Europe faces ‘cancer epidemic’ after estimated 1m cases missed during Covid
Armadillos stash a secret under their shells—their liver grows dramatically when they are infected with the bacterium that causes leprosy in people. This oddity, revealed in a new study, may provide clues about how the body controls liver regeneration and how to jump-start the process in people.
The finding is “very cool,” says hepatologist Alejandro Soto-Gutiérrez of the...
Nigeria has too many prison inmates awaiting trial—technology could achieve swifter justice
Report says 100m screenings lost because of pandemic, which had ‘chilling effect’ on researchExperts have warned that Europe faces a “cancer epidemic” unless urgent action is taken to boost treatment and research, after an estimated 1m diagnoses were missed during the pandemic.The impact of Covid-19 and the focus on it has exposed “weaknesses” in cancer health systems and in the cancer...
Global climate finance leaves out cities: Fixing it is critical to battling climate change
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.
Opinion: Why COP27 should be the last of these pointless corporate love-ins
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.
In new book, doctor sees humanity devouring itself and the planet
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.
Rockets to Uncover Electric Circuit That Powers the Northern Lights
"At the moment," writes Warren Hern, "we are the most misnamed species on the planet: Homo sapiens sapiens—'wise, wise man.' Not."

UK polar research ship to make 2nd voyage to Antarctica
In a rare piece of good news in the marine world, scientists have found one place where reef manta rays are thriving.
How NASA's Deep Space Network supports the agency's missions
Britain's polar research ship is preparing for its second voyage to Antarctica to investigate sea level rises and threats to marine biodiversity.
Researchers use random numbers to precisely describe the warm dense hydrogen found in some planet interiors
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...
Government can minimize racial inequality in criminal justice by reducing police stops, detention, and long sentences
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.
Footprints claimed as evidence of ice age humans in North America need better dating, new research claims
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.
Emergent bilinguals lost vital instruction during remote learning, study shows
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...
Researchers ready for a new space mission to shed light on Brazil's vexing GPS problem
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.
Little objective evidence to show effectiveness of learner-centered teaching methods, study warns
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.
Health harms of mass shootings ripple across communities
There is currently relatively little objective evidence that the much-promoted "learner-centered" approach to teaching is effective, according to new research.
Word choice and media exposure affected anti-Asian boycotts during the pandemic, study finds
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.
New discoveries made about a promising solar cell material, thanks to new microscope
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 gene from 28 million years ago protects today's plants against caterpillars
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.
