It’s the first step toward being able to mass produce human eggs using other people’s body tissues or blood.

A Silicon Valley startup called New Age Meats offered us a taste of the world's first pork sausage made in a lab without killing any animals. Here's how the cultured meat cooked, smelled, and tasted.

Decades spent studying peer review, publication bias, and more have challenged the status quo, but journalologists say they have a long way to go

It had been hiding in plain sight. The original letter — long thought lost — in which Galileo Galilei first set down his arguments against the church’s doctrine that the Sun orbits the Earth has been discovered in a misdated library catalogue in London. Its unearthing and analysis expose critical new details about the saga that led to the astronomer’s condemnation for heresy in 1633.

Scientists at the Cincinnati Children’s Center for Stem Cell and Organoid Medicine (CuSTOM) are working to create the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids. This study could offer new ways to study birth defects and diseases that affect millions of people with gastrointestinal disorders, such as gastric reflux, cancer, etc.

The latest entree to join the Army’s roster of M.R.E. field rations is a Sicilian-style slice that stays fresh for years and took decades to develop.

We love to categorize ourselves and others into personality types. Maybe you’re a “Type A.” Or maybe the Meyers-Briggs Type Indicator, versions of which many have taken on Facebook, labels you a “Protector” (ISFJ). But how distinct are these types? Is everyone clearly Type A or Type B, with no one in between? Or do people fall on a spectrum? If there’s a spectrum, are there two clumps with a few people between, or one clump in the middle with a few people at the extremes?

​Diets like intermittent fasting are proving wildly popular for their rapid weight-loss effects, but scientists are also starting to uncover how they might benefit the body in other ways. A molecule produced during fasting has now been found to apply the brakes to aging of the vascular system.

Physicists took a deeper look at the Leidenfrost effect, which you’ve likely experienced when you’ve dripped water into a pan to test its temperature.

Hugging is a particularly intimate and intense way to express emotions. Through a hug we can convey joy or sorrow, we can say to a person that can count on us unconditionally and understand his state of mind without speaking. But the fact is that embraces not only help us connect with others and express what we feel, also have a very positve effect on the emotional balance and brain health.

A study in mice hints at a new approach for thwarting neurodegenerative diseases—but many questions remain.

From making biofuels to eating up harmful plastics, fungi could help us build a greener planet. Fungi could not just help rid the planet of plastic by degrading it, but by making it obsolete it, too. Research in the Kew report suggests that naturally made materials using fungal mycelia are being used increasingly often instead of more harmful materials such as polystyrene and leather.

A new paper has taken a ingenious route towards treating cocaine addicted mice – by developing a CRISPR-powered skin grafts that produce an anti-cocaine enzyme.

A trio of researchers affiliated with several institutions in the U.S. and Canada has found evidence that suggests nuclear material beneath the surface of neutron stars may be the strongest material in the universe. In their paper published in the journal Physical Review Letters, M. E. Caplan, A. S. Schneider, and C. J. Horowitz describe their neutron star simulation and what it showed.

The universe is filled with billions of massive celestial objects, from stars to planets to comets to asteroids. But what happens when lines start to blur between these classifications, and we just can’t place an object in any major category? Well, brown dwarfs know this better than anyone. They’re far too massive to be planets, but not massive enough for hydrogen atoms to fuse in their cores and become stars.

Scientists agree that the story of the universe began 13.8 billion years ago, when everything — all the matter and energy and even space itself — emerged from the extraordinarily hot, dense cauldron known as the Big Bang. But ask a scientist what came before that first moment, and you’re likely to get a shrug. To many, thinking about a time before the beginning of time makes no sense.

Just a cosmic hop, skip and jump away, an Earth-size planet orbits the closest star to our sun, Proxima Centauri. Ever since the discovery of the exoplanet—known as Proxima Centauri b—in 2016, people have wondered whether it could be capable of sustaining life. Now, using computer models similar to those used to study climate change on Earth, researchers have found that, under a wide range of conditions...

Humans looking back on this period of history in future will be astonished by the huge amount of plastic this generation left behind – because rubbish waste is now so prolific it will become fossilised, a scientist has said. Dr Dan Parsons, professor of sedimentology at Hull University, says that it is inevitable there will be a record of the thousands of tonnes of plastic waste we generate as microplastics are already seeping into the earth and into the food chain.

Targeted engineering projects to hold off glacier melting could slow down the collapse of ice sheets and limit sea-level rise, according to a new study published in the European Geosciences Union journal The Cryosphere. While an intervention similar in size to existing large civil engineering projects could only have a 30% chance of success, a larger project would have better odds of holding off ice-sheet collapse. But study authors Michael Wolovick and John Moore caution that reducing emissions still remains key to stopping climate change and its dramatic effects.

History and literature are filled with warnings about the danger of seeking eternal life. But in the latest episode of Crazy/Genius, some scientists say that a dramatic expansion of human lifespans is within reach.

Those who take on the global industry that traps research behind paywalls are heroes, not thieves, says George Monbiot

A space observatory at the centre of swirling alien conspiracy theories has asked for “patience” as it continues to be locked down. The Sunspot Solar Observatory in Sunspot, New Mexico caught the attention of the world when it was shut down by FBI agents who reportedly swooped on the facility after arriving in elite Blackhawk helicopters. It led immediately to suggestions the advanced technology inside of the facility spotted something it shouldn’t – such as proof of extraterrestrials, UFOs or even some baseless speculation that the observatory had spotted that the sun has started dying.

A strange thing has happened to men over the past few decades: We've become increasingly infertile, so much so that within a generation we may lose the ability to reproduce entirely.

As a type of immune cell, it has always been considered one of the good guys. But in a stunning breakthrough in schizophrenia research, scientists say the "macrophage" immune cell can go rogue, causing havoc in the brain. "Macrophage" means "big eaters" in Greek and is a fitting name for the cell because - when behaving - it digests cellular debris and foreign substances.

Scientists are hoping archaeology, carbon dating, and tree rings together can help solve the mystery.

The Klondike region of Canada is famous for its gold, but now other remarkable ancient treasures have been unearthed from the melting permafrost. Two mummified ice age mammals – a wolf pup and a caribou calf – were discovered by gold miners in the area in 2016 and unveiled on Thursday at a ceremony in Dawson in Yukon territory.

NASA has released the first image from its new space telescope. TESS, short for Transiting Exoplanet Survey Satellite, is helping scientists detect and study new planets in other solar systems. The telescope launched in April on a SpaceX rocket, and on July 25, TESS slipped into a unique orbit between Earth and the moon. The telescope is now scanning the night sky, staring down distant solar systems, and hunting for small, rocky, Earth-like planets.

An unusual visitor has been hanging out in the St. Lawrence River for the past three years: A narwhal, more than 1,000 kilometres south of its usual range. But the lone narwhal is not alone — it appears he has been adopted by a band of belugas. The narwhal — thought to be a juvenile male because of its half-metre-long tusk — was filmed in July playing among a pod of young belugas, thought to be mostly or all males.

If you ship whiskey on a river, does it taste better? We wanted to know, so we ran an experiment.

Videos abound on the internet of people using customized hats and other tools to hand-feed the tiny fliers. Here’s what you need to know if you’d like to try it.

Fusion, the power that drives the sun and stars, produces massive amounts of energy. Scientists here on Earth seek to replicate this process, which merges light elements in the form of hot, charged plasma composed of free electrons and atomic nuclei, to create a virtually inexhaustible supply of power to generate electricity in what may be called a “star in a jar.”

The weird hexagon swirling around Saturn's north pole is much taller than scientists had thought, a new study suggests. Researchers have generally regarded the 20,000-mile-wide (32,000 kilometers) hexagon — a jet stream composed of air moving at about 200 mph (320 km/h) — as a lower-atmosphere phenomenon, restricted to the clouds of Saturn's troposphere.

Dame Jocelyn Bell Burnell will donate the money to help students underrepresented in physics

Artificial Intelligence is a greater concern than antibiotic resistance, climate change or terrorism for the future of Britain, the incoming president of the British Science Association has warned. Jim Al-Khalili, Professor of physics and public engagement at the University of Surrey, said the unprecedented technological progress in AI was ‘happening too fast’ without proper scrutiny or regulation.

Phosphorus, which is vital to life but somewhat rare, condensed inside asteroids in the outer Solar System before moving back towards the sun, where some of it ended up on Earth, according to new research.
