Earliest animal footprints ever found -- discovered in Nevada 
The fossilized trail of an aquatic creature suggests that animals walked using legs at least 30 million years earlier than had been thought.

Decline in Alaskan sea otters affects bald eagles' diet
Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse. Scientists are finding, however, that sea otters can have even farther-reaching effects that extend to terrestrial communities and alter the behavior of another top predator: the bald eagle.

Models of eel cells suggest electrifying possibilities
Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers takes it to a cellular level. Applying modern engineering design tools to one of the basic units of life, they argue that artificial cells could be built that not only replicate the electrical behavior of electric eel cells but in fact improve on them.

Sea Turtles FeeBee and Milton to be Released with Satellite Tracking Device
Two six-year-old Loggerhead turtles have grown large enough to be released into the waters of Florida at the end of this month. Feebee and Milton were hatched in July 2002 from two separate nests, and conservation scientists will be monitoring them closely by using satellite tags to learn more about their behavior and movements.

Simple twists of fate
A novel Brandeis University study this week in PLoS Biology reports on some of the molecular gymnastics performed by a protein involved in regulating DNA transcription. Using state-of-the art tools, researchers observed the shape and behavior of individual DNA molecules bent into tight loops by Lac repressor, a protein from the bacterium E.coli that switches on and off individual genes.

Biophysicists create new model for protein-cholesterol interactions
Biophysicists at the University of Pennsylvania have used 3,200 computer processors and long-established data on cholesterol's role in the function of proteins to clarify the mysterious interaction between cholesterol and neurotransmitter receptors. The results provide a new model of behavior for the nicotinic acetylcholine receptor, a well studied protein involved in inflammation and disease

Mapping the neuron-behavior link in Rett Syndrome
A link between certain behaviors and the lack of the protein associated with Rett Syndrome – a devastating autism spectrum disorder – demonstrates the importance of MeCP2 (the protein) and reveals never-before recognized functions associated with aggression and obesity, said researchers at Baylor College of Medicine in a report in the current issue of the journal Neuron.

What Goes Into Naming A New Species? A Lot
When someone finds an animal, vegetable or mineral new to science, the discoverer gets the privilege of giving it a name. Most of the time, it's done soberly, responsibly and carefully — but not always.

Culture greatly shapes young people's drinking habits
Whether young people get drunk as a purposeful behavior or as an unintended consequence depends on what country they live in, according to new research on young people in seven countries. The research finds that young people's views on alcohol and drunkenness were influenced more by culture than by factors such as age and sex.

Is that song sexy or just so-so?
Why is your mate's rendition of Marvin Gaye's "Let's Get it On" cute and sexy sometimes and so annoying at other times? A songbird study conducted by Emory University sheds new light on this question, showing that a change in hormone levels may alter the way we perceive social cues by altering a system of brain nuclei, common to all vertebrates, called the "social behavior network."

'Buckyballs' have high potential to accumulate in living tissue
Research at Purdue University suggests synthetic carbon molecules called fullerenes, or buckyballs, have a high potential of being accumulated in animal tissue, but the molecules also appear to break down in sunlight, perhaps reducing their possible environmental dangers.

Plants in forest emit aspirin chemical to deal with stress
Plants in a forest respond to stress by producing significant amounts of a chemical form of aspirin, scientists have discovered. The finding opens up new avenues of research into the behavior of plants and their impacts on air quality, and it also has the potential to give farmers an early warning signal about crops that are failing.

No helicopter moms among mutant mice
First, he discovered a gene that controls innate fear in animals. Now Rutgers geneticist Gleb Shumyatsky has shown that the same gene promotes "helicopter mom" behavior in mice. The gene, known as stathmin or oncoprotein 18, motivates female animals to protect newborn pups and interact cautiously with unknown peers.

Cryopreservation techniques bring hope for cancer victims and endangered species
Emerging cryopreservation techniques are increasing hope of restoring fertility for women after diseases such as ovarian cancer that lead to destruction of reproductive tissue. The same techniques can also be used to maintain stocks of farm animals, and protect against extinction of endangered animal species by maintaining banks of ovarian tissue or even nascent embryos

Potential remedy for the 'mental fog' in cancer patients
Cancer patients have complained for years about the mental fog known as chemobrain. Now in animal studies at West Virginia University (WVU), researchers have discovered that injections of N-acetyl cysteine (NAC), an antioxidant, can prevent the memory loss that breast cancer chemotherapy drugs sometimes induce.

Researcher develops novel method to grow human embryonic stem cells
The majority of researchers working with human embryonic stem cells (hESCs) – cells which produce any type of specialized adult cells in the human body – use animal-based materials for culturing the cells. But because these materials are animal-based, they could transmit viruses and other pathogens to the hESCs, making the cells unsuitable for medical use.
