In 2019, researchers witnessed the consequences of an extreme heat event at Punta Tombo in Argentina, one of the world's largest breeding colonies for Magellanic penguins. On Jan. 19, temperatures at the site spiked in the shade to 44 C, or 111.2 F, killing at least 354 penguins. Nearly three-quarters of the penguins that died were adults, many of which likely died of dehydration, based on...
California imposes water restrictions as drought drags on
Californians won't be able to water their lawns for 48 hours after rainstorms or let their sprinklers run onto the sidewalk under mandatory water restrictions state regulators adopted Tuesday as a drought continues despite heavy December rain and snow.
Exploring growth within a confined space
Grow a tomato inside a square box, and you'll end up with a square tomato. It's an experiment that shows clearly how confinement can influence a body's evolving shape.
Study finds fertilization affects soil microbial biomass and residue distribution by changing root biomass
Increasing nitrogen (N) and phosphorus (P) input is one of the major contributors to anthropogenic climate change, which can regulate the sequestration and storage of soil organic carbon (SOC) by changing microbial communities and their residues, the significant component of stable SOC. However, it remains unclear how N and P fertilization influence aggregate-associated microbial communities and...

Real-time alert system heralds new era in fast radio burst research
McGill University scientists have developed a new system for sharing the enormous amount of data being generated by the CHIME radio telescope in its search for fast radio bursts (FRBs), the puzzling extragalactic phenomenon that is one of the hottest topics in modern-day astronomy.
Researchers identify new bacteria and viruses on human skin
Researchers at EMBL's European Bioinformatics Institute (EMBL-EBI), the National Institutes of Health (NIH) National Human Genome Research Institute (NHGRI), the NIH National Institute of Arthritis and Musculoskeletal and Skin Diseases, and colleagues have identified new bacterial and fungal species, as well as viruses in the human skin microbiome.
US snowstorm strands drivers for 20 hours and counting
The snow storm is over but the travel misery is not: drivers on a major highway outside Washington reported Tuesday they have been stuck in their cars in freezing weather for 20 hours or more.
Mass die-off of Magellanic penguins seen during 2019 heat wave
In June 2021, an unprecedented heat wave hit the Pacific Northwest and Canada, killing an estimated 1,400 people. On June 28, Seattle reached 108 F—an all-time high—while the village of Lytton in British Columbia recorded Canada's highest-ever temperature of 121.3 F on June 29, the day before it was destroyed by a heat-triggered wildfire.
Gravitational action of sun and moon influences behavior of animals and plants, study shows
The rhythms of activity in all biological organisms, both plants and animals, are closely linked to the gravitational tides created by the orbital mechanics of the sun-Earth-moon system. This truth has been somewhat neglected by scientific research but is foregrounded in a study by Cristiano de Mello Gallep at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and Daniel...
Plasma-based engineering creates contact-killing, antifouling, drug-release surfaces
The deepening concern over antibiotic-resistant infections, coupled with prevailing hospital-acquired infections from surgical tools, implants, and heavily touched surfaces, has ramped up antimicrobial material development in recent years.
Plasma-based engineering creates contact-killing, antifouling, drug-release surfaces

Conventional wet-chemistry methods used to create biocidal materials are complex, time-consuming, and expensive. Researchers present a tutorial in which they explore a promising alternative called plasma-enabled surface engineering. The technology relies on nonequilibrium plasma that produces chemical reactions to change the properties at the material surface. Reactions can be manipulated by...
Custom finger clip offers a new way to measure blood pressure, other vitals

Monitoring a person's blood pressure on a regular basis can help health care professionals with early detection of various health problems such as high blood pressure, which has no warning signs or symptoms. However, many things can alter an accurate blood pressure reading, including a patient's nervousness about having their blood pressure taken at a doctor's office, otherwise known as 'white...

Webb telescope fully deploys sunshield in mission milestone
The James Webb Space Telescope fully deployed its tennis-court sized sunshield Tuesday, a critical milestone for the success of its mission to study every phase of cosmic history, NASA said.
Second and third layers of Webb telescope sunshield fully tightened
The Webb team has completed tensioning for the first three layers of the observatory's kite-shaped sunshield, 47 feet across and 70 feet long.
Coughing downward reduces spread of respiratory droplets: study
With many people heading indoors for the winter months and respiratory droplets acting as a major contributor to COVID-19 spread, the scientific community has renewed interest in the dynamics behind how they spread. Modeling such behavior in a variety of scenarios for particles that range from less than 1 micrometer in size to 1,000 micrometers proves challenging.
Orion's fireplace: New image of the Flame Nebula
Orion offers you a spectacular firework display to celebrate the holiday season and the new year with this new image from the European Southern Observatory (ESO). But no need to worry, this iconic constellation is neither exploding nor burning. The "fire" you see in this holiday postcard is Orion's Flame Nebula and its surroundings captured in radio waves—an image that undoubtedly does justice...
Risk vs. reward: How towns care for trees varies
When a hurricane or other violent storm blows through a community, one of the first pictures you're likely to see is a fallen tree.
