How will rising sea levels impact the Phillippines?

More than 167,000 hectares of coastland -- about 0.6% of the country's total area -- are projected to go underwater in the Philippines, especially in low-lying island communities, according to research by the University of the Philippines.

Low-lying countries with an abundance of coastlines are at significant risk from rising sea levels resulting from global warming. According to data by the World Meteorological Organisation, the water levels around the Philippines are rising at a rate almost three times the global average due partly to the influence of the trade winds pushing ocean currents.

On average, sea levels around the world rise 3.1 centimetres every ten years. Water levels in the Philippines are projected to rise between 7.6 and 10.2 centimetres each decade.

The fish that cools off by jumping OUT of the water

On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph.

In the study published today in the journal Biology Letters, the researchers describe how these fish air-chill themselves on solid ground in order to drop their body temperatures. The researchers also found that fish exposed to higher temperatures for a week tolerated warmer water better.

The fish jump out of the water to escape rising temperatures, said integrative biology professor Pat Wright, senior author of the study.

Dirty pipeline: Methane from fracking sites can flow to abandoned wells, new study shows

As debate roils over EPA regulations proposed this month limiting the release of the potent greenhouse gas methane during fracking operations, a new University of Vermont study funded by the National Science Foundation shows that abandoned oil and gas wells near fracking sites can be conduits for methane escape not currently being measured.

The study, to be published in Water Resources Research on October 20, demonstrates that fractures in surrounding rock produced by the hydraulic fracturing process are able to connect to preexisting, abandoned oil and gas wells, common in fracking areas, which can provide a pathway to the surface for methane.

A recent paper published in the Proceedings of the National Academies of Science showed that methane release measured at abandoned wells near fracking sites can be significant but did not investigate how the process occurs.

NASA studies LA earthquake

A new NASA-led analysis of a moderate magnitude 5.1 earthquake that shook Greater Los Angeles in 2014 finds that the earthquake deformed Earth's crust across a broad region encompassing the northern Los Angeles Basin and northern Orange County. The shallow ground movements observed from this earthquake likely reflect strain accumulated on deeper faults, which remain locked and may be capable of producing future earthquakes.

A team of NASA and university researchers led by geophysicist Andrea Donnellan of NASA's Jet Propulsion Laboratory, Pasadena, California, used GPS and NASA airborne radar data to measure surface deformation in Earth's crust caused by the March 28, 2014, earthquake, which was centered in La Habra, California. The earthquake was felt widely in Orange, Los Angeles, Ventura, Riverside, San Bernardino, Kern and San Diego counties. While the earthquake was relatively moderate in size, the earthquake's depth (3.6 miles, or 5.85 kilometers) and location within a highly populated region resulted in more than $12 million in damage. Most of the damage occurred within a 3.7-mile (6-kilometer) radius of the epicenter, with a substantial amount of damage south of the main rupture.

Heavy rain doesn't mean more trees in African savanna

In 2011, satellite images of the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had expected. Scientists supposed that the ecosystem's high annual precipitation would result in greater tree growth. Yet a 2011 study found that the more instances of heavy rainfall a savanna received, the fewer trees it had.

To this ecological riddle, Princeton University researchers might have finally provided a solution.

Mice stutter too

About 70 million people worldwide stutter when they speak, and it turns out humans aren’t the only ones susceptible to verbal hiccups. Scientists at this year’s Society for Neuroscience Conference in Chicago, Illinois, show that mice, too, can stumble in their vocalizations. In humans, stuttering has long been linked to a mutation in the “housekeeping” gene Gnptab, which maintains basic levels of cellular function. To cement this curious genetic link, researchers decided to induce the Gnptab “stutter mutation” in mice. They suspected the change would trigger a mouse version of stammering. But deciphering stuttered squeaks is no easy task, so researchers set up a computerized model to register stutters through a statistical analysis of vocalizations.

Bees don't like diesels!

Diesel fumes may be reducing the availability of almost half the most common flower odours that bees use to find their food, new research has found.

The new findings suggest that toxic nitrous oxide (NOx) in diesel exhausts could be having an even greater effect on bees’ ability to smell out flowers than was previously thought.

NOx is a poisonous pollutant produced by diesel engines which is harmful to humans, and has also previously been shown to confuse bees’ sense of smell, which they rely on to sniff out their food.

"Good" cholesterol may not be so good after all for older women

Researchers in the United States have found that hormonal changes in women during the menopause can cause so-called ‘good cholesterol’ to become dangerous to their health. EurActiv France reports

'Good cholesterol' usually protects the arteries by helping to transport 'bad cholesterol' to the liver to be processed. But recent research in the United States suggests that the risk of heart disease in women increases dramatically after the menopause, because even good cholesterol becomes harmful.

According to the ten-year study carried out on 1,054 American women by Karen Matthews, of the University of Pittsburgh, women's cholesterol levels tend spike after the menopause, placing them at greater risk of cardiovascular events.

Volkswagen begins recalling diesels in Europe

The good news for Volkswagen is that it delivered almost 7.5 million vehicles to customers during the first three quarters of 2015. The bad news is that 8.5 million of VW’s cars will most likely be subject to a mandatory recall — and that’s just in Europe.

The fallout from the Volkswagen emissions scandal continues to reverberate, four weeks after revelations about the installation of “defeat device” software in diesel-powered cars slammed the newswires. Now, the world’s largest automaker is facing a global public relations crisis. This includes its home base: 2.8 million of the recalled vehicles were sold in Germany.

Global Ocean found in Saturn's Moon Enceladus

A global ocean lies beneath the icy crust of Saturn's geologically active moon Enceladus, according to new research using data from NASA's Cassini mission. 

Researchers found the magnitude of the moon's very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, meaning a global ocean must be present. 

The finding implies the fine spray of water vapor, icy particles and simple organic molecules Cassini has observed coming from fractures near the moon's south pole is being fed by this vast liquid water reservoir. The research is presented in a paper published online this week in the journal Icarus.
