What do criminal justice risk assessments actually assess?
Exposure to the criminal justice system increases some of the risk factors used to predict recidivism and re-arrest, according to new research out of Columbia University Mailman School of Public Health. For every arrest or conviction an adolescent experienced, their levels of antisocial attitudes, behaviors, and number of peers became subsequently higher. Findings provide new empirical evidence...
Cracking a decades-old test, researchers bolster case for quantum mechanics
In a new study, researchers demonstrate creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics. With their innovative method, the researchers were able to demonstrate quantum interactions between two particles spaced more than 180 meters (590 feet) apart while eliminating the possibility that shared events during the past 11 years affected their interaction.
Nano-thermometer takes temperature inside cells
How do you know a cell has a fever? Take its temperature.
What's killing sea otters? Scientists pinpoint parasite strain
Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A study from the University of California, Davis, identifies the parasite's specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from...
How red-eared invaders are hurting California's native turtles
In the summer of 2011, visitors to the University of California, Davis, Arboretum may have witnessed an unusual site: small teams of students wielding large nets, leaping into the arboretum's waterway to snag basking turtles.
New images from asteroid probe offer clues on planet formation
Photographs snapped by a shoebox-sized probe that explored the near-Earth asteroid Ryugu have offered new clues about its composition, insights that will help scientists understand the formation of our solar system.
San Francisco Zoo brings red-legged frogs back to Yosemite
A healthy population of red-legged frogs is hopping in Yosemite National Park, helped by a reintroduction program with the San Francisco Zoo.
Amazon fires stir bitter dispute over who is to blame
As fires raged in the Amazon rainforest, the Brazilian government on Thursday denounced international critics who say President Jair Bolsonaro is not doing enough to curb massive deforestation.
NASA's aqua satellite finds a weaker Chantal, now a depression
Over the last day, winds outside of Tropical Storm Chantal have been weakening the storm in the North Atlantic Ocean. When NASA's Aqua satellite passed over the storm from its orbit in space on August 22, the storm had weakened to a depression and strongest storms were still confined to the northeast of the center.
Biomaterials smarten up with CRISPR
The CRISPR-Cas system has become the go-to tool for researchers who study genes in an ever-growing list of organisms, and is being used to develop new gene therapies that potentially can correct a defect at a single nucleotide position of the vast reaches of the genome. It is also being harnessed in ongoing diagnostic approaches for the detection of pathogens and disease-causing mutations in...
The case for retreat in the battle against climate change
When it comes to climate change, moving people and development away from at-risk areas can be viewed, not as a defeat, but as a smart strategy that allows communities to adapt and thrive.
New tool mines scientific texts for fusion protein facts
A new computational tool called ProtFus screens scientific literature to validate predictions about the activity of fusion proteins—proteins encoded by the joining of two genes that previously encoded two separate proteins. Somnath Tagore in the Frenkel-Morgenstern Lab at Bar-Ilan University, Israel, and colleagues present ProtFus in PLOS Computational Biology.
Structure of protein nanoturbine revealed
Cells rely on protein complexes known as ATP synthases or ATPases for their energy needs. Adenosine triphosphate (ATP) molecules power most of the processes sustaining life. Structural biologist Professor Leonid Sazanov and his research group from the Institute of Science and Technology Austria (IST Austria) in Klosterneuburg, Austria have now determined the first atomic structure of the...
Map of malaria behavior set to revolutionize research
The first detailed map of individual malaria parasite behaviour across each stage of its complicated life cycle has been created by scientists. Researchers at the Wellcome Sanger Institute and their collaborators used advanced single-cell technology to isolate individual parasites and measure their gene activity. The result is the Malaria Cell Atlas, which gives the highest resolution view of...
Experiments illuminate key component of plants' immune systems
Plants, like humans and animals, have over millions of years evolved complex immune systems that fend off invading pathogens. But unlike many animals, plants lack adaptive immunity conferred by antibodies. This means each plant cell must defend itself against all potential pathogens—a daunting task.
Cell suicide could hold key for brain health and food security
Research into the self-destruction of cells in humans and plants could lead to treatments for neurodegenerative brain diseases and the development of disease-resistant plants.
Scientists successfully innoculate, grow crops in salt-damaged soil
A group of researchers may have found a way to reverse falling crop yields caused by increasingly salty farmlands throughout the world.
US environmental groups sue over wildlife protection rollbacks
US environmental groups have sued the administration of President Donald Trump over rollbacks that weaken the Endangered Species Act, a law credited with saving iconic species from the bald eagle to the grizzly bear.
Tracing the evolution of vision in fruit flies
The function of the visual photopigment rhodopsin and its action in the retina to facilitate vision is well understood. However, there remain questions about other biological functions of this family of proteins (opsins) and this has ramifications for our understanding of several evolutionary pathways. Now, an international research team led by the University of Göttingen has shown there are...
Storms on Jupiter are disturbing the planet's colorful belts
Storm clouds rooted deep in Jupiter's atmosphere are affecting the planet's white zones and colorful belts, creating disturbances in their flow and even changing their color.
Adaptation to life inside cattle may be driving E. coli to develop harmful features
A large-scale study of the genetic differences and similarities among E. coli bacteria from cattle and humans indicates that features causing food poisoning in humans may continuously be emerging in bacteria from cattle as a means to better adapt to their environment.
Florida's oysters in Apalachicola, Cedar Key face climate threats to survival
Climate change isn't a primary suspect in the stunning extermination of Apalachicola Bay oysters, a calamity pegged to a variety of atrocities.
A law just for Trump's presidency? California measure aims to protect state's environment
California is considering a far-reaching law that would lock current environmental protections into place and would only be in effect until the end of Donald Trump's presidency.
Mexican marijuana traffickers are poisoning California forests with a banned pesticide, officials say
California law enforcement has learned that Mexican drug traffickers are using a dangerous pesticide banned in the United States to grow marijuana in remote areas of California's Sierra Nevada mountains, and are going after their operations.
New study reveals carbon nanotubes measurement possible for the first time
Swansea University scientists have reported a new approach to measuring the conductivity between identical carbon nanotubes which could be used to help improve the efficiency of electrical power cables in the future.
