“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.

The parents were asked to interact with their children as they normally would, and about half of the children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than the parents of girls.

The findings were published in the journal Developmental Science.

【推荐1】Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle —named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t  help if you’re stuck in traffic. The car needs a runway.

Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition  is now going through crash tests to make sure it meets federal safety standards.

Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

【推荐2】New bio-plastics are being made in laboratories from straw, wood chips and food waste, with researchers aiming to replace oil as the source of the world’s plastic.

The new approaches include genetically modifying bacteria to eat wood and produce useful chemicals. But the bio-plastics are currently significantly more expensive to make than fossil fuel-based plastics.

Land and seas around the world, from high mountains to deep oceans, have become polluted with plastic, prompting major public concern. The world has produced 8bn tons of plastic since the 1950s and demand is still rising.

While some waste plastic is recycled, much of it is burnt to produce electricity, resulting in carbon emissions that drive climate change. In contrast to plastic made from oil, plastics made from plant-based materials only release the carbon the plants absorbed from the air as they grew. Bio-plastics will also give more options for products that biodegrade (生物降解) in the environment, although they can be made very long-lasting if required.

“Plastics are an incredible enhancement to our daily lives,” said Paul Mines, CEO of Biome Technologies in the UK, which has spent t5m in the last five years on bio-plastics research. “But we can’t go on using fossil fuel-based materials. About 6-7% of every barrel (桶) of oil is used to make plastics.”

“Using plant materials is feasible,” said professor Simon, at the University of York. “Replacing half of the nation’s plastic bottles could be done using just 3% of the sugar beet crop, 5% of wheat straw or 2.5% of food waste,” he said.

Currently, just a few thousand tons of bio-plastic are used in the UK each year, compared to millions of tons of conventional plastic. Mines said this could rise to about 20,000 tons in the next five years.

【推荐3】New York-based Ecovative has been creating environmentally friendly packaging made from mushrooms and agricultural waste since 2009. Now, the company wants to bring their amazing material into homes and offices with a new line of compostable (可堆肥的) furnishings that are grown using just three materials: mycelium (the vegetative part of mushrooms), hemp (麻类植物), and salt.

While creating hard material from mushrooms might sound magical, the company’s CEO Eben Bayer says it is a relatively low-tech process and compares it to “making bread”. The company begins by adding a few mycelium cells to damp hemp or other agricultural waste.

The mycelium that grows like little hairs is allowed to twist with the waste until everything is “glued” together. The combination is then mixed again and placed into the desired mold (模具) where it continues to grow and harden. The resulting material is then baked in the oven. In addition to making it as strong as wood, the heat also kills the mycelium, thus giving the compostable material a similar shelf life to wood.

Also, though the table tops of the stylish Tafl and King’s tables released at the recently held Biofabricate 2016 conference in New York City resemble marble, they are far from it. The perfectly carved blocks are made of a material grown by a North Carolina-based company named bioMASON using grains of sands and bacteria.

As you have probably guessed, this waste-free furniture does not come cheap. Customers can expect to pay anywhere from $249 USD for the Tafl to $699 USD for the King’s table, both of which are only available in limited quantities. Those that cannot afford those prices can choose cheaper GIY (grow it yourself) ones made of various products ranging from Christmas tree decorations to lamp shades.
