A study published today examines the evolutionary and epidemiologic history of an epidemic strain of extensively drug-resistant tuberculosis (XDR-TB) -- called LAM4/KZN. This strain was first reported in a 2005 outbreak ...

Spending an hour in talk therapy with a trained counselor costs much more, and takes more time, than swallowing an inexpensive antidepressant pill. But for people with a new diagnosis of major depression, the costs and b...

An international team has discovered a cheap and efficient way to identify transmission hotspots for schistosomiasis. The research uses rigorous field sampling and aerial images to precisely map communities that are at g...

Stiff collagen and stretchy elastin fibers packed together in rows allow the respiratory system to stretch and snap back into shape. Scientists previously thought these fibers govern the mechanics of the airways due to t...

A new study shows how a parent's use of marijuana, past or present, can influence their child's substance use and well-being.

Widespread adaptation of healthier diets would markedly reduce the environmental impact of agriculture and food production. For the first time, researchers have tied the health impacts of foods to their overall environme...

Chemists match models and experiments to see how salt modifies surface interactions in chromatography used to separate valuable drug proteins. The research could be a step toward simplifying drug manufacture.

A sweeping study looking at an extensive collection of data -- involving more than a million offenders at 30 different Canadian and US research sites -- found that while fewer people were being locked up, crime rates sho...

Between 2005 and 2015, as the opioid crisis in America came into focus, prescriptions for gabapentinoid medications -- gabapentin and pregabalin -- to adults with cancer saw a two-fold increase, a new study has found.

As if you didn't already have enough to worry about to keep you up at night, a new study indicates that poor sleep can negatively affect your gut microbiome, which can, in turn, lead to additional health issues.

The largest randomized trial in asymptomatic patients with smoldering multiple myeloma suggests that lenalidomide, a cancer drug, may delay the onset of bone and other myeloma-related organ damage.

A new bioinformatics tool, MHcut reveals that a natural repair system for DNA damage, microhomology-mediated end joining, is probably far more common in humans than originally assumed. Using MHcut and commercial genome-e...

Many policymakers and scholars believe offering paid leave to families would be a game changer for US moms and families, leading to increased equity in labor markets and helping eliminate the 'mommy gap' in pay.

Researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects in certain proteins ...

New research suggests that eating one avocado a day may help keep 'bad cholesterol' at bay. According to the researchers, bad cholesterol can refer to both oxidized low-density lipoprotein (LDL) and small, dense LDL part...

Finding a handful of cancer cells hiding among billions of blood cells in a patient sample can be like finding a needle in a haystack. In a new approach enabled by 3D-printed cell traps, researchers are removing the hay ...

Drugs can be safely delivered to cancerous lymph nodes via the lymphatic system and then released inside the nodes using sound waves. Researchers tested the treatment on mice with metastatic breast cancer.

A new study has found that sugar-sweetened acidic drinks, such as soft drinks, is the common factor between obesity and tooth wear among adults.

Nonnutritive or artificial sweeteners are a growing part of US diets, now consumed by at least one in four children. A new American Academy of Pediatrics policy statement offers a summary of the existing data around nonn...

Working with model mice, post-mortem human brains, and people with schizophrenia, researchers have discovered that a subtype of schizophrenia is related to abnormally high levels hydrogen sulfide in the brain. Experiment...
