Over at Discovery News, Emily Sohn asks the question I've been wondering for the last two weeks. Why are Olympians today better at their sports than Olympians of the past? Why do speed records keep getting broken? Why can gymnasts do more elaborate routines?
I mean, I have plenty of reasonable, speculative answers for those questions. But I hadn't seen them addressed in a factual way. This is great. And fascinating.
The answer, experts say, involves a combination of incremental technological improvements, as well as a growing population of people attempting a larger variety of sports that they start earlier and stick with longer. The mind plays a big role, too, especially when it comes to toppling seemingly insurmountable barriers, like the four-minute mile of the past or the two-hour marathon of the future.
"There is almost certainly a species limit in terms of physical capabilities, and I suspect we might be in the range of that," said Carl Foster, an exercise physiologist at the University of Wisconsin, Lacrosse. "But every time scientists say humans are not going to go any faster, they've been shown to be wrong. You can take that one to the bank."
Through calculations of maximum power output, oxygen use, heart function and other factors, some researchers have attempted to predict what the absolute limits of human ability will be. Much-debated estimates include 1:58 for the marathon (a five-minute improvement over the current men's record of 2:03.38), and 9.48 for the men's 100m.

The deadly 2013 El Reno tornado was 2.5 miles (4 km) wide and killed a team of tornado experts. But as Anton Seimon explains, his colleagues turned that tragedy into an opportunity to confirm a key element of tornado formation.
Some snakes have evolved the ability to glide through the air. For example, paradise tree snakes in southeastern Asia can launch off from a branch and fly as far as 10 meters. Scientists have known that the snakes flatten their bodies to gain lift but new research reveals that they also undulate their bodies as […]
We humans are castaways on an ocean of uncertainty. Since the beginnings of history, our ancestors sought knowledge and understanding about their lives, their relationship with the cosmos, and perhaps take a peek into their future. In such effort—long before the answers of science—earthlings developed a rich variety of divination practices and systems. Many forms […]
This is truly a golden age for fans of a big ginormous TV screen. Not too long ago, to buy a television over 40 inches usually meant wheeling one of those massive Mitsubishi or Toshiba projection monoliths into your home, consuming a vast portion of any room at a cost of potentially $7,000 to $8,000. […]
Nearly 30 years after it started its run as the most dominant productivity software ever created, the Microsoft Office suite of programs are now virtually synonymous with personal computing. From its days bundled with Windows to its current life as Office 365 cloud-based apps, there’s no reason to think perennial hits like Word, Excel and […]
