Getting a glimpse inside the moon

New research from University of Alberta physicists provides the first-ever model of our Moon's rotational dynamics, taking into consideration its solid inner core. Their model helps to explain why, as seen from Earth, the Moon appears to wobble on its axis, according to Science Daily.

The answer, said physicist Mathieu Dumberry, lies in the complex geometry of the Moon's orbit, locked in what is known as a Cassini state.

"The Moon goes around the Earth, but its orbit is inclined by about five degrees. But just like the Earth's rotation axis is inclined by 23.5 degrees in space, the Moon's rotation axis is also inclined, by about 1.5 degrees," explained Dumberry, associate professor in the Department of Physics. "Over one orbit, it points at the same direction in space -- which is in the same plane as the normal to the orbit of the moon. This defines a Cassini state."

This type of lunar orbit was first observed by Giovanni Cassini more than four centuries ago. Since that time, the complex mathematical and physical elements of the Cassini state have been examined by scientists around the world. But what makes this model unique is accounting for a solid inner core at the centre of the Moon.

Brainwaves suppress obvious ideas to help us think more creatively

The human brain needs to suppress obvious ideas in order to reach the most creative ones, according to scientists at Queen Mary University of London and Goldsmiths, University of London.

Creativity requires us to break away from more common and easily reached ideas but we know little about how this happens in our brain, according to Science Daily.

A new study, shows that brainwaves play a crucial role in inhibiting habitual thinking modes to pave the way to access more remote ideas.

Great apes and ravens DON'T plan like humans: Researchers claim the animals can make plans 'without thinking'

Ravens and great apes may not be quite as smart as we think.

Researchers have found that while they are able to plan ahead, it does not require thinking.

Instead, they can make plans instinctively through prior experiences, according to Daily Mail.

'Some researchers have suggested that planning in great apes and ravens develops through thinking, that they simulate future scenarios and make decisions based on such mental simulations,' said Johan Lind, associate professor in Ethology, at Centre for Cultural Evolution, Stockholm University, author of the study. 

The potentially deadly bacterium that's on everyone's skin

Forget MRSA and E. coli. There's another bacterium that is becoming increasingly dangerous due to antibiotic resistance -- and it's present on the skin of every person on the planet, according to Science Daily.

A close relative of MRSA, Staphylococcus epidermidis, is a major cause of life-threatening infections after surgery, but it is often overlooked by clinicians and scientists because it is so abundant.

Researchers from the Milner Centre for Evolution at the University of Bath warn that the threat posed by this organism should be taken more seriously and use extra precautions for those at higher risk of infection who are due to undergo surgery.

To predict the future, the brain uses two clocks

That moment when you step on the gas pedal a split second before the light changes, or when you tap your toes even before the first piano note of Camila Cabello's "Havana" is struck. That's anticipatory timing.

One type relies on memories from past experiences. The other on rhythm. Both are critical to our ability to navigate and enjoy the world, according to Science Daily.

New University of California, Berkeley, research shows the neural networks supporting each of these timekeepers are split between two different parts of the brain, depending on the task at hand.
