The Ayeyawady River delta in Myanmar is home to millions of people, and is a hub of agricultural activity. Unlike other large rivers across the world, however, the Ayeyawady has been relatively untouched by large infrastructure and dam projects for the past 50 years, and its geologic evolution has never previously been studied.
Standing guard between a cell's nucleus and its main chamber, called the cytoplasm, are thousands of behemoth protein structures called nuclear pore complexes, or NPCs. NPCs are like the bouncers of a cell's nucleus, tightly guarding exactly what goes in and out. Each structure contains about 1,000 protein molecules, making NPCs some of the biggest protein complexes in our bodies. One of the most notable clients of NPCs is a class of molecules known as messenger RNAs, or mRNAs.
Killer whales have a formidable reputation as one of the ocean's most ferocious predators. Hunting stealthily in packs, some populations pursue ocean-going mammals, however, other killer whales prefer to dine on a diet of fish alone, posing little or no threat to the mammals that share their waters.
New research led by scientists from the University of Bristol and Queen Mary University of London has revealed that bumblebees can tell flowers apart by patterns of scent.
Flowers have lots of different patterns on their surfaces that help to guide bees and other pollinators towards the flower's nectar, speeding up pollination.
These patterns include visual signals like lines pointing to the centre of the flower, or colour differences.
A fungal pathogen which has led to the extinction of entire species in South America has been recorded for the first time in critically endangered amphibians in India.
Batrachochytrium dendrobatidis (Bd) can cause the lethal disease chytridiomycosis, and is considered a significant threat wherever it is found.
It was first discovered in the Western Ghats Biodiversity Hotspot, designated one of the eight most important global hotspots and one of the three most threatened by population growth, in 2011.
DURHAM, N.C. -- Efforts to address social inequalities in income, education and employment opportunity can be boosted simply by the manner in which that inequity is presented, according to new research from Duke University's Fuqua School of Business.
If you benefit from an inequity, how you handle the situation could depend upon how it is described to you, Professor Ashleigh Shelby Rosette found.
Her study tested people's willingness to surrender part of a bonus at work as a way of studying the presentation of an unjust imbalance or inequity.
Usually when a tropical cyclone weakens it expands and that's how Tropical Storm Maliksi has appeared in recent NASA satellite imagery as its strength wanes.
On June 10, the MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite captured a visible light image of the storm. The eastern quadrant of the storm appeared stretched out a couple of hundred miles as a result of strong vertical wind shear. In the image, Japan was located to the west of the storm's center.
An international research team led by Takuji Waseda, a professor of the University of Tokyo, Japan, has found an increase in high waves and winds in the ice-free waters of the Arctic Ocean, a potentially dangerous navigational tipping point for the "new and unusual" state of the waters.
The study, led by the London School of Hygiene & Tropical Medicine (LSHTM), is the first systematically to examine the extent to which projected changes such as increases in temperature and reduced water availability could affect the production and nutritional quality of common crops such as tomatoes, leafy vegetables and pulses.
Miles beneath the ocean's surface in the dark abyss, vast communities of subseafloor microbes at deep-sea hot springs are converting chemicals into energy that allows deep-sea life to survive--and even thrive--in a world without sunlight. Until now, however, measuring the productivity of subseafloor microbe communities--or how fast they oxidize chemicals and the amount of carbon they produce--has been nearly impossible.
