Science tells us that a lot of good things happen in our brains while we sleep -- learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immu...

Chronic stress during pregnancy triggers an immune response in the brain that has potential to alter brain functions in ways that could contribute to postpartum depression, new research in animals suggests.

Families dealing with the stress and frustration of their child's overly picky eating habits may have a new addition to their parental toolbox. Pediatric researchers recently described a brief group cognitive-behavioral ...

A research team has created a third approach to engineering proteins that uses deep learning to distill the fundamental features of proteins directly from their amino acid sequence without the need for additional informa...

French investigators have described development of resistance to one of the last resort therapies used to treat extremely drug-resistant Pseudomonas aeruginosa. That resistance arose in a single patient over a scant 22 d...

Scientists demonstrate a new approach in fluorescence microscopy that can be used to locate individual biomolecules in 3D space with nanometer-scale precision.

A team has developed a new CRISPR genome-editing approach by combining two of the most important proteins in molecular biology -- CRISPR-Cas9 and a reverse transcriptase -- into a single machine.

New research presents the first demonstration of a specific difference in sperm function associated with sex ratio skewing.

A study has revealed a protein's role in helping bacteria 'reel in' DNA from their environment to acquire new traits, such as antibiotic resistance.

The part of the brain that selectively degenerates in people with Huntington's disease (HD), called the striatum, is almost entirely destroyed in the late stages of the disease. Brain samples from mutant HD gene positive...

There are many indications that fasting promotes longevity. In recent years, much attention has been devoted to so-called caloric restriction mimetics (CMRs), substances that simulate the health-promoting effects of fast...

Bacterial cell division is controlled by both enzymatic activity and mechanical forces, which work together to control its timing and location.

If a doctor expects a treatment to be successful, a patient may experience less pain and have better outcomes, according to a new study. The findings reveal how social interactions between hypothetical healthcare provide...

Immune cells can be the body's defenders and foes at the same time.

A high-resolution bioprinting process has been developed: Cells can now be embedded in a 3D matrix printed with micrometer precision -- at a printing speed of one meter per second, orders of magnitude faster than previou...

Chemotherapy and radiation therapy are commonly used to treat cancer, but are not always effective and can have toxic side effects. Researchers tested a new radiotherapy technique that sends alpha-emitting particles to s...

A recent study showed coloring and open-studio art therapy benefits stressed caregivers of cancer patients.

Pluripotent stem cells can be used to make experimental models of organ systems, but current techniques often produce models that bear limited resemblance to true organs. Researchers developed an improved method to make ...

A school-based human papillomavirus (HPV) immunization program in British Columbia, Canada, is dramatically reducing rates of cervical pre-cancer in B.C. women, according to a new study.

Phagocytosis can be viewed as a primitive immune system used by all cells. When a pathogen is near the cell, the cell membrane will deform to engulf the pathogen and dispose of it. Researchers have found that a two-dimen...

Researchers have grown rabbit and cow muscles cells on edible gelatin scaffolds that mimic the texture and consistency of meat, demonstrating that realistic meat products may eventually be produced without the need to ra...

Some adults see their mothers and fathers as still influencing their own health -- but in very different ways, according to a new study.
