Searching in vein: a history of artificial blood


Health

For centuries scientists have sought an artificial substitute for blood. Equipped with modern nanotechnology and a humbler strategy, bioengineers think they’re closer than ever.

Since the early 1600s, physicians have unsuccessfully pursued a suitable substitute for the life-giving elixir of blood. We’ve come a long way, but the modern demand for…

The best air conditioner

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic...

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs? ...

Scientists clone monkeys for the first time

Image
Ever since cloning produced Dolly the sheep , scientists have copied a slew of mammals ranging from dogs to ponies. Primates, however, have been elusive -- until now. Chinese researchers have successfully cloned a macaque monkey fetus twice, producing sister monkeys Hua Hua and Zhong Zhong using the same basic method used to create Dolly. The team removed the nucleus from monkey eggs and replaced it with DNA from the fetus, implanting the resulting eggs in female monkeys for them to give birth. The process wasn't easy. It took 127 eggs and 79 embryos to get these results, and it still required a fetus to work (Dolly was cloned from an adult). Still, it reflects progress in cloning science. The team managed the feat by injecting both a form of mRNA and an inhibitor, the combination of which improved the development of blastocysts (the structures that form the embryo) and the pregnancy rate for transplanted embryos. Both baby macaques are healthy, the researchers said, and genet...
