Assessing brain bleeding in head injuries with new device

In a clinical trial conducted among adults in 11 hospitals, researchers have shown that a hand-held EEG device approved in 2016 by the U.S. FDA that is commercially available can quickly and with 97 percent accuracy rule out if a person with a head injury is likely to have brain bleeding and needs further evaluation and treatment.

Giant shipworm could reveal clues about human medicine, bacterial infections

Northeastern professor Daniel Distel and his colleagues have discovered a dark, slithering 4-foot-long creature that dwells in the foul mud of a remote lagoon in the Philippines. They say studying the animal, a giant shipworm with pinkish siphons at one end and an eyeless head at the other, could add to our understanding of how bacteria cause infections and, in turn, how we might adapt to tolerate or even benefit from them.

New handheld fiber-optic probe brings endoscopic diagnosis of cancer closer to clinic

In an important step toward endoscopic diagnosis of cancer, researchers have developed a handheld fiber-optic probe that can be used to perform multiple nonlinear imaging techniques without the need for tissue staining. The new multimodal imaging probe uses an ultrafast laser to create nonlinear optical effects in tissue that can reveal cancer and other diseases.

Cells grow more naturally in 'spaghetti'

The usual way of cultivating cells is to use a flat laboratory dish of glass. However, inside a human body, the cells do not grow on a flat surface but rather in three dimensions. This has lead researchers at Lund University in Sweden to develop a porous "spaghetti" of tissue-friendly polymers with cavities in which the cells can develop in a more natural way.

Next-generation heart valve regenerates into heart-like tissue

The human heart beats approximately 35 million times every year, effectively pumping blood into the circulation via four different heart valves. Unfortunately, in over 4 million people each year, these delicate tissues malfunction due to birth defects, age-related deteriorations, and infections, causing cardiac valve disease.

Laser printing with nanoparticles holds promise for medical research

Electronic devices that not only can be implanted in the human body but also completely dissolve on their own – known as bioresorbable electronics – are envisioned by many as one of medical technology's next frontiers. A new study by Missouri University of Science and Technology researchers suggests that a laser printing technique using nanoparticles could help unlock a more cost-effective approach to building sturdier and safer components.

Process invented to make sustainable rubber and plastics

Synthetic rubber and plastics used for manufacturing tires, toys, and myriad other products are produced from butadiene, a molecule traditionally made from petroleum or natural gas. But those humanmade materials could get a lot greener soon, thanks to the ingenuity of a team of scientists from three U.S. research universities.
