When Daniella Chusy, currently at Indiana University, U.S., learned that many captive elephants were thought to be overweight and that their low birth rates suggested that they may be facing a fertility crisis, she began seeing parallels with the obesity crisis humans face currently. But no one had actually measured how much fat captive Asian elephants (Elephas maximus) in zoos carry. "I was...

After just a week in office, the Biden administration is already under immense public pressure to fix America’s mangled vaccine rollout. Operation Warp Speed injected enormous sums into developing vaccines but left most of the planning—and cost—of administering them to states, which are now having to cope with the fallout. The reliance on chronically underfunded…

Researchers used single-molecule imaging to compare the genome-editing tools CRISPR-Cas9 and TALEN. Their experiments revealed that TALEN is up to five times more efficient than CRISPR-Cas9 in parts of the genome, called heterochromatin, that are densely packed. Fragile X syndrome, sickle cell anemia, beta-thalassemia and other diseases are the result of genetic defects in the heterochromatin.

Much of the earth's carbon is trapped in soil, and scientists have assumed that potential climate-warming compounds would safely stay there for centuries. But new research from Princeton University shows that carbon molecules can potentially escape the soil much faster than previously thought. The findings suggest a key role for some types of soil bacteria, which can produce enzymes that break...

US President Joe Biden was planning to announce new bans on oil and gas drilling on federal lands Wednesday as part of a raft of actions that take aim at climate change, according to reports and a White House memo.

Indonesia's most active volcano erupted Wednesday with a river of lava and searing gas clouds flowing 1,600 meters (5,250 feet) down its slopes.

Harpy eagles are considered by many to be among the planet's most spectacular birds. They are also among its most elusive, generally avoiding areas disturbed by human activity—therefore already having vanished from portions of its range—and listed by the International Union for the Conservation of Nature (IUCN) as being 'Near-Threatened'.

Multi-disciplinary researchers at The University of Manchester have helped develop a powerful physics-based tool to map the pace of language development and human innovation over thousands of years—even stretching into pre-history before records were kept.

The United States Department of Agriculture identifies a group of "big eight" foods that causes 90% of food allergies. Among these foods are wheat and peanuts.

A material that can be used in technologies such as solar power has been found to self-heal, a new study shows.

Like Einstein, Galileo, and Copernicus, former NASA program manager Craig Tooley now has a place on the Moon named in his honor. Tooley crater is a 7 km crater in a permanently shadowed region of Shoemaker crater near the lunar south pole. The new crater designation is official and can be used in journal articles and other publications.

The results of the Peoples' Climate Vote, the world's biggest ever survey of public opinion on climate change are published today. Covering 50 countries with over half of the world's population, the survey includes over half a million people under the age of 18, a key constituency on climate change that is typically unable to vote yet in regular elections. 

Should I worry about my addiction to 1,000-piece brainteasers? Not according to the scientistsIf you looked at my Google search history (which I would obviously never let anyone do), an alarming percentage of it would consist of variations of: “Is X actually good for you?” With X being whichever bad habit I’m engaged in. The amazing thing about the internet is that you can always find a...

More than a million people in 50 countries take part in the biggest poll to date on climate change.

A research team led by University of Tsukuba has produced genome sequences for two wild species of tomato from South America, ancestors of the cultivated tomato. The ancestral species contain thousands of genes that are not present in modern types. The novel genes will help plant breeders produce new tomatoes with features like improved disease resistance, increased tolerance for the changing...

Wildfires are the enemy when they threaten homes in California and elsewhere. But a new study led by SMU suggests that people living in fire-prone places can learn to manage fire as an ally to prevent dangerous blazes, just like people who lived nearly 1,000 years ago.

Got milk? The 1990s ad campaign highlighted the importance of milk for health and wellbeing, but when did we start drinking the milk of other animals? And how did the practice spread? A new study led by scientists from Germany and Kenya highlights the critical role of Africa in the story of dairying, showing that communities there were drinking milk by at least 6,000 years ago.

Much of the earth's carbon is trapped in soil, and scientists have assumed that potential climate-warming compounds would safely stay there for centuries. But new research from Princeton University shows that carbon molecules can potentially escape the soil much faster than previously thought. The findings suggest a key role for some types of soil bacteria, which can produce enzymes that break...

Children of all ages can completely bypass age verification measures to sign-up to the world's most popular social media apps including Snapchat, Instagram, TikTok, Facebook, WhatsApp, Messenger, Skype and Discord by simply lying about their age, researchers at Lero, the Science Foundation Ireland Research Centre for Software have found.

In a small study, stroke survivors who completed a three-month cardiac rehabilitation program focused on aerobic exercise significantly improved their physical endurance and strength.Six months after the program more, 83.3% of participants reported that they continued exercising at least once a week.

Researchers used single-molecule imaging to compare the genome-editing tools CRISPR-Cas9 and TALEN. Their experiments revealed that TALEN is up to five times more efficient than CRISPR-Cas9 in parts of the genome, called heterochromatin, that are densely packed. Fragile X syndrome, sickle cell anemia, beta-thalassemia and other diseases are the result of genetic defects in the heterochromatin.

New research led by the University of Plymouth (UK) suggests estimates of the species' current distribution are potentially overestimating range size.

Heart disease remains the #1 cause of death worldwide in the latest annual Statistical Update from the American Heart AssociationExperts say the effects of COVID-19 are likely to influence cardiovascular health and mortality rates for many years, directly and as a result of increased lifestyle-related risks during and after the pandemic.

A characteristic feature of all stem cells is their ability to self-renew. But how is this potential maintained throughout life? Scientists at the German Cancer Research Center (DKFZ) and the Heidelberg Institute for Stem Cell Technology and Experimental Medicine* (HI-STEM) have now discovered in mice that cells in the so-called "stem cell niche" are responsible for this,

Research uses plant breeding and biotechnology to remove proteins associated with food allergies.

A physics professor has joined forces with language experts to build a 'linguistic thermometer' that can record the temperature of 'hot' or 'cold' (ie fast or slow) developments in modern linguistic features to create a computer-based model that can provide a better understanding of the development in human language and innovation stretching back to pre-history.

Study explores lateralization changes in resting state brain network functional connectivity. Among military service members and Veterans with symptoms of traumatic stress, asymmetries of network and brain region connectivity patterns were identified prior to usage of HIRREM. A variety of changes in lateralized patterns of brain connectivity were identified post intervention. These laterality...

When severely or chronically injured, the liver loses its ability to regenerate. A new study led by researchers at the Center for Regenerative Medicine at Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) now describes a safe new potential therapeutic tool for the recovery of liver function in chronic and acute liver diseases.

Taking cannabidiol, a chemical in the cannabis sativa plant, isn't an effective way to reduce your dependence on cocaine, researchers at the CHUM Research Centre find.

An innovative UNDP global survey conducted in collaboration with Oxford University experts -- the largest-ever opinion survey on climate change (1.2 million people in 50 countries) -- finds 64% ( 2%) deem climate an 'emergency.' Worldwide, most people clearly want a strong and wide-ranging policy response, and 4 of 18 policy options received majority support.Distributed across mobile gaming...

President Biden has cancelled the permit for the controversial US-Canada project.

Francisco Vera, 11, was threatened after calling for better access to education during the pandemic.

Our cells are filled with 'bones,' in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, actin filaments constantly grow, shrink, bind with other things, and branch off when cells move.

Heart disease is a killer threat for southern sea otters feasting on domoic acid in their food web, according to a study led by the University of California, Davis.

Burning fossil fuels has long powered world economies while contributing to air pollution and the buildup of greenhouse gases. A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to Penn State scientists.

A team of marine scientists led by the Wildlife Conservation Society (WCS) has confirmed that southern Africa's most threatened endemic shark—the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) - has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).

Black holes are considered amongst the most mysterious objects in the universe. Part of their intrigue arises from the fact that they are actually among the simplest solutions to Einstein's field equations of general relativity. In fact, black holes can be fully characterized by only three physical quantities: their mass, spin and charge. Since they have no additional "hairy" attributes to...
