No. 1 UConn’s Top Challenge Seems to Be Not Running Out of Players
Missing several key players, the Huskies beat their most formidable league opponent, Louisville, by 17 points.
"ORLANDO,
Fla. — Lasan Kromah and Shabazz Napier each had 17 points and seven
rebounds, and No. 22 Connecticut easily defeated skidding Central
Florida 75-55 on Sunday night.
DeAndre
Daniels had 16 points and seven rebounds for the Huskies (18-5, 6-4
American Athletic Conference), and Ryan Boatright scored 11. UConn led
by 17 at halftime and withstood a mild second-half rally by the Knights
to win for the fourth time in five games."

For Cows, Daughters Mean More Milk
Cows who birthed back-to-back daughters had a bonanza of milk, nearly 1,000 pounds more than those that had given birth to sons, a new study reports.
"The amount of milk a cow produces is affected by the sex of her fetus, a new study reports.
Cows
that gave birth to a daughter produced considerably more milk than
those that had sons. And back-to-back daughters led to a bonanza of milk
from their mothers — over two 305-day lactation periods, nearly 1,000
pounds more milk than from cows that had given birth to sons, an
increase of 3 percent.
The study, described in the journal PLoS ONE, could have implications for dairy farmers and for new discoveries about human breast milk.
“Nobody knew if the fetus could possibly be affecting the mammary glands,” said the first author, Katie Hinde,
an evolutionary biologist at Harvard. But she added, “It might just be
that the developmental needs for sons and daughters are different.”
The
study examined 2.4 million lactations by nearly 1.5 million Holstein
dairy cows in the United States. The data was drawn from numbers
recorded from 1995 to 1999. Though there were striking differences in
quantity between the mothers of sons and of daughters, the milk did not
differ in terms of fat or protein content.
Whether
human mothers produce different milk for sons and daughters deserves
more research, Dr. Hinde said, adding that closer study could lead to
more customized infant milk formulas and to better matches in neonatal
units for babies who need donor breast milk."
