If there is to be a "6G Wireless," its proponents will need to learn some significant lessons from the era of 5G. Already, 5G Wireless as a market strategy is four years old. The R&D divisions of telecommunications firms whose 5G rollouts are well under way, are now looking ahead to whatever the next version of wireless may be. . . or, at least, they're trying to. So far, what they're seeing may be a bit far out. executive guide What is 5G? Everything you need to know about the new wireless revolution It's a capital improvement project the size of the entire planet, replacing one wireless architecture created this century with another one that aims to lower energy consumption and maintenance costs.

At the mercy of natural selection since the dawn of life, our ancestors adapted, mated and died, passing on tiny genetic mutations that eventually made humans what we are today. But evolution isn't bound strictly to genes anymore, a new study suggests. Instead, human culture may be driving evolution faster than genetic mutations can work. In this conception, evolution no longer requires genetic mutations that confer a survival advantage being passed on and becoming widespread. Instead, learned behaviors passed on through culture are the "mutations" that provide survival advantages. This so-called cultural evolution may now shape humanity's fate more strongly than natural selection, the researchers argue. "When a virus attacks a species, it typically becomes immune to that virus through genetic evolution," study co-author Zach Wood, a postdoctoral researcher in the School of Biology and Ecology at the University of Maine, told Live Science. Such evolution works slowly, … [Read more...] about Humans might be making genetic evolution obsolete
The most oft-quoted average rate of human hair growth is 6 inches (15 centimeters) per year. However, the majority of studies measuring the rate of hair growth didn't take into account the race of study participants. It's known, for instance, that Caucasian hair differs from Asian and African hair in several ways, e.g., density (how closely hair strands are packed together) and the angle of hair growth. A 2005 study in the journal International Journal of Dermatology also found a difference among races in the rate of hair growth. For example, Asian hair grows the fastest, while African hair grows the slowest. Related: Fur, wool, hair: What's the difference? The average hair growth rate of Asian female participants was nearly 6 inches per year. Comparatively, African female participants' hair grew 4 inches (10 cm) per year, while Caucasian female participants' hair grew a little more than 5 inches (13 cm) per year. The hair growth rate of the male participants … [Read more...] about How fast does hair grow?
What just happened? Elon Musk has faced criticism recently over tweets that send Bitcoin crashing, but he can push the price upwards, too. On Sunday, the CEO said that Tesla would resume accepting the crypto once there is confirmation of reasonable clean energy use by miners. Tesla invested $1.5 billion in Bitcoin earlier this year and announced it would accept the digital currency as payment for its products, pushing the price to $44,000. In April, BTC reached a record high of almost $65,000. Tesla's love affair with BTC turned sour last month when Musk reversed the decision to accept the coin as payment for Teslas, citing the environmental impact of mining. That sent Bitcoin's price falling , as did the billionaire's suggestion that Tesla had sold or could sell its holdings. Musk later confirmed his company still holds most of its Bitcoin investment, but the damage had been done. Bitcoin's price over the last week One person having so much influence over the … [Read more...] about Bitcoin surges after Musk says Tesla will resume accepting it when miners use more clean energy
The UK’s competition regulator, the Competition and Markets Authority (CMA), will collaborate with Google as it attempts to rework online ad targeting, the regulator and Google have announced. It comes as Google is attempting to phase out the use of third-party cookies for tracking and targeting users with ads and instead use a new set of technologies it’s calling Privacy Sandbox. In its announcement , Google said this is the first time regulators and technology companies have worked together on new technologies like this. As well as the CMA, the UK’s data protection regulator (the Information Commissioner’s Office, or ICO) will also be involved. “The CMA is taking a leading role in setting out how we can work with the most powerful tech firms to shape their behaviour and protect competition to the benefit of consumers,” the CMA’s chief executive Andrea Coscelli, said in a statement. The collaboration comes in response to the CMA’s announcement in January that it would … [Read more...] about Google to work with UK regulators on its big ad-tracking shakeup
