Matt Fitzgerald used to bike up and down 3,500 feet through the Santa Ana Mountains on three-hour rides just for fun. Now, nine months after being infected with SARS-CoV-2, the virus that causes Covid-19, he can’t muster walking on flat surfaces for 20 minutes without days of exhaustion. “My long Covid life remains terrifying,” [...]
Up to now, the use of models to research the barrier that separates the circulatory from the nervous system has proven to be either limited or extremely complicated. Researchers at ETH Zurich have developed a more realistic model that can also be used to better explore new treatments for brain tumours. Mario Modena is [...]
A Hamburg-based research team has developed a new method for producing a network of large to very fine pores in silicon and glass. At DESY’s X-ray source PETRA III, scientists led by DESY researchers Stella Gries and Patrick Huber were able to analyse the porosity using X-ray tomography. The method for producing micro- and [...]
Recently, researchers at Yale University and the University of Connecticut collaborated to develop a nanoparticle-based treatment to fight glioblastoma (GBM), one of the most harmful malignancies with a high recurrence rate and poor clinical outcome. This newly developed technique targets multiple factors associated with GBM progression and invasiveness. The findings were published in Science Advances. [...]
As devices get smaller and more powerful, the risk of them overheating and burning out increases substantially. Despite advancements in cooling solutions, the interface between an electronic chip and its cooling system has remained a barrier for thermal transport due to the materials’ intrinsic roughness. Sheng Shen, a professor of mechanical engineering Opens in [...]
A recent study conducted at Nagoya University has focussed on developing an all-in-one nanowire assay system that can capture and evaluate extracellular vesicles useful for early cancer diagnosis. Extracellular vesicles are promising biomarkers for the early detection of cancer. Different systems are available to capture and analyze extracellular vesicles, separately. This research was led by Associate [...]
Whether the light in our living spaces is on or off can be regulated in everyday life simply by reaching for the light switch. However, when the space for the light is shrunk to a few nanometers, quantum mechanical effects dominate, and it is unclear whether there is light in it or not. Both [...]
Cedars-Sinai Cancer investigators have developed a new nanotechnology-based test that can detect and profile prostate cancers—even in microscopic amounts. Their work, published in the journal Nano Today, suggests that this "liquid biopsy" test could spare many patients unnecessary treatment-related side effects, directing them instead to effective therapies that could prolong their lives. "This research will [...]
Accelerated climate change is a major and acute threat to life on Earth. Rising temperatures are caused by microbes producing 50% of atmospheric methane which is 30 times more potent than CO2 at trapping heat. These elevated temperatures are also accelerating microbial growth and thus producing more greenhouse gases than can be used by plants. [...]
The autoimmune disease multiple sclerosis can take a variety of courses. Determining the current and future progression of the disease is important in order to slow down its course as much as possible. Researchers at the University of Basel have presented a biomarker whose values in the blood allow such predictions. The researchers focused [...]
