Physicists may have accidentally discovered a new state of matter

Posted by in categories: climatology, computing, mobile phones, physics

Humans have been studying electric charge for thousands of years, and the results have shaped modern civilization. Our daily lives depend on electric lighting, smartphones, cars, and computers, in ways that the first individuals to take note of a static shock or a bolt of lightning could never have imagined.

Now, physicists at Northeastern have discovered a new way to manipulate . And the changes to the future of our technology could be monumental.

“When such phenomena are discovered, imagination is the limit,” says Swastik Kar, an associate professor of physics. “It could change the way we can detect and communicate signals. It could change the way we can sense things and the storage of information, and possibilities that we may not have even thought of yet.”

Science Fact or Fiction: We Can Jump Between Parallel Universes

Posted by in categories: cosmology, futurism

Frequently used to change scenery in science fiction, parallel universes and the multiverse are indeed possible, but jumping from one to another might be a little tricky.

How resident microbes restructure body chemistry

Posted by in categories: biotech/medical, chemistry, genetics, neuroscience

The team compared germ-free (sterile) mice and mice with normal microbes. They used a laboratory technique called mass spectrometry to characterize the non-living molecules in every mouse organ. They identified as many molecules as possible by comparing them to reference structures in the GNPS database, a crowdsourced mass spectrometry repository developed by Dorrestein and collaborators. They also determined which living microbes co-locate with these molecules by sequencing a specific genetic region that acts as a barcode for bacterial types.

In total, they analyzed 768 samples from 96 sites of 29 different organs from four germ-free mice and four mice with normal microbes. The result was a map of all of the molecules found throughout the body of a normal mouse with microbes, and a map of molecules throughout a mouse without microbes.

A comparison of the maps revealed that as much as 70 percent of a mouse’s gut chemistry is determined by its gut microbiome. Even in distant organs, such as the uterus or the brain, approximately 20 percent of molecules were different in the mice with gut microbes.

A woman took 550 times the usual dose of LSD, with surprisingly positive consequences

Posted by in categories: biotech/medical, neuroscience

Drug overdoses can be life threatening, but for two women who accidentally took massive hits of LSD the experience was life changing — and in a good way.

A 46-year-old woman snorted a staggering 550 times the normal recreational dose of LSD and not only survived, but found that the foot pain she had suffered from since her 20s was dramatically reduced.

Separately, a 15-year-old girl with bipolar disorder overdosed on 10 times the normal dose of the drug, which she said resulted in a massive improvement in her mental health.

Goodbye Dental Implants, Dentist Grows New Teeth in Just 9 Weeks

Posted by in categories: biotech/medical, health

If you’ve ever had the misfortune of losing a tooth, you may have considered dental implants in the past. You may also have been surprised to learn how expensive they are, and that oftentimes materials such as mercury or silver are used.

But what if we could actually grow our teeth back? Fortunately, there is an incredible new development in oral health that could change the game entirely.

Dr. Jeremy Mao and his team from Columbia University were able to regrow teeth using stem cells as a ‘scaffold’ for the new tooth to grow over.

Time-Lapse Video of NASA’s James Webb Space Telescope Assembly, Sunshield Deployment

Posted by in category: space

In 2019, NASA’s James Webb Space Telescope celebrated the full mechanical and electronic assembly of the world’s largest, most powerful space science observatory ever built. Meaning that Webb’s two halves have been physically put together and its wiring harnesses and electronic interfaces have been fully connected.

Following assembly, the Webb team moved on to successfully send deployment and tensioning commands to all five layers of its sunshield, which is designed to unfold in space, and protect the observatory’s mirrors and scientific instruments from light and heat, primarily from the Sun.

“This has been an amazing journey to get here. The James Webb Space Telescope is now one complete assembly, and known to be the most powerful space telescope ever created by humankind,” said Mark Voyton, Webb Observatory Integration and Testing, and OTIS Manager at NASA’s Goddard Space Flight Center, Greenbelt, Maryland.
