A 19th-century historian traveling in southern Ohio later wrote about his first glimpse of Union Village, a Shaker community located near Harrison, Ohio: "When I caught sight of the first house, my opinion was confirmed that I was on the lands of the Shakers, for the …style of architecture, solid appearance and want of decorative art was before me.

A new study in the Journal of Marriage and Family found that serial cohabiters are less likely than single-instance cohabiting unions to result in marriage and, if serial cohabiters do marry, divorce rates are very high.

Daniel T. Lichter of Cornell University and Zhenchao of Ohio State University used data from the National Longitudinal Survey of Youth to track the experiences of serial cohabiters, or women who have cohabited with more than one partner.  

Fenfluramine, the appetite suppressant drug banned in the US in 1997 due to fears over its links to heart conditions, has been shown to have serious long-term effects. In a report published today in BMC Medicine, researchers have shown that people who stopped using fenfluramine eleven years ago had damaged heart valves up to seven years later.

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.
