SOLOMON ISLANDS (April 16, 2018) - Globally, remaining tropical forests are being rapidly cleared, particularly in countries like the Solomon Islands where commercial logging accounts for about 18 percent of government revenue, and at least 60 percent of exports while providing the largest number of formal sector jobs. However, the loss of native forests has huge ecological and social consequences, many of which are poorly documented.

Trade and social networking helped our Homo sapiens ancestors survive a climate-changing volcanic eruption 40,000 years ago, giving hope that we will be able to ride out global warming by staying interconnected, a new study suggests.

Analyzing ancient tools, ornaments and human remains from a prehistoric rock shelter called Riparo Bombrini, in Liguria on the Italian Riviera, archeologists at Université de Montréal and the University of Genoa conclude that the key to survival is cooperation.

A team from the Spanish National Cancer Research Centre (CNIO) has determined for the first time the high-resolution structure of a complex (R2TP) involved in key processes for cell survival and in diseases such as cancer. This achievement has been made possible by using high-resolution cryo-electron microscopy, a technique brought to the CNIO thanks to Óscar Llorca, director of the Structural Biology Programme and lead author on the paper published in Nature Communications.

RIVERSIDE, Calif. -- A team of researchers at the University of California, Riverside have isolated three previously unknown bacterial species from wild bees and flowers. The bacteria, which belong to the genus Lactobacillus, may play a role in preserving the nectar and pollen that female bees store in their nests as food for their larvae.

CORVALLIS, Ore. - New research shows that extreme climate variability over the last century in western North America may be destabilizing both marine and terrestrial ecosystems.

Climate is increasingly controlling synchronous ecosystem behavior in which species populations rise and fall together, according to the National Science Foundation-funded study published in the journal Global Change Biology.

MISSOULA - A University of Montana researcher and her collaborators have published a new study that reveals increased risks for Alzheimer's and suicide among children and young adults living in polluted megacities.

Chara algae are ancient plant organisms that are commonly found in freshwater reservoirs and occur, though more rarely, in water bodies with salt water. An unusual feature of this type of algae is the huge size of individual cells, which can reach up to 1 mm in diameter and up to several centimeters in length. This feature makes Characean algae a unique object for the study of intracellular signals, which are associated with the appearance of signaling molecules in some parts of the cell (for example, when they are touched or illuminated) and their propagation to other cell areas.

April 13, 2018--Even the briefest increase in airborne fine particulate matter PM2.5, pollution-causing particles that are about 3 percent of the diameter of human hair, is associated with the development of acute lower respiratory infection (ALRI) in young children, according to newly published research. Increases in PM2.5 levels also led to increased doctor visits for these lung infections.

People in crowded urban areas - especially poor areas - see fewer songbirds such as tits and finches, and more potential "nuisance" birds, such as pigeons, magpies and gulls, new research shows.

The University of Exeter and the British Trust for Ornithology examined ratios of birds-to-people and found areas of high-density housing have fewer birds overall - and the birds people do see are just as likely to cause a nuisance as to make them happy.

A new study by geoscientists at the University of Liverpool has identified the temperature at which cooling magma cracks to form geometric columns such as those found at the Giant's Causeway in Northern Ireland and Devils Postpile in the USA.

Geometric columns occur in many types of volcanic rocks and form as the rock cools and contracts, resulting in a regular array of polygonal prisms or columns.

Columnar joints are amongst the most amazing geological features on Earth and in many areas, including the Giant's Causeway, they have inspired mythologies and legends.
