Study forecasts hike in online education
A conservative think tank in California is predicting that
U.S. high schools will be delivering half of their courses
online by the year 2019. Authors of a study conducted by the
Hoover Institution at Stanford University said they expect
online education to surge because it saves money and offers
flexibility, The Christian Science Monitor reported Wednesday.
Teachers in traditional schools can't be as flexible as online
educators because they spend their time delivering one-size-
fits-all lectures, says Michael Horn, co-author of the study.
Horn says teachers will be free to work with students who need
extra help if computers take over the job of delivering the
lectures. "It can change our assumption of what teacher-student
ratios make sense," he said in the Monitor article. While the
efficiency of online learning accounts for its growing
popularity, opponents say there has been little research
assessing the quality of programs and not enough official
oversight. "You have to have high standards, tight oversight,
scrutiny over what teachers are doing," Luis Huerta of Columbia
University's Teachers College, told the Monitor.

Compound might stop cancer progression
U.S. medical scientists say they have discovered a compound
that, in laboratory tests, has shown success in preventing
cancer. University of Oklahoma Health Sciences Center
researchers said the compound, which still faces several rounds
of clinical trials, successfully stopped normal cells from
turning into cancer cells and inhibited the ability of tumors
to grow and form blood vessels. If successful tests continue,
researchers eventually hope to create a daily pill that would
be taken as a cancer preventive. "This compound was effective
against the 12 types of cancers that it was tested on," said
Doris Benbrook, the study's principle investigator. "Even more
promising for health care is that it prevents the transformation
of normal cells into cancer cells and is therefore now being
developed by the National Cancer Institute as a cancer
prevention drug." The synthetic compound directly targets
abnormalities in cancer cell components without damaging normal
cells, researchers said. The disruption causes cancer cells to
die and keeps tumors from forming. Benbrook and her team have
patented the discovery and hope to start clinical trials for
the compound within 5 years.

Polar bear listed as threatened species
U.S. Secretary of the Interior Dirk Kempthorne announced
Wednesday he will order the polar bear to be listed as a
threatened species. Kempthorne said he is accepting the
recommendation of U.S. Fish and Wildlife Service Director
Dale Hall to list the polar bear under the Endangered Species
Act. Officials said scientific evidence shows the ongoing
loss of sea ice threatens, and will likely continue to threaten,
polar bear habitat. The loss of habitat, officials said, puts
polar bears at risk of becoming endangered in the foreseeable
future, the standard established for designating a threatened
species. "I am also announcing that this listing decision will
be accompanied by administrative guidance and a rule that
defines the scope of impact my decision will have, in order to
protect the polar bear while limiting the unintended harm to
the society and economy of the United States," Kempthorne said.
He said his decision was based on three findings. "First, sea
ice is vital to polar bear survival. Second, the polar bear's
sea-ice habitat has dramatically melted in recent decades.
Third, computer models suggest sea ice is likely to further
recede in the future."
