Study Shows Men Won’t Be Losing Their Y Chromosome Anytime Soon

Finally, some good news for men, as a new study in PLOS Genetics has found that the human race may not be losing the Y chromosome after all. Some popular theories have posited that the male sex chromosome is destined to diminish and disappear.

The Y chromosome has lost 90 percent of the genes it once shared with the X chromosome, and some scientists have speculated that the Y chromosome will disappear in less than 5 million years, said study author Melissa A. Wilson Sayres, a post-doctoral evolutionary biologist at the University of California, Berkeley.

Some mammal species have lost their Y chromosome, yet still have the ability to sexually reproduce viable offspring fueling suspicions that the chromosome may not be essential in humans.

Our study demonstrates that the genes that have been maintained, and those that migrated from the X to the Y, are important, and the human Y is going to stick around for a long while, Wilson Sayres said.

Based the Y chromosome analysis of 16 men, researchers found genetic evidence of natural selection maintaining the chromosomes content, which has been shown to mostly play a role in male fertility. The researchers said the Y chromosomes diminutive size is a sign that it is stripped down to its 27 essential genes.

Melissas results are quite stunning. They show that because there is so much natural selection working on the Y chromosome, there has to be a lot more function on the chromosome than people previously thought, said co-author Rasmus Nielsen, UC Berkeley professor of integrative biology.

He added that the study will help advance estimates of humans evolutionary history that are done based on an analysis of the Y chromosome.

Melissa has shown that this strong negative selection natural selection to remove deleterious genes tends to make us think the dates are older than they actually are, which gives quite different estimates of our ancestors history, Nielsen said.

DNA Links Executed Convict to 1984 Triple Murder

Posted: at 3:43 pm

An Iowa man who was executed in Missouri for the 1987 murder of a 12-year-old girl has now been linked to an unsolved triple homicide three years earlier, investigators announced Friday.

New DNA evidence implicates Andrew Six in the 1984 bludgeoning deaths of 20-year-old Justin Hook Jr.; Hook's fiancee, 19-year-old Tina Lade; and Hook's mother, 41-year-old Sara Link, according to the Iowa Division of Criminal Investigation. Analysts did testing on evidence recovered from the inside of Lade's jeans to develop a profile, which matched Six's DNA.

Missouri authorities executed Six by lethal injection in 1997 for the kidnapping and murder of 12-year-old Kathy Allen. Six and his uncle kidnapped the girl from her family's trailer in Ottumwa, a city in southeast Iowa, then slit her throat and dumped her body in northern Missouri.

Retired DCI supervisor Sam Swaim said that Six had long been a suspect in the 1984 triple homicide, but that investigators could not come up with enough evidence. He said that he was happy that scientific evidence has finally linked Six to the crime, but wishes Six had been caught earlier.

"I regret that we didn't get that case solved. That would have saved Kathy Allen's life," he said in a phone interview.

Hook's body was found outside his burned-out trailer in rural Drakesville, a sleepy town of 200 people near the Missouri border, in April 1984. When authorities tried to notify Hook's mother at her home in Farmington, they learned that she was missing.

Days later, a farmer found her body on a hilly, wooded section of his home near Eldon, about 15 miles northeast of Drakesville. Two days later, police dogs found the body of Lade in a ravine a half-mile from where Link's body was recovered. Investigators said all three had been killed by blows to the head, and that the deaths were related and probably happened around the same time.

The discovery of the bodies day after day shook a rural area that typically sees little violent crime. Friends said Hook had given Lade, of Ottumwa, an engagement ring days before their deaths on the birthday they shared, when she turned 19 and he turned 20.

"I'm glad they did the work that they've done," said Cynthia Moyes of Coralville, the sister of Hook and daughter of Link. "It provided some closure."

Great Whites May Live Much Longer Than Previously Thought

Posted: at 3:43 pm

January 9, 2014

Great white sharks have always been considered one of the longer living fish, but a new study in the journal PLOS ONE has found that they actually live much longer than previously believed.

Using a radiocarbon analysis, study researchers from the Woods Hole Oceanographic Institution (WHOI) and National Oceanic and Atmospheric Administration (NOAA) discovered that male great whites can live up to 73 years and females can live up to 40.

Our results dramatically extend the maximum age and longevity of white sharks compared to earlier studies, said study author Li Ling Hamady, a Joint Program student at WHOI. Understanding longevity of the species, growth rate, age at sexual maturity, and differences in growth between males and females are especially important for sustainable management and conservation efforts.

The conventional method to determine the age of a fish relies on analyzing growth increments in mineralized tissue like ear bones, vertebrae, and fin rays. As these tissues grow during a fishs life, they form annual rings in the process, comparable to the growth rings in trees.

The problem with using this method in great whites is the oscillating light and dark banding patterns in shark vertebrate can be thin and less distinct than in other species. The bands also dont necessarily signify annual growth.

Ageing sharks has traditionally relied on counting growth band pairs, like tree rings, in vertebrae with the assumption that band pairs are deposited annually and are related to age, said study author Lisa Natanson, a fisheries biologist at NOAAs Northeast Fisheries Science Center (NEFSC).

In many cases, this is true for part or all of a species life, but at some point growth rates and age are not necessarily in sync. Growth rates slow as sharks age. Deposition rates in vertebrae can change once the sharks reach sexual maturity, resulting in band pairs that are so thin they are unreadable. Age is therefore frequently underestimated.

Based on these growth-band methods, previous studies identified the oldest white shark individuals from the southwestern Pacific Ocean as 22 years old and the western Indian Ocean as 23 years old.

In the new study, the researcher team decided to take advantage of a unique human activity: thermonuclear device testing that took place during the 1950s and 1960s. Radioactive carbon from the tests was eventually mixed into the ocean and was integrated into the tissues of marine organisms living at the time. The distinct radiocarbon signature gave the study team a specific point in time that could be identified in the vertebra layers essentially a time stamp to help resolve the age of an organism.
