New species of extinct marsupial lion discovered in Australia
A team of Australian scientists has discovered a new species of marsupial lion which has been extinct for at least 19 million years. The findings are based on fossilized remains of the animal's skull, teeth, and humerus (upper arm bone) found in the Riversleigh World Heritage Area of remote northwestern Queensland.

Tigers cling to survival in Sumatra's increasingly fragmented forests
A research expedition tracked endangered tigers through the Sumatran jungles for a year and found tigers are clinging to survival in low density populations. The study found that well-protected forests are disappearing and are increasingly fragmented: Of the habitat tigers rely on in Sumatra, 17 percent was deforested between 2000 to 2012 alone. Their findings have renewed fears about the possible extinction of the elusive predators.

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.

Tiger bones? Lion bones? An almost extinct cycad? On-the-spot DNA checks at ports of entry
Wildlife species are going extinct faster than humankind can reliably keep track of. Meanwhile, wildlife crime evolves quickly, with new tricks fueling a lucrative illegal global trade. As a result, customs and other port-of-entry officials confronted with unidentifiable bits of animals and plants need to make rapid decisions based on reliable information. LifeScanner LAB-IN-A-BOX, a portable DNA barcoding lab can serve as a new tool for rapid on-site species identification, adding to law enforcement's arsenal.

Scientists investigate how different houses and lifestyles affect which bugs live with us
Humans have lived under the same roof with bugs since we first began building shelters 20,000 years ago. Now, scientists are studying how physical factors of our homes -- from the floor plan and the number of windows to even how tidy we are -- may play a role in the diversity of the multi-legged communities populating the indoor environment.

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.

Mountain lions fear humans, fleeing when they hear our voices, new study reveals
New research into the behavior of mountain lions indicates they don't like encountering humans any more than we like bumping into them on hiking trails. The findings are particularly valuable as human development encroaches on lion habitat and drives up the number of human-puma encounters.

Ancient DNA reveals role of Near East and Egypt in cat domestication
DNA found at archaeological sites reveals that the origins of our domestic cat are in the Near East and ancient Egypt. Cats were domesticated by the first farmers some 10,000 years ago. They later spread across Europe and other parts of the world via trade hub Egypt. The DNA analysis also revealed that most of these ancient cats had stripes: spotted cats were uncommon until the Middle Ages.

Wolves need space to roam to control expanding coyote populations
Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded, according to a new study. The results were similar across three continents, showing that as top predators' ranges were cut back and fragmented, they were no longer able to control smaller predators.

Look to lactate to help predict ill cats' prognoses
Researchers performed a retrospective study of cats treated in the intensive care unit of Penn's Ryan Hospital. In cats with low blood pressure, the researchers found that animals with a normal level of lactate, a byproduct of metabolism under low-oxygen conditions, were more likely to survive to discharge than those with high lactate levels.

Skull of saber-toothed cat found almost complete
An excavation team found the remains of a saber-toothed cat at the archeological site in Schöningen. An examination of the skull fragments revealed the animal to be a representative of the European saber-toothed cat, Homotherium latidens. The recent discovery constitutes the third example of this large predatory cat from Schöningen.

How cheetahs stay fit and healthy
Cheetahs are categorized as vulnerable species, partly because they have been considered to be prone to diseases due to their supposed weak immune system. However, they are hardly ever sick in the wild. A research team has recently discovered that cheetahs have developed a very efficient innate “first line of defense” immunity to compensate potential deficiencies in other components of their immune system.

Clown tree frogs: Newly discovered and already threatened?
An international team of scientists discovered two new species of clown tree frogs in the Amazon region. Until recently, these colorful amphibians had erroneously been considered part of another species. Now, DNA studies and an analysis of the calls of the examined populations revealed a much higher diversity within this group of frogs. Due to their small distribution areas, it is likely that the newly discovered species are threatened, but the determination of their protection status is currently still pending.
