It's Saturday, so time for some fun physics. This non-trivial question is often asked in international physics contests and requires a bit of out of the box thinking.
This is the first map in a series of maps that will be stitched together to form a grand picture of how dark matter is distributed across the Universe. Dark matter is basically invisible, which is why it's called dark in the first place, so scientists rely on indirect observations like the gravitational effects it poses to locate and map it. What we're seeing now is only 3% of the area of sky that the Dark Energy Survey (DES) will document over its slated five-year-long mission.
There's so much you can do with a smartphone today - much more than just browsing the web or social media. When you can combine them in a network, however, the possibilities might be endless. For instance, researchers at Caltech and the United States Geological Survey (USGS) are working on an earthquake early warning system based on the collective data fed in by thousands of smartphones. Only a couple of countries in the world give vulnerable cities an early warning - often just enough time to hit cover and save your life - but smartphones are virtually ubiquitous all over the world, even in poor countries which lack basic infrastructure like roads or flushing toilets.
Researchers from the University of Cambridge in England claim to have unraveled one of the great mysteries of electromagnetism, and believe their work in ultra-small antennas could not only revolutionize global communications, but also explain some of the tricky areas where electromagnetism and quantum physics overlap.
By the time you've finished reading this sentence, thousands of lightning bolts had already discharged enormous amounts of energy onto Earth's surface. Now, a map compiled by NASA using two decades worth of measurements shows which places are hit most often. For instance, land is hit more frequently than the ocean, as is the equatorial region compared to other regions of the globe.
Settling a long debate, Princeton University researchers found that a class of materials called frustrated magnets - called so because they're not magnetic, though they should be - can exhibit the Hall effect. This happens only at very, very low temperatures close to absolute zero, when physics transcends familiar, classical behavior into the quantum domain. First observed in 1879 by E.H. Hall, the effect describes how current deflects to one side of the ribbon when an electrically charged conductor is subjected to a magnetic field. It has since been exploited for use in in sensors for devices such as computer printers and automobile anti-lock braking systems. The current study is particularly important since it may reveal more about how transmission of frictionless electricity works (superconductivity), while also offering hints and clues that may help researchers devise the oh-so heralded quantum computers of the future.
It may be the dawn of a new age for particle physics - scientists and engineers are working together to restart the Large Hadron Collider. Upon reactivation, the LHC will be capable of energies never before achieved, potentially unveiling novel particles, confirming the Standard Model and revealing some of the Universe's biggest mysteries.
Extraordinaire experimental physicist Galileo Galilei allegedly climbed hundreds of step to reach the top of the Leaning Tower of Pisa’s – which wasn’t so leaned as it is today – and dropped pairs of balls of different weights and materials onto the ground. The experiment was meant to prove in front of the crowd of scholars […]
Scientists at the University of California, Santa Barbara, and at Google reported on Wednesday in the journal Nature that they are one step closer to developing a true quantum computer - they have developed a quantum device the art of checking and correcting its own errors.
We see light every day, and yet, we don't truly understand it; it's either a particle or a wave, or both at the same time... and we don't really know why. Now, for the first time, researchers have captured an image of light behaving as a particle and a wave at the same time.
If you've ever walked with beverages in your hand, you probably know that coffee tens to spill easily, while beer doesn't.

It’s hard to think that the crust’s thickness (which varies between several and several tens of km) can be affected by what happens on the surface – but that’s exactly the conclusion of a recent study conducted by British researchers. They found that during an ice age, when sea levels are low, the magma that spreads […]
A suborbital rocket carrying six research payloads was successfully launched into the Aurora Borealis. The probe will allow scientists to better understand the energy of the aurora and how this affects the Earth.
Nothing can travel faster than light in vacuum, per Einstein, but in the real world light travels at variable speed as it passes through a medium, be it air, water or glass. Physicists at University of Glasgow now demonstrate that its not only the medium that can slow down light, but also shape after they performed an experiment where light traveled through a ''mask".
Recently, a video published on Vine by Logan Gendizzle went viral. The video claims to show what the guitar strings look like up close while the author is playing Weezer’s “Say it Ain’t So”. The result is pretty spectacular, it got tons of shares and likes... and it's fake. The good news is that reality is even cooler.
Using a new X-Ray technique, archaeologists may be able to read the words from the charred, rolled up scrolls that survived the Vesuvius eruption that wiped out the Roman cities of Pompeii and Herculaneum nearly 2000 years ago. This could open up a new window to the past, revealing much information about the way the Romans lived and is a spectacular technological achievement in itself.
Princeton researchers demonstrated a novel type of microwave laser - called a maser - so small that's the size of a grain of rice. The laser is powered by individual electrons that tunnel through artificial atoms known as quantum dots.
Since the mid-XIXth century average global temperatures have risen by ~0.8 degrees Centigrade, yet this figure would have been much higher were it not for the world’s oceans ability to soak up most of the heat trapped by greenhouse gases. The IPCC estimates that some 90% of the heat trapped by CO2 and methane since […]
Security experts have devised a novel authentication system that exploits quantum effects to make fraud-proof credit cards or IDs.

Quantum physics keys “We experimentally demonstrate quantum-secure authentication (QSA) of […]
Superconductivity or zero electrical resistance at room temperature is any physicist’s dream, but so far the challenges have proven too great. Typically, metals like mercury become superconductive at temperatures close to absolute zero or -273 degrees Celsius. This means that we need to add a lot of energy to refrigerate the material so we might […]
All our modern electronics are based on a class of wonder materials called semiconductors. What makes these so valuable is their ability to free electrons when subjected to an electrical current or when hit by light, becoming mobile and eventually routed and switch through a transistor. It’s the very basis of our digital age, be […]

The accelerator ring at the Large […]
The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can’t see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye. Apparently, this isn’t entirely true. In some special conditions, the […]
A team of researchers from University of Wisconsin-Milwaukee (UWM) has revealed how the atomic structure of proteins changes during photosynthesis using an X-Ray laser which captures snapshops with unprecedented temporal resolution.

An innovative research posits that cancer may actually be a sort of 'safe mode' mechanism, akin to how a computer's operating system reverts back to safe settings to preserve itself, which evolved shortly following the first single celled organisms. The research was made by an unlikely team of scientists: an oncologist, an astrobiologist and a cosmologist. If the findings are right, then cancer may be fought off more effectively using oxygen treatments and infection with viral or bacterial agents.
