James Cook University, University of Sydney and Queensland University of Technology scientists working with laser data from the Royal Australian Navy have discovered a vast reef behind the familiar Great Barrier Reef. JCU’s Dr Robin Beaman says the high-resolution seafloor data provided by LiDAR-equipped aircraft have revealed great fields of unusual donut-shaped circular mounds, each 200-300 metres across and up to 10 metres deep at the centre. […]

Using the world’s most powerful telescopes, an international team of astronomers has found a massive galaxy that consists almost entirely of dark matter. The galaxy, Dragonfly 44, is located in the nearby Coma constellation and had been overlooked until last year because of its unusual composition: It is a diffuse “blob” about the size of the Milky Way, but with far fewer stars. “Very soon after its […]

By Heather Somerville | SAN FRANCISCO SAN FRANCISCO Chinese powerhouse Didi Chuxing’s acquisition of Uber Technologies Inc’s China operations marked the biggest move yet toward consolidation in an industry that many investors and Silicon Valley pundits view as a winner-take-all game. On the day the Didi deal was announced earlier this month, Uber board member Bill Gurley said Uber’s rivals in other markets had a slim chance […]

In-depth review charts the scientific understanding of rainbows and highlights the many practical applications of this fascinating interaction between light, liquid and gas. There’s more to rainbows than meets the eye. Knowledge gained from studying these multicoloured arcs of scattered light can be incredibly useful in ways that may not immediately spring to mind. Rainbow effects can warn of chemical contamination in the atmosphere, help to develop […]

By Joseph Menn | SAN FRANCISCO SAN FRANCISCO Apple Inc issued a patch on Thursday to fix a dangerous security flaw in iPhones and iPads after researchers discovered that a prominent United Arab Emirates dissident’s phone had been targeted with a previously unknown method of hacking.   The thwarted attack on the human rights activist, Ahmed Mansoor, used a text message that invited him to click on […]

Can the woolly mammoth be brought back from the dead? Scientists say it’s only a matter of time. In fact this year, the International Union for Conservation of Nature issued its first official set of guidelines on resurrecting extinct species. What’s more, university research labs and non-governmental agencies have projects in motion to bring back extinct species. But is all of this a good idea? A new […]

Imagine how much dental care you’d need if you had 300 or more teeth packed together on each side of your mouth. Duck-billed dinosaurs (hadrosaurs), who lived in the Cretaceous period between 90 million and 65 million years ago, sported this unique dental system, which had never been fully understood until it was examined at the microscopic level through recent research conducted by Aaron LeBlanc, a University […]

Beginning “as early as next year,” Samsung may start selling refurbished smartphones directly to consumers. The new resale program is aimed at strengthening Samsung’s earnings as global phone sales slow down, according to report today citing “a person with direct knowledge of the matter.” Offering lower-cost refurbished phones could also help Samsung better compete against Chinese manufacturers whose cheap devices have cut into its sales, especially in […]

Are you ready for a smartphone battery that lasts twice as long as your current one? According to researchers, that battery is coming. MIT News reported this week that a new kind of lithium battery is on the way to being commercialized. Called lithium metal batteries, they can reportedly pack the same energy as standard lithium-ion cells in half the size — or put twice as much […]

By calling to their eggs, zebra finch parents may be helping their young prepare for a hotter world brought on by climate change. Uncovering such a mechanism represents a significant advance in the effort to understand how species are adapting to a warming climate. “Incubation calling,” paired with the ability of embryos to hear external sounds, is just one of an array of prenatal guidance tools shared […]

Researchers at the Faculty of Physics at the University of Warsaw, using the liquid crystal elastomer technology, originally developed in the LENS Institute in Florence, demonstrated a bioinspired micro-robot capable of mimicking caterpillar gaits in natural scale. The 15-millimeter long soft robot harvests energy from green light and is controlled by spatially modulated laser beam. Apart from travelling on flat surfaces, it can also climb slopes, squeeze […]

INTERNATIONAL.  Nearly all of the Chief Strategy Officers (CSOs) surveyed by Accenture (NYSE: ACN) around the world acknowledge that digital disruption will reshape their industries, but very few are equipped to navigate the change. Those who feel most prepared are embracing new strategic alliances, devising more collaborative ways of operating with partners, and making themselves indispensable within a broader ecosystem.  For the report ‘Thriving on Disruption’, the Accenture […]

As anyone who has driven a car or crossed a busy street knows, colors play a significant role in influencing people’s interactions with the world around them. And the color red, in particular, elicits the highest level of compliance for conformity with social norms. But according to new research co-written by a University of Illinois expert in product development and marketing, under certain conditions, the color red […]

At some point in their lives, 15 percent of people with diabetes will develop a painful and hard-to-treat foot ulcer. Twenty-four percent of those affected will require a lower-leg amputation because of it. And, in some instances, what seems like a harmless sore might even lead to death. A Northwestern University team has developed a new treatment for this severe and potentially deadly complication of diabetes. Called […]

Associate Professor Dr Joan Vaccaro, of Griffith’s Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called ‘T violation’ could be the origin of time evolution and conservation laws. “I begin by breaking the rules of physics, which is rather bold I have to admit, but I wanted to understand time better and conventional physics can’t do that,” Dr […]

Scientists sponsored by the Office of Naval Research (ONR) have genetically modified a common soil bacteria to create electrical wires that not only conduct electricity, but are thousands of times thinner than a human hair. As electronic devices increasingly touch all facets of people’s lives, there is growing appetite for technology that is smaller, faster and more mobile and powerful than ever before. Thanks to advances in […]

Engineers at the A. James Clark School of Engineering at the University of Maryland (UMD) demonstrate in a new study that windows made of transparent wood could provide more even and consistent natural lighting and better energy efficiency than glass. In a paper just published in the peer-reviewed journal Advanced Energy Materials, the team, headed by Liangbing Hu of UMD’s Department of Materials Science and Engineering and […]

Biologists studying a small, colorful fish in the Mediterranean Sea have discovered a new way in which a female can choose the best father for her offspring. The animal kingdom is full of elaborate traits and behaviors by which females choose mates. Even in species in which the female mates with multiple males, biologists have found evidence of “cryptic female choice” involving mechanisms in the reproductive tract […]

Has Samsung finally come up with a giant killer of a mobile device that can give it genuine leverage against Apple in that market? If the early reviews of the Galaxy Note 7 are any indication, that just might be the case. The Samsung Galaxy Note 7, set for release this week, has drawn almost unanimously positive reviews from technology media outlets. The Galaxy Note 7 is […]

While it already offers several ways for users to make video calls over various platforms, Google today launched a new phone-based app called Duo that’s designed for simplicity. Available for both Android and iOS smartphones, Google Duo doesn’t require anything more than a phone number to launch once the app is downloaded. Unlike Google’s Hangouts messaging, voice and video calling tool, people don’t even need Google accounts […]

The long hindwing tails sported by many moths have long been suspected as a strategy to confound predators. The moths are active mainly at night, so they don’t need a visual disguise — they need to avoid nocturnal hunters that navigate by sound. Researchers at the University of Washington and Johns Hopkins University took a detailed look at the acoustics of the common luna moth, to see […]

Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature, according to a paper published in the journal Physical Review Letters by theoretical physicists at the University of California, Irvine. “If true, it’s revolutionary,” said Jonathan Feng, professor of physics & astronomy. “For decades, we’ve known of four fundamental forces: gravitation, electromagnetism, and the strong […]

Researchers from Polytechnique Montréal, Université de Montréal and McGill University have just achieved a spectacular breakthrough in cancer research.
