New method accurately detects virulent infections in advance

When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy.

New computational technique greatly increases the resolution of atomic force microscopy

Scientists at Weill Cornell Medicine have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that "feels" the atoms at a surface.

New transparent material can capture respiratory droplets effectively from air

Although plexiglass barriers are seemingly everywhere these days -- between grocery store lanes, around restaurant tables and towering above office cubicles -- they are an imperfect solution to blocking virus transmission.

Scientists capture real-time electrical activity of a beating heart using graphene 'camera'

Bay Area scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image -- almost like a video camera -- of the faint electric fields generated by the rhythmic firing of the heart's muscle cells.

Study reveals structural details of omega-3 fatty acid transport across the blood–brain barrier

Spectacular images of a molecule that shuttles omega-3 fatty acids into the brain may open a doorway for delivering neurological therapeutics to the brain.

Differential localization may explain different physiological functions of receptors

In the heart there are two different subtypes of beta-adrenergic receptors - beta1 and beta2 - which are activated by the stress hormones adrenaline and noradrenaline.

Novel calibration process for super-resolution microscopy

Light--and all waves--can bend around the corners of obstacles found along its path. Because of this phenomenon, called diffraction, it is impossible to focus light onto a spot that is smaller than half its wavelength.

New digital tool makes the analysis of microscopy images much easier

Information technology can make life easier in many areas - including research. In medicine, for example, it is still standard practice to evaluate microscopy images of tissue sections by hand. This is used, for example, to assess how many cancer cells are in a lymph node.

New atomic-level model helps explain how SARS-CoV-2 causes extensive lung damage

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have published the first detailed atomic-level model of the SARS-CoV-2 "envelope" protein bound to a human protein essential for maintaining the lining of the lungs.

Scientists use an original approach to resolve the 3D structure of flaviviruses

In a recent study, Australian scientists used an original approach to resolve the 3D structure of flaviviruses with an unprecedented level of detail, identifying small molecules known as 'pocket factors' as new therapeutic targets.

Penn State researchers develop a way to study microenvironment of breast cancer in 3D

Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue of their host. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells.

Novel method provides faster and more precise diagnostics in histopathology

Histology is the study of biological tissues at a microscopic level. Also called microscopic anatomy, histology is widely used to provide diagnosis of cancer and other diseases.

New platform helps non-experts use AI to analyze microscopy images

A new, freely available platform helps non-experts use artificial intelligence to analyze microscopy images. The platform has been developed at Åbo Akademi University in Finland and Instituto Gulbenkian de Ciência, Portugal, and will be of big help in research and diagnostics using modern day microscopes.

New imaging technique captures movies of receptors on the surface of living cells

A new imaging technique developed by scientists at Columbia University Vagelos College of Physicians and Surgeons and St. Jude Children's Research Hospital captures movies of receptors on the surface of living cells in unprecedented detail and could pave the way to a trove of new drugs.

Study shows how proteins work in concert to resolve DNA double-strand breaks

From cancer treatment to sunlight, radiation and toxins can severely damage DNA in both harmful and healthy cells. While the body has evolved to efficiently treat and restore damaged cells, the mechanisms that allow this natural repair remain misunderstood.

Scientists illuminate how some antibodies can effectively disable ebolaviruses

Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses--and now, scientists at Scripps Research have illuminated how these antibodies can disable the viruses so effectively.

A novel method to visualize protein channels in bacteria

Almost all bacteria rely on the same emergency valves--protein channels that pop open under pressure, releasing a deluge of cell contents.

Tiny SARS-CoV-2 protein may have big implications for future COVID-19 treatments

A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers.

Real-time imaging shines light on the coordination of neural stem cell activation

In all adult vertebrates, neural stem cells can be recruited to produce new neurons in the brain. However, little is known about these so-called "activation" processes.

Scientists use cryo-electron microscopy to unravel how 'guardian' of the genome works

Scientists from the Genomic Integrity and Structural Biology Group led by Rafael Fernández-Leiro at the Spanish National Cancer Research Centre have discovered how certain proteins ensure the repair of errors introduced into the DNA during its replication.
