Researchers ID gene linked to lung cancer and addiction 
Researchers at Johns Hopkins, as part of a large, multi-institutional study, have found one gene variant that is linked to an increased risk of lung cancer. The study will be published in the April 3 issue of Nature Genetics. They also found that the same gene can influence smoking behavior

British scientists make human-cow embryos
British researchers say they have created embryos using human cells and the egg cells of cows, but said such experiments would not lead to hybrid human-animal babies, or even to direct medical therapies.

Scientists discover 356 animal inclusions trapped in 100 million years old opaque amber
Paleontologists from the University of Rennes (France) and the ESRF have found the presence of 356 animal inclusions in completely opaque amber from mid-Cretaceous sites of Charentes (France).

Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour.

Low oxygen and molybdenum in ancient oceans delayed evolution of life by 2 billion years
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth by nearly two billion years, a study led by UC Riverside biogeochemists has found.

Military action to influence oil-producing nations ineffective, expert says
There is another inconvenient truth about finite resources and human behavior on Planet Earth, an expert on international security and energy says. Trying to influence oil supply with military force in the Middle East is not only ineffective, it also is counterproductive.

Living fossil still calls Australia home
They are separated by a vast ocean and by millions of years, but tiny prehistoric bones found on an Australian farm have been directly linked to a strange and secretive little animal that lives today in the southern rainforests of South America.

Common aquatic animals show extreme resistance to radiation
Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal species studied to date.

Family wealth may explain differences in test scores in school-age children
A new study finds that family wealth might partly explain differences in test scores in school-age children. The study, conducted by researchers at New York University, also found that family wealth is positively associated with parenting behavior, home environment, and children’s self-esteem.

Risky teen behavior may not occur at home or school: but how to track?
How can researchers track where teens go when not in or near home or school to see if this movement has an impact on health-related behavior such as smoking or sexual activity" The answer is through that ubiquitous teen accessory – the cell phone.

Earth's earliest animal ecosystem was complex and included sexual reproduction
Two paleontologists studying ancient fossils they excavated in the South Australian outback argue that Earth’s ecosystem has been complex for hundreds of millions of years – at least since around 565 million years ago, which is included in a period in Earth’s history called the Neoproterozoic era.

Mantis shrimp vision reveals new way that animals can see
Mantis shrimp can see the world in a way that had never been observed in any animal before, researchers report in the March 20th Current Biology, a Cell Press publication. The discovery—which marks the fourth type of visual system—suggests that the ability to perceive circular polarized light may lend mantis shrimp a secret mode of communication.

Emotional 'bummer' of cocaine addiction mimicked in animals
Cocaine addicts often suffer a downward emotional spiral that is a key to their craving and chronic relapse. While researchers have developed animal models of the reward of cocaine, they have not been able to model this emotional impact, until now.

Invading trees put rainforests at risk
To the list of threats to tropical rainforests you can add a new one — trees. It might seem that for a rainforest the more trees the merrier, but a new study by scientists at the Carnegie Institution warns that non-native trees invading a rainforest can change its basic ecological structure — rendering it less hospitable to the myriad plant and animal species that depend on its resources.

Blocking protein kills prostate cancer cells, inhibits tumor growth
Researchers at Jefferson’s Kimmel Cancer Center in Philadelphia have shown that they can effectively kill prostate cancer cells in both the laboratory and in experimental animal models by blocking a signaling protein that is key to the cancer’s growth. The work proves that the protein, Stat5, is both vital to prostate cancer cell maintenance and that it is a viable target for drug therapy.
