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 High resolution imagery advances the ability to monitor decadal changes in emperor penguin populations
(via sciencedaily.com) Original source Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.
Published Sonic youth: Healthy reef sounds increase coral settlement
(via sciencedaily.com) Original source Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages coral larvae to settle there. This indicates that it's possible that 'acoustic enrichment' can be a key intervention to support imperiled reefs.
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 Scientists find weak points on Epstein-Barr virus
(via sciencedaily.com) Original source Studies of interactions between two lab-generated monoclonal antibodies (mAbs) and an essential Epstein-Barr virus (EBV) protein have uncovered targets that could be exploited in designing treatments and vaccines for this extremely common virus.
Published History repeats as Coral Bay faces mass loss of coral and fish life
(via sciencedaily.com) Original source A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.
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 A coral superhighway in the Indian Ocean
(via sciencedaily.com) Original source Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'
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 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.
Published New study reveals transgenerational effects of pesticide linuron on frogs
(via sciencedaily.com) Original source Grand-offspring of male frogs exposed to the pesticide linuron exhibited changes in their DNA that was linked to significant physiological impacts, a study reveals. The research highlights the profound transgenerational consequences of environmental pollution on amphibian populations, which are already under threat of extinction.
Published Researchers uncover protein responsible for cold sensation
(via sciencedaily.com) Original source Researchers have identified the protein that enables mammals to sense cold, filling a long-standing knowledge gap in the field of sensory biology.
Published Muscaris grapes: Molecular secret of lychee note revealed
(via sciencedaily.com) Original source Researchers have succeeded in identifying the odorants responsible for the characteristic lychee note of Muscaris grapes.
Published Anemonefish are better taxonomists than humans
(via sciencedaily.com) Original source Scientists reveal new lineages of giant sea anemones in Japan and their surprising associations with anemonefish.
Published 'Molecular Rosetta Stone' reveals how our microbiome talks to us
(via sciencedaily.com) Original source Researchers have uncovered thousands of previously unknown bile acids, a type of molecule used by our gut microbiome to communicate with the rest of the body.
Published Halloween toy among plastics swallowed by sea turtles
(via sciencedaily.com) Original source A Halloween toy was among hundreds of plastic items found in the guts of dead sea turtles in the Mediterranean, a new study reveals.
Published Research sheds light on new strategy to treat infertility
(via sciencedaily.com) Original source New research describes the science behind a promising technique to treat infertility by turning a skin cell into an egg that is capable of producing viable embryos. The technique could be used by women of advanced maternal age or for those who are unable to produce viable eggs due to previous treatment for cancer or other causes. It also raises the possibility of men in same-sex relationships having children who are genetically related to both parents.
Published New study discovers how altered protein folding drives multicellular evolution
(via sciencedaily.com) Original source Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution.
