The late persistence in Southern Iberia of a Neandertal-associated Middle Paleolithic is supported by the archeological stratigraphy and the radiocarbon and luminescence dating of three newly excavated localities in the Mula basin of Murcia (Spain).
Do we have the courage to act now?
New research casts doubt on a gene-editing strategy that scientists had hoped to use against invasive species and epidemic diseases.
A Department of Homeland Security official admitted that a team of experts remotely hacked a Boeing 757 parked at an airport.

Per a press release from the Centro Nacional de Control de Energía (Cenace) of Mexico, the department received bids for 3TWh of solar electricity, with the lowest bids being 1.77¢/kWh coming from Italian multinational ENEL Green Power. This record low price of electricity on earth, just beats out the 1.79¢/kWh from Saudi Arabia, and is part of a pattern marching toward 1¢/kWh bids that are coming in 2019 (or sooner).
Glitter, as anyone who has ever worn it knows, has a habit of turning up in unexpected places days later, even after a good scrub. However, a new peril has emerged from the sparkly substance: it is adding to the plastic pollution in our seas. A group of nurseries in southern England has banned the use of glitter among its 2,500 children to reduce the amount of microplastics entering the seas. Harriet Pacey, the business development director at Tops Day Nurseries, a 19-strong chain, said: “We want to do something we have control over.”
Bet you've never seen fruits and veggies that look like these before.
Leading researchers castigated a federal plan that would use artificial intelligence (AI) methods to scrutinise immigrants and visa applicants, saying it is unworkable as written.
Scientists have successfully performed a head transplant on a corpse, and are ready to do it on a living person, according to the man famous for promising it. Surgeon Sergio Canavero has become famous for claiming to be working on the first human head transplant. And he says that the successful test shows that his plans will work. The successful transplant on the corpse shows that his newly developed techniques for re-connecting the spine, nerves and blood vessels to allow the two bodies to live together will work, he said.
There’s been serious talk of late about sending people to Mars, the goal of which is to establish a permanent colony on the Red Planet, perhaps within the next decade. Assuming astronauts can survive the six-month-long journey in one piece, human life in the lethal Martian environment presents its own challenges. Sustainable habitation requires shelter, water, food and recreation, none of which exist on Mars in any usable form...
Something that often bothers me about sci-fi is the loner inventor trope. A guy in a garage builds a robot, or AI, or frequently both that are somehow decades beyond the technology of his day, and all the wild implications of his vast technological leap are the fuel for the next two and a half hours of popcorn entertainment.
Lukas Pilkey was so excited last week he could have leaped over the moon. The Shiloh 6-year-old got to meet one of his heroes — retired Air Force Col. Edwin “Buzz” Aldrin. “It was really cool,” Lukas said with an ear-to-ear smile while donning a T-shirt with an astronaut on it. Lukas, his parents, Greg and Aerica Pilkey, and Aerica’s dad, Mike Dreps, stood in line for over three hours on Wednesday, Nov. 15 to get into the Center for Global Citizenship at St. Louis University to hear the famous astronaut speak.
Even after more than 27 years in space, the Hubble Space Telescope can still take one heck of a photo. The image above was taken earlier this year and shows two galaxies merging into one. Described by the European Space Agency and NASA as a "twisted cosmic knot" in the constellation Cancer, it's about 250 million light-years from earth.
An aircraft and a helicopter have crashed in mid-air over Buckinghamshire, the Air Accidents Investigation Branch (AAIB) said. Emergency services were called to the site near Waddesdon Manor, near Aylesbury, at 12:06 GMT. The AAIB said it was sending a team to investigate. Ambulance crews said there had been a number of casualties. A Wycombe Air Park spokesman said both aircraft involved came from the airfield near High Wycombe.
New results from an unconventional observatory in Mexico are bringing scientists one step closer to solving the dark matter mystery. They lend credence to the idea that some strange non-light-emitting particle is responsible for about 85% of the universe’s mass. This new observation casts serious doubt on the more conventional of two favored theories for the enigmatic excess of antimatter particles in space, leaving dark matter particles as the most likely explanation.
Severe emotional stress can prompt a sudden heart condition that poses the same sort of long-term damage as a heart attack, new research has found. Takotsubo cardiomyopathy – or “broken heart syndrome” - affects at least 3,000 people in the UK and is typically triggered by traumatic life events such as bereavement. During an attack, the heart muscle weakens to the point where it can no longer function as effectively.
Synthetic biologists are fitting the genomes of microorganisms with synthetic gene circuits to break down polluting plastics, non-invasively diagnose and treat infections in the human gut, and generate chemicals and nutrition on long haul space flights. Although showing great promise in the laboratory, these technologies require control and safety measures that make sure the engineered microorganisms keep their functional gene circuits intact over many cell divisions, and that they are contained to the specific environments they are designed for.
Last July, the world saw the amazing satellite images that showed an iceberg bigger than the state of Delaware drifting away from Antarctica’s ice shelf. Now it’s summertime in Antarctica, which is allowing scientists to view the massive ice structure up close. According to Gizmodo, the ice behemoth is known as “iceberg A-68” and weighs “about a trillion tons and features a surface area of 2,240 square miles (5,800 square kilometers).”
Although it may be years before brain-computer interface (BCI) technology becomes part of daily life, a team of experts is calling for conversation on the ethics of the field to begin. The demand comes from a group of neuroscientists, neurotechnicians, clinicians, ethicists, and engineers called the Morningside Group. Their concerns about the technology range from data privacy minutiae to science-fiction nightmare. They say existing ethical guidelines are insufficient.
It’s difficult to imagine the voracious great white shark as prey. Could orcas really be overpowering them and removing their livers?
Gene drive raises hopes and fears as scientists are using it to wipe out the mosquitoes that carry malaria, to eradicate the disease.
The nation wants to eradicate all invasive mammal predators by 2050. Gene-editing technology could help—or it could trigger an ecological disaster of global proportions.
The UK and Canada have launched a global alliance of 20 countries committed to phasing out coal for energy production. Members including France, Finland and Mexico, say they will end the use of coal before 2030. Ministers hope to have 50 countries signed up by the time of the next major UN conference in Poland next year.
In an excerpt from Spaceport Earth: The Reinvention of Spaceflight, author Joe Pappalardo explores how one errant rocket helped create the U.S.'s most important spaceport.
Doctors in Europe used gene therapy to grow sheets of healthy skin that saved the life of a boy with a genetic disease that had destroyed most of his skin, the team reported on Wednesday in the journal Nature. This was not the first use of the treatment, which adds gene therapy to a technique developed to grow skin grafts for burn victims. But it was by far the most body surface ever covered in a patient with a genetic disorder: nine square feet.
It was summer in Antarctica, and Erik Gulbranson and John Isbell were on the hunt. Bundled up in parkas to brave negative temperatures, fierce winds, and blinding days of 24-hour sunlight, Gulbranson, Isbell, and an international team of researchers searched for fossil fragments. Between November 2016 and January 2017, they scaled the snow-capped slopes of the McIntyre Promontory high above the ice fields and glaciers, sifting through the Transantarctic Mountain's gray sedimentary rocks for clues.
UN climate negotiators are meeting in Bonn amid a welter of reports indicating that concentrations of carbon dioxide in the atmosphere have broken records, while international attempts to curb greenhouse gases are not doing enough to avoid dangerous levels of warming. Our environment correspondent Matt McGrath has travelled to Switzerland to see if technology to remove CO2 from the air could be the answer to this ongoing carbon conundrum.
Next-generation agriculture requires immense computing power. Learn how supercomputing and bioinformatics help scientists adapt agricultural practices to feed 9 billion people.
A 3-year-old girl was the only survivor of a plane crash in far eastern Russia, which killed six people Wednesday, officials said. An L-410 twin-engine turboprop crashed while trying to land at a small airport near the village of Nelkan. The aircraft, which belonged to regional carrier Khabarovsk Airlines, was on a regular flight to Nelkan from Khabarovsk, the regional center which is near a border with China.
Animals from the deepest places on Earth have been found with plastic in their stomachs, confirming fears that manmade fibres have contaminated the most remote places on the planet. The study, led by academics at Newcastle University, found animals from trenches across the Pacific Ocean were contaminated with fibres that probably originated from plastic bottles, packaging and synthetic clothes.
Stillbirth and newborn death risk could be reduced by offering more pregnant women the chance to give birth on their due date, experts believe. Currently, women who are overdue but well are often given a couple of extra weeks to see if labour will happen spontaneously before doctors intervene. New research suggests bringing forward induction to 40 weeks' gestation may be a safer option for mothers and babies.
You need more than just critical analysis skills—you need to value using them.
The moon landing and global warming are hoaxes. The U.S. government had advance knowledge of the 9/11 attacks. A UFO crashed in Roswell, New Mexico. Is skepticism toward these kinds of unfounded beliefs just a matter of cognitive ability?
By replacing black holes with fuzzballs — dense, star-like objects from string theory — researchers think they can avoid some knotty paradoxes at the edge of physics. By Jennifer Ouellette.
Daughters who grow up with fathers who disappointed them are more likely to interpret the intentions of other men as sexual when they grow up, new research suggests. The study is the latest installment from a team of researchers who have previously studied how fathers impact their daughters’ odds of risky sexual behaviors and the particulars of so called “daddy issues”. But this is the first time scientists have demonstrated that...

Byzantine civilization, the eastern Roman empire whose capital was at Constantinople, is mostly known today for its spirituality and eccentricities. In reality, Byzantium was also a pragmatic and down-to-earth culture, and it also exhibited prowess in science and technology. By Anthony Kaldellis.
When a SpaceX Dragon spacecraft connected with the International Space Station on May 25, 2012, it made history as the first privately-built spacecraft to reach the ISS. The Dragon was the result of a decision 6 years prior—in 2006, NASA made an "unprecedented" investment in SpaceX technology. A new financial analysis shows that the investment has paid off, and the government found one of the true bargains of the 21st century when it invested in SpaceX.
