Rare genomic mutations found in 10 families with early-onset, familial Alzheimer’s disease
Mutations in only three genes – the amyloid precursor protein and presenilins 1 and 2 – have been established as causative for inherited, early-onset Alzheimer’s, accounting for about half of such cases.

‘Chase and run’ cell movement mechanism explains process of metastasis
A mechanism that cells use to group together and move around the body – called ‘chase and run’ - has been described for the first time by scientists at UCL.

A peptide to protect brain function
A structure called ‘the microtubule network’ is a crucial part of our nervous system. It acts as a transportation system within nerve cells, carrying essential proteins and enabling cell-to-cell communications.

Researchers identify a new mechanism of TB drug resistance
Pyrazinamide (PZA) – a frontline tuberculosis (TB) drug – is used for treating both drug susceptible and multi-drug resistant TB (MDR-TB) but resistance to PZA occurs frequently and can compromise treatment.

Bacterium that causes gum disease packs a one, two punch to the jaw
The newly discovered bacterium that causes gum disease delivers a one-two punch by also triggering normally protective proteins in the mouth to actually destroy more bone, a University of Michigan study found.

A potential new target to thwart antibiotic resistance
Bacteria in the gut that are under attack by antibiotics have allies no one had anticipated, a team of Wyss Institute scientists has found.

Non-invasive first trimester blood test reliably detects Down’s syndrome
New research has found that routine screening using a non-invasive test that analyses foetal DNA in a pregnant woman’s blood can accurately detect Down’s syndrome and other genetic foetal abnormalities in the first trimester.

Innate immunity: when DNA is out of place
In animal cells, DNA molecules are normally restricted to the cell nucleus and the mitochondria. When DNA appears outside these organelles – in the so-called cytosol - it most probably originates from a bacterial pathogen or a DNA virus.

New kind of antibiotic may be more effective at fighting tuberculosis, anthrax, and other diseases
Diseases such as tuberculosis, anthrax, and shigellosis could eventually be treated with an entirely new and more-effective kind of antibiotic, thanks to a team of scientists at Penn State University.

IU researchers focus on a brain protein and an antibiotic to block cocaine craving
A new study conducted by a team of Indiana University neuroscientists demonstrates that GLT1, a protein that clears glutamate from the brain, plays a critical role in the craving for cocaine that develops after only several days of cocaine use.

Team describes molecular detail of HIV’s inner coat, pointing the way to new therapies
A team led by researchers at the University of Pittsburgh School of Medicine has described for the first time the 4-million-atom structure of the HIV’s capsid, or protein shell.
