Natural exposure to wildfire smoke increased pregnancy loss in rhesus macaques
Rhesus macaques naturally exposed to wildfire smoke early in pregnancy had an increased rate of miscarriage, according to new research from the California National Primate Research Center at the University of California, Davis. The work is published online in the journal Reproductive Toxicology.
Forest fires linked to tens of thousands of avoidable deaths
Setting fire to forest and agricultural land in Southeast Asia to prepare it for cultivation or grazing contributes to an estimated 59,000 premature deaths a year, say scientists.
Researcher seeks to mitigate natural hazards with vulnerability in mind
From tropical storms to landslides, the form and frequency of natural hazards vary widely. But the feelings of vulnerability they can provoke are universal.
Diverse landcover boosts yields for major U.S. crops, study finds
Monoculture—or specializing in a single crop, covering larger fields that can be harvested with bigger machines on a simplified landscape—is widely assumed to boost a farm's production capacity. A major study encompassing the mainland United States, however, suggests that the opposite is true. Nature Food published the research.
Wing shape determines how far birds disperse
Bird dispersal movements are thought to depend on complex demographic and genetic factors. Dr. Santiago Claramunt, Associate Curator of Birds at the Royal Ontario Museum (ROM) and Assistant Professor in the Department of Ecology and Evolutionary Biology of the University of Toronto, shows that there may be a simpler explanation: bird dispersal distances depend on the morphology and flight...
NASA works to give satellite swarms a hive mind
Swarms of small satellites could communicate amongst themselves to collect data on important weather patterns at different times of the day or year, and from multiple angles. Such swarms, using machine learning algorithms, could revolutionize scientists' understanding of weather and climate changes.
Examining asteroid Ryugu in opposition to Hayabusa2: A starkly lit distribution of dust and rock
New analysis of Hayabusa2 data of the asteroid Ryugu reveals much of the surface reflects and scatters light in ways that are consistent with studies of carbonaceous chondrite meteorites in the lab. This research looks specifically at data taken while Ryugu was in opposition to the spacecraft and Sun, and utilizes Hayabusa2's near infrared spectrometer, NIRS3, and Optical Navigation Camera, ONC,...
Indian wolf among world's most endangered and distinct wolves
The Indian wolf could be far more endangered than previously recognized, according to a study from the University of California, Davis, and the scientists who sequenced the Indian wolf's genome for the first time.
EXPLAINER: How Ida can be so deadly 1000 miles from landfall
Natural and some man-made ingredients came together, causing the weakened but still soggy remnants of Hurricane Ida to devastate the Northeast more than 1,000 miles (1,600 kilometers) away from its landfall.
NASA's newest Mars rover snags 1st rock sample for return
NASA's newest Mars rover has successfully collected its first rock sample for return to Earth, after last month's attempt came up empty.
Changing winds provide hope for California wildfire battle
Better weather on Thursday helped the battle against a huge California forest fire threatening communities around Lake Tahoe, but commanders warned firefighters to be prepared for dangers that still pose a risk.
US grounds Virgin Galactic after space flight 'mishap'
The US Federal Aviation Administration (FAA) on Thursday said it was grounding space flights by Virgin Galactic while it investigates why the company's July mission carrying Richard Branson deviated from its planned trajectory.
'Heartbroken' New Yorkers count cost of devastating rainfall
New Yorkers mopped up flooded homes and businesses and began removing fallen debris from crushed cars Thursday as they counted the cost of record rainfall that caught much of the Big Apple by surprise.
Putting a new theory of many-particle quantum systems to the test
New experiments using trapped one-dimensional gases—atoms cooled to the coldest temperatures in the universe and confined so that they can only move in a line—fit with the predictions of the recently developed theory of "generalized hydrodynamics." Quantum mechanics is necessary to describe the novel properties of these gases. Achieving a better understanding of how such systems with many...
Entrepreneurs crucial for UK's recovery from COVID and dealing with Brexit economic fallout, says report
As in previous economic downturns, it is the small business community that drives the recovery across all sectors of the economy. UK entrepreneurs once again stand ready to rise to the challenges and opportunities created by the Coronavirus pandemic and the economic fallout from Brexit, a new report says.
Researchers sequence genome of drug-resistant Salmonella enteritidis strain that can sicken poultry
Researchers from North Carolina State University have sequenced the genome of a virulent Salmonella Enteritidis strain that sickened two poultry flocks in consecutive years and found that it was both antibiotic resistant and could potentially infect humans. Characterizing the strain, designated SE_TAU19, will aid public health agencies in tracing outbreaks and preventing exposures.
Do we need an IPCC for food?
The first United Nations Food Systems Summit (UNFSS), scheduled for September, could be as historic to food system transformation as the Rio Earth Summit of 1992 was to climate change. Rio sparked the creation of the Intergovernmental Panel on Climate Change, or IPCC, which has brought scientists and governments around the world together and has greatly increased consensus and understanding of the...
Cavalier King Charles spaniels carry more harmful genetic variants than other breeds
Recent dog breeding practices have loaded up cavalier King Charles spaniels with disease-causing mutations, including variants linked to the common heart condition, myxomatous mitral valve disease (MMVD). Erik Axelsson of Uppsala University and colleagues published these new findings September 2nd in the journal PLOS Genetics.
A surprise result for solid state physicists hints at an unusual electron behavior
While studying the behavior of electrons in iron-based superconducting materials, researchers at the University of Tokyo observed a strange signal relating to the way electrons are arranged. The signal implies a new arrangement of electrons the researchers call a nematicity wave, and they hope to collaborate with theoretical physicists to better understand it. The nematicity wave could help...
Study reveals extreme winter weather is related to Arctic change
A new study shows that the frequency of polar vortex disruptions that is most favorable for extreme winter weather in the United States is increasing, and that Arctic change is likely contributing to the increasing trend. Led by Atmospheric and Environmental Research (AER), University Massachusetts Lowell and the Hebrew University of Jerusalem, the study is published in the September 3 issue of...
Stellar collision triggers supernova explosion
Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from the Very Large Array Sky Survey (VLASS), a multi-year project using the National Science Foundation's Karl G. Jansky Very Large Array (VLA).
High hopes for lowly pond scum
Pond scum generally isn't looked upon kindly. But the microalgae that make up these floating green mats of slime could get newfound respect as renewable sources of fuel, specialty chemicals, dietary supplements and other valued products.
Researchers identify the biosynthesis of carthamin, the historic red colorant in safflowers
Carthamin is a red pigment that stems from the yellow-orange corollas of safflower. Its usage as a red colorant can be traced back to ancient Egypt. In Japan it is named "beni" and has been used for dyeing textiles, coloring cosmetics and food, and as an herbal medicine for over 1400 years.
Hurricane Ida 'may be one of the best observed landfalling hurricanes'
A research team led by Michael Biggerstaff, a professor of meteorology in the College of Atmospheric and Geographic Sciences at the University of Oklahoma, successfully captured data with mobile radars and other weather instruments as Hurricane Ida made landfall in Louisiana.
