A study shows that in countries where there is a complete ban on all corporal punishment of children there is less fighting among young people. There was 31 percent less physical fighting in young men and 42 percent less...

Gene expression over the course of neural development is significantly associated with a genetic risk for developing schizophrenia, researchers report.

A coalition of major global figures say we must do much more to adapt to our rapidly warming world, and we need to do it fast

Can humans drive economic growth, meet rising demand for food, energy and water, and make significant environmental progress? The short answer is 'yes,' but it comes with several big 'ifs.' New research shows that we can...

New study finds that between 1999 and 2014, only 25 new antibiotics entered the global market. The majority of antibiotics released in this time period originated from Japanese or US companies and were launched in Japan ...

A father's exposure to nicotine may cause cognitive deficits in his children and even grandchildren, according to a new study. The effect, which was not caused by direct secondhand exposure, may be due to epigenetic chan...

Defects in the lymphatic system have been linked to a wide range of health consequences, but new findings of how the system works could lead to future therapies.

Stiffness of the aorta -- more so than blood pressure or subclinical brain disease -- is a key risk factor for dementia. Since aortic stiffness can be reduced by medication and healthy lifestyle changes, these results su...

By studying a chemical produced predominately in the liver, hypertension researchers have found a novel approach to lower blood pressure, even without reducing sodium intake or increasing exercise.

A new study finds that certain environmental conditions like salt concentrations and temperature may precipitate structural changes that take place in myelin sheaths in the onset of multiple sclerosis (MS). Myelin sheath...

Environmental scientists argue that societies should embrace population aging and decrease. They cite multiple reports of the socioeconomic and environmental benefits of population aging, mortality-related decrease, and ...

An age-related increase in estrogen may be the culprit behind inguinal hernias, a condition common among elderly men that often requires corrective surgery. Men could be treated with hormone inhibitor to strengthen muscl...

Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores, sperm and egg cells.

A team of researchers has now engineered a virus nanoparticle vaccine against Bacillus anthracis and Yersinia pestis, tier 1 agents that pose serious threats to national security of the United States. B. anthracis and Y....

Scientists at TU Wien, the University of Innsbruck and the -AW have for the first time demonstrated a wave effect that can lead to measurement errors in the optical position estimation of objects. The work now published ...

Researchers report a father's exposure to nicotine may have lasting effects on the cognitive development of his offspring. The study reports nicotine exposure may cause epigenetic alterations in key genes within the fath...

Researchers have identified the signaling molecules that activate the lymphatic pathway. The study also identified the cells that produce the signaling molecule and how they are used in lymphatic development.

Using non-invasive brain stimulation, researchers shed light on the neurobiology underlying implicit biases.

Mice are more active and have attention problems if their fathers had nicotine in their diet, perhaps because the chemical triggers epigenetic changes in sperm

A new neuroimaging study reveals how dogs process words they have been taught to associate with objects. Findings suggest dogs have a rudimentary neural representation of meaning for words they have been taught.

Research has yielded new insights into the environment surrounding different types of lung tumors, and described how these complex cell ecosystems may in turn ultimately affect response to treatment.
