Could Rotifers be the Next Great Laboratory Model?

Posted by in categories: bioengineering, biotech/medical

Rotifers are multicellular, microscopic marine animals that live in soils and freshwater environments. They are transparent and can be easily grown in large numbers. As such, they have been used in some laboratories as research subjects for many years. Now scientists have found a way to manipulate the rotifer genome, which can make them far more useful for many different research applications.

In new work reported in PLOS Biology, scientists used the CRISPR-Cas9 gene editing tool to alter two rotifer genes. These edits were then passed down to future generations of rotifers. This effort can now help others use these organisms in their laboratories.

Tiny particle’s ‘wobble’ could be start of a major discovery — scientists

Posted by in category: particle physics

The “wobble” of a tiny particle known as a muon is once again challenging our understanding of physics and could be the start of a major discovery, scientists have said.

For the third time, findings from experiments have shown this particle does not behave as predicted by the Standard Model – the rulebook physicists use to describe and understand how the universe works at the subatomic level.

Scientists said their latest results, which have been submitted to the journal Physical Review Letters, reinforce measurements of the muon’s wobble in previous experiments and are even more precise.

Hundreds of mysterious structures found at the heart of the Milky Way

Posted by in categories: physics, space

The above image may look like a piece of colourful, abstract art, but it is, in fact, a glimpse at the very heart of our galaxy.

Most of us can’t even begin to imagine what lurks beyond our solar system, but astrophysicists in the US have discovered a whole colony of incredible structures at the centre of the Milky Way.

Scientists already knew that mysterious, magnetised strands hang in space, but a new investigation has uncovered a whole new population of them, and found that they are handily pointing in the direction of the galactic centre.

MIT researchers turned concrete into an energy-storing supercapacitor with one cheap additive

Posted by in categories: energy, materials

What if you could turn concrete into a viable and effective energy storage option? While that might seem a bit out-of-this-world, that’s exactly what MIT researchers have managed to do, according to reports from New Atlas. A paper on the new concrete supercapacitor is also available in the Proceedings of the National Academy of Sciences (PNAS).

According to this research, MIT researchers were able to take an idea from 2021 – which said that you could store useful amounts of energy in concrete – and scale it up effectively by simply adding a single additive to the concrete mix. The mixture thus became a combination of concrete, water, and carbon black.

When combined, the three components allowed the researchers to create an energy-storing concrete supercapacitor that was easy to scale up, with it only requiring a change from “1-millimeter-thick electrodes to 1-meter-thick electrodes” to go from powering simple things like LED lights to full-blown buildings and homes.
