Bioengineers grow living bone for facial reconstruction Posted: 04 Aug 2016 02:24 PM PDT Researchers have engineered living bone tissue to repair bone loss in the jaw, a structure that is typically difficult to restore. They grafted customized implants into pig jaws that resulted in integration and function of the engineered graft into the recipient's own tissue.

Multitasking proteins: Unexpected properties of galectin-3 Posted: 04 Aug 2016 02:16 PM PDT Biochemistry research on lectins and proteoglycans have been around as long as Frank Sinatra tunes. So finding out that these proteins interact is like discovering Sinatra and Elvis started a band way back when. Researchers explain how this finding could impact cancer and immune system research.

Drink-seeking rats provide sobering look into genetics of alcoholism Posted: 04 Aug 2016 12:27 PM PDT Alcohol-craving rats have provided researchers with a detailed look into the complicated genetic underpinnings of alcoholism.

Detailed structure of cell's garbage disposal unit reveals surprise in how it is targeted by cancer drugs Posted: 04 Aug 2016 12:27 PM PDT Cancer cells are more dependent on a cellular garbage disposal unit -- the proteasome -- than healthy cells, and cancer therapies take advantage of this dependency. Scientists have determined the proteasome's 3D structure in unprecedented detail and have deciphered the exact mechanism by which inhibitor drugs block the proteasome. Their surprising results will pave the way to develop more effective treatments.

Vaccine candidates protect against Zika virus in rhesus monkeys Posted: 04 Aug 2016 12:25 PM PDT A ZIKV purified inactivated virus Zika vaccine candidate provided robust protection against the virus in rhesus monkeys in a new preclinical study. Findings support advancing the candidate to human trials.

Goodbye, implants rejection! Posted: 04 Aug 2016 11:22 AM PDT A group of physicists developed a way to use the therapeutic effect of heating or cooling the tissues due to the magnetocaloric effect.

Don't freestyle 'swimmer's shoulder' injuries Posted: 04 Aug 2016 11:12 AM PDT Elite and competitive swimmers log between 60,000 and 80,000 meters weekly -- swimming the length of an Olympic-sized pool 1,200 times -- which places significant stress on their shoulder joints.

Vitamin D levels may drop when women stop using birth control Posted: 04 Aug 2016 10:54 AM PDT Women risk having their vitamin D levels fall when they stop using birth control pills or other contraceptives containing estrogen, according to a new study.

How proteins control gene expression by binding both DNA and RNA Posted: 04 Aug 2016 07:23 AM PDT Proteins that bind DNA or RNA are usually put in different categories, but researchers recently showed how the p53 protein has the capacity to bind both and how this controls gene expression on the levels of both transcription (RNA synthesis) and mRNA translation (protein synthesis).

Health-care costs are bad medicine Posted: 04 Aug 2016 07:16 AM PDT New research shows one in four chronically ill Australians is skipping health care because of high costs.

Schizophrenia simulator: When chemistry upends sanity's balance Posted: 04 Aug 2016 07:16 AM PDT Schizophrenia goes hand in hand with brain chemistry out of kilter, and treatment options for a major symptom aren't great. Biomedical engineers data-mined the collective scientific knowledge of a major symptom, the disruption of working memory, to build a remarkably accurate simulator that can help researchers and doctors devise new treatments.

Genomics study points to origins of pollen allergens Posted: 04 Aug 2016 07:16 AM PDT A new study has provided the first broad picture of the evolution and possible functions in the plant of pollen allergens.

Brains of overweight people 'ten years older' than lean counterparts at middle-age Posted: 04 Aug 2016 04:12 AM PDT From middle-age, the brains of obese individuals display differences in white matter similar to those in lean individuals ten years their senior, according to new research.

View that sickle cell trait increases mortality risk challenged Posted: 03 Aug 2016 06:42 PM PDT Health experts have long believed that sickle cell gene variants, which occur in about one in 13 African-Americans, increase the risk of premature death, even when people carry only a single copy of the variant. But health records of nearly 50,000 active-duty US Army soldiers between 2011 and 2014 shows that's not the case.

Insomnia? Oversleeping? Both may increase your risk of stroke Posted: 03 Aug 2016 06:42 PM PDT There is growing evidence that sleep disorders like insomnia and sleep apnea are related to stroke risk and recovery from stroke, according to a recent literature review.
