Lugano, Switzerland, 20 September 2020 - Post-operative radiotherapy (PORT) used in patients with non-small-cell lung cancer (NSCLC) following complete resection and after (neo) adjuvant chemotherapy shows no statistically significant difference in 3-year disease-free survival (DFS), according to data presented at ESMO 2020. These results give the oncology community a long-awaited answer. (1)
An inflammatory autoimmune response within the central nervous system similar to one linked to neurodegenerative diseases such as multiple sclerosis (MS) has also been found in the spinal fluid of healthy people, according to a new Yale-led study comparing immune system cells in the spinal fluid of MS patients and healthy subjects. The research, published Sept. 18 in the journal Science Immunology, suggests these immune cells may play a role other than protecting against microbial invaders -- protecting our mental health.
Scientists have used a new high-speed, in vitro selection method to isolate 9 antibody-like proteins (ALPs) that bind to the SARS-CoV-2 virus - 4 of which also exhibited neutralizing activity - within 4 days, according to a new study. While much research has focused on the identification of whole antibodies against SARS-CoV-2 - the causative agent of COVID-19 - less attention has been paid to ALPs, which include monobodies that can offer similar diagnostic and therapeutic advantages.
Six years after it began, the Flint, Michigan, water crisis remains among the highest-profile emergencies in the United States.
Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Hurricane Teddy's rainfall rates. Teddy is a major hurricane in the Central North Atlantic Ocean.
On Sept. 18, NOAA's National Hurricane Center (NHC) warned that Teddy remains a powerful hurricane over the Central Atlantic Ocean, and large ocean swells are forecast to spread across much of the western Atlantic increasing a rip current threat.

The list of hurricane names is officially used up with the development of the 23rd tropical cyclone of the year. Tropical Storm Wilfred just formed in the Eastern Atlantic Ocean today, Sept. 18. Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Wilfred's rainfall rates.
Subtropical Storm Alpha has formed near the coast of Portugal, becoming the first named storm using the Greek Alphabet list, now that the annual list of names is exhausted. NASA's Aqua satellite obtained visible imagery of the new storm.

Despite climate change being most obvious to people as unseasonably warm winter days or melting glaciers, as much as 95 percent of the extra heat trapped on Earth by greenhouse gases is held in the world's oceans. For that reason, monitoring the temperature of ocean waters has been a priority for climate scientists, and now Caltech researchers have discovered that seismic rumblings on the seafloor can provide them with another tool for doing that.

Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic resonance, magnetization patterns can be made visible. When using increasingly intense pulses, however, the magnetization image fades away. The mechanism responsible for this loss in resonant magnetic scattering intensity has now been clarified.
Every day, we make hundreds of decisions. While most are small and inconsequential, like choosing what to eat or wear, others are more complex and involve weighing up potential costs and benefits, like deciding whether to study more for a better grade instead of hanging out with friends.
As our lives become increasingly intertwined with technology -- whether supporting communication while working remotely or streaming our favorite show -- so too does our reliance on the data these devices create. Data centers supporting these technology ecosystems produce a significant carbon footprint -- and consume 200 terawatt hours of energy each year, greater than the annual energy consumption of Iran.
Solar storm analysis carried out by an army of citizen scientists has helped researchers devise a new and more accurate way of forecasting when Earth will be hit by harmful space weather.
Scientists at the University of Reading added analysis carried out by members of the public to computer models designed to predict when coronal mass ejections (CMEs) - huge solar eruptions that are harmful to satellites and astronauts - will arrive at Earth.
An immunotherapy drug called 'avelumab' has been shown to significantly improve survival in patients with the most common type of bladder cancer, according to results from a phase III clinical trial led by Queen Mary University of London and Barts Cancer Centre, UK.
This is the first time an immune therapy has resulted in a survival advantage in this setting in bladder cancer, and will potentially benefit thousands of patients each year.
Australian researchers and their colleagues from Russia and China have shown that it is possible to study the magnetic properties of ultrathin materials directly, via a new microscopy technique that opens the door to the discovery of more two-dimensional (2D) magnetic materials, with all sorts of potential applications.
