According to the rules of thermodynamics, you need infinite time or energy to achieve absolute zero. But a new study says there is another way.

Light, sound, and heat are all types of energy around us. Thermodynamics is a branch of science that helps us understand how energy moves between objects. According to the third law of thermodynamics, it is impossible to cool any object to-273.15 degrees C (or absolute zero), which is the lowest temperature possible.

Now a research team from the Vienna University of Technology in Austria has found a way to cool an object to absolute zero. The study published in PRX Quantum demonstrates this alternate route using quantum computing.

The motion of an electron in a strong infrared laser field is tracked in real time by means of a novel method developed by MPIK physicists and applied to confirm quantum-dynamics theory by cooperating researchers at MPI-PKS. The experimental approach links the absorption spectrum of the ionizing extreme ultraviolet pulse to the free-electron motion driven by the subsequent near-infrared pulse. Their paper is published in the journal Physical Review Letters.

For this experimental scheme, the classical description of the electron motion is justified even though it is a quantum object. In the future, the new method demonstrated here for helium can be applied to more complex systems such as larger atoms or molecules for a broad range of intensities.

Black holes are considered to be voracious and sinister monsters in space. Until today they are not measurable by normal physical means — at least almost not! Only by two circumstances the giants betray themselves: They change the gravitational forces at their locations by their uncanny large mass — and they radiate! This only minimally, but enough to be able to prove the existence of the black holes. There is something very special about this radiation and today we will look at what it is and what researchers have had to go through in the laboratory to artificially create it. Before we get to that, we ask you to contribute to our channel. Write us your personal opinion in the comments at the end of the video or share your expertise with us.

If you’re a subscriber, you’ll even get a heart and we’ll pin your important contribution to the top. Just make sure you already have a subscription to The Simply Space, like the video and mention both at the beginning of your comment. Now we continue with the mysterious glow from the black hole and an experiment that could change everything.

I suspected both this and alzheimers are bacterial infections.

A common genus of microbe found in wet, boggy environments could play a key role in the development of Parkinson’s disease, by excreting compounds that trigger proteins inside brain cells to form toxic clumps.

The findings, made by a small team of researchers at the University of Helsinki and the University of Eastern Finland, build on the results of an earlier investigation showing that the severity of the neurodegenerative disorder in volunteers increased with concentrations of Desulfovibrio bacterial strains in their feces.

A team from Newcastle University and Northumbria University in the UK has found that the thin, root-like threads produced by many fungi can potentially be used as a biodegradable, wearable material that’s also able to repair itself.

In their tests, the researchers focused on the Ganoderma lucidum fungus, producing a skin from branching filaments known as hyphae, which together weave into a structure called a mycelium.

With a little more work the fragile skins could serve as a substitute for leather, satisfying vegan, environmental, and fashion tastes, though the process of its creation also needs to be sped and scaled up before it can be transformed into next season’s jacket.

On May 4, the first photovoltaic solar farm to connect directly to the UK’s National Grid transmission network went online.

Larks Green is a 200-acre solar farm located on the Severn Vale next to the hamlet of Itchington, to the north of Bristol, and with the addition of a big battery energy storage facility, it’s being heralded as a game-changer in creating a future where solar power is a consistent supplier of much of Britain’s electricity.

The 50 MW solar farm is owned and operated by Cero Generation and Enso Energy and was connected to the National Grid’s Iron Acton substation.

A startup called Chemix is using AI to move faster. Inside a San Francisco Bay Area lab, glowing machines—which look a little like servers in a data center—physically test different battery chemistries. Then the company’s software platform, called Mix, uses the data to help design new versions for testing, speeding up the cycle of iteration.

“It’s suggesting new molecules for us to test on a daily basis,” says cofounder and CEO Kaixiang Lin, who previously worked on battery design as a doctoral student at Harvard, a postdoc at Stanford, and at another battery startup. “We call it battery R&D on autopilot, because there’s very little human intervention in this process.”

It takes the system about six months, he says, to design new batteries that can beat the performance of existing batteries on the market by an average of 300%.

Glycans perform varied and crucial functions in numerous cellular activities. The diverse roles of glycans are matched by their highly complex structures, which derive from differences in composition, branching, regio-and stereochemistry, and modification. This incomparable structural diversity is challenging to the structural analysis of glycans.

Recently, a joint research group led by Prof. Qing Guangyan and Prof. Liang Xinmiao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has developed a glycan identification method based on nanopore single-molecule sensing through a glycan derivatization strategy. The study was published in Nature Communications on March 28.

Identifying and sequencing glycans using nanopore single-molecule techniques has sparked interest; however, it has achieved little progress over the past dozen years. Only a handful of cases that focused on either high molecular weight polysaccharides or some monosaccharides were reported.

Streacom and CALYOS are set to showcase the all-new fanless SG10 PC case at Computex 2023, which can passively cool and dissipate up to 600W.
