A new artificial-intelligence technology for heart imaging can improve care for patients, allowing doctors to examine their hearts for scar tissue while eliminating the need for contrast injections.

Investigators outline how a time-sensitive network control plane could be a key component of a workable quantum network. In addition to the well-understood requirements of transmission distance and data rate, for quantum networks to be useful in a real…

Researchers have developed three designs for compact speaker systems that control the direction of sound more efficiently than previous models. For each speaker, the scientists were able to manipulate the timing and strength of the outgoing sound waves…

Researchers have demonstrated that genes are capable of identifying and responding to coded information in light signals, as well as filtering out some signals entirely. The study shows how a single mechanism can trigger different behaviors from the sa…

Researchers detail how the protruding eyes and mouths on simulated stingrays affect a range of forces involved in propulsion, such as pressure and vorticity. They created a computer model of a self-propelled flexible plate that mimicked a stingray’s up…

Regenerative medicine researchers have created a model (using pluripotent stem cells) to show how dysfunction of a highly specialized cell of the air sacs, the type 2 pneumocyte, initiates the fibrotic cascade that characterizes a number of adult and p…

Researchers report how a protein molecular motor can chop off a piece of cell membrane. The constrict-and-cut mechanism resembles that of a ratchet motor, and is of importance in processes mediating the entry of particles into cells.

A new study found that on the days that leaders and managers were better able to reattach to work in the morning, they experienced higher positive moods and work focus and that in turn allowed them to be more successful throughout the day.

Results of a heat-confinement experiment on the twisty Wendelstein 7-X stellarator in Germany could enable devices based on the W7-X design to lead to a practical fusion reactor.

Does relationship quality continue to worsen, stabilize, or improve for distressed, help-seeking couples before they receive assistance? A team of researchers sought to answer that question in a new study examining what happens to couples who seek onli…

Telemedicine appointments combined with in-person visits significantly reduced the risk of further illness for children with medically complex cases.

The skyscrapers and urban development that have made Hong Kong the ‘Pearl’ have also generated pollutants that affect the marine species that live in Hong Kong’s coastal waters. On-going climate change and dams along the Pearl River have also altered t…

A single glass of wine can quickly — significantly — raise the drinker’s risk for atrial fibrillation, according to new research.

A buildup of coronavirus in the lungs is likely behind the steep mortality rates seen in the pandemic, a new study finds. The results contrast with previous suspicions that simultaneous infections, such as bacterial pneumonia or overreaction of the bod…
