| 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.' |
| Sharp decline in basking shark sightings in California Posted: 22 Feb 2022 12:19 PM PST A recent study confirms a striking decrease in basking shark sightings in the California Current Ecosystem after the 1970s and 1980s and examines what is driving their presence and distribution. |
| Evidence grows for vaping's role in gum disease Posted: 22 Feb 2022 12:19 PM PST New studies highlight how e-cigarettes alter oral health and may be contributing to gum disease. The latest research finds that e-cigarette users have a unique oral microbiome that is less healthy than nonsmokers but potentially healthier than cigarette smokers, and measures worsening gum disease over time. |
| Light-based device uses a few drops of saliva to effectively test COVID-19 patients Posted: 22 Feb 2022 10:54 AM PST Researchers report on the development of a low-cost, portable, non-invasive device that uses light and saliva to test COVID-19 patients in less than 30 minutes. The results have shown that the device can detect very low concentrations of SARS-CoV-2 with a sensitivity of 91.2 percent and a specificity of 90 percent, similar to that of PCR but as fast as an antigen test. |
| 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. |
| New technology fused with photosynthetic life offers path to green energy Posted: 22 Feb 2022 10:53 AM PST Researchers have developed a patented hybrid device -- part living organism, part bio battery, capable of producing stored energy by increasing energy flow under light conditions where natural photosynthesis is normally inhibited. |
| Posted: 22 Feb 2022 10:52 AM PST Using wildlife cameras, scientists have provided new insights through a large-scale assessment of the occurrence and distribution of the Annamite striped rabbit and two Annamite dark muntjacs in six sites in Viet Nam and Laos. The team identified factors that influence the occurrence of these threatened endemics, and provided prediction maps for these sites. |
| Insect wingbeats will help quantify biodiversity Posted: 22 Feb 2022 10:52 AM PST Insect populations are plummeting worldwide, with major consequences for our ecosystems and without us quite knowing why. A new AI method is set to help monitor and catalog insect biodiversity, which until now has been quite challenging. |
| Scientists engineer bacteria to cope in challenging environments Posted: 22 Feb 2022 10:52 AM PST Researchers have engineered bacteria with internal nutrient reserves that can be accessed when needed to survive extreme environmental conditions. The findings pave the way for more robust biotechnologies based on engineered microbes. |
| New treatment for people with asthma, food allergies? Posted: 22 Feb 2022 10:52 AM PST Researchers have made an important new discovery about how a particular molecule could improve lung function for people with asthma and food allergies. |
| Male birds have stronger immune system than females, research suggests Posted: 22 Feb 2022 10:52 AM PST Scientists studied the differences in activity of immune genes between male and female Kentish Plovers and found that the immune genes of males were more active. This is evidence that males live longer than females due to differences in their immune systems. |
| Pine needles tell the story of PFAS in North Carolina Posted: 22 Feb 2022 10:52 AM PST The humble pine tree is more than just a common sight in North Carolina -- it's also a handy tool for monitoring the proliferation of per- and polyfluoroalkyl substances (PFAS) in our state over time. |
| Frog with tapir-like nose found in Amazon rainforest, thanks to its 'beeping' call Posted: 22 Feb 2022 10:51 AM PST A tiny burrowing frog that lives underground in the Amazon, known to local people as the 'tapir frog' because its long nose, has been given an official scientific description. |
| 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. |
| Chemist targets pesky mosquitoes’ genes Posted: 22 Feb 2022 10:51 AM PST The next generation of mosquito control might target the pests' reproductive genes. Researchers examined genetic material of three species of mosquito responsible for killing millions of people around the world each year. Researchers revealed the surprising genetic modifications female mosquitoes undergo, in part to create the next generation. |
| 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. |
| Connecting science to medicine: Tendon-like tissue created from human stem cells Posted: 22 Feb 2022 09:13 AM PST Tendons connect muscles with bones. When injured, they are really difficult to repair, and the existing therapeutic strategies often have complications. Researchers constructed artificial tendons that were mechanically and biologically similar to normal tendons using human induced pluripotent stem cells. The tendons were successfully implanted in a mouse model of tendon rupture. These findings offer a novel strategy for tendon repair and regeneration. |
| Fish generate movable pairs of vortices to propel them forward like body waves Posted: 22 Feb 2022 09:12 AM PST Researchers show that fish, through precise control of body fluctuations, generate movable vortex pairs of high- and low-pressure regions that enable them to swim. They used particle image velocimetry and high-speed cameras to analyze the spontaneous swimming of zebrafish in a tank, and the findings provide the groundwork in the design of flexible structures for a high-performance underwater bionic propeller. |
| 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. |
