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.
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.
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.
Research by team from Nankai University shows new virus has mutated gene similar to those found in HIV and Ebola.
What if you went to the pharmacy and there was no medicine? What if you brought your kid to the hospital and they couldn’t treat them?
According to new research, an innovative stem cell technique ‘rapidly cured’ severe type 1 diabetes in mice. The benefits lasted for at least 9 months.
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.
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.
“Chang’e 4’s landing was no mean feat in itself. The reason why it is so difficult to send anything, robot or man, to the far side of the Moon, is because it is difficult to maintain communications with ground control on Earth with a giant rock in between (the Moon!).”
Chang’e-4 is the first spacecraft ever to land on the Moon’s far side.
