Researchers 3D print tiny multicolor microstructures

Researchers have developed an automated 3D printing method that can produce multicolor 3D microstructures using different materials. The new method could be used to make a variety of optical components including optical sensors and light-driven actuators as well as multimaterial structures for applications such as soft robotics and medical applications.

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 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.

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.

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.

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...

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...
