Researchers unveil complete neuronal map of fruit fly brain

Researchers map the whole brain of Drosophila melanogaster, or the fruit fly, which comprises about 140,000 neurons and over 50 million synapses.

Cancer Research UK backs study to develop preventive ovarian cancer vaccine

In this study, the Cancer Research UK-funded scientists will establish the targets for the vaccine. They will find out which proteins on the surface of early-stage ovarian cancer cells are most strongly recognized by the immune system and how effectively the vaccine kills mini-models of ovarian cancer called organoids.

KiNet web portal enhances study of kinase functions in cellular signaling pathways

Researchers from the Icahn School of Medicine at Mount Sinai have introduced KiNet, an interactive web portal designed to explore kinase-substrate interactions in human cellular systems. These interactions play a vital role in modulating complex signaling pathways that control various cellular processes, such as cell growth, differentiation, and response to environmental stimuli.

Understanding the brain’s process of dividing experiences into events

The moment a person steps off the street and into a restaurant - to take just one example - the brain mentally starts a new "chapter" of the day, a change that causes a big shift in brain activity. Shifts like this happen all day long, as people encounter new environments, like going out for lunch, attending their kid's soccer game, or settling in for a night of watching TV.

Stem cell transplants show promise for macular hole repair in monkeys

Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report October 3rd in the journal Stem Cell Reports. After transplantation, the macular holes were closed by continuous filling of the space with retinal tissue.

Unlocking the mystery of the fruit fly's internal compass

For decades, researchers had a theory about how an animal's brain keeps track of where it is relative to its surroundings without outside cues – like how we know where we are, even with our eyes closed

Dietary zinc may reduce plasmid transfer in gut microbes

Genes responsible for antimicrobial resistance (AMR) can spread from microbe to microbe through circular genetic material called plasmids, and this lateral transfer occurs in the gut.

Houston Methodist researchers join national consortium to develop herpesvirus vaccine

Houston Methodist researchers will be part of a national consortium funded by an up to $49 million award from the U.S. Government's Advanced Research Projects Agency for Health (ARPA-H) to develop a vaccine against two of the most common and destructive strains of herpesviruses that latently infect a majority of Americans and can lead to acute infections, multiple forms of cancer, autoimmune disease and birth defects.

Quantum discovery shows potential to revolutionize pharmaceutical development

University of Copenhagen mathematicians have developed a recipe for upgrading quantum computers to simulate complex quantum systems, such as molecules.

Insights into bacterial coexistence in fungal cells

An organism as a tenant in another - in biology, this often works quite well. ETH researchers have now shed light on how such a partnership of a cell in a cell can establish.

New pathway linking neuron selectivity to cognitive disorders uncovered

Neuroscientists from Johns Hopkins Medicine say they have determined how a brain cell surface molecule shapes the way certain neurons behave.

Key RNA pathway controlling DNA packaging and cancer progression

Inside every cell, inside every nucleus, your continued existence depends on an incredibly complicated dance. Proteins are constantly wrapping and unwrapping DNA, and even minor missteps can lead to cancer.

Fruit fly brain connectome offers critical clues for understanding brain function and behavior

A scientific team supported by the National Institutes of Health (NIH) unveiled the first complete map of the neural connections of the common fruit fly brain. The map provides a wiring diagram, known as a connectome, and is the largest and most complete connectome of an adult animal ever created.

Study uncovers how listeria monocytogenes survives in nutrient-poor environments

The detection tests commonly used to check for the absence of microbes in hospitals or the agri-food industry are based on microbial growth, i.e. the laboratory cultivation of microorganisms from a sample to be checked.

Scientists overcome major challenge in gene therapy and drug delivery

Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells. They created an array of nanopillars that can breach the nucleus of a cell - the compartment that houses our DNA - without damaging the cell's outer membrane.

Study highlights the role of genetic factors in COVID-19 thrombosis and inflammation

Despite global vaccination efforts, COVID-19 continues to pose significant risks, leading to severe complications and fatalities. These risks are driven by disrupted coagulation, impaired fibrinolysis, which is the process of breaking blood clots, and heightened inflammatory responses.

New insights into the link between respiratory infections and chronic lung diseases

A 3D reconstruction of a mouse lung four days after infection with fluorescent Sendai virus reveals widespread virus presence (red) and active replication (green).

Researchers develop technology to change protein identity in vivo

Researchers at the RIKEN Cluster for Pioneering Research (CPR) have developed technology that can alter, within the body, the recognized identity of proteins. The innovation, published in Nature Communications on October 2, allowed researchers to target mouse tumors with a protein and then transport that protein out of the body.
