A University of Nevada team, led by anthropologist Peter Gray, tested several hypotheses about pets and contemporary courtship or dating rituals. Their study will appear in a forthcoming issue of the journal Anthrozoös.
This may be the first known case of simplification from a macro to a microorganism, a cheap trick which evolution likely used more than once though.
A paper published recently in Nature Communications details how a team lead by Dr. Ben Wilson and Professor Chris Petkov used a brain imaging technique to identify the neuronal evolutionary origins of language. Their findings help us understand how we learn to speak, and could allow new treatments for those who lose this ability from aphasia after a stroke or dementia.
Showcased are some of the most amazing designs that mimic nature closely: man-made, but defined by their allegiance to nature.
The bat is the only flying mammal and among the heaviest in the world. To top it over, it can land upside down a perplexing acrobatic feat which has left scientists scratching their heads for many years. After carefully and systematically studying bat upside landings in slow motion, a group of researchers thinks it has cracked the puzzle: bats employ a nifty trick where one wing stays flapping while the other is moved close to the body. This asymmetry corrects the moment of inertia and center of mass so the bats always land safely upside down.
A recent study from Iowa State University shows how a gene, found in a single plant species so far, can increase protein content when grafted into the DNA of staple crops. Their findings could help improve a huge variety of crops and improve nutrition in developing parts of the world, where available sources of protein are sometimes limited.
Unfortunately, stories of animals becoming endangered are way more common than the reverse, but perhaps this makes it even more important to celebrate the success we do have.
A team of researchers has analyzed a swarm of data and created the first map that tries to estimate how much water is located beneath the Earth.
The collapse of two dams at a Brazilian mine spells an absolute catastrophe, with effects that could haunt Brazil for years to come.
Some 360 million years ago, the oceans were teeming with big fish, some as big as a school bus. Then something terrible happened, the causes of which still escape scientists today: the Hangenberg Event. This was the last peak in a streak of mass extinctions known as the Late Devonian extinction which exterminated 97% of all marine vertebrate species. In the aftermath, it paid to be small a new study suggests. The researchers at University of Pennsylvania found that small fish dominated the ecological niches for nearly 40 million years. This tremendous rebound time is relevant today when overfishing is threatening countless large fish species. Once these disappear, it might be a very long time before we get tuna-sized fish back on our plates.
