A contagious canine cancer that conquered the world by spreading between dogs during mating likely arose around 6,000 years ago in Asia and spread around the globe through maritime activities, scientists say.

Researchers have published a new 3D bioprinting method that brings the field of tissue engineering one step closer to being able to 3D print a full-sized, adult human heart.

A blood test to detect the brain changes of early Alzheimer's disease has moved one step closer to reality. Researchers report that they can measure levels of the Alzheimer's protein amyloid beta in the blood and use suc...

More than 1 million sepsis survivors are discharged annually from acute care hospitals in the United States. Although the majority of these patients receive post-acute care (PAC) services, with over a third coming to hom...

Scientists have devised a new computational method that reveals genetic patterns in the massive jumble of individual cells in the body. The discovery will be useful in discerning patterns of gene expression across many k...

An experimental vaccine against respiratory syncytial virus (RSV), one of the leading causes of infectious disease deaths in infants, has shown early promise in a Phase 1 human clinical trial. Researchers report that one...

Sudden sensorineural hearing loss (SSNHL) affects five to 27 per 100,000 people annually, with about 66,000 new cases per year in the United States.

Allergies can be life-threatening when they cause anaphylaxis, an extreme reaction with constriction of the airways and a sudden drop in blood pressure. Scientists have identified a subtype of immune cell that drives the...

A national team has just published the largest-ever examination of the state of research on all aspects of youth firearm injury - whether intentional, unintentional or self-inflicted. The bottom-line conclusion: Far more...

A rare, short-lived population of immune cells in the bloodstream may serve as 'periscopes' to monitor immune status via lymph nodes deep inside the body, according to new resesearch.

Researchers were surprised to find that methamphetamine use is not linked with worse health outcomes among burn patients, but was associated with significantly worse discharge conditions for meth-positive patients. Meth-...

Around 22,000 people will be diagnosed this year in the US with acute myeloid leukemia (AML), the second most common type of leukemia diagnosed in adults and children. Researchers have discovered a key reason why this di...

For people who inherited genes that increase their chance of becoming obese, there is hope for keeping the weight off. A study has identified the types of exercise that are especially effective at combating genetic effec...

Researchers report a new imaging system that cancels the chromatic optical aberrations present in a specific person's eye, allowing for a more accurate assessment of vision and eye health. By taking pictures of the eye's...

Researchers developed a new mouse model that could improve the translation of research in mice into advances in human health. The mouse model, which the scientists called 'wildling,' acquired the microbes and pathogens o...

Investigators have shown that the combination of a vaccine and a medicated cream is a promising strategy to dramatically reduce the recurrence of genital herpes.

Biomedical researchers have found a new way to study endometrial diseases such as endometriosis and cancer. They were able to grow three-dimensional cell structures from diseased tissue of patients. The biobank can be us...

Researchers from Tsinghua University and Brown University have discovered a simple way to give a major boost to turbulent heat exchange, a method of heat transport widely used in heating, ventilation and air conditioning...

An international team led by researchers has discovered the energy production mechanism of cancerous cells that drives the growth of the nucleolus and causes tumors to rapidly multiply. The findings could lead to the dev...

Humanitarian crises present major threats to the wellbeing of children, and for more than two decades Child Friendly Spaces have been considered one of the best ways to respond. A recent looked at the impact of Child Fri...

Side impact to the head can lead to rotational accelerations what cause mechanical vibrations to concentrate in the corpus callosum and periventricular region of the brain. Trauma to the side of the head can lead to conc...

Known for its poor prognosis, lung adenocarcinoma is the most common type of lung cancer, responsible for about 4 of 10 diagnoses. Researchers can now distinguish between two pathways where this deadly cancer can develop...
