Imagine a bottle of laundry detergent that can sense when you’re running low on soap—and automatically connect to the internet to place an order for more.



University of Washington researchers are the first to make this a reality by 3-D printing plastic objects and sensors that can collect useful data and communicate with other WiFi-connected devices entirely on their own.

Beresheet’s moon crash was the first in nearly half a century. But back in the day, moon crashes happened all the time.


Crash debris from the uncrewed Israeli lander Beresheet will remain permanently on the lunar surface after SpaceIL’s effort to land on the moon failed Thursday (April 11). It was a disappointment for the program and a setback for the private Israeli company’s efforts to join the small community of organizations that have successfully landed on Earth’s nearest neighbour. But it wasn’t the first time that a robotic moon landing failed in this way.

New simulations reveal a new state of matter that displays characteristics of both liquid and solid states.


A new kind of matter can be both solid and liquid at once.

In this chain-melted state, molten and solid layers intertwine at the atomic level. Recently, using computer simulations, researchers coaxed virtual potassium into a chain-melted state by exposing the metal to conditions of extreme temperature and pressure, the scientists reported in a new study.

What’s more, this dual state persisted even through dramatic changes in the experiments’ conditions within the simulation. This evidence also showed that the chain-melted state is a stable type of matter and not merely a transition between solid and liquid. [The 18 Biggest Unsolved Mysteries in Physics]

Researchers are developing a probiotic to make disease-causing bacteria self-destruct.


As resistance to antibiotics grows in the U.S., researchers are looking for new ways to fight germs like Clostridium difficile, a bacterium that can cause fatal infections in hospitals and nursing homes.

One way to do that: a “CRISPR pill” that instructs harmful bacteria to self-destruct.

CRISPR is the powerful gene-editing technology already being explored as a way to precisely edit human genes to cure diseases (see "Can CRISPR Save Ben Dupree?"). But the technology’s versatility is such that it’s being studied for a huge range of other uses. Just last week scientists in Boston showed they could craft CRISPR into cheap, simple diagnostic tests.

Now scientists want to turn it into ultra-precise antimicrobial treatments to “specifically kill your bacteria of choice,” says food scientist Jan-Peter Van Pijkeren of the University of Wisconsin-Madison.
