Bound neutrons pave way to free ones
— 8 Feb 2011 17:21 | PhysicsA study of bound protons and neutrons conducted at the Department of Energy's Thomas Jefferson National Accelerator Facility has allowed scientists, for the first time, to extract information…
First evidence for a spherical magnesium-32 nucleus
— 3 Feb 2011 17:30 | PhysicsElements heavier than iron come into being only in powerful stellar explosions, supernovae. During nuclear reactions all kinds of short-lived atomic nuclei are formed, including more…
A possible cause of Parkinson's disease discovered
— 1 Feb 2011 21:33 | Health'Nucleolus,' or small nucleus, is the term coined by early biologists for the tiny structure within the nucleus which they saw under the microscope. In this structure within the nucleus,…
CSHL study finds that 2 non-coding RNAs trigger formation of a nuclear subcompartment
— 19 Dec 2010 23:14 | BiologyThe nucleus of a cell, which houses the cell's DNA, is also home to many structures that are not bound by a membrane but nevertheless exist as distinct compartments. A team of Cold…
New microscope reveals ultrastructure of cells
— 20 Nov 2010 10:43 | BiologyFor the first time, there is no need to chemically fix, stain or cut cells in order to study them. Instead, whole living cells are fast-frozen and studied in their natural environment.…
New characteristics of premature ageing protein discovered at Stevens
— 17 Nov 2010 09:42 | HealthDr Joseph Glavy at Stevens Institute of Technology studies the smallest and most basic elements of life. The Assistant Professor of Chemical Biology runs the Glavy Lab, where advanced…
Change in temperature uncovers genetic cross talk in plant immunity
— 16 Nov 2010 13:24 | BiologyLike us, plants rely on an immune system to fight off disease. Proteins that scout out malicious bacterial invaders in the cell and communicate their presence to the nucleus are important…
Immune cells deploy traps to catch and kill pathogens
— 26 Oct 2010 13:20 | HealthA new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unravelling and using the chromatin (DNA and its associated proteins) contained in the cells'…
Isotope near 'doubly magic' tin-100 flouts conventional wisdom
— 23 Oct 2010 16:27 | PhysicsTin may seem like the most unassuming of elements, but experiments performed at the Department of Energy's Oak Ridge National Laboratory are yielding surprising properties in extremely…
Scientists find signals that make cell nucleus blow up like a balloon
— 15 Oct 2010 12:57 | BiologySize matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different…
