Thanks to a new design, the operation time for the plasma torch was extended.
A tiny clump of stars orbiting our galaxy should have been ripped apart by the Milky Way, but its continued existence hints it may be held together by a massive amount of dark matter.

April’s space watch list includes a Chinese space station mission and the test flight of a new Russian rocket.
Scientists have developed an ingestible capsule dotted with sensors that can detect pressure in a patient’s guts and detect points of failure.
The ingestible system will give colorectal medical teams an unprecedented understanding of the movement of a patient’s digestive tract, or lack thereof. Instead of simply taking images of inside the guts, the system will sense whether it’s contracting, how much pressure is exerted and exactly where it might be inactive.
The system has been tested in a synthetic gut and animals. A patent for the technology is pending.
A lot of people quickly learned about RNA when an RNA virus started the COVID-19 global pandemic. In humans, there are many forms of RNA, many of which are absolutely essential to life. Messenger RNA (mRNA) is generated from active genes, and used in cells to create proteins, control the expression of other genes, among an array of other functions. The various types of cells and tissues in the body are created and maintained through the expression of different genes, so the RNA that is present in a cell can tell us a lot about it.
Much of the genome is transcribed into RNA, even though not even two percent of the human genome encodes for proteins. There are small and long non-coding RNAs, which carry out regulatory or maintenance functions in the cell. Now that the human genome has been totally sequenced, researchers are turning their attention to the vast array of RNA molecules that are present in cells: the RNome, as well as their modifications. So far, 170 different types of RNA modifications have been identified, said Peter Dedon, MD, PhD, a Professor at MIT. RNA molecules can also interact with each other, DNA, or proteins.

After a rare captivity birth, a family of endangered siamang gibbons were “heard singing together” to celebrate the new arrival.
Using a blink-and-you’ll-miss-it experiment, researchers from Trinity College Dublin have discovered that individuals differ widely in the rate at which they perceive visual signals. Some people perceive a rapidly changing visual cue at frequencies that others cannot, which means some access more visual information per timeframe than others.
This discovery suggests some people have an innate advantage in certain settings where response time is crucial, such as in ball sports, or in competitive gaming.
The rate with which we perceive the world is known as our “temporal resolution,” and in many ways it is similar to the refresh rate of a computer monitor.
According to a new report, more and more companies are becoming concerned with advertisers integrating generative AI into their pipelines.
Fears about AI making decisions for you in the future are misplaced — because computers already control your life.
