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 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 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.
Published Proof-of-concept study to find functional cure for HIV
(via sciencedaily.com) Original source Researchers conducted a breakthrough proof-of-concept study that found an HIV-like virus particle that could cease the need for lifelong medications.
Published The ocean is becoming too loud for oysters, research finds
(via sciencedaily.com) Original source Baby oysters rely on natural acoustic cues to settle in specific environments, but new research reveals that noise from human activity is interfering with this critical process.
Published Researchers record images and data of a shark experiencing a boat strike
(via sciencedaily.com) Original source Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.
Published Mixed approach to reforestation better than planting or regeneration alone
(via sciencedaily.com) Original source Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.
Published Virtual reality training for physicians aims to heal disparities in Black maternal health care
(via sciencedaily.com) Original source A virtual reality training series being developed for medical students and physicians teaches them about implicit bias in their communications with their patients who are people of color and how that affects race-based health care disparities.
Published Fish adjust reproduction in response to predators
(via sciencedaily.com) Original source Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.
