Coastal residents and oil-rig workers may soon have longer warning when a storm headed in their direction is becoming a hurricane, thanks to a University of Illinois study demonstrating how to use existing satellites to monitor tropical storm dynamics and predict sudden surges in strength. Meteorologists have seen large advances in forecasting technology to track the potential path of tropical storms and hurricanes, but they've had little success in predicting storm intensity. One of the biggest forecast problems facing the tropical meteorology community is determining rapid intensification, when storms suddenly transform into much stronger cyclones or hurricanes.

Many fish populations are on the decline. Still there is some positive news. When the new fishing year kicks off on May 1, groundfish fishermen will have more opportunity to fish in Northeast waters, small-vessel owners will get a boost through permit banks, and stocks will continue on the path to rebuilding. This yearâ€™s higher catch limits will affect 12 groundfish stocks. These stocks include: Georges Bank cod, Gulf of Maine cod, Georges Bank yellowtail flounder, Southern New England/Mid-Atlantic yellowtail flounder, Cape Cod/Gulf of Maine yellowtail flounder, American plaice, witch flounder, Georges Bank winter flounder, Southern New England. NOAA has also reopened to commercial and recreational fishing 1,041 square miles of Gulf waters immediately surrounding the Deepwater Horizon wellhead, just east of Louisiana. This is the twelfth and final reopening in federal waters since July 22, and opens all of the areas in Federal waters formerly closed to fishing due to the Deepwater Horizon oil spill.
Amazing: the slow crawl from water to land, New from BBC Earth!

The writer C.S. Lewis once said that "Humans are amphibians â€“ half spirit and half animal." He may have been speaking symbolically, but he wasn't too far from the truth! The name Amphibians comes in essence from the Greek meaning "two" and "modes of life". Their ability to transform from water-breathing juveniles into an air-breathing adults, meant a better chance at finding food and less of a chance that they would have to fight for it. But learning to breathe wasn't the only thing up against these aquatic pioneers. The greatest challenge was how to get there. In the beginning, one group of amphibians developed multi-jointed leg-like fins which allowed them to crawl along the sea floor. And incredibly, the mudskipper pictured above is part of that same family. And not only were their bodies in an evolutionary deviation, but their minds were too!
Breathing Polluted Air Can Disrupt Immune System

Negative health effects from the chronic inhalation of polluted air are well known to cause cardio-respiratory disease. It can be particularly damaging to seniors, children, and people with asthma. Now according to a study from Ohio State University, breathing polluted air can also cause widespread inflammation by triggering the release of white blood cells from bone marrow into the blood stream. The influx of white blood cells can alter the integrity of the blood vessels. The white blood cells are then absorbed into fat tissues where chemicals are released that cause inflammation.

Will electric cars ever become the common way to drive? What is needed is an infrastructure that allows easy recharging of the vehicle (such as gasoline stations are for the internal combustion engine). There are two key barriers to plug-ins: first, the current battery technology is very expensive, adding thousands of dollars to the cost of a plug-in. Next, many well-established sectors must change to accommodate plug-ins. Consumers must learn the pros and cons of a plug-in lifestyle, and a new way of valuing upfront costs against operational savings. Utilities must learn to manage a large and mobile load. Cities, retailers, and other businesses must incorporate a new infrastructure of charge spots. All these players must build a new system of connectivity in order to line up charging times, billing, and consumer preferences.
Earth Day 2011
April 18, 2011 05:55 AM - Andy Soos, ENN
When is Earth Day? In many ways it should be every day but officially it is the anniversary of the first formal celebration on April 22, 1970. An estimated 20 million Americans wearing bell-bottoms and gas masks, gathered to voice their concerns about the deterioration of the environment. Earth Day is celebrated by no one central authority or government. Many different organizations (public, private and individuals) supply personal initiative to the celebration. The closest to a general or national governmental response was the U.S. Environmental Protection Agency on April 16 and 17 on the National Mall. With more than 40 interactive exhibits, kids and adults can have eco-fun with hands on activities, art, music and storytelling with special guests. Special guests include Marcus McNeill from the San Diego Chargers, Madieu Williams from the Minnesota Vikings, and Olympic track star Michael Walton. Visitors learnt how to protect their own health and the environment in which they live.
Incredible rites of passage: Scarred for life, new from BBC Earth
April 18, 2011 05:47 AM - Adelle Havard, BBC Earth
With a dangerous reputation, crocodiles would not be the first animal you would associate with mental and physical strengthening. Surprisingly, the people of Papau New Guinea have a connection between man and beast that marks a boys journey into adulthood. Many traditional celebrations that accompany events like birth, the start of adolescence, marriage, and death are richly integrated with the use of natural materials; such as feather, skin and bone. But when an occasion as serious and important as the coming of age beckons, the rituals connection between cause and effect must reflect this intensity. Many inhabitants of the South Pacific islands practice some form of physical transformation during male adolescence. The sacred act of scarring which people of the Solomon Islands practice can make rituals such as ceremonial hair cutting, and being cast into the wilderness for a short period seem relatively less challenging. For decades, tribes have used the tradition of scarification to mature their young boys into men. For a number of weeks, the boys psychological as well as physical barriers are pushed with consistent verbal taunts as well as public humiliations. However their discipline is yet to be tested to its breaking point.

The U.S. Environmental Protection Agency (EPA) has released action plans to address the potential health risks of methylene diphenyl diisocyanate (MDI), toluene diisocyanate (TDI), and related compounds. Americans may be exposed to these chemicals when they are used in certain applications such as spray foam insulation, sealing concrete or finishing floors. The plans identify a range of actions the agency is considering under the authority of the Toxic Substances Control Act. Spray polyurethane foam (SPF) is a highly-effective and widely used insulation and air sealant material. However, exposures to its key ingredient, isocyanates such as MDI, and other SPF chemicals in vapors, aerosols, and dust during and after installation can cause adverse health effects.
Wolves Taken Off the US Endangered Species List
April 14, 2011 09:22 AM - David A Gabel, ENN
For the first time ever, the US Congress has removed an animal from the Endangered Species List, a process typically done by a federal, non-political, science-based agency. The action by the US Congress sets a new precedent for altering the Endangered Species List based on political influence, enraging environmental groups. The removal would take effect in two western states that have known issues with wolves: Montana and Idaho. Wolves would now be managed by each stateâ€™s wildlife agency, inevitably leading to commercial hunting.
