Male, female orangutans look to different mentors for sex-specific ecological knowledge

Male, female orangutans look to different mentors for sex-specific ecological knowledge

Science
May 19 (UPI) -- Young male and female orangutans look to different individuals for sex-specific ecological knowledge as they mature, according to new research. Often, studies of sexual differences focuses on mating behavior and social organization, but field observations suggest male and female orangutans also demonstrate sex-specific foraging and dispersal patterns. Advertisement To better understand how these behaviors are acquired, researchers analyzed 15 years worth of data on dietary and social learning behaviors exhibited by 50 young orangutans living among two different Sumatran populations. Scientists shared their findings Wednesday in the journal PLOS Biology. "In our study we showed that immature orangutans show sex specific attentional preferences when observing role models ot...
Huge knowledge gap over health of soil

Huge knowledge gap over health of soil

Science
A vital knowledge gap about England’s environment has been uncovered by soil campaigners.They have discovered that just 0.41% of the cash invested in environmental monitoring goes on examining the soil.That’s despite the fact that soils round the world – including in the UK – are said to be facing a crisis.The figures are startling: £60.5m goes to monitoring water quality, £7.65m to checking on air – but just £284,000 to auditing soil.The mismatch was revealed in a Freedom of Information (FoI) request by the Sustainable Soils Alliance (SSA). Its director, Ellen Fay, told BBC News: “This figure is staggering – but not surprising. It reflects the widespread under-investment in soil health compared to air and water.

Lack of HIV knowledge revealed by survey raises concern among experts, activists

Health
Dec. 2 (UPI) -- HIV can't be passed from one person to another through a hug, but the reluctance of younger Americans to share the gesture with someone who is HIV positive has raised concerns that additional education on the disease is desperately needed. In a survey conducted by the Prevention Access Campaign, HIV-positive activists and drugmaker Merck, more than one quarter of HIV-negative "Millennials" who responded said they have avoided hugging, talking to or being friends with someone with HIV. Additionally, 30 percent said they would prefer not to interact socially with someone with HIV. Activists involved in the project say the results are evidence that many in the general population -- particularly those between 18 and 36 years of age -- remain poorly informed about the virus an...

Quiz: Test your knowledge of evolution

Even spelling the word, evolution, can be tricky when you're seven, but Sophia tells me confidently that evolution "basically means engineering".And Jack says that sharks are lighter underneath so that "when the sun is on the sea, you can't really see the sharks".He's talking about the fact that sharks have evolved a form of camouflage that helps them sneak up on their prey.At the opening of the new Milner Centre for Evolution at the University of Bath, school children are learning about evolution through the help of cuddly sharks of all shapes and sizes, fruit flies and even a tame owl.Their comments reveal a budding interest and knowledge of evolution - at even a tender age.How much do you know about evolution?
