It has long been known that biomass burning – burning forests to create agricultural lands, burning savannah as a ritual , slash-and-burn agriculture and wildfires – figures into both climate change and public health but the degree of that contribution had never been comprehensively quantified and when science gets political, people may not always want to discuss the complete set of issues.

An anthropological wave has taken place, first in Asia that has now spread worldwide - humans, the most social species on the planet, have begun to gather in groups and ignore each other while communicating wirelessly with people doing the same ignoring of real people elsewhere.

The trend of sitting inches away on a train from other people and routinely ignoring each other while using social media is a social paradox. Why can such social agents be so antisocial?

Orlando Bloom is feeling stressed. Justin Bieber insulted him in Ibiza (why are they in the same club, much less the same city or even country?) or he insulted Bloom's ex-wife, the model Miranda Kerr, and he lashed out at Justin Bieber. Or tried, the wall of bodyguards that makes Justin Bieber brave made that difficult.

Autism is a neurodevelopmental disorder characterized by impaired social interaction, verbal and non-verbal communication, and by restricted and repetitive behaviors. Diagnosis is solely based on behavioral analysis, biological markers and neurological underpinnings remain unknown, but the search goes on. A lack of a biological underpinning makes the development of therapeutic strategies extremely difficult.   

The insular cortex is an integral "hub", combining sensory, emotional and cognitive content. Not surprisingly, alterations in insular structure and function have been reported in many psychiatric disorders, such as anxiety disorders, depression, addiction and autism spectrum disorders (ASD).

Hibiscus flowers are an iconic symbol of tropical resorts worldwide but some are rather rare. Hawaii's State Flower, Hibiscus brackenridgei, is an endangered species.

Everyone knows of the Hawaiian hibiscus but few are aware of an equally beautiful and intriguing related group of plants known as Hibiscadelphus- literally "brother of Hibiscus".

Brother of Hibiscus is highly endangered. Until recently only one of the seven previously known species remained in its natural habitat, the other having gone extinct. These trees are only known, or were known, from five of the eight main Hawaiian Islands. Two are still alive in cultivation, saved in part because of their beautiful showy blossoms. Several were only known from a single wild tree.

DDT, the first modern pesticide, has been banned in the United States since 1972 but it is still commonly used in places where malaria is prevalent. The United Nations recommends it because it is far less harmful to people than malaria is and remains superior to replacements. Malaria drugs have become less effective over time so it's better kill pests before they infect people.

The Deepwater Horizon oil spill, a BP project in the Gulf of Mexico, began in April of 2010. The oil rig collapsed and it took some three months to cap the gusher. During that, concern was also on how to clean up the over four million barrels of oil in the environment

Among other approaches, the government used the Corexit oil dispersant, which emulsifies oil into balls and microbes, such as the genetically modified marine bacterium Alcanivorax borkumensis and the Colwellia species of bacteria, to consume it. And it worked, but a new paper says some of the more toxic components still remain.

Yesterday I gave a lecture at the 3rd International Conference on New Frontiers in Physics, which is going on in kolympari (Crete). I spoke critically about the five-sigma criterion that is nowadays the accepted standard in particle physics and astrophysics for discovery claims.

My slides, as usual, are quite heavily written, which is a nuisance if you are sitting at the conference trying to follow my speech, but it becomes an asset if you are reading them by yourself post-mortem. You can find them here (pdf) and here (ppt) .

Resistance to artemisinin, the main drug to treat malaria, has become widespread throughout Southeast Asia.

Resistance among the Plasmodium falciparum (P. falciparum) parasites that cause the disease is likely caused by a genetic mutation in the parasites, but a six-day course of artemisinin-based combination therapy, as opposed to a standard three-day course, has proved highly effective in treating drug-resistant malaria cases, according to a study in the New England Journal of Medicine. DDT has also been effective for the last 70 years.

Electronic cigarettes have gained considerable popularity over the past few years - for most they are another form of the nicotine patch, and a way to curb harmful cigarette smoking but critics contend they make smoking cool.

No one thinks they are cool, they are in Google Glass territory among the public, just a moment away from leading to insults, so research instead focuses on the well-documented health benefits of smoking less versus any possible risks.

Governments want to regulate them to generate revenue so the onus is on the industry to try and prove they are safe, an impossible task. Yet if they show they are not harmful, it will be harder to convince the public they should regulate those when alternative medicine is unchecked.
