Pandemic causing 'nearly insurmountable' education losses globally: UNICEF
School closures due to the COVID-19 pandemic have caused "nearly insurmountable" losses in education among children around the world, UNICEF said on Monday.
Seed production and recruitment of juvenile trees affect how trees are migrating due to climate change
A new study co-authored by Jonathan Myers, associate professor of biology in Arts & Sciences at Washington University in St. Louis, provides key insights into how and why tree populations migrate in response to climate change at the continental scale.
James Webb Space Telescope Reaches Final Destination 1 Million Miles From Earth
CAPE CANAVERAL, Fla. — The world’s biggest, most powerful space telescope reached its final destination 1 million miles from Earth on Monday, a month after it lifted off on a quest to behold the dawn of the universe.
The James Webb Space Telescope fired its rocket thrusters for nearly five minutes to go into orbit around the sun at its designated spot, and NASA confirmed the...

Genetic analyses helped identify a new cryptic shark species of the genus Squatina from the Western Atlantic Ocean.
How environment and genomes interact in plant development
- ScienceDaily
- 22/1/24 21:10
A new study could help to breed more resilient crops as well as shed light on mechanisms that play a critical role in plant growth. The study focuses on how phenotypic plasticity, or the way a given trait can differ as a result of environmental conditions, influences the growth of sorghum.
Undiagnosed autistic traits common among youths with substance use disorders, study finds

An estimated 20 percent of teens and young adults who seek treatment for addiction may have previously unrecognized social impairment characteristics of an autism spectrum disorder, a new study finds.
Extraordinary black hole found in neighboring galaxy
- ScienceDaily
- 22/1/24 21:10
At one hundred thousand solar masses, it is smaller than the black holes we have found at the centers of galaxies, but bigger than the black holes that are born when stars explode. This makes it one of the only confirmed intermediate-mass black holes, an object that has long been sought by astronomers.
Heat dome and other climate events have growing impact on mental health

- 22/1/24 21:10
Last summer's Western North American heat dome caused more than record-breaking temperature increases--rising anxiety about climate change is reported in a new study on the weather event's impact on our mental health.
Researchers provide insight into how the brain multitasks while walking
- ScienceDaily
- 22/1/24 21:10
New research turns the old idiom about not being able to walk and chew gum on its head. Scientists have shown that the healthy brain is able to multitask while walking without sacrificing how either activity is accomplished.
Women ages 35 and younger are 44% more likely to have an ischemic stroke than male peers
- ScienceDaily
- 22/1/24 21:10
Women ages 35 years and younger were 44% more likely to have an ischemic stroke (caused by blockages of blood vessels in the brain) than their male counterparts, according to a new review of more than a dozen international studies on sex differences in stroke occurrence. This gap narrows between the ages of 35 and 45, and there is conflicting evidence about whether women or men have more ischemic...
Forest emissions scheme makes 'tiny' contribution to Indonesia’s Paris targets
- ScienceDaily
- 22/1/24 21:10
More than 70 million tons of carbon were prevented from being released into the atmosphere under a deforestation emissions reduction scheme in Indonesia -- but researchers point out this is only 3 per cent of the total required by Indonesia's Nationally Defined Contribution (NDC) under the Paris Agreement.
Tapirs and large peccaries are key to ecological balance in Neotropical forests, study shows
A study conducted by researchers affiliated with São Paulo State University (UNESP) in Brazil shows that large mammals have a major impact on plant diversity, primary productivity and biomass in the understory of Neotropical forests. Species like the lowland tapir (Tapirus terrestris) and white-lipped peccary (Tayassu peccari) help keep an ecological balance in areas such as the Atlantic...
Extraordinary black hole found in neighboring galaxy
Astronomers have discovered a black hole unlike any other. At one hundred thousand solar masses, it is smaller than the black holes we have found at the centers of galaxies, but bigger than the black holes that are born when stars explode. This makes it one of the only confirmed intermediate-mass black holes, an object that has long been sought by astronomers.
Under the hood: How environment and genomes interact in plant development
Iowa State University scientists have harnessed data analytics to look "under the hood" of the mechanisms that determine how genetics and changing environmental conditions interact during crucial developmental stages of plants.
Forest emissions scheme makes 'tiny' contribution to Indonesia's Paris targets
More than 70 million tons of carbon were prevented from being released into the atmosphere under a deforestation emissions reduction scheme in Indonesia—but researchers point out this is only 3 percent of the total required by Indonesia's Nationally Defined Contribution (NDC) under the Paris Agreement.
New study calls into question the importance of meat eating in shaping our evolution
Quintessential human traits such as large brains first appear in Homo erectus nearly 2 million years ago. This evolutionary transition towards human-like traits is often linked to a major dietary shift involving greater meat consumption. A new study published today in the Proceedings of the National Academy of Sciences, however, calls into question the primacy of meat eating in early human...
Team demonstrates molecular electronics sensors on a semiconductor chip
The first molecular electronics chip has been developed, realizing a 50-year-old goal of integrating single molecules into circuits to achieve the ultimate scaling limits of Moore's Law. Developed by Roswell Biotechnologies and a multi-disciplinary team of leading academic scientists, the chip uses single molecules as universal sensor elements in a circuit to create a programmable biosensor with...
