Appearance, social norms keep students off Zoom cameras

Cornell researchers surveyed the 312 students in the class at the end of the semester to figure out why they weren’t using their cameras – and to try to come up with ways to turn that trend around. They found that while some students had concerns about the lack of privacy or their home environment, 41% of the 276 respondents cited their appearance, and more than half of those who selected “other” as their reason for keeping their camera off explained that it was the norm. This suggested that explicitly encouraging camera use could boost participation without adverse effects, the researchers said.

Do simulations represent the real world at the atomic scale?

A multidisciplinary research team has developed a strategy to validate computer simulations of oxide/water interfaces at the atomic scale using X-ray reflectivity experiments. Such interfaces are key in many energy applications.

U.S. schools receive a C in whole child development in reimagined Nation’s Report Card

If the Nation’s Report Card, an annual report formerly known as the National Assessment of Educational Progress (NAEP), was reimagined to include physical and emotional health in addition to academics, the United States would receive a C average, says University at Buffalo educational policy expert Jaekyung Lee.

Fastener with Microscopic Mushroom Design Holds Promise

A Velcro-like fastener with a microscopic design that looks like tiny mushrooms could mean advances for everyday consumers and scientific fields. Currently available fasteners are called hook and loop fasteners and require harder, stiff material. In Biointerphases, researchers describe a design that can use softer materials and still be strong enough to work. The team believes a 3D mushroom design can be made with softer, more flexible materials and provide sufficient interlocking force on the fabric and hold strong.

Blockchain technology to optimize P2P energy trading

A Tokyo Tech research team led by Specially Appointed Professor Takuya Oda of the Institute of Innovative Research and Professor Keisuke Tanaka of the School of Computing, in collaboration with Mitsubishi Electric Corporation, has developed a new technology an original blockchain[1] technology that can optimize peer-to-peer (P2P) energy trading[2].

Light-induced twisting of Weyl nodes switches on giant electron current

Scientists at the U.S. Department of Energy’s Ames Laboratory and collaborators at Brookhaven National Laboratory and the University of Alabama at Birmingham have discovered a new light-induced switch that twists the crystal lattice of the material, switching on a giant electron current that appears to be nearly dissipationless. The discovery was made in a category of topological materials that holds great promise for spintronics, topological effect transistors, and quantum computing.

NAU-TGen study results show COVID-19 virus triggers antibodies from previous coronavirus infections

A collaborative study shows COVID-19 virus triggers antibodies from previous coronavirus infections, such as the common cold. It may also explain how previous exposure could partially account for differences in severity between old vs. young patients

Eggs Reveal What May Happen to Brain on Impact

Our brains consist of soft matter bathed in watery cerebrospinal fluid inside a hard skull, and in Physics of Fluids, researchers describe studying another system with the same features, an egg, to search for answers about concussions. Considering that in most concussive brain injuries, the skull does not break, they wanted to find out if it was possible to break or deform the egg yolk without breaking the eggshell and did a simple experiment using an egg scrambler, measuring the soft matter deformation.

DNA Origami Enables Fabricating Superconducting Nanowires

In AIP Advances, researchers describe how to exploit DNA origami as a platform to build superconducting nanoarchitectures. The structures they built are addressable with nanometric precision that can be used as a template for 3D architectures that are not possible today via conventional fabrication techniques. Inspired by previous works using the DNA molecule as a template for superconducting nanowires, the group took advantage of a recent bioengineering advance known as DNA origami to fold DNA into arbitrary shapes.

Moffitt Researchers Identify How Cancer Cells Adapt to Survive Harsh Tumor Microenvironments

To better understand the conditions that select for the Warburg Effect and the mechanisms where cells can express this metabolic adaptation, Moffitt researchers subjected nonmalignant cells to the harsh tumor microenvironment that is present during early carcinogenesis, known as ductal carcinoma in situ. In a new research article published in the Proceedings of the National Academy of Sciences, the Moffitt team shows that these conditions select for cells to express a Warburg Effect.

Gene-Editing ‘Scissor’ Tool May Also be a ‘Dimmer Switch’

In a series of experiments with laboratory-cultured bacteria, Johns Hopkins scientists have found evidence that there is a second role for the widely used gene-cutting system CRISPR-Cas9 — as a genetic dimmer switch for CRISPR-Cas9 genes. Its role of dialing down or dimming CRISPR-Cas9 activity may help scientists develop new ways to genetically engineer cells for research purposes.

New drug combination shows promise as powerful treatment for AML

Scientists have identified two drugs that are potent against acute myeloid leukemia (AML) when combined, but only weakly effective when used alone. The researchers were able to significantly enhance cancer cell death by jointly administering the drugs that are only partially effective when used as single-agent therapies.

Researchers use lasers and molecular tethers to create perfectly patterned platforms for tissue engineering

University of Washington researchers developed a technique to modify naturally occurring biological polymers with protein-based biochemical messages to affect cell behavior. Their approach uses near-infrared lasers to trigger chemical adhesion of proteins to scaffolds made from biological polymers like collagen.

Scientists Streamline Process for Controlling Spin Dynamics

UPTON, NY—Marking a major achievement in the field of spintronics, researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Yale University have demonstrated the ability to control spin dynamics in magnetic materials by altering their thickness. The study, published today in Nature Materials, could lead to smaller, more energy-efficient electronic devices.

UCI researchers: Climate change will alter the position of the Earth’s tropical rain belt

Irvine, Calif., Jan. 18, 2021 — Future climate change will cause a regionally uneven shifting of the tropical rain belt – a narrow band of heavy precipitation near the equator – according to researchers at the University of California, Irvine and other institutions. This development may threaten food security for billions of people.
