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 New study unveils scalable and efficient photoelectrode modules for green hydrogen production
(via sciencedaily.com) Original source A recent study has achieved a remarkable technological breakthrough in the production of green hydrogen.
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 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.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency
(via sciencedaily.com) Original source Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
Published Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
(via sciencedaily.com) Original source Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
Published 'Janitors' of the Sea: Overharvested sea cucumbers play crucial role in protecting coral
(via sciencedaily.com) Original source Researchers discovered that sea cucumbers -- sediment-eating organisms that function like autonomous vacuum cleaners of the ocean floor -- play an enormous role in protecting coral from disease.
Published Cutting-edge 'protein lawnmower' created
(via sciencedaily.com) Original source Scientists have designed the first synthetic protein-based motor which harnesses biological reactions to fuel and propel itself. 'Imagine if a Roomba could be powered only by the dirt it picks up,' says one of the authors of the study. The motor uses the digestive enzyme trypsin to cut the peptides and convert them into the energy it needs to propel itself.
Published What will it take for China to reach carbon neutrality by 2060?
(via sciencedaily.com) Original source To become carbon neutral by 2060, China will have to build eight to 10 times more wind and solar power installations than existed in 2022, according to a new study. Reaching carbon neutrality will also require major construction of transmission lines.
Published Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog
(via sciencedaily.com) Original source Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.
Published Robots, monitoring and healthy ecosystems could halve pesticide use without hurting productivity
(via sciencedaily.com) Original source Smarter crop farming that combats weeds, insect pests and plant diseases by integrating modern technologies like AI-based monitoring, robotics, and next-generation biotechnology with healthy and resilient agricultural ecosystems.
Published New world record for CIGS solar cells
(via sciencedaily.com) Original source A new record for electrical energy generation from CIGS solar cells has been reached. Scientists have achieved a 23.64 percent efficiency.
Published Blindness from some inherited eye diseases may be caused by gut bacteria
(via sciencedaily.com) Original source Sight loss in certain inherited eye diseases may be caused by gut bacteria, and is potentially treatable by antimicrobials, finds a new study in mice.
Published Global warming increases the diversity of active soil bacteria
(via sciencedaily.com) Original source Warmer soils harbor a greater diversity of active microbes, according to a new study. The study represents a significant shift in our understanding of how microbial activity in the soil influences the global carbon cycle and possible feedback mechanisms on the climate. Until now, scientists have assumed that higher soil temperatures accelerate the growth of microbes, thus increasing the release of carbon into the atmosphere. However, this increased release of carbon is actually caused by the activation of previously dormant bacteria.
Published Altering the circadian clock adapts barley to short growing seasons
(via sciencedaily.com) Original source To ensure that plants flower at the right time of year, they possess an internal clock, which enables them to measure the amount of daylight during a day. Biologists now describe that the mutation of a specific gene makes the flowering time of barley almost entirely independent of day length. This mutation can be useful for breeding varieties adapted to altered climatic conditions with relatively mild winters and hot, dry summers.
Published Lab-spun sponges form perfect scaffolds for growing skin cells to heal wounds
(via sciencedaily.com) Original source A new technique for electro-spinning sponges has allowed scientists to directly produce 3D scaffolds -- on which skin grafts could be grown from the patient's own skin.
Published 'Dynamic duo' defenses in bacteria ward off viral threats
(via sciencedaily.com) Original source Scientists have discovered that bacteria can pair up their defense systems to create a formidable force, greater than the sum of its parts, to fight off attack from phage viruses. Understanding how bacteria react to this type of virus is a big step in combating antimicrobial resistance.
