New model developed to study inflammatory bowel disease in human biopsy samples

04-Nov-2016

Inflammatory bowel disease (IBD) is a complex condition that requires a lifetime of care and increases a person's cancer risk. But its origins are still a mystery. Now, a team of researchers have created a new culture model of the human intestine where living tissue from a patient biopsy can be ...

Water and light 'flow' inspire ultrasensitive optical microfiber coupler sensor

07-Sep-2016

When a river narrows or two rivers run into each other and merge, the water flow's speed increases and it becomes much stronger. Water flow and light flow are similar in many ways, and this inspired a group of researchers from Nanyang Technological University in Singapore and the University of ...

Hexagonal boron nitride semiconductors enable cost-effective detection of neutron signals

18-Aug-2016

One of the most critical issues the United States faces today is preventing terrorists from smuggling nuclear weapons into its ports. To this end, the U.S. Security and Accountability for Every Port Act mandates that all overseas cargo containers be scanned for possible nuclear materials or ...

Laboratory breakthrough may lead to improved X-ray spectrometers

09-Jun-2016

Researchers at the Paul Scherrer Institute's Swiss Light Source in Villigen, Switzerland, have developed a new design for X-ray spectrometers that eschews a commonly utilized component to lowers overall production costs and increase the efficiency of x-ray flux, which may lead to faster ...

Tiny probe could produce big improvements in batteries and fuel cells

02-Jun-2016

A team of American and Chinese researchers has developed a new tool that could aid in the quest for better batteries and fuel cells. Although battery technology has come a long way since Alessandro Volta first stacked metal discs in a "voltaic pile" to generate electricity, major improvements are ...

Closing in on the elusive rotational-vibrational CH5+ spectra

25-May-2016

Protonated methane, a.k.a. CH5+, is a highly unusual molecule that scientists and astronomers suspect may be found within the interstellar medium where stars and planets are formed. To identify molecules on Earth or in outer space, scientists typically record the spectrum of light absorbed -- ...

Better biopsies through biofluidics

03-Mar-2016

Biopsies are a gold standard for definitively diagnosing diseases like cancer. Usually, doctors can only take two-dimensional snapshots of the tissue, and they're limited in their ability to measure the protein levels that might better explain a diagnosis. But now, researchers have developed a ...

Saliva test to detect GHB and alcohol poisonings

08-Jan-2016

Scientists working at Loughborough University, UK, and the University of Cordoba, Spain, have developed a new method for the rapid diagnosis of poisoning in apparently drunk patients. The saliva-based test offers the potential to screen for poisons commonly associated with the cheap or imitation ...

Thermal microscopy of single cells

05-Jan-2016

Thermal properties of cells regulate their ability to store, transport or exchange heat with their environment. So gaining control of these properties is of great interest for optimizing cryopreservation -- the process of freezing and storing blood or tissues, which is also used when transporting ...

Milestone single-biomolecule imaging technique may advance drug design

01-Oct-2015

Knowing the detailed shape of biomolecules such as proteins is essential for biological studies and drug discovery. Modern structural biology relies on techniques such as nuclear magnetic resonance (NMR), X-ray crystallography and cryo-electron microscopy to discover the tiny structural details ...
