Lemurs: Secret Social Drama Among Humanity’s Distant Cousins:

The guys were all stressed out. There were new infants in the community, and the guys knew from experience that that’s when invaders were likely to come and kill the babies, particularly the male infants.

Birds Move North With Climate Change:

For the first time, researchers have documented a shift in breeding ranges for northerly species in North America. The study parallels findings in Europe.

Tropical Lizards Can’t Take The Heat Of Climate Warming:

From geckos and iguanas to Gila monsters and Komodo dragons, lizards are among the most common reptiles on Earth. They are found on every continent except Antarctica. One even pitches car insurance in TV ads. They seemingly can adapt to a variety of conditions, but are most abundant in the tropics.

With Genomes, Bigger May Really Be Better:

Biologists analyzing DNA in search of the molecular underpinnings of life have consistently favored species with small genomes, which are cheaper to sequence and lack the repetitive “junk” that clutters bigger genomes. But a new study by Howard Hughes Medical Institute scientists suggests that when it comes to figuring out how genes are controlled, bigger genomes are much more useful.

Following trends is a lifesaving instinct, at least for birds, and provides clues that can be applied across the animal kingdom. New research from Université de Montréal published in Biology Letters, shows that Herring and Ring-billed gulls not only watch their neighbours – they mimic their behaviour to assure their survival. Contrary to previous beliefs, this study suggests that animals don’t necessarily act independently and that they cue on reactions from other members of their group.

‘Undesirable’ Evolution Can Be Reversed In Fish, By Letting The Big Ones Go:

“Undesirable” evolution in fish – which makes their bodies grow smaller and fishery catches dwindle — can actually be reversed in a few decades’ time by changing our “take-the-biggest-fish” approach to commercial fishing, according to groundbreaking new research published by Stony Brook University scientists.

Select Roses Survive With Minimal Care:

Roses have long been a favorite of gardeners, but they often require a lot of work to thrive. And the emphasis on organics has more home gardeners concerned about the environment and reluctant to use pesticides.

New Clues About Mitochondrial ‘Growth Spurts’:

Mitochondria are restless, continually merging and splitting. But contrary to conventional wisdom, the size of these organelles depends on more than fusion and fission, as Berman et al. show. Mitochondrial growth and degradation are also part of the equation.

Two Food Additives Have Previously Unrecognized Estrogen-like Effects:

Scientists in Italy are reporting development and successful use of a fast new method to identify food additives that act as so-called “xenoestrogens” — substances with estrogen-like effects that are stirring international health concerns.

Futuristic Seafood: Raising Delicious Cobia And Pompano Fish — Inland:

Two saltwater superstars–cobia and Florida pompano–are regarded by connoisseurs as being some of the world’s best seafood. Both cobia (pronounced COE-bee-uh) and pompano (POM-puh-no) have firm, mostly white flesh that’s perfect for grilling, pan-frying or baking.

Trauma in Dogs and Cats: Novel Veterinary Procedure Detecting Life-threatening Injuries Touted:

The incidence of pneumothorax (PTX), or collapsed lung, among dogs and cats with blunt and penetrating trauma has been reported to range from 13 – 50 percent, with mortality rates ranging from 10 – 18 percent. In people, PTX is reported to be the most preventable cause of death in trauma patients.

New Soldier In War On Cancer: The Blind Mole Rat:

If someone ever calls you a “dirty rat,” consider it a compliment. A new discovery shows that cellular mechanisms used by the blind mole rat to survive the very low oxygen environment of its subterranean niche are the same as those that tumors use to thrive deep in our tissues.
