The tactics police are using to prevent bystander video
Kian Kelley-Chung was wearing a black T-shirt with the logo of his documentary and art collective on the day last summer when he found himself filming the Washington, DC, police during a protest. It was August 13, 2020, and Kelley-Chung had been recording Black Lives Matter demonstrations in the city for a couple of months. At this one, in the Adams Morgan neighborhood, he saw an officer push som
NASA's Mars Helicopter Fails to Make It Off the Ground for Fourth Flight
Grounded NASA's Mars helicopter has hit a bit of a snag. "Aim high, and fly, fly again," a Thursday tweet by NASA's Jet Propulsion Laboratory reads. "The Mars Helicopter's ambitious fourth flight didn't get off the ground, but the team is assessing the data and will aim to try again soon." In reality, it remains unclear what the helicopter's current state is — and it would be a shame if it had al
Space Force Chief Scientist: "Human Augmentation" Is Now Necessary
BrainPal The head scientist of the US Space Force has an unusual idea for how to maintain military dominance: augmenting and upgrading human soldiers. Speaking at an Air Force Research Laboratory event, Space Force chief scientist Joel Mozer suggested that we're entering an era during which soldiers can become a "superhuman workforce," according to Metro , thanks to new tech including augmented a
The Hot-Person Vaccine
I hope we can all agree that "vaccine culture" is a bit depressing. The idea of wearing an evening gown to a COVID-19-vaccine appointment is objectively sad, and speaking from personal experience, taking an hour-long bus ride to a CVS at the dead center of Staten Island, New York, for medical treatment is not fun or exciting except by dramatic contrast to events prior. And when vaccine culture is

Joe Rogan Explains Anti-Vax Comments: "I'm Not a Doctor, I'm a F*cking Moron"
It's a hard bar to clear, but former "Fear Factor" host and current podcaster Joe Rogan seems to have made his worst — or at least most widely criticized —take yet. And now he's backing down, sort of. The vaccines currently approved for use in the United States have done tremendous work protecting people from the coronavirus. New COVID-19 infections, hospitalizations, and deaths have declined con
Figures on Covid deaths post-jab show vaccine's success, scientists say
Small number have died after being vaccinated, mostly having caught virus before dose could take effect A small number of people vaccinated against Covid have been admitted to hospital with the disease and died, researchers have found, but most were frail and elderly and caught the virus before the jab could take effect. Scientists say their findings are reassuring. They bear out the conclusions
Why the Filibuster Suits the GOP Just Fine
In the Senate today, a simple majority isn't enough to pass a bill: 60 out of 100 votes are necessary to break a so-called filibuster by invoking "cloture" to end debate. Routine use of the filibuster is a modern and accelerating phenomenon. Democratic Senator Joe Manchin of West Virginia, who regards the filibuster as a permanent fixture worthy of protection, has seen the cloture rule invoked 1,
FAA Authorizes Launch of Next Three Starship Prototypes
The Federal Aviation Administration has authorized three upcoming launches of SpaceX's Starship spacecraft, according to a recent statement .

The Unspoken Wedge Between Parents and Grandparents
Martin parr / Magnum photos One of the sweetest parts of being a grandparent is being invited by your own adult children to spend time with your grandkids. But the invitation comes with a few conditions, and in even the most loving families, grandparents ignore these rules on a regular basis. For many reasons, they can't help overstepping the boundaries, whether because of a prickliness at their
Move over CRISPR, the retrons are coming
While the CRISPR-Cas9 gene editing system has become the poster child for innovation in synthetic biology, it has some major limitations. CRISPR-Cas9 can be programmed to find and cut specific pieces of DNA, but editing the DNA to create desired mutations requires tricking the cell into using a new piece of DNA to repair the break. This bait-and-switch can be complicated to orchestrate, and can ev

Organic Electrochemical Synaptic Transistor
The title of this post should be provocative, if you think about it for a minute. For "organic" read flexible, soft, and biocompatible. An electrochemical synapse is essentially how mammalian brains work. So far we can be talking about a biological brain, but the last word, "transistor", implies we are talking about a computer. This technology may represent the next step in artificial intelligenc

The birth of childhood: A brief history of the European child
It took several thousand years for our culture to realize that a child is not an object. Learning how to treat children as humans continues to this day. "Nature wants children to be children before they are men," wrote Jean-Jacques Rousseau in the book Emile, or On Education (1762). While Rousseau did not see children as humans, he appealed to parents to look after their offspring. "If we conside
Fish have been swallowing microplastics since the 1950s
Forget diamonds—plastic is forever. It takes decades, or even centuries, for plastic to break down, and nearly every piece of plastic ever made still exists in some form today. We've known for a while that big pieces of plastic can harm wildlife—think of seabirds stuck in plastic six-pack rings—but in more recent years, scientists have discovered microscopic bits of plastic in the water, soil, and

Studying top quarks at high and not-so-high energies
CERN's Large Hadron Collider (LHC) is famous for colliding protons at world-record energies—but sometimes it pays to dial down the energy and see what happens under less extreme conditions. The LHC started operation in 2010 with a collision energy of 7 TeV, and ran at 13 TeV from 2015 to 2018. But for one week in 2017, the LHC produced moderate-intensity collisions at only 5 TeV—allowing scientist
'Awake' concept brings proton bunches into sync
The future of particle acceleration has begun. Awake is a promising concept for a completely new method with which particles can be accelerated even over short distances. The basis for this is a plasma wave that accelerates electrons and thus brings them to high energies. A team led by the Max Planck Institute for Physics now reports a breakthrough in this context. For the first time, they were ab
Newly discovered Miocene biome sheds light on rainforest evolution

Rice-sized baby mantis shrimp throw a powerful punch
Even when they are smaller than a short grain of rice, larvae of the Philippine mantis shrimp display ultra-fast movements, according to a new study. Their ultra-fast punching appendages measure less than 1 millimeter (0.039 inches), and develop right when the larva exhausts its yolk reserves, moves away from its nest, and out into the big wide sea. It immediately begins preying on organisms smal
Software Bug Delays Ingenuity Helicopter's 4th Mars Flight
NASA's Ingenuity helicopter was supposed to complete its fourth flight early yesterday, but data beamed back to Earth indicates that did not happen . NASA isn't worried, though. This appears to be the same issue that caused the delay in Ingenuity's first flight timeline. NASA says it's planning to try this one again today, and we should know in a few hours whether or not it was successful. Becaus

Icy clouds on ancient Mars may have given rise to lakes and rivers
In a recent study, researchers created a computer model to explore how varying levels of surface ice would have affected clouds above the Martian surface. The results showed that icy, high-altitude clouds would have formed if Mars was covered in relatively small amounts of ice. These clouds would have helped warm the planet. NASA's Perseverance rover may soon confirm this hypothesis by taking geo
Holographic histopathology enables fast, precise diagnostics
Histology is the study of biological tissues at a microscopic level. Also called microscopic anatomy, histology is widely used to provide diagnosis of cancer and other diseases. For example, tissue samples obtained during surgery might help to determine whether further surgical action is needed, and further surgery may be avoided if a diagnosis can be rapidly obtained during an operation.

Almost ev
Tropical lakes may emit more methane
Methane is not the most abundant greenhouse gas in our atmosphere, but it is among the most potent. Roughly a quarter of global methane emissions come from natural sources, and freshwater ecosystems are the largest source of atmospheric methane. Most of the data on methane dynamics in aquatic ecosystems come from boreal and temperate environments. Less is known about the fate of methane in tropica
Electron beam melting gets brittle metal into shape
Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high-temperature furnaces, or the fusion reactor. However, the metal is highly brittle and, hence, difficult to process. Researchers of Karlsruhe Institute of Technology (KIT) have developed an innovative approach
Researchers analyze circulating currents inside gold nanoparticles
According to classical electromagnetism, a charged particle moving in an external magnetic field experiences a force that makes the particle's path circular. This basic law of physics are exploited in designing cyclotrons that work as particle accelerators. When nanometer-size metal particles are placed in a magnetic field, the field induces a circulating electron current inside the particle. The
Glacier avalanches more common than thought
One tends to think of mountain glaciers as slow moving, their gradual passage down a mountainside visible only through a long series of satellite imagery or years of time-lapse photography. However, new research shows that glacier flow can be much more dramatic, ranging from about 10 meters a day to speeds that are more like that of avalanches, with obvious potential dire consequences for those li
Structural changes in snap-frozen proteins
Researchers have succeeded in ultra-fast freezing proteins after a precisely defined period of time. They were able to follow structural changes on the microsecond time scale and with sub-nanometer precision. Owing to its high spatial and temporal resolution, the method allows tracking rapid structural changes in enzymes and nucleic acids.

Renewable energy is having its moment in the sun . And in the wind . And, lesser known but equally relevant, in the water. Tidal turbines don't get as much buzz as solar and wind farms, and there are less of them out there, but the number is growing—and a unique new one is about to go live. A Scottish company called Orbital Marine Power built what it's calling the "most powerful tidal turbine in
Get to know your plants through ionomics
Living beings need elements to develop properly. The study of ionomics measures and analyzes the element accumulations in living organisms to determine which mineral nutrients are required and not required for growth. Associate Professor Toshihiro Watanabe from Hokkaido University's Research Faculty of Agriculture applies this approach to learn about mineral accumulation in both plants and soil, i
Rate of Glacial Melting Is Accelerating, Comprehensive Study Finds
Credit: Luca Galuzzi/CC BY-SA 2.5 For scientists who study climate change, it's no longer a question of whether or not human activity is affecting the planet. It's a question of how much we're wrecking the only place we call home. According to a new study from a French-led team, things aren't going great. The researchers found that the rate of ice loss from glaciers has accelerated for the first
Important factor in the development of dendritic cells identified
Dendritic cells are divided into Type 1 (DC1) and Type 2 (DC2) dendritic cells. Each type fulfils different functions: DC1 provide an immune response to bacteria and viruses, DC2 protect against fungal or parasitic infections. In a recent study conducted at MedUni Vienna's Institute of Cancer Research, researchers found that a particular group of proteins plays a major role in the development of T
Navigating the squircle
Successful navigation requires the ability to separate memories in a context-dependent manner. For example, to find lost keys, one must first remember whether the keys were left in the kitchen or the office. How does the human brain retrieve the contextual memories that drive behavior? J.B. Julian of the Princeton Neuroscience Institute at Princeton University, USA, and Christian F. Doeller of the
Analyzing COVID-19's effect on the clothing industry
While COVID-19 hit the textile and apparel industry especially hard, businesses with a strong online presence, several manufacturing locations and an ability to quickly adjust their merchandise were better able to withstand the pandemic's impact, according to a new study from the University of Missouri.
One incredible ocean crossing may have made human evolution possible
Humans evolved in Africa, along with chimpanzees, gorillas and monkeys. But primates themselves appear to have evolved elsewhere—likely in Asia—before colonizing Africa. At the time, around 50 million years ago, Africa was an island isolated from the rest of the world by ocean—so how did primates get there?
Having an epidural doesn't boost autism risk
Having an epidural during childbirth is not associated with does not increase the risk for autism in children, according to a new study. The findings help resolve questions raised by an earlier, widely criticized report on the topic. "We did not find evidence for any genuine link between having an epidural and putting your baby at increased risk of autism spectrum disorder," says senior author Al
Not two different worlds: QAnon and the offline dangers of online speech
The new docuseries, Q: Into the Storm, is an investigation into the QAnon conspiracy theory and the shadowy online subcultures and spaces that fuel it. An important narrative throughout the series is the negative consequences of online speech, which demonstrates the danger of digital dualism: the tendency to treat online life as distinct, separate and sometimes as less real from offline life.
Fix for asbestos in soil may risk nearby water
The current method for handling Superfund sites containing asbestos may actually increase the likelihood of human exposure to the cancer-causing material. Currently, the Environmental Protection Agency (EPA) largely remedies sites with asbestos by capping them with soil to lock the buried toxin in place. "People have this idea that asbestos is all covered up and taken care of," says Jane Willenbr
Will the end of the COVID-19 pandemic usher in a second Roaring '20s?
While some places remain mired in the third wave of the pandemic, others are taking their first tentative steps towards normality. Since April 21, Denmark has allowed indoor service at restaurants and cafes, and football fans are returning to the stands. In countries that have forged ahead with the rollout of vaccines, there is a palpable sense of optimism.
How small-scale seafood supply chains adapt to COVID-19 disruptions
In February 2020, Rio (not his real name), a crab and sea snail processor in Langkat regency on the Indonesian island of Sumatra, found his business drying up. Normally at this time of year his business would have been booming from seafood exports to China and Hong Kong for the Lunar New Year festival.
Spatial methods for identifying unusual accumulations at Paleolithic sites
A collaboration between researchers at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) and the Human Evolution Research Center (HERC) of the University of California at Berkeley has allowed a study to be published in the Journal of Archaeological Method and Theory, which reviews the traditional and more innovative methods for identifying unusual horizontal concentrations of
The foundations of mathematics are unproven
In 1900, mathematician David Hilbert laid down 23 problems for the mathematics world to solve, the biggest of which was how to prove mathematics itself. Far from solving the issue, Kurt Gödel showed just how groundless the axioms of mathematics are. Gödel's theorem does not devalue mathematics but reveals that some truths are unprovable. Everything's a bit crazy at the moment. We're drowning in a
My belly is angry, my throat is in love: Body parts and emotions in Indigenous languages
Many languages in the world allude to body parts to describe emotions and feelings, as in "broken-heart," for instance. While some have just a few expressions like this, Australian Indigenous languages tend use a lot of them, covering many parts of the body: from "flowing belly" for "feel good" to "burning throat" for "be angry" to "staggering liver" meaning "to mourn."

Lönen var vanligaste orsaken till strejk
I år är det 100 år sedan som det elektriska stamnätet byggdes ut i Sverige. Med det följde det som kallas den andra industriella revolutionen och en förändrad arbetsmarknad. Jordbrukssektorn minskade samtidigt som industrin och mer kvalificerad tjänstesektor tog ett språng. Under samma period tog strejkerna på svensk arbetsmarknad fart – under bara år 1919 bröt 440 strejker och lockouter ut.
Paper partly funded by controversial stem cell company retracted
The timestamps always get you in the end. A widely touted 2017 paper linked to a controversial company promoting regenerative medicine has been retracted after the journal came to doubt the validity of the data thanks to some strange anachronisms and a digital breadcrumb. "Intra-articular injection in the knee of adipose derived stromal cells (stromal … Continue reading

Care teams differ for black, white surgical patients in the same hospitals
A new study finds black patients are more likely to die after their heart bypass surgery if they're at a hospital where some care teams see mostly white patients and others see mostly black patients. On the other hand, mortality rates are comparable between black and white patients after heart bypass surgery when the teams of health care providers at their hospitals all care for patients of all ra
Det genetiska alfabetet
Som en stor del av allmänheten numera känner till, innehåller DNA fyra olika slags nukleobaser, nämligen adenin, cytosin, guanin och tymin (betecknade A, C, G och T). RNA innehåller uracil (U) i stället för tymin. Man trodde länge att dessa var de enda «bokstäverna» i den genetiska informationen hos alla organismer och virus. Emellertid fann man redan 1977 ett virus som angriper cyanobakterier, so
Inga ärvda dna-skador hos barn efter Tjernobyl
Det har gått 35 år sedan reaktor fyra i kärnkraftverket i Tjernobyl i dåvarande Sovjetunionen havererade och stora mängder radioaktivt material i form av partiklar och joniserande strålning spreds. Initialt avled 30 personer och 134 drabbades av strålsjuka, varav 11 avled i sviterna under de följande tio åren. Frågan var om även nästa generation skulle drabbas av skador som ett resultat av att dna
Cultured Meat will be the Most Impactful Technology of the next Several Decades

Pain From Your Second Brain
Most people can agree they've experienced stomachaches that have made them cancel plans or put off work because the pain overrides motivation to interact with others or focus on simple tasks. The ability of our stomach to influence our thoughts and feelings has given rise to the idea of the gut being our second brain". This second brain, or the enteric nervous system (ENS), is a collection of ner

Structure and activity of SLAC1 channels for stomatal signaling in leaves [Biochemistry]
Stomata in leaves regulate gas exchange between the plant and its atmosphere. Various environmental stimuli elicit abscisic acid (ABA); ABA leads to phosphoactivation of slow anion channel 1 (SLAC1); SLAC1 activity reduces turgor pressure in aperture-defining guard cells; and stomatal closure ensues. We used electrophysiology for functional characterizations of Arabidopsis…
Digital mental health interventions for young people are perceived promising, but are they effective

Exoskeleton could one day boost walking speed of older adults
A new ankle exoskeleton allowed users to walk, on average, 42% faster than when they wore normal shoes and no exoskeleton, researchers report. Being unable to walk quickly can be frustrating and problematic, but it is a common issue, especially as people age. Noting the pervasiveness of slower-than-desired walking, engineers tested how well a prototype exoskeleton system—which attaches around the
Processed food might boost risk for chronic infection diseases
Processed diets, which are low in fiber, may initially reduce the incidence of foodborne infectious diseases such as E. coli infections , but might also increase the incidence of diseases characterized by low-grade chronic infection and inflammation such as diabetes, a study with mice shows. Researchers investigated how changing from a grain-based diet to a highly processed, high-fat Western-styl
