Battery breakthrough: Doubling performance with lithium metal that doesn’t catch fire

A rechargeable battery technology developed at the University of Michigan could double the output of today’s lithium ion cells — drastically extending electric vehicle ranges and time between cell phone charges — without taking up any added space. By using a ceramic, solid-state electrolyte, engineers can harness the power of lithium metal batteries without the…

New water simulation captures small details even in large scenes

When designers select a method for simulating water and waves, they have to choose either fast computation or realistic effects; state-of-the-art methods are only able to optimize one or the other. Now, a method developed by researchers at the Institute of Science and Technology Austria (IST Austria) and NVIDIA bridges this gap. Their simulation method…

Balloon-borne telescope looks for cosmic gamma rays

Cosmic gamma rays can provide us with important insights into the high-energy phenomena in our universe. The GRAINE (Gamma-Ray Astro-Imager with Nuclear Emulsion) collaboration aims to high resolution record high-energy cosmic gamma rays using a balloon-borne nuclear emulsion telescope. Nuclear emulsion film can record tracks of high-energy charged particles at the highest accuracy level in…

Amazingly ‘green’ synthesis method for high-tech dyes

They not only impress due to their radiant and intense colour, they also have an important technological significance: organic dyes are a class of materials with extremely special properties. From flat screens to electronic paper through to chip cards: in future, many technologies are likely to be based on organic molecules like these. Previously, such…

Organic makeup of ancient meteorites sheds light on early Solar System

The origin of organic matter found in meteorites that formed during the birth of the Solar System 4.5 billion years ago may provide key clues to understanding the birth of life here on Earth. It could also help astronomers investigate the potential habitability of other solar systems. The new research, confirms that organic materials accreted…

Experts highlight ebola vaccine progress and suggest next steps

Despite promising advances, important scientific questions remain unanswered in the effort to develop a safe and effective Ebola vaccine,  the experts review the current field of Ebola vaccine candidates and clinical trials and highlight key gaps in knowledge that need to be addressed by future research. Researchers at the National Institute of Allergy and Infectious…

Marine mammals lack functional gene to defend against popular pesticide

As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular human-made pesticide. The implications of this discovery, announced today in Science, led researchers to call for monitoring our waterways to learn more about…

Novel approach to coherent control of a three-level quantum system

For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure, in which a quantum system is integrated into a nanoscale mechanical oscillator in form of a diamond cantilever. The electronic spin is…

Recording every cell’s history in real-time with evolving genetic barcodes

All humans begin life as a single cell that divides repeatedly to form two, then four, then eight cells, all the way up to the ~26 billion cells that make up a newborn. Tracing how and when those 26 billion cells arise from one zygote is the grand challenge of developmental biology, a field that…
