”When pentacene is excited by light, the electrons in the material rapidly react,” explains Prof. Ralph Ernstorfer, a senior author of the study. “It was an open and very disputed question whether a photon excites two electrons directly or initially one electron, which subsequently shares its energy with another electron.” To unravel this mystery the researchers used time- and angle-resolved photoemission spectroscopy, a cutting-edge technique to observe the dynamics of electrons on the femtosecond time scale, which is a billionth of a ...

New multi-institutional phase 3 clinical trial data published May 2 in Cell Reports Medicine found that a cancer stem cell test can accurately decide more effective treatments and lead to increased survival for patients with glioblastoma, a deadly brain tumor. The University of Cincinnati’s Soma Sengupta, MD, PhD, a co-first author of the research and a University of Cincinnati Cancer Center physician-researcher, said the research focused on patients whose glioblastoma had returned after initial treatment.  The trial tested the effectiveness ...

Toronto - Want to make a positive difference in the wage conditions of developing country factory workers churning out products for multinational firms? Paying them more seems an obvious first step. But research looking at the experience of clothing retailer H&M Group suggests a less direct approach — by intervening at the management practice level — can empower workers and significantly raise wages in sustainable ways, multiplying the impact of the company’s investment many times over. In 2013, following activist pressure for reform, H&M went to its suppliers and asked them to voluntarily implement ...

Anomaly detectors are used to distinguish differences between normal and abnormal data, which are usually implemented by evaluating and ranking the anomaly scores of each instance. A static unsupervised streaming anomaly detector is difficult to dynamically adjust anomaly score calculation. To solve the problem, a research team led by Prof. Zhiwen Yu published their new research on 15 April 2023 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature. The team proposed a human-machine interactive streaming anomaly detection method, named ISPForest, which can ...

Sons of women with polycystic ovary syndrome (PCOS) are three times more likely to develop obesity, according to a study published in Cell Reports Medicine. According to the researchers from Karolinska Institutet the findings highlight a previously unknown risk of passing PCOS-related health problems across generations through the male side of a family. PCOS is caused by the ovaries producing too much of the sex hormone testosterone. The disease affects around 15 per cent of women of childbearing age worldwide and is a condition that ...

Embargoed for release: Friday, May 5, 2023, 11:00 AM ET Key points: Among those diagnosed with non-small cell lung cancer—the most common form of lung cancer—current smokers had 68% higher mortality and former smokers had 26% higher mortality compared to never smokers The longer a patient had gone without smoking pre-diagnosis, the more improved their odds of survival were The study is one of few to examine mortality not just among current and never smokers, but also among former smokers—enabling more robust findings about the impacts ...

About The Study: In this study of patients with non–small cell lung cancer, quitting smoking early was associated with lower mortality following a lung cancer diagnosis, and the association of smoking history with overall survival may have varied depending on clinical stage at diagnosis, potentially owing to the differing treatment regimens and efficacy associated with smoking exposure following diagnosis. Detailed smoking history collection should be incorporated into future epidemiological and clinical studies to improve lung cancer ...

About The Study: The findings of this study of 766 patients with SARS-CoV-2 infection suggest that patient-reported perceived cognitive deficits in the first 4 weeks of SARS-CoV-2 infection are associated with post–COVID-19 condition (PCC; colloquially known as long COVID) symptoms and that there may be an affective component to PCC in some patients. The underlying reasons for PCC merit additional exploration.  Authors: Neil Wenger, M.D., M.P.H., of the University of California, Los Angeles, is the corresponding author.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/  (doi:10.1001/jamanetworkopen.2023.11974) Editor’s ...

Adolescents and young adults with advanced heart disease are at high risk of dying in the hospital, often require invasive treatment and experience significant symptoms that impact their quality of life. And while most of their parents prefer that decision making about their treatment and care options remain between parents and physicians, many young people want to be actively involved in medical decisions affecting them, a new study suggests. “As a pediatric psychologist, I have found that healthcare communication is one of the most critical – yet most underappreciated ...

People who perceived that they had cognitive difficulties such as memory problems during COVID were more likely to have lingering physical manifestations of the disease than people who did not report cognitive issues, new UCLA research suggests. More than one in three people experiencing long COVID symptoms perceived such cognitive deficits, which have been found to be related to anxiety and depression. The findings indicate that psychological issues such as anxiety or depressive disorders may ...

A research team led by Dr. WANG Liang from the Institute of Psychology of the Chinese Academy of Sciences has found that right hippocampal theta power hierarchically encodes the distance between the current position and a goal destination. The study was published online on May 5 in Current Biology. Successful navigation to a goal is crucial for animals in nature as well as for humans in modern life. Computational models show that goal-directed navigation computes the Euclidean distance to the goal. Multi-scale representation of goal distance is extremely efficient and less susceptible to interference from background noise than single-scale coding. ...

The language used to communicate fertility awareness should be more empathetic and target both men and women, finds a new study involving UCL researchers. The review, published in Human Reproduction Open, gives five recommendations on how to promote fertility awareness in a more positive way. While education about fertility is not intrinsically controversial, finding the right language to address the topic can be difficult – with the risk of causing negative effects such as anxiety, culpability, and stigma. After reviewing previous studies and literature on the subject, the team were particularly keen to resolve issues around language that could evoke feelings of personal blame, ...

The implementation of effective policies at local and regional level, and the cooperation of all countries in the Mediterranean Sea basin is urgently needed to successfully reverse the environmental problems in this marine area.

Alfalfa (Medicago sativa), commonly called the “King of Grass,” is a legume grown in many parts of the world as a source of animal fodder. It is prized in the forage industry for its high protein content and biomass yield. Recently, alfalfa protein has found applications in aquaculture, pet food industry and human diet. Furthermore, it is seen as an environmentally beneficial crop, with positive impacts on biodiversity and soil nitrogen conservation. Alfalfa produces two seed types—hard and non-hard—with no obvious visible differences. Unfortunately, the hard seeds ...

Lithium-air batteries, also known as lithium-oxygen batteries, are candidates for the next generation of high-energy electricity storage devices. Their theoretical energy storage capacity is ten times that of conventional lithium-ion batteries of the same weight, but they are not yet chemically stable enough to provide a reliable solution. Now a newly launched collaborative research project in which a team from the University of Oldenburg, Germany, led by chemist Professor Dr. Gunther Wittstock is participating is testing ...

Conditions such as coeliac disease and Parkinson’s disease could be detected in principle up to 10 years earlier than they are currently, suggests a new study by UCL researchers. The study, published in the British Journal of General Practice, reviewed existing evidence on how people’s use of healthcare changed in the weeks, months and years ahead of the diagnosis of a range of conditions. This detectable change in healthcare use indicates the condition’s “diagnostic window” – that is, the point at which diagnosis in some patients may theoretically be possible. While ...

Scientists' Hubble Space Telescope observations of the young star, TW Hydrae may signal new planets under construction. In 2017 astronomers reported discovering a shadow sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding the red dwarf star. The shadow isn't from a planet, but from an inner disk slightly inclined relative to the much larger outer disk – causing it to cast a shadow. One explanation is that an unseen planet's gravity is pulling dust ...

Researchers often use simulations when designing new algorithms, since testing ideas in the real world can be both costly and risky. But since it’s impossible to capture every detail of a complex system in a simulation, they typically collect a small amount of real data that they replay while simulating the components they want to study. Known as trace-driven simulation (the small pieces of real data are called traces), this method sometimes results in biased outcomes. This means researchers might unknowingly choose an algorithm that is not the best one they evaluated, and which will perform worse on real data than the simulation predicted that it should.  MIT researchers ...

Art can have a positive effect on our mood. But does this also work when we look at paintings on a screen? An international research team involving the University of Vienna, the Max Planck Institute for Psycholinguistics in Nijmegen and the Max Planck Institute for Empirical Aesthetics (MPIEA) in Frankfurt am Main decided to investigate this question. The study was funded by the EU Horizon ART*IS Project. The results have now been published as an open access article in the journal Computers in Human Behavior. 240 study participants viewed an interactive Monet Water ...
