Biden’s plan to tap former North Carolina health chief as CDC director wins praise
When the CRISPR gene editor landed in U.S. plant science labs a decade ago, allowing researchers to tweak a crop’s own DNA instead of pasting in foreign genes, hopes rose that it would pave the way for looser regulation of genetically modified crops. Last year, the U.S. Department of Agriculture (USDA) gave plant scientists much of their wish, exempting certain gene-edited changes to...
First-of-its-kind Mars livestream by ESA spacecraft interrupted at times by rain on Earth
Public health advocates today applauded the news that President Joe Biden intends to name Mandy Cohen, a physician and public health expert with broad government experience, to lead the U.S. Centers for Disease Control and Prevention (CDC).
Biden will appoint Cohen by the end of the month to replace current CDC Director Rochelle Walensky, who will step down on 30 June,...
Thousands ordered to flee advancing wildfires in Quebec
A European spacecraft around Mars sent its first livestream from the red planet to Earth on Friday to mark the 20th anniversary of its launch, but rain in Spain interfered at times.
Discovery challenges 30-year-old dogma in associative polymers research
Some 10,000 people on Friday were ordered to evacuate from a city in the Canadian province of Quebec in the face of advancing wildfires, officials said.
AI software can provide 'roadmap' for biological discoveries
A University of Virginia-led study about a class of materials called associative polymers appears to challenge a long-held understanding of how the materials, which have unique self-healing and flow properties, function at the molecular level.
Self-driving cars know the rules of the road — but not rules of humanity
Predicting a protein's location within a cell can help researchers unlock a plethora of biological information that's critical for developing future scientific discoveries related to drug development and treating diseases like epilepsy. That's because proteins are the body's "workhorses," largely responsible for most cellular functions.
New study finds strengthening protection of existing parks is crucial for biodiversity conservation
When it comes to reading cues from human drivers, autonomous vehicles have a ways to...
Improving fluid simulations with embedded neural networks
In a new study, bioscientists argue that strengthening the protection given to areas already protected under law or by local communities is as critical for safeguarding biodiversity as creating new protected areas.
Predicting the composition of a steel alloy
While neural networks can help to improve the accuracy of fluid flow simulations, new research shows how their accuracy is limited unless the right approach is taken. By embedding fluid properties into neural networks, simulation accuracy can improve by orders of magnitude.
Better understanding the bonds between carbon group elements
Producing energy on Earth through nuclear fusion, the type of reaction that powers the sun, has proven to be a major challenge. The extreme conditions needed for such a reaction require the walls of a nuclear fusion device to be made of a material with a particular set of mechanical properties, including being able to withstand incredibly high temperatures and be shock- and corrosion-resistant....
Examining domain walls in magnetic nanowires
The bonds between clusters of elements in the fourteenth group of the periodic table are known to be fickle. Ranging from the nonmetal carbon, to the metalloids silicon and germanium, to the metals tin and lead, all these elements share the same configuration of valence electrons—electrons in their atoms' outermost energy level.
School closings during pandemic affected parents' work schedules, finds German study
Magnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, where the electrical resistance can vary based on the presence or absence of a domain wall.
The planning and design of environmental education sites from the perspective of pro-environmental behavior
A new study shows that the closing of education and childcare facilities in Germany during the coronavirus pandemic actually had an impact on parents' employment, as the opening of facilities led to a rebound in their work hours. For example, parents whose children had at least partial access to care or schooling in attendance worked about 1.5 to 2 hours more per week than parents whose children...
Buckle up: A new class of materials is here
Pro-environmental behavior (PEB) can help facilitate sustainable development, and PEB intervention strategies are developed to guarantee PEB effects. However, in most cases PEB intervention is given less importance than environmental education.
New grasshopper species from central Texas named in honor of two iconic musicians
Usually, the two characterizations of a material are mutually exclusive: something is either stiff, or it can absorb vibrations well—but rarely both. However, if we could make materials that are both stiff and good at absorbing vibrations, there would be a whole host of potential applications, from design at the nanoscale to aerospace engineering.
Examining the propagation of ultrasonic waves through liquids containing encapsulated bubbles
The central region of Texas is a known hotspot of biological wonders. For the last five years, Dr. JoVonn Hill, an Assistant Professor and Director of the Mississippi Entomological Museum (MEM) at Mississippi State University, and his colleagues have made scientific expeditions to the area that have now revealed an extraordinary find.
Speaking up for the annoying fruit fly
Scientists from the University of Tsukuba obtained a new theoretical equation for the propagation of ultrasonic waves through liquids containing encapsulated bubbles. They found that including the compressibility of the bubble shell was vital for accurately predicting the behavior of sound waves. This work may lead to improved resolution of ultrasound imaging based on the development of improved...
Banning multibuy discounts shown to drive sales rather than curb appetites
Fruit flies can be truly annoying when they are buzzing around your living room or landing in your wine. But we have much to thank these tiny nuisances for—they revolutionized biological and medical science.
Study shows more mutations likely with genetically engineered synthetic DNA
With the government under pressure to devise policies that help curb excessive consumption of unhealthy foods and drinks, new research from the University of East Anglia (UEA) finds that banning multibuy deals has the opposite effect.
Protecting dogs against outbreaks of respiratory disease
Unlocking the potential of laboratory-crafted DNA, known as synthetic DNA, holds the key to groundbreaking advancements across multiple domains, according to quantum biologists from the University of Surrey.
Dog owners are likely familiar with the respiratory disease commonly known as kennel cough; while most cases have been historically mild, a more severe form of the infection is on the rise.
