Oil spill-absorbing material inspired by cactus needles

When an oil spill occurs at sea, there are already a number of possible options for gathering the oil that floats in a layer on the water’s surface. Some of the oil also forms into tiny suspended droplets, however, which have proven much more difficult to gather. Now, Chinese scientists have developed what could be a solution – and it owes a debt to the humble cactus needle. Read More

First public tasting of US$330,000 lab-grown burger

If Professor Mark Post of Maastricht University ever opens a burger bar, you might want to take a close look at the prices before you order. On Monday, at a press conference in London, a burger made by Post and his team was served that cost a cool €250,000 (about US$330,000). The reason? The beef that went into making it never saw a pasture and the people in the white coats who handed it to the chef weren't butchers, but bioengineers. Read More

DIFIS funnels up oil spills

When ships sink, as well as the loss of property (and very possibly life), there’s the danger of environmental damage. An oil tanker breaking up is a disaster, but even a cargo ship going down can mean oil leaking from fuel bunkers. Double Inverted Funnel for Intervention on Shipwrecks (DIFIS) is an EU project coordinated by Maritime Research Institute Netherlands (MARIN) that uses a passive system to catch oil as it leaks out of a wreck on the ocean floor.Read More

L'Uritonnoir puts festival-goers' urine to good use

Festivals can be great fun, but aren't always so friendly to the local environment. Gathering that many people in one place tends to produce a large amount of waste, but it's the human waste that can be the hardest to dispose of cleanly. That's why French design group Faltazi has produced L'Uritonnoir, a portable, composting urinal for large festivals that helps to turn a bale of hay into usable fertilizer.Read More

Recyclable solar cells created using trees

Researchers at Georgia Institute of Technology and Purdue University have developed new solar cells based on natural substances derived from plants, including trees. The organic solar cells have an efficiency of 2.7 percent – a new high for cells on substrates derived from renewable raw materials – and can be easily recycled. Read More

Wastewater treatment process may keep fish off antidepressants

While some people may wonder about the possible side-effects of antidepressants on the people who are taking them, here’s another thing to consider ... what happens when the residue from those drugs passes through the user’s urine and into the sewage system? As it turns out, it can enter local waterways and affect the fish. Now, researchers from KTH Royal Institute of Technology in Stockholm have developed technology to keep that from happening.

Recycled plastic waste to fuel Sydney to London Cessna flight

British pilot Jeremy Rowsell is set to fly solo from Sydney to London in a Cessna 182 aircraft powered solely by diesel derived from "end-of-life" plastic (ELP) waste. If all goes to plan, the endeavor will set a new record time for the journey in a single-engine piston plane, and represent a compelling argument for the viability of ELP as a fuel source. Read More
