Listening to bees helps detect diseases

Eavesdropping on the buzzing of honey bees in their hives can reveal whether they are suffering from disease, scientists have claimed.

Researchers have found that they can detect subtle changes in the vibrations honey bees use to communicate with each other that indicate how healthy the insects are, the Telegraph reported.

Growing levels of disease, including a deadly parasite known as verroa mite, have taken a devastating toll on honey bee colonies, causing numbers of the insects in Britain to more than halve in the past 25 years.

Dr Martin Bencsik, a physicist at Nottingham Trent University, is now developing a device that can automatically detect the signs of disease in bees to give bee keepers an early warning of any infections in a colony and hopefully allow them to take action.
It detects distinct vibrations that the insects pass through the honeycomb in their hives to warn others in the colony about possible threats.

Eating lunch at 3 pm can help reduce weight

People lost 25 percent less weight if they ate lunch after 3 pm, a new study has found.
The study followed 420 Spanish people in a weight-loss program, Fox News reported.
However, the study doesn’t mean that you should eat earlier-in fact, you might want to do the opposite.

The Spanish are known for making a late lunch the biggest meal of the day, so the study’s authors couldn’t say that the findings would apply in the US. That said, other new research does show that when you eat-not what you eat-can turn on your body’s fat-fighting genes.  Until Mr. Thomas Edison lit our evenings, we rose with the sun, worked, ate, played, and slept. That’s what your hormonal cycle is designed for.
Now, our schedules are more like eat-work-eat-work-eat-sleep.

The average American eats 3.5 times per day, according to research from the National Institute of Environmental Health Sciences-and that’s only counting meals of at least 70 calories or more, not the handful of chips you grab between commercial breaks.
Olive oil could hold key to beating Alzheimer's
Scientists in America have found that oleocanthal – a compound which gives olive oil its peppery “bite” – helps to destroy the toxic proteins that are thought to cause Alzheimer’s disease.

The researchers believe that the naturally-occurring antioxidant could become a key ingredient in powerful new drugs to fight dementia, the Daily Express reported. They also suggested that a Mediterranean diet could help people cut their risk of developing Alzheimer’s.

They noted that rates of the disease and other forms of dementia are far lower in Mediterranean countries, where extra-virgin olive oil is a staple part of the diet.
High consumption of oleocanthal is believed to help “shuttle out” destructive molecules of the protein amyloid beta from the brain.

The sticky protein forms harmful “plaques” which kill off nerve cells and eventually stop one part of the brain talking to the other, causing devastating symptoms such as memory loss and confusion. Amyloid beta is thought to build up in the brain for at least a decade before the first outward signs of dementia are seen. Finding ways of preventing it from forming plaques is seen as the key to wiping out Alzheimer’s. In the latest study, scientists tested oleocanthal on mice and cells taken from them. The compound was found to boost production of two proteins and key enzymes critical in removing amyloid beta from the brain by stopping it from clinging on to nerve cells.
