Scientists at ETH Zurich and the South African company Strait Access Technologies are using 3-D printing to produce custom-made artificial heart valves from silicone. This could help meet an aging population's growing demand for replacement heart valves.
The human heart has four...
When it comes to inpatient treatment of a range of mental health and mood disorders -- from anxiety and depression to schizophrenia, suicidality and acute psychotic episodes -- a new study advocates for exercise, rather than psychotropic medications, as...
A large-scale genomic analysis has revealed some of the inner workings of the body clock, shedding new light on how it links to mental health and disease.
The study, published in Nature Communications, suggests that being genetically programmed to rise...
Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to...
Regular use of a common type of medication, such as aspirin and ibuprofen, significantly improves survival for a third or more patients with head and neck cancer, a new study led by UC San Francisco has found.
Non-steroidal anti-inflammatory drugs,...
In satellite photos of the Earth, clouds of bright green bloom across the surface of lakes and oceans as algae populations explode in nutrient-rich water. From the air, the algae appear to be the primary players in the ecological...
The most deadly aspect of breast cancer is metastasis, cancer cells spreading throughout the body. Researchers at the University and the University Hospital of Basel have now discovered a substance that suppresses the formation of metastases. In the journal...
Instead of searching for a needle in a haystack, what if you were able to sweep the entire haystack to one side, leaving only the needle behind? That's the strategy researchers in the University of Georgia College of Engineering...
In the course of every single cell division, the genetic information on the chromosomes must be distributed equally between the newly developing daughter cells. The enzyme separase plays a decisive role in this process. Susanne Hellmuth and Olaf Stemmann...
Boston University researchers have developed a new, "intelligent" metamaterial—which costs less than ten bucks to build—that could revolutionize magnetic resonance imaging (MRI), making the entire MRI process faster, safer, and more accessible to patients around the world. The technology,...
Quantitative biologists David McCandlish and Juannan Zhou at Cold Spring Harbor Laboratory have developed an algorithm with predictive power, giving scientists the ability to see how specific genetic mutations can combine to make critical proteins change over the course...
