AI-Driven Dynamic Face Mask Adapts To Exercise and Contamination Levels

Many people have become familiar with using face masks to protect themselves and others throughout the coronavirus pandemic, yet that does not mean the masks are consistently comfortable, especially during exercise. Now, scientists reporting in ACS Nano have created a dynamic respirator that regulates its pore size in response to altering conditions, such as...

Shielding Crops From Pests With Cutting-Edge Compound Solution

© iStock/pixartdesign Researchers came up with a novel chemical solution based on the scents of predator bugs to repel herbivorous pests and safeguard crops. Herbivorous insects are currently a major danger to farmers' crop output. Predator insects that feed on herbivorous insects emit smells that the insects can detect. To escape being eaten, bugs change their...

Which Volcano is the World’s Largest?

Map of World's Largest Volcanoes. Credit: Hobart M. King, Ph.D. The map displayed above illustrates the locations of the world's major volcanoes. The Tamu Massif, which is located on the Shatsky Rise in the northwest corner of the Pacific Ocean, has the greatest mass and footprint. Mauna Kea, located on the Hawaiian island of Oahu, has...

Mount Rainier – Living Safely With a Volcano in Your Backyard

Mount Rainier towers over Seattle's growing suburbs and Tacoma, Washington, rising more than 3 miles (14,410 feet) above sea level. Over the course of a year, about two million visitors explore Mount Rainier National Park to see the volcano, glaciers, forested ridges, and alpine meadows. The volcano's elegance, though, is deceiving. Mount Rainier is considered...

Comprehensive Tracking Gives Timely Cautions of Volcano Rekindling

Volcanic monitoring types and methods employed. Credit: USGS Volcano Hazards Program Scientists must employ numerous tools to listen to and see activity inside a volcano in order to keep a watch on it. The USGS Volcano Hazards Program monitors volcanoes for signals of change that indicate volcanic reawakening. Surveillance must include several observations (earthquakes, ground...

Harvard’s 3D-Printed Eardrum Repair Patch is Awaiting Market Acceptance

Eardrum perforations can cause pain in addition to hearing loss and are difficult to repair. The PhonoGraft is a 3D-printed implant created by Harvard scientists that may cure harm by stimulating natural cell renewal. It is presently available for sale. The eardrum, or tympanic the membrane itself, is a thin, round segment of tissue that...

Climate Disasters ‘Block Access to Women’s Healthcare’

In accordance to a survey, disasters brought on by climate change increase the vulnerability of women and girls since crucial health services, like family planning, are neglected during such times. According to a report by the United Nations Population Fund (UNFPA), situations like violent storms prevent access to sexual and reproductive health care. In turn,...

Exercise During Pregnancy Improves Children’s Lung Function

Scientists have discovered more proof that exercising while pregnant benefits both the mother and the unborn child. According to a study presented today (Sunday) at the "virtual" European Respiratory Society International Congress, Dr. Hrefna Katrin Gudmundsdottir asserted that a study of 814 infants had for the first time established a link between infants born to...

Something Mysteriously Eliminated About 90 Percent of Sharks 19 Million Years Ago

Credit: GERARD SOURY/THE IMAGE BANK/GETTY IMAGES Around 19 million years ago, something horrible happened to sharks. Fossils amassed from sediments in the Pacific Ocean reveal a previously unidentified and shocking shark extinction event. During this event, the populations of the predators abruptly dropped by as much as 90 percent, researchers report in the journal Science on June 4....

Uncovering Concealed Local States in a Quantum Material

Scientists have collected evidence of local symmetry breaking in a quantum material upon heating. They believe these local states are associated with electronic orbitals that serve as orbital degeneracy lifting (ODL) "precursors" to the titanium (Ti) dimers (two molecules linked together) formed when the material is cooled to low temperature. (Electron orbitals are considered...
