Advanced light source sets microscopy record

Berkeley Lab researchers achieve highest resolution ever with X-ray microscopy

15-09-2014

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or "soft" X-rays to image structures only five ...

Faster, cheaper tests for sickle cell

Newly developed test can identify sickle cell disease in minutes and could be used in rural clinics around the globe

03-09-2014

Within minutes after birth, every child in the U.S. undergoes a battery of tests designed to diagnose a host of conditions, including sickle cell disease. Thousands of children born in the developing world, however, aren't so lucky, meaning many suffer and die from the disease each year. A.J. ...

Genomic sequencing reveals mutations, insights into 2014 Ebola outbreak

Broad researchers and colleagues find clues about origin, transmission of deadly virus

01-09-2014

In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health and Sanitation and researchers across institutions and continents, has ...

New analytical technology reveals 'nanomechanical' surface traits

01-09-2014

A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries. This new technique, called nanomechanical Raman spectroscopy, reveals ...

No excess baggage: Antarctic insect's genome, newly sequenced, is smallest to date

Researchers suggest bare-bones genome is adaptation to deep freeze

14-08-2014

Scientists who sequenced the genome of the Antarctic midge suspect the genome's small size – the smallest in insects described to date – can probably be explained by the midge's adaptation to its extreme living environment. The midge is a small, wingless fly that spends most of its two-year ...

Tiny laser sensor heightens bomb detection sensitivity

24-07-2014

New technology under development at the University of California, Berkeley, could soon give bomb-sniffing dogs some serious competition. A team of researchers led by Xiang Zhang, UC Berkeley professor of mechanical engineering, has found a way to dramatically increase the sensitivity of a ...

Rice nanophotonics experts create powerful molecular sensor

Sensor amplifies optical signature of single molecules about 100 billion times

23-07-2014

Nanophotonics experts at Rice University have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 ...

'Nanocamera' takes pictures at distances smaller than light's own wavelength

How is it possible to record optically encoded information for distances smaller than the wavelength of light?

22-07-2014

Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances ...

NMR under pressure: Reproducing deep-Earth chemistry

16-07-2014

A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth's crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid at pressures up to 20 kiloBar. "NMR is our ...

Sophisticated radiation detector designed for broad public use

14-07-2014

Nuclear engineers at Oregon State University have developed a small, portable and inexpensive radiation detection device that should help people all over the world better understand the radiation around them, its type and intensity, and whether or not it poses a health risk. The device was ...
