The mysterious spotted green pigeon (Caloenas maculata) was a relative of the dodo, according to scientists who have examined its genetic make-up. The authors say their results, published in the open access journal BMC Evolutionary Biology, support a theory that both birds are descended from 'island hopping' ancestors.

This is the first study to investigate cerebral palsy over such a broad range of family relationships.
Cerebral palsy is the most common cause of physical disability in children, affecting approximately two in 1,000 live births in the developed world (and many more elsewhere). It originates from damage to the 'immature' brain and several risk factors in pregnancy have been identified such as preterm delivery, abnormal growth, exposure to infection and lack of oxygen at birth.
Dr Zulfiqar Bhutta, Robert Harding Chair in global child health and policy and Co-Director of the Centre for Global Child Health at the Hospital for Sick Children, Toronto believes that criminal sanctions are necessary to deter growing research misconduct.
He says the fact that research fraud is common is no longer news, but a review by PubMed in 2012 found that 67% of research article retractions were "attributable to scientific misconduct, including fraud or suspected fraud".
WEST LAFAYETTE, Ind. – Researchers from Purdue University and the University of Nebraska-Lincoln have discovered a soybean gene whose mutation affects plant stem growth, a finding that could lead to the development of improved soybean cultivars for the northern United States.
A significant percentage of completed drug clinical trials, especially those funded by industry, are not disclosed to the public, years after being completed—a trend that "threatens the validity of the clinical research literature in the U.S.," according to a study led by a Boston University School of Public Health (BUSPH) researcher.
We've all heard the stereotype: Women like to talk. We bounce ideas off each other about everything from career moves to dinner plans. We hash out big decisions through our conversations with one another and work through our emotions with discussion.
At least, that's what "they" say. But is any of it actually true? A new study from Northeastern University professor David Lazer's lab says it isn't that simple.
For bees and the flowers they pollinate, a compatible tongue length is essential to a successful relationship. Some bees and plants are very closely matched, with bee tongue sized to the flower depth. Other bee species are generalists, flitting among flower species to drink nectar and collect pollen from a diverse variety of plants. Data on tongue lengths can help ecologists understand and predict the behavior, resilience and invasiveness of bee populations.
Fewer Americans are having strokes and those who do have a lower risk of dying from them finds a new study led by Johns Hopkins Bloomberg School of Public Health researchers.
Despite the belief that early HIV infection presents with a well recognized flu-like syndrome, most physicians are unable to use clinical skills to differentiate those who should and should not be tested for HIV infection, according to a study published July 15 in Journal of the American Medical Association (JAMA).
In an analysis that included more than 480,000 patients who underwent elective noncardiac surgery, a history of stroke was associated with an increased risk of major adverse cardiovascular events and death, particularly if time elapsed between stroke and surgery was less than 9 months, according to a study in the July 16 issue of JAMA.
A study that included about 15,000 physicians found that they were more likely to be registered as an organ donor compared to the general public, according to a study in the July 16 issue of JAMA.
PROVIDENCE, R.I. – In a recent study, researchers at Rhode Island Hospital found that fear of being rejected because of one's appearance, as well as rejection sensitivity to general interpersonal situations, were significantly elevated in individuals with Body Dysmorphic Disorder (BDD). These fears, referred to as personal rejection sensitivity and appearance-based rejection sensitivity, can lead to diminished quality of life and poorer mental and overall health.
ANN ARBOR, Mich. -- The number of younger men diagnosed with prostate cancer has increased nearly 6-fold in the last 20 years, and the disease is more likely to be aggressive in these younger men, according to a new analysis from researchers at the University of Michigan Comprehensive Cancer Center.
Typically, prostate cancer occurs more frequently as men age into their 70s or 80s. Many prostate cancers are slow-growing and many older men diagnosed with early stage prostate cancer will end up dying from causes other than prostate cancer.
DURHAM, N.C. -- In the U.S., couples with daughters are somewhat more likely to divorce than couples with sons. Many scholars have read those numbers as evidence that daughters cause divorce.
But new research from Duke University suggests something quite different may be at play: Girls may be hardier than boys, even in the womb, and may be better able to survive pregnancies stressed by a troubled marriage.
COLUMBUS, Ohio – A new study of the anti-sweatshop campaigns of the 1990s reveals which companies are most likely to become targets of anti-corporate activists.
Researchers found that companies tended to attract the attention of labor activists if they were large, had prominent brand images, or had good corporate reputations. When combined, these factors were especially important.
