EPA Rejects Petition to Ban 2,4-D Weed
Killer

An environmental group’s petition to ban the widely used herbicide
2,4-D has been rejected by the U.S. Environmental Protection Agency.

The agency said the petition from the Natural Resources Defense Council
did not adequately show that 2,4-D was harmful under the conditions in
which it is used, The New York Times reported.

The herbicide, first approved in the late 1940s, is one of the most
widely used weed killers in the world. It is used by farmers and is an
ingredient in many home lawn-care products.

In its petition, the Natural Resources Defense Council cited studies
suggesting that exposure to 2, 4-D could cause problems such as cancer,
genetic mutations and hormone disruption, The Times reported.

While some of the studies did suggest that high doses of the herbicide
could be harmful, they did not establish lack of safety, the EPA said in
its ruling.

FDA Delays Decision on Weight-Loss
Drug

U.S. regulators will take another three months to decide whether to
approve a new obesity drug called Qnexa, drugmaker Vivus Inc. said
Monday.

The Food and Drug Administration was scheduled to make a decision by
April 17 but that has been changed to July 17 to give the FDA time to
assess a new drug safety plan submitted by Vivus, the Associated
Press
reported.

The FDA rejected the drug in 2010 over concerns that it can cause heart
palpitations and birth defects if taken by pregnant women. Vivus
resubmitted the drug for approval and an FDA panel of medical advisers
voted in February to recommend approval of the drug.

However, the FDA does not have to follow the advice of its expert
panels.

If approved, Qnexa would become the first new prescription weight loss
pill to reach the U.S. market in more than a decade, the AP
reported.

First Months of 2012 Warmest on Record in
U.S.

The United States had record warm temperatures during the first few
months of 2012, especially in March.

In the lower 48 states, temperatures were 6 degrees higher than average
for the first three months of year, and 8.6 degrees above normal in March,
according to the National Oceanic and Atmospheric Administration, the
Associated Press reported.

The warm temperatures in the first three months broke the previous
January-March record by 1.4 degrees.

The warm start to 2012 is the result of an unusual combination of La
Nina and a number of other weather patterns, according to
meteorologists.

The 2011-12 winter was the fourth warmest on record in the United
States and the period since last April has been the warmest 12-month
stretch on record, NOAA climate scientist Jake Crouch told the
AP.
