First neurobiological evidence for theory of episodic memory

Almost everyone has experienced one memory triggering another, but explanations for that phenomenon have proved elusive. Now, University of Pennsylvania researchers have provided the first neurobiological evidence that memories formed in the same context become linked, the foundation of the theory of episodic memory.

Food4Me project to investigate potential of personalised nutrition

When the human genome sequence was launched in 2000, it introduced the possibility of personalisation in health care. Such personalisation can be applied to nutrition, a key health determinant, to create a diet tailored specifically for an individual, according to their individual physical and genetic make-up. Food4Me is a new, EU (FP7) funded project investigating the potential of this personalised nutrition.

Scientists discover cholesterol moves far slower within and between cells

Neutrons have shown the movement of cholesterol between and within cells takes far longer than previously thought. Findings could impact the treatment of a range of diseases linked to abnormal rates of cholesterol transfer.

Scientists identify new inherited form of Parkinson's disease

Scientists at the Helmholtz Zentrum München and the Technische Universität München working in cooperation with the Medical University of Vienna have identified a mutation associated with a inherited form of late-onset Parkinson's disease.

Researchers identify potential therapeutic target for ER-negative breast cancer

Using a new in vivo screening system, Whitehead Institute researchers have identified a protein in the serine biosynthesis pathway that is essential in estrogen receptor (ER)-negative breast cancer—a notoriously difficult disease to treat associated with low five-year survival rates.

Scientists find way to make copper-catalyzed click chemistry biocompatible

Biomolecular imaging can reveal a great deal of information about the inner workings of cells and one of the most attractive targets for imaging are glycans - sugars that are ubiquitous to living organisms and abundant on cell surfaces. Imaging a glycan requires that it be tagged or labeled. One of the best techniques for doing this is a technique called click chemistry.

Novel approach for preventing HIV infection

Scientists at Osel Inc. and the National Cancer Institute (NCI) have developed a new way to prevent HIV infection by genetically enhancing the ability of naturally occurring vaginal bacteria to block viral transmission.

Single TBI may accelerate Alzheimer's disease-like neurodegeneration

Years after a single traumatic brain injury (TBI), survivors still show changes in their brains. In a new study, researchers from the Perelman School of Medicine at the University of Pennsylvania suggest that Alzheimer's disease-like neurodegeneration may be initiated or accelerated following a single traumatic brain injury, even in young adults.

Researchers identify gene linked to muscle endurance

Researchers at the Perelman School of Medicine at the University of Pennsylvania have identified a gene for endurance, or more precisely, a negative regulator of it.

Study describes how hyperactivation of AMPK promotes neurodegeneration in HD

A new study describes how hyperactivation of AMP-activated protein kinase (AMPK) promotes neurodegeneration in Huntington's disease.

Scientists define structure of astrovirus that causes juvenile diarrhea

Rice University scientists have defined the structure -- down to the atomic level -- of a virus that causes juvenile diarrhea. The research may help direct efforts to develop medications that block the virus before it becomes infectious.

Nano-patterned plastic to advance stem cell research

Scientists have developed a novel plastic surface which overcomes the difficulties associated with growing adult stem cells. Standard surfaces have proved limited for growing large amounts and retaining the stem cells' useful characteristics. This discovery could lead to the creation of stem cell therapies for re-growing bone and tissue, and also for conditions such as arthritis. The study was carried out by Glasgow and Southampton universities.

Neutrons show how massive enzyme complexes inside cells control rate of sugar metabolism

Neutrons have shown how massive enzyme complexes inside cells might determine whether sugar is burnt for energy or stored as fat. These findings will improve understanding of diabetes and a range of metabolic diseases.

Study: 'The wave of death' may not indicate onset of brain death

The wave-shaped signal, which was previously dubbed 'the wave of death', had already been measured by researchers in Nijmegen in the brains of rats that had just been decapitated. The rats had already had electrodes implanted in their brains before the experiment.
