NewsReinfections from the virus that causes COVID-19 likely have similar severity to original infection
Researchers have found that severe infections from the virus that causes COVID-19 tend to foreshadow similar severity of infection the next time a person contracts the disease.

NewsNanoparticle vaccines enhance cross-protection against influenza viruses
To offer cross-protection against diverse influenza virus variants, nanoparticle vaccines can produce pivotal cellular and mucosal immune responses that enhance vaccine efficacy and broaden protection, a new study reveals.

NewsStudy reveals next steps to uncover early life on Earth
Despite decades of research, there’s still much scholars don’t understand about life’s beginnings and early evolution. A UC Riverside paper has opened the door to understanding more and to framing future studies that could help predict climate change and search for life beyond Earth. Source: Tim ...

NewsMagnetic bacteria could be key to the miraculous mystery of migration
The remarkable ability of migratory animals to navigate and recall routes may be attributed to a sensitivity to not just Earth’s magnetic fields, but perhaps an interaction with magnetic bacteria living inside them, a new study suggests.

NewsStudy reveals environmental impact of artificial sweeteners on water microbes
A new study demonstrates how sucralose affects the behavior of cyanobacteria — an aquatic photosynthetic bacteria — and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.

NewsResearchers use microbes to create biodegradable bioplastics from food waste
Researchers are developing biodegradable bioplastics from food waste to give those materials a new – and useful – life.

NewsGut microbe could hold a key to help people benefit from healthy foods
In a study involving 50,000+ individuals from around the world, higher gut levels of Blastocystis, a single-celled organism commonly found in the digestive system, were linked to more favorable indicators of health.

NewsRaw milk is risky, but airborne transmission of H5N1 from cow’s milk is inefficient in mammals
New research suggests that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.

NewsNew bio-based tool quickly detects concerning coronavirus variants
Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.

NewsStudy backs RSV vaccine safety during pregnancy
Vaccinating mothers against respiratory syncytial virus (RSV) during late pregnancy to protect their newborns is not associated with an increased risk of preterm birth or other poor outcomes, according to a new study.

NewsStudy reveals a way to protect microbes from extreme conditions
By helping microbes withstand industrial processing, the method could make it easier to harness the benefits of microorganisms used as medicines and in agriculture.

NewsUncovering ‘Blockbuster T cells’ in the gut wins major prize
Kazuki Nagashima developed a method with which to zero in on individual gut bacterium’s impacts on T cells. His work showed that – contrary to what has been thought – some T cells in the gut can interact with multiple bacteria.

NewsFrom ‘hit to vial’: Discovery and optimization of a promising vaccine adjuvant
Scientists identified a new and promising adjuvant, dubbed PVP-037 - in principle, this compound can be added to any vaccine to enhance its action.

NewsCancer drug could be repurposed to fight Covid-19
Twelve years ago, cancer researchers identified a molecule that helps cancer cells survive by shuttling damaging inflammatory cells into tumor tissue. In new research, they show that the same molecule does the same thing in lung tissue infected with COVID-19.

NewsPasteurization inactivates highly infectious avian flu in milk
Researchers tested nearly 300 milk products from 132 processors in the US and found no infectious H5N1 virus in the samples.

NewsPublic fails to appreciate risk of consuming raw milk, survey finds
Fewer than half of U.S. adults know that drinking raw milk is less safe than drinking pasteurized milk and many Americans do not understand the risks of consuming raw milk, according to a new health survey.

NewsGiant clams - and their algae - may hold the answers to making solar energy more efficient
Researchers present an analytical model for determining the maximum efficiency of photosynthetic systems based on the geometry, movement, and light-scattering characteristics of giant clams.

NewsRegular vaccine boosts may help people who are immunocompromised fight Covid-19
New research finds booster doses of bivalent vaccines given every three to six months helps maintain a person’s ability to neutralize multiple SARS-CoV-2 strains, including XBB.1.5.

NewsStudy illuminates cues algae use to ‘listen’ to their environment
Plants have long been known to release chemicals to respond to stress and relay information to their neighbors. A team of scientists from Bigelow Laboratory have shown that glaucophytes, a small group of single-celled algae distantly related to plants, appear to have the same penchant for chemical communication. This suggests ...

NewsNew lab test to detect persistent HIV strains in Africa may aid search for cure
A multinational team has developed a test that will help measure the persistence of HIV in people affected by viral strains found predominantly in Africa—a vital tool in the search for an HIV cure that will benefit patients around the world.
