Why science can't resist the allure of Venus: new missions to Earth's nearest planetary neighbour
With a surface hot enough to melt lead, Venus has been left alone by space agencies for a decade. Now we are about to learn more about its climate – and the chances of life on other planets A fleet of robot spaceships is to descend on Venus in a few years and begin probing the most inhospitable world in the solar system. One craft will drop through the planet's crushingly dense – and searingly ho

Elon Musk Joins Call to Free Britney Spears
Free Britney Tesla CEO Elon Musk took to Twitter in the early hours of Monday morning to voice his support for pop icon Britney Spears in the wake of her tragic testimony regarding her conservatorship and abuse at the hands of her father . "Free Britney," Musk said in a refreshingly considerate tweet . Free Britney — Elon Musk (@elonmusk) July 5, 2021 The SpaceX founder might have been at least s
The City of David and the sharks' teeth mystery
Scientists have found an unexplained cache of fossilized shark teeth in an area where there should be none—in a 2900 year old site in the City of David in Jerusalem. This is at least 80 km from where these fossils would be expected to be found. There is no conclusive proof of why the cache was assembled, but it may be that the 80 million-year-old teeth were part of a collection, dating from just a
Building a better biosensor polymer
A new organic (carbon-based) semiconducting material has been developed that outperforms existing options for building the next generation of biosensors. An international research team led by KAUST is the first to overcome some critical challenges in developing this polymer.
What went so wrong with covid in India? Everything.
On April 21, Ashley Delaney brought his father-in-law to the Goa Medical College and Hospital, the largest public hospital in the small southwestern Indian state. The hospital was in chaos and the wards were packed, with all 708 covid beds occupied—so 69-year-old Joseph Paul Alvares, a cancer survivor, had to lie on a gurney for nearly three days for a bed to become available. The bathrooms were
Constructed wetlands are best protection for agricultural runoff into waterways
A new paper from a lead author based at the University of Kansas finds wetlands constructed along waterways are the most cost-effective way to reduce nitrate and sediment loads in large streams and rivers. Rather than focusing on individual farms, the research suggests conservation efforts using wetlands should be implemented at the watershed scale.
Even Trigger Warning Is Now Off Limits
Thirty years ago, someone taught me to say actor rather than actress and chairperson rather than chairman , to discourage our thinking of occupational performance as elementally distinct depending on sex. I understood. Language does not shape thought as much as is often supposed. But words can nudge concepts in certain directions if the connection between the word and the concept is clear enough;
Why I'm glad that I'm an 'overthinker'
Examining every aspect of a question can be exhausting, but the most amazing insights can be gained that way The first time I remember someone telling me not to overthink was when I was trying to suss out breastfeeding. "Don't overthink it," said my friend, "just go with it." "Just going with it" is not something I do. I have to really understand what I'm doing and then I think through almost eve
The Pandemic Did Not Affect Mental Health the Way You Think
You've probably heard that the coronavirus pandemic triggered a worldwide mental-health crisis. This narrative took hold almost as quickly as the virus itself. In the spring of 2020, article after article —even an op-ed by one of us—warned of a looming psychological epidemic. As clinical scientists and research psychologists have pointed out , the coronavirus pandemic has created many conditions

The Other July 4
When my wife and I were young parents living in Manhattan, we rented an apartment above a psychiatrist with many wealthy patients. Through each hour of the working day, a succession of limousines and drivers would wait on the curb for one patient after another to exit the office. I once had the opportunity to ask what brought his clients to his door. He answered that they all presented versions o
Shall we vaccinate our children? We could start by asking them first | Russell Viner
If under-18s are vulnerable, let's jab straight away. Then we need a wider plan that doesn't leave teenagers as the unvaccinated 'class apart' The UK vaccination programme has been an extraordinary success. However, as most adults become "double jabbed", it is the unvaccinated who are left to catch and spread this virus. This throws the spotlight on to children, teenagers and schools. We can see t
Antarctic expedition to renew search for Shackleton's ship Endurance
Endurance22 will launch early next year with aim of locating and surveying wreck in the Weddell Sea The location of Sir Ernest Shackleton 's Endurance has been one of the great maritime mysteries since the ship became trapped in ice and sank in 1915. Finding this symbol of the "heroic age" of polar exploration at the bottom of the Weddell Sea was long thought impossible because of the harshness o
CDC Warns Americans Not to Have Diarrhea in the Pool
The US Centers for Disease Control has a frank (and gross) warning for Americans this summer: Don't use the pool if you have diarrhea. On Thursday, the CDC tweeted out their warning to not swim if you're experiencing the effects of diarrhea and other intestinal-related illnesses this summer. The tweet linked to their guidance on what to do to protect yourself against poop in the pool. "Don't swim

You Really Need to Quit Twitter
I'm almost 60, and in these many decades I've seen people—some of them good friends—taken down by all kinds of things. Alcohol and drugs, mostly. A few years ago, I lost someone to heroin, and hundreds of us sat at his funeral in wordless communion. I know a couple of people who couldn't shake gambling, and many plagued by food and sex and all the other great distractions. But in all these years—
A Volcano, a Fishing Boat, and a Narrow Escape
On the evening of August 6, 2008, on a remote island in Alaska's Aleutian chain, the side of a volcano began crumbling into the turquoise waters of its crater lake. Gulls fled from the falling rock. The wind whistled around Chris Ford as he peered over the lip of the crater. "It's starting to get tumbling down pretty good," he shouted into his radio. Ford had climbed up the volcano's steep slope
Starwatch: we've got aphelion the sun's further away
At the furthest point in its orbit, Earth is now 5m kilometres more distant from the sun than in January Today the Earth reaches the furthest point in its orbit around the sun. We are about 5m kilometres more distant from our central star than we were in early January. This happens because Earth's orbit is mildly elliptical in shape. The point at which Earth is furthest from the sun is known as a
McDonald's is replacing human drive-thru attendants with AI
This article was originally published on our sister site, Freethink. As if drive-through ordering wasn't frustrating enough already, now we might have a Siri-like AI to contend with. McDonald's just rolled out a voice recognition system at 10 drive-throughs in Chicago, expanding from the solitary test store they launched a few years ago. But when will it come to your neighborhood Golden Arches? "

Why do powerful men have affairs?
After Matt Hancock was forced to resign when a secret relationship was exposed, the couples therapist Orna Guralnik explores the cocktail of ego and vulnerability that leads some senior figures to risk it all The images of Matt Hancock and Gina Coladangelo splashed across newspaper front pages in June were shocking enough to cause a scandal, and the breach of his own social distancing rules ended
Climate crisis causing male dragonflies to lose wing 'bling', study finds
Black patterns used to attract mates can cause the insects to overheat in hotter climates Male dragonflies are losing the "bling" wing decorations that they use to entice the females as climates get hotter, according to new research. The results have led to the scientists calling for more work on whether this disparate evolution might lead to females no longer recognising males of their own speci
The Problem With the Stories We Tell About Eating Disorders
Over the past several years, depictions of eating disorders have become more common on-screen and in literature. Think of Lily Collins's thin frame as she counts calories in the Netflix film To the Bone , or the young protagonist of the series Insatiable , who becomes skinny after a summer on a liquid diet. Sarai Walker's novel Dietland is a satirical look at a woman radicalized after years of fa
Graphene for the protection of paintings: paving the way for novel methods in art preservation and restoration
The exposure of colors used in artworks to ultraviolet (UV) and visible light in the presence of oxidizing agents triggers color degradation, fading and yellowing. These degradation mechanisms can lead to irreversible alteration of artworks. Protective varnishes and coatings currently used to protect art paintings are not acceptable solutions, since their removal requires the use of solvents, whic
The Heaviest, Lightest Thing
T he last time a Democrat lived in the White House, I was nearly detained outside of its gates. It should have been obvious to me, an undocumented immigrant, that giving my blank passport to a Secret Service agent could get me in trouble. But I, along with a classmate, had been asked to be there for a meeting about college access hosted by first lady Michelle Obama's higher-education initiative,
Europa Clipper to determine whether icy moon has ingredients necessary for life
In 1610, Galileo peered through his telescope and spotted four bright moons orbiting Jupiter, dispelling the long-held notion that all celestial bodies revolved around the Earth. In 2024, when scientists expect to send the Europa Clipper spacecraft to investigate one of those moons, they too may find evidence that fundamentally alters our understanding of the solar system.
Geoscientists reveal icy crystal structures of hailstones
The Tübingen region has recently seen hailstorms that brought back memories of the devastating storm of 2013. At that time, billions of dollars in damage were caused, and the damage from the most recent storms is still being assessed. Despite all the trouble hailstones cause, they also possess a previously unknown inner beauty. In a recent study, Tübingen geoscientists Professor Paul Bons and Dr.
A 30% reduction in Wisconsin's wolf population
About 100 additional wolves died over the winter in Wisconsin as a result of the delisting of grey wolves under the Endangered Species Act, alongside the 218 wolves killed by licensed hunters during Wisconsin's first public wolf hunt, according to new research.

Sculpted by starlight: A meteorite witness to the solar system's birth
In 2011, scientists confirmed a suspicion: There was a split in the local cosmos. Samples of the solar wind brought back to Earth by the Genesis mission definitively determined oxygen isotopes in the sun differ from those found on Earth, the moon and the other planets and satellites in the solar system.
A small satellite with a solar sail could catch up with an interstellar object
When 'Oumuamua, the first interstellar object ever observed passing through the solar system, was discovered in 2017, it exhibited some unexpected properties that left astronomers scratching their heads. Its elongated shape, lack of a coma, and the fact that it changed its trajectory were all surprising, leading to several competing theories about its origin: was it a hydrogen iceberg exhibiting o
Male dragonflies lose their 'bling' in hotter climates
A study published the week of July 5 in the Proceedings of the National Academy of Sciences led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates.
How fish got their spines
In the movie "A Fish Called Wanda," the villain Otto effortlessly gobbles up all the occupants of Ken`s fish tank. Reality, however, is more daunting. At least one unfortunate fan who re-enacted this scene was hospitalized with a fish stuck in the throat. This was also was a painful lesson in ichthyology (the scientific study of fishes)—namely that the defense of some fishes consists of needle-sha
Color and flavor: Pigments play a role in creating tasty tomatoes
Researchers have found that pigments controlling the color of tomatoes also play a role in determining their flavor. By analyzing the pigment profiles of 157 different tomato varieties, the team showed that fruit with high chlorophyll levels had a higher sugar content, and that the carotenoid, prolycopene, is associated with an abundance of aroma compounds. Understanding how growing conditions inf
Elitskidåkare drabbas ofta och tidigt av andningsbesvär
Mer än var fjärde skidåkare vid riksidrottsgymnasierna har astma, det är betydligt fler än andra i samma ålder.

En stor andel av elitskidåkare har dessutom ytterligare en luftvägsåkomma, en ansträngningsutlöst övergående obstr
Jämlikhet och sociala nätverk ett måste för att hantera värmeböljor
Att hantera extrem hetta handlar om mer än tekniska lösningar som kylrum, tillgång till vatten, gröna områden och kommunikationssystem. Minst lika viktigt är att stärka sociala nätverk, minska inkomstskillnader och bygga bort social utsatthet. Det menar hållbarhetsforskaren Maryam Nastar, som kommenterar värmeböljan i Kanada och Nordamerika utifrån sin forskning om extremväder. Hon har nyligen an
Sleep deprivation affects fertility, memory, and even your immune response after a vaccine
How well did you sleep last night? And how has that affected the way you feel today? Most of us will have experienced poor sleep or even insomnia at some point and know all too well how it leaves you feeling. What might be less well known is how much you benefit from getting enough sleep. Not only will you wake up feeling refreshed and ready to take on the day, your mental and physical wellbeing
Global BECCS potential is largely constrained by sustainable irrigation
Bioenergy with Carbon Capture and Storage (BECCS), a negative emission technology, has been considered inevitable to achieve the 2°C or 1.5°C climate goal. Although numerous studies have been conducted, the effect of irrigation remains largely unexplored when taking water use sustainability into consideration. A new study finds that although unlimited irrigation could increase the global BECCS pot
Underground microbial solutions to aboveground plant problems
Land plants—those that live primarily in terrestrial habitats and form vegetation—are anchored to the ground through their roots, and their performance depends on both the underground soil conditions and the aboveground climate. Plants use sunlight to grow through the process of photosynthesis where light energy is converted to chemical energy in chloroplasts, the powerhouses of plant cells. There
Hunting and hidden deaths led to 30% reduction in WI wolf population
About 100 additional wolves died over the winter in Wisconsin as a result of the delisting of grey wolves under the Endangered Species Act, alongside the 218 wolves killed by licensed hunters during Wisconsin's first public wolf hunt, according to new research. A majority of these additional, uncounted deaths are due to cryptic poaching, where poachers hide evidence of illegal killings.

The result was published in Nature Communications and
A Nanowire Network That Mimics the Brain Could Inspire New Designs in AI
The neural networks that power today's leading AI systems can vastly outperform the human brain when it comes to picking out patterns in large tracts of static data. But w hen there's little data to learn from or the data streams vary dynamically over time, they tend to struggle. This is where the human brain shines, though, which has led many researchers to try to borrow some of its design princ
"Gärna mer utforskning av oidentifierade fenomen, men mindre prat om utomjordingar"
Det här är en kommenterande text. Analyser och åsikterna i texten är skribentens egna. KOMMENTAR. Alla vet vad ett ufo är. Det första som dyker upp i huvudet när den förkortningen nämns är ett flygande tefat med små gröna utomjordingar i.

A multidisciplinary research team, led by the CSIC biologist at CRAG, Ana I. Caño Delgado, and the physicist from the University of Barcelona, Marta Ibañes, has discovered that two plant stem cell proteins, known for their role in the correct development of the root, physically interact and regulate each other to avoid cellular division. The study, result of fifteen years of continued research car
Jacque Fresco has hidden or censored video/videos.
Hi. Back in 2017 I first met Jacque Fresco. I knew him before, but not on his terms, wasn't able to perceive his message. There was a video, an introductious video, where he's talking about how a man cannot think or reason and explains how all he has is an associative memory. But I can't seem to find it anymore. Not on the Venus Project channel, Russian volunteer, or other channels. I've seen a s
Russia's first cloned calf opens door to gene-edited cattle
Researchers from Ernst Federal Science Center for Animal Husbandry, Skoltech, Moscow State University and their colleagues have produced the first viable cloned calf in Russia—and she recently turned one. In a related experiment, the team was able to knock out the genes responsible for beta-lactoglobulin, a protein causing milk allergy in humans, in the hopes of creating gene-edited cows with hypo

Piezoelectric microelectromechanical system-based optical metasurfaces
Optical metasurfaces can unprecedently regulate versatile wavefronts at the subwavelength scale. Most well-established optical metasurfaces are, however, static and feature well-defined optical responses that are determined by optical metasurface configurations set during their development. The dynamic configurations of the materials investigated so far often show specific limitations and reduced
It's all about the interface with multi-use polymer brushes
The University of Newcastle and UNSW Sydney are using advanced neutron scattering techniques at ANSTO to carry out research on the structure of polymers in complex salt environments that will ultimately provide a way to predict their behaviour for real-world applications.
Organic foods not always free from pesticides
As consumers, we've been conditioned to believe that organic foods are free from hormones and pesticides. Walk into any supermarket, you will find fresh produce, canned foods, poultry, and even personal hygiene products labelled as 'organic'.

Researchers discover why gold is concentrated alongside arsenic
Why are gold deposits found at all? Gold is famously unreactive, and there seems to be little reason why gold should be concentrated, rather than uniformly scattered throughout the Earth's crust. Now, an international group of geochemists have discovered why gold is concentrated alongside arsenic, explaining the formation of most gold deposits. This may also explain why many gold miners and others
