NASA releases 'amazing' new landing video and images from Mars Perseverance landing
It was "seven minutes of terror" that had a big payoff: NASA's Mars Perseverance safely landed on the surface of the red planet last Thursday. And, for the first time, the edge-of-your-seat descent was captured by high-definition video cameras that NASA released on...
NASA's Mars Perseverance rover provides front-row seat to landing, first audio recording of Red Planet

New video from NASA's Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars.
Environmental policies not always bad for business, study finds
Critics claim environmental regulations hurt productivity and profits, but the reality is more nuanced, according to an analysis of environmental policies in China by a pair of Cornell economists.
Research delineates the impacts of climate warming on microbial network interactions
Climate change impacts are broad and far reaching. A new study by University of Oklahoma researchers from the Institute for Environmental Genomics explores the impacts of climate warming on microbial network complexity and stability, providing critical insights to ecosystem management and for projecting ecological consequences of future climate warming.
Polymer film protects from electromagnetic radiation, signal interference
As electronic devices saturate all corners of public and personal life, engineers are scrambling to find lightweight, mechanically stable, flexible, and easily manufactured materials that can shield humans from excessive electromagnetic radiation as well as prevent electronic devices from interfering with each other.
B.C. farmer grabs lynx by scruff of neck, scolds it for killing chickens
A farmer in northern B.C. captured a wild cat he found in his chicken coop Sunday, picking it up by the scruff of the neck and gently scolding it before relocating it to the...
Researchers challenge the CRP status quo to mitigate fossil fuels
Researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) found that transitioning land enrolled in the Conservation Reserve Program (CRP) to bioenergy agriculture can be advantageous for American landowners, the government, and the environment.
Big galaxies steal star-forming gas from their smaller neighbours
Large galaxies are known to strip the gas that occupies the space between the stars of smaller satellite galaxies.
Graphene oxide membranes could reduce paper industry energy costs
The U.S. pulp and paper industry uses large quantities of water to produce cellulose pulp from trees. The water leaving the pulping process contains a number of organic byproducts and inorganic chemicals. To reuse the water and the chemicals, paper mills rely on steam-fed evaporators that boil up the water and separate it from the chemicals.
How outdoor pollution affects indoor air quality
Just when you thought you could head indoors to be safe from the air pollution that plagues the Salt Lake Valley, new research shows that elevated air pollution events, like horror movie villains, claw their way into indoor spaces. The research, conducted in conjunction with the Utah Division of Facilities Construction and Management, is published in Science of the Total Environment.
Stem cells provide hope for dwindling wildlife populations
A paper recently published in the scientific journal Stem Cells and Development shares an important advancement in conservation—one that may make the difference between survival and extinction for wildlife species that have been reduced to very small population sizes. Using fibroblast cells that have been preserved in San Diego Zoo Global's Frozen Zoo, scientists have been able to generate...
Campaign promises more likely to be kept by governments run by women, research shows
Governments with strong female representation are more likely to deliver on campaign promises, according to new research from Rice University.
Lack of symmetry in qubits can't fix errors in quantum computing, might explain matter/antimatter
A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to operate properly—found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of matter and antimatter in...
Researchers create 'beautiful marriage' of quantum enemies
Cornell University scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics.

If depression is making it more difficult for some unemployed people to land a job, one type of therapy may help, research suggests. In a new study, 41% of unemployed or underemployed people undergoing cognitive behavioral therapy (CBT) found a new job or went from part- to full-time work by the end of the 16-week treatment for depression.
For Black Americans, Covid-19 is a reminder of the racism of US healthcare | Keon L Gilbert, Ruqaiijah Yearby, Amber Johnson and Kira Banks
A disproportionate number of the 500,000 Americans who have died of coronavirus are people of colorFor Black Americans, Covid-19 is another brutal reminder of the racist legacy of the American healthcare system. A disproportionate number of the 500,000 Americans who have died of coronavirus are Black. Yet African Americans and other people of color have struggled to access vaccines.Racism corrupts...
