Published DELLA proteins could hold key to the next Green Revolution
(via sciencedaily.com)
Original source 
A family of 'promiscuous' proteins found in all land plants is responsible for many different plant functions, despite remaining relatively unchanged for over 450 million years.
Published Cold is beneficial for healthy aging, at least in animals
(via sciencedaily.com)
Original source 
A lower body temperature is one of the most effective mechanisms to prolong the lifespan of animals. New research has now described precisely how this works. The scientists show that cold can prevent the pathological aggregation of proteins typical for two aging-associated neurodegenerative diseases.
Published Wastewater more potent breeding ground for antibiotic resistance than previously known
(via sciencedaily.com) 
Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.
Published Molecules precursors to life discovered in the Perseus Cloud
(via sciencedaily.com)
Original source 
A study has detected the presence of large quantities of complex organic molecules in one of the nearest star forming regions to the solar system.
Published Engineered E. coli delivers therapeutic nanobodies to the gut
(via sciencedaily.com)
Original source 
Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.
Published Microrobot technology: Externally connecting in vivo neural networks
(via sciencedaily.com) 
Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.
Published Scientists observe flattest explosion ever seen in space
(via sciencedaily.com)
Original source 
Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.
Published Form is (mal)function: Protein's shape lets bacteria disarm it
(via sciencedaily.com) 
Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
Published Boosting the body's anti-viral immune response may eliminate aging cells
(via sciencedaily.com)
Original source 
Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published Scientists see anti-aging potential in an invasive weed
(via sciencedaily.com)
Original source 
The fruit of the cocklebur plant, which grows worldwide and is often considered a noxious weed, has antioxidant and anti-inflammatory components that could make it useful as a skin protectant, according to new research.
Published Scientists discover hidden crab diversity among coral reefs
(via sciencedaily.com) 
The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.
Published Astronomers witness the birth of a very distant cluster of galaxies from the early Universe
(via sciencedaily.com)
Original source 
Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.
Published Detecting coral biodiversity in seawater samples
(via sciencedaily.com) 
Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.
Published Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions
(via sciencedaily.com) 
Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Published Marijuana-derived compounds could reverse opioid overdoses, researchers report
(via sciencedaily.com)
Original source 
Naloxone -- a fast-acting opioid antidote -- has saved lives, but it's less effective against powerful synthetic opioids, such as fentanyl. In an interesting twist, researchers are now investigating cannabidiol (CBD), a component of marijuana, as a possible alternative to the popular antidote. Today, a team reports compounds based on CBD that reduce fentanyl binding and boost the effects of naloxone.
Published Components of cytoskeleton strengthen effect of sex hormones
(via sciencedaily.com) 
Researchers discover that actin acts in the cell nucleus and is partly responsible for the expression of male sexual characteristics.
Published Redness of Neptunian asteroids sheds light on early Solar System
(via sciencedaily.com) 
Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red color, implying the existence of two populations of asteroids in the region, according to a new study by an international team of researchers.
Published Epigenetic fingerprint as proof of origin for chicken, shrimp and salmon
(via sciencedaily.com) 
Free-range organic chicken or factory farming? Scientists have developed a new detection method that can reveal such differences in husbandry. The so-called epigenetic method is based on the analysis of the characteristic patterns of chemical markers on the genome of the animals.
Published What should we call evolution driven by genetic engineering? Genetic welding, says researcher
(via sciencedaily.com) 
With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.
Published Team designs molecule to disrupt SARS-CoV-2 infection
(via sciencedaily.com) 
A team of scientists designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.
