"Shallow" sports and "deep" social hierarchies: Not all pecking orders are created equally
University of Michigan researchers have added a new dimension to the mathematics used to predict the outcomes of all manner of competitions, including sports, games and social hierarchies in both humans and animals......»»
New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
Defibrillation devices can still save lives using 1,000 times less electricity, optimized model finds
In a paper published in Chaos, researchers from Sergio Arboleda University in Bogotá, Colombia, and the Georgia Institute of Technology in Atlanta used an electrophysiological computer model of the heart's electrical circuits to examine the effect o.....»»
Study reveals effect of slope position on nonstructural carbohydrates in biological soil crusts
Nonstructural carbohydrates (NSCs) provide energy for metabolic processes in plants and play a key role in plant growth, defense and osmoregulation. However, the regulation of NSC in biological soil crusts across different slope positions remains unc.....»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
Researchers are developing the next generation of sensors to improve horse welfare
While talking to horses and other animals seems like a far-fetched fantasy, University of Missouri engineers are developing technology that puts us one step closer to that reality......»»
Cobalt-copper tandem system offers sustainable approach for converting carbon dioxide to ethanol
The continuing release of carbon dioxide into the atmosphere is a major driver of global warming and climate change with increased extreme weather events. Researchers at Johannes Gutenberg University Mainz (JGU) have now presented a method for effect.....»»
Only 3% of South Africans can name all five national animals and plants. Why these symbols matter
Alongside a national flag, anthem and coat of arms, most countries have one or more plant and animal species that they designate as national symbols. The national animal of China, for example, is the giant panda, a nation-wide source of pride and dip.....»»
UN summit approves fund to share benefits of nature"s sequenced genetic data
A UN nature summit agreed in Colombia Saturday on the creation of a fund to share the profits of digitally sequenced genetic data taken from animals and plants with the communities they come from......»»
Not too big, not too small: Why modern humans are the ideal size for speed
The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title.....»»
African Sahara "greening" can alter Northern Hemisphere climate, modeling study finds
Africa's Sahara Desert may be considered a vast expanse of barren sand with limited vegetation, an extreme environment for plants and animals to thrive, but life always finds a way. Indeed, vegetation growth in the desert has waxed and waned over mil.....»»

Researchers study effect of phosphorous and irradiance on the invasive plant Chromolaena odorata
Resource competition is an important factor affecting the invasion success of alien plants, and environmental factors influence the competition outcomes between invasive and native plants. Chromolaena odorata has been listed as one of the main invasi.....»»
A comparison of bat and bird wings reveals their evolutionary paths are vastly different
Bats are incredibly diverse animals: They can climb onto other animals to drink their blood, pluck insects from leaves or hover to drink nectar from tropical flowers, all of which require distinctive wing designs......»»
Using mathematics to better understand cause and effect
Cause and effect. We understand this concept from an early age. Tug on a pull toy's string, and the toy follows. Naturally, things get much more complicated as a system grows, as the number of variables increases, and as noise enters the picture. Eve.....»»

No, but the direction of our hair whorls could teach us about human development.....»»
Nigeria"s last elephants: What must be done to save them?
Nigeria has a unique elephant population, made up of both forest-dwelling (Loxodonta cyclotis) and savanna-dwelling (Loxodonta africana) elephant species. But the animals are facing unprecedented threats to their survival. In about 30 years, Nigeria'.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
How researchers can maximize biological insights using animal-tracking devices
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell a deeper story about the lives of.....»»
Algae-jellyfish relationship provides insight on immune health
Marine animals like jellyfish, corals and sea anemones often live with algae inside their cells in a symbiotic relationship. The animals give the algae nutrients and a place to live; in return, algae give the animals some of the food they make from s.....»»
