Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by simple and extremely fast polarization measurements. The method opens new possibilities to measure spectral changes on a nanosecond time scale over the entire color spectrum of light.

In a new publication from Opto-Electronic Advances, researchers led by Professor Junsuk Rho from Pohang University of Science and Technology (POSTECH), South Korea consider switchable diurnal radiative cooling by doped VO2.

This model addresses the fact that most traditional climate models effectively ignore cities entirely, causing them to underestimate the frequency and severity of urban heat waves. Urban areas make up only 2-3% of the earth's land, so their effect on global models is negligible, but more than half of the world's population lives in urban areas, so their impact is significant.

RedHill Biopharma Ltd. (Nasdaq: RDHL), a specialty biopharmaceutical company, today announced presentation of the positive Phase 2 safety and efficacy data for oral opaganib (Yeliva®, ABC294640) in hospitalized patients with COVID-19 pneumonia at the World Microbe Forum (WMF) 2021 (poster #: 5574).

Depression in youth, between the ages of 10 and 24 years, is both a leading cause of stress and a possible risk factor for future diseases and impairment. Now, a study in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP) confirms that depression in childhood or adolescence is associated with higher levels of adult anxiety and substance use disorders, worse health and social functioning, less financial and educational achievement, and increased criminality.

Life expectancy in primate populations is determined by the survival rate of the younger ones.

Acrylamide, which is extensively used in industries, causes peripheral neuropathy or encephalopathy. Now, scientists from Japan examined the response against oxidative stress in acrylamide-induced neurotoxicity and found that nuclear factor erythroid 2-related factor 2 (Nrf2), a master regulator of the immune system and response to oxidative stress, was at the center of this toxicity. They found that Nrf2 plays a protective role by increasing the expression of protective genes and decreasing that of pro-inflammatory genes.

Helsinki University research group used live tissue imaging for the first time to visualise the emergence of the mammary gland.

Researchers found a portion of the extracellular messenger RNA (mRNA) are taken up by natural killer cells (NK cells) expressing the mRNA receptor protein and has a function in the cell.

Led by Dr. Bassam Janji, from the Luxembourg Institute of Health, the team used gene editing technologies to show how targeting HIF-1α could not only inhibit tumor growth, but also drive cytotoxic immune cells to the cancer tissue. This discovery provided a valuable new target to make resistant melanomas more vulnerable to available anti-cancer treatments. Their findings were recently published in the reputable Oncogene journal.

Summer holiday school catch-up programs to address gaps in knowledge after school closures need to support children who are still struggling due to social isolation.

When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluorescence images from live cells, researchers at the University of Zurich have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage.

A blood test that can detect tiny amounts of circulating cancer DNA may be able to identify risk of cancer recurrence and guide precision treatment in bladder cancer following surgery, according to a clinical study led by Professor Tom Powles from Queen Mary University of London and Barts Health NHS Trust.

Researchers from the German Center for Infection Research (DZIF) at Charité - Universitätsmedizin Berlin and the University of Bonn have examined the way in which SARS-CoV-2 reprograms the metabolism of the host cell in order to gain an overall advantage. According to their report in Nature Communications, the researchers were able to identify four substances which inhibit SARS-CoV-2 replication in the host cell.

In joint research, POSTECH professor Inhwan Hwang develops a new avian influenza vaccine using plant-based recombinant protein.

A study by the University of Liverpool has shown that while asymptomatic COVID-19 testing in Liverpool was popular, significant inequalities were evident between those who got tested and those who didn't.

Drugs routinely used during fertility treatments to release eggs do not increase the risk of developing breast cancer, new research has shown.

Scientists studying a common childhood cancer have made a major breakthrough which could lead to a cure for some youngsters who would not have survived the condition.

In the mid-2030s, multiple United States coastal regions may see rapid increases in the number of high-tide flooding (HTF) days, according to a study led by the University of Hawai'i at Mānoa and published today in Nature Climate Change. The combined effects of sea-level rise and natural fluctuations in tidal range are anticipated to cause tipping points in the frequency of HTF.

An ongoing international Alzheimer's clinical trial has found that one drug, gantenerumab, improved biomarkers of disease despite unclear cognitive effects, prompting study leaders to offer participants the option of continuing to receive the drug and participate in follow-up examinations as part of a so-called open label extension.
