Circadian rhythm disruption tips the cell-cycle balance toward tumor growth

Disrupting normal circadian rhythms promotes tumor growth and suppresses the effects of a tumor-fighting drug, according to a new study publishing April 30 in the open-access journal PLOS Biology by Yool Lee, Amita Sehgal, and colleagues at the University of Pennsylvania. The results provide mechanistic support for "chronotherapy," the delivery of cancer drugs timed to the endogenous circadian rhythm.

Researchers develop secure method for sending sensitive personal data from wearable tech

Smart watches. Pacemakers. Internet-connected glasses. These are devices designed to make life easier. And yet, all this wearable technology can be hacked. The devices send personal health information to your smartphone over the airways, so anyone with the know-how could scoop it up and steal it. But now, researchers at Northeastern have a better, more secure idea: Send data through your body.

'Seeing the light' behind radiation therapy

Delivering just the right dose of radiation for cancer patients is a delicate balance in their treatment regime. However, in a new study from UBC Okanagan and Duke University, researchers have developed a system they say may improve the ability to maximize radiation doses to cancer tissues while minimizing exposure to healthy ones.

An ultra-stretchable triboelectric strip sensor (TSS) to control objects in 3-D space

Nanogenerators, technological tools that can convert mechanical or thermal energy into electricity, come in three key designs: piezoelectric, triboelectric and pyroelectric. While piezoelectric and triboelectric nanogenerators can convert mechanical energy into electricity, pyroelectric ones work by harvesting thermal energy.

What predicts college students' drinking habits? How much they think others are drinking.

Students' perception of how much their peers are drinking is one of the most important predictors of whether their alcohol use will increase in college—even more so than the actual drinking habits of their randomly assigned roommate, according to a new study by researchers at Virginia Commonwealth University.

New research takes deeper look at Venus's clouds

Venus is known for its clouds of sulfuric acid covering the entire planet and its super-fast winds moving at hundreds of kilometers per hour, but our neighboring planet's thick clouds make it difficult for scientists to peer deep inside its atmosphere.

Takes a licking and keeps on storing

Researchers at Washington University in St. Louis made an energy storage device that can withstand a hammer striking it more than 40 times. The shatterproof supercapacitor is also nonflammable, unlike lithium-ion batteries. The new work is the cover story of the April 23 issue of the journal Sustainable Energy and Fuels.

Computer scientists design way to close 'backdoors' in AI-based security systems

It sounds like a plot out of a spy novel, with a touch of cyberpunk: An agent approaches a secure location, protected by a facial recognition system, accessible only to a head of state or CEO. Flashing an unusually shaped earring, the agent tricks the system into thinking they're that VIP, opening the door and exposing the secrets inside. The key—an undetectable "sleeper cell" was placed inside the AI behind the security system months or years earlier to grant access to anyone wearing the specified jewelry.
