Dark matter is believed to account for 85 per cent of the Universe’s mass but has never been detected.   Scientists inferred its existence from gravitational effects of objects in space more than 75 years ago and it has become quite prominent in physics, for something that's never been seen or verified.

The international Virgo Consortium  say they can change that and have used a massive computer simulation showing the evolution of a galaxy like the Milky Way to “see” gamma-rays given off by dark matter.  They say their findings, published in Nature, could help NASA’s Fermi Telescope in its search for the dark matter and open a new chapter in our understanding of the Universe.

MIT engineers have outfitted cells with tiny “backpacks” that could allow them to deliver chemotherapy agents, diagnose tumors or become building blocks for tissue engineering. Michael Rubner, director of MIT’s Center for Materials Science and Engineering and senior author of a paper on the work that appeared online in Nano Letters on Nov. 5, said he believes this is the first time anyone has attached such a synthetic patch to a cell. 

The polymer backpacks allow researchers to use cells to ferry tiny cargoes and manipulate their movements using magnetic fields. Since each patch covers only a small portion of the cell surface, it does not interfere with the cell’s normal functions or prevent it from interacting with the external environment. 

A new study published in the journal of Minerva Cardioangiologica says that Pycnogenol, pine bark extract from the French maritime pine tree, reduces jetlag in passengers by nearly 50 percent. The two-part study, consisting of a brain CT scan and a scoring system, showed Pycnogenol lowered symptoms of jetlag such as fatigue, headaches, insomnia and brain edema (swelling) in both healthy individuals and hypertensive patients. Passengers also experienced minimal lower leg edema, a common condition associated with long flights. 

Research by the University of Warwick shows how death gave birth to the modern cult of celebrity as the sudden rise in the popularity of obituaries of unusual people in the 1700s provided people with the 18th Century equivalent of a celebrity gossip magazine. 

The skeleton of a 12,000 year-old Natufian Shaman has been discovered in northern Israel by archaeologists at the Hebrew University of Jerusalem. The burial is described as being accompanied by "exceptional" grave offerings - including 50 complete tortoise shells, the pelvis of a leopard and a human foot. The shaman burial is thought to be one of the earliest known from the archaeological record and the only shaman grave in the whole region.

A VHF radio interferometer system that was designed by Zhang GuangShu, et al of Cold and Arid Regions Environmental and Engineering Research Institute at Chinese Academy of Sciences was used to observe a cloud-to-ground lightning flash containing 19 strokes , revealing new characteristics of lightning.

The system in this study has five antennas that form an array in orthogonal directions, and an interactive graphic analysis procedure is used to remove the fringe ambiguities. The system error, which comes from frequency conversion, is reduced by phase detection through direct high frequency amplifying. By using the system, the whole progression process in time and space of a lightning flash can be continuously reconstructed at microsecond orders.
