At 100 years old, the world’s oldest billionaire would be forgiven for taking it easy and enjoying the riches of his eight-decade career.

But for Chang Yun Chung, founder of Pacific International Lines (PIL), staying at home isn’t an option. Despite handing over the role of executive chairman to his son, Teo Siong Seng, earlier this year, the centenarian Singaporean insists on going into the office every day.

“It’s my habit,” Chang told CNBC in a recent episode of “Managing Asia.”

Biology student Mattia Menchetti performed an experiment on a colony of European paper wasps which yielded some very colorful results. Paper wasps are known for their water-resistant nests constructed out of fibers of dead wood and plant stems which have been chewed into a pulp and mixed with saliva. Menchetti provided a captive colony of these wasps with colored paper and in a beautiful display of entomological artwork, the insects produced a vibrant, rainbow nest.

Menchetti began by giving the wasps bits of yellow paper, and slowly introduced more and more multicolored sheets. The colony happily made use of the material to construct a sturdy, technicolor home to house their larvae. Paper wasps are some of the most common wasp species, typically seen in backyards around North America. They tend to establish a single nest across multiple seasons and generations; for this reason, their homes must be incredibly durable. A protein found in the saliva of these wasps is actually so effective at waterproofing their nests that it has been used by scientists to construct a biodegradable drone.

Menchetti has performed a variety of scientific studies about insects, mammals, and the ecology of alien species, which he explains in further detail on his website.

A DNA “knot” breaks several rules thought hard and fast. Now the race is on to understand it. Elizabeth Finkel reports.

The story behind the writing of Frankenstein is famous. In 1816, Mary Shelley and Percy Bysshe Shelley, summering near Lake Geneva in Switzerland, were challenged by Lord Byron to take part in a competition to write a frightening tale. Mary, only 18 years old, later had a waking dream of sorts where she imagined the premise of her book:

When I placed my head on my pillow, I did not sleep, nor could I be said to think. My imagination, unbidden, possessed and guided me, gifting the successive images that arose in my mind with a vividness far beyond the usual bounds of reverie. I saw — with shut eyes, but acute mental vision, — I saw the pale student of unhallowed arts kneeling beside the thing he had put together. I saw the hideous phantasm of a man stretched out, and then, on the working of some powerful engine, show signs of life, and stir with an uneasy, half vital motion.

This became the kernel of Frankenstein; or, The Modern Prometheus, the novel first published in London in 1818, with only 500 copies put in circulation.

Diamond computer chips running at 100-GHz have been demonstrated by Akhan Semiconductor. They are currently using design rules in the 100s of nanometers.

Developers are focusing on power applications on 12-inch wafers. They hope to drive down the costs of production with higher volumes. Power devices are moving into pilot production at a fab. They are using the fab-lite model—that is produce small- to medium-sized runs themselves. They will then transfer their process to foundries when they ramp up into volume production.

Scientists at Newcastle University have discovered neurons in insect brains that compute 3D distance and direction. Understanding these could help vision in robots.

Could a Mediterranean diet and exercise reduce dementia risk?

Researchers at Newcastle University are launching a new study to see whether eating a Mediterranean-style diet and being more physically active could improve brain function and reduce dementia risk.

Phase transitions occur when a substance changes from a solid, liquid or gaseous state to a different state—like ice melting or vapor condensing. During these phase transitions, there is a point at which the system can display properties of both states of matter simultaneously. A similar effect occurs when normal metals transition into superconductors—characteristics fluctuate and properties expected to belong to one state carry into the other.

Scientists at Harvard have developed a bismuth-based, two-dimensional superconductor that is only one nanometer thick. By studying fluctuations in this ultra-thin material as it transitions into superconductivity, the scientists gained insight into the processes that drive superconductivity more generally. Because they can carry electric currents with near-zero resistance, as they are improved, superconducting materials will have applications in virtually any technology that uses electricity.

The Harvard scientists used the new technology to experimentally confirm a 23-year-old theory of superconductors developed by scientist Valerii Vinokur from the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

There’s egg on your face, literally. You tried to juggle some eggs, it all went wrong, and now you’ve got to shower and change your clothes.

Wouldn’t it be faster to just un-break the egg? Breaking it only took a few seconds, so why not do that again, but in reverse? Just reassemble the shell and throw the yolk and the white back inside. You’d have a clean face, clean clothes, and no yolk in your hair, like nothing ever happened.

Why don’t things happen in reverse all the time?

Every now and again, our radio telescopes capture a mystery. A single flash, as powerful in radio wavelengths as half-a-billion Suns, condensed into a burst that lasts just a few milliseconds at most. Now, for the very first time, astrophysicists have traced one of these one-off fast radio bursts (FRBs) to its source.

“This is the big breakthrough that the field has been waiting for since astronomers discovered fast radio bursts in 2007,” said astro-engineer Keith Bannister of Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO).

The signal has been named FRB 180924 — they’re named for the date of detection — and it originated in the outskirts of a Milky Way-sized galaxy roughly 3.6 billion light-years from Earth.
