Exploring why COVID-19 makes people lose their sense of smell

Doctors have reported that partial or total loss of the sense of smell is often an early symptom of infection with SARS-CoV-2, the virus that causes COVID-19. Now, researchers reporting in ACS Chemical Neuroscience have shown that in mice, two proteins required for SARS-CoV-2 entry are produced by cells of the nasal cavity that contribute to odor detection.

Improving image quality of CT scans

Computed tomography (CT) is one of the most effective medical tests for analysing the effects of many illnesses, including COVID-19, on the lungs. An international team led by the Universitat Oberta de Catalunya (UOC) has developed a new method that improves the quality of the images obtained from CT scans. The algorithm, which has been tested on simulated data, enables them to distinguish…

Understanding immunity to SARS-CoV-2

Why does every person react differently to an infection with the coronavirus SARS-CoV-2? Why do some people have no symptoms or only mild symptoms of COVID-19, the disease which it causes? And why do some people become so severely ill that they require ventilators or even die? These questions are being investigated by Professor Mascha Binder, director of the Department of Internal Medicine IV at…

3D imaging shows how diabetes twists nerve fibers

In an international collaboration led by Lund University in Sweden, researchers have used synchrotron light to study what happens to the nerves in diabetes. The technique shows the 3D-structure of nerve fibers in very high resolution. “This knowledge can be used to map mechanisms for how nerve fibers atrophy and grow back. It means that we can better understand how diabetes affects the nerves…

Using 'mini colons' to detect weaknesses of colorectal cancer

One of the main features of colorectal cancer is that there are considerable differences between the tumors of individual patients - at genetic level and hence in terms of the response to treatment too. Researchers from the German Cancer Consortium (DKTK) have developed a method that allows these differences to be identified more effectively.

AI speeds up search for COVID-19 treatments and vaccines

Researchers at Northwestern University are using artificial intelligence (AI) to speed up the search for COVID-19 treatments and vaccines. The AI-powered tool makes it possible to prioritize resources for the most promising studies — and ignore research that is unlikely to yield benefits. In the midst of the pandemic, scientific research is being conducted at an unprecedented rate. The Food and…

New AI tool for cardiac diagnostics

Artificial intelligence (AI) may be an aid to interpreting ECG results, helping healthcare staff to diagnose diseases that affect the heart. Researchers at Uppsala University and heart specialists in Brazil have developed an AI that automatically diagnoses atrial fibrillation and five other common ECG abnormalities just as well as a cardiologist. The study has been published in Nature…

Coronavirus clone produced in the lab

Researchers in virology and veterinary bacteriology at the University of Bern have cloned the novel coronavirus (SARS-CoV-2). The synthetic clones are being used by research groups worldwide to test corona samples, find antiviral drugs and develop vaccines as quickly as possible. The method developed in Bern can also be used in future to combat other highly infectious viruses. In the…

Improving immunotherapy for cancer

Our immune system not only protects us against infection, but also against cancer. This powerful protection is based in particular on the activation of special cells of the immune system, CD8+ T cells. These cells recognize infected or cancer cells and kill them specifically. “The ability of the immune system and especially CD8+ T cells to eliminate cancer cells in tissues such as the lung, gut…
