The UNLV Music Lab (Principal Investigator: Erin Hannon) is conducting a new study about misophonia, ASMR, musicality and emotional responses to meaningful sounds. We are currently recruiting for a research study in which we will ask you questions about which sounds you like
One of the major issues in general relativity that separates it from other descriptions of the universe, like quantum physics, is the existence of singularities . Singularities are points that when mathematically described give an infinite value and suggest areas of the universe where the laws of physics would cease to exist — i.e. points at the beginning of the universe and at the center of black
Researchers at the Broad Institute of MIT and Harvard have developed a new version of prime editing that can install or swap out gene-sized DNA sequences. First developed in 2019, prime editing is a precise method of making a wide diversity of gene edits in human cells, including small substitutions, insertions, and deletions.
Bluetooth-Phobic VP In a classic instance of news-that-shouldn't-be-news news , Vice President Kamala Harris came under fire this week for the outrageous decision to not use Bluetooth headphones. It all began when Politico published a hard-hitting story on Monday about the VP's aversion to the technology, citing numerous examples in which Harris could be seen with wired headphones. The article we
Melting Rock Instead of crushing through rock with a massive grinder, a startup called Petra is hoping to dig tunnels using superheated gas, Wired reports . In 2018, according to the magazine, the company tested the technology in an industrial park in California, heating up the stone to above 10,000 degrees Fahrenheit. Since then, Petra settled on a slightly different method, blasting sheets of r

The drops, called pilocarpine and marketed as Vuity by pharma outfit Allergan, could come to the aid of some 128 million Americans who are nearsighted. According to the company, one drop in each eye can sharpen closeup vision f
Closing Time Well, it's finally happened: Elon Musk is quitting the companies he's helped build to become a full-time influencer. Or at least that's what he claimed in a likely-facetious-but-maybe-also-slightly-self-aware tweet that had more than a few people wondering if he was being serious. "Thinking of quitting my jobs and becoming an influencer full-time [what do you think]," the world's wea
NASA's Mars itty bitty scouting helicopter has outlived its life expectancy seven times over — and when it does finally cross the cosmic rainbow bridge, things are probably gonna get emotional. This heartwrenching insider scoop comes from Christopher Hamilton, an associate professor of planetary sciences at the University of Arizona who's witnessed other tearjerker endings at NASA's Jet Propulsio
Early in the coronavirus pandemic last year, I couldn't help but wonder (sorry) how the characters of Sex and the City might be faring in quarantine. And because those characters were never really human beings so much as personality archetypes entertainingly bundled into couture and thrust into chaotic situations, the imaginary story lines wrote themselves. Carrie, obviously, was calling Miranda

Pluto may be reinstated to its position as a planet — and other celestial bodies may join it. A new study from the Florida Space Institute at the University of Central Florida surveyed centuries of planet literature and found that the decision that led to Pluto's demotion stemmed from extremely old-school ideas that mixed astronomy with astrology — and even folklore — and as such, the decision sh
Steven Spielberg has been making films that feel like musicals for his entire career. No, the fearsome shark of Jaws and dinosaurs of Jurassic Park didn't belt out a tune, and heroes like Indiana Jones and Tintin weren't dancing through their set pieces, but they might as well have been. Spielberg is an expert at the careful choreography of camera blocking; his gift for legibly communicating comp

He chose to capture the moment before the president's entrance, as members of the audience held their
After weeks of waiting, the Supreme Court this morning finally allowed abortion providers' challenge against Texas's functional ban on abortion, S.B. 8 , to go forward . But the win for abortion providers is not the sweeping victory that seemed likely when the Court heard oral argument on S.B. 8 in November —and even if legal abortions resume in Texas, any reprieve probably won't last for long, b
Vacuum Pants A team of scientists have created a tube-like sleeping bag that sucks on lower bodies of astronauts like human-sized popsicles — with the goal of keeping their eyes healthy. The odd contraption is designed to counter one of the most serious medical problems astronauts face when they spend prolonged periods in microgravity: a build up of fluid in the head that can exert pressure on th

B y April 1968, Charles de Gaulle was bored. "None of this amuses me anymore," the French president told his aide-de-camp, Admiral François Flohic. "There is no longer anything difficult or heroic to do." Over the previous decade, de Gaulle had returned from political exile to save the country from military insurrection, killed off the Fourth Republic, created the Fifth, ended the creeping civil
Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible "propagation path" of EM waves and elucidated the mechanism by which EM waves propagate to the ground.
If you've read enough about anti-Jewish bigotry, you've probably noticed that no one can agree how to spell it: Is it anti-Semitism or antisemitism ? Regular readers of The Atlantic know that this publication uses the hyphenated version. But before I came here, I wrote for a Jewish outlet that removed the hyphen. And just this past week, The New York Times acknowledged that it had quietly revised

The loudest, most prominent voices in public life are not always the most influential. Some of the people who leave the most profound impact—the ones who actually shape the thinking of a generation—do so quietly. Fred Hiatt, who died earlier this week, was one of those people. Hiatt was not exactly silent. You may have read his columns in The Washington Post or, before that, his reporting. But he
In recent weeks, two new Ridley Scott films have arrived in theaters. At first glance, House of Gucci and The Last Duel are very different movies: one a true-crime drama about a glamorous family, the other a Rashomon -style retelling of an assault in medieval France. But, fundamentally, both of Scott's new films are about the corruptions of wealth—and the lengths men will go to defend their own p
Interest in vertical farming is growing worldwide. This method of cultivation offers great advantages: local, fresh production that is possible at any location in a very sustainable way. On the negative side are the high electricity consumption and investment costs. Scientists from Wageningen University & Research, together with international colleagues, provide a balanced view of the current situ
Eavesdropping doesn't just belong in the playbooks of police officers and spies. It is also a phenomenon that plays out among animals. Previous studies have shown that certain species, especially birds, listen to each other for warnings of nearby predators. But a new study from the University of Copenhagen reveals that a variety of mammals eavesdrop on one another when it comes to finding food.

A maze is a popular device among psychologists to assess the learning capacity of mice or rats. But how about robots? Can they learn to successfully navigate the twists and turns of a labyrinth? Now, researchers have demonstrated they can. Their robot bases its decisions on the very system humans use to think and act: the brain. The study paves the way to exciting new applications of neuromorphic
Visual search is a workhorse for investigating how attention interacts with processing of sensory information. Attentional selection has been linked to altered cortical sensory responses and feature preferences (i.e., tuning). However, attentional modulation of feature selectivity during search is largely unexplored. Here we map the spatiotemporal profile of feature selectivity…
There are currently no treatments that can slow the progression of neurodegenerative diseases, such as Alzheimer's disease (AD). There is, however, a growing body of evidence that activation of the M1 muscarinic acetylcholine receptor (M1-receptor) can not only restore memory loss in AD patients but in preclinical animal models can…
Cellular homeostasis requires the sensing of and adaptation to intracellular oxygen (O2) and reactive oxygen species (ROS). The Arg/N-degron pathway targets proteins that bear destabilizing N-terminal residues for degradation by the proteasome or via autophagy. Under normoxic conditions, the N-terminal Cys (Nt-Cys) residues of specific substrates can be oxidized by…

Last week, the U.S. Supreme Court heard arguments in Dobbs v. Jackson Women's Health Organization, which is considered by many to be the most significant battle over abortion rights in decades. If the court upholds the Mississippi law or overturns Roe v. Wade altogether, as the justices appeared poised to do, 21 states likely will ban or curtail access to abortions in short order.
Children of Earned Income Tax Credit beneficiaries delayed marriage and first births, according to a new study co-authored by a University of Michigan professor, suggesting the cost-effectiveness of the federal program.
It is a fact that bacteria are increasingly developing antibiotic resistance. Information campaigns have raised awareness among the general public that the main cause of antibiotic resistance is the high 'selection pressure' on bacteria due to massive and inappropriate use of antibiotics in both humans and animals.
The Oxidative Stress and Cell Cycle Research Group at UPF has discovered a mechanism whereby cells under stress conditions stop their polarized growth. The study, published in the journal Cell Reports, was led by Elena Hidalgo and José Ayté, and the first author is Clàudia Salat-Canela.
Known to be fine regulators of gene expression, microRNAs are small molecules that remain particularly stable in biofluids—blood, urine, etc. In humans, these molecules have revealed great potential as prognostic or diagnostic tools for many diseases such as various cancers, strokes, and, particularly, heart attacks. However, few studies have been carried out on their potential as non-invasive bio
In 2020, scientists made global headlines by creating " xenobots "—tiny " programmable " living things made of several thousand frog stem cells. These pioneer xenobots could move around in fluids, and scientists claimed they could be useful for monitoring radioactivity, pollutants, drugs, or diseases. Early xenobots survived for up to ten days. A second wave of xenobots , created in early 2021, s
One of the important factors that need to be taken into account for anaerobic digestion is the lipid content of the organic waste. Indeed, a large quantity of lipids enables more gas to be produced: this is known as the methane potential, however too large a quantity can also inhibit the process. Organic waste is often very heterogeneous and of different origins (e.g., agriculture, food industry a
We now know that the effects of climate change are particularly strong in mountain areas. The substantial impacts on the cryosphere (snow, ice and permafrost) have been well described where changes in glaciers and snow cover are concerned, but our knowledge of how avalanche activity responds to rising temperatures is still incomplete. This is partly because we lack sufficiently long snow-avalanche
Claire Vaye Watkins, the conspicuously named protagonist of Claire Vaye Watkins's latest novel, I Love You but I've Chosen Darkness , knows that her vagina has teeth. Claire mirrors the author in many ways beyond their shared name: They're both writers navigating new motherhood and mourning a father who died when they were young. But those strange teeth—which Claire grows lovingly, in secret—are
Helena Bergsten, Center for Infectious Medicine (CIM) at the Department of Medicine Huddinge, is defending her thesis "Streptococcal and Staphylococcal Tissue Infections: Therapeutic Challenges and Opportunities" on December 17th 2021. Main Supervisor is Professor Anna Norrby-Teglund.
Due to the current energy problems, which encompass high electricity bills, regional tensions among oil and gas producers or the impact of climate change, among others, a rational management of energy consumption is becoming increasingly necessary.
Engineers have developed a lanthanum hexaboride (LaB6) nanowire-based field emission gun that is installable on an aberration-corrected transmission electron microscope (TEM). This combined unit is able to perform atomic resolution observation at an energy resolution of 0.2 eV — the highest resolution ever recorded for non-monochromatic electron guns — with a high current stability of 0.4%.
Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or through a curved wine glass. In experiments, scientists have developed a technique to see these matter wave caustics by placing attractive or repulsive obstacles in the path of a
Researchers have successfully developed artificial intelligence technology that can extract hidden equations of motion from regular observational data and create a model that is faithful to the laws of physics. This technology could enable us to discover the hidden equations of motion behind phenomena for which the laws were considered unexplainable. For example, it may be possible to use physics-
The national and local lockdowns put in place during the COVID-19 pandemic forced many people to re-evaluate the way they lived and worked. Research published in the International Journal of Web Based Communities looks at how different activities were relocated to the virtual world during lockdown and how this affected people's wellbeing and their social interactions.
We all know that Father Christmas would struggle to deliver presents to everyone around the world without the help of his magical reindeer. But why were they chosen to pull the sleigh rather than any other animal?
People involved in community-led housing (CLH) are significantly less likely to feel lonely than people living in more conventional homes and neighborhoods, according to a new report by researchers from the universities of Bristol, Lancaster, Northumbria and the London School of Economics and Political Science (LSE), released today (Tuesday 30 November).
Mobbning är inte lika vanligt i klasser där elever tror att deras klasskamrater utan undantag tycker att mobbning är fel, att den som utsätts far illa och att de som mobbar inte kan skylla ifrån sig. Det visar en studie från Linköpings universitet som undersökt hur stor tendens skolklasser har att frikoppla sig från moraliskt ansvar, genom ett så kallat moraliskt disengagemang. Mobbning är inte e
Catalysts are important additives that are used to increase the material and energy efficiency of chemical reactions and processes. Although catalysts operate in cycles that should restore their initial activity over and over again, they do deactivate over time. Researchers from Utrecht University and University of Twente have now developed a powerful analytical tool that marks dead catalyst parti
The use of plastics on a daily basis is inherent to modern life. The most produced and utilized family of plastics are polyolefins, which are used in packaging materials, toys, lawn chairs, and extremely strong fibers and ropes. During his Ph.D. research, Simon Houben investigated how the properties of polyolefins can be changed for use in new applications such as water purification, separation of
Almost 80 years after Scottish botanist Robert Brown described the continuous random motion of microscopic particles in a fluid, Albert Einstein provided a theoretical foundation for this observation. Since then, scientists have discovered systems that deviate substantially from the laws of Brownian motion. Such deviations are referred to as anomalous diffusion and occur in a wide range of systems
A new app is giving citizens the power to help scientists understand drying river networks. Developed by the EU-funded DRYvER project, the DRYRivERS app enables citizens to map and report drying cases in rivers and streams.
Researchers have introduced the idea of "democracy by deterrence" and show how it might be weakening in the United States. American democracy is in crisis —a majority of scholars and the public agree. Allegations of unfair voting practices, such as voter suppression and gerrymandering, abuses of executive power, and mounting concerns about the legitimacy of elections have become a regular occurre
A new kind of new saber-toothed predator was hiding in plain sight. The fossil specimen, unearthed in Wyoming, was on display for decades at the Smithsonian National Museum of Natural History in Washington, DC. When it went off-exhibit in 2017 during a museum renovation, University of Oregon graduate student Paul Barrett finally got a closer look. The animal had long, sharp, saber-shaped teeth, b
The United States should undertake a major research program into how the oceans could be artificially harnessed to remove carbon dioxide from the air, says a new report from the National Academies of Sciences, Engineering, and Medicine.
When you think of migration, you probably won't immediately think of dating apps. Yet such apps are important to many migrants, such as those who identify as lesbian, gay, bi, trans, queer or questioning (LGBT+). Researcher Andrew DJ Shield studied the role that dating apps play in the migration process, and discovered that these online cultures provide more than just a space to flirt. Migrants mi
Exactly 100 years ago tomorrow, a bird that had been relegated to extinction made a comeback. The exquisitely beautiful paradise parrot was rediscovered by Cyril Jerrard, a grazier from Gayndah in Queensland's Burnett district, on December 11, 1921.
Brittany Higgins's disclosure of an alleged rape in our nation's most prominent workplace put all Australian employers on notice—they too must act to end violence against women and better support victim-survivors of domestic and family violence (DFV).
In the history of space exploration, a handful of missions have set new records for ruggedness and longevity. On Mars, the undisputed champion is the Opportunity rover, which was slated to run for 90 days but remained in operation for 15 years instead. In orbit around Mars, the honor goes to the 2001 Mars Odyssey, which is still operational 20 years after it arrived around the Red Planet.
Research in Bangladesh reported in the International Journal of Social Entrepreneurship and Innovation suggests that social entrepreneurship increased there during the COVID-19 pandemic. Areas that benefited from this activity were primarily in food, healthcare, employment, and education, the team writes. They suggest that managers should focus on these four sectors when we are faced with the next
A new study published in PLOS ONE and co-authored by researchers at the Massachusetts Institute of Technology (MIT) and Portland State University (PSU) provides addiitional evidence that spatial proximity increases cross-disciplinary collaboration among researchers.
Turkish ichthyologists have rediscovered populations of the critically endangered Batman River loach in two streams in southeast Turkey, the first time the tiny fish has been seen since 1974, and the first species rediscovered on Shoal and Re:wild's top 10 most wanted lost fishes list, which launched in June 2021.
Marshall Fisher, the UPS professor of operations, information, and decisions in the Wharton School, describes this fall's supply chain crisis as "the mother of all supply chain disruptions." But he also emphasizes one particular point that sometimes gets lost in the narrative: These disruptions are typical.
A team of WEHI researchers has for the first time visualized a human cell death complex linked to autoimmune and inflammatory conditions, such as inflammatory bowel disease, and injuries associated with excessive cell death.
Sengeafsnit til patienter med samtidig psykiatrisk lidelse og misbrug, der åbnede for godt et år siden, gør en forskel for patienterne, oplever afsnitsledelsen. Der er stadig hyppige genindlæggelser, men flere patienter henvender sig selv og har fundet tillid til afsnittet, hvor de møder samme personale indlæggelse efter indlæggelse.
Nature, Published online: 09 December 2021; doi:10.1038/d41586-021-03724-8 Teams of scientists tested 53 ways to induce people to keep returning to the gym and found that money talks. Plus, why we can't wait for the James Webb Space Telescope and replication chaos in cancer biology.

Tredje bølge med COVID-19 har ramt Kirurgisk Afdeling på Sjællands Universitetshospital, Køge, hårdt. Det normale afsnit til planlagt kirurgi huser nu udelukkende COVID-19-patienter. Selvom afdelingen kan trække på tidligere erfaringer, så presser tredje bølge fagligheden, mens ventelisterne stiger, og patienter med udskudte operationer bliver dårligere.
Der er en helt anden ro over forberedelserne til den anden COVID-19-vinter i Danmark på Afdeling for Infektionssygdomme på Aarhus Universitetshospital. Hvis blot coronavirus opfører sig nogenlunde som i de første bølger, har ledende overlæge Lars Østergaard nemlig erfaringen at trække på, når det kommer til planlægning, behandling og arbejdsmiljø.
Der er stadig mange ubekendte for lungemedicinerne, der ikke kun skal have deres øje på COVID-19, men også på kronikere, der bliver mere syge i et åbent samfund, og på influenza. Ulla Møller Weinreich, forskningsansvarlig overlæge på Lungemedicinsk Afdeling på Aalborg Universitetshospital, er alligevel tryg, fordi hun ved, at organisationen kan omstille sig lynhurtigt.
Personaleflugt, lukkede senge, COVID-19-patienter og flere patienter med andre alvorlige sygdomme kan blive en barsk cocktail i de kommende måneder på landets intensivafdelinger. Det forudser Nanna Reiter, overlæge på Intensiv terapiafsnit, Bispebjerg og Frederiksberg Hospital.
Vi er skuffede og vrede over, at Lægeforeningen og Lægernes Pension afviser at ændre i den pensionsordning, som betyder, at kvindelige læger meldt ind før 1998, får op til 10 pct. mindre udbetalt årligt end mænd. I stedet fortsætter man med åbenlyst at kønsdiskriminere sine kvindelige medlemmer.
Sundhedsvæsenet har brug for permanente, ikke midlertidige løsninger som den coronavinterpakke, Folketinget netop har vedtaget som en del af næste års finanslov. Skuffende er det også, at der ikke er afsat penge til psykiatrien. Til gengæld er aftalen godt nyt for de omkring 1.300 udenlandske læger, der ønsker at arbejde i Danmark.
Ever since the day I heard about Facebook's new 'Metaverse', I've been so skeptical and against the fact that someday, humans will be fully immersed in a virtual world with almost little to no social interaction at all in the real world. This is even more concerning coming from the ideology of a man who seems to have no sense of empathy or actual interest in the well being of those using his prod
Citizen scientists have discovered a new object orbiting a Sun-like star that had been missed by previous searches. The object is very distant from its host star — more than 1,600 times farther than the Earth is from the Sun — and is thought to be a large planet or a small brown dwarf, a type of object that is not massive enough to burn hydrogen like true stars.
Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible 'propagation path' of EM waves and elucidated the mechanism by which EM waves propagate to the ground.
New research explores how family dynamics factor into whether 18- to 25-year-olds share private health information and involve their parents when making medical decisions. Having open and respectful conversations and reciprocal information sharing early on could help improve an emerging adult's overall health.
Scientists have demonstrated that modifying an enzyme produced by the bacterium that causes anthrax can protect mice from infection with the deadly disease. Their findings suggest a potential therapeutic strategy for treating multidrug-resistant strains of anthrax, and could lead to new treatments for other bacterial infections.
Hi, I am currently conducting an experiment to examine language processing in adults aged between 50-65 years. It is quite simple and takes approx. 10-15 minutes to complete on a laptop or PC only. Participants must also be right-handed and speak English as a first language. The experiment has received ethical approval from Maynooth University`s Research Ethics Subcommittee (SRESC-2021-2450172).
Our Milky Way's central black hole has a leak. This supermassive black hole looks like it still has the vestiges of a blowtorch-like jet dating back several thousand years. NASA's Hubble Space Telescope hasn't photographed the phantom jet but has helped find circumstantial evidence that it is still pushing feebly into a huge hydrogen cloud and then splattering, like the narrow stream from a hose a
A new study finds that aiming to wait just 60 seconds to clamp the umbilical cord of very premature babies at birth continues to have benefits two years on – decreasing the child's risk of death or major disability.
A study finds that there is a 50 percent chance that the common ancestor of birds and dinosaurs had bright colors on its skin, beaks and scales, but 0 percent chance that it had bright colors on its feathers or claws.
Rove beetles are among the chemists of the insect world, concocting noxious compounds within their bodies that are weaponized to ward off predators, enabling the beetles to survive in leaf litter and soil in ecosystems across the planet. Investigators studying a species of rove beetle report how two distinct cell types have come together to form a specialized gland for making and secreting these d
Researchers train a neural network to estimate — in just a few seconds — the precise characteristics of merging black holes based on their gravitational-wave emissions. The network determines the masses and spins of the black holes, where in the sky, at what angle, and how far away from Earth the merger took place.
Researchers have uncovered a process in the swirling masses of plasma surrounding black holes and neutron stars that can cause previously unexplained emissions of light and heat. These findings can increase basic understanding of fundamental astrophysical processes throughout the universe.
Gut bacteria are both positively and negatively influenced by common medicines, new research shows. Medications that lower cholesterol and blood pressure are associated with a healthier composition and function of gut bacteria, while gastric acid inhibitors and antibiotics interfere with health-promoting bacterial communities.
Three in four sepsis survivors experience new-onset memory problems, psychological impairments or physical diagnoses. This also applies to more than half of sepsis survivors under the age of 40 at the time of their discharge from hospital.
Researchers have developed a circuit that produces the high-quality microwave signals required to control quantum computers while operating at temperatures near absolute zero. This is a key step towards moving the control system closer to the quantum processor, which may make it possible to greatly increase the number of qubits in the processor.
Recently I was lucky to spend seven days on a catamaran out at sea with a small group of (COVID-vaccinated) friends. We traveled around the Gulf of California, witnessing truly amazing sights like manta rays jumping out of the water, sea birds diving into the water, and turtles floating along in the swell. This was […]
A new genomics marker tool has been shown to accurately identify tilapia species and tell apart their hybrids, providing a novel resource to help develop aquaculture and empower conservation in Tanzania, Africa. Crucially, the new tool offers a cheaper solution than full genome data analysis — the current approach to monitoring local biodiversity.
