New materials for the computer of the future

Posted by in categories: computing, particle physics

Novel materials could revolutionize computer technology. Research conducted by scientists at the Paul Scherrer Institute PSI using the Swiss Light Source SLS has reached an important milestone along this path.

Microchips are made from silicon and work on the physical principle of a semiconductor. Nothing has changed here since the first transistor was invented in 1947 in the Bell Labs in America. Ever since, researchers have repeatedly foretold the end of the silicon era—but have always been wrong.

Silicon technology is very much alive, and continues to develop at a rapid pace. The IT giant IBM has just announced the first microprocessor whose transistor structures only measure two nanometers, equivalent to 20 adjacent atoms. So what’s next? Even tinier structures? Presumably so—for this decade, at least.

One-Minute Bursts of Activity During Daily Tasks Could Prolong Your Life

Posted by in category: biotech/medical

Summary: Three to four one-minute bouts of vigorous physical activity a day, such as running for a bus or walking fast to complete tasks reduces the risk of all-cause and cancer-related death by 40%, and a 49% reduced risk of death from cardiovascular disease.

Source: University of Sydney.

In good news for those who don’t like playing sport or going to the gym, new research finds just three to four one-minute bursts of huffing and puffing during daily tasks is associated with large reductions in the risk of premature death, particularly from cardiovascular disease.

A Ghostly Glow of Light Surrounds The Solar System, And Nobody Can Explain It

Posted by in category: space

A new analysis of Hubble data has clinched it: There’s too much light in the space around the Solar System.

Not much extra light, to be sure. Just a subtle, ghostly glow, a faint excess that can’t be accounted for in a census of all the light-emitting objects.

All the stars and galaxies surrounding the Solar System – and zodiacal light, aka dust on the Solar System’s plane – none of these can explain what astronomers are now calling “ghost light”.

Scientists Discover a Unique Gut Bacteria That May Cause Arthritis

Posted by in category: biotech/medical

Researchers at the University of Colorado School of Medicine have found that a unique bacteria found in the gut may be responsible for causing rheumatoid arthritis (RA) in patients who are already predisposed to the autoimmune disease.

A group of researchers from the Division of Rheumatology worked on the study under the leadership of Kristine Kuhn, MD, Ph.D., an associate professor of rheumatology. The study was recently published in the journal Science Translational Medicine. Meagan Chriswell, a medical student at CU, is the paper’s lead author.

“Work led by co-authors Drs. Kevin Deane, Kristen Demoruelle, and Mike Holers here at CU helped establish that we can identify people who are at risk for RA based on serologic markers, and that these markers can be present in the blood for many years before diagnosis,” Kuhn says. “When they looked at those antibodies, one is the normal class of antibody we normally see in circulation, but the other is an antibody that we usually associate with our mucosa, whether it be the oral mucosa, the gut mucosa, or the lung mucosa. We started to wonder, ‘Could there be something at a mucosal barrier site that could be driving RA?’”

James Webb Telescope’s Latest Discoveries

James Webb Telescope’s Latest Captures.

Welcome Back To Theory Of Science!
The James Webb Space Telescope is the largest, most powerful space telescope ever built. It will allow scientists to look at what our universe was like about 200 million years after the Big Bang. The telescope will be able to capture images of some of the first galaxies ever formed. It will also be able to observe objects in our solar system from Mars outward, look inside dust clouds to see where new stars and planets are forming and examine the atmospheres of planets orbiting other stars. The Webb telescope is as tall as a 3-story building and as long as a tennis court! It is so big that it has to fold origami-style to fit inside the rocket to launch. The telescope will unfold, sunshield first, once in space The James Webb Space Telescope sees the universe in light that is invisible to human eyes. This light is called infrared radiation, and we can feel it as heat. Firefighters use infrared cameras to see and rescue people through the smoke in a fire. The James Webb Space Telescope will use its infrared cameras to see through dust in our universe. Stars and planets form inside those dust clouds, so peeking inside could lead to exciting new discoveries! It will also be able to see objects (like the first galaxies) that are so far away that the expansion of the universe has made their light shift from visible to infrared! in this video, we are looking into James Webb Telescope’s Latest Captures.

Why the laws of physics don’t actually exist

Posted by in categories: mathematics, physics

What we call laws of physics are often just mathematical descriptions of some part of nature. Ultimate physical laws probably don’t exist and physics is all the better for it, says theoretical physicist Sankar Das Sarma.
