In a lab on the first floor of the Thomas J. Watson, Sr., Laboratories of Applied Physics on Caltech’s campus, Bellan built a vacuum chamber with twin electrodes inside. To simulate the phenomenon, he charged a capacitor with enough energy to run the City of Pasadena for a few microseconds, then discharged it through the electrodes to create a miniature solar loop.

something-weird-logo-600.jpgScientists believe a lack of understanding of ocean life and its distribution is one of the biggest barriers to restoring marine biodiversity damaged by overfishing, pollution and
climate change.

Medieval philosophers debated how many angels could dance on the head of a pin; modern scientists are getting close to sticking a particle accelerator on one instead.

Ok, this particle accelerator doesn't fit on a one-cent piece, but it could manage on a larger one.

Excitons [pronounced exit-tawn].are a key part of many technologies, including solar panels, photodetectors and sensors, as well as light-emitting diodes found in televisions and digital display screens. In most cases, the exciton pairs are bound by electrical, or electrostatic, forces, also known as Coulomb interactions. Now, in a new study in Nature Physics, Caltech researchers report detecting excitons that are not bound via Coulomb forces but rather by magnetism.

space-based harvesters founded on the technology demonstrated by MAPLE could one day provide access to eight times as much solar energy on average as their terrestrial counterparts.
That harvested energy could then be dispatched to any place on Earth, including areas devastated by war or natural disaster, or regions with poor energy infrastructure, explains nanophotonic and solar-energy expert Harry Atwater, who is also one of SSPP’s principal investigators. “You could imagine in places like that, where you want to bring power to a large city, you could immediately do that without building a large power grid,” Atwater says. “The thing that’s really transformative about space solar power is that, unlike solar power on Earth, it has potential to eliminate the need for storage. You get power continuously, 24 hours a day, and you don’t have to come up with day-to-night storage, like in the form of batteries, or season-to-season storage.”

The new findings appear in a paper published in Nature Astronomy on September 28. Galaxies in our universe condense out of swirling clouds of gas. That gas then further condenses into stars that light up the galaxies, making them visible to telescopes in a range of wavelengths of light. Astronomers think that cold, dark filaments in deep space snake their way to the galaxies, supplying them with gas, which is fuel for making more stars.
Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web.
This detailed imaging of the web, will provide astronomers with missing information they need to understand the details of how galaxies form and evolve. It can also help astronomers map the distribution of dark matter in our universe (dark matter makes up about 85 percent of all matter in the universe, but scientists still don't know what it is made of ) .

In a study published in Nature Astronomy, astronomers from New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) have detailed radio observations of an extraordinary aurora-like display -- occurring 40,000 km above a relatively dark and cold patch on the Sun, known as a sunspot.
the magnetic activities of other stars, could have implications for astrophysicists to rethink their current models of stellar magnetic activity.

Mouse cleaning up the garage:
I saw this on the tele this morning. Brilliant to watch but what many people don't always realise is that mice continually dribble their urine as they move about. This urine can pass on some nasty germs, so I personally would take measures to get rid of the mouse.

These are thought to be like proton-wide wrinkles that emerged in the early Universe as space-time stretched, then froze into place. We've not found much physical evidence of cosmic strings, but the theoretical evidence is pretty promising.

Nuclear Fusion World Record Smashed in Major Achievement.
A team at the JET facility near Oxford in central England generated 69 megajoules for five seconds using 0.2 milligrams of fuel, beating its previous record set in 2022 by 10 megajoules, the UK Atomic Energy Authority (UKAEA) said.
That is enough to power around 41,000 homes for five seconds.
It is the final experiment to be conducted at the JET site using a donut-shaped machine called a tokamak.

I agree, rodents are a health hazard. Their urine can carry diseases like leptospirosis and hantavirus. I would also recommend implementing rodent control measures, or at least keeping them away from food and water sources.

Mind-blowing achievement in nuclear fusion! The potential for clean energy is truly remarkable. Exciting times ahead for science and technology!

Solid-state lithium-sulfur batteries are a type of rechargeable battery consisting of a solid electrolyte, an anode made of lithium metal and a cathode made of sulfur. These batteries hold promise as a superior alternative to current lithium-ion batteries as they offer increased energy density and lower costs. They have the potential to store up to twice as much energy per kilogram as conventional lithium-ion batteries -- in other words, they could double the range of electric vehicles without increasing the battery pack's weight.


By the way there are three more technologies in the pipeline that have not yet been published that I personally know of. Hint hint!

An object like this is impossible to create in the real world. As you move over the cubes which form the edge of this triangle, your visual perception is twisted to create the illusion of a three dimensional object that cannot exist in the real world
