Stacking molecules like plates improves organic solar device performance      (via sciencedaily.com)     Original source 

Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.

Cracking the code of life: new AI model learns DNA's hidden language      (via sciencedaily.com)     Original source 

With GROVER, a new large language model trained on human DNA, researchers could now attempt to decode the complex information hidden in our genome. GROVER treats human DNA as a text, learning its rules and context to draw functional information about the DNA sequences.

Allergy cells' hidden secret      (via sciencedaily.com)     Original source 

Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils. This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions.

Coinfecting viruses impede each other's ability to enter cells      (via sciencedaily.com)     Original source 

The process by which phages -- viruses that infect and replicate within bacteria -- enter cells has been studied for over 50 years. In a new study, researchers have used cutting-edge techniques to look at this process at the level of a single cell.

Genetic signatures of domestication identified in pigs, chickens      (via sciencedaily.com)     Original source 

Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.

Stacked up against the rest      (via sciencedaily.com)     Original source 

Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.

Talking about regeneration      (via sciencedaily.com)     Original source 

Researchers transferred genes from simple organisms capable of regenerating their bodies into common fruit flies, more complex animals that cannot. They found the transferred gene suppressed an age-related intestinal issue in the flies. Their results suggest studying genes specific to animals with high regenerative capability may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.

More electricity from the sun      (via sciencedaily.com)     Original source 

A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.

Physicists use light to probe deeper into the 'invisible' energy states of molecules      (via sciencedaily.com)     Original source 

Physicists have experimentally demonstrates a novel physical effect that was predicted 45 years ago. The effect will result in a new chemical analysis technique, to simultaneously identify molecular bonds and their 3D arrangement in space. This new technique will find applications in pharmaceutical science, security, forensics, environmental science, art conservation, and medicine.

Green hydrogen: 'Artificial leaf' becomes better under pressure      (via sciencedaily.com)     Original source 

Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.

What no one has seen before -- simulation of gravitational waves from failing warp drive      (via sciencedaily.com)     Original source 

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.
