Bizz Buzzlaunched today as Australia’s only group buying site dedicated to small business deals. While Australia has seen manyGrouponcopycats, and Groupon itself owns a separately-branded service in Australia, none of them aim straight for small business. As an example, Bizz Buzz’s introductory coupon offers 60 days of access toShoeboxed.com.au, a service that takes care of data entry and categorization for receipts, for free. Entrepreneur Marcus Layton founded Bizz Buzz when he saw a gap in the market despite everyone jumping on the Groupon craze....

Bizzabo is an Israel-based startup founded by Eran Ben-Shushan, Alon Alroy and Boaz Katz, all alumni of theSam Zell Entrepreneurship Program....

Black holes at the center of 2020 Nobel Prize in physics — astrophysicist explains why it’s a big deal Dying stars form black holes Sir Roger Penrosewon half the prize for his seminal work in 1965 which proved, using a series of mathematical arguments, that under very general conditions, collapsing matter would trigger the formation of a black hole. This rigorous result opened up the possibility that the astrophysical process of gravitational collapse, which occurs when a star runs out of its nuclear fuel, would lead to the formation of black holes in nature....

It tookAlbert Einstein 10 years to find the equations of general relativity, butGerman astrophysicist Karl Schwarzschild only needed a few months to solve them. Schwarzschild’s solution describes the gravity of an isolated, spherical and unchanging object — the enigmatic black hole — but it was not understood for many years. Black holes helped to explain new astronomical discoveries, becoming essential ingredients of astrophysics. Science regardedblack holes as abstractions until the 1960s....

“There’s nothing quite like it. A double-shot of Black Magic contains about as much caffeine as three Red Bulls,” said the woman behind the counter as I handed over $45 for a large 1kg bag of beans. “Don’t give it to anyone with a pacemaker.” “Unless I don’t like them,” I joked, and had the staff at the Mount Tamborine Coffee Plantation not been the nicest people that side of a counter you’ll meet, I imagine it would’ve gone down as badly as I’d expected....
