Published Turning waste into gold
(via sciencedaily.com) Original source Researchers have recovered gold from electronic waste. Their highly sustainable new method is based on a protein fibril sponge, which the scientists derive from whey, a food industry byproduct.
Published When the music changes, so does the dance: Controlling cooperative electronic states in Kagome metals
(via sciencedaily.com) Original source Playing a different sound track is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective patterns emerge. For such a tiny stimulus to have an effect, the crowd needs to know more than just one dance. Electrons in metals tend to show only one behavior at zero temperature, when all kinetic energy is quenched.
Published A new plant's name that tells a story
(via sciencedaily.com) Original source A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.
Published A bright idea for recycling rare-earth phosphors from used fluorescent bulbs
(via sciencedaily.com) Original source Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.
Published Lockdowns had an impact on gut microbes and allergies in newborns, new research reveals
(via sciencedaily.com) Original source Lockdowns imposed during the COVID-19 pandemic had an impact on the gut microbiome development of babies born during these periods according to new research. Our gut microbiome, an ecosystem of microbes that live in our digestive tract, plays an essential role in human health. The study reveals significant differences in the microbiome development of babies born during lockdown periods when compared to pre-pandemic babies.
Published Study reveals accelerated soil priming under climate warming
(via sciencedaily.com) Original source A new study highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere.
Published New tool helps decipher gene behavior
(via sciencedaily.com) Original source Scientists have extensively researched the structure and sequence of genetic material and its interactions with proteins in the hope of understanding how our genetics and environment interact in diseases. This research has partly focused on 'epigenetic marks', which are chemical modifications to DNA, RNA, and the associated proteins (known as histones).
Published In fight against brain pathogens, the eyes have it
(via sciencedaily.com) Original source The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into the eyes of mice can help disable the herpes virus, a major cause of brain encephalitis. To their surprise, the vaccine activates an immune response through lymphatic vessels along the optic nerve.
Published How molecular 'handedness' emerged in early biology
(via sciencedaily.com) Original source Chemists fill a major gap in origin-of-life theories.
Published Avian influenza virus is adapting to spread to marine mammals
(via sciencedaily.com) Original source Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
Published Under pressure: New tool for precise measurement of superconductors
(via sciencedaily.com) Original source Researchers think they have a foundational tool for the thorny problem of how to measure and image the behavior of hydride superconductors at high pressure. They report creatively integrating quantum sensors into a diamond anvil cell, enabling direct readouts of the pressurized material's electrical and magnetic properties.
Published Radio waves can tune up bacteria to become life-saving medicines
(via sciencedaily.com) Original source Scientists have found a new way to alter the DNA of bacterial cells -- a process used to make many vital medicines including insulin -- much more efficiently than standard industry techniques.
Published Researchers develop novel method to photosynthesize hydrogen peroxide using water and air
(via sciencedaily.com) Original source Researchers have developed a microporous covalent organic framework with dense donor-acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide through the photosynthesis process with water and air.
Published Light stimulates a new twist for synthetic chemistry
(via sciencedaily.com) Original source Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more.
Published Double trouble at chromosome ends
(via sciencedaily.com) Original source New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
Published Change in gene code may explain how human ancestors lost tails
(via sciencedaily.com) Original source A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published Diamonds are a chip's best friend
(via sciencedaily.com) Original source New technologies aim to produce high-purity synthetic crystals that become excellent semiconductors when doped with impurities as electron donors or acceptors of other elements. Researchers have now determined the magnitude of the spin-orbit interaction in acceptor-bound excitons in a semiconductor. They broke through the energy resolution limit of conventional luminescence measurements by directly observing the fine structure of bound excitons in boron-doped blue diamond, using optical absorption.
Published New discovery shows how cells defend themselves during stressful situations
(via sciencedaily.com) Original source A recent study has unveiled an exciting discovery about how our cells defend themselves during stressful situations. The research shows that a tiny modification in the genetic material, called ac4C, acts as a crucial defender, helping cells create protective storage units known as stress granules. These stress granules safeguard important genetic instructions when the cell is facing challenges. The new findings could help shed light on relevant molecular pathways that could be targeted in disease.
Published Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins
(via sciencedaily.com) Original source Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.
