If you were monitoring a security camera and saw someone set down a backpack and walk away, you might pay special attention – especially if you had been alerted to watch that particular person. According to Cornell researchers, this might be a job robots could do better than humans, by communicating at the speed of light and sharing images.

The Trump administration is reviewing design bids for its proposed wall along the US-Mexico border. But not all plans are interpreting the word “wall” literally.

Researchers in the US say they’ve created a fluid with negative mass in the lab… which is exactly as mind-bending as it sounds.
What it means is that, unlike pretty much every other known physical object, when you push this fluid, it accelerates backwards instead of moving forwards.
A new reconfigurable device that emits patterns of thermal infrared light in a fully controllable manner could one day make it possible to collect waste heat at infrared wavelengths and turn it into usable energy.
Imagine a future in which every home has an appliance that pulls all the water the household needs out of the air, even in dry or desert climates, using only the power of the sun.
Pesticides based on fungi are just one example of biopesticides, a group that also includes bacteria and biochemicals derived from plants.
Biopesticides are a tiny segment of the market for now – but their use is projected to grow at a faster rate than traditional synthetic pesticides over the next few years.
A team of researchers at an Israeli university has successfully tested a technology using fluorescent bacteria and lasers that could become a safer system for detecting buried landmines.
An estimated 100m landmines are scattered in some 70 countries, a legacy of often long-past conflict, and the devices injure up to 20,000 people a year.
Getting enough toxic material to the right place in your body for it to kill tumours – while not damaging anything else – has always required thinking outside of the box.
Remember last year when Google released an AI-powered web tool that played Pictionary with your doodles? Well, surprise! Those doodles you drew have now been used to teach Google’s AI how to draw.
In the search for new physics, experiments based on high-energy collisions inside massive atom smashers are coming up empty-handed. So physicists are putting their faith in more-precise methods: less crash-and-grab and more watching-ways-of-wobbling.
The study concludes that screening does not stop the advance of breast cancer and that nearly one third of the tumours diagnosed in women offered screening are actually overdiagnosis.
This means that healthy women who would never have become ill from breast cancer are operated on and exposed to radiotherapy and possibly chemotherapy.

Engineers have now succeeded in producing complex crystal lattices, so-called clathrates, from nanoparticles using DNA strands. The programmed synthesis of clathrates represents a template for the precision modelling of novel nanomaterials.
Last fall, the New York-based reproductive endocrinologist John Zhang made headlines when he reported the birth of the world’s first “three-parent” baby — a healthy boy carrying the blended DNA of the birth mother, her husband and an unrelated female donor.
Are we on the cusp of the consumer biotech age, when lab-grown meat will be just as common as farmed meat? Recently, a company called Memphis Meats started selling in-vitro meat (IVM) that apparently tastes just like delicious chicken and duck. But if we want the price on an IVM burger to get below $1,000, we need consumers to buy lots of the stuff.
A sci-fi staple for decades, laser weapons are finally becoming reality in the US military, albeit with capabilities a little less dramatic than at the movies.
“Sock puppets” are the scourge of online discussion . Multiple accounts controlled by the same user can dominate comment forums and spread fake news. But now there’s a way to unmask the puppeteers.
A study of nine websites that use comment service Disqus to let readers post responses to articles found that sock puppets can be identified based on their writing style, posting activity and relationship with other users.
Meet SAM — short for Semi-Automated Mason — created by the New York based Construction Robotics. SAM is capable of laying 3,000 bricks per day, and he is coming to the U.K. in a few months.
SAM can work about 500 percent faster than humans, and discrepancy in labor cost that causes is significant.
