Near ground-state cooling of 2-D trapped ion crystals

Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...

Sculpting stable structures in pure liquids

Oscillating flow and light pulses can be used to create reconfigurable architecture in liquid crystals. Materials scientists can carefully engineer concerted microfluidic flows and localized optothermal fields to achieve ...

How to freeze heat conduction

Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy.

Amazon's exit could scare off tech companies from New York

Amazon jilted New York City on Valentine's Day, scrapping plans to build a massive headquarters campus in Queens amid fierce opposition from politicians angry about nearly $3 billion in tax breaks and the company's anti-union ...

X-rays reveal layout of loaded drug transporter

Experiments at DESY's X-ray source PETRA III have revealed the first structure of a biological transporter protein loaded with a pro-drug. Prodrugs are inactive medications that are metabolized into an active, functional ...

Simulating meteorite impacts in the lab

A U.S.-German research team has simulated meteorite impacts in the lab and followed the resulting structural changes in two feldspar minerals with X-rays as they happened. The results of the experiments at DESY and at Argonne ...

Ceramic holds promise for greener optical devices

A lead-free ceramic that could be used in applications ranging from optical sensors and switches to creams for protecting against ultraviolet (UV) light has been developed by A*STAR researchers.
