 By looking at signature chemical differences in the DNA of various immune cells called leukocytes, scientists have developed a way to determine their relative abundance in blood samples. The relative abundance turns out to correlate with specific cancers and other diseases, making the technique, described in two recent papers, potentially valuable not only for research but also for diagnostics and treatment monitoring.

Astronomers report a baffling discovery never seen before: An extraordinary amount of dust around a nearby star has mysteriously disappeared.
A group of US researchers has produced a robotic set of legs which they believe is the first to fully model walking in a biologically accurate manner.
The effect of spaceflight on a microscopic worm -- Caenorhabditis elegans (C. elegans) -- could help it to live longer.
The combination of melting sea ice and global atmospheric warming are contributing to the high rate of warming in the Arctic, where temperatures are increasing up to four times faster than the global average, a new University of Melbourne study has shown.
The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments.
San Diego State University researchers at the Donald P. Shiley BioScience Center may have found the secret to helping the immune system fight off the flu before it gets you sick.
A team of scientists has created an “MRI” of the Sun’s interior plasma motions, shedding light on how it transfers heat from its deep interior to its surface. The result, which appears in the journal the Proceedings of the National Academy of Sciences, upends our understanding of how heat is transported outwards by the Sun and challenges existing explanations of the formation of sunspots and magnetic field generation.
For the first time, researchers at Aalto University in Finland have located where the sounds associated with the northern lights are created. The auroral sounds that have been described in folktales and by wilderness wanderers are formed about 70 meters above the ground level in the measured case.
Observations with CSIRO's Australia Telescope Compact Array have confirmed that astronomers have found the first known "middleweight" black hole.
A volcanic eruption around 579 million years ago buried a 'nursery' of the earliest-known animals under a Pompeii-like deluge of ash, preserving them as fossils in rocks in Newfoundland, new research suggests.
