Older people without dementia but who are starting to have memory and thinking problems may have a lower risk of dying from cancer, according to a paper in Neurology. People with dementia are less likely to develop cancer also.

The study involved 2,627 people age 65 and older in Spain who did not have dementia at the start of the study. They took tests of memory and thinking skills at the start of the study and again three years later, and were followed for an average of almost 13 years. The participants were divided into three groups: those whose scores on the thinking tests were declining the fastest, those whose scores improved on the tests, and those in the middle.

Speculation goes that part of the problem for the RMS Titanic, which set out on its maiden voyage 102 years ago today, was bad luck; an exceptional number of icebergs.

Not really, according to a new analysis. There are more icebergs now.

Previously it had been suggested that the seas which sank the famous cruise ship had an exceptional number of icebergs, caused by lunar or solar effects, but using data on iceberg locations dating back to 1913 – recorded to help prevent a repeat of the Titanic – they have shown that 1912 was a significant ice year but not extreme.

The reconstruction of an extinct meat-eating marsupial's skull, Nimbacinus dicksoni, suggests that it may have had the ability to hunt vertebrate prey exceeding its own body size, according to results published April 9, 2014, in the open access journal PLOS ONE by Marie Attard from the University of New England together with colleagues from the University of New South Wales.

Growing agave and other carefully chosen plants amid photovoltaic panels could allow solar farms not only to collect sunlight for electricity but also to produce crops for biofuels, at least according to computer models.

High total and saturated fat intake were associated with greater risk of estrogen receptor- and progesterone receptor-positive (ER+PR+) breast cancer, and human epidermal growth factor 2 receptor-negative (HER2-) disease, according to a new study in the Journal of the National Cancer Institute.

James Lovelock, the Godfather of Global Warming, says we are doomed and the only recourse left is to retreat to climate-controlled cities. Others claim we can solve the problem if we just shut off all of the power plants. Others contend we simply need to stop building them.
