Today you can hardly tell when something is remade, because so often it is remade by code. When you press your foot down on your car’s accelerator, for instance, you’re no longer controlling anything directly; there’s no mechanical link from the pedal to the throttle. Instead, you’re issuing a command to a piece of software that decides how much air to give the engine. The car is a computer you can sit inside of. The steering wheel and pedals might as well be keyboard keys.

The Netherlands is a small, densely populated country, with more than 1,300 inhabitants per square mile. It’s bereft of almost every resource long thought to be necessary for large-scale agriculture. Yet it’s the globe’s number two exporter of food as measured by value, second only to the United States, which has 270 times its landmass ... The Dutch are also the world’s top exporter of potatoes and onions and the second largest exporter of vegetables overall in terms of value.

Now, researchers at the University of Cambridge have created a new material that mimics spider silk’s strength, stretchiness and energy-absorbing capacity. This material offers the possibility of improving on products from bike helmets to parachutes to bulletproof jackets to airplane wings. Perhaps its most impressive property? It’s 98 percent water.

The treatment requires removing millions of a patient’s T-cells...and genetically engineering them to kill cancer cells. The technique employs a disabled form of H.I.V....to carry new genetic material into the T-cells to reprogram them. The process turbocharges the T-cells to attack B-cells, a normal part of the immune system that turn malignant in leukemia. The altered T-cells...are then dripped back into the patient’s veins, where they multiply and start fighting the cancer.

A top-of-the-line E5 is the size of a postage stamp, retails for $4,115, and uses about 60 percent more energy per year than a large Whirlpool refrigerator. You use them whenever you search Google, hail an Uber, or let your kids stream Episode 3 of Unbreakable Kimmy Schmidt in your car. These feats of computer science are often attributed to the rise of the smartphone, but the hard work is being done on thousands of servers. And pretty much all of those servers run on Intel chips.

Throughout the world, food waste and spoilage is a significant problem facing supply chains from farm to fork ... The crisis is even more acute across Africa, a continent where the majority of people derive their livelihood from agriculture. Currently, more than 20 million people in northeast Nigeria, South Sudan, and Somalia are facing starvation. Yet, half of all the staple food in the continent is lost in the post-harvest stage or before they hit the market.

Tumors also vary hugely between individuals. Dutch researchers grew organoids from patients with colorectal tumors and identified genetic changes that had occurred in the tumour cells compared to the patient’s healthy tissue. They were then able to see how these altered the way the cells behaved. They tested anti-cancer drugs on the organoids and could tell which drugs did and did not kill the tumor cells.

China...is aware of its creativity deficit. In 2016, Beijing accelerated its Silicon Valley shopping spree, buying tech and talent it couldn’t produce at home. Americans often observe that China is imitative, not innovative, and that its politicized universities and denial of personal freedom make it dependent on others for new ideas. That may have been important before China got rich, but does China’s inability to foster innovation still matter now that it can purchase it overseas?

Asia accounts for more than half of global food waste due to a lack of adequate infrastructure but a technique practiced by early Egyptians could help resolve the modern-day problem ... The bulk of food wasted is at the post-harvest, storage and transport stages, not at the consumption end, they observed, noting that India loses up to 40 percent of fruit and vegetable output because of poor refrigeration.

In other words, plants create themselves partly out of thin air. Salad greens are about ninety per cent water. About half of the remaining ten per cent is carbon ... Aeroponic farming uses about seventy per cent less water than hydroponic farming, which grows plants in water; hydroponic farming uses seventy per cent less water than regular farming. If crops can be raised without soil and with a much reduced weight of water, you can move their beds more easily and stack them high
