Published Bioengineering breakthrough increases DNA detection sensitivity by 100 times



Researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
Published Study quantifies satellite brightness, challenges ground-based astronomy



The ability to have access to the Internet or use a mobile phone anywhere in the world is taken more and more for granted, but the brightness of Internet and telecommunications satellites that enable global communications networks could pose problems for ground-based astronomy. Scientists confirm that recently deployed satellites are as bright as stars seen by the unaided eye.
Published Bursts of star formation explain mysterious brightness at cosmic dawn



In the James Webb Space Telescope’s (JWST) first images of the universe’s earliest galaxies, the young galaxies appear too bright, too massive and too mature to have formed so soon after the Big Bang. Using new simulations, a team of astrophysicists now has discovered that these galaxies likely are not so massive after all. Although a galaxy’s brightness is typically determined by its mass, the new findings suggest that less massive galaxies can glow just as brightly from irregular, brilliant bursts of star formation.
Published Small but mighty new gene editor



A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published A deep look into the progression of Parkinson's Disease



Scientists have used cutting-edge imaging techniques to shed light on the progression of Parkinson's disease by studying how the main culprit, the protein alpha-synuclein, disrupts cellular metabolism.
Published An advance in cryo-EM could be a significant boon for research on potential cancer therapies



A technology called cryo-electron microscopy enables scientists to see the atomic structure of biological molecules in high resolution. But to date, it has been ineffective for imaging small molecules. A team of biochemists devised a solution that makes it possible to hold small protein molecules in place while they're being imaged, which will enable cryo-EM to produce much clearer images of such molecules. The advance is significant because small and medium-sized protein molecules are an area of focus in research on potential new drugs for cancer and other diseases.
Published Toxic formaldehyde's dual nature to be probed with new chemical tool



Newly developed ompounds aim to reveal the dual nature of formaldehyde, a chemical that is known to cause cancer but is also believed to play important roles in our biology.
Published Ethical guidelines needed before human research in commercial spaceflight is ready for liftoff



Before human research is conducted during commercial spaceflights, it should be 'ethically cleared to launch,' according to a global team of scientists, health policy experts and commercial spaceflight professionals.
Published Tiny CRISPR tool could help shred viruses



Scientists mapped out the three-dimensional structure of one of the smallest known CRISPR-Cas13 systems then used that knowledge to modify its structure and improve its accuracy.
Published Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova



A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers new insight into what happens in the final year prior to a star's death and explosion.
Published Strength is in this glass's DNA



Scientists were able to fabricate a pure form of glass and coat specialized pieces of DNA with it to create a material that was not only stronger than steel, but incredibly lightweight.
Published New proof for black hole spin



The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning.
Published Separating molecules requires lots of energy. This new, heat-resistant membrane could change that



A research team has created a new, heat-resistant membrane that can withstand harsh environments -- high temperatures, high pressure and complex chemical solvents -- associated with industrial separation processes. It could eventually be used as a less energy intensive alternative to distillation and other industrial processes that separate molecules that ultimately serve as ingredients in medicine, chemicals and other products.
Published How organic solar cells could become significantly more efficient



The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.
Published Study sheds new light on strange lava worlds


In a new study, scientists have shown that sweeping molten oceans have a large influence on the observed properties of hot rocky Super-Earths, such as their size and evolutionary path.
Published New insights into the atmosphere and star of an exoplanet


A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system's star and its planetary features.
Published Hidden supermassive black holes reveal their secrets through radio signals


Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies.
Published Copper-based catalysts efficiently turn carbon dioxide into methane


Copper-based catalysts developed by materials scientists help speed up the rate of carbon dioxide-to-methane conversion.
Published Drug discovery on an unprecedented scale


Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published Efficient fuel-molecule sieving using graphene


A research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.
