A teacher was killed and six other people injured when an 11-year-old student opened fire Friday at a private school in the northern Mexican state of Coahuila, officials said.

Using magnetic resonance imaging (MRI) to measure the effect of weight loss on the upper airway in obese patients, researchers found that reducing tongue fat is a primary factor in lessening the severity of OSA.

We all know that a brush with poison ivy leaves us with an itchy painful rash. Now researchers have discovered the molecular cause of this irritation. The finding brings us a step closer to designing agents to block this mechanism and sheds light on other serious skin conditions, such as psoriasis.

People with psoriasis have an increased risk for cardiovascular disease. Treating psoriasis may help improve cardiovascular symptoms by reducing skin inflammation, which in turn leads to less inflammation elsewhere in the body, say researchers.

Researchers at Okayama University describe in Proceedings of the National Academy of Sciences the effect of clodronate on the regulation of adenosine triphosphate release and its potential as a drug...

One of the causes of breast cancer may be inflammation triggered by harmful bacteria suggest researchers. Scientists advise consuming natural yogurt, which contains beneficial bacteria which dampens inflammation and which is similar to the bacteria found in breastfeeding mothers. Their suggestion is that this bacteria is protective because breast feeding reduces the risk of breast cancer. The consumption of yogurt is also associated with a reduction in the risk of breast cancer.

Little organs within cells called lysosomes digest unwanted material. And like stomachs, they must be acidic to do so. If they aren't, cells stop growing. Researchers wanted to know why.

West Nile virus (WNV) inhibits autophagy -- an essential system that digests or removes cellular constituents such as proteins -- to induce the aggregation of proteins in infected cells, triggering cell death and brain inflammation (encephalitis), according to researchers.

It is claimed so-called polygenic scores for education could help teachers, but a large study shows they don't reveal anything useful about individuals

The number of blacktip sharks off Florida's shoreline is down nearly 60 percent from 2011. Researchers say warming waters may be the reason.
