This bacterium gets paid in gold

Harvesting solar fuels through a bacterium's unusual appetite for gold

11-Oct-2018

A bacterium named Moorella thermoacetica won't work for free. But UC Berkeley researchers have figured out it has an appetite for gold. And in exchange for this special treat, the bacterium has revealed a more efficient path to producing solar fuels through artificial photosynthesis. M. ...

Seeing how cells work as never before

17-Jul-2018

Yale is adding microscopy that provides an unprecedented view of specimens whose thickness had thwarted close inspection Biological structures exist and function in three dimensions, but the limitations of imaging technology have long meant that scientists could examine only two dimensions in ...

Novel PET tracer detects small blood clots

10-Jul-2017

Blood clots in veins and arteries can lead to heart attack, stroke, and pulmonary embolism, which are major causes of mortality. Researchers show that targeting GPIIb/IIIa receptors, the key receptor involved in platelet clumping, with a fluorine-18 (18F) labeled ligand is a promising approach ...

PET detects neuroinflammation in multiple sclerosis

16-Jun-2016

The triggers of autoimmune inflammation in multiple sclerosis (MS) have eluded scientists for many years, but molecular imaging is bringing researchers closer to identifying them, while providing a means of evaluating next-generation therapies for MS. More than 2.3 million people are affected by ...

PET points to tau protein as leading culprit in Alzheimer's

14-Jun-2016

Alzheimer's is a devastating and incurable disease marked by beta-amyloid and tau protein aggregations in the brain, yet the direct relationship between these proteins and neurodegeneration has remained a mystery. New molecular imaging research is revealing how tau, rather than ...

X-ray laser turns crystal imperfections into better images of important biomolecules

New method could remove major obstacles to studying structures of complex biological machines

12-Feb-2016

Often the most difficult step in taking atomic-resolution images of biological molecules is getting them to form high-quality crystals needed for X-ray studies of their structure. Now researchers have shown they can get sharp images even with imperfect crystals using the world's brightest X-ray ...

The transformation of cancer imaging: From shades of gray to living color

22-Dec-2015

Taken by Wilhelm Roentgen in 1895, the first X-ray produced was of his wife's hand. Roentgen received the first Nobel Prize in physics for his work, but his discovery of X-ray beams also changed the medical profession far more than that simple black-and-white image might have suggested. The beams ...

PET imaging detects fast-growing prostate cancer

24-Aug-2015

A molecular imaging biomarker is able to detect fast-growing primary prostate cancer and distinguish it from benign prostate lesions, addressing an unmet clinical need. The new research, published in The Journal of Nuclear Medicine, is significant for patients with suspected prostate cancer that ...

Nanotube coating helps shrink mass spectrometers

27-Mar-2014

Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. Researchers found that when paper used to collect a sample was coated with carbon nanotubes, ...

Let there be tissue-penetrating light

Scientists develop new nanoscale method to fight cancer

04-Mar-2014

Researchers from UCLA's Jonsson Comprehensive Cancer Center have developed an innovative cancer-fighting technique in which custom-designed nanoparticles carry chemotherapy drugs directly to tumor cells and release their cargo when triggered by a two-photon laser in the infrared red ...
