Research into metal-breathing bacteria could pave way for new generation of 'living sensors'

When the Shewanella oneidensis bacterium "breathes" in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices.

Disseminated cancer cells hijack crucial iron micronutrients to survive

In order to survive within the remote and harsh anatomical microenvironments of the central nervous system, the disseminated cancer cells that cause rare yet deadly leptomeningeal metastases (LM) hijack crucial iron micronutrients from native macrophages, researchers report.

Microbiologists identify bacteria which feed on manganese

Caltech microbiologists have discovered bacteria that feed on manganese and use the metal as their source of calories. Such microbes were predicted to exist over a century ago, but none had been found or described until now.

Combination of western-style high-fat diet with antibiotic can increase the risk of pre-IBD

Researchers have found that combining a Western-style high-fat diet with antibiotic use significantly increases the risk of developing pre- inflammatory bowel disease.

Viral load peaks in early stages of COVID-19, study shows

In a retrospective study, investigators from New York University Langone Health found that the quantity of SARS-CoV-2 (viral load) collected from patients in the emergency department is significantly higher in patients with fewer or milder symptoms who did not require hospitalization--the opposite of what might be expected.

New link found between impaired brain energy metabolism and delirium

Scientists from Trinity College Dublin have discovered a new link between impaired brain energy metabolism and delirium - a disorienting and distressing disorder particularly common in the elderly and one that is currently occurring in a large proportion of patients hospitalized with COVID-19.

Keck Medicine of USC participates in clinical trial to test antiviral drug as potential COVID-19 treatment

Keck Medicine of USC physicians are enrolling patients as part of an international clinical trial to evaluate the safety and efficacy of an antiviral drug, DAS181, as a possible treatment for hospitalized patients with severe COVID-19.

New radiotracer provides a quantitative measure of disease progression after stroke

A new radiotracer, 18F-SynVesT-2, can directly assess synaptic density changes in the brain, providing an objective and quantitative measure of disease progression after stroke.

Researchers to develop new ways to prevent esophageal cancer

The incidence of esophageal adenocarcinoma has increased 8-fold over the past 50 years. This is one of the deadliest cancers, with a five-year survival rate of only 20 percent.

New technology generates immune response by delivering antigens to APCs in the spleen

Red blood cells do more than shuttle oxygen from our lungs to our organs: they also help the body fight off infections by capturing pathogens on their surfaces, neutralizing them, and presenting them to immune cells in the spleen and liver.

Harvard neurobiologists provide new insights into the mystery of scent

The premiere of the movie Scent of Mystery in 1960 marked a singular event in the annals of cinema: the first, and last, motion picture debut "in glorious Smell-O-Vision."

Flame sterilization of shake-flasks affects cell culture

Researchers commonly culture bacteria for many purposes, such as to screen pharmaceuticals and manufacture vaccines. In these cases, shake flasks have been commonly and generally used for over 90 years to cultivate microbes.

Study shows how inflammatory changes in tumors cause drug resistance in blood vessels

Scientists at Hokkaido University and collaborators have identified how inflammatory changes in tumors caused by chemotherapy trigger blood vessel anomalies and thus drug-resistance, resulting in the poor prognosis of cancer patients.

COVID-19 virus can infect heart cells in a lab dish, study shows

A new study shows that SARS-CoV-2, the virus that causes COVID-19 (coronavirus), can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be directly infected by the virus.
