Research out of Drexel University’s College of Engineering suggests that over the next two decades people living in the Schuylkill Watershed, which includes Philadelphia, could experience as many as 82 more days of water shortfalls due to localized weather impacts of climate change. The projections, which account for changes in population, land use, and climate, indicate that — due to more frequent extreme weather events associated with climate change — the watershed may only be able to meet demand about 67% of the time, a drop of 22% from its current reliability. Published in the journal Water, the paper ...

Researchers at National Jewish Health found that Indigenous coal miners may develop disabling black lung disease but are less likely to qualify for medical benefits using currently required lung function standards rather than standards specific to Indigenous populations.  Black lung (also called coal worker’s pneumoconiosis) is a debilitating respiratory illness that can occur several decades after a miner’s first exposure to coal mine dust. Disease severity can be influenced by adequacy of dust controls, medical surveillance programs ...

Researchers at the University of Illinois Chicago have received a $3.12 million National Institutes of Health grant to study whether acupuncture can alleviate chest pain caused by stable angina. Stable angina is defined as predictable chest pain during exertion or when under mental or emotional stress and is a condition that affects millions of Americans.  A large body of research has shown that acupuncture can help mitigate many types of chronic pain. But little is known about its effect on ischemic pain, which is caused when the heart isn’t getting enough oxygen, as is the case with stable angina.  The two-site study will be led by principal investigators Judith Schlaeger, ...

Washington, D.C.—A new study published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology, provides the first characterization of the coral microbiome under hypoxia, insufficient oxygen in the water. The research is an initial step toward identifying potential beneficial bacteria for corals facing this environmental stressor.  The researchers conducted the study because of the increasing awareness of the impact of the microbiome on host health. For example, a healthy human gut microbiome plays key roles ...

A research team at Johns Hopkins Medicine has created and trained a machine learning model to calculate percent necrosis (PN) — or, what percentage of a tumor is “dead” and no longer active — in patients with osteosarcoma, a type of bone cancer. The model’s calculation was 85% correct when compared to the results of a musculoskeletal pathologist. Upon removing one outlier, the accuracy rose to 99%. A post-chemotherapy PN calculation helps provide the patient with a prognosis for survival. For example, a PN of 99% indicates that 99% of the tumor is dead, suggesting chemotherapy was effective and the patient has improved ...

The discharge of organic effluents—biodegradable waste materials from plants and animals—into freshwater bodies is a significant environmental concern, affecting the health and sustainability of these aquatic ecosystems. However, the methods currently available for inspecting water quality are complex and costly. In this regard, researchers from Ritsumeikan University, Japan, have recently developed a self-powered, inexpensive, and floating biosensor for monitoring water quality at the input of freshwater lakes and rivers. This paper was made available online on September 9, 2023, and was published in Volume 200 of the Biochemical Engineering ...

Quantum-based systems promise faster computing and stronger encryption for computation and communication systems. These systems can be built on fiber networks involving interconnected nodes which consist of qubits and single-photon generators that create entangled photon pairs. In this regard, rare-earth (RE) atoms and ions in solid-state materials are highly promising as single-photon generators. These materials are compatible with fiber networks and emit photons across a broad range of wavelengths. Due to their wide spectral range, optical fibers ...

In a world increasingly aware of the environmental challenges posed by microplastics, a pioneering study conducted by Ruxandra Malina Petrescu-Mag from Babes-Bolyai University, and published in PeerJ Life & Environment, sheds new light on the impact of media narratives on public perception and awareness of microplastic risks. Microplastics - tiny plastic particles that pollute both terrestrial and marine ecosystems - have garnered significant scientific, media, and public attention in recent years. However, this study reveals a lack of consensus between the scientific community and the media, particularly when it comes to how ...

New research from the University of Bath shows the European Union’s MiFID II financial market reforms inadvertently reduced research activity and adversely affected liquidity in London’s main stock market but that the impact on London’s less regulated Alternative Investment Market was mitigated by its special adviser rules. The EU’s Markets in Financial Instruments Directive II (MiFID II) from 2018 aimed to improve transparency around research costs, which were previously bundled into brokers’ overall fees to clients. The legislation demanded the fees be ‘unbundled’ to make the hidden costs more explicit ...

SINGAPORE – A large-scale international study spanning three continents, led by researchers from A*STAR’s Translational Neuroscience Programme of the Singapore Institute for Clinical Sciences (SICS) in Singapore, has found that maternal depressive symptoms begin from early pregnancy and can last up to two years after childbirth. While health professionals often emphasise the postpartum stage after childbirth as a high-risk period for the onset of depression, findings from this latest study reveal a different reality – that maternal depressive symptoms can appear from early pregnancy ...

According to a new paper in Oxford Open Climate Change, published by Oxford University Press, the strategies humanity must pursue to reduce climate change will have to include more than reducing greenhouse gases. This comes from an analysis of climate data led by researcher James Hansen. Scientists have known since the 1800s that infrared-absorbing (greenhouse) gases warm the Earth’s surface and that the abundance of greenhouse gases changes naturally as well as from human actions. Roger Revelle, who was one of the early scientists to study global warming, wrote in 1965 that industrialization meant that human ...

Osaka, Japan – When you think of Japan in the age of COVID, you might imagine a crowd of people wearing masks. But why do so many Japanese people wear masks? In an article published this month in the International Journal of Disaster Risk Reduction, a researcher from Osaka University analyzed mask use before and after the government of Japan downgraded the legal status of COVID-19. Results showed that many people continue to wear masks for socio-psychological reasons – including reasons related to ‘relief’ and ‘norm’. Of course, the obvious motivation for mask use is disease prevention. In the first ...

Regular and moderate physical activity can significantly improve the quality of life of people with internal diseases such as cancer and depression. Unfortunately, many people with internal disorders cannot sufficiently participate in exercise training for several reasons. For example, they often do not have access to appropriate exercise training programs, have a high therapeutic burden, fatigue, or simply no time to engage in physical activity. Accordingly, the Sports Medicine research group led by Professor Perikles Simon at Johannes Gutenberg University Mainz (JGU) investigates how physical activity can be promoted and integrated into patients' daily lives by applying digital tools ...

Arlington, Va. — November 2, 2023 — A new study published today in the American Journal of Infection Control (AJIC) reveals that the use of doxycycline may help protect against Clostridioides difficile (C. diff) infection for some patients with pneumonia. Specifically, study authors found that for hospitalized patients with community-acquired pneumonia who had experienced C. diff infections in the prior year, the use of doxycycline, instead of the more commonly used azithromycin, reduced the development ...

Orlando, Fla - If you’ve ever seen a movie or TV show in which a character has a seizure, you probably have a fairly standard mental picture of someone falling to the ground in full body convulsions while foaming at the mouth. But that doesn’t necessarily reflect reality. A new national survey by Orlando Health finds that while most Americans recognize those classic symptoms of what’s called a generalized tonic-clonic seizure, the majority fail to recognize the subtle signs, all of which can be dangerous and have a profound ...

Cardiovascular diseases (CVDs) continue to rank as the top killer in the modern world. This deadly disorder often starts with the buildup of lipid deposits or plaques within the blood vessel, silently setting the stage for atherosclerosis. Rupture of these atherosclerotic plaques, however, could clot blood vessels and lead to life-threatening conditions including heart attack or stroke. Dyslipidemia, meaning having too much “bad” or atherogenic lipids in the blood, represents the most common cause of CVDs and ...

The research was published in the prestigious journal Nature Communications on 25 August 2023. Breast cancer is a serious concern for individuals with BRCA2 mutations, ...

A growing recognition of the health impact of social risks – such as food insecurity and homelessness – has prompted researchers, healthcare providers and policymakers to consider ways to address these risk factors as part of holistic clinical care. However, some healthcare providers worry the same interventions designed to help patients and families with social risks might also make them feel singled out or like they are otherwise stigmatized. Now, new results of a rigorous study from the University of Chicago Medicine published October 2023 in JAMA Pediatrics suggest well-designed interventions that address social risks can be provided ...
