Enzymes produced by gut bacteria can make universal blood more efficiently

27.8.2018   |   Press monitoring

For several decades researchers have been working to find an effective way to convert one blood type into another. Type O blood, often considered the universal blood type, is most useful in emergency situations. New research presented at the National Meeting & Exposition of the American Chemical Society has revealed that an enzyme produced by gut...

Newly discovered class of molecules may boost cancer vaccine development

24.8.2018   |   Press monitoring

Cancer vaccines are designed to heighten the immune system's awareness of a tumor's unique features, boosting its ability to recognize, attack, and destroy the cancer. To date, effective cancer vaccines have focused on what are called "neoantigens," tumor-specific peptides that result from acquired mutations. But not every tumor produces...

Nanobot pumps destroy nerve agents

22.8.2018   |   Press monitoring

Once in the territory of science fiction, "nanobots" are closer than ever to becoming a reality, with possible applications in medicine, manufacturing, robotics and fluidics. Today, scientists report progress in developing the tiny machines: They have made nanobot pumps that destroy nerve agents, while simultaneously administering an...

The wheat code is finally cracked

20.8.2018   |   Press monitoring

Today in the international journal Science, the International Wheat Genome Sequencing Consortium (IWGSC) published a detailed description of the genome of bread wheat, the world's most widely cultivated crop. This work will pave the way for the production of wheat varieties better adapted to climate challenges, with higher yields, enhanced...

First ever RNA-based gene-silencing drug approved by FDA, and it\'s not cheap

17.8.2018   |   Press monitoring

Twenty years after the breakthrough discovery illustrating how RNA interference can be used to silence certain genes, and over a decade after the research won a Nobel prize, the U.S. Food and Drug Administration has approved the first drug utilizing this method for adult clinical treatment. The condition, hereditary transthyretin-mediated...

3D-printed nerve stem cells could help patch up spinal cord injuries

15.8.2018   |   Press monitoring

Spinal injuries can be like downed power lines – even if everything on either side of the injury is perfectly functional, the break can effectively shut down the whole system. Now, researchers at the University of Minnesota have designed a device that could link everything back together again. A silicone guide, covered in 3D-printed neuronal stem...

Scientists discover fat-blocking effect of nanofibers

13.8.2018   |   Press monitoring

Tiny balls of nano-sized cellulose fibres added to food reduced fat absorption by up to half in laboratory and animal experiments, report scientists from Nanyang Technological University, Singapore (NTU Singapore) and Harvard University, United States. This discovery could aid in the global battle against obesity, as experiments done in a...

Wearable yeast colonies act as canaries for radiation exposure

10.8.2018   |   Press monitoring

The radiation dose of an X-ray scan is fine for patients getting them every now and then, but health risks stack up for radiologists who are exposed to it all day, every day. Layers of protective gear help, but now researchers at Purdue University have developed a living device for these workers, using yeast colonies in wearable patches to...

Drug-resistant bacteria are growing tolerant to strong alcohol-based hand rubs

8.8.2018   |   Press monitoring

Over the past couple of decades the increased use of alcohol-based hand sanitizers and disinfectants in hospitals has been incredibly successful in reducing cases of deadly golden staph infections. However, a new study has found that some bacteria are now becoming resistant to these alcohol-based sanitizers. The research began when Professor Paul...

You Can Run, but Your DNA Can’t Hide

6.8.2018   |   Press monitoring

At Stanford University, a microfluidic chip has been developed that efficiently extracts sperm from rape kit samples. The chip’s channels, which are coated with Sialyl-LewisX, a carbohydrate ligand for sperm-egg binding, will capture a perpetrator’s sperm, but not a victim’s epithelial cells, which are easily washed away. After sperm are captured...
