Scientists have figured out how what key identifying trait for humans is formed?
Scientists have found that three interacting molecules cause fingerprint ridges to form their signature stripes. The way those ridges spread from their starting points — and then merge — determines the overarching shape of a fingerprint.
Fingerprints are the looping, swirling stripes on the tips of your fingers. These raised ridges of skin develop before birth. They were known to expand out from three spots on each fingertip: under the nail, in the center of the finger pad and the crease of the joint closest to the tip. But no one knew what determined a fingerprint’s final pattern.

As more carbon dioxide seeps into the ocean and the water becomes more acidic, it's degrading one of the most important senses crabs use to find food. What sense is being impacted?
Smell
Dungeness crabs have poor eyesight, so they rely strongly on their sense of smell to detect food and predators in the water. Each crab has a set of small, waving antennae that help them sniff out chemical signals in the water. When the crab encounters an important scent, it begins flicking its antennae faster to help it process the signal.
When the researchers examined the antennae, they found that increased CO2 levels appear to interfere with the nerve response that prompts the faster flicking.

On Monday, A grapefruit-sized metallic object fell from the sky, straight through the roof of a home where?
A grapefruit-sized metallic object fell from the sky, straight through the roof of a New Jersey home, and crashed into the floor of the bedroom on Monday, according to local reports.
Police who responded to the incident in Hopewell, New Jersey, believe the falling object may be a meteorite, possibly from the Eta Aquarids meteor shower, which peaked this weekend.

Is peanut butter considered a solid, liquid, or gas?
Peanut butter is actually a great example of a non-Newtonian fluid (aka liquid) because it doesn’t flow as easily as air or water but will flow if sufficient force is applied, such as when a knife spreads it on bread. How easily it flows will also depend on temperature

What happened this past weekend that will most likely impact the Earth today (May 11)?
A coronal mass ejection from the Sun is set to hit Earth on Thursday at a speed of 3.6 million kilometers per hour (kmph) as it travels outwards through the inner planets.
The plasma is expected to trigger a strong G3-class geomagnetic storm as it slams into Earth's strong magnetic field and is likely to cause bright auroras.

During a spacewalk this week, what did a cosmonaut do that upset folks here on Earth?
About 6.5 hours into the spacewalk, Sergey Prokopyev tossed an 11-pound bag of leftover equipment into space. "It flies beautifully," the cosmonaut said as it sped into the dark void.
Some felt he "littered" in space but NASA tweeted shortly after the event that the bundle was harmless because it will just burn up in Earth's atmosphere
