A cleaner future for tires: Scientists pioneer chemical process to repurpose rubber waste
Every year, millions of tires end up in landfills, creating an environmental crisis with far-reaching consequences. In the United States alone, over 274 million tires were scrapped in 2021, with nearly a fifth of them being discarded into landfills. A study has now pioneered a technique for breaking down this rubber waste and transforming it into valuable precursors for epoxy resins. This technique offers an innovative and sustainable alternative to traditional recycling methods while significantly reducing rubber waste in landfills.

Blue pigment improves foundation makeup shades for dark skin
Drugstores and makeup counters carry foundations in various olive, ivory and fair shades. But for people with darker skin tones, finding the right foundation shade can be a challenge. The darker foundations that exist often fall flat, appearing gray-like once applied on the skin. But now, researchers report a blue cosmetic color additive that gives darker foundations the warmth and depth that current foundations lack.

A safe nuclear battery that could last a lifetime
Lithium-ion batteries, used in consumer devices and electric vehicles, typically last hours or days between charges. However, with repeated use, they degrade and need to be charged more frequently. Now, researchers are considering radiocarbon as a source for safe, small and affordable nuclear batteries that could last decades or longer without charging.

Making sturdy, semi-transparent wood with cheap, natural materials
Can you imagine having a smartphone with a wooden touchscreen? Or a house with wooden windows? Probably not -- unless you've heard of transparent wood. Made by modifying wood's natural structure, this material has been proposed as a sturdy, eco-friendly alternative for plastic. Researchers have created proof-of-concept transparent woods using almost entirely natural materials, and have explored making them electrically conductive, too.

Cleverly designed carbon nanohoop enables controlled release of iron
Researchers have developed a molecular system for controlled release of iron. They integrated ferrocene, a molecular sandwich that encloses an iron atom, with a carbon 'nanohoop'. As a result, the system allows for the release of Fe2+ ions upon activation with benign green light.

A multimodal light manipulator
Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas sensing and optical computing. Now, applied physicists have invented a new type of interferometer that allows precise control of light's frequency, intensity and mode in one compact package.

Engineering antibodies with a novel fusion protein
Even with significant expansion in the global market for antibodies used in clinical care and research, scientists recognize that there is still untapped potential for finding new antibodies. Many proteins group together in what are called protein complexes to carry out biological functions. The traditional method of generating antibodies by immunizing animals struggles to make antibodies related to these protein complexes. Scientists have now demonstrated that fusing protein complexes together adds stability during immunization and enables antibody generation.

Study documents impacts of large-scale entry of rooftop solar panels on competition
Fossil-fuel plants are increasingly being forced to stop and start production in response to changes in output from renewables. In a new study, researchers developed a dynamic competitive benchmark that accounts for start-up costs and other unit-level operating constraints. They apply their framework to Western Australia, a setting where rooftop solar capacity more than doubled between 2014 to 2018 to world-leading rooftop solar penetration rates. The study found that the large-scale expansion of rooftop solar capacity can lead to increases in the collective profitability of fossil fuel plants because competition softens at sunset--- plants displaced by solar during the day must incur start-up costs to compete in the evening.

BESSY II: Magnetic 'microflowers' enhance local magnetic fields
A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY II in collaboration with Dr Sergio Valencia. Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible.

Fluorescent caves could explain how life persists in extraterrestrial environments
Deep below the Earth's surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and the conditions for supporting life in extreme, and even extraterrestrial, environments.

Hydrophilic coating makes for unflappable golf balls
The condition of the grass on a golf course can drastically skew the chances of a winning putt regardless of a player's skill. Now, a coating that soaks up water molecules could slow the roll of a golf ball on a lightning-fast, dry course and speed it up on a sluggish, wet course without interfering with the ball when it's airborne.

E-scooter crashes mainly caused by reckless driving
Crashes on electric scooters are mostly due to the behavior of the riders, with one-handed steering and riding in a group being some of the largest risk factors. The researchers are also concerned about riders who deliberately crash or cause dangerous situations when riding, a phenomenon that seems to be specific to electric scooters.
