Spill update: From booms to dispersants

Choppy seas prevailed in the northern Gulf of Mexico on May 13, with even protected waters hostingrough 4 to 5 foot waves, according to the Coast Guard. But three-plus weeks into the Deepwater Horizon explosion and ensuing spill from a BP exploratory well, measures to respond to the catastrophe continued ramping up.

Chinese would turn cigarette butts into steel’s guardian

People smoke a lot of cigarettes, which leads to a lot of trash. Tom Novotny has done the math: An estimated 5.6 trillion butts each year end up littering the global environment. But Chinese researchers have a solution: recycling. Their new data indicate that an aqueous extract of stinky butts makes a great corrosion inhibitor for steel.

Atrazine paper’s challenge: Who’s responsible for accuracy?

As a new critique of a review paper on atrazine suggests, some papers may simply overtax a journal’s fact-vetting enterprise. Which would be bad for science. And bad for society.

A Gulf spill news review

Oil companies have said it's possible the gusher could grow substantially before its capped.

Preventing disastrous offshore spills may require space-program diligence

As crude oil continues to spew from the Gulf of Mexico seafloor — two weeks now after the Deepwater Horizon accident and sinking — questions continue to surface about what went wrong. To my mind, what went wrong was almost blind optimism on the part of industry, regulators, the states and the public. And any niggling doubt about the wisdom of that optimism was likely assuaged by at least a little greed.

BP oil rig’s sinking and gushing crude raise questions

Around 10 p.m. local time on April 20, the Deepwater Horizon — a floating oil-drilling platform leased to British Petroleum — suffered an explosion and fire about 40 miles off the Louisiana coast. While the aftermath of that devastating accident is now being observed and chronicled in painful detail, even the most basic features of what triggered it remain sketchy.

Vitamin D: Obese and ‘uniform’ risks

Although Vitamin D insufficiency has reached what might be considered epidemic proportions, it’s failed to move onto the radar screens of most physicians, much less consumers. A host of new studies now link excess weight with a deficiency in this, the sunshine vitamin. But that wouldn’t explain why female soldiers become increasing D-ficient during basic combat training. For them, an Army study suggests, the problem may trace to what they wear.

Chili pepper holds hot prospects for painfree dieting

A cousin of the chemical that packs the heat in chilis not only can rev up the body’s metabolism but actually encourage it to preferentially burn fat, according to a new trial in obese men and women. And the kicker: The molecule is itself so fat that it can’t fit into the receptors that would ordinarily register pain.

This off-white rice may be heart healthy

The outer coating of a semi-polished rice – a layer which manufacturers ordinarily polish off of brown rice in the process of making it white – offers cardiovascular benefits, new data indicate.

Baby’s calcium might play defining role in adult bone health

Calcium makes bones strong. But a new animal study suggests that to do this, ample calcium may need to be available from birth. Too little in the early weeks of life may reprogram certain stem cells – those in the marrow – in ways that permanently compromise bone structure. Perhaps even fostering osteoporosis.

Women of childbearing age still aren’t getting enough folic acid

To head off a risk of neural tube defects, a class of potentially devastating birth defects, women of childbearing age are supposed to get at least 400 micrograms of folic acid daily. A government study now finds that the vast majority of these women fall short. It finds that the national average for women in this age group is some 40 percent below the recommended minimum.

Data from many drug trials for stroke go unpublished

Important details from roughly one in five drug trials for the acute treatment of the most common type of stroke have never entered the public domain, a new study finds. The masked data come from 125 trials that tested effects of 89 different drugs.
