Published New study on mating behaviors offers clues into the evolution of attraction
(via sciencedaily.com) Original source In examining the mating rituals of roundworms, researchers uncovered a unique approach to reproduction that maximizes genetic fitness.
Published It's hearty, it's meaty, it's mold
(via sciencedaily.com) Original source Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
Published Advanced army robots more likely to be blamed for deaths
(via sciencedaily.com) Original source Advanced killer robots are more likely to blamed for civilian deaths than military machines, new research has revealed. The study shows that high-tech bots will be held more responsible for fatalities in identical incidents.
Published Alzheimer's drug fermented with help from AI and bacteria moves closer to reality
(via sciencedaily.com) Original source Researchers combined artificial intelligence and chemical biosensors to ferment the precursor of an Alzheimer's drug in bacteria.
Published New bioengineered protein design shows promise in fighting COVID-19
(via sciencedaily.com) Original source A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.
Published Even cells know the importance of recycling
(via sciencedaily.com) Original source Researchers uncovered the mechanistic details behind how several proteins interact to help cells recognize and remove damaged mitochondria. Optineurin (OPTN) and its interactions are needed to provide a contact site for another protein, Tank-binding kinase 1 (TBK1), during this process. The OPTN-TBK1 relationship is necessary for these mitochondria to be recognized and eliminated from the cell. This mechanism may have relevance for developing drugs to treat Parkinson's disease.
Published New simpler and cost-effective forensics test helps identify touch DNA
(via sciencedaily.com) Original source Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.
Published Robot ANYmal can do parkour and walk across rubble
(via sciencedaily.com) Original source The quadrupedal robot ANYmal went back to school and has learned a lot. Researchers used machine learning to teach it new skills: the robot can now climb over obstacles and successfully negotiate pitfalls.
Published Steroid drugs used for HRT can combat E. coli and MRSA
(via sciencedaily.com) Original source Researchers have combined computational and microbiology laboratory approaches to identify existing drugs that can be repurposed to combat antibiotic-resistant bacterial infections. This research has revealed that a class of steroid drugs currently used in hormone replacement therapy (HRT) can also stop the growth of antibiotic-resistant E. coli and effectively kill MRSA.
Published New computational strategy boosts the ability of drug designers to target proteins inside the membrane
(via sciencedaily.com) Original source Hitting targets embedded within the cell membrane has long been difficult for drug developers due to the membrane's challenging biochemical properties. Now, chemists have demonstrated new custom-designed proteins that can efficiently reach these 'intramembrane' targets.
Published Opening new doors in the VR world, literally
(via sciencedaily.com) Original source Recreating the action of opening doors in the virtual world requires engineering ways in which to provide the equivalent haptic feedback and steer users away from walls in the real world. A research group has done just this; developing RedirectedDoors+, which employs door robots and rotation to create a more realistic experience.
Published Straightening teeth? AI can help
(via sciencedaily.com) Original source A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.
Published You don't need glue to hold these materials together -- just electricity
(via sciencedaily.com) Original source Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electro-adhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies.
Published Simple trick could improve accuracy of plant genetics research
(via sciencedaily.com) Original source Researchers have published a simple trick that improves the accuracy of techniques that help us understand how external variables -- such as temperature -- affect gene activity in plants.
Published Milk to the rescue for diabetics? Cow produces human insulin in milk
(via sciencedaily.com) Original source An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
Published A simple and robust experimental process for protein engineering
(via sciencedaily.com) Original source A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study.
Published How a natural compound from sea squirts combats cancer
(via sciencedaily.com) Original source Trabectedin, a promising drug derived from the sea squirt Ecteinascidia turbinata, has shown potential in combating cancers resistant to conventional treatments. However, its precise mechanism of action has remained elusive -- until now.
Published Gene flow in giraffes and what it means for their conservation
(via sciencedaily.com) Original source Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.
Published Robotic interface masters a soft touch
(via sciencedaily.com) Original source Researchers have developed a haptic device capable of reproducing the softness of various materials, from a marshmallow to a beating heart, overcoming a deceptively complex challenge that has previously eluded roboticists.
Published Study illuminates the protective role of fluorescence in neon-colored sea anemones
(via sciencedaily.com) Original source A team of researchers has uncovered a direct genetic link between fluorescence and color in sea anemones -- those soft and tentacled tide pool creatures often encountered by beachgoers.
