What will people wear in the future? | The Economist

Innovation in fashion is sparking radical change. In the future clothes could be computers, made with materials designed and grown in a lab.

A new wave of innovation is fueling a radical change in fashion. Wearable technology, data, automation and lab-grown materials will have a major impact on what people will be wearing in the future.

Since the birth of sewing and weaving, technology has always led developments in fashion. The Industrial Revolution mechanized manufacturing enabling mass production. In the 1960s synthetic materials like polyester took off, creating new possibilities for fashion.

Now the convergence of new technologies is opening up previously unimaginable possibilities. Self-styled fashion scientist Dr Amanda Parkes is in the vanguard of the industry’s latest reinvention. She heads up innovation at FT labs, a venture capital firm that invests primarily in disruptive fashion tech startups. Among these startups the race is on to find the next generation of renewable materials that can be grown in a lab. Traditional silk is produced from insect larvae that form cocoons, most commonly silkworms. But rather than relying on these insects bolt threads is creating silk in test tubes. Bio fabricated materials remove the need for animals and insects and they are a more sustainable and efficient way of producing raw materials.

Other companies are creating leather alternatives. Rather than using animals scientists are creating bio fabricated materials from pineapple leaves and even mushrooms. The convergence of fashion and technology also provides opportunities to transform not just clothes but the people wearing them.

Denmark Is Building Nine Gigantic Artificial Islands

Authorities in Denmark plan to build nine artificial islands off the coast of Copenhagen with a total area of more than 32 million square feet (3 million square meters.) The hope is that the new islands, which will be called “Holmene,” will become a futuristic hub for sustainable business and commerce.

“I think this could become a sort of European Silicon Valley,” said Brian Mikkelsen, the head of the Danish chamber of commerce, in an interview with The Guardian.

Project to Eradicate Termites Reveals How Much Rainforests Need Them

Homeowners tend to equate termites with property value apocalypse, but ecologically speaking, they’re more a force of stability than destruction. A new study points to how termites can help the rainforests they call home to weather droughts—which are expected to increase in frequency and intensity as climate change causes the tropics to heat up.

Termites are found across the tropics, where they feed on wood and dead leaves and build mounds that can sometimes be seen from space. Despite the wide-ranging influence of these ecological engineers, there’s been little research on how termites impact the ability of the forests they call home to withstand one of the biggest natural disturbances they face: drought.

‘Flipped’ metal oxide cage can sort CO2 from CO

How do you separate carbon dioxide from carbon monoxide? One way, showcased by a new study from Kanazawa University, is to use a bowl of vanadium. More precisely, a hollow, spherical cluster of vanadate molecules can discriminate between CO and CO 2, allowing potential uses in CO 2 storage and capture.

At the molecular scale, small objects can fit inside larger ones, just like in the everyday world. The resulting arrangements, known as host-guest interactions, are stabilized by non-covalent forces like electrostatics and hydrogen bonds. Each host will happily take in certain molecules, while shutting out others, depending on the size of its entrance and how much interior space it can offer the guest.

Anion structures of CH 2 Cl 2 (guest)-inserted V12 (left) and guest-free V12 are shown. Orange and red square pyramids represent VO 5 units with their bases directed to the center of the bowl, and the inverted VO 5 unit. Green and black spheres represent Cl and C, respectively. Hydrogen atoms of CH 2 Cl 2 are omitted for clarity. (Image: Kanazawa University)

Why the Future of Solar Power Is from Space

Over seven decades ago in 1941, Isaac Asimov wrote a short story, “Reason” (PDF), in which energy captured from the sun was transmitted via microwave beams to nearby planets from a space station. Flash forward to today, scientists are looking to make that very science fiction dream a reality for Earth.

There has been tremendous research on space-based solar power (SBSP) or space solar power (SSP) since the mid 20th century. Here is a great timeline of the various international studies and projects related to SBSP.

With SBSP, we could solve our energy and greenhouse gas emission problems with little environmental impact. Professor Sergio Pellegrino of CalTech recently said an SBSP system would receive eight times more energy than Earth does. With SBSP’s continuous massive energy output capability and the fact that our sun is slated to exist for another 10 billion years, we can safely assume we will not run out of this energy source anytime soon.

Scientists have combined a house plant with a rabbit gene. This is why

Scientists at the University of Washington (UW) may have found an unexpected way to tackle persistent indoor air pollution: a common houseplant modified with rabbit DNA.

Researchers wanted to find a way to remove the toxic compounds chloroform and benzene from the home, a UW press release explained. Chloroform enters the air through chlorinated water and benzene comes from gasoline and enters the home through showers, the boiling of hot water and fumes from cars or other vehicles stored in garages attached to the home. Both have been linked to cancer, but not much has been done to try and remove them. Until now.

“People haven’t really been talking about these hazardous organic compounds in homes, and I think that’s because we couldn’t do anything about them,” senior study author and UW civil and environmental engineering department research professor Stuart Strand said in the release. “Now we’ve engineered houseplants to remove these pollutants for us.”
