An innovative, flexible solar cell being developed in South Korea has passed a crucial stress test.

Researchers from the Korea Advanced Institute of Science & Technology (KAIST) are working on a rubber-like sun-catcher made from organic materials. The idea is for these elastic cells to one day help power the wearable technology that is becoming more prevalent in society, per a KAIST research report.

“Through this research, we not only developed the world’s best performing stretchable organic solar cell, but it is also significant that we developed a new polymer that can be applicable as a base material for various electronic devices that needs to be malleable and/or elastic,” study lead Professor Bumjoon Kim said in the summary.

An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air — making it a valuable green fertilizer — and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study led by Penn State researchers suggests.

Native to the eastern U.S., the plant, azolla caroliniana Willd — commonly known as Carolina azolla — also could ease food insecurity in the near future, according to findings recently published in Food Science & Nutrition. The researchers found that the Carolina strain of azolla is more digestible and nutritious for humans than azolla varieties that grow in the wild and also are cultivated in Asia and Africa for livestock feed.

When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile, researchers have found a unique signature of this process for the first time — a scar imprinted on the surface of a white dwarf star. The results are published today in The Astrophysical Journal Letters.

“It is well known that some white dwarfs — slowly cooling embers of stars like our Sun — are cannibalising pieces of their planetary systems. Now we have discovered that the star’s magnetic field plays a key role in this process, resulting in a scar on the white dwarf’s surface,” says Stefano Bagnulo, an astronomer at Armagh Observatory and Planetarium in Northern Ireland, UK, and lead author of the study.

The scar the team observed is a concentration of metals imprinted on the surface of the white dwarf WD 0816–310, the Earth-sized remnant of a star similar to, but somewhat larger than, our Sun.

Gas stoves emit nanocluster aerosol that may get deep into your respiratory system, study shows. Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new Purdue University study has found.

Combustion remains a source of air pollution across the world, both indoors and outdoors. We found that cooking on your gas stove produces large amounts of small nanoparticles that get into your respiratory system and deposit efficiently, said Brandon Boor, an associate professor in Purdue’s Lyles School of Civil Engineering, who led this research.

Based on these findings, the researchers would encourage turning on a kitchen exhaust fan while cooking on a gas stove.

Imagine wearing a thin flexible sticker that can turn your hand or finger movement into communication without you having to say a word or tap a touch screen. Researchers have developed a new type of wearable sensor that can accomplish this futuristic feat and could open new possibilities for rehabilitation applications and help those with disabilities to communicate more easily.

The new sensor combines a soft and flexible material called polydimethylsiloxane, or PDMS, with an optical component known as a fiber Bragg grating (FBG). The researchers designed it to be comfortable for long-term wear while also having the ability to detect movements with high accuracy.

A paper describing this technology is published in the journal Biomedical Optics Express.

A recent study of thousands of galaxy clusters may ease a debate about the clumpiness of cosmic matter and reinforce the standard model of cosmology.

By mapping the largest structures in the universe in X-rays, cosmologists have found striking agreement with their standard theoretical model of how the universe evolves.

Having refined its charging algorithms, Polar Night Energy is now ready to scale up the storage tech in Pornainen.

Once completed, the new battery will be integrated with the network of Loviisan Lämpö, the Finnish heating company that supplies district heating in the area.

“Loviisan Lämpö is moving towards more environmentally friendly energy production. With the Sand Battery, we can significantly reduce energy produced by combustion and completely eliminate the use of oil,” says CEO Mikko Paajanen.

Leaving Earth for long periods requires highly specialised technical skills, but you also need to handle isolation, confined quarters and team conflict.
