is more accurate and more relevant to say, 'children do not eat what they dislike.' |
| A new way to disarm antibiotic resistance in deadly bacteria Posted: 22 Feb 2022 10:53 AM PST Scientists think they may have uncovered a whole new approach to fighting antibiotic-resistant bacteria, which, if successful, would help address a health crisis responsible for more deaths every year than either AIDS or malaria. A team of researchers found a new way to impair antibiotic resistance in bacteria that cause human disease. The team made the bacteria vulnerable again to antibiotics by inhibiting a particular protein that drives the formation of resistance capabilities within the bacteria, called DsbA. |
| Food for thought: A high-fiber diet may reduce risk of dementia Posted: 22 Feb 2022 10:53 AM PST Researchers found that higher levels of dietary fiber are associated with a reduced risk of developing dementia. In a large-scale study, over 3500 Japanese adults completed a dietary survey and were then followed up for two decades. Adults who consumed more fiber, particularly soluble fiber, were less likely to go on to develop dementia. These findings may relate to interactions between the gut and the brain. |
| Posted: 22 Feb 2022 10:51 AM PST New research associates the presence of Caudovirales in gut microbiota to an improvement in cognitive functions and memory in humans, mice and flies. The results show that bacteriophages present in the gut microbiota influence the relationship between the microbiome and the brain. |
| Rats can estimate their timing accuracy Posted: 22 Feb 2022 09:51 AM PST Just like humans, rats are able to estimate a temporal error in their actions. This discovery opens up new avenues for identifying the mechanisms and brain structures which underlie the internal representation of time. |
| COVID-19 genetic risk variant protects against HIV, study finds Posted: 21 Feb 2022 12:52 PM PST The major genetic risk variant for severe COVID-19, one we inherited from Neandertals, is surprisingly common. A new study shows that the same gene variant that increases the risk of falling seriously ill with COVID-19 protects from another serious disease -- it reduces a person's risk of contracting HIV by 27 percent. |
| Accelerating melt rate makes Greenland Ice Sheet world’s largest ‘dam’ Posted: 21 Feb 2022 12:52 PM PST The world's second-largest ice sheet is melting from the bottom up -- and generating huge amounts of heat from hydropower. |
| Government guidelines insufficient to protect freshwater ecosystem from salt pollution Posted: 21 Feb 2022 12:51 PM PST Current water quality guidelines aren't protecting freshwater ecosystems from increasing salt pollution due to road de-icing salts, agriculture fertilizers, and mining operations, according to an international study. |
| Neurosciences: Innovative approach to treating brain diseases Posted: 18 Feb 2022 07:07 AM PST An impressive number of brain pathologies are closely linked to major cerebrovascular defects, which are currently impossible to treat due to a lack of drugs. The discovery is therefore particularly promising, as not only have they developed a new class of molecules that specifically correct these dysfunctions, they have also demonstrated their effectiveness in mouse models of radically different brain pathologies. |
