Published How plants use sugar to produce roots
(via sciencedaily.com)
Original source 
Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to the research team leader.
Published Earliest evidence of wine consumption in the Americas found in Caribbean
(via sciencedaily.com)
Original source 
Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artefacts recovered from a small Caribbean island.
Published Limiting global warming to 1.5°C would save billions from dangerously hot climate
(via sciencedaily.com)
Original source 
Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests.
Published Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to 'the Great Dying'
(via sciencedaily.com)
Original source 
A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top predators.
Published Communities should reconsider walking away from curbside recycling, study shows
(via sciencedaily.com)
Original source 
Researchers took a deep dive into the economic and environmental value of community recycling efforts and compared it to the value of other climate change mitigation practices, concluding it provides a return on investment.
Published A giant leap forward in wireless ultrasound monitoring for subjects in motion
(via sciencedaily.com)
Original source 
Engineers have developed the first fully integrated wearable ultrasound system for deep-tissue monitoring, including for subjects on the go.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com)
Original source 
Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published Stretching metals at the atomic level allows researchers to create important materials for quantum, electronic, and spintronic applications
(via sciencedaily.com)
Original source 
A University of Minnesota Twin Cities-led team has developed a first-of-its-kind breakthrough method that makes it easier to create high-quality metal oxide films that are important for various next generation applications such as quantum computing and microelectronics.
Published New supply chain model to empower seabound hydrogen economy
(via sciencedaily.com)
Original source 
A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.
Published Nitrate: Healthy heart or cancer risk? Meet nutrition's Jekyll and Hyde
(via sciencedaily.com)
Original source 
For a long time nitrate has been viewed warily, with previous research showing it could potentially be linked to causing cancer. However, it has subsequently bee revealed to have various cardiovascular health benefits. So, which is it? A new review of dietary nitrate research shows the answers to its health benefits or risks may lie in where it is sourced from.
Published Demystifying vortex rings in nuclear fusion, supernovae
(via sciencedaily.com)
Original source 
Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source. A mathematical model linking these vortices with more pedestrian types, like smoke rings, could help engineers control their behavior in power generation and more.
Published Puppeteer fungus' targeted takeover of 'zombie' flies
(via sciencedaily.com)
Original source 
Researchers reveal the molecular and cellular underpinnings behind the parasitic fungus, Entomophthora muscae's (E. muscae), ability to manipulate the behavior of fruit flies.
Published Sensors that operate at high temperatures and in extreme environments
(via sciencedaily.com)
Original source 
Researchers have developed a new reliable and durable sensor that can work in temperatures as high as 900 degrees Celsius or 1,650 degrees Fahrenheit and can be used in multiple industries.
Published Artificial intelligence catalyzes gene activation research and uncovers rare DNA sequences
(via sciencedaily.com)
Original source 
Biologists have used machine learning, a type of AI, to identify 'synthetic extreme' DNA sequences with specifically designed functions in gene activation. They tested 50 million DNA sequences and found synthetic DNA sequences with activities that could be useful in biotechnology and medicine.
Published Physical chemists develop photochromic active colloids shedding light on the development of new smart active materials
(via sciencedaily.com)
Original source 
In nature, the skin of cephalopods (animals with tentacles attached to the head) exhibits unparalleled camouflage ability. Their skin contains pigment groups that can sense changes in environmental light conditions and adjust their appearance through the action of pigment cells. Although intricate in nature, this colour-changing ability is fundamentally based on a mechanical mechanism in which pigment particles are folded or unfolded under the control of radial muscles. Inspired by this natural process, a research team forms dynamic photochromic nanoclusters by mixing cyan, magenta and yellow microbeads, achieving photochromism on a macro scale.
Published An X-ray look at the heart of powerful quasars
(via sciencedaily.com)
Original source 
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment.
Published Synthetic biology: proteins set vesicles in motion
(via sciencedaily.com)
Original source 
Biophysicists have designed a new cell-like transport system that represents an important milestone on the road to artificial cells.
Published Even slight traffic noise has a negative impact on work performance
(via sciencedaily.com)
Original source 
As cities are densified at a fast pace, there is now construction very close to roads and thoroughfares. It is already known that noise can have a negative impact on human health, but new research shows that as little as 40 decibels of traffic noise -- the typical level of background noise in an office environment or kitchen -- has a detrimental effect on cognitive performance.
Published Ancient climate change solves mystery of vanished South African lakes
(via sciencedaily.com)
Original source 
New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.
