An analysis of flight data shows that problems began at a point when the pilot would normally have engaged the autopilot system.
Gene editing a fertilized human embryo.
Scientists worldwide are calling for a moratorium on gene editing in germline cells. But what is a germline cell? How does it differ from other cells in our body? Why does it matter if we edit them?
Milling grain meant less wear and tear on neolithic teeth, which had other effects on language.
Considering language from a biological perspective led researchers to the idea that new food processing technologies affected neolithic human beings' jaws – and allowed new language sounds to emerge.

CEO Mark Zuckerberg's claimed intent to focus on privacy will be hard to execute, will not happen soon and does not address major concerns about the company's role in society.
The science of getting quickly and safely to the bottom.
In many cities, convention holds that there's a lane for walking and a lane for standing on the escalator. But human systems engineers suggest this isn't the most efficient option for the system.
Two small figures guard the table holding the Buddha’s relics. Are they spearmen, or robots?
Stories passed down from the ancient world tell of self-powered machines able to move on their own – robots – playing key roles in historic moments.
The orientations of the stone walls that crisscross the Northeastern U.S. can tell a geomagnetic tale as well as a historical one.
Scientific inspiration struck a geologist after many walks through the woods in New York and New England. These ruins hold the secret of where the compass pointed north when they were built centuries ago.
The U.S. military is shifting the focus of its cyberwarfare forces.
U.S. Air Force
A new strategy for U.S. Cyber Command seeks to block enemies from achieving their objectives – but may not be successful, and could have unforeseen consequences.
Let’s work together.
People – individually and in groups – were not as good at facial recognition as an algorithm. But five people plus the algorithm, working together, were even better.
New technology means accessing new information from ancient human remains, some which have been in collections for decades.
Ancient DNA allows scientists to learn directly from the remains of people from the past. As this new field takes off, researchers are figuring out how to ethically work with ancient samples and each other.

Researchers have found a way to evaluate how energy-efficient electric vehicles are, and compare the sizes and costs of batteries for different models.
Libraries subscribe digitally to academic journals – and are left with nothing in the stacks when the contract expires.
Digital publishing hasn't resulted in the free and open access to information many envisioned. Universities are increasingly fed up with a system they see as charging them for their own scholars' labor.
Sometimes the questions become too much for artificial intelligence systems.
When algorithms are at work, there should be a human safety net to prevent harming people. Artificial intelligence systems can be taught to ask for help.
The human immunodeficiency virus (HIV), shown here as tiny purple spheres, causes the disease known as AIDS.
Mark Ellisman and Tom Deerinck, National Center for Microscopy and Imaging Research
Headlines around the world declared that a second person was cured of their HIV. But while the results are encouraging, we're a long way from a cure.
What is each partner looking to get?
The interests of pharmaceutical companies and public health are not the same. Industry dollars can distort research agendas, while framing health challenges and solutions in ways that benefit corporations.
Artist’s depiction of a moon base with a view of Earth in the distance.
Scientists are figuring out how to reduce the cost of space travel – to and from the Moon and possibly to Mars. One approach is to mine the Moon for resources necessary for interplanetary travel.
Are there people down there who need help?
Drones already help with search and rescue, but teaching machines to identify victims on their own could free up human rescuers to do other crucial work.
The Periodic Table of the Elements.
Hydrogen is the first element in the periodic table and essential for life on Earth. It may also be key to shifting away from fossil fuels toward clean sources of energy, but challenges remain.
Minutes after launching the Falcon Heavy rocket, SpaceX was livestreaming footage from the Tesla Roadster it released into space.
SpaceX's advances in space technology have reduced barriers to space and changed the direction of American space policy, but it is not without its challenges.
Padaungiella lageniformis wiggles its pseudopods.
Daniel J. G. Lahr
Using the family relationships between single-celled protists alive today, researchers hypothesized what their evolutionary ancestors looked like – and then looked in the fossil record for matches.
Signals from inside the brain can reveal what’s happening in nerve cells.
When nerve cells in the brain pass electrical signals to each other, they create tiny electric fields that can be sensed from outside the skull.
The U.S. may be ahead for now, but not by much.
A recent executive order from President Trump won't do much to help the US stay ahead of Chinese innovation and investment in AI.
World’s first lab-grown beef burger. Would you eat it?

In the eastern reaches of Siberia, scientists discovered plants with exceptional cold tolerance that could be the key to sustainable bioenergy production.
Caller ID won’t always tell you it’s a robot doing the dialing.
Robocalls are common and becoming increasingly frequent. A scholar explains how they work, and why they're such a pain.
