Machine-learning model helps determine protein structures

2021-02-04
CAMBRIDGE, MA -- Cryo-electron microscopy (cryo-EM) allows scientists to produce high-resolution, three-dimensional images of tiny molecules such as proteins. This technique works best for imaging proteins that exist in only one conformation, but MIT researchers have now developed a machine-learning algorithm that helps them identify multiple possible structures that a protein can take. Unlike AI techniques that aim to predict protein structure from sequence data alone, protein structure can also be experimentally determined using cryo-EM, which produces hundreds of thousands, or even millions, of two-dimensional images of protein samples frozen in a thin layer of ice. Computer algorithms then piece together these images, taken from different angles, into a three-dimensional ...

Spicy perfection isn't to prevent infection

2021-02-04
The next time you tuck in to a tikka masala you might find yourself asking a burning question: are spices used in dishes to help stop infection? It's a question many have chewed the fat over. And now thanks to new research from The Australian National University (ANU) we have an answer. The quick takeaway is: probably not. Professor Lindell Bromham and her colleagues asked why hot countries across the world tend to have spicy food? This pattern has led to what some have termed "Darwinian gastronomy" - a tummy-led cultural evolutionary process in countries with hotter climates. To find out the answer to their question, the researchers feasted on a true ...

'Where did I park my car?' Brain stimulation improves mental time travel

2021-02-04
You might remember you ate cereal for breakfast but forget the color of the bowl. Or recall watching your partner put the milk away but can't remember on which shelf. A new Northwestern Medicine study improved memory of complex, realistic events similar to these by applying transcranial magnetic stimulation (TMS) to the brain network responsible for memory. The authors then had participants watch videos of realistic activities to measure how memory works during everyday tasks. The findings prove it is possible to measure and manipulate realistic types of memory. "On a day-to-day basis we must remember complex events that involve many elements, such as different locations, people and objects," said lead author Melissa Hebscher, a postdoctoral fellow ...

New methods for exploring the 'dark matter' of biology

New methods for exploring the dark matter of biology
2021-02-04
New tools and methods have been described by WEHI researchers to study an unusual protein modification and gain fresh insights into its roles in human health and disease. The study - about how certain sugars modify proteins - was published today in Nature Chemical Biology. Led by WEHI researcher Associate Professor Ethan Goddard-Borger, this work lays a foundation for better understanding diseases like muscular dystrophy and cancer. At a glance WEHI researchers have developed new tools and methods to determine how 'tryptophan C-mannosylation', an unusual protein modification, impacts the stability and function ...

How metal atoms can arrange themselves on an insulator

How metal atoms can arrange themselves on an insulator
2021-02-04
In order to produce tiny electronic memories or sensors in future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now demonstrated that this is possible at room temperature: molecules of the metal-containing compound molybdenum acetate form an ordered structure on the insulator calcite without jumping to other positions or rotating. Their findings have been presented in the Nature Communications journal. The work was done in cooperation with researchers from the universities of Kaiserslautern, Lincoln (UK) and Mainz. 'Until now, it has been difficult ...

Probiotics or prebiotics? Exploring the complex world of 'gut' health

Probiotics or prebiotics? Exploring the complex world of gut health
2021-02-04
A healthy person has a general balance of good and bad bacteria. But that balance is thrown off when someone gets sick. So, to help boost their levels of good bacteria, many people take probiotic supplements -- live bacteria inside of a pill. Various commercial probiotic supplements are available for consumer purchase, and while health experts generally agree about their overall safety, controversy surrounds their efficacy. Inside the human body lives a large microscopic community called the microbiome, where trillions of bacteria engage in a constant "tug of war" to maintain optimal levels of good and bad bacteria. Most of this struggle takes place within the body's gastrointestinal tract, as bacteria help with digesting food and support the immune system. Although ...

City, University of London academic tracks COVID-19 dark web marketplaces

City, University of London academic tracks COVID-19 dark web marketplaces
2021-02-04
New research carried out by City data scientist, Dr Andrea Baronchelli, and colleagues, into the dark web marketplace (DWM) trade in products related to COVID-19, has revealed the need for the continuous monitoring of dark web marketplaces (DWMs), especially in light of the current shortage and availability of coronavirus vaccines. In their paper, Dark Web Marketplaces and COVID-19: before the vaccine published in the EPJ Data Science journal, Dr Baronchelli and his colleagues analysed 851,199 listings extracted from 30 DWMs between January 1, 2020 and November 16, 2020 before the advent of the availability of the coronavirus vaccine. They identify 788 listings directly related to COVID-19 products and monitor the temporal evolution of product categories including Personal Protective ...

Study shows flu vaccine lessens COVID-19 symptoms in children

2021-02-04
Researchers from the University of Missouri School of Medicine have discovered that children who receive a seasonal flu shot are less likely to suffer symptoms from a COVID-19 infection. The finding comes from a review of more than 900 children diagnosed with COVID-19 in 2020. "It is known that the growth of one virus can be inhibited by a previous viral infection," said Anjali Patwardhan, MD, professor of pediatric rheumatology and child health. "This phenomenon is called virus interference, and it can occur even when the first virus invader is an inactivated virus, such as the case with the flu vaccine." Patwardhan reviewed records from 905 pediatric patients diagnosed with COVID-19 between February and August 2020 to determine each patient's influenza vaccination history. ...
