Researchers from UCL have demonstrated how an interplay between nutrition, metabolism and immunity is involved in the process of ageing.

The two new studies, supported by the Biotechnology and Biological Sciences Research Council (BBSRC), could help to enhance our immunity to disease through dietary intervention and help make existing immune system therapies more effective. As we age our immune systems decline. Older people suffer from increased incidence and severity of both infections and cancer. In addition, vaccination becomes less efficient with age. (more…)

Blocking cells’ movement to stop the spread of cancer

Insights into how cells move through the body could lead to innovative techniques to stop cancer cells from spreading and causing secondary tumours, according to new UCL research.

Scientists discovered that cells can change into an invasive, liquid-like state to readily navigate the narrow channels in our body. This transformation is triggered by chemical signals, which could be blocked in order to stop cancer cells from spreading. (more…)

Researchers at Berkeley Lab’s Molecular Foundry Create First Soluble 2D Supramolecular Organic Frameworks

Supramolecular chemistry, aka chemistry beyond the molecule, in which molecules and molecular complexes are held together by non-covalent bonds, is just beginning to come into its own with the emergence of nanotechnology. Metal-organic frameworks (MOFs) are commanding much of the attention because of their appetite for greenhouse gases, but a new player has joined the field – supramolecular organic frameworks (SOFs). Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have unveiled the first two-dimensional SOFs that self-assemble in solution, an important breakthrough that holds implications for sensing and separation technologies, energy sciences, and, perhaps most importantly, biomimetics.

Berkeley Researchers Develop Technique For Imaging Individual Carbon Nanotubes

Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now.

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have developed a technique that can be used to identify the structure of an individual carbon nanotube and characterize its electronic and optical properties in a functional device.

MU Research Sheds Light on Nerve Regeneration Following Spinal Cord Injury

COLUMBIA, Mo. – Fish, unlike humans, can regenerate nerve connections and recover normal mobility following an injury to their spinal cord. Now, University of Missouri researchers have discovered how the sea lamprey, an eel-like fish, regrows the neurons that comprise the long nerve “highways” that link the brain to the spinal cord. Findings may guide future efforts to promote recovery in humans who have suffered spinal cord injuries.

“There is a lot of attention to why, following a spinal cord injury, neurons regenerate in lower vertebrates, such as the sea lamprey, and why they don’t in higher vertebrates, such as humans,” said Andrew McClellan, professor of biological sciences in the College of Arts and Science and director of the UM Spinal Cord Injury Research Program (SCIRP).

Using ultra-fast laser pulses, a team of researchers led by UA assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds containing nitrogen-vacancy centers – promising candidates for a variety of technological advances such as quantum computing.

A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers – defects in which two adjacent carbon atoms in the diamond’s crystal structure are replaced by a single nitrogen atom and an empty gap.

Method makes it easier to separate useful stem cells from ‘problem’ ones for therapies

UCLA study IDs small molecule that destroys potentially dangerous cells

Pluripotent stem cells can turn, or differentiate, into any cell type in the body, such as nerve, muscle or bone, but inevitably some of these stem cells fail to differentiate and end up mixed in with their newly differentiated daughter cells.

Because these remaining pluripotent stem cells can subsequently develop into unintended cell types — bone cells among blood, for instance — or form tumors known as teratomas, identifying and separating them from their differentiated progeny is of utmost importance in keeping stem cell–based therapeutics safe.

ANN ARBOR — Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.

The aggregation of these proteins, called metal-associated amyloids, is associated with Alzheimer’s disease and other neurodegenerative conditions. (more…)
