Although N95 face masks are quite effective at blocking transmission of the COVID-19-causing SARS-CoV-2 virus, they’re also intended to be used only a few times at most. A new removable membrane, however, could make them much more reusable.Continue Rea… Continue reading Peel-off membrane could allow N95 masks to be reused many times
Researchers have created synthetic red blood cells (RBCs) that have all of the useful properties of the real thing, plus a few new tricks. These new cells could be put to work carrying oxygen or drugs through the body, sensing toxins, and other tasks.C… Continue reading New synthetic red blood cells are even better than the real thing
Although 3D printers can produce a wide variety of objects, the size of each item is limited by the size of the printer. Scientists have now developed a way of getting around that limitation, using a resin that expands when heated.Continue ReadingCateg… Continue reading Foaming resin allows for larger 3D-printed objects
It was just a couple of years ago that we heard about a kinder, gentler hair dye that incorporated graphene. Well, scientists have now had success utilizing another, less exotic substance – synthetic melanin.Continue ReadingCategory: ScienceTags: North… Continue reading Synthetic melanin used in less-harsh hair dye
Ordinarily, when a dead body is found, the time of death can be estimated via insect activity or body temperature. Unfortunately, that doesn’t apply if the corpse is in the water. Now, though, a new study suggests that bone proteins could still provide… Continue reading Bone proteins may tell how long a corpse was swimming with the fishes
Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.Continue ReadingCategory: Material… Continue reading Spiders inspire improved nanofiber-handling tech
The colorful glaze on that ceramic mug of yours may look nice, but there’s a chance that it could contain toxic substances. US scientists have thus created a safer type of glaze, that incorporates tiny particles of silver and gold.Continue ReadingCateg… Continue reading Silver and gold used to make safer ceramic glaze
The more clothing that you wear, the warmer you are … right? Well actually, scientists have developed a new textile that both warms wearers in cold environments, and cools them down when things heat up.Continue ReadingCategory: Materials, ScienceTags: … Continue reading Phase-change fabric both warms and cools its wearer
Blind readers will likely be familiar with refreshable braille displays, in which raised dots electronically rise and fall from a flat surface in order to temporarily form braille characters. A new material, however, could make such displays cheaper an… Continue reading “Polyionic” material may make for better braille displays
One of the challenges in designing micro air vehicles (MAVs) lies in the fact that if their battery is large enough to provide much range, it’s too heavy for them to carry. Scientists have developed what could be an alternative, though, in the form of … Continue reading Light-powered wing flaps as long as the sun shines
