The finding suggests that black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors.
Imagine a fleet of driverless taxis roaming your city, ready to pick you up and take you to your destination at a moment’s notice.

Researchers have discovered two strategies that enable Saharan silver ants to stay cool in one of the world’s hottest environments. They are the first to demonstrate that the ants use a coat of uniquely shaped hairs to control electromagnetic waves over an extremely broad range from the solar spectrum to the thermal radiation spectrum and that different physical mechanisms are used in different spectral bands to realize the same biological function of reducing body temperature.
Despite the intense activity and high hopes that surround the use of stem cells to reverse heart disease, scientists still face multiple roadblocks before the treatment will be ready for clinical prime time. Researchers are now finding ways to maximize the healing potential of stem cells by helping them overcome the inhospitable conditions of a damaged heart – bringing the promise of stem cell therapy for heart disease one step closer to reality.
Routine communications blackouts, between a re-entry spacecraft and ground control, can cause anxiety, as there is no way to know or control the location and state of the spacecraft from the ground, but researchers at the Harbin Institute of Technology in China have proposed a new way to maintain communication with spacecraft as they re-enter the atmosphere. The approach might also be applied to other hypersonic vehicles such as futuristic military planes and ballistic missiles.

Discovered in the 1970s, SERS is a sensing technique prized for its ability to identify chemical and biological molecules in a wide range of fields. It has been commercialized, but not widely, because the materials required to perform the sensing are consumed upon use, relatively expensive and complicated to fabricate. That may soon change. An international research team led by University at Buffalo engineers has developed nanotechnology that promises to make SERS simpler and more affordable. Described in a research paper published today in the journal Advanced Materials Interfaces, the photonics advancement aims to improve our ability to detect trace amounts of molecules in diseases, chemical warfare agents, fraudulent paintings, environmental contaminants and more.
