2 of 3: We've been enjoying watching Gary the octopus grow up and thrive. The team here at Goat Island Marine Discovery Centre, including Angela Rapson, @ashley_flood, @jade_dudley, Fraser Stobie, Sarah Wilson and Captain Dr T. Haggitt, make sure that Gary gets lots of interesting activities and toys to satisfy his active mind. Here is Gary giving Tom a high-five...not really: octopuses are naturally curious, and use the suckers on their arms to taste, smell and feel their environment. Also, these suckers are incredibly strong! (Read more: https://blogs.scientificamerican.com/…/octopus-suckers-hav…/) We're encouraging Gary to get used to interacting with us, and as he gets bigger it will be easier for us to confirm if Gary is indeed, a 'he'. A male cephalapod would have a specialized arm, called a 'hectocotylus', which is a specially adapted arm used to pass sperm on to the female. In octopuses, the hectocotylus is usually the third right arm. All we need is to be able to get up close and see if the tip of Gary's third right arm looks 'different' from the others! This gripping tale is to be continued... Have a great day ahead! Candace Loy PS. Looking for fun and educational school holiday programs?

Water On The Moon Confirmed, And There May Be Much More Than We Thought

NASA's intriguing announcement last week that it would reveal an 'exciting discovery about the Moon' led to a lot of speculation on what this big discovery

A British-led expedition to the Arctic has made a depressing discovery in the middle of the Arctic Ocean: polystyrene.

The researchers found chunks of plastic and polystyrene on ice floes in the ocean where previously they hadn’t been able to even access due to sea ice.

This is the furthest north of any ocean that plastic detritus has been discovered, only 1,000 miles from the North Pole. It would seem there really is no getting away from plastics in the oceans.

The researchers were part of Pen Hadow’s Arctic Mission to sail to the North Pole, collecting important data along the way, which is still taking place. British explorer Hadow is the only person to have ever trekked solo from Canada to the geographic North Pole without resupply.

The team wasn’t expecting to find polystyrene so far from land, but then they weren’t expecting to be able to access an area that is usually covered by ice all year round.

“For the 25 years I have been exploring the Arctic I have never seen such large and very visible items of rubbish,” said Hadow, the Guardian reports. “The blocks of polystyrene were just sitting on top of the ice.”

One of the large pieces they found was on an ice floe in the middle of international waters in the central Arctic Ocean region – further than anyone has ever got before without icebreakers.

“Finding pieces of rubbish like this is a worrying sign that melting ice may be allowing high levels of pollution to drift into these areas,” marine biologist Tim Gordon of Exeter University, and one of the researchers, added. “This is potentially very dangerous for the Arctic’s wildlife.”

Many rivers – which accumulate and distribute plastic pollution – flow into the Arctic. Before now, it usually got trapped in the ice. Not nice, but at least it’s not going anywhere. Now the sea ice is melting, the new danger is that the pollution, especially tiny pieces like microplastics, will be swept further out to sea.

The discovery of the plastics so far north in this expedition has confirmed this danger. With projections showing that the Arctic will be ice-free in summer by 2040, with easier access opening up human exploration – and exploitation, in many forms – the researchers are worried about the previously untouched area for both flora and fauna.

“The Arctic Ocean’s wildlife used to be protected by a layer of sea ice all year round,” Gordon said. “Now that is melting away, this environment will be exposed to commercial fishing, shipping, and industry for the first time in history. We need to seriously consider how best to protect the Arctic’s animals from these new threats.”

Scientists at the French National Center for Scientific Research have used nerve stimulation to induce signs of consciousness in a man who has been in a vegetative state almost half his life. The unfortunate individual is still far from complete wakefulness, but his case demonstrates consciousness can be restored after a much longer time than previously thought.

The vagus nerve connects the brain to the gut, along with other parts of the body. Stimulation has been shown to sometimes offer benefits to people with depression or epilepsy. It’s also known to have a role in the process of waking from sleep, and in keeping us alert. Putting these pieces together, Dr Angela Sirigu wondered if it could play a role in restoring consciousness to patients with unresponsive wakefulness syndrome.

The longer a person is in a vegetative state, the less likely they are to recover, particularly of their own accord. In order to be confident any responses were a result of their intervention, Sirigu sought the patient who had gone the longest without improvement. The chosen individual had a car accident at the age of 20, and remained unresponsive 15 years later.

After a month of stimulation of the vagus nerve with a current of around a milliamp, the man was able to turn his head on request. His eyes could follow a moving object and he appeared to stay awake longer when read to. He also spontaneously opened his eyes wider when someone’s head rapidly approached his face.

Sirigu reports in Current Biology that electroencephalogram (EEGs) also showed increased brain activity, including in the theta waves used to define the differences between states of consciousness. Metabolic activity was found to have increased in the cortex and sub-cortex, indicating a need for more fuel among brain cells.

These tests led doctors to upgrade the patient’s status from unresponsive to “minimal consciousness”, and Sirigu to conclude in a statement: “Brain plasticity and brain repair are still possible even when hope seems to have vanished.”

PET images compare brain activity by region before and three months after vagus nerve stimulation

A year without increases in consciousness has been identified as the point where waking is unlikely to occur, and after 15, progress is rare indeed.

The vagus exerts its influence on the brain by inducing the release of the hormone norepinephrine (also known as noradrenaline). Norepinephrine also acts as a neurotransmitter, enhancing information sharing between brain regions. Sirigu and co-authors note that, besides bringing hope to the loved ones of those who are in states of limited consciousness, their observations provide insight into where consciousness lies within the brain.

The work, they write, identifies the parietal cortex as “a major player in guiding the expansion of neural activity across brain regions”, promoting further study on this part of the brain.
