Published Synthetic biology meets fashion in engineered silk
(via sciencedaily.com)
Original source 
Engineers developed a method to create synthetic spider silk at high yields while retaining strength and toughness using mussel foot proteins.
Published Reinforcement learning: From board games to protein design
(via sciencedaily.com)
Original source 
An AI strategy proven adept at board games like Chess and Go, reinforcement learning, has now been adapted for a powerful protein design program. The results show that reinforcement learning can do more than master board games. When trained to solve long-standing puzzles in protein science, the software excelled at creating useful molecules. In one experiment, proteins made with the new approach were found to be more effective at generating useful antibodies in mice than were previous methods. If this method is applied to the right research problems, it likely could accelerate progress in a variety of scientific fields.
Published Fungal genetics could help develop novel biotechnologies
(via sciencedaily.com)
Original source 
An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
Published Engineering the next generation of cell and gene therapies
(via sciencedaily.com)
Original source 
Investigators are developing a novel way to treat amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa using engineered stem cells that may eventually lead to personalized treatments.
Published Simple addition to corn bran could boost grain's nutritional value 15-35%
(via sciencedaily.com)
Original source 
What if, by adding a couple of cell layers inside a corn kernel, the grain could become significantly richer in essential nutrients like iron, zinc, and protein? Such an improvement could benefit people who rely on corn for a large portion of their diet, as in many parts of the global south.
Published Study links 'stuck' stem cells to hair turning gray
(via sciencedaily.com)
Original source 
Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.
Published Loops, flags and tension in DNA
(via sciencedaily.com)
Original source 
Two protein complexes carry the major responsibility for the spatial organization of chromosomes in our cell nuclei. DNA tension plays a surprising role in this. Nanoscientists now publish how they have visualized this.
Published New mechanism for DNA folding
(via sciencedaily.com)
Original source 
A hitherto unknown mechanism for DNA folding is described in a new study. The findings provide new insights into chromosomal processes that are vital to both normal development and to prevent disease.
Published Novel nanocages for delivery of small interfering RNAs
(via sciencedaily.com)
Original source 
Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases. This has led to a growing demand for selective, efficient, and safe ways of delivering siRNA in cells. Now, in a cooperation between the Universities of Amsterdam and Leiden, researchers have developed dedicated molecular nanocages for siRNA delivery. In a paper just out in the Journal Chem they present nanocages that are easy to prepare and display tuneable siRNA delivery characteristics.
Published Fluorescent blue coumarins in a folk-medicine plant could help us see inside cells
(via sciencedaily.com)
Original source 
Plants that glow under ultraviolet (UV) light aren't only a figment of science fiction TV and movies. Roots of a traditional medicine plant called the orange climber, or Toddalia asiatica, can fluoresce an ethereal blue hue. And now, researchers have identified two coumarin molecules that could be responsible. These natural coumarins have unique fluorescent properties, and one of the compounds could someday be used for medical imaging.
Published A team creates 'quantum composites' for various electrical and optical innovations
(via sciencedaily.com)
Original source 
A team has shown in the laboratory the unique and practical function of newly created materials, which they called quantum composites, that may advance electrical, optical, and computer technologies.
Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com)
Original source 
A tiny biobattery that could still work after 100 years has been developed.
Published Next decade decisive for PV growth on the path to 2050
(via sciencedaily.com)
Original source 
Global experts on solar power strongly urge a commitment to the continued growth of photovoltaic (PV) manufacturing and deployment to power the planet, arguing that lowballing projections for PV growth while waiting for a consensus on other energy pathways or the emergence of technological last-minute miracles 'is no longer an option.'
Published SpyLigation uses light to switch on proteins
(via sciencedaily.com)
Original source 
Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to allow researchers to study and control them in more detail. This technology has potential uses in tissue engineering, regenerative medicine, and understanding how the body works. The scientists applied their new method to control the glow of a green fluorescent protein derived from Japanese eel muscle.
Published How electricity can heal wounds three times as fast
(via sciencedaily.com)
Original source 
Chronic wounds are a major health problem for diabetic patients and the elderly -- in extreme cases they can even lead to amputation. Using electric stimulation, researchers have developed a method that speeds up the healing process, making wounds heal three times faster.
Published New genetic target for male contraception identified
(via sciencedaily.com)
Original source 
Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com)
Original source 
Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published How a virus causes chromosomal breakage, leading to cancer
(via sciencedaily.com)
Original source 
Researchers describe how the Epstein-Barr virus exploits genomic weaknesses to cause cancer while reducing the body's ability to suppress it.
Published Study reveals how pollinators cope with plant toxins
