Nigeria's prison population is more than 76,000, housed in 240 correctional centers. About 70% of these inmates are still awaiting trial. They have been arrested and charged, but not yet convicted or cleared.

Under the Paris Agreement, which came into force in 2016, countries agreed to reduce their greenhouse gas emissions and work together to adapt to the effects of climate change. To act on this, and codify their individual commitments, each country submitted its so-called Nationally Determined Contribution.

It's a glorious afternoon at a luxury resort in Egypt, with six swimming pools leading to a lovely little stretch of beach on the Red Sea. A salsa aquatic class in one of the pools has several enthusiastic participants. Elsewhere, guests are lounging on deck chairs sipping ice cold cocktails. Cheerful waiters are refilling glasses and serving snacks.

"At the moment," writes Warren Hern, "we are the most misnamed species on the planet: Homo sapiens sapiens—'wise, wise man.' Not."

In a rare piece of good news in the marine world, scientists have found one place where reef manta rays are thriving.

Britain's polar research ship is preparing for its second voyage to Antarctica to investigate sea level rises and threats to marine biodiversity.

Over 50 years ago, NASA captured the world's imagination and inspired generations with the Apollo 11 moon landing. NASA's then-young Deep Space Network (DSN) was crucial to tracking and communicating with that mission, as it will also be essential to NASA's next push to the moon: Artemis. In the half-century between those two lunar efforts, the network has expanded to support dozens of robotic...

Discovering the properties of quantum systems that are made of many interacting particles is still a huge challenge. While the underlying mathematical equations have been long known, they are too complex to be solved in practice. Breaking that barrier most probably would lead to a plethora of new findings and applications in physics, chemistry and the material sciences.

To reduce racial inequality in the U.S. criminal justice system, local, state, and federal government should explore ways to reduce police stops and searches, jail detention, prison admission, and long sentences, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The wide expanse of an ancient lakebed in New Mexico holds the preserved footprints of life that roamed millennia ago. Giant sloths and mammoths left their mark, and alongside them, signs of our human ancestors. Research published in September 2021 claimed that these footprints are "definitive evidence of human occupation of North America" during the last ice age, dating back to between 23,000 and...

Emergent bilingual learners—students developing proficiency in English and another language—in kindergarten through second grade saw significant loss of language-rich instruction during remote learning caused by the COVID-19 pandemic, according to a study by Amy Crosson, associate professor of education in the Penn State College of Education.

In certain regions of Brazil, don't be surprised if your GPS device behaves erratically. For years, researchers have been scratching their heads, looking for a solution to the unreliable GPS signals in regions near the Amazon. The cause? Plasma bubbles in space.

There is currently relatively little objective evidence that the much-promoted "learner-centered" approach to teaching is effective, according to new research.

A grim and familiar pattern has followed the parade of mass shootings across America. In their aftermath, the nation's attention focuses on the direct victims of the attacks, the dead and injured, their families and friends, and the witnesses.

During 2020, the use of terms like the "China virus" by public officials and in the media negatively connected COVID-19 to China, where the virus originated, causing a detrimental impact. New research from scholars of the hospitality industry at Penn State and the University of Houston found that this type of virus naming contributed to hostility toward and boycotting of Chinese restaurants and...

A team of scientists from the Department of Energy's Ames National Laboratory has developed a new characterization tool that allowed them to gain unique insight into a possible alternative material for solar cells. Under the leadership of Jigang Wang, senior scientist from Ames Lab, the team developed a microscope that uses terahertz waves to collect data on material samples. The team then used...

The defense mechanisms plants use to recognize and respond to a common pest—the caterpillar—has arisen from a single gene that evolved over millions of years, according to a report published today in eLife.

New University of Minnesota research suggests that while many in the midst of divorce struggle at work, others find renewed career motivation.

A team of researchers from the Group of Neural Circuit in the Graduate School of Science at Nagoya University in central Japan have developed a new method that may help control mosquito populations. The annoying buzzing sound that mosquitoes make when flying inspired this technique.

Layered double hydroxides (LDHs) have a unique structure and many benefits, which have led to them being widely used in fields such as catalysis, environmental management and medical applications. Typically, soluble metal salts, such as metal nitrates, are used as the starting materials for the synthesis of LDHs, but they are relatively expensive and can be inconvenient to store and transport due...

Unlike humans, turtles, lizards and other reptiles—such as crocodiles—do not have sex chromosomes. Their sex is determined based on the environment, which makes them especially vulnerable to climate change. An increase in incubation temperatures could jeopardize the production of both sexes.

Just a few hundred feet from where we are sitting is a large metal chamber devoid of air and draped with the wires needed to control the instruments inside. A beam of particles passes through the interior of the chamber silently at around half the speed of light until it smashes into a solid piece of material, resulting in a burst of rare isotopes.

NASA is kicking off its new moon program with a test flight of a brand-new rocket and capsule.

Even though it is over 2,000 years since the ancient Roman road networks were established, there are clear connections between the routes of the roads and modern-day prosperity. In a study in economics, the researchers investigate the importance of the Roman road network in maintaining or losing wealth through the centuries.
