Wild Killer Whales (Orcinus orca) used prey and other items to instigate interactions with humans. Offering items to humans could simultaneously include opportunities for killer whales to practice learned cultural behavior, explore, or play and in so doing learn about, manipulate, or develop relationships with us.

Astronomers have witnessed the birth of a #planetary system that could one day resemble the solar system. The discovery offers scientists a proxy to study how our home planetary system formed around the sun around 4.6 billion years ago.

The team was able to pinpoint the moment specks of material that will one day forge planets began to form around the infant star HOPS-315, located around 1,300 light-years away.

In the new study, researchers sampled a different section of #rock from the belt and estimated its age using the previous two dating techniques — measuring how one radioactive element decays into another over time. The result: The rocks were about 4.16 billion years old.

#Earth formed about 4.5 billion years ago from a collapsing cloud of dust and gas soon after the solar system existed.

In the early Bronze Age, a piece of bread was buried beneath the threshold of a newly built house in what is today central Turkey.

Scientists believed that plants lost most of their water through their pores to cool down. They could then simply close these pores in extreme heat.

The study, published in the scientific journal New Phytologist in December, shows that with rising temperatures, plants lose more water through their cuticle, the waxy layer on their leaves, than through their pores. The thinner the cuticle, the greater the water loss.
