Quantum effects observed in photosynthesis
Molecules that are involved in photosynthesis exhibit the same quantum effects as non-living matter, concludes an international team of scientists. This is the first time that quantum mechanical behavior was proven to exist in biological systems that are involved in photosynthesis. The interpretation of these quantum effects in photosynthesis may help in the development of nature-inspired light-harvesting devices.

How cheetahs outsmart lions and hyenas
Cheetahs in the Serengeti National Park adopt different strategies while eating to deal with threats from top predators such as lions or hyenas. A new study shows that male cheetahs and single females eat their prey as quickly as possible. Mothers with cubs, on the other hand, watch out for possible threats while their young are eating in order to give them enough time to eat their fill.

Intestinal worms may solve allergy puzzle
While young people with parasite worms currently have a four times higher risk for developing allergies and asthma than others, their parents are generally unaffected. Researchers were surprised when they found that intestinal worms, so-called Helminths (Toxocara Canis) from animals, actually have an influence on allergy- and asthma risk in humans.

Ancient DNA offers new view on saber-toothed cats' past
Researchers who've analyzed the complete mitochondrial genomes from ancient samples representing two species of saber-toothed cats have a new take on the animals' history over the last 50,000 years. The data suggest that the saber-toothed cats shared a common ancestor with all living cat-like species about 20 million years ago. The two saber-toothed cat species under study diverged from each other about 18 million years ago.

Advance achieved in dry preservation of mammalian sperm cells
In an important advance in the preservation of animal reproductive material, researchers have achieved the first successful drying and rehydration of domestic cat sperm using a rapid microwave dehydration method. More challenging to dehydrate than rodent sperm because of the presence of a centrosome, the rehydrated cat sperm were viable and capable of producing blastocysts. Dehydration preservation allows relatively easy, low-tech storage, which could be important in resource-challenged conditions.

How tails help geckos and other vertebrates make great strides
A wagging tail is often associated with dogs' emotions, but the side-to-side motion may also help them take longer strides and move faster, according to a study. The research was done on leopard geckos, which are ideal animals for the study of tail function because they naturally lose their tails as a defense mechanism against predators in a process called autotomy.

Largest-ever study of pets and kids' health finds no link
A large body of research has reported an association between the pet ownership and better health among children. But a new study that is the largest-ever to explore the issue contradicts the common thinking. Researchers did find that children from pet-owning families tended to have better general health, but those differences disappeared when factors such as family income and family housing were considered.

The truth about cats' and dogs' environmental impact
US cats and dogs cause 25-30 percent of the environmental impact of meat consumption in this country. The nation's 163 million cats and dogs eat as much food as all the people in France. People should keep their pets -- and keep feeding them meat -- but there may be steps pet owners can take to reduce their environmental impact, says a researcher.
