Many people would face the lowest risk of dying if their BMI was 26 -- which is considered overweight, new research suggests.

A new report examines global and national trends in the fatal and nonfatal burden of diseases and injuries among children and adolescents in 188 countries based on results from the Global Burden of Disease 2013 study.

In patients suffering from Type 1 diabetes, the immune system attacks the pancreas, eventually leaving patients without the ability to naturally control blood sugar. These patients must carefully monitor the amount of su...

Alzheimer's disease is a degenerative brain disease that leads to cognitive decline, dementia and ultimately death, mostly in the elderly. It's already a huge health burden, and it's getting worse as the population ages....

A soy isoflavone derivative that goes by the scientific moniker, (S)-equol, has proven potent for mitigating menopausal symptoms. However, it has been impossible to produce in quantities sufficient for widespread commerc...

A simple analysis of chromosomal breaks in sperms can help guide choice of fertility treatment and, thereby, increase chances of successful assisted reproduction for involuntary childless couples, new research shows.

Scientists have linked increased resistance of hemagglutinin protein to acidic pH with emergence of the 2009 H1N1 pandemic flu virus; the finding may help spot future pandemic viruses.

A new mouse-human modeling system has been created that could be used to study neural crest development as well as the modeling of a variety of neural crest related diseases, including such cancers as melanoma and neurof...

Among the Pueblo Indians of northern New Mexico, disease didn't break out until nearly a century after their first contact with Europeans, following the establishment of mission churches in the seventeenth century, a tea...

By mimicking the way orchids, calla lilies and other plants bend and twist, scientists have created shape-shifting "4D-printed" structures that they say could one day help heal wounds and be used in robotic surgical tool...

Tests on 35 species show that relative brain size predicts a carnivore's ability to solve problems, with bears beating meerkats

A new species of daddy longlegs has been unearthed lurking on the forest floor in the mountains of Oregon, and it's a relative beast compared to its close cousins.

A team of scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard John A. Paulson School of Engineering and Applied Sciences has evolved their microscale 3D printing t...

The most commonly used test for tuberculosis fails to accurately diagnose TB in up to 50 percent of pregnant women who are HIV+, new research has found. The research is believed to be the first study to compare the accur...

A gene that is often lost in childhood cancer plays an important role in the decision between life and death of certain cells, according to a new study. Researchers have discovered the process by which that gene, KIF1B-?...

Researchers have uncovered previously unappreciated means by which epigenetic information contained in the egg influences the development of the placenta during pregnancy. The research, which was performed in mice, indic...

Evolution likes to borrow. It can take an already-successful biological structure and alter it until it serves a new function. Two independent groups studying the proteins that organize gut microvilli now suspect that th...

As the virus continues to spread, scientists are trying to understand how it went from causing sporadic, contained outbreaks to threatening almost an entire hemisphere

Treatment of multiple sclerosis (MS) and other inflammatory diseases may benefit by new findings from a study that identified potential therapeutic targets for a devastating disease striking some 2.3 million people world...

Biomedical engineering researchers have developed a technique for creating microscopic 'depots' for trapping drugs inside cancer tumors. In an animal model, these drug depots were 10 times more effective at shrinking tum...

The record-breaking snowfall seen in the US over the weekend may become more common if Atlantic ocean current is slowing down as some suggest
