As coronavirus spreads to countries with medical systems destroyed by war and corruption, citizens are finding innovative ways to help frontline workers. CNN’s Arwa Damon follows people in Afghanistan, Zimbabwe and Syria who have all found ways to build ventilators from recycled parts and with limited funding.

Excellent speech.

Our civilization is made up of countless individuals and pieces of material technology, which come together to form institutions and interdependent systems of logistics, development and production. These institutions and systems then store the knowledge required for their own renewal and growth.

How do you recycle the equivalent of 1,8 million single use plastic bags, and resolve South Africa’s pothole problem? Roll out plastic roads, of course!

That’s exactly what the Kouga Municipality in the Eastern Cape is in the process of doing – and the benefits to road users are manifold.

The concept of a plastic road isn’t a new one. Several years ago, companies in Scotland and the USA pioneered the idea of breaking down plastic waste, and adding it to asphalt. Now, there are thousands of kilometres of plastic roads all over the world, from Australia, the UK and New Zealand to India, Turkey, Slovenia and now South Africa.

Moderna has accelerated its manufacturing capacity for its COVID-19 vaccine candidate mRNA-1273 and additional future products through a 10-year agreement with Lonza announced today by the companies.

The companies agreed to establish manufacturing suites for Moderna at Lonza’s facilities in the U.S. and Switzerland for the production of mRNA-1273. Technology transfer is expected to begin in June, with the first batches of mRNA-1273 set to be manufactured at Lonza’s U.S. site in July.

Moderna and Lonza also said they intend to establish additional production suites across Lonza’s worldwide facilities, ultimately allowing for the manufacture of material equivalent to up to 1 billion doses of mRNA-1273 per year for use worldwide, based on the currently expected dose of 50 mcg.

Carlsberg and Coca-Cola back pioneering project to make ‘all-plant’ drinks bottles.

A laser light shone through the dark could power robotic exploration of the most tantalising locations in our Solar System: the permanently-shadowed craters around the Moon’s poles, believed to be rich in water ice and other valuable materials.

ESA’s Discovery & Preparation programme funded the design of a laser system to keep a rover supplied with power from up to 15 km away while it explores some of these dark craters.

At the highest lunar latitudes, the Sun stays low on the horizon all year round, casting long shadows that keep sunken craters mired in permanent shadow, potentially on a timescale of billions of years. Data from NASA’s Lunar Reconnaissance Orbiter, India’s Chandrayaan-1 and ESA’s SMART-1 orbiters show these ‘permanently shadowed regions’ are rich in hydrogen, strongly suggesting water ice can be found there.

It’s a frustrating fact that whenever you try to improve materials like steel, you end up introducing new weaknesses at the same time. It’s a balancing act between different properties. Now, engineers have developed a new type of “super steel” that defies this trade-off, staying strong while still resisting fractures.

For materials like steel, there are three main properties that need to be balanced – strength, toughness and ductility. The first two might sound like the same thing, but there’s an important difference. Strength describes how much of a load a material can take before it deforms or fails, measured in Pascals of pressure. Toughness, meanwhile, measures how much energy it takes to fracture a material.

For reference, glass has relatively high strength but low toughness, so it’s able to support quite a bit of weight but it doesn’t take much energy to break.

Masks, gowns, and other personal protective equipment (PPE) are essential for protecting healthcare workers. However, the textiles and materials used in such items can absorb and carry viruses and bacteria, inadvertently spreading the disease the wearer sought to contain.

When the coronavirus spread amongst healthcare professionals and left PPE in short supply, finding a way to provide better protection while allowing for the safe reuse of these items became paramount.

Research from the LAMP Lab at the University of Pittsburgh Swanson School of Engineering may have a solution. The lab has created a textile coating that can not only repel liquids like blood and saliva but can also prevent viruses from adhering to the surface. The work was recently published in the journal ACS Applied Materials and Interfaces.
