Air pollution is causing your baby problems, but breastfeeding can help

by Dr. Jekyll in Lunatic Laboratories

Aitana Lertxundi has conducted her research work within the framework of the INma (Childhood and Environment) programme led by Jesús Ibarluzea of the Department of Health of the Government of the Basque Autonomous Community (region). The aim is to assess how exposure to environmental pollution during pregnancy affects health and also to examine the role of diet in physical and neurobehavioural development in infancy. The study focusses on the repercussions on motor and mental development during........ Read more »

Evaluation of a spatial ecosystem model: predictions and data

by sceintists from the Marine group at CEES in Marine Science blog




Spatial Ecosystem models can be useful but need to be validated with data. Our study validates for the first time the spatial version of the commonly used Ecopath with Ecosim ecosystem modelling suite. We find that spatial distribution of fish species is well predicted by the model, but fishing effort distribution is not.

Tiny grains of lithium dramatically improve performance of fusion plasma

by Dr. Jekyll in Lunatic Laboratories

While fusion might still be a far off dream, a new discovery may help bring that dream closer to reality. Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that could quicken the development of large scale fusion energy. The scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically....

Why Some Bugs Are Attracted to the Wrong Species

by Elizabeth Preston in Inkfish



The squash bug mating orgies that biologist Christine Miller began noticing in gardens around Gainesville were nothing unusual. Dozens of insects were crowded together, the petite males along with the bulkier females, to search for partners. The unusual thing was that some males were copulating with females of the wrong species—apparently, they found them irresistible.

When Jen Hamel arrived at Miller's University of Florida lab to do her postdoctoral research, she took up the mystery o........ Read more »

The Ugly Butterfly Gets The Girl

by Mark Lasbury in As Many Exceptions As Rules

A current theory is that humans (and other animals) perceive symmetry as beauty and is desirable in a mate. Symmetric bodies and faces are correlated with strength, overall health, facial beauty, and dancing ability, but also with extramarital affairs. On the other hand, on butterfly thrives on ugliness. Asymmetric wings actually help males fly better during sexual competitions and gives them a reproductive advantage.... Read more »

‘Water, water, everywhere, Nor any drop to drink’ – Safe drinking water and Adequate sanitation are indispensable for eradicating Cholera

by Sarah Stephen in An ecological oratorio

What has Cholera to do with environment? Absolutely everything!  In this post, we look at why clean water and safe sanitation is essential for eradicating this dreadful disease from our planet. Access to clean drinking water and safe sanitation could eradicate cholera. (Image - Sam Stephen) Cholera, an acute intestinal infection caused by ingestion of food or liquids contaminated with the bacterium Vibrio cholerae, elicits the same fear today, as it did in the past. Although cholera has aff........ Read more »

Which is most valuable: Gold, cocaine or rhino horn?

by Dr. Jekyll in Lunatic Laboratories

Many of the world’s largest herbivores — including several species of elephants, rhinoceroses, hippopotamuses and gorillas — are in danger of becoming extinct. And if current trends continue, the loss of these animals would have drastic implications not only for the species themselves, but also for other animals and the environments and ecosystems in which they live, according to a new report by an international team of scientists....

Nature's natural fix to the ticking carbon time bomb in the peatlands

Peatlands have long been seen as a dangerous store of carbon that could be released as glaciers melt and temperatures increase. But new research suggests Nature has some natural adaptations at hand to prevent such a release from occurring!... Read more »

GMO beef with the heart benefits of fish, why not?

by Dr. Jekyll in Lunatic Laboratories

Sometimes you just want beef, but beef is high in omega-6 fatty acids and low in the omega-3 type. Conversely, different types of fish are high in omega-3, but we all know they don’t compare to that tasty burger flavor. So what’s a beef lover to do, well if you’re in China you might have some options! Chinese scientists have reared beef rich in the beneficial fatty acids associated with fish oils.... Read more »

Monkey Fever Disease in South India: Some recommendations for its management.

by Sarah Stephen in An ecological oratorio

Macaca radiataThe Western Ghats is a mountain range that runs parallel to the western coast of the India starting near the border of the states of Gujarat and Maharashtra and running through Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu states ending at Kanya Kumari, the southern tip of India. The forests in the Western Ghats are unique in that they are some of the best representatives of non-equatorial tropical evergreen forests.

Nanoparticles in products can significantly alter normal gut microbiome

by Dr. Jekyll in Lunatic Laboratories

Nanoparticles, it’s the new buzzword that cosmetics and even consumer “anti-aging” products use to promote their brand. As the word suggests, nanoparticles are small and it shouldn’t be too surprising that these nanoparticles are causing problems in nature because of their prevalence. In that light, it might not be a surprise that there could also be some serious health issues associated with these nanoparticles.... Read more »

Plants Aren’t Just Male Or Female

by Mark Lasbury in As Many Exceptions As Rules

It’s hard enough to believe that flowering plants have different sexes, but how about plants that have three sexes? One trioecious plant varies it sex ratio depending on how much water is around, while another only shows three sexes when it lives near a particular bat. But most amazing, man made the papaya into a three-sex plant. Your tropical fruit salad is made with a hermaphrodite.... Read more »

Fracked, shale-drilling additives in drinking-water taps near leak

by Dr. Jekyll in Lunatic Laboratories

Shale oil has helped the US see lower gas prices and even an opportunity to start exporting. However, it isn’t as great as it might sound, hydraulic fracturing — also known as fracking — has been scrutinized by environmentalists since it’s inception. As it turns out, for good reason, substances commonly used for drilling or extracting Marcellus shale gas foamed from the drinking water taps of three Pennsylvania homes near a reported well-pad leak, according to new analysis from a team of........

Lizards in Long-Term Relationships Can Skip the Foreplay

by Elizabeth Preston in Inkfish



Why would two stubby-legged, blue-tongued Australian reptiles want to stay together not just for a mating season, but for decades? A 31-year study of the reptiles has suggested an answer. While newly formed couples are still getting to know each other, lizards in long-term relationships can start mating earlier in the season. And dispensing with the foreplay might give them a reproductive advantage over their casually dating neighbors.

Tiliqua rugosa is a species of blue-tongued skink tha... Read more »

Pesticides alter bees’ brains, making them unable to live and reproduce adequately

by Dr. Jekyll in Lunatic Laboratories

A new report suggests that a particular class of pesticides called “neonicotinoids” wreaks havoc on the bee populations, ultimately putting some crops that rely on pollination in jeopardy. Specifically, these pesticides kill bee brain cells, rendering them unable to learn, gather food and reproduce. The report, however, also suggests that the effects of these pesticides on bee colonies may be reversible by decreasing or eliminating the use of these pesticides on plants pollinated by bees and........

The Flower Child Must Be Confused

by Mark Lasbury in As Many Exceptions As Rules

Very few animal species have true hermaphrodites, but over 90% of flowering plants are bisexual. Even though the rest are exceptions, they aren’t all the same type of exception. Some plants are male and some are female all the time, but some change sex every morning they flower. And maple tress can decide to be male or female for a whole year and then change their mind for next year.... Read more »
