Reforestation projects should include a variety of tree species and ensure genetic diversity within each species to maximize new forests' health and productivity, suggests a study published today in eLife.
The 1930s Dust Bowl affected heat extremes across much of North America and as far away as Europe and East Asia, according to new research. The study found that the extreme heating of the Great Plains triggered motions of air around the Northern Hemisphere in ways that suppressed cloud formation in some regions and contributed to record heat thousands of miles away.
A new study reveals that the relationship between work demands and a good night's rest is nuanced. Conventional wisdom that suggests that people with the most demanding jobs would have the most trouble sleeping isn't necessarily true.
About one third of patients with diabetes mellitus (DM) develop diabetic retinopathy (DR), a leading cause of blindness in working-age individuals. DR typically develops after many years of DM, and some patients do not develop DR for more than 50 years. New research suggests that an endogenous system that protects human retinal endothelial cells from harmful effects of the hyperglycemia (an excess...
How picky should females and males be when they choose a mate? How fiercely should they compete for mates? And how much should they engage in raising their offspring? The answers to these questions largely depend on the ratio of adult females to males in the social group, population or species.
New research yields a novel method to use ultrasound to enhance machine learning's ability to accurately diagnose -- or rule out -- ovarian cancer.
Researchers are introducing a better way to perform mosquito-tracking for disease applications. Their new method, which involves getting larval mosquitoes to eat harmless particles made entirely of DNA and proteins, has the potential to revolutionize how people study mosquito-borne diseases.
Unique new material has shown significant promise in the treatment of spinal cord injury. The new hybrid biomaterials, in the form of nanoparticles and building on existing practice in the tissue engineering field, were successfully synthesized to promote repair and regeneration following spinal cord injury, according to the researchers.
While a lot of attention has been given to the unprecedented protests in China about the "dynamic zero COVID" policy, not much has been written about the wider political context, and particularly the young people leading the protests.
A naturally occurring virus co-discovered by Agricultural Research Service (ARS) and university scientists may offer a way to undermine a costly fungal threat to wheat, barley and other small-grain crops.
Sharks have reputations as "super smellers" that use olfaction to detect odors related to finding prey and mates, communicating with their own species and avoiding predators. Their olfactory system is unique because it is separate from the respiratory system, unlike humans. Sharks and other fish use gills to facilitate the uptake of oxygen, while two nares or nostrils on the shark's head take in...
The economic impact of COVID on Pacific Island states, combined with major labor shortages in Australia and New Zealand, has created a perfect storm. A mass exodus means Pacific nations are now losing crucial workers at such volume that their own development prospects are being undermined.
In the seven years since the Independent Inquiry into Child Sexual Abuse launched in 2015, it has held more than 300 days of public hearings, processed over 2 million pages of evidence, heard from over 700 witnesses, and engaged with over 7,000 victims and survivors.
Most Australian book authors do not earn enough income from their creative practice to make ends meet. They rely on other jobs and other support, such as a partner's income.
The Wadden Sea is an extremely productive ecosystem whose food web is supported by benthic organisms, feeding on primary producers. In a recent publication in Frontiers in Ecology and Evolution, NIOZ marine biogeochemist dr. Philip Riekenberg and colleagues show where (part of) this exceptional productivity may come from.
A newly released report on the status of wild species in Canada has cataloged more species than any previous report — roughly 50,000 — and warns more than 2,000 of them face a high risk of being wiped out in the...
Only about one in three Americans have enough saved for retirement, according to a national survey. But new research from the University of Georgia offers what might be a silver lining to the doom and gloom: Generation X doesn't appear any worse off than the baby boomers.
UK households, like those in many other countries, are struggling to make ends meet. More than half of households have only £2.66 per week left after paying for bills and essentials, according to figures from the supermarket chain Asda.
The world is under growing pressure to find sustainable options to cut emissions or lessen the impacts of climate change.
The World Meteorological Organization has published its first State of Global Water Resources report in order to assess the effects of climate, environmental and societal change on the Earth's water resources. The aim of this annual stocktake is to support monitoring and management of global freshwater resources in an era of growing demand and limited supplies.
Waves of orange, glowing lava and ash blasted and billowed from the world's largest active volcano in its first eruption in 38 years, and officials told people living on Hawaii's Big Island to be ready in the event of a worst-case scenario.
A new report from Heriot-Watt University, and Matt Rayment from ICF, has outlined a range of findings highlighting the benefits and challenges of scaling the "Housing First" approach to address homelessness in Scotland.
Surrey's Global Center for Clean Air Research (GCARE) found that campaigns aimed at changing the behavior of parents, teachers and the local community can reduce outdoor nitrogen dioxide exposure by up to 23% compared to business-as-usual activities. However, the study's authors believe behavioral change campaigns should be more inclusive and should consider the school's diverse communities and...
Skateboarding continues to be unkempt, subversive and tacitly political despite inclusion in mainstream competitions like the Olympics, experts have said.
"Future chips may be 10 times faster, all thanks to graphene"; "Graphene may be used in COVID-19 detection"; and "Graphene allows batteries to charge 5x faster"—those are just a handful of recent dramatic headlines lauding the possibilities of graphene. Graphene is an incredibly light, strong and durable material made of a single layer of carbon atoms. With these properties, it is no wonder...
