A new study has found that dairy intake — specifically milk and yogurt — is associated with higher bone mineral density in the hip, but not the spine.

We’ve all heard examples of animal altruism: Dogs caring for orphaned kittens, chimps sharing food or dolphins nudging injured mates to the surface. Now, a new study suggests some plants are altruistic, too.

Increased levels of greenhouse gases, particularly carbon dioxide, have been associated with the burning of fossil fuels, deforestation, cultivation of grasslands, drainage of the land, and land use changes. Concerns about long-term shifts in climate patterns have led scientists to measure soil organic carbon (SOC) in agricultural landscapes and to develop methods to evaluate how changes in tillage practices affect atmospheric carbon sequestration.

Acanthaster planci is the principle natural enemy of reef-building corals. Outbreaks of this coral-feeding starfish occur periodically, due to reasons that remain unclear. It decimates entire reefs in the space of just a few years, as has been the case in French Polynesia since 2004.

The mangrove forests in the Guyanas (French Guiana, Surinam and Guyana), which spread across the Orinoco and Amazon deltas, are among the most extensive in the world. This particular ecosystem, between earth and the sea, plays a major role in protecting the particularly unstable muddy coastline against erosion. However, most of the Guyana mangroves have been destroyed to develop the coastal plain. The retreating mangrove wall will result in large-scale coastal erosion, threatening populations and their economic activities, as demonstrated in a new study.

In a project that began with the retinal cells of nocturnal animals and has led to fundamental insights into the organization of genomic DNA, researchers show how the nuclear envelope affects nuclear architecture – and gene regulation.

Researchers have shared a how-to secret for biologists: New code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images.

A worldwide review of global rainfall data has found that the intensity of the most extreme rainfall events is increasing across the globe as temperatures rise.

Broadening of forest-centric focus to river catchment-based conservation framework is required: A new study found that freshwater ecosystems in the Amazon are highly vulnerable to environmental degradation. River, lake and wetland ecosystems —- encompassing approximately one-fifth of the Amazon basin area — are being increasingly degraded by deforestation, pollution, construction of dams and waterways, and over-harvesting of plant and animal species.

When a population is a mixture of exploiters and exploited, the natural outcome is perpetual war. A new model reveals that even with never-ending battles, these two groups can survive, but only if they have room to expand and grow.

A new breakthrough marks the first time anyone has been able to show the actual temperature distribution inside living cells.

Afforestation, planting trees in an area where there have previously been no trees, can reduce the effect of climate change by cooling temperate regions, a new study finds.

Scientists report that they have developed a method that cuts down the time it takes to make new ‘parts’ for microscopic biological factories from 2 days to only 6 hours. The scientists say their research brings them another step closer to a new kind of industrial revolution, where parts for these biological factories could be mass-produced. These factories have a wealth of applications including better drug delivery treatments for patients, enhancements in the way that minerals are mined from deep underground and advances in the production of biofuels.

The population of Yelkouan Shearwater of the French island of Le Levant is seriously under threat due to the invasion of feral cats, according to a French and Spanish joint study. The archipelago is home to the main colonies of this species. Feral cats are considered one of the most dangerous invading species for animals native to Mediterranean Islands.

Coral reefs are predicted to decline under the pressure of global warming. However, a number of coral species can survive at seawater temperatures even higher than predicted for the tropics during the next century. How they survive, while most species cannot, is being investigated.

Researchers report that collective intelligence is vital to certain animals’ ability to evaluate and respond to their environment. The results should prompt a close examination of how endangered group or herd animals are preserved and managed because wild animals that depend on collective intelligence for migration, breeding and locating essential resources could be imperiled by any activity that diminishes or divides the group, such as overhunting and habitat loss.

A new study suggests that some organisms, such as manatees, polar bears or cheetahs, may be in for a rough time as they try to adapt to climate change.

Corn crop residues are often left on harvested fields to protect soil quality, but they could become an important raw material in cellulosic ethanol production. USDA research indicates that soil quality would not decline if post-harvest corn cob residues were removed from fields.

In New Jersey, along Hurricane Sandy’s path of destruction, engineers are using infrared and ultraviolet imaging technology and acoustic emission testing combined with low-altitude aircraft photography to generate detailed maps for recovery workers to triage their efforts.

The Republic of Congo has declared a new national park that protects a core population of the 125,000 western lowland gorillas discovered by WCS in 2008.
