Mysteriously quiet space baffles researchers

Posted by in categories: cosmology, physics

Astrophysicists have concluded the yet most precise search for the gravitational wave background created by supermassive black hole mergers. But the expected signal isn’t there.

Last month, Lawrence Krauss rumored that the newly updated gravitational wave detector LIGO had seen its first signal. The news spread quickly – and was shot down almost as quickly. The new detector still had to be calibrated, a member of the collaboration explained, and a week later it emerged that the signal was probably a test run.

Your Gut May Be Home to an Entirely New Form of Life

Posted by in categories: genetics, health, life extension

Might be a good start point for some new longevity research.


A new genetic analysis of human gut bacteria is turning up some really weird critters—so weird, in fact, that some biologists are speculating we’ve found an entirely new domain of life. We should take that possibility with a healthy dose of skepticism. But here’s why it’s even being discussed.

In the past ten years, new genomic technologies have, for the first time, enabled scientists to explore our microbiome—that trove of invisible critters that live on us and in us. Microbiome research is quite literally rewriting the textbooks on human biology, as we learn that everything from our mouths to our intestines to our skin is, in fact a complex and diverse ecosystem. Hell, we’re even surrounded in a personal cloud of bacteria. By some estimates, the human cells in your body are vastly outnumbered by microbes.

Iceye — Global monitoring, when it matters

Posted by in categories: innovation, satellites

The ICEYE system is unique because we do not rely on traditional optical imaging technology. Unlike camera technology, our radar is not limited by the same requirements – it’s capable of viewing through cloud cover, bad weather, and darkness, providing unlimited access wherever it’s needed.

The timeliness of the imaging service is always limited by the speed of access to the target site. We’ve applied miniaturization and industrial manufacturing to the field of radar imaging. This allows us to launch not just one, but tens of satellites and ultimately reduce the response times from days to minutes.

“We believe this breakthrough in earth imaging is going to have a real positive impact on the world.”

Scientists develop ‘nanopores’ that inexpensively filter the salt out of seawater

Posted by in categories: energy, engineering, materials

There’s filtration and then there’s filtration. Engineers in the US have been working on the latter, coming up with a new markedly more energy-efficient way of taking the salt out of seawater, which could deliver huge advantages in terms of providing people with access to drinking water and help combat problems like drought.

The researchers have developed a material that allows high volumes of water to pass through extremely tiny holes called ‘nanopores’ while blocking salt and other contaminants. The material they’re using – a nanometre-thick sheet of molybdenum disulphide (MoS2) riddled with these nanopore holes – is the most efficient of a number of thin-film membranes that the engineers modelled, filtering up to 70 percent more water than graphene.

“Even though we have a lot of water on this planet, there is very little that is drinkable,” said Narayana Aluru, a professor of mechanical science and engineering at the University of Illinois and leader of the study. “If we could find a low-cost, efficient way to purify sea water, we would be making good strides in solving the water crisis.”

A five-story vending machine for cars just opened in Nashville

Posted by in category: transportation

Buying a car is a hellish process. The reward for spending hours researching the right one is a trip to a local dealership — an experience that assaults the nerves in such a way that it’s only rivaled by appointments with the dentist. But what if buying a car was easier than that? What if it was as easy as, say, a vending machine?

A few years ago, a company called Carvana followed in the footsteps of companies like CarMax by trying to move the car buying experience completely online. The process of purchasing a car on Carvana’s website includes all the steps that normally take place at a dealership: getting approved for and selecting financing, selecting a warranty, and signing the contract. It’s a process that, in an interview with The Verge, Carvana CEO Ernie Garcia is quick to point out takes many Carvana customers 20 minutes or less.

This left customers with just one dealership interaction: choosing pickup or delivery. And Garcia says that, more often than not, Carvana customers were choosing pickup — so much so that a subsequent pickup store in Atlanta was a rousing success. Now, though, Carvana is adding some spice to that experience.
