Why are most men taller than women? This age-old height difference persists to this day, according to research to be published in Proceedings B, a Royal Society journal, because taller than average men and shorter than average women were found to be more successful in attracting a mate and having children.
Dr Daniel Nettle of the Open University used data from 10,000 men and women born in Britain in one week in March 1958 and his study concluded that the taller the men were, the less likely
Routine parent-child bedsharing before 6 years of age appears to have no major impact on a child’s subsequent development or behavior — for better or for worse, the first long-term study of the practice reveals.
The researchers’ finding that there is “no evidence linking [early parent-child bedsharing], when engaged in responsibly, with any sort of problematic outcome” should give experts who caution against the practice reason to reconsider their advice, according to lead author Paul Oka
An enzyme whose activity is affected by alcohol may prove useful in identifying recent alcohol or marijuna use even though it does not seem to be a good marker for genetic predisposition to alcoholism, a new international study finds. The researchers also found that the activity level of the enzyme, adenylyl cyclase, steadily dropped in people who had abstained from drinking for days to weeks and was generally lower in people with a history of major depression, according to the study published in th
Full-time work for wives decreases the likelihood of divorce but does not improve marital happiness, Penn State researchers say.
Marital unhappiness frequently drives wives into the workplace, says Dr. Robert Schoen, the Hoffman Professor of Family Sociology and Demography at Penn State. Whether it be unhappy wives, husbands or both, unhappiness can play an important role in wives taking on full-time employment.

This is the first community study which specifically addresses the relationship between childhood abuse and vulnerability to illness with reliable methods. It derives from the collaboration of New Zealand (University of Dunnedin) and Italian (University of Modena) investigators coordinated by Professor Sarah Romans.
There have been many studies documenting adverse psychiatric consequences for people who have experienced childhood and adult sexual and physical abuse. These include posttraum
A report published today by the European Commission establishes for the first time the situation of women scientists in 30 European countries . The report is presented at a seminar opening today in Madrid and organised with the Spanish Presidency of the European Union on “Women and Science: promoting women in the scientific sector”.
The report, prepared by a group of national representatives known as the `Helsinki Group on Women and Science`, compiles national statistical profiles which ar
A new study shows that schools and many education programmes are failing to provide students with a basic understanding of evolution.
It is famously difficult to explain evolutionary principles without resorting to anthropomorphic or figurative language. Evolution ‘selects’ the fittest individuals; species ‘adapt’ to change. Both of these phrases are commonplace when explaining the very complex processes involved in evolution. However, this use of language implies that there is an agency o
Since the 30s of the 20th century, after two wars and revolutions, a lot of women have been joining scientific activities. At last, after centuries of fighting for their rights, women became considered full members of society. Women were welcome to work if they wished to – but only on equal terms with men. However, men and women were not to equalize in rights in terms of housekeeping obligations. It so happened that women did housekeeping, brought up children, and worked as hard as men. Initially, i
Women who hold back feelings of anger may end up more irate in the long run. According to new research, women experience a rebound effect when they suppress angry emotions, which can result in greater feelings of fury.
In the study, Judith Hosie and Alan Milne of the University of Aberdeen compared different methods of regulating anger and sadness in subjects exposed to footage from emotional films. The researchers instructed one group of men and women to express any feelings of anger brou
