Honest behavior is much like sticking to a diet - you have to be ready for temptation and consider the long-term consequences.

A recent paper says it is the first study to test how the two separate factors of identifying an ethical conflict and preemptively exercising self-control interact in shaping ethical decision-making.

In a series of experiments that included common ethical dilemmas, such as calling in sick to work and negotiating a home sale, the researchers found that two factors together promoted ethical behavior: Participants who identified a potential ethical dilemma as connected to other similar incidents and who also anticipated the temptation to act unethically were more likely to behave honestly than participants who did not.

Wide-scale population migrations and changes took place in Europe and Asia during the Bronze Age that shaped the demographic structure of present-day Europeans and Asians, as revealed by an analysis of 101 genomes from ancient Eurasian humans.

A new study published in this week’s Nature presents one of the largest studies of ancient DNA samples to date.  The research provides insights into the prevalence of certain traits such as skin color or lactose tolerance, as well as data relevant to the understanding the spread of Indo-European languages.

Women aged 50-69 years who attend mammography screening reduce their risk of dying from breast cancer by 40 percent compared to women who are not screened - according to a major international review of the latest evidence on breast cancer screening. Overall, women who are invited to attend mammography screening have a 23 percent risk reduction in breast cancer death (owing to some attending and some not), compared with women not invited by routine screening programs.

In the UK, this relative risk translates to around eight deaths prevented per 1,000 women regularly attending screening, and five deaths prevented per 1,000 women invited to screening.

Cancer has overtaken cardiovascular disease, which includes heart disease and stroke, as the UK's No 1 killer--but only among men, reveals research published online in the journal Heart.

Cardiovascular disease is still the most common cause of death among women, and kills more young women than breast cancer, the figures show.

The researchers used the latest nationally available data (2012-13) for each of the four UK countries and the Cardiovascular Disease Statistics 2014 report compiled for the British Heart Foundation (BHF) to quantify the prevalence of cardiovascular disease, and find out how it's treated, how much it costs, and how many deaths it causes.

U.S. government-issued dietary recommendations continue to evolve over time but a new paper by scholars claims that the main source of dietary information used by the U.S. Government’s 2015 Dietary Guidelines Advisory Committee (DGAC) is scientifically flawed because the underlying data are primarily informed by memory-based dietary assessment methods (M-BMs) (e.g. interviews and surveys).(1)

In an editorial response nutrition experts suggest that the purported flaws are well-appreciated by nutritional researchers and can be mitigated by using multiple data sources, resulting in valid data.(2)

The public has a bit of a cultural schism about elections. Everyone says they want more diversity of candidates but an actual primary race is a sign of weakness. In the United States of America, Democrats are trumpeting the fact that they picked their candidate for 2016 back in 2013 and ridiculing Republicans because they have a dozen contenders. And we are told that if polls are too accurate, people will not bother to vote, but if they are not accurately predicting the winner of an election that has not occurred, it is a failure.
