With the launch period for NASA's Mars Perseverance rover opening in a little less than four months, the six-wheeler is reaching significant pre-launch milestones almost daily at the Kennedy Space Center in Cape Canaveral, Florida. The rover had some components removed prior to being shipped from NASA's Jet Propulsion Laboratory in Southern California to the Cape in early February. Last week,...
Creating and controlling on Earth the fusion energy that powers the sun and stars is a key goal of scientists around the world. Production of this safe, clean and limitless energy could generate electricity for all humanity, and the possibility is growing closer to reality. Now a landmark report released this week by the American Physical Society Division of Plasma Physics Community Planning...
Chemists at Texas A&M University are taking a p[h]age from bacteria's playbook in order to beat viruses at their own game and develop new drugs to fight cancer and a host of other human diseases in the process.
North Carolina State University researchers have demonstrated that composite metal foams (CMFs) can pass so-called "simulated pool fire testing" with flying colors, moving the material closer to use in applications such as packaging and transportation of hazardous materials. In addition, researchers used this experimental data to develop a model for predicting how variations in the CMF would...
New Cornell University research is producing a more accurate historical timeline for the occupation of Native American sites in upstate New York, based on radiocarbon dating of organic materials and statistical modeling.
Using a single atom-thick sheet of graphene to track the electronic signals inherent in biological structures, a team led by Boston College researchers has developed a platform to selectively identify deadly strains of bacteria, an advance that could lead to more accurate targeting of infections with appropriate antibiotics, the team reported in the journal Biosensors and Bioelectronics.
A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army.
Using the unique capabilities of NASA's Hubble Space Telescope, a team of astronomers led by Virginia Tech's Nahum Arav has discovered the most energetic outflows ever witnessed in the universe.
Patrick Huber, a professor in the Virginia Tech Department of Physics, has co-authored an article that describes the potential uses and limitations of antineutrino detectors for nuclear security applications related to reactor, spent fuel, and explosion monitoring.
Researchers at Duke University and Michigan State University have engineered a novel type of supercapacitor that remains fully functional even when stretched to eight times its original size. It does not exhibit any wear and tear from being stretched repeatedly and loses only a few percentage points of energy performance after 10,000 cycles of charging and discharging.
U.S. school districts may be flagged as over-identifying students of color as having disabilities when other factors, such as achievement gaps, may explain these disparities, according to new Penn State research published in Exceptional Children.
Simon Fraser University researchers will use their pioneering imaging technology—called Mango, for its bright colour— to develop coronavirus testing kits. They're among a small set of Canadian researchers who responded to the rapid funding opportunity recently announced by the Canadian Institutes of Health Research (CIHR) to help address COVID-19.
Too often disasters come in threes. But the year of global pandemic and record wildfires in Australia will not also be a year of historic floods in the U.S., forecasters predict.
Tiny particles composed of metals and semiconductors could serve as light sources in components of future optical computers, as they are able to precisely localize and extremely amplify incident laser light. A team from Germany and Sweden led by Prof. Dr. Christoph Lienau and Dr. Jin-Hui Zhong from the University of Oldenburg has now explained for the first time how this process works. The study...
While beam steering systems have been used for many years for applications such as imaging, display, and optical trapping, they require bulky mechanical mirrors and are overly sensitive to vibrations. Compact optical phased arrays (OPAs), which change the angle of an optical beam by changing the beam's phase profile, are a promising new technology for many emerging applications. These include...
Someday, underwater robots may so closely mimic creatures like fish that they'll fool not only the real animals themselves but humans as well. That ability could yield information ranging from the health of fish stocks to the location of foreign watercraft.
Giraffes that are being translocated for conservation purposes should be moved in groups that contain at least 30 females and 3 males to ensure long-term population success. In two new studies, an international team of researchers identifies the ideal composition of a group to be moved and provides guidelines for all aspects of the translocation process, including decision-making and planning,...
G protein-coupled receptors (GPCRs) play essential roles in cell signal transduction and serve as important therapeutic targets for a large number of diseases. Upon binding to extracellular agonists, GPCRs stimulate various signaling pathways by recruiting different G proteins (Gs, Gi, Gq, etc.) to mediate a wide variety of physiological functions. The selective coupling between a GPCR and...
Stanford researchers have developed a technique that reprograms cells to use synthetic materials, provided by the scientists, to build artificial structures able to carry out functions inside the body.
A new study has provided the most comprehensive analysis of human genetic diversity to date, after the sequencing of 929 human genomes by scientists at the Wellcome Sanger Institute, the University of Cambridge and their collaborators. The study uncovers a large amount of previously undescribed genetic variation and provides new insights into our evolutionary past, highlighting the complexity of...
The tentative recovery of Africa's black rhino population was hailed by conservationists on Thursday as a cause for hopes that ambitious protection efforts could overcome the "acute threat" of poaching.
One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably the best-known proposal for a "theory of everything" that would tie together our understanding of the physical universe.
Researchers of the University of Groningen and the Max Planck Institute have found that starlings sleep five hours less per night during the summer. Compared to winter, the birds take more mid-day naps and live under higher sleep pressure. During full-moon nights, starlings sleep around two hours less than usual. The findings of the study were published in the journal Current Biology on 19 March.
Opening plastic packaging, such as plastic bags and bottles may contribute to the generation of small amounts of microplastics—small plastic particles less than 5 mm long—during daily tasks, according to a study published in Scientific Reports.
