Published Molecular wires with a twist
(via sciencedaily.com) Original source Researchers have developed molecular wires with periodic twists. By controlling the lengths of regions between twists, the electrical conductivity of individual polymer chains can be enhanced. This work may lead to novel organic electronics or single-molecule wires.
Published Researchers teaching artificial intelligence about frustration in protein folding
(via sciencedaily.com) Original source Scientists have found a new way to predict how proteins change their shape when they function, which is important for understanding how they work in living systems. While recent artificial intelligence (AI) technology has made it possible to predict what proteins look like in their resting state, figuring out how they move is still challenging because there is not enough direct data from experiments on protein motions to train the neural networks.
Published New worm study paves way for better RNA-based drugs to treat human disease
(via sciencedaily.com) Original source Researchers have discovered RNA mechanisms that may lead to more effective, durable and targeted treatments for conditions like high cholesterol, liver diseases and cancers.
Published Explanation found for X-ray radiation from black holes
(via sciencedaily.com) Original source Researchers have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of the chaotic movements of magnetic fields and turbulent plasma gas.
Published Deadly sea snail toxin could be key to making better medicines
(via sciencedaily.com) Original source Scientists are finding clues for how to treat diabetes and hormone disorders in an unexpected place: a toxin from one of the most venomous animals on the planet.
Published Scientists discover new code governing gene activity
(via sciencedaily.com) Original source A newly discovered code within DNA -- coined 'spatial grammar' -- holds a key to understanding how gene activity is encoded in the human genome. This breakthrough finding revealed a long-postulated hidden spatial grammar embedded in DNA. The research could reshape scientists' understanding of gene regulation and how genetic variations may influence gene expression in development or disease.
Published Scientists harness quantum microprocessor chips for revolutionary molecular spectroscopy simulation
(via sciencedaily.com) Original source Engineering researchers have successfully developed a quantum microprocessor chip for molecular spectroscopy simulation of actual large-structured and complex molecules.
Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Peering into the mind of artificial intelligence to make better antibiotics
(via sciencedaily.com) Original source Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.
Published New insights on how bird flu crosses the species barrier
(via sciencedaily.com) Original source The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's polymerase when it interacts with a human protein essential for the virus to replicate within the cell. The structure of this replication complex provides important information about the mutations that avian influenza polymerase must undergo to adapt to mammals, including humans. These results can help scientists monitor the evolution and adaptability of bird flu strains, such as H5N1 or H7N9, towards infecting other species.
Published Searching old stem cells that stay young forever
(via sciencedaily.com) Original source The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
Published Preliminary study shows potential of Manuka honey as a nutraceutical for breast cancer
(via sciencedaily.com) Original source A new study found that Manuka honey could potentially be an alternative, natural option for breast cancer prevention and treatment -- particularly for estrogen receptor (ER)-positive breast cancer, the most common subtype of breast cancer that accounts for about 70-80% of all breast cancer cases.
Published Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
(via sciencedaily.com) Original source Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.
Published Knocking out one key gene leads to autistic traits
(via sciencedaily.com) Original source Hyperactivity, repetitive behavior, and language deficits all appeared in the mice, highlighting an unexpected role the cerebellum seems to play in autism.
Published Large Hadron Collider pipe brings search for elusive magnetic monopole closer than ever
(via sciencedaily.com) Original source New research using a decommissioned section of the beam pipe from the Large Hadron Collider (LHC) at CERN has bought scientists closer than ever before to test whether magnetic monopoles exist. Scientists have revealed the most stringent constraints yet on the existence of magnetic monopoles, pushing the boundaries of what is known about these elusive particles.
Published Researchers observe 'locked' electron pairs in a superconductor cuprate
(via sciencedaily.com) Original source The finding could help future efforts to design superconductors that work at higher temperatures.
Published New insight Into behavior of electrons
(via sciencedaily.com) Original source Physicists have uncovered new states of matter by exploring the behavior of flatland electrons in extreme conditions, revealing insights that could impact quantum computing and advanced materials.
Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Zebrafish use surprising strategy to regrow spinal cord
(via sciencedaily.com) Original source A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.
Published Surprise finding in study of environmental bacteria could advance search for better antibiotics
(via sciencedaily.com) Original source Researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's 'envelope' or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.
