What a Newfound Kingdom Means for the Tree of Life
Posted on Tuesday December 11, 2018

Neither animal, plant, fungus nor familiar protozoan, a strange microbe that sits in its own “supra-kingdom” of life foretells incredible biodiversity yet to be discovered by new sequencing technologies.

In the Universe of Equations, Virtually All Are Prime
Posted on Monday December 10, 2018

Equations, like numbers, cannot always be split into simpler elements.

Why Black Hole Interiors Grow (Almost) Forever
Posted on Thursday December 06, 2018

The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.

On the Best Use of Science to Safeguard Humanity
Posted on Wednesday December 05, 2018

For 50 years, the astrophysicist Martin Rees has contributed to our understanding of cosmology. Now he is speaking up about the promise and potential dangers of the science and technology that will arrive over the next 50 years and beyond.

What Defines a Stem Cell? Scientists Rethink the Answer
Posted on Tuesday December 04, 2018

As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.

Terahertz laser for sensing and imaging outperforms its predecessors
Posted on Tuesday December 11, 2018

A new terahertz laser is the first to reach three key performance goals at once -- high constant power, tight beam pattern, and broad electric frequency tuning -- and could thus be valuable for a wide range of applications in chemical sensing and imaging.

New method gives microscope a boost in resolution
Posted on Tuesday December 11, 2018

Scientists have been able to boost current super-resolution microscopy by a novel tweak. They coated the glass cover slip as part of the sample carrier with tailor-made biocompatible nanosheets that create a 'mirror effect'. This method shows that localizing single emitters in front of a metal-dielectric coating leads to higher precision, brightness and contrast in Single Molecule Localization Microscopy (SMLM).

Topological material switched off and on for the first time
Posted on Monday December 10, 2018

A new study represents a significant advance in topological transistors and beyond-CMOS electronics. First time that the topological state in a topological insulator has been switched on and off using an electric field. Researchers proved this is possible at room temperature, which is necessary for any viable replacement to CMOS technology in everyday applications.

Novel laser technology for microchip-size chemical sensors
Posted on Monday December 10, 2018

A special laser system has been developed, using two slightly different frequency combs. This allows for chemical analysis on tiny spaces -- it is a millimeter-format chemistry lab. With this new patent-pending technology, frequency combs can be created on a single chip in a very simple and robust manner.

Nanoglue can make composites several times tougher during dynamic loading
Posted on Monday December 10, 2018

Materials scientists have found that oscillating loads at certain frequencies can lead to several-fold increases in the strength of composites with an interface that is modified by a molecular layer of 'nanoglue.'
