O.o!!!
An MIT researcher has gotten the 30-year-old computer game Doom running on actual gut bacteria. The frame rate is really bad, as the game would take nearly 600 years to beat.
Researchers have discovered how certain cells transform to help control blood pressure by producing renin, a substance usually made by specialized kidney cells. This breakthrough could lead to new treatments for high blood pressure and vascular diseases by targeting the genomic “switch” that regulates renin production. Researchers at…
The chapter summarizes the current information available from a variety of scientifically based guidelines and resources on dietary advice for those with diabetes. It is a practical overview for health care practitioners working in diabetes management. The chapter is divided into sections by content and includes sources for further reading. A primary message is that nutrition plans should meet the specific needs of the patient and take into consideration their ability to implement change. Often starting with small achievable changes is best, with larger changes discussed as rapport builds. Referral to medical nutrition therapy (MNT) provided by a Registered Dietitian Nutritionist (RDN) and a diabetes self-management education and support (DSMES) program is highlighted.

“We now need to continue observing this star to confirm the other candidate signals,” said Dr. Alejandro Suárez Mascareño. “But the discovery of this planet, along with other previous discoveries such as Proxima b and d, shows that our cosmic backyard is full of low-mass planets.”
How close are Earth-sized exoplanets to Earth? This is what a recent study published in Astronomy & Astrophysics hopes to address as a large international team of researchers have announced the discovery of Barnard b, which orbits Barnard’s star approximately 6 light-years from Earth. This discovery is profound because Barnard’s star is the closest single star to Earth but also because Barnard b is estimated to be approximately just over one-third the mass of the Earth, or approximately three times the mass of the planet Mars.
Barnard’s star is approximately 16 percent the mass of our Sun with approximately 19 percent of its diameter. While the size of Barnard b poses the possibility that it might be Earth-like, its 3.15-day orbit puts it well inside its star’s habitable zone (HZ).
“Barnard b is one of the lowest-mass exoplanets known and one of the few known with a mass less than that of Earth. But the planet is too close to the host star, closer than the habitable zone,” said Dr. Jonay González Hernández, who is a researcher at the Instituto de Astrofísica de Canarias in Spain, and lead author of the study. “Even if the star is about 2,500 degrees cooler than our Sun, it is too hot there to maintain liquid water on the surface.”
Yet despite the attraction of OAM monopoles for orbitronics, until this latest study, they have remained a theoretical dream.
Hedgehogs hide between theory and experiment.
To observe them experimentally, hope has lain with a technique known as Circular Dichroism in Angle-Resolved Photoemission Spectroscopy, or CD-ARPES, using circularly polarised X-rays from a synchrotron light source. Yet a gap between theory and experiment has in the past hindered researchers from interpreting the data. “Researchers may have had the data, but the evidence for OAM monopoles was buried in it,” says Schüler.

As President, Jimmy Carter established several science-related initiatives and policies.
Carter also sought to promote scientific research and development in a number of areas. He increased funding for basic science research in fields such as physics and chemistry, and established the National Commission on Excellence in Education to promote improvements in science and math education in American schools.
On top of that, Carter sought to address environmental issues through science policy. He established the Superfund program, which was created to clean up hazardous waste sites, and signed the Alaska National Interest Lands Conservation Act, which protected millions of acres of land in Alaska.
Researchers have recently observed a fascinating effect in the behavior of twisted light when it reflects off surfaces.
Everyday experience tells us that light reflected from a perfectly flat mirror will give us the correct image without any deformation. Interestingly, this is not the case when the light field itself is structured in a complex way. Tiny deformations appear.
Dr Shannon Curry said she believes humans will first land on Mars — at the earliest — in 2040, but more realistically 2050. And 2075 before Mars colonization! Very realistic prediction, and I enthusiastically agree.
NASA’s MAVEN spacecraft, led by scientists at the University of Colorado Boulder, was supposed to operate for one year when it entered orbit on September 21, 2014. Ten years later, the Mars Atmosphere and Volatile Evolution orbiter has been a boon to scientists studying the red planet and they hope it will remain in operation for years to come.
In May, MAVEN researchers got to watch as a huge solar storm hit the planet along with a massive dose of radiation. The MAVEN spacecraft is an orbiter, so it won’t ever land on the surface of Mars like the Curiosity and Perseverance rovers. Instead, it’s designed to examine the Martian atmosphere, which principal investigator Shannon Curry said “holds a number of secrets in terms of our past, present, and future.”
Here are some takeaways from Curry’s interview with Colorado Matters.
