While science tries to understand the stuff dreams are made of, humans, from cultures all over the world, continue to believe that dreams contain important hidden truths, according to newly published research. 

In six different studies, researchers surveyed nearly 1,100 people about their dreams. "Psychologists' interpretations of the meaning of dreams vary widely," said Carey Morewedge, an assistant professor at Carnegie Mellon University and the study's lead author. "But our research shows that people believe their dreams provide meaningful insight into themselves and their world."

Six studies published in the past year by a Cornell researcher add to growing evidence that an apple a day -- as well as daily helpings of other fruits and vegetables -- can help keep the breast-cancer doctor away. 

In one of his recent papers, published in the Journal of Agricultural and Food Chemistry (57:1), Rui Hai Liu, Cornell associate professor of food science and a member of Cornell's Institute for Comparative and Environmental Toxicology, reports that fresh apple extracts significantly inhibited the size of mammary tumors in rats -- and the more extracts they were given, the greater the inhibition. 

Contrary to the TV sitcom where the wife experiencing strong labor pains screams at her husband to stay away from her, women rarely give birth alone. Today, there are typically doctors, nurses and husbands in hospital delivery rooms, and sometimes even other relatives and friends. Midwives often are called on to help with births at home.  

Assisted birth has likely been around for millennia, possibly dating as far back as 5 million years ago when our ancestors first began walking upright, according to University of Delaware paleoanthropologist Karen Rosenberg.  She says that social assistance during childbirth is just one aspect of our evolutionary heritage that makes us distinctive as humans.

U.S. intelligence officials have spent more than seven years searching for Osama bin Laden but UCLA geographers say that, if he is still alive, they have a good idea of where he was at the end of 2001 — and perhaps where he has been in the years since.

What happens when a big chunk of your genome is accidentally copied? Bad things could obviously happen when when sudden and dramatic changes are made to your genome (which is why we wear sunblock on the beach and lead shields when getting X-rayed). Recent studies have found that accidental duplications in the genome (which can change the copy number of sets of genes) are involved in a growing list of diseases, including autism, psoriasis, and susceptibility to AIDS. And yet we also know that big DNA duplications aren't always harmful, because we can find ancient duplications in our genomes that harbor genes filling useful roles in our physiology.

How frequently do these large duplications arise, and what role have they played in human evolution? A group led by Evan Eichler, at the University of Washington, aided by the DNA sequencing powerhouse of the Genome Sequencing Center at Washington University (in St. Louis - not the same place as the University of Washington!), has studied these questions by looking for big, duplicated chunks in our closest relatives - the great apes. Their results show that big DNA duplications have probably played an important role in the evolution of our species.

The Archaeopteryx is experiencing a phoenix-like reascent to fossil celebrity status.  The disovery of this clearly birdlike dinosaur in 1861 lent ethos to Darwin’s brand new Theory of Evolution.  In December, the Thermopolis, WY archaeopteryx fossil was escorted to the Stanford Synchrotron Radiation Lightsource laboratory for synchrotron X-ray analysis.  According to researcher Uwe Bergmann, "What you normally can't see are the chemical elements from the original organism that might still be present in the fossil. Using X-ray fluorescence imaging, we can bring these elements to light, getting a better look at the fossil and learning more about the original animal.”
