Researchers at the Paul Scherrer Institute PSI have improved a method for small angle X-ray scattering (SAXS) to such an extent that it can now be used in the development or quality control of novel fiber-reinforced composites. This means that in the future, such materials can be investigated not only with X-rays from especially powerful sources such as the Swiss Light Source SLS, but also with those from conventional X-ray tubes.

Astronomers have spotted an ultrafast star, traveling at a blistering 6 million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago. The discovery of the star, known as S5-HVS1, was made by Carnegie Mellon's Sergey Koposov as part of the Southern Stellar Stream Spectroscopic Survey (S5). Located in the constellation of Grus - the Crane - S5-HVS1 was found to be moving ten times faster than most stars in the Milky Way.

For the first time, researchers from Helmholtz Zentrum München and the University Hospital of LMU Munich show that deep learning algorithms perform similar to human experts when classifying blood samples from patients suffering from acute myeloid leukemia (AML). Their proof of concept study paves the way for an automated, standardized and on-hand sample analysis in the near future. The paper was published in Nature Machine Intelligence.

One million species are threatened with extinction, many of them already in the coming decades. This unprecedented loss of biodiversity threatens valuable ecosystems and human well-being. But what is holding us back from putting conservation research into practice? The journal Biological Conservation has published a collection of 14 articles on this topic. In their editorial, Bea Maas from the University of Vienna and her co-authors show why interdisciplinary cooperation is crucial for the conservation of global biodiversity.

A collaborative study published in Nature Medicine sounds a note of caution in using probiotics in the ICU. In a small percentage of cases, the live bacteria in the probiotic formulations can cause bloodstream infections. An investigation began when the Infection Prevention and Control group at Boston Children's Hospital began noticing cases of bacteremia in the ICU caused by Lactobacillus, a genus of bacteria commonly found in probiotics.

A study in iScience suggests a new approach that might help treat Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis: making people's cells better at killing Mtb by harnessing RNA sensors in our cells, which detect the RNA of invading pathogens. For the first time, researchers led by Anne Goldfeld, MD, of Boston Children's Hospital's Program in Cellular and Molecular Medicine, showed that RNA sensing is important in inhibiting Mtb's growth once it gets inside cells.

A new study in The American Journal of Pathology, published by Elsevier, reports that medroxyprogesterone acetate (MPA), the active ingredient in the common contraceptive injection Depo-Provera, was effective in preventing the development of cervical cancer in mice with precancerous lesions. The drug also decreased existing precancerous lesions. If proven effective clinically, MPA may be a boon to women who do not have access to human papillomavirus (HPV) vaccines.
