A team of brilliant researchers at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have demonstrated a working particle accelerator, used to accelerate particles like electrons or protons to extremely high energies and probe the Universe’s secrets, which is the size of a typical silicon chip. Typically, particle accelerators range from a […]
Hey molybdenum, is it me or are you looking chubbier these days? The International Union of Pure and Applied Chemistry (IUPAC) has conducted more precise measurements, changing the official atomic weight of 19 elements. The changes are very small, but they are proof of technological improvements and are part of a regular effort to update […]
The experiment: two identical glass beakers filed with deionized water are put into contact. A voltage is applied ( 10,000 to 15,000 volts DC ) to the water inside the beakers and these glasses are slowly moved apart. An amazing physical phenomenon is then observed – a water bridge between the two beakers is formed, as […]
Using low-frequency laser pulses, a team of researchers has carried out the first measurements on a mineral called herbertsmithite. This (pretty awesome looking) mineral features a unique kind of magnetism. Insite it, magnetic elements constantly fluctuate, leading to an exotic magnetic state, unlike conventional magnetism in which all magnetic forces allign in the same direction […]
The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for solar cell efficiency: 44.7% That means that 44.7% of all solar energy (from the Ultraviolet to the Infrared) is gathered and transformed into electricity. After going into research just three […]
Even in these modern times, steam condensation is one of the main drivers of electricity production and clean water: It is part of the power cycle that drives 85 percent of all electricity-generating plants and about half of all desalination plants globally, according to the United Nations and International Energy Agency. So improving the efficiency […]
What you’re seeing above is the Hofstadter’s butterfly – a mathematical object describing the theorised behaviour of electrons in a strong magnetic field. It took physicists 40 years, but they have finally found experimental evidence that the model, proposed in 1976 by Douglas Hofstadter is valid. Thing is, to catch this kind of fractal butterfly, […]
Geophysicists trying to understand hotspot volcanoes have used a process known as seismic tomography and detected previously unknown finger-like structures of heat, some thousands of km long. The vast majority of volcanoes arises at contact zones between tectonic plates. However, another, entirely different type of volcano exists: hotspots are volcanic regions which can appear even […]
Somebody in Tokyo is reading Game of Thrones: the Japanese government has announced plans to create a wall of ice underneath the contaminated area to contain the water leaks from the Fukushima nuclear plant. Prime Minister Shinzo Abe said his administration will provide the money for this. “The government needs to resolve the problem by […]
Honeybees are exquisite and majestic beings, which have always caught the imagination of people. Bees are typically associated with feminine energy, because they are ruled by queens, particularly with the roman goddess Venus. In some cultures, bees also represent wisdom. From a biological point of view however, bees could be definitely associated with motherhood. Without bees, […]
Geophysical data from Greenland have revealed the existence of a canyon comparable in size with the Grand Canyon beneath the ice sheet. The canyon has the characteristics of a winding river channel and is over 750 km long and it is often as deep as 800 m. This immense feature is thought to predate humanity […]
Theoretical Physicists John Preskill and Spiros Michalakis sat down for a short talk in which they describe how quantum computing differs from the classical view (i.e. digital computers). They first go on about the fundamental, key aspect of the quantum world: the laws that describe and govern things at the tiniest level differ from those […]
Time and time again we’ve hailed on ZME Science the cultural and scientific advances graphene is about to bring to humanity. It’s the strongest material known so far, while also being the lightest, it can be magnetic and – something of uttermost important to science – it’s the best electrical conductor that we know of. […]
I’ve written about our incredible biological ability to gather information about our environment by sensing electromagnetic radiation. As complex as our eyes are however, light holds far more information than what we are able to perceive with our eyes. Science has given us the means to determine far more than just that there is a […]
What do volcanic eruptions, oil spills, sewages and chimneys all have in common? Not much at a first glance – but if you ask Peter Baines, a scientist at the University of Melbourne in Australia, they are tightly connected; in all these events, a fluid rises into a environment stratified by density (like the atmosphere […]
For many quantum mechanics is very hard to comprehend because so many of its insights are extremely bizarre (see spooky action at a distance or quantum entanglement) and counter-intuitive (for instance wave-particle duality, which is the idea that all things have both a wave- and particle-like nature). For many years scientists vacuum was synonymous with […]
Using an innovative technique that mathematically infers what the environment outside the lens’ perspective might look like based on how light enters the camera, researchers at Harvard University have managed to create 3D images using only one lens and without moving the camera. The findings could prove to be applicable to amateur and professional photographers […]
Temperature is an important physical parameter which greatly influences a system. Monitoring and/or manipulating this state parameter with great accuracy is thus of great importance to scientists. Recently, researchers part of DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program proved a new technique that allowed them to measure and control temperatures at the nanometer scale inside living cells. Measuring […]
Scientists at the University of Darmstadt, Germany have set a new record after they devised an experimental set-up that allowed them to stop light in its tracks for a full minute. During this time, the light could have traveled 18 million kilometers or roughly the equivalent of 20 there and back trips to the moon. Beyond […]
We all appreciate and love the sun’s gaze in the morning, but truth be told were it not for our planet’s protective magnetic fields the sun’s warm embrace would have suddenly turn into a death ray. So instead of scorching Earth, solar wind bounces off the magnetic field, which leads radioactive particles to circulate the […]
Water droplets, coffee granules, fragments of polystyrene and even a toothpick – all of these, and more, have been levitating and moving around in a Swiss laboratory lately; all of them lifted by sound waves, that is. This is the first time a device is capable of handling several objects simultaneously. This achievement was detailed […]
Understanding how supercooled water acts can be very important for understanding basic processes during cryoprotection – the preservation of tissues and/or organs by liquid nitrogen, with the purpose of thawing without damaging them. A team from the University of Arkansas have found that surprisingly, when cooled at extremely low temperatures, water turns into an entirely […]
Lots of volcanoes erupted in 2009 – but one of them really screamed out. Its unique howls provide a glimpse into the very heart of the volcano, and also in some unexplained processes that accompany an eruption. It’s not unusual for swarms of small earthquakes to precede a volcanic eruption – it’s quite common. As […]
A trio of papers recently published in Science link hydraulic fracking and geothermal energy production to numerous earthquakes in the United States. Most of these events have been relatively small, with a magnitude of under 5.0, but a few were quite significant – including the 5.6 event that hit Oklahoma on 6 November 2011, damaging […]
In the world of microelectronics, packing the most computing power you can squeeze in the smallest surface is the topmost priority. As powerful devices in term of computing become ever miniaturized, however, efficiently disposing of heat or keeping devices cool under a working temperature is one of the biggest challenges the industry is facing right […]
Scientists at the Laboratoire Charles Fabry (LCF) in Palaiseau and the University of Lille have for the very first time performed a direct measurement of a Van der Waals force – the weak intermolecular force that causes, in some cases when there isn’t a strong force present, to attract and “stick” to one another. The Van […]
It’s the world of science fiction come alive – Swiss researchers have developed contact lenses which, when paired with special spectacles, bestow telescopic vision on their wearers. Cool, and very useful The contact-lens-and-spectacles have the ability of zooming in 2.8 times. The device was not created for Bond-like purposes, but rather to help people suffering […]

Scientists from Department of Earth Sciences at the University of Oxford have analyzed the compositions of Martian meteorites found on Earth and data from NASA’s rovers, and they reached the conclusion that the Red Planet had an atmosphere pretty rich in oxygen 4 billion years ago. They compared Martian rocks with meteorites, and the fact […]
Rock permeability in the geologic fault that unleashed China’s 2008 quake shows that fractures mend quicker than was thought. A devastating earthquake The 2008 Sichuan earthquake struck at 02:28:01 PM China Standard Time, with a magnitude of 8. It came as quite a surprise, as the area is not particularly active from a seismic point […]
Most certainly, one of the top goals in physics today is proving the existence of dark matter – the elusive form of matter that makes up 85% of all matter in the Universe. Many theories have been proposed and tested, however to this day we only have glimpses and possible hints of dark matter. A […]
It’s not a well known problem by most, but those who work in the field are very aware of it – medical isotopes are a very valuable commodity. But now, a Canadian team may have very well found a way to end the shortage, developing and upgrade that allows hospital cyclotrons to make a much-needed […]
Invisibility cloaks have become the object of study for many research institutes out of a number of considerations. There’s the simple scientific thrill of breaching the SciFi barrier, something every researcher dreams of. Then of course, there’s always the corporate and military tail that always likes to meddle with concepts that shine with the possibility […]
As bad as earthquakes can be, and we’ve recently had our fair share of earthquakes around the world, the tsunamis they generate can be even worse. When an earthquake has a significant effect in a body of water, it displaces large quantities of water – and it is that displacement which causes the huge waves […]
Hydrogen is the most common element in the Universe. It’s the first element in the periodic table, and it has but one proton and one electron. Understanding how it behaves at very large pressures is crucial to our understanding of matter and the nature of hydrogen-rich planets. Under typical conditions, Hydrogen is a diatomic molecule […]
A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles, similar in many ways to a fundamental particle postulated by Paul Dirac in 1931. Monopoles and Dipoles Until now, a magnetic monopole, the magnetic analogue to an electric charge has never been observed – all we had until now […]
It seems like every week there’s a new study that hails a new wonder property or fantastic application for graphene. Is it truly the material of the future that will catapult technology to the next level? Seems like it. For instance, scientists at Nanyang Technological University (NTU) in Singapore used graphene as the basis for a novel […]
In terms of materials, graphene is definitely the hot cherry at the moment; it is basically a one-atom thick layer of the mineral graphite (carbon), with more such layers stacked together forming crystalline graphene. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams, but also very durable and has a number of […]
This ancient Egyptian trinket may not look like much, but it hides a very interesting story. Researchers have found that the 5,000-year-old iron bead is actually made from a meteorite. Archaeologists have found iron objects in ancient Egypt, dating them to 2-3 millennia BC. But the earliest evidence of smelting only appeared much later […]
Black holes are the single most interesting and puzzling objects in our Universe – that we know of. But as if they weren’t mysterious enough, researchers have found that if you apply a quantum theory of gravity to these bizarre objects, the all-crushing singularity at their core disappears, opening a whole new Universe of possibilities […]
Over the past decades, what we mean by glue has changed significantly; techniques have emerged, materials have been developed, and one of the most viable candidates for a superglue is gold. Researchers have found numerous applications for attaching molecules to gold; the approach uses chemicals called thiols to bind the materials together. But while this […]
In a never-before seen feat, astronomers using NASA’s Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, something which can provide valuable clues to understanding these mysterious objects. Neutron stars Neutron stars are the cores of former high-mass stars, the remains of supernovae after the blow-up. As the core of the massive […]
While time can be viewed in very abstract terms, man has always been aware of it. Early man just needed to look towards the sky, at the sun and the moon, to instantly know that the Universe is moving forward and things are changing. Clocks, along with measures of time like the second, minute, years […]
While browsing reddit, I came across something well worth sharing: shrunken coins. Now, bear with me and you’ll soon learn why these are really interesting, if you the photos themselves haven’t caught your fancy. You see all these coins have been shrunk by powerful magnetic fields created by high power coils inside a machine appropriately […]
3D printing is the stuff of the future, today. Basically you can create absolutely anything, just by using a digital computer model of it.

[…]
Summer’s just around the corner, for those of us living in the northern hemisphere at least, and while we’ve been yearning for it all winter long, the scorching noon heat wave is here to remind us that summer’s not all fun and games. If you’re a commuter, then most likely summer’s your biggest worst enemy […]
Scientists closely working with the Large Hadron Collider, the largest and most powerful particle accelerator in the world, have identified evidence of the minuscule droplets produced in the aftermath of high energy proton and lead ions collisions. If their calculations are right, then these are the smallest droplets of liquid ever encountered thus far, just three to […]
Yesterday, residents in many parts of the US were treated to a wonderful sight as the sun became wrapped in a rainbow halo. Like a brilliant all seeing eye, the sun cast its rays from a most privileged position prompting some unsuspecting people to believe an alien invasion is nigh. ZME Science folks, however, know […]
The nucleus of an atom is closely shaped like a sphere or rugby ball, signifying that mass is evenly distributed inside it. What happens when you encounter an atom whose nucleus stays away from this conventional shape? Well, this would be a good hint to start finding alternative theories, and wouldn’t you know it scientists […]
How do you check a multi-billion dollar particle accelerator for defects or malfunctions? Sure, you could use various, equally expensive and sophisticated tools, but in some instances low tech comes in the aid of high tech, say a ping-pong ball. Wait, what ?! Yup, today researchers sent a carefully sterilized, slightly-smaller-than-regulation ping-pong ball through a 2-mile […]
