After college kids who have three too many all-you-can-drink mimosas and activists who believe Mother’s Day brunches are the best places to take a stand about animal rights, nothing ruins breakfast like spoiled milk. Researchers at the University of California, Berkeley and the National Chiao Tung University in Taiwan feel your pain — so they’re developing 3-D “smart caps” to sense bacterial levels in containers (specifically with milk and juices in mind).

By incorporating microelectrical components into the caps, the devices can measure “capacitance changes of the liquid food due to its deterioration over time,” the researchers wrote in a recent study in Microsystems & Nanoengineering. It’s a little more reliable and less potentially pungent than the ol’ sniff-to-see-if-this-is-still-OK test.

Even if you’re lactose intolerant, the device could change the way you consume food. The researchers say that the innovation could have broader applications beyond milk, by, for example, checking the app while you’re in the grocery store for food on the shelves. Drink up.

SpaceX is gearing up to send humans into space for the first time. On Monday, CEO Elon Musk confirmed a report that claimed NASA estimates the firm will be ready for people-carrying space adventures as early as April of next year. While a good sign for the company’s Mars mission, a successful human test flight would also enable a new method of sending people to the International Space Station.

Thousands of years ago, humans in Eurasia were cut off from the Americas by ice. But when the ice began to melt and humans crossed the Bering Strait from Siberia, the fate of humanity changed, and the Americas were transformed. Still, one major problem at the heart of this great migration has the scientists involved in a new Science Advances study locked in a stalemate. Who got there first, and how did they get there?

Conspiracy theorists of Brisbane caught a glimpse of the unexplainable on Tuesday morning when a mysterious hole opened up in the cotton-ball clouds blanketing the city. Australian Twitter responded predictably, calling the hole a “portal” for UFOs. There’s no denying that the oblong gap seemed wide enough for aliens to step through, but as atmospheric scientist David A. Kristovich, Ph.D., explains to Inverse, it merely marks the footprint of falling ice.

In modern society, you can be lazy and not face much consequence. Don’t want to cook? Order Seamless. Don’t want to move? Call a Lyft. But according to a controversial new study, the same could not be said for Homo erectus, an ancient relative of our species. In the study, scientists claim that H. erectus went extinct because it existed in a constant state of meh.

In recent years, we’ve learned that sea level rise will put coastal cities at risk of greater flooding due to storm surges and at risk of flooding without storms. But new research suggests that sea level rise could also increase the danger of tsunami hazards in those cities, even if they were typically immune from the catastrophic waves in the past. One of these cities is Macau, the Las Vegas of Asia, which stands to lose its world-renowned luxury hotels and casinos if climate change continues at its current pace.
