CU women’s Jeffery Gains Conference, National Honors
Dec 17th
Jeffery was named the espnW National Player of the Week and Pac-12 Conference Player of the Week for the week of Dec 10-16. She also received national and Pac-12 Player of the Week honors from collegesportsmadness.com.
A 5-foot-10-inch guard from Colorado Springs, Colo., Jeffery averaged 18 points, 9.0 rebounds and 4.5 assists while shooting 46 percent from the field and 80 percent from the free-throw line in wins over Denver and No. 8 ranked Louisville last week.
Against Louisville she had a game-high and personal season-best 22 points along with seven rebounds, four assists and one steal as the Buffaloes claimed their first win over a top-10 opponent since defeating No. 5 Stanford in the 2002 NCAA Sweet 16. Jeffery recorded season highs from the 3-point line (2-of-5) and the foul line (8-10) as she became the 16th player in team history to reach 1,300 career points (1,317).
Jeffery had 14 points, 11 rebounds, five assists and two steals in the road win over Denver on Dec. 11. She notched her second double-double of the season, and 22nd of her career, tying Sandy Bean (1978-82) for fifth on CU’s all-time list.
The two wins allowed Colorado to remain one of only eight unbeaten teams in NCAA Division I (9-0) and crack the Associated Press poll this week at No. 25 for the first time since Jan. 14, 2008.
Jeffery’s Pac-12 Player of the Week honor is her second, as she received the same award on Dec. 5, 2011. It’s Colorado’s fifth overall Pac-12 weekly award and fourth this year. Arielle Roberson is a three-time winner of Pac-12 Freshman of the Week so far this season.
Colorado will return to the court on Saturday, Dec. 22, by hosting Utah Valley at 1:30 p.m. at the Coors Events Center.

Ron Baird's BLACK WIND a new thriller crime novel quality fiction
May 26th
Twenty seconds in a young man’s life has followed him like the shadow of a curse for 27 years. Did he crack under pressure or was it simply good reflexes? Aaron Hemingway still doesn’t know and nobody ever told him because the Army had buried it in a black hole.
But in an ironic twist of karma, it was those close to Aaron who paid the price. He sometimes questioned whether the two were connected, but after his 14-year-old daughter was taken hostage by a murder suspect and then watched three men die in her bloody rescue, that was pretty much the end of the argument Aaron, a former Denver cop and newspaper reporter.
So he became a recluse, avoiding people he cared about to protect them. But after three years of that, he was ready to eat his gun. Then an old friend called and offered him a temporary job as a small town deputy marshal. Knowing what was at risk, he nevertheless took the job.
Surprisingly, things seemed to be going well, including his handling of a couple of situations that were ripe for disaster. Then, in an unprovoked but not random attack, his dog was killed and his women friend was left in a coma with a gunshot wound to the head.
Aaron discovered the identity of the man behind the attack and, breaking a vow he made after Vietnam to never kill again unless in self-defense or to protect the innocent, he swore vengeance against the man. He only saw three outcomes: he would be killed, he would succeed and be arrested or he would get away with murder. In the Malpais lava fields of western New Mexico, he found that things are not always that simple.

ANCIENT BIPEDAL HOMINID DUBBED ‘NUTCRACKER MAN’ PREFERRED GRASS TO NUTS, NEW STUDY FINDS
May 2nd
The hominid, known as Paranthropus boisei, ranged across the African landscape more than 1 million years ago and lived side-by-side with direct ancestors of humans, said University of Colorado Boulder anthropology Professor Matt Sponheimer, a study co-author. It was long assumed Paranthropus boisei favored nuts, seeds and hard fruit because of its huge jaws, powerful jaw muscles and the biggest and flattest molars of any known hominid in the anthropological record, he said.
In the last several years, research on the wear marks of teeth from Paranthropus boisei by other research teams has indicated it likely was eating items like soft fruit and grasses, said Sponheimer. That evidence, combined with the new study that measured the carbon isotopes embedded in fossil teeth to infer diet, indicates the rugged jaw and large, flat tooth structure may have been just the ticket for Paranthropus boisei to mow down and swallow huge amounts of grasses or sedges at a single sitting, he said.
“Frankly, we didn’t expect to find the primate equivalent of a cow dangling from a remote twig of our family tree,” said Sponheimer.
Published in the May 2 issue of the Proceedings of the National Academy of Sciences, the study was led by University of Utah Professor Thure Cerling. Other authors included Emma Mbua, Frances Kirera, Fredrick Manthi and Meave Leakey from the National Museums of Kenya, Fredrick Grine from Stony Brook University in New York and Kevin Uno from the University of Utah.
“Fortunately for us, the work of several research groups over the last several years has begun to soften prevailing notions of early hominid diets,” said Sponheimer. “If we had presented our new results at a scientific meeting 20 years ago, we would have been laughed out of the room.”
For the new study, the researchers removed tiny amounts of enamel from 22 Paranthropus boisei teeth collected in central and northern Kenya, each of which contained carbon isotopes absorbed from the types of food eaten during the lifetime of each individual. In tropical environments, virtually all trees and bushes — including fruits and leaves — use the so-called C3 photosynthetic pathway to convert sunlight into energy, while savannah grasses and some sedges use the C4 photosynthetic pathway.
The isotope analysis indicated Paranthropus boisei individuals were much bigger fans of C4 grasses and sedges than C3 trees, shrubs and bushes. The results indicated the collective diet of the 22 individuals averaged about 77 percent grasses and sedges for a period lasting at least 500,000 years, said Sponheimer.
The research team also compared the carbon isotope ratios of Paranthropus teeth with the teeth of other grazing mammals living at the same time and in the same area, including ancestral zebras, hippos, warthogs and pigs. The results indicated those mammals were eating primarily C4 grasses, virtually identical to Paranthropus boisei. “They were eating at the same table,” said Cerling.
Paranthropus was part of a line of close human relatives known as australopithecines that includes the famous 3-million-year-old Ethiopian fossil Lucy, seen by some as the matriarch of modern humans. Roughly 2.5 million years ago, the australopithecines are thought to have split into the genus Homo — which produced modern Homo sapiens — and the genus Paranthropus, that dead-ended, said Sponheimer.
“One key result is that this hominid had a diet fundamentally different from that of all living apes, and, by extension, favored very different environments,” he said. “And having a good idea of where these ancient creatures lived and what they ate helps us understand why some early hominids left descendants and others did not.”
The first skull of a Paranthropus boisei individual was discovered by co-author Meave Leakey’s in-laws, Mary and Louis Leaky, in 1959 in Tanzania.
In 2006, a team led by Sponheimer found that a cousin of Paranthropus boisei known as Paranthropus robustus had a far more diverse diet than once believed, clouding the notion that it was driven to extinction by its picky eating habits. Published in Science magazine, the study showed that Paranthropus robustus had a diverse diet ranging from fruits and nuts to sedges, grasses, seeds and perhaps even animals.
So what led to the end of the line for Paranthropus? It could well have been direct competition with Homo — which was becoming skilled in extensive bone and stone technology — or it could have been a variety of other issues, including a slower reproductive rate for Paranthropus than for Homo, he said.
The new study was funded by the National Science Foundation and the CU-Boulder Dean’s Fund for Excellence.
