Dairy-free diets may put boys with autism at risk for thin bones

Results of an early study suggest that dairy-free diets and unconventional food preferences could put boys with autism and autism spectrum disorder (ASD) at higher than normal risk for thinner, less dense bones when compared to a group of boys the same age who do not have autism.

Adapting to pregnancy played key role in human evolution

The human spine evolved differently in males and females in order to alleviate back pressure from the weight of carrying a baby, according to research spearheaded at The University of Texas at Austin.

Human evolution in genetic fast lane

Countering a common theory that human evolution has slowed to a crawl or even stopped in modern humans, a new study examining data from an international genomics project describes the past 40,000 years as a time of supercharged evolutionary change, driven by exponential population growth and cultural shifts.

Genetic evidence that human evolution is speeding up

Researchers discovered genetic evidence that human evolution is speeding up – and has not halted or proceeded at a constant rate, as had been thought – indicating that humans on different continents are becoming increasingly different.

New genetic evidence supports theory migration from Siberia gave rise to native peoples of North and South America

Did a relatively small number of people from Siberia who trekked across a Bering Strait land bridge some 12,000 years ago give rise to the native peoples of North and South America?

Computer algorithm traces ancestry using anonymous DNA samples

A group of computer scientists, mathematicians, and biologists from around the world have developed a computer algorithm that can help trace the genetic ancestry of thousands of individuals in minutes, without any prior knowledge of their background.

Research highlights importance of starch in human beginnings

To think that world domination could have begun in the cheeks. That's one interpretation of a discovery, published online September 9 in Nature Genetics, which indicates that humans carry extra copies of the salivary amylase gene.

Convenience' foods save little time for working families at dinner

Two-income families in Los Angeles don't live so much in a fast food nation as they do in a Hamburger Helper hamlet on the edge of a packaged lettuce greenbelt, according to the first academic study to track American families moment by moment as they make dinner.

Why and when we started walking on two legs

Studying chimpanzees trained to use treadmills, a team of anthropologists has gathered new evidence suggesting our earliest apelike ancestors started walking on two legs because it required less energy than getting around on all fours.

Origin of bipedal walking

While no one has an authoritative answer, anthropologists have long theorized that early humans began walking on two legs as a way to reduce locomotor energy costs.

New evidence of very recent human adaptation

A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa.

Vitamin D deficiency remains an under-recognized problem in children

Many otherwise healthy children and adolescents have low vitamin D levels, which may put them at risk for bone diseases such as rickets.

Female reproductive function is influenced by childhood environment

This suggests there is a critical window of time from about 0-8 years of age that determines the rate at which girls physically mature and how high their reproductive hormone levels reach as adults.

Humanizing approaches to dementia care may extend patients' lives

Through an intensive comparative study of two nursing home units using contrasting approaches to dementia care for elders with severely disturbed behaviors, Central Michigan University professor of anthropology Athena McLean has found that "humanizing" approaches to dementia care may not only extend quality of life for patients, but also their length of life.

Study dispels myth that certain minority groups are genetically prone to diabetes

A study by U.S. and Australian researchers is helping dispel the 40-year-old "thrifty genotype theory," which purports that certain minority groups are genetically prone to diabetes.

Historical records detailing past attitudes towards prostitution, homosexuality and gender issues

Experts will examine a range of sources such as the UK's first-ever sex survey from the 1940s and documents detailing the life of Josephine Butler, the Victorian feminist who campaigned for the welfare of prostitutes.

Two more deaths from bird flu as Indonesia tries to track down souce of 'cluster' deaths

While Health officials in Indonesia are still trying to track down the source of infection in a cluster of six deaths in one family from H5N1 bird flu, tests show that two more people have also died of the same disease.

Mystery of evolutionary growth in hominid brain size

Forget the textbook story about tool use and language sparking the dramatic evolutionary growth of the human brain. Instead, imagine ancient hominid children chasing frogs. Not for fun, but for food.

Important skin color gene identified

With help from a common aquarium pet and a recently released online database of human genetic variation, a collaborative team of Penn State researchers has found what could be the most important skin color gene identified to date.

Study confirms that couples using natural family planning have intercourse just as frequently as couples using other methods

Couples who use fertility awareness-based methods of family planning have sex just as often as couples who use other contraceptive methods -- they just time it differently, according to a new Georgetown University Institute for Reproductive Health study to be published in a forthcoming edition of the Journal of Biosocial Science.
