How HIV smuggles its genetic material into the cell nucleus
Each year, about 1 million individuals worldwide become infected with HIV, the virus that causes AIDS. To replicate and spread the infection, the virus must smuggle its genetic material into the cell nucleus and integrate it into a chromosome......»»
New route to quantum spin liquid materials discovered
A new route to materials with complex disordered magnetic properties at the quantum level has been produced by scientists for the first time. The material, based on a framework of ruthenium, fulfills the requirements of the Kitaev quantum spin liquid.....»»
Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»
Picky proteins: Understanding yeast adaptor protein selectivity
The cellular membrane controls the passage of substances in and out of the cell. Some larger cargo, such as membrane proteins, nutrients, and pathogens, enter the cell via a process known as clathrin-mediated endocytosis......»»
Q&A: Holobiont biology, a new concept for exploring how microbiome shapes evolution of visible life
Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new species of animals and plants, according to Seth Bordenstei.....»»
Squishy microgels in granular biomaterials confine and direct cell behavior
A simple biomaterial-based strategy that can influence the behavior of cells could pave the way for more effective medical treatments such as wound healing, cancer therapy and even organ regeneration, according to a research team at Penn State......»»

DNA shows Pompeii’s dead aren’t who we thought they were
Integrating genetic data with historic and archaeological data can enrich or correct popular narratives. People have long been fascinated by the haunting plaster casts of the bodi.....»»
Mitochondrial study offers new insights into how our cells process RNA for energy production
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have made a major discovery in how human cells produce energy. Their study, published in The EMBO Journal, reveals the detailed mechanisms of how mitochondria process.....»»
Netflix now lets you share screenshots of your favorite moments from a movie or show
Pretty much every video streaming platform has DRM-protected content, which aims to prevent users from distributing copyrighted material. Unfortunately, this also means that users can’t easily share screenshots of specific moments of something they.....»»
Researchers discover genetic reason for the red, yellow and orange bills of Australian finches
What gives an Australian finch its brilliantly colored red, yellow or orange bill? A major new study has uncovered the genetic switches controlling these distinctive colors, revealing a key piece in the puzzle of how animals develop their coloration......»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
Probability training: Preventing errors of reasoning in medicine and law
How trustworthy is a positive HIV test result? How probable is an actual infection when the test is positive? Even professionals often get such questions wrong, which can lead to misdiagnoses and unnecessary surgeries......»»
Genetic repair via CRISPR can inadvertently introduce other defects, researchers show
The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain condit.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
Researchers uncover focal adhesions as subcellular signaling hubs in PI3K-AKT pathway
