The atomic structure of nanocrystals

A new imaging technique overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom.

5 million atoms in viral coat

An image indicates that a viral capsid contains some 5 million atoms and it could help scientists find better ways to both fight viral infections and design new gene therapies.

Connection between brain and loneliness

Social isolation affects how people behave as well as how their brains operate, a study at the University of Chicago shows.

Synchrotron X-rays reveals hidden secrets

By looking for traces of specific elements left in the slab of limestone as the bird decomposed, the researchers hope to uncover heretofore-unseen details of the soft tissue that once surrounded the well-preserved bones.

Nanoscopic changes reveal cancer

A team of researchers in Chicago has developed a way to examine cell biopsies and detect never-before-seen signs of early-stage pancreatic cancer, according to a new paper.

Boosting protein NMR imaging speeds

A researcher believes he has found a quicker and more efficient approach to using SSNMR called paramagnetic relaxation-assisted condensed data collection, or PACC.

MRI shows brain atrophy pattern

Using special MRI methods, researchers have identified a pattern of regional brain atrophy in patients with mild cognitive impairment that indicates a greater likelihood of progression to Alzheimer's disease.

Intermediate viral particle crystallised

Scripps scientists create first crystal structure of an intermediate particle in virus assembly, providing fresh insight into how proteins aid in infection.

Avoiding invasive brain procedures

A clinical decision model which uses MR spectroscopy to help physicians differentiate between recurrent tumours and changes in the brain tissue due to radiation treatments, may help patients avoid invasive procedures and treatments.

Human DNA repair process recorded

A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis.

Brain activity possibly affected by sex

In a new fMRI study, researchers found differences among male and female groups on activation strength linked to verbal fluency.

Bleeding hearts revealed in scan

Images that for the first time show bleeding inside the heart after people have suffered a heart attack have been captured by scientists, in a new study.

New way to see cell molecules

Scientists describe a technique for imaging whole cells in liquid with a scanning transmission electron microscope (STEM).

Structure of key Ebola protein discovered

Researchers are a step closer to finding a way to counter the Ebola virus. A team of scientists has recently solved the structure from a key part of the Ebola protein known as VP35.

Enabling earlier thyroid cancer treatment

In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and...

Predicting anxiety treatment success

A new study reports that high levels of brain activity in an emotional centre called the amygdala reflect patients' hypersensitivity to anticipation of adverse events.

Predict effects of MS on optic nerve

Scientists report that an approach known as magnetic resonance diffusion tensor imaging allowed them to estimate three months in advance the chronic effects of inflammation of the optic nerve.

Differentiating colorectal polyps

Researchers compared narrow-band imaging (NBI) without high magnification to standard white light colonoscopy in differentiating colorectal polyps during real-time colonoscopy.

Immune cells intercepting parasites

Researchers may have identified one of the body's earliest responses to a group of parasites that causes illness in developing nations.

Dinosaurs were airheads

By using CT scans, the scientists were able to develop 3-D images of the dinosaur skulls that show a clearer picture of the physiology of the airways.
