Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter.

Cold plasma inactivates SARS-CoV-2

In one such effort, Zhitong Chen et al., in a recent medRxiv* preprint paper find that by employing an efficient cold atmospheric plasma (CAP) with argon feed gas on different surfaces inactivates the infectious SARS-CoV-2 virus.

Magnetic resonance spectroscopy helps distinguish brain energy molecules

Researchers at Center for BrainHealth®, part of The University of Texas at Dallas, recently examined how cells in the brains of people at risk for developing Alzheimer's disease make and use energy.

Consumption of cooked carrots can also trigger allergic reactions, finds study

The consumption of raw carrots triggers allergic reactions in many people. Contrary to popular belief, cooked carrots can also have this effect.

Researchers try and pop SARS-CoV-2 with an AFM tip - virion surprisingly resilient

Researchers at Semmelweis University and the National Public Health Center in Hungary have conducted an imaging study showing that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent responsible for coronavirus disease 2019 (COVID-19), is a highly dynamic and resilient virus

Study invalidates Ebselen and other broad-spectrum SARS-CoV-2 Mpro inhibitors

Other novel compounds with Mpro inhibitory activity have also been claimed to have antiviral activity. These include ebselen, disulfiram, tideglusib, carmofur, shikonin, and PX-12. A new research paper discusses the role of these molecules as potential Mpro inhibitors in the prevention of SARS-CoV-2 infection.

Hannover and Rostock team up to develop non-invasive optical melanoma diagnostics

Leibniz University Hannover and Rostock University Medical Center receive funding for the development of non-invasive optical melanoma diagnostics.

Brain activity during passive tactile stimulation reveals individuals’ hand preferences

Have you ever wondered whether the brains of right-handed people work differently from those of left-handers? Is it possible to distinguish between them by observing their brain activity in response to stimuli or tasks?

3D printed nanoparticle biosensing platform detects SARS-CoV-2 antibodies within seconds

Pandemics caused by novel infectious agents like the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), Zika, or Ebola virus seriously impact human health and lives while also overwhelming health care systems all over the world. Early detection and diagnosis allow isolation of the infected patients and contact tracing, which can mitigate the spread of the virus and save lives, especially when a significant number of the patients are asymptomatic.

Metabolite signature reveals signs of multi-organ damage in COVID-19 patients

SARS-CoV-2, the virus responsible for COVID-19, can cause a wide range of symptoms, from none at all to severe respiratory stress, multi-organ failure and death.

Research finds different patterns of blood use in the brains of older women with Type 2 diabetes

A University of Houston researcher is reporting that the brains of older women with Type 2 diabetes do not use as much oxygenated blood as those who don't have the disease.

New findings change the understanding of cholesterol’s effects on cellular membranes

For more than a decade, scientists have accepted that cholesterol - a key component of cell membranes - did not uniformly affect membranes of different types.

Using proteins to track SARS-CoV-2 infections through wastewater

A new study published on the preprint server medRxiv* in September 2020 describes the measurement of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proteins in wastewater as a reliable way to track the virus in the community.

Study identifies important regulator of neuron function and survival

Scientists studying neuronal energy metabolism found evidence that the loss of an important energy regulator called AMPK in neural stem cells or glial cells called astrocytes causes neuronal death in laboratory rodents.

Bulky benchtops for fingerprinting drugs could be replaced with a tiny photonic chip

As new infectious diseases emerge and spread, one of the best shots against novel pathogens is finding new medicines or vaccines.

Study may help develop new types of non-addictive pain therapies

A team of scientists from ASU's School of Molecular Sciences and the Biodesign Institute have recently published a study in Nature Communications that helps clarify the contributions to an ion channel's temperature - dependent activation. This in turn should aid in the development of new types of non-addictive pain therapies.

Artificial intelligence method can rapidly and remotely detect fentanyl and derivatives

To help keep first responders safe, University of Central Florida researchers have developed an artificial intelligence method that not only rapidly and remotely detects the powerful drug fentanyl, but also teaches itself to detect any previously unknown derivatives made in clandestine batches.

Researchers study about the science behind staying motivated

There is no question that motivation is one of the hardest and yet important factors in life. It's the difference between success and failure, goal-setting and aimlessness, well-being and unhappiness. And yet, why is it so hard to get motivated - or even if we do, to keep it up?

Fluorescent molecules in urine can help monitor malignant melanoma

What if you could simply provide a urine sample rather than undergo a painful surgical procedure to find out if your cancer was responding to treatment? It may seem too good to be true, but researchers at Pavol Jozef Šafárik University in Košice, Slovakia, have identified fluorescent molecules in urine that may allow patients with malignant melanoma to do just that.

Finned nanoporous catalyst facilitates molecular transport

Thousands of chemical processes used by the energy industry and for other applications rely on the high speed of catalytic reactions, but molecules frequently are hindered by molecular traffic jams that slow them down.

Characteristics of electron emission from irradiated biomolecules

When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions.
