Published Deadly virus structures point toward new avenues for vaccine design
(via sciencedaily.com) Original source By comparing the structures of protein complexes from different lineages of the dangerous Lassa virus, a team identified new antibodies and vaccine targets.
Published How tasty is the food?
(via sciencedaily.com) Original source A hormone and specialized brain cells regulate feeding behavior in mice.
Published Failed antibiotic now a game changing weed killer for farmers
(via sciencedaily.com) Original source Weed killers of the future could soon be based on failed antibiotics. Researchers have found a molecule which was initially developed to treat tuberculosis but failed to progress out of the lab as an antibiotic is now showing promise as a powerful foe for weeds that invade our gardens and cost farmers billions of dollars each year.
Published Study shows key role for human T cells in the control of Respiratory Syncytial Virus (RSV) infection
(via sciencedaily.com) Original source A new study has shown that human T cells have an important role to play in controlling infection.
Published A look into the heart of cellular waste disposal
(via sciencedaily.com) Original source Researchers reveal how a nanomachine takes care of cleaning up inside the cell.
Published Scientists from the Global South innovate to track ongoing amphibian pandemic
(via sciencedaily.com) Original source Scientists have developed and validated an assay that could be used to diagnose Indian strains of the amphibian chytrid fungus that were not detected by previous tests. The novel assay also works for other better-known strains from other parts of the world, such as the one present in Panama.
Published Engineers create bacteria that can synthesize an unnatural amino acid
(via sciencedaily.com) Original source Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The researchers also taught a single bacterial strain to create the amino acid and place it at specific sites within target proteins. These findings provide a foundation for developing unique vaccines and immunotherapies in the future.
Published Previous smallpox vaccine provides immunity to mpox
(via sciencedaily.com) Original source Vaccines against smallpox given until the mid-1970s offer continuing cross-reactive immunity to mpox (previously known as monkeypox), researchers report.
Published What you count is not necessarily what counts
(via sciencedaily.com) Original source Seawater is full of bacteria, hundreds of thousands live in every liter. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate.
Published A multiomics approach provides insights into flu severity
(via sciencedaily.com) Original source Researchers were able to identify changes in the accessibility (that is, the 'readability') of transposable elements. To do this, the researchers used an approach combining various sets of multiomics data, which characterize and quantify collections of biomolecules in cells or organisms. One was the transcriptome, which consists of all copies of RNA transcribed from DNA in the cell. The other was the epigenome, which is the collection of chemical changes to DNA that modify gene expression. An advantage of this multiomics approach is that they were able to identify families of transposable elements with changes in accessibility, which would have likely been missed by previous approaches.
Published New insights into the complex neurochemistry of ants
(via sciencedaily.com) Original source Ants' brains are amazingly sophisticated organs that enable them to coordinate complex behavior patterns such as the organization of colonies. Now, researchers have developed a method that allows them to study ants' brain chemistry and gain insights into the insects' neurobiological processes. The findings could help to explain the evolution of social behavior in the animal kingdom, and shed light on the biochemistry of certain hormone systems that have developed similarly in both ants and humans.
Published Dinosaurs were the first to take the perspectives of others
(via sciencedaily.com) Original source Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction.
Published Under control to the very end -- how our cells kill themselves
(via sciencedaily.com) Original source Every day, millions of cells die in our body. Other than generally assumed, cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture. Researchers have now been able to elucidate the exact mechanism at the atomic level.
Published Microorganisms' climate adaptation can slow down global warming
(via sciencedaily.com) Original source A new study shows that the ability of microorganisms to adapt to climate warming will slow down global warming by storing carbon in soil.
Published A guide through the genome
(via sciencedaily.com) Original source Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation.
Published Earliest evidence of wine consumption in the Americas found in Caribbean
(via sciencedaily.com) Original source Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artefacts recovered from a small Caribbean island.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com) Original source Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published Puppeteer fungus' targeted takeover of 'zombie' flies
(via sciencedaily.com) Original source Researchers reveal the molecular and cellular underpinnings behind the parasitic fungus, Entomophthora muscae's (E. muscae), ability to manipulate the behavior of fruit flies.
Published Synthetic biology: proteins set vesicles in motion
(via sciencedaily.com) Original source Biophysicists have designed a new cell-like transport system that represents an important milestone on the road to artificial cells.
Published Humanity's earliest recorded kiss occurred in Mesopotamia 4,500 years ago
(via sciencedaily.com) Original source Written sources from Mesopotamia suggest that kissing in relation to sex was practiced by the peoples of the ancient Middle East 4,500 years ago.
