Bacteria Found Living in Snake and Spider Venoms
Contrary to what is commonly believed, the venom of snakes and spiders is actually populated with microbes, including bacteria that could cause infection in people who have suffered a bite, a recent study shows.
Synthetic Antibiotic Neutralizes Drug-Resistant Bacteria in Mice
A new antibiotic, synthesized at The Rockefeller University and derived from computer models of bacterial gene products, appears to neutralize even drug-resistant bacteria.
Gene Finding Links Vascular Disease to Alzheimer's
A study has found that changes in the activity of a gene called FMNL2 caused by cerebrovascular disease, prevent the efficient clearance of toxic proteins from the brain, leading to Alzheimer’s disease.
Nanoparticles for Broader and Safer SARS-CoV-2 Vaccines
A nanoparticle vaccine that combines the spike protein and its stem subunit promotes a broader immune response that is sustained for at least four months, a new study shows.
Tumor "Mutational Signatures" Predict Treatment Response
Researchers have found that so-called “mutational signatures” – that reflect a collection of mutations found across the entire genome of a tumor – can predict the activity of various drugs applied to cancer cells from several tumor types.
Sound Exposure in the Womb Shapes the Auditory System
A new study suggests that the low-frequency sounds fetuses can hear are possibly necessary for auditory development.
Sugary Protein May Be Gumming Up Brain Cleaning in Alzheimer's Disease
In a bit of “reverse engineering” research using brain tissues from five people who died with Alzheimer’s disease, researchers say they discovered that a special sugar molecule could play a key role in the development of Alzheimer’s disease.
HIV Drug Could Enhance How the Brain Links Memories
Increased expression of the CCR5 gene in the brain is associated with poor memory linking, but the drug used to treat HIV infection has been shown to suppress CCR5 and improve memory linking in older mice.
New Theory Looks at How Biodiversity Affects Interspecies Interaction
The term biodiversity invites images of lush rainforests, dynamic estuaries, and other biomes where a kaleidoscope of species interact within their communities. Now a new study has proposed a theory of how biodiversity affects the amount of interspecies interaction in a community.
Study Will Research Third Dose Booster Options for 12-to-15-Year-Olds
Researchers running the Com-COV program have launched a further study of COVID-19 vaccination schedules in young people aged 12 to 15.
New Type of Extremely Reactive Substance Found in the Atmosphere
Researchers have documented the formation of so-called trioxides, an extremely oxidizing chemical compound that likely affects human health and global climate, for the first time under atmospheric conditions.
