From single-celled organisms like bacteria to complex multicellular organisms like humans, … Read more

How early cells harvested hydrogen energy

Hydrogen gas is a clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is a good fuel for as … Read more

Researchers develop modified compound with potent anti-HIV activity

A team of University of Michigan researchers has successfully modified a naturally occurring chemical compound in the lab, resulting in advanced lead compounds with anti-HIV activity. Their results, published in the Journal of Medicinal Chemistry, offer a new path forward in the development of drugs that could potentially help cure—rather than treat—HIV. Although effective treatments are available to … Read more

Study links persistent UTI pain to nerve cell overgrowth in bladder

A perplexing problem for people with recurring urinary tract infections (UTIs) is persistent pain, even after antibiotics have successfully cleared the bacteria. Now Duke Health researchers have identified the likely cause—an overgrowth of nerve cells in the bladder. The finding, appearing March 1 in the journal Science Immunology, provides a potential new approach to managing … Read more

New study suggests potential to shorten treatment duration for drug-resistant TB

Patients who have drug-resistant tuberculosis (TB) have a similar microbiological response to bedaquiline-based second-line medications as patients with drug-sensitive TB taking first-line regimens, according to researchers at Weill Cornell Medicine in New York and GHESKIO Centers in Haiti. Second-line medications are those that are given when one or more of the drugs given first for … Read more

Researchers unveil essential proteins for efficient nitrogenase function

Nitrogenases are considered promising candidates for the sustainable enzymatic production of ammonia and carbon compounds. Unfortunately, one bottleneck in this complex process, the supply of electrons to the enzymes, has remained a mystery until now. A team at the Max Planck Institute for Terrestrial Microbiology in Marburg has discovered two essential electron carriers that play … Read more

New protein identified as crucial for safe sex chromosome pairing in sperm development

Early in the development of sperm, a strange event happens: the X and Y chromosomes condense into tight packages and are sequestered away from the other 44 human chromosomes. If any part of this process goes awry, the cells cannot mature into sperm. Researchers in the UC Davis College of Biological Sciences have now identified … Read more

Scientists develop antibody to neutralize deadly snake venoms

Scientists at Scripps Research have engineered a groundbreaking antibody capable of neutralizing the lethal effects of venomous snake toxins from a diverse range of species across Africa, Asia, and Australia. This antibody, detailed in Science Translational Medicine, demonstrated its efficacy in protecting mice from the venom of notoriously deadly snakes such as black mambas and … Read more

New protein target identified for aggressive pancreatic cancer

Pancreatic cancer is the No. 3 cause of cancer-related deaths in the United States, and only 12% of patients survive five years after being diagnosed. Severe pancreatic cancer is associated with metastasis, and it is this spread of secondary tumors that usually causes death, but little is known about the molecular mechanisms that drive metastasis. … Read more

COVID-19’s lasting impact on brain revealed

A groundbreaking study spearheaded by the University of Liverpool and King’s College London has unveiled unsettling revelations about the lasting impacts of COVID-19 on the brain. Despite the absence of abnormal inflammation markers in routine blood tests, the research indicates persistent markers of brain injury in individuals months after their COVID-19 infection has subsided. This … Read more

Simultaneous production of biofuel and valuable pigments from plant fiber

We often look to the smallest lifeforms for help solving the biggest problems: Microbes help make foods and beverages, cure diseases, treat waste and even clean up pollution. Yeast and bacteria can also convert plant sugars into biofuels and chemicals traditionally derived from fossil fuels—a key component of most plans to slow climate change. Now … Read more
