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.
In 2018, the physics world was set ablaze with the discovery that when an ultrathin layer of carbon, called graphene, is stacked and twisted to a "magic angle," that new double layered structure converts into a superconductor, allowing electricity to flow without resistance or energy waste. Now, in a literal twist, Harvard scientists have expanded on that superconducting system by adding a third layer and rotating it, opening the door for continued advancements in graphene-based superconductivity.
Scientists have found genetic differences between bats killed by white-nose syndrome and bats that survived, suggesting that survivors rapidly evolve to resist the fungal disease, according to a Rutgers-led study with big implications for deciding how to safeguard bat populations.
Niigata, Japan - Researchers from the Graduate School of Science and Technology at Niigata University, Japan along with their collaborators from Tokyo University of Science (Japan), Yamagata University (Japan) and University of Regensburg (Germany) have published a scientific article which enhances clarity on the understanding of proton conduction mechanism in protic ionic liquids.
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.
Osaka - Many different catalysts that promote the conversion of glucose to sorbitol have been studied; however, most offer certain properties while requiring compromises on others. Now, researchers from Osaka University have reported a hydrotalcite-supported nickel phosphide nanoparticle catalyst (nano-Ni2P/HT) that ticks all the boxes. Their findings are published in Green Chemistry.
PHILADELPHA--Inflammation in the blood could serve as a new biomarker to help identify patients with advanced pancreatic cancer who won't respond to the immune-stimulating drugs known as CD40 agonists, suggests a new study from researchers in the Abramson Cancer Center of the University of Pennsylvania published in JCI Insight
This study is the first randomised control trial to rigorously test a sequential approach to treating comorbid PTSD and major depressive disorder.
Findings from a trial of 52 patients undergoing three types of treatment regime - using only Cognitive Processing Therapy (CPT), using Behavioural Activation Therapy (BA) with some CPT, or CPT with some BA - found that a combined treatment protocol resulted in meaningful reductions in PTSD and depression severity, with improvements maintained at six-month follow-up investigations.
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.
Researchers from the international BASE collaboration at CERN, Switzerland, which is led by the RIKEN Fundamental Symmetries Laboratory, have discovered a new avenue to search for axions--a hypothetical particle that is one of the candidates of dark matter particles. The group, which usually performs ultra-high precision measurements of the fundamental properties of trapped antimatter, has for the first time used the ultra-sensitive superconducting single antiproton detection system of their advanced Penning trap experiment as a sensitive dark matter antenna.
Virtual 'exergaming' has become a popular way to exercise - especially among younger people - since the release of virtual reality (VR) fitness games on consoles such as Nintendo and Playstation.
But while VR is undoubtedly raising fitness games to a whole new level, researchers at the University of South Australia are cautioning players about the potential side effects of VR, particularly in the first hour after playing.
Today's digital world generates vast amounts of data every second. Hence, there is a need for memory chips that can store more data in less space, as well as the ability to read and write that data faster while using less energy.
A study published in the journal Pediatrics expands validation evidence for a new screening tool that directly engages preschool-age children during clinic visits to assess their early literacy skills. The tool, which is the first of its kind, has the potential to identify reading difficulties as early as possible, target interventions and empower families to help their child at home, according to researchers at Cincinnati Children's Hospital Medical Center.
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 necessary to develop additional COVID-19 vaccines, as different vaccine approaches have their advantages and disadvantages and may work synergistically. Researchers at Karolinska Institutet in Sweden now report that they have developed a prototype vaccine against SARS-CoV-2 using a DNA vaccine platform that is inexpensive, stable, easy to produce, and shows a good safety profile. A study published in Scientific Reports shows that the vaccine induces potent immune responses in mice.
