Novel method improves the resolution of hard X-ray nanotomography

It's been a truth for a long time: if you want to study the movement and behavior of single atoms, electron microscopy can give you what X-rays can't. X-rays are good at penetrating into samples -; they allow you to see what happens inside batteries as they charge and discharge, for example -; but historically they have not been able to spatially image with the same precision electrons can.

New technology offers an alternative way to produce highly detailed images of the brain

The gold standard in functional brain imaging for over two decades, functional magnetic resonance imaging (fMRI) has transformed the landscape of research and clinical care. Yet, because of its cost and functional limitations, scientists have continued to look for new ways to see into the human brain.

Study: Individuals who recovered from depression had increased level of serotonin transporter

Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells.

Unknown root trait allows some cereal plants to grow deeper roots

A previously unknown root trait allows some cereal plants to grow deeper roots capable of punching through dry, hard, compacted soils, according to Penn State researchers, who suggest that harnessing the inherited characteristic could lead to crops better able to deal with a changing climate.

Two cryo-EM studies identify different types of ATP synthase organization

The mitochondrial ATP synthase is energy-converting macromolecular machine that uses the electrochemical potential across the bioenergetic membrane called cristae. This potential is maintained via a membrane curvature that is induced by ATP synthase assembled in dimers.

Researchers reconstruct the chewing motion of an early mammal

Paleontologists at the University of Bonn (Germany) have succeeded in reconstructing the chewing motion of an early mammal that lived almost 150 million years ago.

Advanced methodology reveals structures of Arp2/3 complex within cells

The cells in our body are in motion. Some migrate from A to B to heal wounds or fight pathogens. They do so with the help of small "feet" at the leading edge of migrating cells, so-called lamellipodia.

New technology predicts efficacy of transplanted hEPCs in early stages of ischemic disease

In recent years, the number of high-risk groups for ischemic diseases such as critical limb ischemia where tissues of toe may decay is increasing due to increase in the number of people with obesity, diabetes, and hypertension which are triggered by changes in dietary habits, and consumption of smoking and alcohol.

New study shows patients' own stem cells can be used to grow new bone

A new, groundbreaking study from the University of Bergen (UiB) shows that a patients' own stem cells can be used to grow new bone. This can potentially help millions of people who are partially edentulous and have insufficient bone for the placement of dental implants.
