Injecting a specific gene directly
into the brain may offer a potential new therapy for halting the progress of
Alzheimer’s disease, especially when treated at an early stage, a new study has
claimed. Scientists from Imperial College London in the UK used a type of
modified virus to deliver a gene to brain cells in mice. Previous studies by
the same team suggest this gene, called PGCI – alpha, may prevent the formation
of a protein called amyloid beta peptide in cells in the lab. Amyloid beta
peptide is the main component of amyloid plaques, the sticky clumps of protein
found in the brains of people with Alzheimer’s disease. These plaques are
thought to trigger the death of brain cells. Worldwide 47.5 million people are
affected by dementia – of which Alzheimer’s is the most common form,
researchers said. There is no cure, although current drugs can help treat the
symptoms of the disease. Other researchers said this new findings may one day
provide a method of preventing the disease, or halting it in the early stages. Although
these findings are very early they suggest this gene therapy may have potential
therapeutic use for patients.

After 2 Millennia, 3D Tech Brings Ancient House To Life
Researchers have used 3D technology
to reconstruct a house in Pompeii, the ancient town city wiped out by the eruption
of a volcano two millennia ago, to show what life may have been like for its
people. By combining traditional archaeology with 3D technology, researchers at
Lund University is Sweden have managed to complete the detailed reconstruction
of a wealthy man’s bungalow. In 1980, the Pompeii city curator invited the international
research community to help document the ruins before they suffered further
damage. Thus began the Swedish Pompeii Project at the Swedish Institute in Rome
in 2000. The town-city, destroyed in AD 79, was scanned during field work in
2011-2012. Among other things, the researchers have uncovered floor surfaces
from AD 79, performed detailed studies of the building development through
history, cleaned and documented three large wealthy estates, a tavern, a
laundry, and several gardens. In one garden, they discovered that some of the
taps of a fountain were on at the time of the eruption. In a shop, they found
three intact windows (made of translucent crystalline gypsum) from ancient
Rome.
