Investigating dense plasmas with positron waves
Astrophysical and lab-created plasmas under the influence of magnetic fields are the source of intense study. New research seeks to understand the dynamics of position waves traveling through these clouds of highly ionized gas......»»
Environmental physicist discusses marine heat waves
An extraordinary heat wave is assailing the world's oceans with an intensity that is surprising climate researchers. Environmental physicist Nicolas Gruber provides some context......»»
Understanding compound events in a changing climate
Climate change has made extreme weather events more frequent and intense worldwide. Some examples of climate-related disasters in recent years include the serious flooding in Venice, Italy in 2019, the terrible heat waves and wildfires in Australia i.....»»
New Indo-European language discovered during excavation in Turkey
An excavation in Turkey has brought to light an unknown Indo-European language. Professor Daniel Schwemer, an expert for the ancient Near East, is involved in investigating the discovery......»»
Mussels able to adjust heart rate to cope with marine heat waves
Mussels are among the ultimate superfoods, high in vitamin B12, omega-3 and great for the heart. Now, new research shows they are also likely to withstand marine heat waves by adjusting their body functions......»»
Investigating invasive plants as roadside contaminant removal tools
Tall, densely growing Phragmites and cattail (Typha) are familiar plants alongside highways and byways in the northern United States, flourishing in salty roadsides and degraded wetland environments created by chemicals applied to roads in the colder.....»»
NASA"s Atmospheric Waves Experiment completes space environment tests
NASA's Atmospheric Waves Experiment (AWE) has successfully completed critical space environment tests. Planned for launch to the International Space Station in November 2023, AWE will study atmospheric gravity waves in Earth's atmosphere to help us b.....»»
Exotic tree species in the forest mean loss of grazing land for reindeer
Semi-domesticated reindeer avoid winter habitats with exotic lodgepole pine (Pinus contorta), introduced from Northern America. Reduced food supply and dense stands probably contribute to the reindeers' avoidance behavior of areas with tall P. contor.....»»
NASA team simulates a glimpse of our galaxy in gravitational waves
Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wave observatories expected to la.....»»
Ensuring effective visual communication of climate change
The consequences of a warming climate frequently dominated the news this summer, from devastating wildfires and floods to deadly heat waves across the globe. Reducing harm from climate change is a challenging endeavor, and it requires comprehensive p.....»»
Grackle study finds behavior is the secret to success for a range expansion
While many species are undergoing drastic declines in their numbers and geographic ranges, other species seem to be thriving. Researchers investigating the great-tailed grackle, a bird that has been establishing new populations across North America i.....»»
Scientists call for a tree planting drive to help tackle heat waves
Adding more natural areas across our towns and cities could cool them by up to 6°C during heat waves, according to new research from the University of Surrey's Global Centre for Clean Air Research (GCARE)......»»
Researchers study the formation of cardenolides in plants
Scientists at the Max Planck Institute for Chemical Ecology in Jena are investigating the previously largely unknown biosynthetic pathway that leads to the formation of cardenolides in plants......»»
Researchers: If neutron stars have mountains, they should generate gravitational waves
A neutron star is 2 solar masses compressed into a ball only 12 kilometers wide. Its surface gravity is so immense it compresses atoms and molecules into raw nuclei and squeezes electrons into protons transforming them into neutrons. Given such immen.....»»
How climate assemblies can help Canada tackle the climate crisis
Canada's ongoing and record-breaking wildfire season and the recent heat waves around the world have galvanized Western public attention to the climate crisis like never before......»»
Researchers discover gravitational collapse and accretion flows in hub filament system G323.46-0.08
Hub-filament systems are ubiquitous in molecular clouds. Most dense clumps and cores are formed in filaments and play a key role in star formation process. Therefore, investigating hub-filament system is one of the best ways to understand high-mass s.....»»
Calcium acts as missing link to dead cell clean-up
Scientists have found that extracellular calcium mediates the activation of a membrane protein that waves the flag signaling cell death......»»
Heat, drought, fires threaten Lebanon"s northern forests
Heat waves, low rainfall and the threat of wildfires are compounding the woes of people in the forested north of Lebanon, a country where economic pain has long taken prominence over environmental concerns......»»
Addis Ababa faces growing climate change risks such as heat, drought and floods, study warns
Addis Ababa, Ethiopia's capital city, will likely face increased heat waves, droughts and severe flooding over the next 67 years. These changes will pose risks to public health and infrastructure. They'll also be felt most acutely by the city's most.....»»
NZ"s vital kelp forests are in peril from ocean warming—threatening the important species that rely on them
