Published Researchers decipher new molecular mechanisms related to biological tissue regeneration
(via sciencedaily.com) Original source A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.
Published Faster, cleaner way to extract lithium from battery waste
(via sciencedaily.com) Original source Researchers uncover a rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent.
Published Virus that causes COVID-19 is widespread in wildlife, scientists find
(via sciencedaily.com) Original source SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to new research. The virus was detected in six common backyard species, and antibodies indicating prior exposure to the virus were found in five species, with rates of exposure ranging from 40 to 60 percent depending on the species.
Published Scientists work to build 'wind-up' sensors
(via sciencedaily.com) Original source An international team of scientists has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors.
Published New understanding of fly behavior has potential application in robotics, public safety
(via sciencedaily.com) Original source Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response: they are responding in context-appropriate manner. This knowledge potentially could be applied to train more sophisticated algorithms for scent-detecting drones to find the source of chemical leaks.
Published Lampreys possess a 'jaw-dropping' evolutionary origin
(via sciencedaily.com) Original source Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
Published New drug shows promise in clearing HIV from brain
(via sciencedaily.com) Original source An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment.
Published New battery-free technology to power electronic devices using ambient radiofrequency signals
(via sciencedaily.com) Original source Researchers demonstrated a novel technique to efficiently convert ambient low-power radiofrequency signals into DC power. This 'rectifier' technology can be easily integrated into energy harvesting modules to power electronic devices and sensors, enabling battery-free operation.
Published Ancient marine animal had inventive past despite being represented by few species
(via sciencedaily.com) Original source Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
Published Exploring consciousness with eureka moments
(via sciencedaily.com) Original source We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research of consciousness.
Published Size doesn't matter for mammals with more complex brains
(via sciencedaily.com) Original source Mammals that have evolved more developed brains tend to have a smaller size difference between males and females of that species, according to new research.
Published Scientists identify key protein behind spread of shingles virus
(via sciencedaily.com) Original source Scientists have discovered a new evasion strategy used by the varicella zoster virus, which causes chickenpox and shingles, that may allow it to affect tissues far from the original site of infection.
Published In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment
(via sciencedaily.com) Original source Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The investigators also identified specific strains of bacteria associated with better or worse responses to FMT and immune checkpoint drugs.
Published How a bacterium supports healing of chronic diabetic wounds
(via sciencedaily.com) Original source New research shows that a certain bug, Alcaligenes faecalis (A. faecalis), can facilitate healing of hard-to-treat wounds among people with diabetes. While there are many studies done on potentially harmful bacteria in wounds, the researchers discovered that A. faecalis, a bacterium found in many types of chronic wounds, actually boosts healing of diabetic wounds. The researchers found that the beneficial bacterium can promote skin cell movements that are essential for wound closure by inhibiting enzymes that are over-produced in people with diabetes.
Published How evolution tamed a deadly virus and why we should still worry
(via sciencedaily.com) Original source Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death. The findings offer important lessons in virology that may help guide better preparedness for future outbreaks of other viral diseases.
Published Researchers develop innovative battery recycling method
(via sciencedaily.com) Original source A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published It's got praying mantis eyes
(via sciencedaily.com) Original source The praying mantis is one of the few insects with compound eyes and the ability to perceive 3D space. Engineers are replicating their visual systems to make machines see better.
Published New groups of methane-producing organisms in Yellowstone
(via sciencedaily.com) Original source The team verified that microbes found in Yellowstone National Park hot springs produce methane to grow.
Published Daily rhythms depend on receptor density in biological clock
(via sciencedaily.com) Original source Tweaking the numbers of receptors in a key brain area changes the daily rhythms of rest and wake in mice.
Published Researchers are closing in on a mouse model for late-onset Alzheimer's
(via sciencedaily.com) Original source Researchers are working to create the first strain of mice that's genetically susceptible to late-onset Alzheimer's, with potentially transformative implications for dementia research.
