Researchers discover new photoactivation mechanism for polymer production
A team of researchers has demonstrated a way to use low-energy, visible light to produce polymer gel objects from pure monomer solutions. The work not only poses a potential solution to current challenges in producing these materials, it also sheds further light on the ways in which low energy photons can combine to produce high energy excited states.
Researchers have developed the world's smallest ultrasound detector
Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as...
Reviewing the quantum material 'engine room', QAHE
An Australian collaboration reviews the quantum anomalous Hall effect (QAHE), one of the most fascinating and important recent discoveries in condensed-matter physics. QAHE allows zero-resistance electrical 'edge paths' in emerging quantum materials such as topological insulators, opening great potential for ultra-low energy electronics.
Scientists identify gene family key to unlocking vertebrate evolution
New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode in evolution where new genes played a significant role in the evolution of novel traits in vertebrates.
Scientists look into tropopause to find early signals of persistent strong rainfall
10 days before the peak rainfall, the joint action of the South Asia high and the Okhotsk Sea blocking high compresses the anomaly cold air between the two highs, and forms a narrow and steady cold air transport channel on the inclined isentropic surface.
Scientists studied color change from green to red in the fluorescent protein
Researchers undertook a detailed study on green-to-red photoconversion (light-induced conversion) of the Green Fluorescent Protein (GFP). In their recent study, scientists from Skoltech and their colleagues describe the molecular mechanism of photoconversion in detail for the first time ever.
Scientists updated genome editing technology
International scientific group compared their developed carriers for delivery of genome editing (GE) tools with other available analogues. The research of current studies were published in the in the journal Biomaterials.
Siberia's permafrost erosion has been worsening for years
The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena River by AWI experts show, the scale of erosion is alarming.
Skoltech research puts exciton-polaritons in their place with new artificial laser-built lattices
Researchers at the Hybrid Photonics Laboratories in Skoltech and Southampton (UK), in collaboration with Lancaster University (UK), have demonstrated a new optical method to synthesize artificial solid-state crystal structures for cavity-polaritons using only laser light. The results could lead to realization of field-programmable polariton circuitry and new strategies to create guided light and...
Slower growing chickens experience higher welfare, commercial scale study finds
Slower growing broiler chickens are healthier and have more fun than conventional breeds of birds, new evidence from an independent commercial scale farm trial has shown. The study carried out by researchers from FAI Farms, the University of Bristol and The Norwegian University of Life Sciences, is published today [16 September], in Scientific Reports.
Stanford team pinpoints brain circuitry underlying dissociative experiences
Stanford scientists identified key brain circuitry that plays a role in the mysterious experience called dissociation, in which people can feel disconnected from their own body and from reality.
Stop Livin to make lymphoma cells stop living
Researchers at the University of Tsukuba have shown that the protein Livin, an inhibitor of apoptosis or programmed cell death, mediates resistance to immunotherapy in some lymphoma variants. Therapeutically targeting Livin with IAP inhibitors or BET inhibitors may provide a practical strategy for patients with Livin-positive and other refractory B-cell lymphomas.
Sturdy fabric-based piezoelectric energy harvester takes us one step closer to wearable electronics
KAIST researchers presented a highly flexible but sturdy wearable piezoelectric harvester using the simple and easy fabrication process of hot pressing and tape casting. This energy harvester, which has record high interfacial adhesion strength, will take us one step closer to being able to manufacture embedded wearable electronics.
Sunfleck use research needs appropriate experimental leaves
The use of light by plant leaves to drive photosynthesis is often studied in steady state environments, but most plant leaves are required to adjust to fluctuations in incident light every day. The research into use of fluctuating light by plant leaves has expanded in recent decades.
SwRI scientist searches for stellar phosphorus to find potentially habitable exoplanets
SAN ANTONIO -- Sept. 16, 2020 -- A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find systems with the...
Systematic parental training helps the well-being of preschool children with ADHD
Research findings from Aarhus University and the Central Denmark Region's Child and Adolescent Psychiatric Centre show that quality of life is poorer for preschool children with ADHD compared to children from the control population. But the children's quality of life can be significantly improved using treatment without medication.
T cells take the lead in controlling SARS-CoV-2 and reducing COVID-19 disease severity
A multi-layered, virus-specific immune response is important for controlling SARS-CoV-2 during the acute phase of the infection and reducing COVID-19 disease severity, with the bulk of the evidence pointing to a much bigger role for T cells than antibodies. A weak or uncoordinated immune response, on the other hand, predicts a poor disease outcome.

Temple researchers discover new path to neuron regeneration after spinal cord injury
The astrocytic glial cell has the unique ability to form scar tissue around damaged neurons. The presence of scar tissue is associated with inhibitory effects on the regrowth of mature neurons that are damaged by spinal cord injury. Recent evidence suggests, however, that these inhibitory effects are reversible, and in new work, Temple and Penn scientists show that astrocytic glial cells can in...
