A Physicist Has Worked Out The Math That Makes ‘Paradox-Free’ Time Travel Plausible

Posted by in categories: mathematics, physics, space, time travel

No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but in September last year a physics student Germain Tobar, from the University of Queensland in Australia, said he has worked out how to “square the numbers” to make time travel viable without the paradoxes.

Stomach Implant Tells Your Brain You’re Not Hungry

Posted by in categories: biotech/medical, food, neuroscience

A tiny implant offers a new weight loss option, and a gastric bypass alternative, for people suffering from obesity.

The device uses light to stimulate the nerve responsible for regulating food intake. A tiny glow from the implant and users don’t feel as hungry — instead, they feel full.

Researchers at Texas A&M say that this dime-sized device could provide a far less invasive surgical option than the so-called stomach stapling surgery — which is currently a last resort surgery for obese patients. This could be a viable option for a gastric bypass alternative.

Brain-to-brain communication demo receives DARPA funding

Posted by in categories: biotech/medical, neuroscience

HOUSTON — (Jan. 252021) — Wireless communication directly between brains is one step closer to reality thanks to $8 million in Department of Defense follow-up funding for Rice University neuroengineers.

The Defense Advanced Research Projects Agency (DARPA), which funded the team’s proof-of-principle research toward a wireless brain link in 2018, has asked for a preclinical demonstration of the technology that could set the stage for human tests as early as 2022.

Using CRISPR Genetic Technology to Catch Cancer in the Act

Posted by in categories: biotech/medical, computing, genetics

Using CRISPR technology, researchers are tracking the lineage of individual cancer cells as they proliferate and metastasize in real-time.

When cancer is confined to one spot in the body, doctors can often treat it with surgery or other therapies. Much of the mortality associated with cancer, however, is due to its tendency to metastasize, sending out seeds of itself that may take root throughout the body. The exact moment of metastasis is fleeting, lost in the millions of divisions that take place in a tumor. “These events are typically impossible to monitor in real time,” says Jonathan Weissman, MIT professor of biology and Whitehead Institute for Biomedical Research member.

Now, researchers led by Weissman, who is also an investigator with the Howard Hughes Medical Institute, have turned a CRISPR tool into a way to do just that. In a paper published on January 212021, in Science, Weissman’s lab, in collaboration with Nir Yosef, a computer scientist at the University of California at Berkeley, and Trever Bivona, a cancer biologist at the University of California at San Francisco, treats cancer cells the way evolutionary biologists might look at species, mapping out an intricately detailed family tree. By examining the branches, they can track the cell’s lineage to find when a single tumor cell went rogue, spreading its progeny to the rest of the body.
