Quote: The Double Asteroid Redirect Test spacecraft, otherwise known as DART, will be used as a battering ram to crash into an asteroid not far from Earth on Sept. 26. The mission is an international collaboration to protect the globe from future asteroid impacts. "Facts are whatever I say they are." - Trump

Scientists have discovered extra-terrestrial water in a meteorite for the first time. The meteorite was discovered after it crashed into a driveway in the Gloucestershire town of Winchcombe last February.

I was always told that dogs don't see color at all, but live in a visual world similar to black and white TV. That may have been all that was known back in the day, but at least now we know that is not exactly correct. What is still correct, I think, is that smell is as important as vision to a dog. The article says they are near-sighted but pick up motion well. And our superiority in vision such as it is only applies in the daytime, dogs see much better at night than we do .

Evidence you should eat more early and in a 10 hour period?

Quote:
Eating relatively early may be beneficial for weight loss, and keeping meals within a 10-hour period could improve blood sugar and cholesterol levels, according to two small studies published Tuesday in the journal Cell Metabolism.

The first study found that eating on a later schedule made people hungrier over a 24-hour period than when they consumed the same meals earlier in the day. Late eating also led the study participants to burn calories at a slower rate, and their fat tissue seemed to store more calories on a later eating schedule than an early one. Overall, the study suggests that eating later can increase a person's obesity risk.

The second study, done among a group of firefighters, found that consuming meals within a 10-hour window shrunk "bad cholesterol" particles — suggesting a potential reduction in risk factors for heart disease. That eating window also improved blood pressure and blood sugar levels among firefighters with underlying health conditions such as diabetes, high blood pressure and high cholesterol.

The two studies add to existing evidence that there may be optimal times to start and stop eating, according to Courtney Peterson, an associate professor of nutrition sciences at the University of Alabama at Birmingham who wasn’t involved in either study.

Researchers at Heriot-Watt University in Edinburgh have constructed an AI-powered robot trained to kill pesky cockroaches with a deadly laser.

While the engineers behind the machine say that their invention could be used to target a variety of unwanted bugs, they believe roaches are the ideal test subject.
"If you can kill them," Ildar Rakhmatulin, the project's lead, told New Scientist, "you can kill any pests."

Here's how it works. The device, which is comprised of a tiny computer, two cameras, and a 1,600 milliwatt laser, uses "machine vision" to hunt its prey.
While trials thus far have been promising — the device can only barely keep up with the roaches— the researchers say there's some room for improvement. Next steps, they told New Scientist, are training the robot to hit the insects' specific body parts, specifically their abdomens, in order to ensure their defeat. Better safe than sorry.

It can cause eye injuries, so it’s not exactly completely safe.
