Published A newly identified virus emerges from the deep
(via sciencedaily.com)
Original source 
Marine virologists analyzed sediment from the Mariana Trench, the deepest place on Earth, and identified a new bacteriophage.
Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery
(via sciencedaily.com) 
A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers
(via sciencedaily.com) 
Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully produce full-length spider silk proteins using silkworms. The findings demonstrate a technique that could be used to manufacture an environmentally friendly alternative to synthetic commercial fibers such as nylon.
Published Newfound brain circuit explains why infant cries prompt milk release
(via sciencedaily.com)
Original source 
Hearing the sound of a newborn's wail can trigger the release of oxytocin, a brain chemical that controls breast-milk release in mothers, a new study in rodents shows. Researchers found that once prompted, this flood of hormones continues for roughly five minutes before tapering off, enabling mothers to feed their young until they are sated or begin crying again.
Published New research brings greater understanding of Asian winter monsoon
(via sciencedaily.com)
Original source 
Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.
Published Novel organic light-emitting diode with ultralow turn-on voltage for blue emission
(via sciencedaily.com) 
An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional high voltage requirement for blue OLEDs, leading to potential advancements in commercial smartphone and large screen displays.
Published Black holes eat faster than previously expected
(via sciencedaily.com) 
While previous researchers have hypothesized that black holes eat slowly, new simulations indicate that black holes scarf food much faster than conventional understanding suggests. Some quasars brighten and disappear within months -- a time scale that aligns with the new findings.
Published Prehistoric fish fills 100 million year gap in evolution of the skull
(via sciencedaily.com)
Original source 
X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate.
Published Behavior is the secret to success for a range expansion
(via sciencedaily.com)
Original source 
While many species are undergoing drastic declines in their numbers and geographic ranges, other species seem to be thriving. Researchers investigating the great-tailed grackle, a bird that has been establishing new populations across North America in the past few decades, reveal that behavior might play a key role in their success. They found that the population on the range's edge is more persistent and has more variability in flexibility, and that this species has shifted toward living more in urban, arid environments.
Published Tall buildings could be built quicker if damping models were correct, study finds
(via sciencedaily.com) 
Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction
(via sciencedaily.com)
Original source 
A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
Published Imaging the smallest atoms provides insights into an enzyme's unusual biochemistry
(via sciencedaily.com) 
A team has used neutron crystallography to image all of the atoms in a radical intermediate of a copper amine oxidase enzyme. They disclosed previously unknown details, such as precise conformational changes, that help to explain the enzyme's biochemistry. This work might help researchers engineer enzymes that facilitate unusual chemistry or are highly efficient at room temperature that are useful in chemical industry.
Published Study shows life near the golf course isn't easy for alligators
(via sciencedaily.com)
Original source 
Living on a golf course dramatically changes alligator feeding habits.
Published Electrons take flight at the nanoscale
(via sciencedaily.com) 
A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed.
Published Fast-track strain engineering for speedy biomanufacturing
(via sciencedaily.com) 
Using engineered microbes as microscopic factories has given the world steady sources of life-saving drugs, revolutionized the food industry, and allowed us to make sustainable versions of valuable chemicals previously made from petroleum. But behind each biomanufactured product on the market today is the investment of years of work and many millions of dollars in research and development funding. Scientists want to help the burgeoning industry reach new heights by accelerating and streamlining the process of engineering microbes to produce important compounds with commercial-ready efficiency.
Published New recipes for origin of life may point way to distant, inhabited planets
(via sciencedaily.com)
Original source 
Life on a faraway planet -- if it's out there -- might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. Scientists have now exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions -- planetary versions of mixing techniques, oven temperatures and baking times -- for the recipes to come together.
Published Researchers discover a new species of larger benthic foraminifer from the Ryukyu Islands
(via sciencedaily.com)
Original source 
An international group of researchers have discovered a previously unknown species of large foraminifer, shedding new light on the ecological evolution and biodiversity of coral reefs in the Ryukyu Islands.
Published 16 strange new parasitoid wasp species discovered in Vietnam
(via sciencedaily.com)
Original source 
Researchers have discovered 16 new species of strange-looking parasitoid wasps from the Loboscelidia group. The study also revealed for the first time the unique parasitic behavior of a captive female from one species, who after parasitizing her host egg, buried the egg in a hole in the soil.
Published Machine learning models can produce reliable results even with limited training data
(via sciencedaily.com) 
Researchers have determined how to build reliable machine learning models that can understand complex equations in real-world situations while using far less training data than is normally expected.
Published Gene required for root hair growth, nitrate foraging found in grasses
(via sciencedaily.com)
Original source 
Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed 'BUZZ,' causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.
