Two-dimensional (2D) materials - as thin as a single layer of atoms - have intrigued scientists with their flexibility, elasticity, and unique electronic properties, as first discovered in materials such as graphene in 2004. Some of these materials can be especially susceptible to changes in their material properties as they are stretched and pulled. Under applied strain, they have been predicted to undergo phase transitions as disparate as superconducting in one moment to nonconducting the next, or optically opaque in one moment to transparent in the next.
Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University's Brown School of Engineering. They're also tougher, more flexible and can essentially be painted onto devices.
The Rice lab of chemical and biomolecular engineer Matteo Pasquali tested antennas made of "shear-aligned" nanotube films. The researchers discovered that not only were the conductive films able to match the performance of commonly used copper films, they could also be made thinner to better handle higher frequencies.
Viruses, spread through mosquito bites, cause human illnesses such as dengue fever, Zika and yellow fever. A new control technique harnesses a naturally occurring bacterium called Wolbachia that blocks replication of viruses and breaks the cycle of mosquito-borne disease, according to an international team of researchers.
JUNE 10, 2019, NEW YORK - A Ludwig Cancer Research study has deciphered a complex molecular conversation between cancer and immune cells that is key to orchestrating the successful invasion of tumors by T cells that kill cancer cells.
Visible imagery from NASA's Terra satellite provided confirmation of the development of Tropical Cyclone 02A in the Arabian Sea, Northern Indian Ocean.
On June 10, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of 02A that showed thunderstorms circling the low-level center. MODIS imagery also showed some clouds and thunderstorms were offset to the northwest of the center. That's a result of outside winds or vertical wind shear, blowing from the southeast and pushing some clouds to the northwest.
How do you protect yourself from the perfect striking weapon? You develop the perfect shield.
RICHLAND, WASHINGTON, June 10, 2019 - A rapidly increasing percentage of the world's population is connected to the global information environment. At the same time, the information environment is enabling social interactions that are radically changing how and at what rate information spreads.
For many people, climate change feels like a distant threat -- something that happens far away, or far off in the future. Scientists and climate communicators often think that if everyone saw the devastating impacts of climate change, we'd all be more likely to accept it as real, and that accepting climate science is essential to taking action against it. A recent study, published in Regional Environmental Change, challenges the latter part of this assumption.
The search for dark matter is expanding. And going small.
While dark matter abounds in the universe - it is by far the most common form of matter, making up about 85 percent of the universe's total - it also hides in plain sight. We don't yet know what it's made of, though we can witness its gravitational pull on known matter.
Theorized weakly interacting massive particles, or WIMPs, have been among the cast of likely suspects comprising dark matter, but they haven't yet shown up where scientists had expected them.
Casting many small nets
(June 7, 2019) –- For more than a year, GozNym, a gang of five Russian cyber criminals, stole login credentials and emptied bank accounts from unaware Americans. To detect and quickly respond to escalating cyber-attacks like these, researchers at The University of Texas at San Antonio (UTSA) have developed the first framework to score the agility of cyber attackers and defenders. The cyber agility project was funded by the Army Research Office.
