From raindrops rolling off the waxy surface of a waterlily leaf to the efficiency of desalination membranes, interactions between water molecules and water-repellent “hydrophobic” surfaces are all around us. The interplay becomes even more intriguing when a thin water layer becomes sandwiched between two hydrophobic surfaces, KAUST researchers have shown.

In the early 1980s, researchers first noted an unexpected effect when two hydrophobic surfaces were slowly brought together in water. “At some point, the two surfaces would suddenly jump into contact—like two magnets being brought together,” says Himanshu Mishra from KAUST’s Water Desalination and Reuse Center. Mishra’s lab investigates water at all length scales, from reducing water consumption in agriculture, to the properties of individual water molecules.

Researchers were unable to explain the phenomenon at the molecular level, so in 2016, Mishra organized a KAUST conference on the subject. “We brought together leaders in the field—experimentalists and theorists—leading to intense debates on the understanding of hydrophobic surface forces,” he says.

According to a decade-long study by an international team of researchers, human CO₂ emissions total 100 times more than the planet-warming effects of all volcanoes combined.

The total amount emitted by volcanoes is only about 0.3 gigatons a year — a tiny fraction of the 37 gigatons humankind produced in 2018 alone.

That means they’re not nearly as big of a contributor to global emissions as some prevailing theories hold.

After a year of working with the Federal Aviation Administration, United Parcel Service was awarded a certification that allows it to use drones on medical campuses.

After committing to having a first crewed launch of its rocket ship in 2019, Blue Origin, the rocket manufacturer and launch services company backed by Jeff Bezos, is likely going to have to push that timeline back to 2020.

Speaking onstage at TechCrunch Disrupt San Francisco, Blue Origin chief executive Bob Smith said that the window for getting the crewed flight done within the 2019 time frame was narrowing. “We’re not going to be date-driven,” Smith said.

But as commercial launches come to market, customers can expect to pay “hundreds of thousands of dollars” for a ticket on the New Shepard suborbital flight.

Cooperation means that one individual pays a cost for another to receive a benefit. Cooperation can be at variance with natural selection: Why should you help a competitor? Yet cooperation is abundant in nature and is an important component of evolutionary innovation. Cooperation can be seen as the master architect of evolution and as the third fundamental principle of evolution beside mutation and selection. I will present mathematical principles of cooperation.

Topological insulators are quantum materials, which, due to their exotic electronic structure, on surfaces and edges conduct electric current like metal, while acting as an insulator in bulk. Scientists from the Max-Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) have demonstrated for the first time how to tell apart topological materials from their regular—trivial—counterparts within a millionth of a billionth of a second by probing it with ultra-fast laser light. Their method could open the way for such materials to be used as logic elements in light-controlled electronics able to process information tens of thousands times faster as currently possible. Their study appeared in Nature Photonics.

The most common illustration of the topology concept involves an elastic pretzel, which can be stretched, bent, or twisted in any way; no matter the deformation, it is impossible to make a bagel out of a pretzel or add holes to it, without tearing it apart. The number of holes in a pretzel is thus invariant and provides topological information about the pretzel shape.

In a solid material, quantum-mechanical laws restrict which energies electrons can have, leading to the formation of bands with either allowed or forbidden energies. Using the concept of topology, physicists can describe complex shapes of allowed energy bands and assign them a specific topological number. A special topology of the band structure in a material system manifests itself in exotic properties that can be observed—such as the surface conductivity in topological insulators.

The robot can move its eyes, eyebrows, lips and “other muscles,” the company said.

Today, we have launched the MitoMouse project on our fundraising platform Lifespan.io. This project aims to reverse the damage that aging does to the mitochondrial DNA and to restore energy production in our cells with the goal of preventing age-related ill health.

The next major iteration will be coming from BBC later this year, produced as a serial. The BBC just dropped a new trailer for it, which you can view in all its glory here:
