Past coronavirus infections don’t seem to help with SARS-CoV-2
Neither T nor B cells seem to use memory of one virus to attack the other. Enlarge / False color image of viruses attached to a cell's surface. (credit: NIAID) While the SARS-CoV-2 virus is new to humans, coronaviruses in general aren't. There.....»»
Antimicrobial peptide from cows shows potential for treating hypervirulent bacteria
University of Central Florida College of Medicine researcher Renee Fleeman is on a mission to kill drug-resistant bacteria, and her latest study has identified a therapy that can penetrate the slime that such infections use to protect themselves from.....»»
Researchers discover key functions of therapeutically promising jumbo viruses
Antibiotic medicines became a popular treatment for bacterial infections in the early 20th century and emerged as a transformational tool in human health. Through the middle of the century, novel antibiotics were regularly developed in the medication.....»»
Cats suffer H5N1 brain infections, blindness, death after drinking raw milk
Mammal-to-mammal transmission raises new concerns about the virus's ability to spread. Enlarge / Farm cats drinking from a trough of milk from cows that were just milked. (credit: Getty | ) On March 16, cows on a Texas d.....»»
Experts develop way to harness CRISPR technology to deal with antimicrobial resistance
Antimicrobial resistance (AMR) is continuing to increase globally, with rates of AMR in most pathogens increasing and threatening a future in which every day medical procedures may no longer be possible and infections thought long dealt with could ki.....»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
Engineers muffle invading pathogens with a "molecular mask"
Vaccines remain the gold standard of protection against dangerous pathogens, but take considerable time and vast resources to develop. Rapidly mutating viruses such as SARS-CoV-2 can blunt their effectiveness and even render them obsolete......»»
Lakes worldwide are facing a slew of health issues that may become chronic
Like humans, lakes are living systems that can suffer from a number of health issues, including circulatory and respiratory problems, infections, nutritional imbalances, and heat-related illnesses. Without treatment, these conditions can become chron.....»»
Key protein regulates immune response to viruses in mammal cells
Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and.....»»
Life-threatening rat pee infections reach record levels in NYC
Between 2001 and 2020, there was an average of 3 cases per year. Last year's tally was 24. Enlarge / A rat looks for food while on a subway platform at the Columbus Circle - 59th Street station on May 8, 2023, in New York City......»»
Arboviruses, mosquitoes and potential hosts tracked in real time in São Paulo city
The technology used to sequence SARS-CoV-2 at record speed early in the COVID-19 pandemic has been successfully tested as a technique to monitor arboviruses and diseases transmitted mainly by mosquitoes......»»
Study investigates coronavirus dynamics in bats: Lower biodiversity means more pathogens
The loss of biodiversity poses a challenge for nature and humans alike. A study led by Ulm University shows that a decline in biodiversity promotes the spread of potentially zoonotic pathogens......»»
Researchers resolve old mystery of how phages disarm pathogenic bacteria
Bacterial infections pose significant challenges to agriculture and medicine, especially as cases of antibiotic-resistant bacteria continue to rise. In response, scientists at Texas A&M AgriLife Research are elucidating the ways that bacteria-infecti.....»»
A new coating method in mRNA engineering points the way to advanced therapies
Medicine can help to treat certain illnesses; for example, antibiotics can help overcome infections, but a new, promising field of medicine involves providing our body with the "blueprint" for how to defeat illnesses on its own......»»
How being furloughed affected people"s sense of time and relationship with work
Between March 2020 and September 2021, millions of workers furloughed under the UK government's Coronavirus Job Retention Scheme lived what for many of us is a dream: being paid not to work......»»
Scientists report that buffer and pH strongly affect the phase separation of SARS-CoV-2 N protein
In a new paper published in Molecular Biology of the Cell, the Allain lab (IBC) reported that the phase separation of the SARS-CoV-2 N protein strongly depends on the chosen buffer and pH. For example, the protonation of a single histidine side chain.....»»
Attack and defense in the microverse: How small RNA molecules regulate viral infections of bacteria
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: ani.....»»
Unlocking the secrets of disease resistance in chrysanthemums: A holistic approach to combating black spot disease
Chrysanthemum, celebrated for its ornamental, medicinal, and beverage value, faces significant threats from bacterial and fungal infections, particularly black spot disease caused by Alternaria alternate, which leads to severe economic losses. Curren.....»»
Must mRNA be cloaked in a lipid coat to serve as a vaccine?
The Uchida Laboratory of Innovation Center of NanoMedicine has demonstrated that intradermal administration of mRNA alone (naked mRNA) without protection by nanoparticles induced robust vaccination against SARS CoV-2, a virus causing COVID-19, in mic.....»»
New antibiotic class effective against multidrug-resistant bacteria discovered
Scientists at Uppsala University have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. The new antibiotic class is described in an article i.....»»
Biochemists discover first new antibacterial class in decades
Vanderbilt biochemists are part of a team taking a stride toward the development of antibacterials to treat uncomplicated urinary tract infections, a pervasive bacterial infection that affects 50%–60% of women in their lifetime......»»
