Elon Meets Anon Elon Musk has drawn the ire of a lot of people: crypto investors , union organizers , and "Saturday Night Live" cast members , just to name a few. However, it wasn't until Friday did he get called out by a fairly surprising group: the hacktivist organization Anonymous. The group released a video threatening the Tesla CEO for his alleged manipulation of cryptocurrency markets, acco
'Internationally significant' discovery of male with burial chains in Rutland is first of its kind His ankles secured with heavy, locked iron fetters, the enslaved man appears to have been thrown in a ditch – a final act of indignity in death. Now the discovery of the shackled male skeleton by workers in Rutland – thought to have been aged in his late 20s or early 30s – has been identified as rar
A new study claims networks of observers are responsible for determining physical reality. The scientists propose that observers generate the structures of time and space. The paper could help yield insights into the God Equation, which attempts to unify quantum mechanics and general relativity. Is there physical reality that is independent of us? Does objective reality exist at all? Or is the st
Last Tuesday, teams from Google and Harvard published an intricate map of every cell and connection in a cubic millimeter of the human brain. The mapped region encompasses the various layers and cell types of the cerebral cortex, a region of brain tissue associated with higher-level cognition, such as thinking, planning, and language. According to Google , it's the largest brain map at this level
The aurora borealis, or northern lights, that fill the sky in high-latitude regions have fascinated people for thousands of years. But how they're created, while theorized, had not been conclusively proven.
Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they're known for being tough, capable of surviving through drying, freezing, starvation, and low oxygen. Now, researchers reporting in the journal Current Biology on June 7 have found that not only can they withstand being frozen, but they can also persist for at least 24,000 years in the S

Edge of Space Just two weeks after officially stepping down as Amazon's CEO on July 5, Jeff Bezos is ready for a vacation to the edge of space. Next month, the second richest man in the world will be rocketing to space on board a New Shepard spacecraft built by his space tourism company Blue Origin , the billionaire announced on Instagram on Sunday. "Ever since I was five years old, I've dreamed
The classics department at Princeton University recently decided that the idea that classics majors ought to know Latin or Greek has been a mistake. Old-fashioned, perhaps. Until now, undergrads who wanted to major in the study of classical texts needed to come into the concentration with at least an intermediate level of Latin or Greek. But those students will no longer even have to learn either
Amazon founder's brother, Mark, and one other person will join Bezos onboard Blue Origin vessel on 20 July Jeff Bezos will no longer be the richest person on Earth on 20 July because the Amazon founder will be blasting off into space on the first crewed flight of his New Shepard rocket ship. Joining Bezos on the flight will be his younger brother, Mark, a former advertising executive and voluntee

Russian scientists find bdelloid rotifers deep in remote permafrost A microscopic worm-like creature, labelled an " evolutionary scandal " by biologists for having thrived for millions of years without having sex, has now been shown to persist for at least 24,000 years in Siberian permafrost and then reproduce, researchers have found. Multicellular invertebrates that are solely female, bdelloid r
On Friday, the US Food and Drug Administration (FDA) approved a new weight-loss drug for the first time since 2014. And that's a big deal: around 70 percent of adults in the US are either overweight or obese — meaning this treatment, if it holds up as an effective non-surgical approach to losing weight, could have significant public health implications. The drug, called semaglutide and made by Da
Just a few bacterial taxa found in ecosystems across the planet are responsible for more than half of carbon cycling in soils. These new findings, made by researchers at Northern Arizona University and published in Nature Communications this week, suggest that despite the diversity of microbial taxa found in wild soils gathered from four different ecosystems, only three to six groups of bacteria c

Last month, a group of University of Hong Kong academics gathered on the third floor of the campus's Jockey Club Tower for a highly anticipated town hall. Nearly a year had passed since Beijing imposed a new security law on Hong Kong, arresting dozens of people , reengineering the territory's voting system , and seizing the assets of a publicly listed company linked to activists. Staff members at
Michigan hop growers contend with unique challenges as a result of frequent rainfall and high humidity during the growing season. In 2018, growers approached Michigan State University researchers and the Michigan State University's Plant & Pest Diagnostics lab with concerns about a leaf blight they had never seen before. This was followed by reports of hop cones shattering during harvest and yield
Biomolecules regulate the biological functions inside every living cell. If scientists can understand the molecular mechanisms, then it is possible to detect severe dysfunction. At a molecular level, this can be achieved with fluorescent markers that are incorporated into the respective biomolecules. Researchers at the Universities of Göttingen and Edinburgh are now able to show that a complex of
To describe something as slow and boring we say it's "like watching grass grow", but scientists studying the early morning activity of plants have found they make a rapid start to their day—within minutes of dawn.
A research team demonstrates it is possible to predict individual preferences based on how a person's brain responses match up to others. This could potentially be used to provide individually tailored media content — and perhaps even to enlighten us about ourselves.
To investigate the role genes play in the evolution of social structure, researchers created an experiment they likened to the 1998 film 'The Truman Show.' Genetically identical versions of 20 fruit flies were placed in 98 controlled enclosures, and video cameras recorded their interactions. The study revealed the same clones occupied the same social positions in each enclosure, regardless of livi
The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to watch these reactions under real-world conditions, an advance that may help researchers find ways to make concrete more sustainable.
Many mainstream depictions of immigration at the southern border of the United States paint a dark picture, eliciting imagery of violent gang members and child trafficking. But how many undocumented immigrants are really involved in this kind of activity? Many people may be surprised to learn the answer is far fewer than they think.
As part of his Master's degree in civil engineering, an EPFL (Ecole Polytechnique Federale de Lausanne) student developed a connector for use in building sustainable structures.

About 60 percent of drugs on the market have hydrophobic molecules as their active ingredients. These drugs, which are not soluble in water, can be difficult to formulate into tablets because they need to be broken down into very small crystals in order to be absorbed by the human body.
Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their missions.
As individuals, we feel that we know what consciousness is because we experience it daily. It's that intimate sense of personal awareness we carry around with us, and the accompanying feeling of ownership and control over our thoughts, emotions and memories. But science has not yet reached a consensus on the nature of consciousness – which has important implications for our belief in free will an

Scientists at the Salk Institute are developing a promising approach for treating type 1 diabetes by using stem cells to create insulin-producing cells (called beta cells) that could replace nonfunctional pancreatic cells.
Bacteria found in brackish sediments can "eat" electricity and, in the process, absorb and lock away climate-warming carbon dioxide, research finds. Global oceans absorb about 25% of the carbon dioxide released into the atmosphere when fossil fuels are burned. Electricity-eating bacteria known as photoferrotrophs could provide a boost to this essential process, according to the study. This unusua
A new survey of roughly 900 American adults says that actually no, people don't want to live forever. When asked whether they'd like to take a pill that would allow them to live forever at their current age, only about 33 percent of survey respondents said yes, according to research published in the Journal of Aging Studies . Another 42 percent said no, while the remaining 25 percent wasn't sure.
This article was originally published on our sister site, Freethink. Nearly 2 million Americans suffer from type 1 diabetes — a condition that causes drastic spikes or drops in sugar levels and, in turn, dizziness, nausea, and fatigue. It's a condition that must constantly be monitored, something that a lot of diabetics find mentally exhausting. One diabetic, Naomi, told the BBC that she couldn't
A new study from researchers at Johns Hopkins Bloomberg School of Public Health and colleagues suggests a slowdown in the use of convalescent plasma to treat hospitalized COVID-19 patients led to a higher COVID-19 mortality during a critical period during this past winter's surge.

Researchers used protein mapping to show how abnormal levels of the neurotransmitter glutamate impair the functioning of neurons and oligodendrocytes. The findings could serve as a basis for more effective treatment.
A new study co-authored by University of Central Florida researchers shows that pre-Columbian people of a culturally diverse but not well-documented area of the Amazon in South America significantly altered their landscape thousands of years earlier than previously thought.
We sometimes think of the Amazon rainforest as unaltered by humans, a peek into the planet's past. In recent years, scientists have learned that many parts of the Amazon aren't untouched at all—they've been cultivated by Indigenous peoples for thousands of years, and mere centuries ago were the sites of cities and farmland. But that's not the case everywhere. In a new study in PNAS, researchers de
In an article scheduled to publish in PNAS, on June 7, 2021, a team of researchers led by Columbia University's Dustin R. Rubenstein, a Professor of Ecology, Evolution and Environmental Biology, found that within the same genus of marine snapping shrimp, Synalpheus, genome size and social behavior not only vary widely, but they are also co-evolving over time.
New research has revealed the genetic makeup of the earliest goat herds. The findings, assimilated from DNA taken from the remains of 32 goats that died some 10,000 years ago in the Zagros mountains, provide clues to how early agricultural practices shaped the evolution of these animals.
Every night during the spring and fall migration seasons, thousands of birds are killed when they crash into illuminated windows, disoriented by the light. But a new study in PNAS shows that darkening just half of a building's windows can make a big difference for birds. Using decades' worth of data and birds collected by Field Museum scientists at Chicago's McCormick Place convention center, the
Humanoid "Sophia" robot's face for reference AI robots of the future should not have physical faces. Physical faces on a head are permanent, cannot be replaced, have to have complex machinery, consume more power, and look creepy as all hell. Whereas a digital face on a screen can display the full range of human emotions, look realistic, easy to change/tweak, consume far less power. Here's an exam
Elon Musk and Jeff Bezos want to build cities on Mars. That's cool, but why ? Mars is some of the least desirable real estate you can think of, even if we did terraform it, we'd be left with a rock so far from earth that even our high speed communications would suffer enough lag to make normal conversation impossible. If it were my money, I'd bet it on building orbital space colonies. Tomorrow's
A new rapid blood test could confirm if a person has received a COVID-19 vaccine while they wait to board a plane or enter a sporting event. One challenge as society reopens is identifying who has been vaccinated for SARS-CoV-2, the virus that causes COVID-19. The new COVID-19 antibody test is similar to one used at home to determine blood type, where the user pricks a finger and places a drop of
Chris McGrath, a photographer with Getty Images, recently spent time in Turkey's Konya province, where extreme drought conditions have been taking a heavy toll on farmers and the land. For farmers, the lack of rain gives them little option but to tap into the groundwater supplies to sustain their crops, forcing some to turn to installing illegal ground wells. However, the reliance on groundwater
Vaccines are critical tools for fighting COVID-19, and new vaccines will expand overall vaccine availability.

By reviewing the essay, an historian of nursing at the University of Pennsylvania School of Nursing (Penn Nursing) extends that construct to include nurses and patients, delivering a local and personal meaning to the epidemic experience.
Current guidelines recommend stopping cervical cancer screening at age 65, but women over age 65 make up over one in five new cervical cancer diagnoses, and are twice as likely to die after a cervical cancer diagnosis compared to younger women. New research from Boston Medical Center found that fewer than one in three women aged 64 to 66 met the criteria to discontinue cervical cancer screening wh
How people consume news and take actions based on what they read, hear, or see, is different than how human brains process other types of information on a daily basis, according to new research. While the current state of the newspaper industry is in flux, the researchers discovered people still love reading newspapers. The researchers believe a newspaper's physical layout and structure could hel
AI Matchmaker A new brain-computer interface system, trained to pick up on the neural activity of your brain when it sees a new person's face, is sophisticated enough to predict who you will and won't be attracted to. And by matching your neural patterns to existing data of other participants who already ran the gauntlet of headshots, the algorithm can supposedly predict whether users will find s
It's hard to see more than a handful of stars from Princeton University, because the lights from New York City, Princeton and Philadelphia prevent our sky from ever getting pitch black, but stargazers who get into more rural areas can see hundreds of naked-eye stars—and a few smudgy objects, too.
Peer rejection and social network isolation aren't the same thing in early adolescence, according to new research. For years, psychology researchers have treated peer rejection and social network isolation as being somewhat interchangeable when it comes to early adolescence; it was thought that if kids fell into one of those two groups, they fell into the other. The new research finds that social
In young women, Staphylococcus saprophyticus is a main cause of urinary tract infections (UTI), reaching 20% prevalence. Understanding the epidemiology of this microorganism can help identify its origin, distribution, causes, and risk factors. Now, ITQB NOVA researchers led by Maria Miragaia showed evidence that Staphylococcus saprophyticus can originate in food, namely in the meat-production chai
A new study at the University of Chicago has determined that restoring a single microbial species — Bacteroides sp. CL1-UC (Bc) — to the gut microbiome at a key developmental timepoint can prevent antibiotic-induced colitis in a mouse model of the condition.
An international team of scientists led from the Centre for Astrobiology (CAB, CSIC-INTA), with participation from the Instituto de Astrofísica de Canarias (IAC), has used the Gran Telescopio Canarias (GTC) to study a representative sample of galaxies, both disc and spheroidal, in a deep sky zone in the constellation of the Great Bear to characterize the properties of the stellar populations of ga
Many contemporary political conflicts are between those who would prioritize the needs of local or national communities and those with a more universal outlook. According to a new study by IASS researcher Silvia Weko, this split between 'communitarian' and "cosmopolitan" Europeans is also evident in their attitudes towards European climate policy. Achieving climate neutrality without exacerbating
Researchers have identified more than 1,700 large sources of methane in an oil field that spans Texas and New Mexico, with about half of them likely being malfunctioning equipment. If even just the most persistent leaks—123 of these sources—were repaired, emissions of the potent greenhouse gas could drop by 55 tons an hour, the researchers say. That's 5.5% of all methane emissions from oil and ga

The measurement postulate is crucial to quantum mechanics. If we measure a quantum system, we can only get one of the eigenvalues of the measured observable, such as position, energy and so on, with a probability. Immediately after the measurement, the system will collapse into the corresponding eigenstate instantly, known as state collapse. It is argued that the non-cloning theorem is actually a
In football, chance is defined as actions or situations occurring during the game that cannot be planned and are therefore difficult to train for. Take for instance deflected shots, balls that rebound off the post only to be kicked straight into the goal or goals that are unintentionally assisted by a defender. The primary focus of most researchers has been on analyzing success factors, to enable
