Scientists took 10 years to figure out how one type of superbug gains its ability to infect diverse bacterial species. When prompted, Google's new AI "co-scientist" gave them the answer in two days.

Gilead said the FDA is reviewing its experimental, twice-yearly injectable drug designed to prevent HIV

Norovirus, sometimes called the "winter vomiting disease" or "two-bucket disease" — because it causes both vomiting and diarrhea — is on the rise across the nation, even as seasonal flu is taking off and walking pneumonia rages on.

MIS-C, a rare post-COVID inflammatory syndrome in children, may be triggered when the immune system mistakes its own proteins for those of the virus.

The twice-yearly injectable preexposure prophylaxis demonstrated 100% efficacy at interim results. Now, specialists are sharing what they are looking forward to seeing at AIDS 2024 in Munich.

Only 'traces' of spike-specific salivary antibodies found in vaccinated SARS-CoV-2-naive people

Important signaling molecules called phospholipids are active throughout cells in small compartments called condensates, rather than functioning primarily in cell membranes as previously thought, according to a study from researchers at Weill Cornell Medicine. The finding helps open a new avenue of investigation in cell biology and may also be relevant to the study of neurodegenerative diseases such as amyotrophic…

And a look at the bigger picture behind the frozen-food outbreaks

Mammalian seminal fluid contains a variety of proteins secreted by the accessory sex glands that are important for the processes involved in fertilization. One of these proteins, which is found in ungulates—and in particularly large quantities in boars—is the spermadhesin AQN-3.

Scientists from The Federal Research Centre "Fundamentals of Biotechnology" of the Russian Academy of Sciences, together with foreign colleagues, have demonstrated that human 14-3-3 proteins, which are known for their role in replication of many viruses, bind differentially with more often mutating regulatory parts of nucleoproteins (N protein) of the SARS-CoV-2 virus.

An international team of oceanologists, chemists and microbiologists has announced the discovery of several new viruses that infect plankton in all of the world's oceans. In their paper published in the journal Nature, the group describes how they found evidence of the viruses from water samples collected during the Tara Ocean expedition and what they have learned about them thus far.

Here the authors describe a small antibody-like protein that can prevent infection by diverse SARS-CoV-2 variants in cell culture and in mice that were intranasally treated with this inhibitor before or shortly after being exposed to the virus.

The so-called winter vomiting disease has been closing schools and hitting long-term care facilities this year. Here's what you should know

At-home rapid tests have become a staple of COVID-19 precautions, but some experts worry that people are relying too much on these tests and that's creating a false sense of security.

(Reuters) -The U.S. Food and Drug Administration (FDA) on Thursday approved Gilead Sciences Inc's Sunlenca therapy for HIV infections, paving the way for a...

In this free webinar, learn about which conditions are at risk of impacting adeno-associated virus (AAV) capsid stability and aggregation. Attendees will understand the multiple pathways where AAVs can lose their structure and their payload. The featured speaker will discuss ways to streamline stability testing of AAVs in long term storage and freeze-thaw cycles.

New evidence in the scientific community indicates that there is a strong correlation between COVID-19, its related vaccines, ...

Vikas Nanda has spent more than two decades studying the intricacies of proteins, the highly complex substances present in all living organisms. The Rutgers scientist has long contemplated how the unique patterns of amino acids that comprise proteins determine whether they become anything from hemoglobin to collagen, as well as the subsequent, mysterious step of self-assembly where only certain proteins clump…

BELLVILLE, South Africa, Oct 04 (IPS) - It's hard to imagine a time when "coronavirus" wasn't a household word. But for a long time, this family of viruses had merited very little attention. Believed to be ubiquitous among animals and avian species, the first coronavirus to infect and cause disease in humans was only isolated and identified in the 1960s.
