Two analyses examined issues of sexual orientation and intimate partner violence, including its impact on substance abuse and physical and mental health.

There are many enduring mysteries regarding the composition of the Earth's atmosphere but one may be a little closer to being solved. Researchers have discovered a microbial soil process that helps ensure that the explosive gas hydrogen remains at trace levels. 

In recent decades it was found that about 80 percent of all hydrogen released into the air is rapidly removed through soil activity, but exactly what is recycling it, and how, has remained unclear.

By now, almost everyone understands computers and that current technologies for writing, storing, and reading information are either charge-based or spin-based.

Spin-based devices operate on the principle that in materials like iron, electron spins generate magnetism and the position of the north and south pole of the magnet can be used to store the zeros and ones. This technology is behind both magnetic stripe cards and terabyte computer hard disks. Since these devices are based on spin, they are more robust against charge perturbations but the drawback is that in order to reverse the north and south poles of the magnet, i.e., flip the zero to one or vice versa, the magnetic bit has to be coupled to an electro-magnet or to another permanent magnet.

Health costs saved or gained, like all claims about what did not happen, are made-up metrics, so we can either accept or not accept the notion that 4 million criminals are now going to have free health care and that will cost us less money than if they didn't have health care and that caused them to commit more crimes and then get health care.

Politicians coming up on a mid-term election have to take their health reform victories where they can get them and the work led by Marsha Regenstein, PhD, who is a professor of health policy at

Scientists at Imperial College London have discovered that iron deficiency may increase stroke risk by making the blood more sticky.

The findings, published in the journal PLOS ONE, could ultimately help with stroke prevention.

Every year, 15 million people worldwide suffer a stroke. Nearly six million die and another five million are left permanently disabled. The most common type, ischaemic stroke, occurs because the blood supply to the brain is interrupted by small clots.

In the last few years, several studies have shown that iron deficiency, which affects around two billion people worldwide, may be a risk factor for ischaemic stroke in adults and in children. How iron deficiency could raise stroke risk has been a puzzle for researchers.

Glioblastoma is the most common primary malignant adult brain tumor and, despite treatment advances in recent years, the average survival of patients enrolled in clinical trials is less than 16 months.

Few patients live beyond five years.

Glioblastoma
tumors are characterized by angiogenesis — the formation of new blood vessels that support tumor growth stimulated by the GBM-produced vascular endothelial growth factor A (VEGF-A).

Bevacizumab is a monoclonal antibody that targets VEGF-A production to block the growth of tumor-derived blood vessels.
