6:59 PM | The Oceans Link to Climate Change
Hold on to your hats folks, we can all agree that most of the concerns about climate change have focused on the amount of greenhouse gases that have been released […]

9:30 PM | The world's oldest genome shows when our ancestors had sex with Neanderthals.
The world's oldest genome shows when our ancestors had sex with Neanderthals. Analysis of a 45,000 year-old femur shows that modern humans and Neanderthals mated 52,000 to 58,000 years ago — a much smaller window than previously estimated (a 49,000 year span). It's the oldest-known human genome ever sequenced, revealing a mysterious population that once spanned northern Asia. Read more...

12:30 AM | Slavery In America: Back In The Headlines
The Slave Trade painted by a French abolitionist artist.By Daina Ramey Berry, University of TexasPeople think they know everything about slavery in the United States, but they don’t. They think the majority of African slaves came to the American colonies, but they didn’t. They talk about 400 hundred years of slavery, but it wasn’t. They claim all Southerners owned slaves, but they didn’t. Some argue it was a long time ago, but it wasn’t. read more

People have survived for centuries on the tiny island of Rapa, carefully managing their resources through an ancient system known as rahui. What lessons does it hold for the rest of the world today?

11:18 PM | October 19, 2014: Creating Electricity From Food Waste, Arresting Poachers and More
This week on National Geographic Weekend radio, join host Boyd Matson and his guests as they unearth the habits of the world's largest-ever carnivore, digest kitchen waste to cook dinner, eat like a 500 year old king, stalk Chernobyl's ruins, trace tree rings' roots, write a novel about elephants with a plot twist, kayak to protest dams, prosecute poachers in Mozambique, and see the unseen as a large format film.

7:20 PM | Ashes And Vegetables: The Diet Of Roman Gladiators Was Rather Poor
Ancient Greeks used onions as a performance-enhancing drug. Roman gladiators ate ashes and vegetables. If common-sense does not tell us that there was no ancient civilization with futuristic technology building pyramids, anthropology certainly can.Historic sources claimed referred to gladiators  as "hordearii" ("barley eaters") because they had an inferior diet, heavy in beans and grains, the hallmark of poor status. Even 2,000 years ago people made fun of vegetarians, it seems. Though the […]

5:48 PM | Manly Men And Feminine Women Are Not Evolutionary Mandates - They Are Urban Ones
It is often believed that masculine men and more feminine women were prized in ancient societies and that modern culture is beyond gender simplifications, but a team of psychologists, anthropologists and biologists that surveyed 12 populations around the world, from the primitive to the highly developed, find that isn't so.read more

4:29 PM | Climate Change: It’s Only Human To Exaggerate, But Science Itself Does Not
Credit: EPABy Rob MacKenzie, University of BirminghamTo exaggerate is human, and scientists are human.Exaggeration and the complementary art of simplification are the basic rhetorical tools of human intercourse. So yes, scientists do exaggerate. So do politicians, perhaps even when, as the UK’s former environment secretary Owen Paterson did, they claim that climate change forecasts are “widely exaggerated”. read more

12:55 PM | People Are More Swayed by Things That Look Sciencey
Anyone who’s paged through a women’s magazine will recognize this strategy: to make a product seem better, surround it with a scientific glow. “Clinical trials show lashes grow up to 400% fuller!” “27% reduction of dark spots in 10 weeks!” “Ceramides!” Does this actually help convince people to hand over their cash? A study using […]The post People Are More Swayed by Things That Look Sciencey appeared first on Inkfish.

6:00 AM | Brian Cox's Human Universe presents a fatally flawed view of evolution
Humans do not stand at the top of a ladder of creation, above the apes and below the angels, superior to all other species When I watched the first episode of Human Universe, a televisual emission on the BBC presented by the ever-lovely Professor Brian Cox, I held my breath. I am usually allergic to tales of The Ascent of Man, but I thought and hoped that wed outgrown the idea of evolution as a linear narrative leading from archaea to astronauts. So I exhaled markedly about halfway through […]

9:17 PM | Emodiversity: A Mix of Emotions Is Healthiest?
“Emodiversity” – a life containing a balance of different emotions – is good for you. So say psychologists Jordi Quoidbach and colleagues in a rather cool new paper (pdf). In two large surveys (with a total of over 37,000 responders), conducted in France and Belgium, Quoidbach et al. show that emodiversity is an independent predictor […]The post Emodiversity: A Mix of Emotions Is Healthiest? appeared first on Neuroskeptic.

8:49 PM | The interdisciplinary continuum in studies of Humanity and the Earth
Sometimes I find it hard to put myself into a subject area box. I was a Geography undergraduate, a Geoarchaeology MSc student, and did a PhD jointly in Chemistry and Archaeology. What does that make me? I used to say I was a geoarchaeologist, applying the methods of geoscience to archaeological questions. But I realised that was too narrow, as even the methods I draw upon vary depending on the question being asked, and indeed a multi-proxy approach is something which I try  to promote. My […]

In human evolution, for example, molecular clocks, when combined with fossil evidence, have helped trace the … Continue reading →

1:00 AM | Societies Where Women Outnumber Men Are Just As Violent
There's long been a common-sense idea — largely untested by science — that having a surplus of men in a society causes more violence. But now we have evidence that this isn't true. Societies where the population is dominated by women are just as violent as ones dominated by men.Read more...
