Archaeological discoveries are shattering scholars' long-held beliefs about how the earliest humans organised their societies – and hint at possibilities for our own In some ways, accounts of "human origins" play a similar role for us today as myth did for ancient Greeks or Polynesians. This is not to cast aspersions on the scientific rigour or value of these accounts. It is simply to observe tha
Vienna OnlyFans Who says you can't get a little classy on OnlyFans? The Vienna Tourist Board is turning to the content subscription platform to post images of artwork deemed too NSFW for Facebook, Instagram, and TikTok, according to a fascinating new story by NBC .

Governor Greg Abbott is afraid. Not of COVID-19, which is killing thousands of Texans, but of losing his primary. Last week, Abbott announced that he was banning COVID-vaccine mandates by "any entity" in Texas, a policy so absurd that you'd be forgiven for thinking, as the running joke on social media goes, that the coronavirus wrote the executive order itself. You might as well ban restaurants f
Thanks to two microphones aboard NASA's Perseverance rover, the mission has recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel, and motors whirring as the spacecraft moves its arm. These sounds allow scientists and engineers to experience the Red Planet in new ways—and everyone is invited to listen in.

Ever since I entered what can generously be called my "mid-30s," doctors have asked about my pregnancy plans at every appointment. Because I'm career-minded and generally indecisive, I've always had a way of punting on this question, both in the doctor's office and elsewhere. Well, we can always adopt , I'll think, or say out loud to my similarly childless and wishy-washy friends . Adoption, afte
Bad Bill Bill Gates has spent the years since retiring from Microsoft cultivating an image as a lovable, philanthropic nerd.

Listen and subscribe: Apple Podcasts | Spotify | Stitcher | Google In the social-media age , we curate images of our lives on a screen—making it especially easy to translate images of perfection as the image of oneself. But the pressure to pretend we are perfect is exactly the thing holding us back from experiencing the happiness we seek—and limiting our ability to be our whole, authentic selves.
Understanding how proteins bend, twist, and shape-shift as they go about their work in cells is enormously important for understanding normal biology and diseases. But a deep understanding of protein dynamics has generally been elusive due to the lack of good imaging methods of proteins at work. Now, for the first time, scientists at the UNC School of Medicine have invented a method that could ena

The value of UK agriculture could be boosted by millions of pounds a year if thousands of honeybee hives were deployed on solar parks across the country, a new study reveals. However, scientists caution that the benefits of managing solar parks for wild pollinators over honeybees should be prioritized where appropriate and should be assessed on a site by site basis.
How much will solar power really cost in China in the coming decades, including the challenges its inherent variability poses to the grid? Researchers have found that solar energy could provide 43.2% of China's electricity demands in 2060 at less than two-and-a-half U.S. cents per kilowatt-hour.
In Star Trek, characters carry a little handheld device called a tricorder that they can point at objects to analyze and identify them. When the show's writers cooked up the idea in the 1960s, it was purely science fiction, but a new paper in New Phytologist takes the idea a step closer to reality. The researchers used a handheld device that looks a little like a ray gun to record how plant leaves

Nitrous oxide (N2O) is a potent greenhouse gas, with 300 times the warming ability of carbon dioxide. Due to fertilizer runoff from farm fields, an increasing load of nitrogen is washing into rivers and streams, where nitrogen-breathing microbes break some of the fertilizer down into N2O, which the river releases into the atmosphere as it tumbles toward the ocean. But, until now, scientists haven'
A large genome-wide association study in East Asians uncovers novel genetic links to depression, calling attention to the consequences of underrepresentation of non-European groups in genetic research data.
Does anyone know what exactly would need to be done in order to make wireless power transfer work over long distances or what is the barrier stopping it from doing so? Maybe it's the way electricity flows through the air and/or the fact that it would fry many of the things that get in its way. But perhaps it is just something to do with the machines. I do not know. Is it even physically possible?
A high-fat diet (HFD) can induce hyperglycemia and metabolic syndromes that, in turn, can trigger visual impairment.

Along with the use of face masks, social distancing in public remains one of the most practiced front-line defenses against the spread of COVID-19. However, flows of pedestrians, including those practicing the 6-foot rule for distancing, are dynamic and characterized by nuances not always carefully considered in the context of everyday, public spaces.
In many parts of the world, the supply of COVID-19 vaccines continues to lag behind the demand. While most vaccines are designed as a two-dose regimen, some countries, like Canada, have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose.
The COVID-19 pandemic has led to more than 218 million infections and over 4.5 million deaths as of Sept. 3, 2021. Nonpharmaceutical interventions (NPIs), such as case isolation, quarantining contacts, and the complete lockdown of entire countries, were implemented in an effort to contain the pandemic. But these NPIs often come at the expense of economic disruption, harm to social and mental well-

A clinical trial has found that treatment with the immunomodulator interferon beta-1a plus the antiviral remdesivir was not superior to treatment with remdesivir alone in hospitalized adults with COVID-19 pneumonia. In addition, in a subgroup of patients who required high-flow oxygen, investigators found that interferon beta-1a was associated with more adverse events and worse outcomes.
A study identified 514 marine species in the bathing areas of the Barcelona Forum, an artificial beach affected by different anthropogenic impacts. This high biodiversity—which includes the presence of exotic species—is a shocking finding in such an altered marine habitat like this city beach in Barcelona (Catalonia, Spain).
Recently, photoredox catalysis has emerged as an appealing coupling partner for transition metal catalysis, termed metallaphotocatalysis, to develop new synthetic methodologies as well as improve the efficiency of established transformations. Conversely, most of these dual catalytic platforms have focused on the use of homogeneous photoredox catalysts such as Ru- and Ir-based polypyridyl complexes
This research is led by Prof. Yunqi Liu (Institute of Chemistry Chinese Academy of Sciences) and Prof. Yunlong Guo (Institute of Chemistry Chinese Academy of Sciences). Ambipolar polymer semiconductors have wide applications in electronic devices such as organic field-effect transistors (OFETs), logic circuits, and organic light-emitting transistors (OLETs). Although some high-performance ambipola
For all its supposed genetic editing finesse, CRISPR's a brute. The Swiss Army knife of gene editing tools chops up DNA strands to insert genetic changes. What's called "editing" is actually genetic vandalism —pick a malfunctioning gene, chop it up, and wait for the cell to patch and repair the rest. It's a hasty, clunky process, prone to errors and other unintended and unpredictable effects. Bac

Our children are growing up in a volatile climate. It's already damaging their health, wealth and well-being. Universities can be leaders in helping young people gain the knowledge they need to navigate this uncertain future. Curious Climate Schools, a project that connects young people directly with experts who can answer their climate questions, is a model for just this kind of leadership.
To achieve sustained recovery from the COVID-19 pandemic and avoid an "impending health catastrophe," countries must commit to targeted action on climate change, health experts have urged ahead of the UN climate summit, COP26.
Planar perovskite light-emitting diodes (LEDs) are high-performance and cost-effective electroluminescence devices that are ideal for large-area display and lighting applications. By exploring the emission layers with high ratios of horizontal transition dipole moments (TDMs), researchers can boost the photon outcoupling of planar LEDs. The LEDs that are based on anisotropic perovskite are ineffic
Plants know winter is coming. But exactly how they detect this change in seasons has never been clear. Researchers took a new approach to uncover this plant secret: They asked one. The answer they received—in the form of changes in the gene expression of a common weed known as Arabidopsis —has implications for farmers and conservationists alike as climate change increasingly makes native ecosyste

The wide availability of drones has changed everything, including making throwing a grenade a thing of the past . Fortunately, most of us will put them to more peaceful uses, like filming our lives, something the Black YLR/C S32T HD 4K Single-Camera Drone excels at. It's on sale for just $99.95 (reg. $410). Flying With Ease First of all, it's built with newcomers in mind. It's easy to control, wi
People with unpaid health care bills are less likely to seek needed medical care, evidence indicates. Earlier this summer, Stanford economist Neale Mahoney sounded an alarm with a study he coauthored: Americans have at least $140 billion in unpaid health care bills sitting in collection agencies—making the country's medical debt crisis far bigger than anyone had realized. Based on an analysis of
In a collaboration between the University's Center on the Dynamics of Ethnicity (CoDE) and The Runnymede Trust, a new briefing has highlighted how the pandemic has impacted the UK's ethnically diverse high streets.
One way that scientists monitor climate change is through the measure of sea ice extent. Sea ice extent is the area of ice that covers the Arctic Ocean at a given time. Sea ice plays an important role in reflecting sunlight back into space, regulating ocean and air temperature, circulating ocean water, and maintaining animal habitats.
Next month the UN will host the 26th conference on climate change, the COP26 . At this point the discussion is not so much what the goal should be, it's how to achieve that goal. The Paris Accords set that goal at limiting global warming to 1.5 C above pre-industrial levels. In order to achieve this outcome goal the consensus is that we need to achieve the primary goal of net zero green house gas
On 22 September, around midday, ESA's Integral spacecraft went into emergency Safe Mode. One of the spacecraft's three active 'reaction wheels' had turned off without warning and stopped spinning, causing a ripple effect that meant the satellite itself began to rotate.
Kenyan world record holder Agnes Tirop was found stabbed to death at her home in the western town of Iten last week.

Arguably, no mode of writing has influenced the past decade of novels more than autofiction, a catchall term for books that call themselves fiction while claiming to be rooted, in some way, in their authors' real lives. Amid this boom, critics and readers alike have shown a certain anxiety over how based in fact a novel can be—and how anyone might know, given that no autofiction writer purports t
The Lancet has retracted a decade-old case report by a group from Japan after concluding that the authors misrepresented the originality of the work.

Grotesque little creatures with armor-like horns, misshapen torsos and some with spikes protruding from their sides are lurking in the waters of the Gulf of Mexico. They appear in an array of oranges and blues, though several are see-through. Some appear part alien and part Hunchback of Notre Dame. They are the visions of which nightmares are made. But to marine scientist Heather Bracken-Grissom,
While West Virginia's Senator Joe Manchin is doing his best to block climate policy and save his state's dying fossil fuel industry, there is no reason to believe that the proposed "Clean Electricity Program" policy design is the only way to accelerate decarbonization. The problem for many utilities is the capital cost of the infrastructure for decarbonization. The infrastructure and Build Back Be
The Bitcoin bulls are racing again. A year ago the cryptocurrency was valued at less than US$12,000. Now it has passed the symbolic milestone of US$60,000, nudging the US$63,255 record it reached in mid-April, before its price fell to as low as US$30,000 in July.

Meningitis is a very serious brain infection with limited treatment options. In a new study performed in rats, researchers present an alternative treatment based on immune cells that helps rinse away toxins that accumulate during the infection.
I think it does the opposite. Simply cause as a kid and teenager, I was the worst kind of daydreamer, all I did all day was visualize and get lost in visuals. And my day to day cognitive function was diabolical. I was simply "away with the fairies", "out of touch", "not tuned in", and as a result, cognitively demanding tasks that required attention and focus was something I often made a mess of.
Researchers have identified a chemical compound that may be suitable as an active agent against several different unicellular parasites. Among these are the pathogens that cause malaria and toxoplasmosis. The point of attack for this promising substance is the protein tubulin: It helps cells divide and therefore is essential for the multiplication of the parasites.
A new study has uncovered neuronal circuitry in the brain of rodents that may play an important role in mediating pain-induced anhedonia — a decrease in motivation to perform reward-driven behaviors. Researchers were able to change the activity of this circuit and restore levels of motivation in a pre-clinical model of pain tested in rodents.
