Scientists report on the status of recent research and share their vision about the future of wearable neuroprosthetics.

Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today's electronics.

Quantum dots are very small particles that exhibit luminescence and electronic properties different from those of their bulk materials. As a result, they are attractive for use in solar cells, optoelectronics, and quantu...

The protein moesin could be a target for cancer immunotherapy. New data suggest that moesin promotes conversion of naive T cells into regulatory T cells that suppress the immune response against cancer. Inhibiting moesin...

Patients who are cured of Hodgkin lymphoma are at a high risk of developing a second type of cancer, particularly if they have a family history of the disease, a major new study reports.

Omega-3 fish oil supplements prescribed by a healthcare provider may be reasonable for patients who have had a heart attack. Patients with heart failure may also benefit from supplementation with omega-3 fish oil. Howeve...

Prostaglandins been linked to the sensory perception of pain, but their role in the emotional response to pain is unclear. A new study has demonstrated that the aversive effects of inflammatory pain are driven by prostag...

A new study offers evidence confirming what many parents already know: the wait to see a developmental pediatrician -- only 1,000 of whom exist nationally -- is lengthy and delays diagnostic evaluations that could be imp...

Researchers have refined a method to modify an antibody's sugar group structure, which plays a large role in determining an antibody's ability to activate the immune response. By determining which specific sugar combinat...

New work from a team including Carnegie's Guoyin Shen and Yoshio Kono used high pressure and temperature to reveal a kind of "structural memory" in samples of the metal bismuth, a discovery with great electrical engineer...

Fluorescent compounds make a South American tree frog much brighter at night, and the trait may be more widespread in nature than we realise

Although Zika and dengue are considered different virus "species," they are so closely related that the immune system treats Zika just like another version of dengue, report researchers. Their latest study shows that pre...

A new class of male sex hormones known as androgens plays a key role in the development of polycystic ovary syndrome (PCOS), new research shows.

While proteins that control organ growth accumulate around the edges of cells, they actually function at a different cellular site, new research suggests.

A new signaling system has been discovered that epithelial cells use to coordinate their individual movements and efficiently move tissues, report scientists.

In a new report, researchers describe how inflammation can go unchecked in the absence of a certain inhibitor called NLRP12, adding that beneficial bacteria may be the key to helping to reverse a cycle of gut inflammatio...

Pancreatic cancer has the lowest survival rate among all major cancers, largely because physicians lack diagnostic tools to detect the disease in its early, treatable stages. Now, a team of investigators has developed a ...

A researcher has found a way that prostate cancer cells hijack the body's bone maintenance, facilitating the spread of bone cancers present in some 90 percent of prostate-cancer fatalities.

One of the many challenges with existing HIV therapies is that a dormant version of the virus is always lurking in the background, ready to attack the immune system as soon as treatment is interrupted. Now, new research ...

Researchers have mapped how the malaria drug mefloquine works, providing a route to make effective alternatives and combat rising drug resistance.

Scientists have reported a major breakthrough in targeting the causes of many diseases, using a 'kiss of death' to destroy proteins which had previously been regarded as 'undruggable.'

Researchers have discovered that a greater number of breast cancers are genetically similar to rarer cases with faulty BRCA1 or BRCA2 genes. The results open up the possibility of up to 20 percent of women being treated ...
