Synopsis: Cell Sensing Improves in a Loose Crowd

Cells that communicate with each other can measure chemical concentrations with higher precision if they spread out into a sparse configuration.   [Physics] Published Tue Feb 14, 2017

Physics love poems

Advance your romance with science. This Valentine’s Day, we challenged our readers to send us physics-inspired love poems. You answered the call: We received dozens of submissions—in four different languages! You can find some of our...Show More Summary

Optical fibre with Einstein effect

Researchers at the Max Planck Institute for the Science of Light in Erlangen have discovered a new mechanism for guiding light in photonic crystal fibre (PCF). PCF is a hair-thin glass fibre with a regular array of hollow channels running along its length. Show More Summary

Frequency combs—on-chip integration on track

EPFL scientists have found a way to miniaturize frequency combs, realizing a new step toward miniaturization of such tools. Their device can measure light oscillations with a precision of 12 digits.

NIST to launch a dramatically improved system for measuring the intensity and spectrum of light

We see the world in reflection: Nearly all the light that enters our eyes has bounced off something first, bringing with it information about the nature of the objects it encountered on the way. But that information is strongly affected by the angle at which the light strikes the object, and also the angle at which the reflected light reaches the eye of the beholder.

Searching for axion dark matter with a new detection device

A detection device designed and built at Yale is narrowing the search for dark matter in the form of axions, a theorized subatomic particle that may make up as much as 80% of the matter in the universe.

Green light for next-generation dark matter detector

Construction will begin on a next-generation dark matter detector with the UK taking a leading role and providing vital hardware for the project.

Squeezing of vesicles through narrow constrictions shows promise for targeted drug delivery

Vesicles, like living cells, are membrane-enclosed "sacs" of fluid that can cushion molecular cargo such as pharmaceutical drugs. If a drug is successfully encapsulated into a vesicle carrier and the carrier remains intact, it can be delivered directly for therapeutic treatment. Show More Summary

Researchers looking at how brittle materials fail

If you want to see what happens if your phone falls onto concrete, you can actually drop it or let an engineer work out the consequences in advance.

Researchers identify key components of blood that directly affect flow behavior

Cardiovascular diseases are the leading cause of deaths worldwide—yet researchers still don't fully understand how blood flows or even which components within blood can lead to cardiac issues.

Researchers explain the unique properties of hagfish slime

Hagfish are marine fish shaped like eels, famous for releasing large quantities of "slime" that unfolds, assembles and expands into the surrounding water in response to a threat or a predator's attack. This defense mechanism even works against sharks by effectively clogging their gills or choking them.

The mechanics of cavitation-induced injury lend a better understanding of blast traumatic brain injuries

Traumatic brain injury (TBI) is a largely silent epidemic that affects roughly two million people each year, according to the U.S. Centers for Disease Control and Prevention. But the scale at which blast TBI (bTBI) injuries—in the spotlight as the signature wound of the wars in Iraq and Afghanistan—occur and manifest is unknown.

Superconductivity with two-fold symmetry—new evidence for topological superconductor SrxBi2Se3

The study of topological superconductors (TSCs) is a hotspot in the field of condensed matter physics, and has drawn great attention in recent years. Now, Prof. Hai-Hu Wen's group from Nanjing University has succeeded in detecting the two-fold symmetry of superconductivity in SrxBi2Se3, which provides new evidence for the argument that SrxBi2Se3 is a TSC.

Researchers apply machine learning to condensed matter physics

A machine learning algorithm designed to teach computers how to recognize photos, speech patterns, and hand-written digits has now been applied to a vastly different set of data: identifying phase transitions between states of matte...

The return of supersolids

Stephen Ornes reports on how two groups may have finally observed supersolids

X-ray pulses reveal structure of viral cocoon: Scientists analyze smallest ever protein crystals

An international team of scientists has used high-intensity X-ray pulses to determine the structure of the crystalline protein envelope of an insect virus. Their analysis reveals the fine details of the building blocks that make up the viral cocoon down to a scale of 0.2 nanometres (millionths of a millimetre) - approaching atom-scale resolution.

LZ dark matter detector on fast track

Construction has officially launched for the LZ next-generation dark matter experiment. The race is on to build the most sensitive US-based experiment designed to directly detect dark matter particles. Department of Energy officialsShow More Summary

Viewpoint: Transportable Clocks Move with the Times
