Massive Landfill Site Turns Into Thriving Eco-Park

Israel’s largest landfill dump has undergone a massive makeover that has seen the mountain of garbage turn into a 2,000-acre ecological park three times the size of New York City’s Central Park. This new “green lung,” which includes a 150-acre recycling station, walking and cycling trails, ponds and extreme sports activities, will soon be home to a 50,000-seat amphitheater, one of the largest concert venues in Israel. And if that’s not enough, the biogas from this landfill, once a toxic pollutant, is now being reused as green energy.

The multi-million-dollar makeover of Hiriya, which started in 2001, has proven to benefit both the surrounding environment and visitors from all over the world. Now, what once was a huge dump between Road 4 and Road 461 in central Israel known for its unpleasant past, is no longer Israel’s ugliest site. 

The effects of Global warming on fisheries assessed in new study

A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will cause major changes in marine biodiversity.

Since upwelling of colder, nutrient-rich water is a driving force behind marine productivity, one possibility may be enhancement of some of the world’s most important fisheries.

However, solar heating due to greenhouse warming may also increase the persistence of “stratification,” or the horizontal layering of ocean water of different temperatures. The result could be a warm, near-surface layer and a deep, cold layer.

Oil Train Derailment Causes Huge Fire in West Virginia

A huge fire is burning out of control in West Virginia and 1,000 people have been evacuated from their homes, after a train carrying crude oil derailed. When the accident happened, on the afternoon of Monday, February 16, crude oil began pouring into a river that supplies drinking water. Officials noted that at least one of the derailed tanker cars fell into the Kanawha River. The area is about 30 miles from the location where 10,000 gallons of a coal industry chemical called crude MCHM spilled and tainted the drinking water supply a little over one year ago.

Feds Propose Protection of Calving, Foraging Areas of Last 450 Right Whales on East Coast

In response to the efforts of conservation and wildlife protection groups, the National Marine Fisheries Service today proposed to protect 39,655 square miles as critical habitat for North Atlantic right whales. Only about 450 of the critically endangered whales exist today, and without additional protections the species faces a serious risk of extinction.

Harsh winter in Eastern US result of warming Arctic and shifting jet stream

Prolonged cold snaps on the East Coast, California drought and frozen mornings in the South all have something in common – the atmospheric jet stream which transports weather systems that’s  taken to meandering all over North America.

Rutgers University climate scientist Jennifer Francis and colleagues link that wavy jet stream to a warming Arctic, where climate changes near the top of the world are happening faster than in Earth’s middle latitudes.

A new study from Francis and University of Wisconsin-Madison scientist Stephen Vavrus, published in IOPscience, backs up that theory, with evidence linking regional and seasonal conditions in the Arctic to deeper north-south jet stream waves which will lead to more extreme weather across the country.

New ozone-destroying gases on the rise

Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion. In the new study, published today in Nature Geoscience, the scientists also report the atmospheric abundance of one of these ‘very short-lived substances’ (VSLS) is growing rapidly.

'Hidden Order' Physics Mystery getting less mysterious thanks to Rutgers scientists

A new explanation for a type of order, or symmetry, in an exotic material made with uranium may lead to enhanced computer displays and data storage systems, and more powerful superconducting magnets for medical imaging and levitating high-speed trains, according to a Rutgers-led team of research physicists.

The team’s findings are a major step toward explaining a puzzle that physicists worldwide have been struggling with for 30 years, when scientists first noticed a change in the material’s electrical and magnetic properties but were unable to describe it fully. This subtle change occurs when the material is cooled to 17.5 degrees above absolute zero or lower (a bone-chilling minus 428 degrees Fahrenheit).

Component in olive oil kills cancer cells

A Rutgers nutritional scientist and two cancer biologists at New York City’s Hunter College have found that an ingredient in extra-virgin olive oil kills a variety of human cancer cells without harming healthy cells.

The ingredient is oleocanthal, a compound that ruptures a part of the cancerous cell, releasing enzymes that cause cell death.

Paul Breslin, professor of nutritional sciences in the School of Environmental and Biological Sciences, and David Foster and Onica LeGendre of Hunter College, report that oleocanthal kills cancerous cells in the laboratory by rupturing vesicles that store the cell’s waste.

A Valentine's Day gift to us all from NASA

Valentine's Day is special for NASA's Voyager mission. It was on Feb. 14, 1990, that the Voyager 1 spacecraft looked back at our solar system and snapped the first-ever pictures of the planets from its perch at that time beyond Neptune. 

This "family portrait" captures Neptune, Uranus, Saturn, Jupiter, Earth and Venus from Voyager 1's unique vantage point. A few key members did not make it in: Mars had little sunlight, Mercury was too close to the sun, and dwarf planet Pluto turned out too dim. 

Beavers provide insight on how to improve our enamel

Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron. This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.
