There are several orca subspecies, and scientists initially thought these groups kept mainly to themselves. But genetic evidence alongside distinct tooth marks heavily suggests that one group may occasionally snack upon the other, which could explain why the preyed-upon orcas live in large, tight-knit groups.
Oracle bones reveal climate disaster in ancient China
Climate disasters caused societal upheaval 3,000 years ago in China, study of 'oracle bones' hints
"Oracle bones," made up of 3,250-year-old engraved bones and tortoise shells are the earliest significant evidence of writing in China, and they were once used in attempts to divine the future. But this week, we reported that these bones can also tell us about the past, as they revealed that China's Shang dynasty may have collapsed with the help of mega-typhoons.
Scientists counted the instances of weather-related writing on more than 55,000 pieces of oracle-bone scripts written between 1250 and 1046 B.C. (the dynasty's final two centuries), and found an uptick in divinations related to rainfall and water-related disasters. The findings imply that there was a growing concern toward extreme weather events among people in Bronze Age China.

Why is mercury a liquid?
Metals are often associated with hardness, strength and durability — especially under heating. But one notable exception, mercury, melts at a mere minus 37.9 degrees Fahrenheit (minus 38.8 degrees Celsius). But what makes it so unique? Find out here.

Humming black holes could fix the universe
'Collective hum' of black holes could mend our broken understanding of the universe, physicists say
The Hubble tension, or the finding that the universe seems to be expanding at different rates depending on how you measure it, has become a nagging headache for astronomers — one that threatens to upend our best understanding of the universe.
But cosmic migraine relief could be on its way in the form of colliding and merging black holes. A new study detailed how the space-time ripples produced by crashing black holes create a hum with a strength that changes depending on how fast the universe is expanding.
However, current detectors will need some upgrades before they can pick up this gravitational wave background with the sensitivity needed. The good news is that cosmologists expect those to come within a few years.

Science Spotlight
Ancient 'alien-like' skulls have been found on every continent but Antarctica. Anthropologists are starting to figure out why.
People around the world and throughout time have practiced head shaping (also called cranial vault modification) on their children. Yet exactly why and how this body-modifying trend took off has remained unclear. That's why staff writer Kristina Killgrove embarked on her own journey to answer the head-scratching mystery in this Science Spotlight.

Vanuatu's 'barefoot volcanologist' stands at ash- and sulfur-spewing Mount Yasur in award-winning photograph
This stunning photo, captured by photographer Elle Leontiev, shows self-taught volcanologist Philip standing by the slopes of Mount Yasur, a 1,184-foot (361 meters) active volcano in Vanuatu.
Philip, who was born and lives at the volcano's base, has spent years studying its moods and cycles with French volcanologist Thomas Boyer. He also has a pair of custom-made boots gifted to him by actor Will Smith, but he prefers walking barefoot on the volcanic terrain.
