Always wanted to help fight climate change? Then join the Earth Hour party on Saturday, March 25 by turning off all lights from 8:30 — 9:30 PM local time. This small action, taken by hundreds of millions of people around the world, will make a dent in our efforts to reverse global warming. More importantly, it will demonstrate what can be achieved if we all unite to protect our planet.

Researchers have long maintained that we sleep to accomplish a neural or physiological function that cannot be completed when awake. Why else would higher animals waste a third of their lives sleeping when they could be doing more important things like looking after their families, working, or hunting? Some scientists believe sleeping helps recharge the body, while others think it is important for consolidating newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day.
As most people age, the crystalline lenses in their eyes start to stiffen and are unable to change shape as easily. As a result, objects in close range start to look blurry, forcing many middle-aged adults to carry reading glasses either around their necks or tucked away in a handbag. Those already suffering from nearsightedness, or myopia, a condition where distant objects appear blurry, have to depend on bifocals or, even worse, switch between two pairs of glasses. However, thanks to some Utah researchers there may finally be a solution — self-adjusting “smart” glasses.
With its wide canopy of leaves, the majestic 50-feet tall manchineel tree that is native to the Caribbean, Florida, the northern coast of South America, Central America, and the Bahamas, looks particularly inviting, especially on a hot summer day. But you may be wise to heed the warning signs given that the deceptively innocuous tree holds the Guinness World Record for “the world’s most dangerous tree.”
If some geologists have their way, world maps will soon be altered to reflect an eighth continent. Dubbed “Zealandia,” the landmass that lies east of Australia covers 1.9 million mi2 (4.9 million km2), or an area larger than the Indian subcontinent. The only catch? Over 94 percent of it is submerged in the southwest Pacific Ocean, with just the islands of New Zealand and New Caledonia, visible above sea level.
The phrase “good things come in small packages” certainly appears to hold true when it comes to ants. The tiny creatures can survive floods by morphing into rafts, find their way home using an internalized GPS system, and even lift up to 20 times their body weight. In 2013, scientists discovered that the insects whose brains are smaller than a quarter of a small pin’s head could even use tools, a skill that was once believed to be the realm of “intelligent” species like humans, and a select number of animals. Now, researchers from the University of Szeged in Hungary have discovered that when given a choice, the clever insects even have the smarts to select the most efficient tool for the job.
Even if math doesn’t rank high on your list of favorite subjects, chances are you still look forward to Pi Day. That’s because though the discussions may begin with Pi — the ratio of the circumference of a circle to its diameter — they invariably end with a piece or two of yummy pie! The event is commemorated on March 14 because though the irrational number (its decimal representation never ends and never repeats) has been calculated to over ten trillion digits, it is widely recognized as 3.14.
In August 2013, billionaire entrepreneur Elon Musk released a 57-page white paper concept for Hyperloop — a supersonic mass transit system between high-traffic cities that lie within short distances. The founder of Tesla Motors and SpaceX envisioned it to be a frictionless system where pods inside low-pressure, vacuum-sealed tubes would transport passengers and cargo at up to 760 miles an hour — approximately the speed of sound. Powered by solar energy, it would be strong enough to withstand extreme weather and earthquakes.
