Most of us now subscribe to the idea that plastic bags are bad for the environment. Hence, droves of people turn up at their local supermarket with a sturdy jute bag in tow. Now, there’s evidence that the items that … Continue reading →... Read more »

Acknowledging that some topics have the ability to furrow brows when it comes to autism research, mercury and autism is becoming something of a frequent talking point on this blog as a function of a whole slew of articles appearing in the peer-reviewed domain. If I were to [very tentatively] summarise the collected literature so far, it would be to say something like:Mosaic of mercury @ Wikipedia (i) there is quite a bit more research to be done on some sources of mercury being 'l........

Lately I've been gearing up for some nano-particle research, and so I've been doing a lot of reading about very small things. While perusing the literature, I came across a paper published online in Environmental Science and Technology that takes a look at microplastics.Let’s start with the Great Pacific Garbage Patch, a very good example of this type of marine pollution. This huge collection of marine debris in the North Pacific Ocean is created by an ocean gyre, a stable circular ocean curre........ Read more »

It may be time to leave “busy as a bee” with other dubious animal similes like “happy as a clam” and “drunk as a skunk.” That’s because some bees, it turns out, aren’t all that busy.

Close-up view of the meninges surrounding the brain.
The term meninges comes from the Greek for "membrane" and refers to the three membranes that surround the brain and spinal cord. The membrane layers (discussed in detail below) from the outside in are the: dura mater, arachnoid mater, and pia mater. Their positioning around the brain can be seen in the image to the right.What are they and what do they do?The brain is s........ Read more »

No matter how careful we are, at some point in all of our lives we will develop sunburn. Despite all of the NHS campaigns and warnings that sun damage can cause skin cancer, many of us will know at least one person who forgoes using suncream and lets themselves bake in the sun in the quest for the perfect summer glow. But what is sunburn? And why is it so dangerous? First we need to take a look at our skin.... Read more »

How many times can you say the word “gonad” in a sentence without giggling? If the answer is one, then I congratulate you on turning thirteen. If the answer is many, then you must be a biologist. Biologists appreciate the value of a good gonad, and so should you. The gonad of the worm C. elegans serves as an important model in which to study tissue organization and development, as you’ll see in the paper that accompanies today’s image. At the end of cell division, cytokinesis typical........ Read more »

There has been a rash of great white shark sightings and attacks in the news recently. But, have attacks and sightings remained constant, or are they really on the increase? Several news studies provide evidence that the Marine Mammal Protection Act of 1972, the ban on commercial whaling in 1982, and the ban on great white hunting in 1997 have increased the number of sharks on the coasts of the North America and Australia. In addition, great white sharks live much longer than previously assumed,........ Read more »

Yeah, I know you know. There’s a lot of genomics and proteomics data coming out every day–some of it in the traditional publication route, but some of it isn’t–and it’s only getting harder and harder to wrangle the useful information to access the signal from the noise. I can remember when merely looking through the […]... Read more »

Loud noises are common in nature. New research is giving clues as to how and why animals make such noise. A new study investigates the reasons that howler monkeys howl. Protection and marking territory are main reasons, including for protection of infants or feeding areas.
A slightly older study notes that blue whale song has become lower in pitch since the whaling ban. The authors suggest that the reason for this may be that males don’t have to sing as loud (higher frequencies are loud........ Read more »

I admit to some head scratching when I first read the paper by Aoife O’Donovan and colleagues  reporting that among war veterans of the Iraq and Afghanistan campaigns, "trauma exposure and PTSD [post-traumatic stress disorder] may increase risk of autoimmune disorders".It wasn't that I didn't believe the results, but rather that the idea that a physical event with a psychological consequence could impact on a somatic condition with an autoimmune element to it seemed to open u........
