A new study demonstrates that regional cerebral blood flow is reduced in the Broca's area -- the region in the frontal lobe of the brain linked to speech production -- in persons who stutter. More severe stuttering is as...

Scientists have discovered the signaling pathways that help hair follicles and sweat glands form during development, and identified the mechanism that allows both of these features to coexist in human skin. The findings ...

In neonatal health, knowing the exact time of conception saves lives. Two data scientists have a mathematical solution to rectify rough estimates.

The largest study to date of a condition known as 'chemo-brain' shows that women with breast cancer report it's a substantial problem after chemotherapy for as long as six months after treatment, according to investigato...

Scientists have uncovered the chemical process behind anti-cancer properties of a spicy Indian pepper plant called the long pepper, whose suspected medicinal properties date back thousands of years.

A new study finds that the current Chinese cesarean rate is substantially lower than what had been reported by the World Health Organization, and is comparable to the US rate for the same year.

Immunotherapy is a fast growing area of cancer research. It involves developing therapies that use a patient's own immune system to fight and kill cancer. Medical researchers are working on a new vaccine that would help ...

Researchers put forth the notion of overfat, a condition of having sufficient excess body fat to impair health. After review of current data and scientific studies they argue how, in addition to most of those who are ove...

Scientists have shown in mice that excess pounds can simply be melted away by converting unwanted white fat cells into energy-consuming brown slimming cells. In a recent study, the university researchers show why the inf...

Lyme disease has been spreading across the United States over the past several decades, and a new study has confirmed that ticks carrying the disease are present in eastern national parks.

Biomedical engineers have created a smart, targeted drug delivery system using immune cells to attack cancers.

Topological insulators, an exciting, relatively new class of materials, are capable of carrying electricity along the edge of the surface, while the bulk of the material acts as an electrical insulator. Practical applica...

Now anyone with a 3D printer can print their own tractor beam device for pulling small objects with sound.

Medication, meningitis and being struck by lightning have all affected one woman's synaesthesia, but remarkably it soon returned in exactly the same form

One of the most biodiverse lakes in Europe, home to many species found nowhere else, is under threat from the development of a resort and hydropower dams

What if you could travel around the world with the click of a button, the only requirement being a headset and internet connection? Virtual reality is already making this possible for those who seek it, and it may become...

Last year Asier Marzo, then a doctoral student at the Public University of Navarre, helped develop the first single-sided acoustic tractor beam--that is, the first realization of trapping and pulling an object using soun...

Replacing a hydrogen atom by an iodine atom in insulin, the hormone retains its efficacy but is available more rapidly to the organism. Researchers were able to predict this effect based on computer simulations and then ...

Using solar cells placed under the skin to continuously recharge implanted electronic medical devices is a viable one. Swiss researchers have done the math, and found that a 3.6 square centimeter solar cell is all that i...

Memory chips are among the most basic components in computers. The random access memory is where processors temporarily store their data, which is a crucial function. Researchers from Dresden and Basel have now managed t...

Fishing methods meant to keep marine ecosystems healthy may unintentionally aggravate climate change

Physical activity benefits diabetics and others with insulin resistance. One of the reasons is that a single bout of physical activity increases the effectiveness of insulin. Thus, physical activity helps to reduce the r...
