Game-winning 'momentum' illusion is but a delusion
(Phys.org) —A hot hand may be hokum: Cornell researchers have examined the concept of "winning momentum" with varsity college hockey teams, and they conclude that momentum advantages don't exist, says...
View ArticleCarbon dioxide from exhaust fumes used to make new chemicals
To stop global warming, most governments are advocating reducing the amount of carbon dioxide (CO₂), a greenhouse gas, put into the atmosphere. But some argue that such action won't be enough – we will...

Nearly everything we know about the radiation exposure on a trip to Mars we have learned in the past 200 days.
View ArticleMoon rocks reveal surprising meteorite history
A WA geologist analyzing lunar rock samples collected during the Apollo missions has uncovered evidence of a huge meteorite strike 4.2 billion years ago.
View ArticleClimate change restricts migrant species access to oceans
(Phys.org) —Climate change has led to more than a third of the world's oceans becoming inaccessible to species that migrate seeking favourable climates.
View ArticleDrastic chemical change occurring in birth of planetary system: Has the solar...
A new star is formed by gravitational contraction of an interstellar molecular cloud consisting of gas and dust. In the course of this process, a gas disk (protoplanetary disk), whose size is on the...
View ArticleA battery small enough to be injected, energetic enough to track salmon
(Phys.org) —Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and...
View ArticleImage: Where's Gaia?
(Phys.org) —Disguised in a crowded field of stars, the tiny white dot highlighted in these two images is none other than ESA's Gaia satellite as seen with the Very Large Telescope Survey Telescope at...

(Phys.org) —Squinting close to the beginning of time, Dominik Riechers, Cornell assistant professor of astronomy, has discovered an association of gas-rich galaxies near the infancy of cosmic time....
View ArticleSimulations re-create X-rays emerging from the neighborhood of black holes
Black holes may be dark, but the areas around them definitely are not. These dense, spinning behemoths twist up gas and matter just outside their event horizon, and generate heat and energy that gets...
View ArticleScientists pinpoint the exact source of many of the rocks used to build...
A new study, published in the Journal of Archaeological Science, suggests that the site researchers had previously thought was the starting place of many of Stonehenge's rocks may not have been the...
View ArticleSea star wasting devastates Pacific Coast species
(Phys.org) —Sea stars off the Pacific Coast are dying en masse at an "unprecedented" rate and geographic spread, and Cornell researchers are trying to find out why.
View ArticleEinstein's conversion from a static to an expanding universe
Albert Einstein accepted the modern cosmological view that the universe is expanding long after his contemporaries, new study shows.
View ArticleCaps not the culprit in nanotube chirality
(Phys.org) —A single-walled carbon nanotube grows from the round cap down, so it's logical to think the cap's formation determines what follows. But according to researchers at Rice University, that's...
View ArticleWorld-record micrometer-sized converter of electrical into optical signals
Thanks to optical signals, mails and data can be transmitted rapidly around the globe. But also exchange of digital information between electronic chips may be accelerated and energy efficiency might...
View ArticleUnobtrusive, wearable blood pressure sensor for long-term continuous monitoring
A team of researchers in Korea have developed a wearable blood pressure sensor that is sufficiently compact and unobtrusive which can be used to provide long-term continuous monitoring without...
View ArticleAfter 400 years, mathematicians find a new class of solid shapes
The work of the Greek polymath Plato has kept millions of people busy for millennia. A few among them have been mathematicians who have obsessed about Platonic solids, a class of geometric forms that...
View ArticleGraphene-coated heart valves could sidestep harmful drugs
Every year thousands of people are fitted with artificial heart valves to replace their own malfunctioning valve. Many of these patients, however, have to remain on drugs that stop blood clotting on...
View ArticleFractal wire patterns enhance stretchability of electronic devices
(Phys.org) —Fractals—patterns defined by their scale-invariance that makes them look the same on large scales as they do on small scales—are found in nature everywhere from snowflakes to broccoli to...
