This week, the first-ever footage of the lethal (to great white sharks) hunting behaviors of Orca pods, SpinLaunch slingshots NASA tech into the sky, and we ask if Kelly Clarkson had a point when she sang “what doesn’t kill you makes you stronger”.

Watch World-First Footage Of Orcas Making A Snack Out Of Great White Sharks

Earlier this year, researchers in South Africa filmed killer whales hunting great white sharks for the first time, and footage of the chase reveals that more orcas are involved than previously thought. The gnarly video shows five killer whales getting in on the act, leading scientists to suspect that the behavior may be spreading through cultural transmission. Read the full story here.


Discovery Of New Route For Human Evolution Affects One In 4,000 Babies

Now, research has discovered a new route through which human evolution can occur in the way that genetic material from our mitochondria can enter the genome. Read the full story here.

Watch SpinLaunch's Giant Slingshot Fling A NASA Payload Into The Sky

US-based startup SpinLaunch has teamed up with NASA to see whether slingshotting objects into the sky could be a viable alternative to chemical-powered rocket launches, and you can watch their latest test right here. Read the full story here.

Not only are they visually stunning, but this collaboration has also spotlighted some new astronomical features that haven't been appreciated before. Read the full story here.

Feature of the week:
