Over the past year, there’s been a whole lot of excitement about the electromagnetic propulsion drive, or EM Drive – a scientifically impossible engine that’s defied pretty much everyone’s expectations by continuing to stand up to experimental scrutiny.

The Standard Model is the mainstream theory of all the fundamental particles that make up matter, and the forces that govern them. But the model has weaknesses: it doesn’t explain dark matter or dark energy, which jointly make up 95 percent of the universe. Nor is it compatible with Einstein’s theory of general relativity the force of gravity as we know it does not seem to work at the subatomic quantum scale.
Fifty years ago, Bob Dylan had only just gone electric, mankind had yet to take its great leap and many people thought the Big Bang was something that happened when you burst a Big Balloon.
But in July 1965, Arno Penzias and Robert Wilson made a discovery that would cement our understanding of how the universe came into being. Their detection of the Cosmic Microwave Background (CMB), the radiation left over from the birth of the universe, provided the strongest possible evidence that the universe expanded from an initial violent explosion, known as The Big Bang. Today, the CMB is still one of the most important signals that helps us understand the cosmos.
Using advanced computers and a computational technique to simulate physical processes at the atomic level, researchers at Brown University have predicted that a material made from hafnium, nitrogen, and carbon would have the highest known melting point, about two-thirds the temperature at the surface of the sun.
Traveling to other star systems is a big dream, but achieving it may require going ultrasmall.
Blasting tiny, waferlike sailing spacecraft with powerful lasers could slash interstellar flight times from thousands of years to mere decades, one researcher says.
Osaka University scientists said they fired the world’s most powerful laser beam.
It instantaneously concentrated energy equivalent to 1,000 times the world’s electricity consumption and entered the record books as the most powerful laser beam ever emitted.

When I arrived in San Jose last night, the newspaper on the front desk at the hotel had this headline splashed across the front page: “Drones Putting Lives at Risk.” At least five times this year, fire departments trying to battle wildfires in California were unable to fly their helicopters close enough to assist teams on the ground because small drones flown by ordinary citizens were in the airspace capturing footage of the blaze.
The test flight of two small electric aircrafts earlier this month across the English Channel has got us wondering about when we’ll get to ride in one of these clean, green planes.
While it may be a while before we board a cross-country electric flight, a short hop to the islands off Cape Cod may be more realistic.
In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in a wind tunnel. While the general approach to harvesting energy from these “aeroelastic” vibrations is to attach the beam to a secondary vibrating structure, such as a wing section, the new design eliminates the need for the secondary vibrating structure because the beam is designed so that it produces self-induced and self-sustaining vibrations.
The light-sensing molecules that tell plants whether to germinate, when to flower and which direction to grow were inherited millions of years ago from ancient algae, says a new study released in the journal Nature Communications.
Taste, the sense that allows us to appreciate the beauty of good food, is something scientists understand fairly well. The sensation we feel when eating a piece of cake, chewing on a hamburger or taking the first bite of a piping hot piece of pizza is triggered when chemicals in our food interact with receptors in our mouths.
Anxiety and depression could be linked to the presence of bacteria in the intestines, scientists have found.
A study on laboratory mice has shown that anxious and depressive behaviour brought on by exposure to stress in early life appears only to be triggered if microbes are present in the gut.
The pygmies of West Africa evolved their short stature independently, and very differently, from their cousins in East Africa, French researchers said Tuesday.
The finding is evidence for the theory that dwarfism is an adaptation to environmental conditions—in this case life in an equatorial rain forest, they wrote in the journal Nature Communications.
One man was thought to be the first Anglican minister in the Americas. Another, an early explorer of the Mid-Atlantic region, was a rival of Capt. John Smith’s. And two of them, kin of Sir Thomas West’s, the governor of Virginia, helped save a colony on the brink of collapse.
All four, some of European America’s earliest leaders, died in colonial Jamestown from 1608 to 1610 and were long thought lost to history.

Sibudu, a rock shelter above the uThongathi River in KwaZulu-Natal, is one of South Africa’s most important archaeological sites. Its recent nomination for World Heritage status demonstrates that it is of universal value, with heritage that belongs to all humanity.
Crouched in a shallow square grid dug into the red African earth, American graduate student Sarah Edlund uses a hand brush to scrape soil into a dustpan.
She is uncovering scraping tools of a different kind — implements fashioned from quartz that were used 100,000 years ago to prepare animal hides.
New research reveals that some of the earliest civilizations in the Middle East and the Fertile Crescent may have been affected by abrupt climate change. These findings show that while socio-economic factors were traditionally considered to shape ancient human societies in this region, the influence of abrupt climate change should not be underestimated.
