Food wasted means money wasted which can be an expensive problem especially in homes with financial constraints. A new study from the Cornell Food and Brand Lab and the Getulio Vargas Foundation, shows that the top causes of food waste in such homes include buying too much, preparing in abundance, unwillingness to consume leftovers, and improper food storage.

"Fortunately," notes lead author Gustavo Porpino, PhD candidate at the Getulio Vargas Foundation and Visiting Scholar at the Cornell Food and Brand Lab, "most of the factors that lead to food waste, can be easily remedied by simple changes in food buying, preparing, and storing."

A new psoriasis drug, ixekizumab , has resulted in 40 percent of people showing a complete clearance of psoriatic plaques after 12 weeks of treatment and over 90 percent showing improvement.

A psychologist and an English professor have written a review of studies and concluded that pigs perform as well as or better than dogs on some tests of behavioral and cognitive sophistication, and they compare favorably to chimpanzees.

The review by Emory psychologist Dr. Lori Marino and visiting English Professor Christina M. Colvin, seeks to extrapolate results to deduce what we do and do not know about pigs. The areas they discuss include cognition, emotion, self-awareness, personality and social complexity.

They conclude that “pigs possess complex ethological traits similar … to dogs and chimpanzees.” For example, pigs:

The World Health Organization released its 2015 updated essential medicines list and for the first time included the progesterone contraceptive vaginal ring (CVR), a contraceptive safe and effective for lactating women in the postpartum period.

The progesterone CVR, developed by the Population Council, is an intravaginal ring that provides women who breastfeed at least four times a day with a contraceptive option as early as four weeks after giving birth. It can be used for up to a year for improved birth spacing.

Comparing the genomes of different species — or different members of the same species — is the basis of a great deal of modern biology because DNA sequences conserved across species are likely to be functionally important, while variations between members of the same species can indicate different susceptibilities to disease.

The central United States has undergone a dramatic increase in seismicity over the past 6 years. From 1973-2008, there was an average of 24 earthquakes of magnitude 3 and larger per year. From 2009-2014, the rate steadily increased, averaging 193 per year and peaking in 2014 with 688 earthquakes. So far in 2015, there have been 430 earthquakes of that size in the central U.S. region through the end of May.

There are many questions and misconceptions about what’s happening. How does the observed increase relate to oil and gas production activities? Does this connect to fracking—more formally known as hydraulic fracturing? What exactly is fracking? What are induced earthquakes?
