NASA's Aqua satellite watches Tropical Storm Ana intensifying
2014-10-15
(Press-News.org) NASA's Aqua satellite passed over intensifying Tropical Storm Ana as it was moving through the Central Pacific Ocean and toward the Hawaiian Islands.
On Oct. 14 at 22:50 UTC (6:50 p.m. EDT) the MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Storm Ana in the Central Pacific Ocean. The MODIS image showed a tight concentration of thunderstorms surrounding the center of Ana's circulation.
At 1500 UTC (11 a.m. EDT/5 a.m. HST) on Wed. Oct. 15, Tropical Storm Ana's maximum sustained winds were near 70 mph (110 kph). Ana is forecast to gradually intensify through Thursday night, and it may become a hurricane later today or tonight, according to the Central Pacific Hurricane Center.
The center of tropical storm Ana was located near latitude 14.3 north, longitude 146.5 west. That's about 680 miles (1095 km) southeast of Hilo, Hawaii. Ana is moving toward the west near 9 mph (15 kph), and this general motion is expected to continue today, with a gradual turn toward the west northwest expected tonight or early Thursday, and this motion is expected to continue through late Thursday.
Ana is expected to begin causing life-threatening surf and riptide conditions through the Hawaiian Islands beginning Thursday, Oct. 16. CPHC noted that surf produced by these swells may be potentially damaging along some shorelines starting on Friday. There are no coastal watches or warnings in effect, however, a hurricane watch may be required for portions of the main Hawaiian Islands later today or tonight (Oct. 15).
Ana is moving northwest and intensifying. The CPHC expects Ana to become a hurricane late on Oct. 15. By the weekend of Oct. 18-19, Ana is forecast to approach the main Hawaiian Islands.

Nanomedicines consisting of nanoparticles for targeted drug delivery to specific tissues and cells offer new solutions for cancer diagnosis and therapy. Understanding the interdependency of physiochemical properties of nanomedicines, in correlation to their biological responses and functions, is crucial for their further development of as cancer-fighters.
"To develop next generation nanomedicines with superior anti-cancer attributes, we must understand the correlation between their physicochemical properties—specifically, particle size—and their interactions ...

Researchers in Syracuse University's College of Arts and Sciences are pairing chemical analyses with micropaleontology—the study of tiny fossilized organisms—to better understand how global marine life was affected by a rapid warming event more than 55 million years ago.
Their findings are the subject of an article in the journal Paleoceanography (John Wiley & Sons, 2014).
"Global warming impacts marine life in complex ways, of which the loss of dissolved oxygen [a condition known as hypoxia] is a growing concern" says Zunli Lu, assistant professor of ...

A new study using a reconstruction of North American drought history over the last 1,000 years found that the drought of 1934 was the driest and most widespread of the last millennium.
Using a tree-ring-based drought record from the years 1000 to 2005 and modern records, scientists from NASA and Lamont-Doherty Earth Observatory found the 1934 drought was 30 percent more severe than the runner-up drought (in 1580) and extended across 71.6 percent of western North America. For comparison, the average extent of the 2012 drought was 59.7 percent.
"It was the worst by a ...

This week, researchers from University of Hawai'i, Norway, and the UK have shown with innovative experiments that a rise in jellyfish blooms near the ocean's surface may lead to jellyfish falls that are rapidly consumed by voracious deep-sea scavengers. Previous anecdotal studies suggested that deep-sea animals might avoid dead jellyfish, causing dead jellyfish from blooms to accumulate and undergo slow degradation by microbes, depleting oxygen at the seafloor and depriving fish and invertebrate scavengers, including commercially exploited species, of food.

PROVIDENCE, R.I. [Brown University] — Imagine that a time machine has transported you to the Australian outback 100,000 years ago. As you emerge, you see a huge kangaroo with a round rabbit-like face foraging in a tall bush nearby. The animal's surprising size makes you gasp aloud but when it hears you, becoming equally unnerved, it doesn't hop or lumber away on all fours and tail like every kangaroo you've seen in the present. It walks on its feet. One at a time. Like you.
In a new paper in the journal PLoS ONE, a team of researchers led by Christine Janis, professor ...

Now extinct giant kangaroos most likely could not hop and used a more rigid body posture to move their hindlimbs one at a time, according to a study published October 15, 2014 in the open-access journal PLOS ONE by Christine Janis from Brown University and colleagues.
The "short-faced," large-bodied sthenurine kangaroos–a now extinct relative to modern-day kangaroos–first appeared in the middle Miocene and became extinct in the late Pleistocene. The largest of these kangaroos had an estimated body mass of 240 kg, almost three times the size of the largest ...

Thousands of birds are attracted to lights–sometimes referred to as light-pollution–every year worldwide during their first flights from their nests to the open ocean, a phenomenon called 'fallout.' Short-tailed shearwater breeding on the coast of ...

Research from the University of Exeter has revealed that the rock goby (Gobius paganellus), an unassuming little fish commonly found in rock pools around Britain, southern Europe, and North Africa, is a master of camouflage and can rapidly change colour to conceal itself against its background.
Whether hiding from predators or from families hunting in rock pools, the rock goby can change both its colour and brightness to match its background in just one minute.
Dr Martin Stevens from the Centre for Ecology and Conservation at the University of Exeter's Penryn Campus ...
