Published Team designs molecule to disrupt SARS-CoV-2 infection
(via sciencedaily.com) A team of scientists designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.
Published Some coastal salt marshes are keeping up with sea level rise -- for now
(via sciencedaily.com) The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.
Published Human body a breeding ground for antimicrobial resistance genes
(via sciencedaily.com) The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research.
Published Beneficial bacteria in the infant gut uses nitrogen from breast milk to support baby's health
(via sciencedaily.com) A nutrition scientist who has spent his career studying breast milk has demonstrated how beneficial microbes in the gut of infants use nitrogen from human milk to support pediatric nutrition and development.
Published HIV genomes that hide in white blood cells offer new target to eliminate infections
(via sciencedaily.com) To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code. Now, in a study using blood samples from men and women with HIV on long-term suppressive therapy, a team of scientists reports new evidence that one such stable reservoir of HIV genomes can be found in circulating white blood cells called monocytes.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published Researchers find clue to help plants grow with low phosphorus levels
(via sciencedaily.com) Phosphorus is a natural mineral found in fertilizer that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
Published Pathogen mapped: Evolution and potential treatments
(via sciencedaily.com) A parasite which has devastating impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells -- providing clues to their function and helping to identify potential drug targets.
Published RNA vaccination in rabbit mothers confers benefits to offspring in the womb
(via sciencedaily.com) Newly developed mRNA vaccines against Zika virus and HIV-1 produced strong antibody responses that transferred from pregnant rabbits to their offspring, researchers report. As noted by the authors, the results support further development of their vaccine platform, LIONTM/repRNA, for maternal and neonatal settings to protect against mother-to-child transmission of pathogens in animals and humans.
Published A readily available dietary supplement may reverse organ damage caused by HIV and antiretroviral therapy
(via sciencedaily.com) MitoQ, a mitochondrial antioxidant that is available to the public as a diet supplement, was found in a mouse study to reverse the detrimental effects that HIV and antiretroviral therapy (ART) have on mitochondria in the brain, heart, aorta, lungs, kidney and liver.
Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
Published Deceptive daisy's ability to create fake flies explained
(via sciencedaily.com) Researchers have discovered how a South African daisy makes fake lady flies on its petals to trick male flies into pollinating it.
Published As the worm turns: New twists in behavioral association theories
(via sciencedaily.com) Physicists have developed a dynamical model of animal behavior that may explain some mysteries surrounding associative learning going back to Pavlov's dogs.
Published Harnessing power of immune system may lessen reliance on antibiotics for infections like TB
(via sciencedaily.com) Researchers have found that the body's process of removing old and damaged cell parts, is also an essential part of tackling infections that take hold within our cells, like TB. If this natural process can be harnessed with new treatments, it could present an alternative to, or improve use of antibiotics, especially where bacteria have become resistant to existing drugs.
Published Researchers discover a way to fight the aging process and cancer development
(via sciencedaily.com) Damage in the human genome can be repaired. But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Scientists warn of rise in potentially fatal bacterial infection due to global warming
(via sciencedaily.com) Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States. Vibrio vulnificus bacteria grow in warm shallow coastal waters and can infect a cut or insect bite during contact with seawater. The researchers predict that by 2041--2060 infections may spread to encompass major population centers around New York. Combined with a growing and increasingly elderly population, who are more susceptible to infection, annual case numbers could double.
Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published Known active ingredient as new drug candidate against mpox
(via sciencedaily.com) Mpox -- previously known as 'monkeypox' -- is currently spreading worldwide. Researchers have now identified a compound that could help fight the disease.
Published Memory B cell marker predicts long-lived antibody response to flu vaccine
(via sciencedaily.com) Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.
