How heat treatment affects a milk alternative made from rice and coconut water      (via sciencedaily.com) 

Whether they're made from soybeans, almonds, oats, or just sourced straight from the cow, milk products must go through heat treatment to prevent harmful bacterial growth and keep them safe. But understanding how these processes affect new, plant-based milk formulations could make the beverages more pleasant to drink as well. Researchers have discovered how pasteurization and sterilization affects the look and feel of one such drink made from coconut and rice.

When electrons slowly vanish during cooling      (via sciencedaily.com) 

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.

Novel thermal sensor could help drive down the heat      (via sciencedaily.com) 

Excess heat from electronic or mechanical devices is a sign or cause of inefficient performance. In many cases, embedded sensors to monitor the flow of heat could help engineers alter device behavior or designs to improve their efficiency. For the first time, researchers exploit a novel thermoelectric phenomenon to build a thin sensor that can visualize heat flow in real time. The sensor could be built deep inside devices where other kinds of sensors are impractical. It is also quick, cheap and easy to manufacture using well-established methods.

Catalyst can control methane emissions in natural gas engines      (via sciencedaily.com) 

A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the advance in single atom catalysis has the potential to lower exhaust emissions of methane, one of the worst greenhouse gases that traps heat at about 25 times the rate of carbon dioxide. Researchers showed that the single-atom catalyst was able to remove methane from engine exhaust at lower temperatures, less than 350 degrees Celsius (662 degrees Fahrenheit), while maintaining reaction stability at higher temperatures.

Droplet levitation is a new way to explore airborne viruses and microorganisms      (via sciencedaily.com) 

Researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface. Further exploring the effects of various external conditions on self-sustained droplet levitation will reveal whether it can be harnessed and adapted for microbiology and biochemistry applications.
