- Dogs 'hardwired' to be jealous wags
Jealousy is not just part of the human condition, a study suggests, it appears to be hard wired into the brains of dogs too.
- Fur seals feel climate impacts
Changes in the Antarctic climate are showing up in the fur seal population, say scientists who have studied the animals for 30 years on the British Overseas Territory of South Georgia.
- Genetic clues to age of first period
The timing of when a girl reaches puberty is controlled by hundreds of genes, say scientists.

- Nearly 50 years of lemur, other primates data now available online
A 48-year archive of life history data for the world's largest and most diverse collection of endangered primates is now digital and available online. The database allows visitors to view and download data for more than 3600 animals representing 27 species of lemurs, lorises and galagos -- distant primate cousins who predate monkeys and apes -- with more data to be uploaded in the future.
- Cost-effective, solvothermal synthesis of heteroatom (S or N)-doped graphene ...
A research team has developed cost-effective technology to synthesize sulfur-doped and nitrogen-doped graphenes which can be applied as high performance electrodes for secondary batteries and fuel cells.
- Natural products from plants protect skin during cancer radiotherapy
Plant-derived natural product chemicals could offer protection to the skin from the harmful effects of gamma radiation during cancer radiotherapy, suggests research.
- New mass map of distant galaxy cluster is most precise yet
Astronomers have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing program, the map shows the amount and distribution of mass within MCS J0416.1-2403, a massive galaxy cluster found to be 160 trillion times the mass of the Sun.
- Background TV can be bad for kids
Leaving the television on can be detrimental to children's learning and development, according to a new study. Researchers found that background television can divert a child?s attention from play and learning. Regardless of family demographics, parenting can act as a buffer against the impacts of background TV, the research team found.
- Rising temperatures can be hard on a dog's life
Veterinarians say it is important to know the signs of heat exhaustion to make sure your pet isn't overdoing it this summer.
- Dream come true for chemists? Creating organic zeolites
Traditionally, zeolites have been derived from inorganic material like silicon or aluminum. For the past several years, one research team has focused on combining zeolites with organic polymers whose main component is carbon, oxygen, hydrogen or nitrogen. A new technique and the new materials it produces can be immediately useful in catalysis and separations for chemicals production and hydrocarbon conversion for energy applications.
- Voice for radio? New research reveals it's in the cords
Unique vocal cord vibration patterns might be the secret behind a good radio voice, new research reveals. The world-first study filmed the vocal folds of 16 male radio performers, including announcers, broadcasters, newsreaders and voice-over artists and found their vocal folds move and close faster than non-broadcasters.
- Discovery is key to metal wear in sliding parts
Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another. The findings could be used to improve the durability of metal parts in numerous applications.
- Tempting people to move for work takes more than dollars
Sufficient financial inducements are one way of encouraging people to move to regional Australia for jobs, but other factors also play a part, according to a new report. "Addressing the demand-side factors, such as matching job seekers' skills and experience to employer requirements, has the potential to improve geographic labor mobility," one investigator said.
- Transforming waste in order to transform people's lives
A team of engineers is turning out automotive trunk liners and living wall planters, among other things, with technology they developed that produces a composite material made of coconut husks combined with recycled plastics.
- Law of physics governs airplane evolution
Researchers believe they now know why the supersonic trans-Atlantic Concorde aircraft went the way of the dodo -- it hit an evolutionary cul-de-sac.
- Technique simplifies the creation of high-tech crystals
Researchers have proposed a method that could allow scientists to customize and grow specialized materials, known as photonic crystals, with relative ease.
- Philosopher uses game theory to understand how words, actions acquire meaning
Researchers are using evolutionary game theory models to understand how words and actions acquire meaning through natural processes, whether through biological evolution, social learning or other adaptive processes.
- Chemists eye improved thin films with metal substitution
Chemists have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.
- Studying estrogens made by the brain may offer new insights in learning and m...
Scientists are exploring whether brain estrogens might represent a new, far more targeted treatment for cognitive and memory problems related to disease and aging.
- Size and age of plants impact their productivity more than climate, study shows
Researchers combined a new mathematical theory with data from more than 1,000 forests across the world to show that climate has a relatively minor direct effect on net primary productivity.
- Stem cells aid muscle repair and strengthening after resistance exercise
By injecting mesenchymal stem cells into mouse leg muscles prior to eccentric exercise, researchers were able to increase the rate of repair and enhance the growth and strength of those muscles in the exercising mice.
- Team finds sea level rise in western tropical Pacific a result of human activity
Study indicates sea levels likely will continue to rise in the tropical Pacific Ocean off the coasts of the Philippines and northeastern Australia.
- Scientists identify four new tuco-tuco species found in Bolivia
A research team has identified four new species of Ctenomys, a genus of gopher-like mammal found throughout much of South America.
