COLUMBUS, Ohio -- Researchers have found a way to send tiny, soft robots into humans, potentially opening the door for less invasive surgeries and ways to deliver treatments for conditions ranging from colon polyps to stomach cancer to aortic artery blockages.
The researchers from The Ohio State University and the Georgia Institute of Technology detailed their discovery, which makes use of the ancient Japanese practice of origami, in a study published Sept. 14 in the Proceedings of the National Academy of Sciences.
Internet-of-Things (IoT) such as smart home locks and medical devices, depend largely on Bluetooth low energy (BLE) technology to function and connect across other devices with reduced energy consumption. As these devices get more prevalent with increasing levels of connectivity, the need for strengthened security in IoT has also become vital.
Philadelphia, September 21, 2020-- Using sensitive parameters to assess cardiac function, researchers at Children's Hospital of Philadelphia (CHOP) have found that cardiac involvement in multisystem inflammatory syndrome in children (MIS-C) differs from Kawasaki disease (KD) and is associated with myocardial injury. The findings were published recently in the Journal of the American College of Cardiology.
For the first time ever the majority of Germans are limiting their consumption of meat, and many are open to the concept of eating cultured meat, according to a new study.
Liquid metals (LMs) are promising for applications in flexible electronics and biomimetic functional composites. Nanometerization and surface modification of LMs are usually used to improve their substrate affinity and processing properties. In most cases, LM nanodroplets are encapsulated into ultrathin and fragile shells of oxides or amphiphile monolayers.
However, it may be hindered from being incorporated homogeneously into various composites through conventional processing methods. Therefore, producing stable and processable LM nanodroplets remains challenging.
A new study analyzing 16 years of data on tens of thousands of products finds that the adoption of nutrition data on "front of package" (FOP) labels is associated with improved nutritional content of those foods and their competitors.
The genomes of all higher life forms are stored in the cell nucleus on chromosomes. Chromosomes are composed of strands of the DNA molecule. The genetic information itself is encoded in a sequence of adjacent base pairs of the molecules adenine (A), cytosine (C), guanine (G) and thymine (T).
Lugano, Switzerland, 21 September 2020 - New data presented at ESMO 2020 have shown that immunotherapy is beneficial for patients with gastric and oesophageal cancers who currently have poor survival. (1-3)
Immune therapy would be a big change in treatment, since immune checkpoint inhibitors are not yet approved for early therapy in Western countries. Three studies provide evidence, based on different patient populations and different immune checkpoint inhibitors used as first-line therapy.

A new paper published today in Nature Energy reveals how a collaborative team of researchers have been able to fully identify the nature of oxidised oxygen in the important battery material - Li-rich NMC - using RIXS (Resonant Inelastic X-ray Scattering) at Diamond Light Source. This compound is being closely considered for implementation in next generation Li-ion batteries because it can deliver a higher energy density than the current state-of-the-art materials, which could translate to longer driving ranges for electric vehicles.
In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a "pi Earth" -- an Earth-sized planet that zips around its star every 3.14 days, in an orbit reminiscent of the universal mathematics constant.
New heat-harnessing "solar" cells that reflect 99% of the energy they can't convert to electricity could help bring down the price of storing renewable energy as heat, as well as harvesting waste heat from exhaust pipes and chimneys.
The energy storage application, known informally as a "sun in a box," stores extra wind and solar power generation in a heat bank.
URBANA, Ill. - Nearly a decade ago, the UN's Food and Agriculture Organization (FAO) developed a new index to assess protein quality in foods. The goal, writ large, was to address food security for the world's most vulnerable populations, creating more accurate tools for food assistance programs seeking to provide balanced nutrition.
Hans H. Stein at the University of Illinois knew he could help.
Pain is a protective mechanism, alerting us to danger by generating an unpleasant sensation. The warning message is carried to the spinal cord by specialized sensory neurons, which are intertwined with other sensory and motor neurons in peripheral nerves. If injury cannot be avoided, inflammation arises and is associated with redness, swelling and pain. "For a long time, pain and inflammation were thought to be distinct processes, generated independently.
Former Subtropical Storm Alpha was a short-lived storm that formed and fizzled within 24 hours. NASA-NOAA's Suomi NPP satellite found the remnants of former Subtropical storm Alpha spreading over Portugal and northwestern Spain.
Alpha formed off the coast of Portugal by 12:30 p.m. EDT (1630 UTC) on Friday, Sept. 18. Alpha made landfall in Portugal later that day around 5 p.m. EDT (2100 UTC) about 120 miles (195 km) north-northeast of Lisbon, Portugal.
While the power conversion efficiency of perovskite solar cells (PVSCs) - a future of solar cells - has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the stability issue without compromising efficiency, paving the way for real-life application of perovskite photovoltaic technology.
