Your circadian rhythm doesn’t just govern your sleeping schedule; it can also impact cancer development, diagnosis, and treatment. In a review paper published in the journal Trends in Cell Biology, researchers discuss the role of circadian rhythms in tumor progression and spread and describe how we could better time when patients are tested for cancer and when they receive therapies to improve diagnostic accuracy and improve treatment success.

“The circadian rhythm governs most of the cellular functions implicated in cancer progression, and therefore its exploitation opens new promising directions in the fight against metastasis,” write the authors, molecular oncologists Zoi Diamantopoulou, Ana Gvozdenovic, and Nicola Aceto from the ETH Zurich in Switzerland.

Our circadian rhythms help our bodies synchronize different tasks throughout the day, including gene expression, immune function, and cell repair. We’ve long known that chronically disrupted circadian rhythms—as a result of erratic sleep patterns, jet lag, or shift work, for example—can predispose us to a number of health issues, including cancer. More recent work has shown that circadian rhythms are not only involved in tumor onset, but also govern cancer progression and metastasis, the colonization of secondary sites within the body.

Hinton, who works with Google and mentors AI’s rising stars, started looking at artificial intelligence over 40 years ago, when it seemed like something out of a science fiction story. Hinton moved to Toronto, Canada, where the government agreed to fund his research.

“I was kind of weird because I did this stuff everyone else thought was nonsense,” Hinton told CBS News.

Neurosity’s headset uses electroencephalogram technology, or EEG, to measure brain activity by placing small metal electrodes on a person’s scalp. If the electrodes detect decreased electrical activity in the brain, the Crown plays music and sounds, or pulses vibrations, hoping those actions will help the user focus.

But some developers, it seems, have taken Neurosity’s tech a step further, turning the Crown into a more traditional brain computer interface that can allow users to control a computer using only their mind.

One owner of the gadget claimed they’ve used it to drive a Tesla, moving the electric car short distances by doing some mental math, which signals to the device that the person wearing it is exerting a lot of cognitive effort.

The exceptional electronic properties of carbon nanotubes, coupled with their small size, makes them ideal materials for future nanoelectronic devices. The integration of these materials into advanced microprocessors requires a radical shift in fabrication from conventional top-down process to bottom-up assembly where advances in sorting and directed assembly are needed. This presentation will briefly describe the challenges to future transistor scaling, highlight the advantages of employing carbon nanotubes for digital logic and describe the recent progress in this area.

In a world first, a team of University of Wisconsin-Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art silicon transistors.

A big milestone for nanotechnology, this breakthrough could enable longer battery life, faster wireless communication and faster processing speeds for devices like smartphones and laptops.

Astronomers finally figure out what it’s like inside an actual, spinning black hole — and where exactly it’d kill you.

A planet the same size as Jupiter has been found around a surprisingly small red dwarf star about 285 light-years from our solar system. The gas giant is so large, relative to its host star, that it threatens to up-end long-held theories about how giant planets form.

It’s pretty well known that usually two sexes have to be involved for reproduction, but a team of scientists in Japan might have just blown that assumption out of the water. Led by Katsuhiko Hayashi, a professor of genome biology at Osaka University in Japan, the team have been able to create mice with parents who are both biologically male.
