Obesity now affects more than 600 million people worldwide and is increasingly becoming a serious public health problem. But despite this, we still don't completely understand what causes people to become obese. Scientists know it's an interaction between our genes and our environment, including the unique environment of microbes that live in our guts, but they are still unsure of how exactly these factors come together to cause someone to become overweight and eventually obese.

Runways are a hassle. Long, flat strips of unobstructed land are work to defend at the best of times, and can't always be found in rugged terrain or on small islands. Yet having a fixed-wing plane fly air support is useful, because plane bodies are faster and much more efficient than helicopters. What's the Marine Corps to do?

The Three Gorges Dam stands 185m high and 3,035m wide. Hydropower projects have had huge impacts on the Yangtze. The dam was designed to benefit people by controlling floods, generating power and aiding navigation, but it has upset the natural flow of the river. WWF and others are working with the operators of the Three Gorges Dam to ensure enough water is being released at key moments, thereby restoring the natural pulse of the river and supporting the needs of wildlife downstream.

For certain species of spider, sex culminates with the male getting eaten. But not all spiders go meekly into the jaws of their partners. Some males tie their mates up to avoid becoming a meal. Others copulate with females before they have grown into mature sexual cannibals, scientists reported September 20 in the journal Biology Letters.

“Climate change poses a significant and growing threat to national security, both at home and abroad,” declared a memorandum from the White House to the heads of executive departments and agencies. With the United States about to enter its 15th year of fighting against the Taliban in Afghanistan, and with the fight against ISIS in Iraq spilling over into Syria more and more, it may seem odd for the President to direct resources towards a less direct threat. Does it really make sense for the United States military to spend resources on fighting climate change instead of defeating ISIS?

The courtship song of the midshipman fish is a pleasure that can only be enjoyed by night. It turns out that these long, droning hums follow a daily rhythm that is set by light and the hormone melatonin. With enough light, singing fish can be made to quiet down, a condition that is remedied with a boost of melatonin, scientists reported today in the journal Current Biology.

A delivery van is a tiny warehouse on wheels. Away from the conveyor belts and simple machines of a warehouse, humans, usually two of them, do all the rudimentary tasks of delivery: driving, finding the packages in the back, and placing packages on doorsteps. Mercedes-Benz, in collaboration with drone delivery company Matternet, created a concept Vision Van that replaces this routine with an automated system, and adds two drones on top for speedy delivery.

Following my previous post, I’d like to add a bit more to the debate about Brexit and migration. On this issue, a common defence of the Leave campaign is that the central concern was about the need to cut the number of migrants to the UK so as to reduce competition for jobs.

I was musing in the shed when there was this horrid, repeated scratching-on-metal sound through the outside metal wall—the shed making up part of "the wall", the chicken pen fence that separates them from us.I went out.

The big one had been scratching and pecking.They looked up at me and clucked with menace—with the implication that the shed wall noise would continue if I did not meet their demands.I caved. I got a small amount of feed and sprayed it across their yard so they'd be excited about finding it.

the best politicians money can buy ...

Our politicians have sold our country out from under the feet of the citizenry. We are no longer even the primary audience that our politicians are worried about. Policies are now crafted to be suitable to the Murdoch and Fairfax organisations and the big end of town. Exclusively. Common sense does not matter. Nor do Aussie citizens.
