So cool and fascinating!!

If it were ever possible to take a flight through the extreme conditions of Neptune’s atmosphere, we might experience the fascinating phenomenon of diamond rain tapping at our window.

According to a new study by an international team of researchers, such a blizzard of bling could be relatively common throughout the Universe.

Carbon can link into a crystal on giant, icy gas planets like Neptune and Uranus because of the ultra-high temperatures and pressures deep down in the atmosphere. These conditions break up hydrocarbons like methane, allowing the carbon atoms within to connect with four others and make particles of solid diamond.

Quantum physicist Mickael Perrin uses graphene ribbons to build nanoscale power plants that turn waste heat from electrical equipment into electricity.

When Mickael Perrin started out on his scientific career 12 years ago, he had no way of knowing he was conducting research in an area that would be attracting wide public interest only a few years later: quantum electronics.

“At the time, physicists were just starting to talk about the potential of quantum technologies and quantum computers,” he recalls. “Today there are dozens of start-ups in this area, and governments and companies are investing billions in developing the technology further. We are now seeing the first applications in computer science, cryptography, communications, and sensors.”

Scientists have been aware of a specific organelle in plant cells for more than a hundred years. However, UC Riverside scientists have only now discovered the organelle’s key role in aging.

The researchers initially set out to understand more generally which parts of plant cells control plant responses to stress from things like infections, too much salt, or too little light. Serendipitously, they found this organelle, and a protein responsible for maintaining the organelle, control whether plants survive being left too often in the dark.

Because they had not expected this discovery, which is described in a Nature Plants journal article, the research team was thrilled.

From January 2019, Scott Pelley’s interview with “the oracle of AI,” Kai-Fu Lee. From this past April, Pelley’s report on Google’s AI efforts. And from this past March, Lesley Stahl’s story on chatbots like ChatGPT and a world of unknowns. #news #artificialintelligence #technology “60 Minutes” is the most successful television broadcast in history. Offering hard-hitting investigative reports, interviews, feature segments and profiles of people in the news, the broadcast began in 1968 and is still a hit, over 50 seasons later, regularly making Nielsen’s Top 10.

Electrons that spin to the right and the left at the same time. Particles that change their states together, even though they are separated by enormous distances. Intriguing phenomena like these are completely commonplace in the world of quantum physics. Researchers at the TUM Garching campus are using them to build quantum computers, high-sensitivity sensors and the internet of the future.

“We cool the chip down to only a few thousandths of a degree above absolute zero—colder than in outer space,” says Rudolf Gross, Professor of Technical Physics and Scientific Director of the Walther Meissner Institute (WMI) at the Garching research campus. He’s standing in front of a delicate-looking device with gold-colored disks connected by cables: The cooling system for a special chip that utilizes the bizarre laws of .

For about twenty years now, researchers at WMI have been working on quantum computers, a technology based on a scientific revolution that occurred 100 years ago when quantum physics introduced a new way of looking at physics. Today it serves as the foundation for a “new era of technology,” as Prof. Gross calls it.

The IVO quantum inertia drive is in orbit now and will be turned on within one to ten weeks and then operated for many weeks or months.

The IVO quantum inertia drive is very controversial because it would go against many theories in physics.

Let us assume the 52 millinewton drive using 1 watt of power from a drive that weighs about 200 grams works.

Untethered micro/nanorobots that can wirelessly control their motion and deformation state have gained enormous interest in remote sensing applications due to their unique motion characteristics in various media and diverse functionalities. Researchers are developing micro/nanorobots as innovative tools to improve sensing performance and miniaturize sensing systems, enabling in situ detection of substances that traditional sensing methods struggle to achieve. Over the past decade of development, significant research progress has been made in designing sensing strategies based on micro/nanorobots, employing various coordinated control and sensing approaches. This review summarizes the latest developments on micro/nanorobots for remote sensing applications by utilizing the self-generated signals of the robots, robot behavior, microrobotic manipulation, and robot-environment interactions.

Patients with takotsubo syndrome in a new study had elevated cardiovascular and noncardiovascular death rates. Inhibitors of the renin-angiotensin system were the only cardiovascular medications associated with reduced risk.

In takotsubo syndrome (TS) — also called stress cardiomyopathy or broken heart syndrome — long-term mortality is elevated, similar to that after acute myocardial infarction (AMI), but for unclear reasons. Additionally, evidence-based therapies are lacking for TS. To explore causes of death and the effects of heterogeneous therapies for TS, investigators in Scotland compared outcomes between 620 patients with TS, 620 matched patients presenting with AMI, and 2,480 matched individuals from the general population. Median follow-up was 5.5 years.

Among patients with TS, all-cause mortality was higher compared with the general population (hazard ratio, 1.8), both for cardiovascular causes (HR, 2.5) and noncardiovascular causes (HR, 1.5), but was lower compared with patients with AMI (HR, 0.8). Patients with TS were prescribed cardiovascular and noncardiovascular medications at similar rates to those with AMI. Use of diuretics, anti-inflammatory agents, and psychotropic agents were associated with higher mortality in patients with TS, as was chronic anti-inflammatory medication use. The only medications associated with lower mortality in patients with TS were inhibitors of the renin-angiotensin system.

This study adds to the body of evidence that shows that TS is a serious condition associated with higher mortality rates than the general population but slightly lower mortality rates than patients with AMI. These findings also support evidence suggesting that inhibitors of the renin-angiotensin system are associated with improved outcomes in TS. Although this study did not show an association between beta-blocker use and lower mortality in TS, many prior studies have found such a beneficial association. So, for now I will continue treating my patients with TS with both inhibitors of the renin-angiotensin system and beta blockers.
