While humans sleep less than many of our close relatives among the primates, we seem to be doing so much more efficiently and including more rapid-eye movement, or REM--the high-quality sleep period. A new study looks at this and why that might be.
The squid-like cuttlefish has tricks up its non-sleeves for eluding the ocean's fiercest predator, the shark, and others that would snatch it up for prey.
Hypercarnivores, or enormous predators, most likely shaped the ecosystem during the Pleistocene epoch. Essentially, packs of these large animals controlled populations of herbivores so to preserve the ancient landscapes and valuable vegetation.
In an update on the past couple of years in energy extraction, studies, and fracking in North America, we look at what Nature World News has said and studies have covered.
In a collaborative effort by 11 institutions, a new Tree of Life has been created, merging more than 500 existing, small maps of life-form evolution on this planet. It's available online.
More than 500 dog owners have contributed to a study on dog cognition and problem-solving skills that suggests dogs can be conditioned toward psychological dependence.
China successfully used conservation methods to preserve giant panda populations, but researchers have pointed out some ways that a broader series of efforts could help other animals.
Protected areas in Indonesia have reduced mangrove habitat loss. According to a Duke University study, this also prevented significant amounts of carbon dioxide from being released into the atmosphere.
A new study found that coal ash produced from three major U.S. coal-producing basins contains highly radioactive contaminants.
Drought can cause slow death to forests, says a new study by Duke University. However, the effects are not immediate--so, good news, there is hope for revitalizing such trees.
Learnings here on the ways that dogs perform under increased pressure, and the connection to underlying temperament.
Using a new and gentle processing system via robotic submarine, and going to within a meter or two of the ocean floor, scientists have gathered the first high-volume collection of the ocean's building-block organisms.
