Evidence of Sea-level Change in Southeast Asia 6,000 Years Ago Has Implications for Today's Coastal Dwellers, Rutgers Study Finds

For the 100 million people who live within 3 feet of sea level in East and Southeast Asia, the news that sea level in their region fluctuated wildly more than 6,000 years ago is important, according to research published by a team of ocean scientists and statisticians, including Rutgers professors Benjamin Horton and Robert Kopp and Rutgers Ph.D. student Erica Ashe. That’s because those fluctuations occurred without the assistance of human-influenced climate change.

In a paper published in Nature Communications, Horton, Kopp, Ashe, lead author Aron Meltzner and others report that the relative sea level around Belitung Island in Indonesia rose twice just under 2 feet in the period from 6,850 years ago to 6,500 years ago. That this oscillation took place without any human-assisted climate change suggests to Kopp, Horton and their co-authors that such a change in sea level could happen again now, on top of the rise in sea level that is already projected to result from climate change. This could be catastrophic for people living so close to the sea.

NASA's Spots Tropical Cyclone Carlos' Night-time Stretch

NASA-NOAA's Suomi NPP satellite captured a night-time image of Tropical Cyclone Carlos using infrared light that showed the storm was being stretched out. Carlos is being adversely affected by the Westerlies.

Pre-eclampsia deaths are avoidable

Pregnancy in the UK has never been safer, say scientists from King's College London writing in the latest edition of The Lancet.

Litter Levels in the Depths of the Arctic are On the Rise

The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in a study by researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).

Research suggests wearing police uniform changes the way brain processes information

New research from a team of cognitive neuroscientists at McMaster suggests that simply putting on a uniform, similar to one the police might wear, automatically affects how we perceive others, creating a bias towards those considered to be of a low social status.

Scientists estimate solar nebula's lifetime

About 4.6 billion years ago, an enormous cloud of hydrogen gas and dust collapsed under its own weight, eventually flattening into a disk called the solar nebula. Most of this interstellar material contracted at the disk’s center to form the sun, and part of the solar nebula’s remaining gas and dust condensed to form the planets and the rest of our solar system.

UCI, NASA reveal new details of Greenland ice loss

Less than a year after the first research flight kicked off NASA’s Oceans Melting Greenland campaign, data from the new program are providing a dramatic increase in knowledge of how Greenland’s ice sheet is melting from below. Two new research papers in the journal Oceanography, including one by UCI Earth system scientist Mathieu Morlighem, use OMG observations to document how meltwater and ocean currents are interacting along Greenland’s west coast and to improve seafloor maps used to predict future melting and sea level rise.

Newly engineered material can cool roofs, structures with zero energy consumption

A team of University of Colorado Boulder engineers has developed a scalable manufactured metamaterial — an engineered material with extraordinary properties not found in nature — to act as a kind of air conditioning system for structures. It has the ability to cool objects even under direct sunlight with zero energy and water consumption.

Real-time feedback helps save energy and water

Those who take long showers use a great deal of water and energy. Yet people who enjoy taking long showers do not usually realize to what extent they are damaging the environment. However, if a clever measuring system shows current consumption, this immediately leads to increased efficiency. The consumption information available on the display is incentive enough to reduce water and energy consumption when showering on average by 22 per cent. This was shown by a study conducted by the Universities of Bonn and Bamberg, as well as ETH Zurich. The results have initially been published online in the journal Management Science. The print edition will be published soon.

Organic matter composition found to be critical factor in mercury methylation

The biological formation of neurotoxic methyl mercury is an enigmatic process underpinning mercury-related health and environmental hazards. Nevertheless, the exact mechanisms and the factors controlling the process are still not well understood.

In a collaborative effort, researchers at Uppsala and Umeå University now show that the formation of methylmercury in sediment is controlled by the molecular composition of the organic matter. The study has been published in Nature Communications.
