Patrick Randolph-Quinney, University of Central Lancashire and Anthony Sinclair, University of Liverpool This article was originally published on The Conversation. Read the original article. Just 20 years ago, many archaeologists believed there was a “human revolution” 40,000-50,000 years ago during which modern behaviours such as symbolism, innovation and art suddenly arose. This was thought … Read More

Is it a shrimp? Is it a prawn? No – it’s Super Crayfish! - BioBlog

Alison Campbell Feb 12, 2018

Polyploidy – the duplication of chromosome sets – is relatively common in plants, and can result in the development of new species. (Many modern food crops are polyploids.) It’s much less common in animals, although found in some frogs and salamanders (amphibians) and leeches (annelids). So it was with a mix of excitement, surprise, and alarm that … Read More

How palaeolithic humans shaped the modern genome - News

Jean Balchin Jan 31, 2018

When we think about our ancestry, we think about our grandmothers and grandfathers – and, if we have photo albums nearby, or a family member interested in genealogy, we might know a bit more about our great-grandmothers, great-grandfathers, and so on. I remember traveling around Scotland a few years ago, and chancing upon a small churchyard. Every second gravestone, most … Read More

Ange Palmer: Why I Feel So Good About Climate Change - Hot Topic

Gareth Renowden Jun 26, 2014

I have been marinating in the meaty world of climate change for a good five years now. I’ve been on a wild ride as a film maker producing a documentary called 2 Degrees (that’s the trailer above). Our film looks at the flaws in the UN climate negotiation process through the gritty lens of climate […] … Read More

Out of Africa: Nigerian environment minister warns of devastating climate impacts - Hot Topic

Bryan Walker Jun 09, 2014

The government in New Zealand may make soothing noises about climate change impacts, but that is not an option for the Minister of Environment in Nigeria, Mrs Laurentia Mallam. She issued this chilling warning about the impacts of sea level rise a few days ago: “Studies have projected that with an accelerated sea level rise […] … Read More

And now for some science… the marvels of skin - Infectious Thoughts

Siouxsie Wiles Jun 06, 2014

Apologies for the lack of actual science posts recently. Let’s see if we can remedy that! Last month I had the great privilege of interviewing skin cancer surgeon Dr Sharad Paul* for a session at the Auckland Writers Festival. We talked about his recent book Skin – A Biography, published in 2013 by Fourth … Read More

Protest, procrastination and #wtf? - Hot Topic

Cindy Baxter Nov 22, 2013

When people just arriving in Warsaw over the last few days ask me how long I’ve been here, my general response has been “all my life.” That’s what it feels like.  You’d think I’d be used to this, it being my 11th COP. But there’s nothing like that special feeling of tiredness having been in a hideous, […] … Read More

Turning drones into doves - Ariadne

Robert Hickson Nov 07, 2013

A quick, somewhat tangental, follow-on from yesterday’s post. I came across this quote by  Simon Johnson in a FastCompany article: “The Nokia 1100 is the Kalashnikov of telecommunication–a complex technology in a simple device,” Now that’s a powerful image. He is of course referring to the extra-ordinary benefits and influence mobile phones are bringing to many African communities. Read More

The awakening lions – Africa in 85 years - Ariadne

Robert Hickson Jul 18, 2013

While there is a lot of attention on the rising power of China, the stuttering development of India, and the potential of Brazil and Russia, think ahead to Africa. The Washington Post has written a nice piece about the rising demographic might of Africa, based on UN projections. Barring major catastrophes (famine, disease, war, environmental collapse, … Read More
