Fur, Feathers, Hair, and Scales May Have the Same Ancient Origin

New research shows that the processes involved in hair, fur, and feather growth are remarkably similar to the way scales grow on fish—a finding that points to a single, ancient origin of these protective coverings.

First 3D colour X-ray of a human using CERN technology

What if, instead of a black and white X-ray picture, a doctor of a cancer patient had access to colour images identifying the tissues being scanned? This colour X-ray imaging technique could produce clearer and more accurate pictures and help doctors give their patients more accurate diagnoses. This is now a reality, thanks to a Read more about First 3D colour X-ray of a human using CERN technology[…]

Humans Didn’t Evolve From a Single Ancestral Population

In the 1980s, scientists learned that all humans living today are descended from a woman, dubbed “Mitochondrial Eve,” who lived in Africa between 150,000 to 200,000 years ago. This discovery, along with other evidence, suggested humans evolved from a single ancestral population—an interpretation that is not standing the test of time. The story of human Read more about Humans Didn’t Evolve From a Single Ancestral Population[…]

Versius Robot allows keyhole surgery to be performed with 1/2 hour training instead of 80 sessions

It is the most exacting of surgical skills: tying a knot deep inside a patient’s abdomen, pivoting long graspers through keyhole incisions with no direct view of the thread. Trainee surgeons typically require 60 to 80 hours of practice, but in a mock-up operating theatre outside Cambridge, a non-medic with just a few hours of Read more about Versius Robot allows keyhole surgery to be performed with 1/2 hour training instead of 80 sessions[…]

Open plan offices flop – you talk less, IM more, if forced to flee a cubicle

Open plan offices don’t deliver their promised benefits of more face-to-face collaboration and instead make us misanthropic recluses and more likely to use electronic communications tools.

Stanford brainiacs say they can predict Reddit raids

A study [PDF] based on observations from 36,000 subreddit communities has found that online dust-ups can be predicted, and the people most likely to cause them can be identified. “Our analysis revealed a number of important trends related to conflict on Reddit, with general implications for intercommunity conflict on the web.” Among the takeaways were Read more about Stanford brainiacs say they can predict Reddit raids[…]

If you’re so smart, why aren’t you rich? Turns out it’s just chance.

Why hiring the ‘best’ people produces the least creative results

Yet the fallacy of meritocracy persists. Corporations, non-profits, governments, universities and even preschools test, score and hire the ‘best’. This all but guarantees not creating the best team. Ranking people by common criteria produces homogeneity. And when biases creep in, it results in people who look like those making the decisions. That’s not likely to Read more about Why hiring the ‘best’ people produces the least creative results[…]

Why People Dislike Really Smart Leaders

Intelligence makes for better leaders—from undergraduates to executives to presidents—according to multiple studies. It certainly makes sense that handling a market shift or legislative logjam requires cognitive oomph.
