Ultrathin protective layer brings quite a bit more stability to perovskite solar cell

(Eindhoven University of Technology) The addition of a few nanometers of a thin layer of aluminum oxide protects a perovskite solar cell against humidity -- still a major stumbling block to the commercial application of this new type of solar cell. Show More Summary

Rapid validation for genome assemblies? Introducing KAT: K-mer Analysis Toolkit

(Earlham Institute) A new bioinformatics tool has been released by the Earlham Institute that provides rapid validation for whole genome sequencing data as well as genome assemblies produced from Next Generation Sequencing (NGS) dat...

Tetrapod Triumph! Solving Mystery Of First Land Vertebrates

Let's talk about Romer's Gap, not to be confused with the Gap of Rohan (though I would love to talk about that, too, as I am always up for a bit of Tolkien). Romer's Gap is an intriguing question mark in the fossil record that todayShow More Summary

All Human-Made Objects on Earth Amount to 30 Trillion Tons

Pile up all of the human-made structures on the planet — from skyscrapers to cell phones — and it’d weigh in at approximately 30 million metric tons, according to a new study.

Why Do Our Feet Smell Worse in the Winter?

Do you think foot odor is a worse problem in the summer or the winter? Summer seems like the common sense answer, but the opposite is true.

New neuron dynamics model better fitted to the biological reality

(Springer) Neuroscientists are currently working diligently to understand the dynamics of thousands of coupled neurons. Understanding how they operate requires accurate models. The trouble is that each of the existing neuroscience models has its own shortcomings. Show More Summary

A handful of photos yields a mouthful of (digital) teeth

(Disney Research) A Disney Research team has developed a model-based method of realistically reconstructing teeth for digital actors and for medical applications using just a few, non-invasive photos or a short smartphone video of the mouth.

Confirmation of Wendelstein 7-X magnetic field

(DOE/Princeton Plasma Physics Laboratory) Physicist Sam Lazerson of the US Department of Energy's Princeton Plasma Physics Laboratory has teamed with German scientists to confirm that the Wendelstein 7-X fusion energy device called a stellarator in Greifswald, Germany, produces high-quality magnetic fields that are consistent with their complex design.

Time constraints and the competition determine a hunter's decision to shoot

What prompts a hunter to shoot an animal after it is spotted? Researchers studied more than 180,000 choice situations where hunters had spotted an animal and had to decide whether or not to shoot. They found that competition among hunters and the season coming to an end led to an increased likelihood of pulling the trigger. Show More Summary

Tunneling holds key to high-speed modulation of transistor and laser development

(University of Illinois College of Engineering) In 2004, electrical engineering pioneers Nick Holonyak Jr. and Milton Feng at the University of Illinois invented the transistor laser -- a three-port device that incorporated quantum-wells in the base and an optical cavity -- increasing its capacity to transmit data one hundred-fold.

What Tangled Web: Galaxy's Messy 'Threads' Star in New Pic

A striking new image from the Hubble Space Telescope captures an extremely detailed view of the galaxy NGC 4696 and the tangled, thread-like filaments stretching from its bright galactic core.

3D-Print Your Laugh and Launch It Into Space

Are you a chortler? What about guffaws, giggles or hyena laughs? If you have the best laugh, whatever the joyful sound, it could end up getting turned into a 3D-printed sculpture sent into space.

'Mythical' Sea Blob Finally Spotted a Century After Its Discovery

A mysterious giant sea blob whose very existence was questioned has been rediscovered a century after its first sighting.

In Photos: Gorgeous Sea Blob in Monterey Bay

A larvacean with a giant mucus house glides through the water, filtering out goodies to snack on.

SpaceShipTwo 'Unity' Flies Solo For First Time | Video

The Virgin Galactic suborbital vehicle entered its second phase of testing on Dec. 3, 2016. It was released from its WhiteKnightTwo mothership and glided back down to the Mojave Air and Space Port in California after 10 minutes of flight.

World's first gas sensor to apply a new principle for graphene use

Fujitsu Laboratories today announced the world's first successful development of an exquisitely sensitive gas sensor based on a new principle that takes advantage of graphene, a material in which carbon atoms are arranged in a sheet one atom thick. Show More Summary

Coaxial nanotubes used to improve performance of lithium-sulfur batteries

(Phys.org)—A team of researchers at the University of Texas has found that using coaxial nanotubes can improve the performance of lithium-sulfur batteries (Li-S). In their paper published in the journal Nano Letters, the team describes how they used Polypyrrole-MnO2 coaxial nanotubes to overcome obstacles to using Li-S batteries in commercial products.

How can we measure the 'interdisciplinarity' of research?

A report by Digital Science published today, raises questions important to the production of better indicators of research activity.

Manchester researchers map out the city's diverse language landscape

A team of researchers from The University of Manchester has embarked on a project to map multilingual signs around the city, in an effort to raise awareness of its language diversity.
