Craft brewers are continuously upping the ante and coming up with innovative ways to make or flavor their newest beers. Now, researchers are adding a new twist of their own, speeding up the brewing process with beer-making mini-robots or 'BeerBots.' The team shows that these self-propelled, magnetic packages of yeast can make the fermentation phase go faster and cut out the need to filter the beverage.

An interdisciplinary team of researchers has developed a suite of tools to estimate the total economic value of improving water quality in urban streams. The work can assist federal and state agencies charged with developing environmental regulations affecting urban ecosystems across the Piedmont Region of the United States, which stretches from Maryland to Alabama.

Researchers have developed a novel and highly efficient method for rapid antibiotic susceptibility testing using optical microscopy. The technique, called Optical Nanomotion Detection, is extremely rapid, single-cell sensitive, label-free, and requires only a basic traditional optical microscope, equipped with a camera or a mobile phone.

Organic solar cells have a photoactive layer that is made from polymers and small molecules. The cells are very thin, can be flexible, and are easy to make. However, the efficiency of these cells is still much below that of conventional silicon-based ones. Applied physicists have now fabricated an organic solar cell with an efficiency of over 17 percent, which is in the top range for this type of material. It has the advantage of using an unusual device structure that is produced using a scalable technique.

The adage 'birds of a feather flock together' is being given new meaning in a recent study. When multiple species join a single flock, they appear to mimic each other, with spectacular results. Researchers think this counterintuitively promotes diversity.

Researchers have designed a tabletop-sized vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day and deployed anywhere vaccines are needed. The vaccine doses are contained within microneedle patches that can be stored long-term at room temperature and applied to the skin, avoiding the need for injections.

A research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it. A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around newly formed stars. The newly published findings represent a first step toward using machine learning to identify previously overlooked exoplanets.

Why does it feel so difficult to shout upwind? The sensation is common enough to have found its way into an idiom about not being understood. Researchers wanted a scientific explanation for the phenomenon -- and there wasn't been one. They have now shown that our common sense understanding of this situation is wrong. It isn't harder to shout into the wind; it's just harder to hear yourself.

The ionosphere -- the region of geospace spanning from 60 to 1000 kilometers above the Earth -- impairs the propagation of radio signals from global navigation satellite systems (GNSS) with its electrically charged particles. This is a problem for the ever higher precision required by these systems -- both in research and for applications such as autonomous driving or precise orbit determination of satellites. Models of the ionosphere and its uneven, dynamic charge distribution can help correct the signals for ionospheric delays, which are one of the main error sources in GNSS applications. Researchers have presented a new model of the ionosphere, developed on the basis of neural networks and satellite measurement data from 19 years. In particular, it can reconstruct the topside ionosphere, the upper, electron-rich part of the ionosphere much more precisely than before. It is thus also an important basis for progress in ionospheric research, with applications in studies on the propagation of electromagnetic waves or for the analysis of certain space weather events, for example.

A new age of superconductors may be about to beginn: In the 1980s, many superconducting materials (called cuprates) were based on copper. Then, nickelates were discovered -- a new kind of superconducting materials based on nickel. But now, scientists from Austria and Japan have shown: There is a 'Goldilocks zone' of superconductivity which can neither be reached with cuprates nor with nickelates. Instead, palladium-based materials ('palladates') could be the solution.
