Scientists develop creepy insect-like robot that can jump on water

As many a first-year chemistry student knows, walking on water isn’t actually physically impossible; chemistry teachers often use water strider insects as an example when teaching students about the surface tension of water molecules.

Here’s why scientists haven’t invented an impossible space engine – despite what you may have read

What if I told you that recent experiments have revealed a revolutionary new method of propulsion that threatens to overthrow the laws of physics as we know them? That its inventor claims it could allow us to travel to the Moon in four hours without the use of fuel? What if I then told you we cannot explain exactly how it works and, in fact, there are some very good reasons why it shouldn’t work at all? By Steven Thomson.

Blue moon: how to see tonight’s 'rare' event

If it is clear tonight, step outside and marvel at the full moon. Its heavy, illuminated orb will trace a path right across the sky from horizon to horizon during the twilight and nighttime hours. It will be shining in the reflected light of the Sun, as normal, and will appear yellow/white, as normal, yet we call it a blue moon because, well … here’s where the story gets interesting.

The First Humans to Live to the Age of 150 Are Already Alive

Human lifespans are now longer than ever. Currently, the average 65-year-old can expect to live an additional 19.3 years compared to just 1950, when their same-age counterpart would only live approximately 13 more years, according to the National Institute on Aging. And the population of adults 85 and older is projected to increase 351 percent by 2050. Think that’s astonishing? The first humans expected to live to age 150 are already alive, according to experts on aging and longevity.

The sordid history of Australian heart transplants

The rigmarole of constant checks and consent forms in modern hospitals can be tiring, but as medical historian Dr John Carmody notes, it may be preferable to the alternative. He casts an eye back to the late ‘60s, where Australia's first heart transplants revealed the wild—and occasionally unethical—side of surgery.

Then those polymers developed a mechanism that allowed them to self-replicate and pass their structure on to future generations...

This Cold War Debate Shows the Role Scientists Should Play in Politics

On Feb. 20, 1958, in the midst of an escalating number of nuclear weapons tests worldwide—25 in 1955, 55 in 1957, nearly 120 in 1958—two scientists met in San Francisco for a live televised debate over nuclear weapons testing, fallout, and disarmament. In front of big block letters reading KQED, the call sign of the public television station, sat Linus Pauling, the 1954 Nobel laureate in chemistry and a compelling voice in the push for world peace through nuclear disarmament.
