MIT team enlarges brain samples, making them easier to image

January 16, 2015 11:46 am | by EurekAlert! | Comments

Beginning with the invention of the first microscope in the late 1500s, scientists have been trying to peer into preserved cells and tissues with ever-greater magnification. The latest generation of so-called "super-resolution" microscopes can see inside cells with resolution ...

Planetary dashboard shows 'Great Acceleration' in human activity since 1950

January 16, 2015 11:44 am | by EurekAlert! | Comments

Human activity, predominantly the global economic system, is now the prime driver of change in the Earth System (the sum of our planet's interacting physical, chemical, biological and human processes), according to a set of 24 global indicators, or "planetary dashboard" ...

Rice-sized laser bodes well for quantum computing

January 16, 2015 11:38 am | by EurekAlert! | Comments

Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental interactions between ...

Training the next generation of power engineers

January 16, 2015 11:34 am | by EurekAlert! | Comments

Most people only think about the electricity that powers our homes and gadgets when it isn't there. When the power is humming, we tend to take it for granted. The trouble is, the network that delivers the electricity to keep our lights on, known as the grid ...

Planets outside our solar system more hospitable to life than thought

January 16, 2015 11:29 am | by EurekAlert! | Comments

A study by astrophysicists at the University of Toronto suggests that exoplanets - planets outside our solar system - are more likely to have liquid water and be more habitable than we thought. "Planets with potential oceans could have a climate that is much ...

Improved interface for a quantum Internet

January 16, 2015 9:25 am | by University of Innsbruck | Comments

Quantum computers are no longer just a theoretical concept. In recent years, researchers have assembled and successfully tested the building blocks for a future quantum computer in the laboratory. More than a dozen candidate technologies are currently ...

Shining a light on quantum dots measurement

January 16, 2015 9:01 am | by EurekAlert! | Comments

Due to their nanoscale dimensions and sensitivity to light, quantum dots are being used for a number of bioimaging applications including in vivo imaging of tumor cells, detection of biomolecules, and measurement of pH changes. When quantum dots ...

Perovskites provide big boost to silicon solar cells

January 16, 2015 8:57 am | by EurekAlert! | Comments

Stacking perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford University scientists. The researchers describe their novel perovskite-silicon solar cell in this week's ...

Humanity has exceeded 4 of 9 'planetary boundaries'

January 16, 2015 8:54 am | by EurekAlert! | Comments

An international team of researchers says climate change, the loss of biosphere integrity, land-system change, and altered biogeochemical cycles like phosphorus and nitrogen runoff have all passed beyond levels that put humanity in a "safe operating space." Civilization has crossed ...

January 16, 2015 8:35 am | by Texas A&M University | Comments

The children’s social networking website known as KidGab was created by Texas A&M University Computer Science and Engineering Ph.D. student, Stephanie Valentine, who works in the Sketch Recognition Lab led by CSE associate professor, Dr. Tracy Hammond....

A galactic 'hailstorm' in the early universe

January 16, 2015 8:22 am | by EurekAlert! | Comments

Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous objects powered by ...

How does a machine smell?

January 16, 2015 8:16 am | by EurekAlert! | Comments

Every odour has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are mirror images of each other, so called chiral molecules ...
