HJERNENS GLIA-CELLER SKAL STUDERES NÆRMERE: Until now scientists mostly focus on neurons, when trying to understand how the brains work. In recent discoveries they found out that another cell – glial cells – were discovered to have repair and brain plasticity functions. Because previously these cells were not researched, we don't know how many types and functions they have. The researchers are planning on experimenting to understand how these cells react to different stimulus in different parts of the brain.
Researchers warn that UK's most widely established variant may be mistaken for milder illness Coronavirus – latest updates See all our coronavirus coverage Headaches, a sore throat and a runny nose are the most common symptoms associated with the UK's most widely established Covid variant, researchers have said. The data, collected as part of the app-based Zoe Covid symptom study , suggests that
Breaking the Standard Model Researchers may have discovered a giant arc of galaxies that would challenge the standard model of cosmology. The team of astronomers believe that the arrangement of galaxies, which they've dubbed "the Giant Arc," stretches 3.3 billion light years across space, according to Science News . If this is the case, it directly challenges the accepted notion that matter in th
By the time Republicans and centrist Democrats had united late last week to scold Representative Ilhan Omar for a tweet—one of the few pastimes that still draw the two parties together, and something those selfsame chiders would doubtlessly decry, under different circumstances, as cancel culture or censorship —it no longer mattered what, exactly, Omar had said. They had already managed to make a
A new method estimates the ancient megalodon shark was as long as 65 feet. The megalodon was one of the largest fish that ever lived. The new model uses the width of shark teeth to estimate its overall size. A Florida student figured out a way to more accurately measure the size of one of the largest fish that ever lived – the extinct megalodon shark – and found that it was even larger than previ
Using the LOw Frequency ARray (LOFAR) and the Very Large Array (VLA), astronomers have conducted radio observations of a galaxy cluster known as ClG 0217+70 and obtained important information regarding giant radio sources in this cluster; one of them appears to be the most extended radio relic so far identified. The finding is reported in a paper published June 1 on arXiv.org.
Solar physicists around the world have long been searching for satisfactory explanations for the sun's many cyclical, overlapping activity fluctuations. In addition to the most famous, approximately 11-year "Schwabe cycle", the sun also exhibits longer fluctuations, ranging from hundreds to thousands of years. It follows, for example, the "Gleissberg cycle" (about 85 years), the "Suess-de Vries cy
A study led by University of Minnesota Twin Cities researchers uncovered a property of magnetic materials that will allow engineers to develop more efficient spintronic devices in the future. Spintronics focuses on using the magnetic "spin" property of electrons instead of their charge, which improves the speed and efficiency of devices used for computing and data storage.

Researchers from Niigata University, Japan along with their collaborators from Yamagata University have developed a novel and highly efficient nickel sulphide nanowires/carbon nitride based anode for electrocatalytic water splitting applications. The nickel sulphide based anode material has aided in drastically reducing the overpotential of the oxygen evolution reaction. This study holds immense p
By analyzing MRI scans of the foxes, Hecht and her colleagues showed that both the foxes bred to be tame and those bred for aggression have larger brains and more grey matter than the brain of the control group (the foxes not bred for any particular behavior). These findings run in contrast to studies on other animals that have shown domesticated species have smaller brains with less grey matter,
This article was originally published on our sister site, Freethink. Last year, Jennifer Doudna and Emmanuelle Charpentier became the first all-woman team to win the Nobel Prize in Chemistry for their work developing CRISPR-Cas9, the gene-editing technology. The technology was invented in 2012 — and nine years later, it's truly revolutionizing how we treat genetic diseases and even how we produce
High running capacity is associated with health and longevity. However, whether high genetic running capacity promotes more efficient metabolism with aging is not known. A new study reveals that adipose tissue may have a key role in healthy aging.
Farmed foxes selectively bred for tameness and aggressiveness exhibit similar changes to their brain anatomy, according to research recently published in JNeurosci. Both lineages also have larger brains than conventional farm-bred foxes, complicating leading theories on domestication.
Researchers have come up with a way to use one single device – such as a mobile phone or smart watch – to wirelessly power up to 10 wearables on a user. This novel method uses the human body as a medium for transmitting power. Their system can also harvest unused energy from electronics in a typical home or office environment to power the wearables.
The term 'wet market' is often laced with negative undertones, especially in light of the COVID-19 pandemic, but the majority of these markets — like the one featured above in Taipei, Taiwan — pose very little risks to human health and biodiversity, according to a new study.
Nearly 12,000 people in Sweden received sickness benefit from the Swedish Social Insurance Agency for COVID-19 during the first wave of the pandemic. The median duration of sick leave in this group was 35 days, but for many it was considerably more long-drawn-out, according to a University of Gothenburg study.

This is the first such study in humans to show the mechanism of action of this form of drug release. In the future, it will help to increase the effectiveness of drugs and use new active substances for the treatment
Scientists know that developing cells in a healthy embryo will transform into a variety of cell types that will make up the different organ systems in the human body, a process known as cell differentiation. But they don't know how the cells do it.
In 2007, the American housing boom ended, and there was heightened risk of a housing crisis. Private securitizers withdrew from purchasing high-risk mortgages, while government-sponsored enterprises, Fannie Mae and Freddie Mac, dramatically increased their acquisitions of risky mortgages. By 2008, the agencies reversed course, decreasing their high-risk acquisitions.
A new USC study not only sheds light on how the APOE4 gene may cause some of the pathologies associated with Alzheimer's disease, but also suggests a new treatment target that might help people who carry the APOE4 gene in early and late stages of the disease. USC researchers found that APOE4 is associated with the activation of an inflammatory protein that causes a breakdown in the blood-brain bar
Medical University of South Carolina researchers have discovered a gatekeeper protein that destines developing cells in an embryo to become liver cells. It exposes the genetic material of the cells and marks them as 'ready' for differentiation, i.e., transformation into liver cells, when developmental conditions are right. The findings, published in Cell Reports, could help scientists to better un

Research combining systematic observations with cosmological simulations has found that, surprisingly, black holes can help certain galaxies form new stars. On scales of galaxies, the role of supermassive black holes for star formation had previously been seen as destructive—active black holes can strip galaxies of the gas that galaxies need to form new stars. The new results, published in the jou
Many invasive plants are expanding their growing range in response to climate change, making early detection and rapid response more critical than ever. Limited resources, though, can make it impossible to track and manage every range-shifting species.
In a classical second-order phase transition, condensed matter systems acquire long-range order upon cooling below the transition temperature, and the properties near the transition are driven by thermal fluctuations. These behaviors have been long explained by the Landau theory of phase transitions, which leads to the notion of universality, whereby systems with very different microscopic constit
In the field of quantum measurement, weak values, introduced in 1988 by Aharonov, Albert and Vaidman (AAV), represent a most intriguing and puzzling paradigm, with many properties in sharp contrast to traditional (projective) quantum measurements.
The internet era that we live in depends completely on the transfer of vast amounts of information over optical fibers. Optical fibers are literally everywhere. In fact, the overall length of optical fibers installed on our planet is sufficient to reach planet Uranus and back. However, the transfer of information from point A to point B is not enough. The information that we send and receive must
Under vår livstid dricker vi en ansenlig mängd kranvatten. Men en del av de produkter som används för att rena vattnet kan påverka vår hälsa. Det beror på något som kallas för desinfektionsbiprodukter. Klorering används för att förhindra att sjukdomar sprids via dricksvatten, och för att bibehålla vattenkvalitén i hela ledningsnätet. Svenska vattenverk arbetar hårt för att kvaliteten på vattnet s
In the 1960s, Stanley Milgram was sure that good, law-abiding Americans would never be able to follow orders like the Germans in the Holocaust. His experiments proved him spectacularly wrong. They showed just how many of us are willing to do evil if only we're told to by an authority figure. Yet, parts of the experiment were set up in such a way that we should perhaps conclude something a bit mor
Many invasive plants are expanding their growing range in response to climate change, making early detection and rapid response more critical than ever. Limited resources, though, can make it impossible to track and manage every range-shifting species.
Researchers have discovered that differences between the elemental composition of foods and the elemental needs of animals can explain the development of pleasing tastes like salty, umami, and sweet. Taste tells us a lot about foods before they are swallowed and digested, and some tastes correspond with the elemental composition of foods. For example, an aged steak lights up the umami taste recep
Human papillomavirus (HPV) vaccines applied in national vaccination programs protect against most cancers associated with oncogenic, high-risk (hr) HPV types. Two recent studies demonstrate the impact of gender-neutral HPV vaccination in the overall protection against hrHPV infections already with low vaccination coverage.
Quantum critical points are often observed in antiferromagnetic materials, but until recently they were thought to not occur in ferromagnets. CeRh6Ge4 is a recent exception to this paradigm, sparking the search for the origin of this phenomenon. The team from Zhejiang University characterized the electronic structure of CeRh6Ge4 using different techniques, and their findings of localized Ce 4f-ele
To gain a better understanding of SARS-CoV-2 outbreaks involving care homes with fully vaccinated residents, Charité researchers used an outbreak at a Berlin-based facility to analyze virus-related data and the immune responses of elderly residents following vaccination. The data confirm vaccine effectiveness in the elderly, but also indicate a delayed and slightly reduced immune response. The res
Researchers from the University of Tsukuba have designed a cell culture medium that supports the growth and genetic manipulation of hematopoietic stem and progenitor cells without requiring expensive lab equipment. This technique also eliminates the need to irradiate mice prior to transplantation of these cells, making it less toxic to the animals and improving data generation. This method will be
A new infectious disease model that accounts for people's 'level of caution' or 'sense of safety' accurately captures surges and declines in COVID-19 cases since March 2020 — and could help predict how the pandemic will eventually end.
Optical solitons are nonlinear optical wave-packets that can maintain their profile during propagation, even in the presence of moderate perturbations. They offer useful applications in optical communications, all-optical information processing and ultrafast laser techniques.
If you have a good strong trellis, are a bit of a gambler and have a love of kiwifruit, there's no reason not to grow your own crop. As vigorous as they are, though, don't expect to plop these vines into the ground and stand back.

In addition to plaques that accumulate outside of nerve cells in the brain, Alzheimer's disease is also characterised by changes inside these cells. Researchers from the Cell Signalling research group at the Chair of Molecular Biochemistry at RUB, headed by Dr. Thorsten Müller, have been studying what exactly happens in these cells. They determined that various proteins and protein components accu
Researchers from NUS have come up with a way to use one single device – such as a mobile phone or smart watch – to wirelessly power up to 10 wearables on a user. This novel method uses the human body as a medium for transmitting power. Their system can also harvest unused energy from electronics in a typical home or office environment to power the wearables.
Exploration of ocean worlds has become a hot topic of late, primarily due to their role as a potential harbor for alien life. Moons that have confirmed subsurface oceans garner much of the attention, such as Enceladus and Europa. But they may not be the only ones. Uranus' larger moons—Miranda, Ariel and Umbriel could potentially also have subsurface oceans even farther out into the solar system. W
Many butterfly species bear distinct circular markings known as eyespots on their wings, and the functions of these rings of contrasting colors vary. A long-standing theory is that they serve as anti-predator defenses—small eyespots along the wing margin can protect butterflies by directing predators to attack less important parts of the body, such as the hindwings, enabling them to escape.
Cities and nations around the globe are shooting for carbon neutrality, with some experts already talking about the need to ultimately reach carbon negativity. In construction, carbon footprint declarations are used to ease product selection for low carbon building, but these standards don't yet exist for green elements like soil, bushes and plants. A new study led by Aalto University is the first

Eighty-five million. That's how many families— 67 percent of U.S. households —have a pet. If you're one of the many, you probably love your pet an immeasurable amount (maybe you've even considered cloning them) and treat them like family. You want the best for them, from food to bedding to pet insurance , and you'll do just about anything for them. Chewy cares about your pet almost as much as you
One high-profile theory of why people share fake news says that they aren't paying sufficient attention. The proposed solution is therefore to nudge people in the right direction. For example, "accuracy primes"—short reminders intended to shift people's attention towards the accuracy of the news content they come across online—can be built into social media sites.
An international panel is offering a suite of recommendations to prevent the next pandemic—including a new global body of heads of state—but the effort's leaders said more urgent than any single item is concerted international action before the window of opportunity pried open by COVID-19 closes.
The benefits of strict climate policies are often underestimated in public debate, while the costs are generally overestimated, says Lucas Bretschger. Climate protection does not have a negative impact on economic development.

Here, the authors develop generalized phased-array metasurface equations and design metasurface axicons and lenses to collimate and focus the spontaneous emission, respectively.
Nature Communications, Published online: 14 June 2021; doi:10.1038/s41467-021-23879-2 Longhua Shui Mi (LHSM) is a representative of the Chinese Cling peaches that have been central in global peach genetic improvement. Here, the authors assemble the genome of LHSM and show convergent selection for sweetness yet divergent selection for acidity in eastern vs. western cultivars through population gen
Antidepressiva läkemedel som SSRI-preparat tar oftast flera veckor på sig att börja verka. Men i en tidigare studie visade forskare att en ny sorts behandling där deltagare andades in lustgas, eller dikväveoxid, lindrade depressiva symtom redan efter ett par timmar.
Sheila Hunt, Patrick Russell, Michael Shipman and Bob Hely respond to Christian Wolmar's letter on his non-locked-down life Re Christian Wolmar's letter (8 June), at 84 my daily activity both during and after lockdown has been an hour's walk with my dog. I am able to enjoy this partly because of knee replacements 15 years ago and partly because of a walk around where I live that is accessible to
COVID-19 and antivaccine conspiracy theorists like Joe Mercola, Michael Yeadon, and Peter McCullough are spreading the conspiracy theory that COVID-19 vaccines are intended as a tool for "global depopulation". This is nothing more than an old antivaccine conspiracy theory repurposed for the pandemic. As ridiculous as it might seem, it is nonetheless very appealing to antivaxxers. The post first
Esa meddelar att de kommer att skicka iväg en ny rymdsond, Envision, om ungefär tio år. Uppdraget är att undersöka hur det kommer sig att Venus har utvecklats till att bli så olik jorden trots att de är ungefär lika stora och har en liknande sammansättning. Venus yta är dold bakom en ogenomskinlig atmosfär med tjocka moln av svavelsyra, och är fortfarande ganska outforskad.
Vem ska bevisa vad? Ibland kan man dras in i en diskussion med någon som påstår något spektakulärt eller rent av absurt. Det kanske kan vara att Bigfoot eller Loch … Continued Inlägget dök först upp på Vetenskap och Folkbildning .
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen provide better pain control and have fewer adverse effects than codeine, a commonly prescribed opioid, when prescribed after outpatient surgery, according to new research published in CMAJ (Canadian Medical Association Journal).
PLO's nye direktør er dr.jur. og vant til forhandlinger, politik og interessevaretagelse for slet ikke at tale om kolleger og samarbejdspartnere med tårnhøj faglighed. Nu mangler han blot at få opdateret sin viden om sundhedsvæsenet.
Graphics, game mechanics, character movements, and sound are all improving. But will we be playing games where it will feel and look like you are killing a real human being? The mindless muscle-memory focus of current FPS games saves the gameplay of any trauma that would come from shooting a human being in high-tense situations. As game-development programs and technology improve, we will reach a
I'm not sure if this gets asked often, so sorry if it does. I'm just having a hard time understanding this. I understand that identity is just your memories and Neurons and all that and that it's ever changing. But if I die, will I be really able to experience the copy of my consciousness? I have no way of knowing whether I am a clone of my original self at this moment, but my original clone is s
Fears two oil slicks would pollute eastern Corsica's holiday beaches eased Saturday after French officials prepared for the worst and naval boats armed with clean-up equipment arrived off the Mediterranean island.
