For over 60 years now, the University of Liege Astrophysics and Geophysics Institute (IAGL) has been concerned with the study of comets. Again today, four of its researchers have just made a major discovery for the understanding of these celestial objects : a lot of extra heavy nitrogen detected in two comets suggests the presence of great quantities of complex organic molecules in them. The results obtained by the Liege team will be published in the next number of the international magazine, Science

It was worshipped by the ancient Egyptians, was said to keep vampires at bay, and is good for keeping you healthy.

Scientists from the University of Newcastle upon Tyne have now found the pungent herb garlic could win the costly worldwide war against slugs and snails as an environmentally friendly pesticide.

The findings are published in the current edition of the academic journal, Crop Protection*. Lead researcher Dr Gordon Port will speak about the effective alternatives

Within a tumor, chaos reigns: Nutrients are scarce, and healthy tissue is muscled out by cancerous tissue so aggressive that the tumor even sacrifices parts of itself to continue its relentless expansion.

It’s in this rough-and-tumble environment, controlled by a dizzying array of molecular signals, that researchers at the James P. Wilmot Cancer Center are grappling with a conundrum: Starve a tumor of oxygen, and the tumor should die – but without oxygen, pretty much all of today’

An astronomer from the Lawrence Livermore National Laboratory, in collaboration with an international team of researchers, have discovered that a neighboring galaxy — the Large Magellanic Cloud (LMC) — appears to have formed with an old stellar halo, similar to how our very own Milky Way formed.

The oldest and most metal-poor Milky Way stars form a spherical halo where they move about like atoms in a hot gas, which in turn prompts two major formation scenarios of our galaxy: extended hier

New approach may provide new way to diagnose, classify and treat diseases

UCLA researchers found a distinction in the gene expression of leprosy that accurately classified two different clinical forms of the disease. This is one of the first studies of its kind where genetic profiling distinguished between disease types, possibly leading to new ways to diagnose and treat all types of diseases.

The new UCLA study, published Sept. 12 in the journal Science, also identified gen

New nerve cells put fall foraging on fast track

The “senior moments” that herald old age, and the ability to forget where we put something we held in our hands just moments ago, give us humans much cause to envy a species like the black-capped chickadee.
Especially when fall is right around the corner.

Every autumn, the chickadee roams a territory covering tens of square miles, gathering seeds and storing them in hundreds of hiding places in trees and on the ground. Ove
