Have you ever considered a world without elephants? This is a world we’re heading toward with the profound level of poaching that has occurred. As a result of almost institutionalized poaching over many decades, we have decimated the population of wild African elephants to between 400,000 and 600,000 individuals.
The Ig Nobel Prizes is one of my favourite events of the year, and this year the winning research is particularly great. On the 14th September, The 27th First Annual Ig® Nobel Prize Ceremony & Lectures took place at Harvard University in Massachusetts. In case you’re not familiar with the awards, they were set up […]
I’d like to talk about a problem. It might seem like quite a small problem, but it’s a pervasive one. That problem, is salad. Yes, that’s right, I said salad. Not high on the list of major world perils, but perhaps it should be. I mean, for starters, it’s everwhere. Lurking in every supermarket-bought sandwich, […]
It has become something of an annual tradition that I produce an advent calendar each year with facts, interesting links and videos. Consider it a little festive treat for your brain :) Here is your 2016 advent calendar – check out the doors that are already open, and come back each day for a new treat!
The spread of non-native species across the globe is a major concern – species out of their natural range can cause millions of pounds of damage, spread diseases to humans and livestock and threaten native wildlife. They are a huge financial burden to control, but almost impossible to eradicate. New invasive species reach foreign lands by hitching a ride on our trade routes, so changes to global trade could have serious implications for our economies and our ecosystems.
A fatty diet could change your genetic make-up, priming the immune system and causing clogged arteries.
Epigenetic changes – which often involve adding methyl to particular DNA sequences in a process known as DNA Methylation – can alter gene expression in response to environmental stimuli. The field of epigenetics has excited biologists because it allows animals to adapt their genetics to fit the environment, while also passing some of that experience on to the next generation.
Question: How much of the land on Earth is covered by humans?
Answer: Approximately 10%.
This question is an interesting one because, when my friend asked me the other day, I could tell her confidently that not only did science know the answer, science had multiple different ways to quantify that answer, but that I had absolutely no idea what it was.
Great-tailed grackles are very flexible, quickly learning to associate new cues with food, but new research suggests this doesn’t help them innovate to solve new problems.
I’ve previously blogged on the topic of edible insects, so I was thrilled to hear from Ghergich about their new blog and infographics on the subject. It is great to see real recipes using insects as an ingredient and I’m pleased to see how far the industry has progressed since I wrote my original post. So here’s a guest post for Curious Meerkat by Tafline Laylin for Ghergich.com, with a special introduction by Kaitlyn Blakeley. This article was originally posted on Fix.com.
Thinking about ways to increase your protein intake? You might want to think about bugs.
Yes, that’s right, we said it: Edible insects are an environmentally friendly addition to your dinner plate. How are they environmentally friendly? For starters, they need less water and less feed than traditional sources of protein. They also don’t release the same amount of greenhouse gases and don’t have the same troubling welfare issues as other animals that are harvested for their meat.
What do those cute little baby sea turtles do after their epic sprint to the water? Until very recently, we simply didn’t know. Nobody had been able to study the movement of juvenile sea turtles in natural conditions – they were simply too small and too difficult to track. But a new study reveals for the first time just what the young turtles have been up to in the Pacific ocean – and it shows that they are just as determined and tenacious as they were on land, fighting strong currents to reach their preferred feeding grounds.

I have just finished four weeks of fieldwork collecting insects in Dominica. I can’t really complain about that except that the fieldwork did not follow my usual routine. Generally when employed at The Natural History Museum your fieldwork is either part of a general collecting trip hoping to find as much as possible (work with Dipterists Forum); part of a research focused group (me collecting flies from Potatoes in Peru); or part of a consultancy project (Mosquitoes in Tajikistan). However this trip was different, I wasn’t marauding around the countryside with collector’s glee, this time I had to teach as well as collect.
Habitat disturbance, be that logging, agriculture, or roads and infrastructure, can be hugely damaging to biodiversity. But even after the visible wounds have healed, the genetic scars of past disturbance remain in the genome, according to results from a two-decade-long study of shrubs in Spain.
The effects of habitat disturbance on plants can be seen in the genomes of the next generation, a new study reports for the first time. The team compared the genetic and epigenetic profiles of shrubs (Lavandula latifolia) that had been experimentally disturbed 20 years previously, with those left undisturbed for more than 50 years.
What big eyes you have! The net-casting spider Deinopis spinosa uses it’s enormous eyes to accurately trap prey at night, according to new research.
A new study published in Biology Letters this month shows that net-casting spiders (Deinopis spinosa) use their enlarged, secondary eyes to spot prey in the dark.
