COLUMBUS, Ohio - If you've watched a slasher movie, you've probably been exposed to the final girl trope - a closing scene of a white, suburban teenage girl who triumphed over a threatening monster and lived to tell the tale. But her story doesn't stop there - in some ways, a whole new life, overshadowed by trauma, has only just begun, Ohio State University graduate student Morgan Podraza posits in an article published in the journal Horror Studies. Consider actor Jamie Lee Curtis' depiction of Laurie Strode in the Halloween film released in 2018, 40 years after her friends were murdered by Michael Myers on Halloween night. ...

East Hanover, NJ. May 28, 2021. An international team of multiple sclerosis (MS) experts has identified four under-researched areas that are critical to advancing symptom management for progressive MS, recommending interdisciplinary collaboration among scientists, clinicians, industry leaders, and those with progressive MS. Their call to action was published in Multiple Sclerosis Journal on March 15, 2021, in the article "Prioritizing progressive MS rehabilitation research: A call from the International Progressive MS Alliance" (doi: 10.1177/1352458521999970). The Alliance was represented ...

The findings have been published in "Science", the renowned journal. The world market for electroceramics is in the region of 25 billion euros a year. These very small components are often not even perceived in daily life. A smartphone alone contains 600 capacitors, 3 trillion - that's 3000 billion - of which are manufactured every year. The way many electroceramics function is not based on current flow through the material, but on small charge dislocations, called polarisation, over fractions of an atomic diameter. About a quarter of the electroceramics produced in the world link this polarisation to an extension of the material, ...

UNIVERSITY PARK, Pa. -- Developing new ultrathin metal electrodes has allowed researchers to create semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices, said an international team of scientists. The research represents a step toward developing completely transparent solar cells. "Transparent solar cells could someday find a place on windows in homes and office buildings, generating electricity from sunlight that would otherwise be wasted," said Kai Wang, assistant research professor ...

As the cleanest renewable energy, hydrogen energy has attracted special attention in the research. Yet the commercialization of traditional proton exchange membrane fuel cells (PEMFCs), which consume hydrogen and produce electricity, is seriously restricted due to the chemical reaction of PEMFCs cathode largely relies on expensive platinum-based catalysts. A solution is to change the acidic electrolyte of PEMFCs to alkaline. Such fuel cells are called anion exchange membrane fuel cells (AEMFCs), and they allow for the use of cheaper metal elements like Co, Ni or Mn to design electrocatalysts. The research team led by Prof. GAO Minrui from University of Science and Technology ...

During the era of commercial whaling, fin whales were hunted so intensively that only a small percentage of the population in the Southern Hemisphere survived, and even today, marine biologists know little about the life of the world's second-largest whale. That makes the findings of researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and the Johann Heinrich von Thünen Institute for Sea Fisheries, which show that a large number of the baleen whales regularly frequent the krill-rich waters surrounding Elephant Island, all the more welcome. Evidence for this is provided by underwater sound ...

An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group at Pompeu Fabra University, has advanced in the understanding and preservation of archaeological sites and in improving their analysis and surveying, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a rapid, inexpensive, non-invasive procedure, which enables generating an additional archaeological record from the anthropogenic deposit by analysing chemical elements, combined with geostatistics. It is a rapid, inexpensive, non-invasive procedure, ...

The work was conducted under the auspices of the Russian Foundation for Basic Research and organizations-participants of the BRICS framework program in science, technology and innovation; the grant title is "Nanosized peptide-based biomaterials for photodynamic diagnostics of tumors". Project lead, Chief Research Associate of KFU's Bionanotechnology Lab Rawil Fakhrullin commented on the results, "The development of materials for theranostics (simultaneous early diagnosis and therapy of diseases) is one of the most urgent tasks in modern chemistry and biomedicine. A feature of such materials is the combination of at least two functions: sensory and therapeutic. ...

A research group led by Takashi Saito, of the Ehime University Graduate School of Medicine, developed a 2-photon excitation light-sheet fluorescence microscope which (1) lowers phototoxicity, (2) extends the field of view, and (3) heightens spatial resolution. This microscope, when used for the observation of medaka fish, made it possible to observe the whole body of the embryo (an extended field of view) at a cellular level resolution (high spatial resolution) without affecting the growth of the fish (low phototoxicity) over a three-day span of embryonic development. ...

The study's senior author, Balfour Sartor, MD, Midget Distinguished Professor of Medicine, Microbiology and Immunology, Co-Director of the UNC Multidisciplinary IBD Center, said the results are encouraging for future use treating Crohn's disease and ulcerative colitis patients. "The idea with this treatment is to restore the normal ...

Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei at about 34TeV for the first time. This work was based on measurements data of the helium spectrum with kinetic energies from 70 GeV to 80 TeV (17.5 GeV/n to 20 TeV/n for per nucleon) recorded by the DAMPE. The relevant results were published in Physical Review Letters. Galactic cosmic rays (GCRs) offers important ways to deeply understand the astrophysical particle origin and accelerators and the interstellar medium of the Galaxy. Helium nuclei, the second most abundant nuclear element of cosmic rays, is a distinguishing feature of space. As for GCRs, the energy spectrum is supposed to follow a negative power law distribution when energies are below the "knee" (at ...

By putting a piece of soft, strain-sensing sheet on the skin may be able to detect skin disorders non-invasively and in real-time very soon. A research team co-led by a scientist from City University of Hong Kong (CityU) has designed a simple electromechanical device that can be used for deep tissue pathology diagnosis, such as psoriasis, in an automated and non-invasive fashion. The findings will lay a foundation for future applications in the clinical evaluation of skin cancers and or dermatology diseases. The research is co-led by Dr Yu Xinge, Assistant Professor from CityU's Department of Biomedical Engineering, and scientists from and Northwestern University in the US. Their findings have been published in the science journal Nature Biomedical Engineering, titled "Miniaturized ...

New Haven, Conn. -- The ancient burrowers of the seafloor have been getting a bum rap for years. These prehistoric dirt churners -- a wide assortment of worms, trilobites, and other animals that lived in Earth's oceans hundreds of millions of years ago -- are thought to have played a key role in creating the conditions needed for marine life to flourish. Their activities altered the chemical makeup of the sea itself and the amount of oxygen in the oceans, in a process called bioturbation. But did that bioturbation help or hinder the expansion of complex animal life? A new Yale study, published in the journal Earth and Planetary Science Letters, found that ...

New Haven, Conn. -- When San Francisco voters overwhelmingly approved a ballot measure banning the sale of flavored tobacco products in 2018, public health advocates celebrated. After all, tobacco use poses a significant threat to public health and health equity, and flavors are particularly attractive to youth. But according to a new study from the Yale School of Public Health (YSPH), that law may have had the opposite effect. Analyses found that, after the ban's implementation, high school students' odds of smoking conventional cigarettes doubled in San Francisco's school district relative to trends in districts without the ban, even when adjusting for individual demographics and other ...

This new 3D effect can be the foundation for topological quantum phenomena, which are believed to be particularly robust and therefore promising candidates for extremely powerful quantum technologies. These results have just been published in the scientific journal Nature Communications. Dr. Tobias Meng and Dr. Johannes Gooth are early career researchers in the Würzburg-Dresdner Cluster of Excellence ct.qmat that researches topological quantum materials since 2019. They could hardly believe the findings of a recent publication in "Nature" claiming that electrons in the topological metal zirconium pentatelluride (ZrTe5) move only in two-dimensional ...

WHAT: An environment in which family members support one another and express their feelings can reduce the effects of social deprivation on cognitive ability and development among adopted children, suggests a small study by researchers at the National Institutes of Health. In contrast, rule-driven households where family members are in conflict may increase an adopted child's chances for cognitive, behavioral and emotional difficulties. The study was conducted by Margaret F. Keil, Ph.D., and colleagues in the Section on Endocrinology and Genetics at NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). It appears in Pediatric Research. Researchers enrolled children who had spent at least eight ...

An analysis led by North Carolina State University researchers found counties with more socially vulnerable populations had a higher density of natural gas pipelines overall. The findings suggest counties that are more socially vulnerable are also at greater risk of facing water and air pollution, public health and safety issues, and other negative impacts associated with the pipelines. "We know that the network, as it stands today, is already distributed in such a way that any negative impacts fall disproportionately on vulnerable communities," ...

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it. Despite their widespread use, hormonal contraceptives are known to increase the risk of breast cancer, which is the most common cause of cancer-related death among women worldwide, and also topped the list of most commonly diagnosed cancers in 2020. The main component of hormonal contraceptives are progestins, ...

Anesthesia may be an exact science, but it's not yet fully personalized. Anesthesiologists use a variety of methods to calculate the right dose for a given patient: clinical studies, medical databases and laboratory measurements, for example. However, every individual responds to anesthetics in a different way, and there's no way of knowing what that response will be until the anesthetic is administered. Personalizing dosage Today patients often receive supplemental doses of an anesthetic during their operation based on their reaction. The role of anesthesiologists is to make sure that a patient doesn't wake up too soon and has no memory of the procedure, but they must use ...

Scientists from the Wellcome Sanger Institute and the University of Cambridge found that in children with neuroblastoma - a cancer of immature nerve cells - treatment with platinum chemotherapy caused changes to the genome that could then cause leukaemia in some children later on. The findings, published 27th May 2021 in Blood could lead to an ability to identify which children are more likely to develop the secondary cancer. This in turn could lead to changes in their treatment plan to either avoid these risks or take measures to prepare. Secondary blood cancer is a challenging complication of childhood neuroblastoma cancer treatment. Every year around 100 children in the UK are diagnosed with neuroblastoma*, ...

The group of experts includes Professor and Academician of Tallinn University of Technology Jarek Kurnitski, who said that improving ventilation can be regarded more broadly as a paradigm shift equal in scale to the transformation in the standards of drinking water supplies and food hygiene. "There has long been no doubt that you can get infection when you drink water or eat food that has been contaminated. Now we must work towards providing clean air so we can breathe safely," Kurnitski said. He added, "Researchers see updating of ventilation standards, ventilation requirements based on the probability of infection and more efficient and flexible ventilation systems as a solution. High air change rates are required only in the event of an epidemic, at any ...

Varying immune response to vaccinations could be countered with microbiota-targeted interventions helping infants, older people and others to take full advantage of the benefits of effective vaccines, Australian and US experts say. A comprehensive review in Nature Reviews Immunology concludes that evidence is mounting in clinical trials and other studies that the composition and function of individuals' gut microbiota are "crucial factors" in affecting immune responses to vaccinations. "Never before has the need been greater for robust and long-lasting immunity from our vaccination programs, particularly in low and middle-income countries, and for populations at increased ...

Researchers at the University of Adelaide are concerned video sharing platforms such as YouTube could be contributing to the normalisation of exotic pets and encouraging the exotic pet trade. In a study, published in PLOS ONE, researchers analysed the reactions of people to videos on YouTube involving human interactions with exotic animals and found those reactions to be overwhelmingly positive. The researchers analysed the reactions - via text and emoji usage - in comments posted on 346 popular videos starring exotic wild cats and primates in 'free handling situations'. These situations involved exotic animals interacting with humans or other animals, such as domestic cats and dogs. The videos examined received ...

Public use of parks and reserves increased only slightly during last year's COVID-19 national lockdown despite gyms and sports facilities shutting down, a University of Queensland study found. UQ School of Biological Sciences PhD candidate Violeta Berdejo-Espinola surveyed 1000 people in Brisbane, measuring their use of urban green space and the benefits people associated with visiting the areas during lockdown. "People all around Brisbane, myself included, noticed a boom in park use in 2020, but while more people ventured into local parks, many folks were left indoors," Ms Berdejo-Espinola said. "Thirty-six ...
