Seeing is believing: Effectiveness of facemasks

No Result View All ResultNo Result View All ResultNo Result View All Result40403FAU College of Engineering and Computer Science researchers use flow visualization to qualitatively test facemasks and social distancingCredit: Florida Atlantic University, College of Engineering and Computer ScienceCurrently, there are no specific guidelines on the most effective materials and designs for facemasks to minimize the spread of droplets from coughs or sneezes to mitigate the transmission of COVID-19. While there have been prior studies on how medical-grade masks perform, data on cloth-based...

Existing drugs can prevent SARS-CoV-2 from hijacking cells | Scienmag: Latest Science and Health News

Researchers evaluate how the new coronavirus rewires human proteins for its own replication, and identify several antiviral drugs ready for clinical trialsCredit: Elizabeth Fischer, Miscroscopy Unit NIH/NIAIDAn international team of researchers has analysed how SARS-CoV-2, the virus that causes COVID-19, hijacks the proteins in its target cells. The research, published in the journal Cell, shows how the virus shifts the cell’s activity to promote its own replication and to infect nearby cells. The scientists also identified seven clinically approved drugs that could disrupt these...

Receptor makes mice strong and slim | Scienmag: Latest Science and Health News

Study by the University of Bonn identifies molecule that regulates two side effects of agingCredit: (c) Katharina Wislsperger/UKBonnIncreasing abdominal girth and shrinking muscles are two common side effects of aging. Researchers at the University of Bonn have discovered a receptor in mice that regulates both effects. Experiments with human cell cultures suggest that the corresponding signaling pathways might also exist in humans. The study, which also involved researchers from Spain, Finland, Belgium, Denmark and the USA, has now been published in the renowned journal Cell Metabolism.On...

Physicists obtain molecular 'fingerprints' using plasmons | Scienmag: Latest Science and Health News

Credit: Daria Sokol/MIPT Press OfficeScientists from the Center for Photonics and 2D Materials of the Moscow Institute of Physics and Technology (MIPT), the University of Oviedo, Donostia International Physics Center, and CIC nanoGUNE have proposed a new way to study the properties of individual organic molecules and nanolayers of molecules. The approach, described in Nanophotonics, relies on V-shaped graphene-metal film structures. Nondestructive analysis of molecules via infrared spectroscopy is vital in many situations in organic and inorganic chemistry: for controlling gas...

Atomic physics: Radiation pressure with recoil | Scienmag: Latest Science and Health News

Atomic physics: Radiation pressure with recoil | Scienmag: Latest Science and Health News

Frankfurt researchers deliver experimental proof for a 90 year-old theoryLight exerts a certain amount of pressure onto a body: sun sails could thus power space probes in the future. However, when light particles (photons) hit an individual molecule and knock out an electron, the molecule flies toward the light source. Atomic physicists at Goethe University have now observed this for the first time, confirming a 90 year-old theory.As early as the 16th century, the great scholar Johannes Kepler postulated that sunlight exerted a certain pressure, as the tail of the comets he observed...

One-time treatment generates new neurons, eliminates Parkinson's disease in mice | Scienmag: Latest Science and Health News

One-time treatment generates new neurons, eliminates Parkinson's disease in mice | Scienmag: Latest Science and Health News

Inhibiting a single gene converts many cell types directly into dopamine-producing neuronsCredit: UC San Diego Health SciencesXiang-Dong Fu, PhD, has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it. But a single discovery has launched Fu into a completely new field: neuroscience. For decades, Fu and his team at University of California San Diego School of Medicine studied a protein called PTB, which is well known for binding RNA and influencing which genes are turned “on” or...
