Sunswift, a team of engineering students from the University of New South Wales, designed and built a car that holds the Guinness World Record for the fastest solar-powered vehicle. In 2011, that car reached a top speed of 88 km/h (55 mph). The team hopes that its newest vehicle, eVe, will break a 20-year-old electric vehicle record for the highest average speed over a 500 km (310 mi) distance.
The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The researchers believe the answer may be hidden in some currently unknown physical process that governs how gas flows in the universe, although, as yet, there is no obvious mechanism that can guide dwarf galaxies into narrow planes.
Protons have a constant spin that is an intrinsic particle property like mass or charge. Yet where this spin comes from is such a mystery it’s dubbed the “proton spin crisis.” Initially physicists thought a proton’s spin was the sum of the spins of its three constituent quarks. But a 1987 experiment showed that quarks can account for only a small portion of a proton’s spin, raising the question of where the rest arises. The quarks inside a proton are held together by gluons, so scientists suggested perhaps they contribute spin.
STICK an electrode in the ground, pump electrons down it, and they will come: living cells that eat electricity. We have known bacteria to survive on a variety of energy sources, but none as weird as this. Think of Frankenstein's monster, brought to life by galvanic energy, except these "electric bacteria" are very real and are popping up all over the place.
There are a whole lot of unsavory lifestyles in the animal kingdom. The pearlfish has to swim up sea cucumber butts to escape predation. All manner of birds must fly thousands and thousands of miles each year with the change of the seasons. And hyenas have to deal with giving birth through their six-inch-long clitorises.
Over a 150 years since it was first described by Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue.
The fantastical arch shapes of sandstone formations have long been thought to be sculpted by wind and rain. But a team of researchers has now found that the shapes are inherent to the rock itself.
California businessman Russ George made headlines in 2012 when he, in cooperation with a group from a Native Canadian community, dumped more than 100 tons of iron sulfate into the Pacific, some 200 miles off shore. The iron then triggered a bloom of plankton. He apparently didn't ask anybody's permission, violated two United Nations conventions, and was widely condemned for taking on such a large project, a type of geoengineering, to alter the environment as he saw fit.
The Sea of Tranquility remains tranquil today, but it may not always be so. The site, where Neil Armstrong became the first person to walk on the moon 45 years ago this Sunday, has apparently been undisturbed since then. But a growing number of countries, including China and India, are planning moon missions, and new commercial space players may make lunar landings well. Some historians and archaeologists want the areas protected from visitors, both human and robotic, but there is no legal framework for safeguarding anything on the moon.
Black holes might end their lives by transforming into their exact opposite — 'white holes' that explosively pour all the material they ever swallowed into space, say two physicists. The suggestion, based on a speculative quantum theory of gravity, could solve a long-standing conundrum about whether black holes destroy information.
A small team of people gathered in the Nevada desert earlier this week to take another step toward answering one of mankind’s most pressing questions: What does beer taste like in space?
Researchers have made an important step in the race to discover whether other planets could develop and sustain life. New research shows the vital role of oceans in moderating climate on Earth-like planets Until now, computer simulations of habitable climates on Earth-like planets have focused on their atmospheres. But the presence of oceans is vital for optimal climate stability and habitability.
In about a billion years our aging sun will become hot enough to boil off Earth's oceans. But we needn't let our world bake to death. By devising a megastructure called a Shkadov Thruster, we could cruise our solar system—sun, planets, and all—close enough to a younger star for it to gravitationally capture Earth. By enabling us to swap our sun for another, the Shkadov Thruster could give the planet's biota a brand new lease on life.
A new material structure developed at MIT generates steam by soaking up the sun.
Sverker Johansson could be the most prolific author you've never heard of.
When faced with choosing the shortest queue at a supermarket, what do you do? Nobody starts counting – what our brain does is “number sensing”.
A Dutch cyclist, riding for the Terrengganu team in Malaysia, has escaped death twice after being scheduled to fly on both doomed Malaysian Airline flights but changing his plans at the last minute.
