Chemotherapy and organ transplantation not only take a huge toll on patients, but they can compromise the immune system and leave patients vulnerable to infections from microbes such as pathogenic fungi--the fastest-growing cause of hospital-acquired infections. Now researchers from Whitehead Institute for Biomedical Research have discovered one possible reason why these fungal microbes are such a scourge.
According to the research appearing in the August 7 online edition of the journal Nature Genetics, fungal microbes can quickly alter the appearance of their cell surfaces, their "skin," disguising themselves in order to slip past the immune systems vigilant defenses. And, for all the worlds brewers, the study also helps explain why certain beers are cloudy and others are clear.
"Its all about skin," says Whitehead Member Gerald Fink, who compares the fungal microbe to an M&M--a sugar coating encasing the cells DNA. "The skin of fungi microbes is what enables them to stick to your organs, and thus become pathogenic. It also enables the fungi to stick together, which is desirable for fermentation in beer."

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
