Do measurements produce the reality they show us?      (via sciencedaily.com) 

The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.

Improving urban planning with virtual reality      (via sciencedaily.com) 

What should the city we live in look like? How do structural changes affect the people who move around it? Cartographers use virtual reality tools to explore these questions before a great deal of money is spent on building measures. Using the Unity3 game engine, they recreate scenarios in 3D where people can experience potential changes through immersion. They were able to prove that the physical reaction to this experience is measurable.

Turning old maps into 3D digital models of lost neighborhoods      (via sciencedaily.com)     Original source 

Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic neighborhoods using machine learning and historic Sanborn Fire Insurance maps.

First detection of crucial carbon molecule      (via sciencedaily.com)     Original source 

Scientists detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.

Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts      (via sciencedaily.com)     Original source 

CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.

Biodegradable gel shows promise for cartilage regeneration      (via sciencedaily.com)     Original source 

A gel that combines both stiffness and toughness is a step forward in the bid to create biodegradable implants for joint injuries, according to new research. Mimicking articular cartilage, found in our knee and hip joints, is challenging. This cartilage is key to smooth joint movement, and damage to it can cause pain, reduce function, and lead to arthritis. One potential solution is to implant artificial scaffolds made of proteins that help the cartilage regenerate itself as the scaffold biodegrades. How well the cartilage regenerates is linked to how well a scaffold can mimic the biological properties of cartilage, and to date, researchers have struggled to combine the seemingly incompatible properties of stiffness and toughness. Now, new research outlines a method to marry these properties in a biodegradable gel.
