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 decipher the activation mechanism of a chemokine receptor

Chemokine receptors, located at the surface of many immune cells, play an important role in their function. Chemokines are small proteins that bind to these receptors and control the movement and behavior of white blood cells.

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.

Researchers develop new imaging technique for studying nanoscale coronavirus-host interactions

Lei S. Qi of Stanford University, California, and colleagues published research showing a potential framework to better characterize coronaviruses' biology. While most high-resolution imaging techniques show the life cycle of coronaviruses, identifying viral or host proteins and genomes remains poorly understood. Their results use multi-color super-resolution imaging allows them to study nanoscopic parts of the coronavirus, including RNA.

Local anesthetic procaine inhibits SARS-CoV-2 in vitro

Research has shown that procaine and procaine-hydrochloride can reduce replication of SARS-CoV-2 and influenza A viruses in infected cells and reduce the production of cytokines by the viruses, making them potentially useful for treating COVID-19.

Smoking and vaping increase ACE2 levels and virus spike binding in airway epithelium

A new bioRxiv preprint attempts to make some sense of why certain people experience more severe forms of COVID-19 as compared to others by pointing to the increase in virus binding that occurs in the presence of smoking or vaping.

A closer look at how COVID-19 damages human lungs

A recent study conducted at the United States Department of Energy’s (DOE) Brookhaven National Laboratory provides the first atomic-level detailed model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope protein when bound to human proteins within the lungs. The study was recently published in Nature Communications.

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.

Researchers use a unique approach to document the diet of Neanderthals

Neanderthals, extinct cousins of modern humans, occupied Western Eurasia before disappearing and although it was once thought that they travelled as far east as Uzbekistan, in recent years an international research team with the participation of the University of Valencia discovered that they reached two thousand kilometers further East, to the Altai Mountains of Siberia.

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.

New blood test helps monitor patient’s response to cancer treatment

Cancer patients who are undergoing targeted therapy can look forward to a new blood test that could tell their doctors whether the treatment is working, within one day after the start of the treatment.

MSU research reveals how the skin's immune cells organize themselves to ward off intruders

It can be easy to forget that the human skin is an organ. It's also the largest one and it's exposed, charged with keeping our inner biology safe from the perils of the outside world.

SARS-CoV-2 evades neutralizing antibodies and rapidly spreads by cell fusion, finds study

In a new study by researchers in the UK, Germany and South Africa, this process is visualized using time-lapse microscopy of a human cell lung line, demonstrating that SARS-CoV-2 can induce cell-to-cell fusion within 6 hours post-infection. Further, the application of neutralizing monoclonal antibodies or convalescent plasma was unable to prevent the spread of the virus by this mechanism, suggesting that removing SARS-CoV-2 from cells permissive of cell membrane fusion could be more difficult than other types of cell.
