You’re already wearing a mask – now consider a face shield and goggles | Adrienne Matei

For better protection, you may need to ... look a little weird and shield your peepersAt first, wearing a face mask felt a bit strange. Now, over five months into North America’s battle with Covid-19, I feel naked in public without one. Will goggles – previously the purview of steampunks and snowboarders – become the next article of protective equipment to go from weird to widespread?...

What kind of face mask best protects against coronavirus?

Your questions answered on what type of mask to wear to cut the risk of getting Covid-19Coronavirus – latest updatesSee all our coronavirus coverageYes. Different types of mask offer different levels of protection. Surgical grade N95 respirators offer the highest level of protection against Covid-19 infection, followed by surgical grade masks. However, these masks are costly, in limited supply,...

New printing process advances 3-D capabilities

More durable prosthetics and medical devices for patients and stronger parts for airplanes and automobiles are just some of the products that could be created through a new 3-D printing technology invented by a UMass Lowell researcher.

Scientists discover new class of semiconducting entropy-stabilized materials

Semiconductors are important materials in numerous functional applications such as digital and analog electronics, solar cells, LEDs, and lasers. Semiconducting alloys are particularly useful for these applications since their properties can be engineered by tuning the mixing ratio or the alloy ingredients. However, the synthesis of multicomponent semiconductor alloys has been a big challenge due...

New studies show how to save parasites and why it's important

An international group of scientists published a paper, Aug. 1, 2020, in a special edition of the journal Biological Conservation that lays out an ambitious global conservation plan for parasites. A separate paper also found that the responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss...

Scientists discover new class of semiconducting entropy-stabilized materials

The design of novel materials with superior characteristics by entropy stabilization is a very dynamic emerging research area in materials science. However, despite recent advances in entropy-stabilized metals and insulating ceramics targeted for structural applications, there is still a dearth of high-entropy semiconductors, which poses a major obstacle for the adoption of high-entropy materials...
