A photograph of John F. Kennedy assassin Lee Harvey Oswald holding a rifle and a copy of The Militant communist paper in 1963 is authentic, says Dartmouth Computer Scientist Hany Farid, a pioneer in the field of digital forensics, who digitally analyzed the iconic image of Oswald pictured in a backyard a few months before the assassination.
Oswald and various conspiracy theorists claimed that the incriminating photo was a fake, stating the lighting and shadows were inconsistent, but after analyzing the photo with modern-day forensic tools, Farid says the photo almost certainly was not altered.
Experts long ago said that this image had not been tampered with, but a surprising number of skeptics still assert that there was a conspiracy.
Everybody understands that good parents have to lay down rules for their children as they grow up. However, too many rules can be a bad thing, says a new report in Current Directions in Psychological Science.
According to the authors, numerous studies have found that in Western countries, when parents are too strict with their children, they can impede their psychological development. It has also been suggested that this effect may not be as strong in East Asian countries — researchers have posited that certain aspects of East Asian culture may make children more accepting of their parents' intrusive behavior.
Scientists have successfully differentiated human embryonic stem cells (hESC) into major cell types of lung epithelial tissue, a technique which could provide an alternative to lung transplants for patients with lung injury due to chronic pulmonary disease and inherited genetic diseases such as cystic fibrosis.
Hormones called androgens are considered important in the development of masculine characteristics like aggression and strength and some believe that prenatal androgens affect finger length during development in the womb.
High levels of androgens, such as testosterone, increase the length of the fourth finger in comparison to the second finger. Some archaeologists and anthropologists are using finger ratios as an indicator of the levels of exposure to the hormone and recently compared this data with social behavior in primate groups.
While more than half the academic life science researchers responding to a 2007 survey indicated having some relationship with private industry, the prevalence of such relationships – particularly direct funding for research studies – appears to be dropping.
The Results of a survey, appearing in the November/December 2009 issue of Health Affairs,
also suggest that interest in commercial applications of research appears to be growing, even among investigators without industry funding. The new study is a follow-up to 1985 and 1995 surveys by members of the same team.
Capitalism isn't perfect. Because business, like science, is about excellence and not fairness some people are going to make more money than other people. Some are going to be better at marketing and some are even going to cheat.
A professor in chemical engineering with no private sector experience has figured out how to redo capitalism so it works great - in a numerical model.
