Missing link in coronavirus jump from bats to humans could be pangolins, not snakes

31-Mar-2020 - As scientists scramble to learn more about the SARS-CoV-2 coronavirus, two recent studies of the virus' genome reached controversial conclusions: namely, that snakes are intermediate hosts of the new virus, and that a key coronavirus protein shares "uncanny similarities" with an HIV-1 protein. ...

Paper-based test could diagnose Lyme disease at early stages

20-Dec-2019 - After a day hiking in the forest, the last thing a person wants to discover is a tick burrowing into their skin. Days after plucking off the bloodsucking insect, the hiker might develop a rash resembling a bull's-eye, a tell-tale sign of Lyme disease. Yet not everybody who contracts Lyme disease ...

4D imaging with liquid crystal microlenses

22-Nov-2019 - Most images captured by a camera lens are flat and two dimensional. Increasingly, 3D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4D imaging, which adds information on light polarization, could open up even more possibilities, but ...

Fungal compound deodorizes skunk smell

29-Jul-2019 - Being sprayed by a skunk is no fun for people or their pets, and the strong, stinky secretions can serve as a nasty reminder of the wildlife encounter for days or weeks. Available "de-skunking" formulas often either don't work well or can irritate the skin and eyes. Now, researchers reporting in ...

'Semi-synthetic' bacteria churn out unnatural proteins

19-Jul-2019 - Synthetic biologists seek to create new life with forms and functions not seen in nature. Although scientists are a long way from making a completely artificial life form, they have made semi-synthetic organisms that have an expanded genetic code, allowing them to produce never-before-seen ...

Self-healing DNA nanostructures

03-Jun-2019 - DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don't persist long in biological environments because of enzymes called nucleases that degrade DNA. Now, ...

Ragweed compounds could protect nerve cells from Alzheimer's

17-May-2019 - As spring arrives in the northern hemisphere, many people are cursing ragweed, a primary culprit in seasonal allergies. But scientists might have discovered a promising new use for some substances produced by the pesky weed. In ACS' Journal of Natural Products, researchers have identified and ...

Researchers grow cells in 'paper organs'

03-May-2019 - Long before scientists test new medicines in animals or people, they study the effects of the substances on cells growing in Petri dishes. However, a 2D layer of cells is a poor substitute for the much more complex 3D structure of tissues in organs. Now, researchers reporting in the ACS journal ...

Biosensor 'bandage' collects and analyzes sweat

23-Apr-2019 - Like other biofluids, sweat contains a wealth of information about what's going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin's surface, can be time-consuming and messy. Now, researchers have developed a bandage-like biosensor ...
