When Emirati astronaut Sultan Al Neyadi took off on Thursday for the International Space Station, he began an adventure of the kind only a select few ever experience.
But while his time in space will no doubt be exciting, it will pose stresses and strains on body and mind beyond those faced on planet Earth.
For example, astronauts have been shown to lose muscle mass during space flight because the lack of gravity makes tasks less physically demanding.
When you come back to Earth, your body has to readjust how it maintains blood pressure
Nathaniel Szewczyk,
Ohio University
“The new astronaut will expect to lose a very substantial proportion of the mass of muscles,” said Malcolm Jackson, of the University of Liverpool in the UK, who has studied cultured muscle cells sent up to the International Space Station.
“It will start within a few days. That happens despite the fact that the astronauts all have to undertake two hours [of exercise] on the space station each day.
“When they went to the Moon, it was about a two-week trip and when they came back, they had to be lifted from their capsule and were very wobbly.”
Dr Jackson’s work has shown that microgravity on the ISS causes muscle cells to undergo a process akin to accelerated ageing.
Maintain conditioning
Much like professional sportspeople, astronauts have nutritionists and exercise coaches to advise them on how to maintain conditioning.
Normal exercise equipment relies on gravity, but on the ISS, the astronauts push against what are, in effect, large springs, Dr Jackson said.
Tim Peake, the British astronaut who spent six months on the ISS, reported that the soles of his feet become “very smooth and soft” because they are hardly used, while the skin on the tops of the toes hardens because it is often employed by astronauts to hold them down or grab handrails.
Exercise equipment can be bulky, so while it can be accommodated on the ISS, there may be issues with other missions, said Nathaniel Szewczyk of Ohio University in the US, who is also an emeritus professor of space biology at the University of Nottingham in the UK.
“The challenges of proper nutrition and proper activity will become emergent problems as we talk about the Moon and Mars,” he said
On their return to Earth, Dr Szewczyk said astronauts often experienced problems with the vestibular system, which controls balance and spatial orientation. This can cause dizziness and difficulty in standing up, walking and turning corners. Blood pressure may also be affected by the lack of gravity.
“In space, it tends to not have that gravity pull; it tends to accumulate a bit in the head. When you come back to Earth, your body has to readjust how it maintains blood pressure,” Dr Szewczyk said.
Balance and blood pressure issues may only last a couple of days after returning to Earth, but hand-eye co-ordination may take longer to return to normal. Tim Peake said his muscles returned to normal over a matter of weeks.
Vision may be affected by being in space because of “quite significant fluid shifts around the eye”, Dr Jackson said.
Microgravity also causes bone mineral density to fall by between 1 per cent and 2 per cent per month, which could pose particular difficulties for longer missions, with astronauts potentially at greater risk of breakages on returning.
Many of the ways in which being in space affects the body happen because of changes to mitochondria, the tiny, energy-producing structures in the cell.
Dr Jackson described the mitochondria as almost like gravity sensors, and it could be their interactions with the cytoskeleton of cells — the network of protein tubules and filaments that give cells their structure — that causes the larger body to be affected by microgravity.
“That’s one of the things we’re trying to [analyse] in another study — the maintaining of tension. It may lead to ways of thinking about how we could prevent these changes and it may have relevance to ageing on Earth,” he said.
Four phases
Space travel does not affect only the body — there are impacts on the mind too, even though astronauts undergo a rigorous psychological assessment before selection.
Astronauts typically experience four phases during a mission, said Patrick Stacey, a senior lecturer in information management at Loughborough University in the UK, who researches mental and emotional health in space.
The arrival phase may involve difficulties sleeping, irritability and nausea, but this is succeeded by the performing phase, when astronauts begin to operate at a high level as they carry out the various experiments they are responsible for.
However, eventually, perhaps after months, the enduring phase begins, in which morale falls and astronauts may wonder when they are going to see their families again, Dr Stacey said.
“It’s well documented — the third phase is [associated with] low morale, which could affect productivity, but it’s not documented the extent to which it does,” he said.
Fortunately, mood tends to pick up in the leaving phase, when astronauts look forward to seeing their relatives again and being back on Earth.
Efforts are made to promote mental well-being during missions, with astronauts typically having a discussion with a psychologist every two or three weeks, Dr Stacey said.
“They can call their family every few weeks or so, but the family cannot call them,” he added.
In previous missions, there has been tension when astronauts have voiced complaints to one another about their life in space, so now they are strongly encouraged to write down concerns in journals instead of saying them aloud.
Sometimes astronauts have struggled on returning to Earth, among them Buzz Aldrin, who became depressed and experienced alcoholism, and Lisa Nowak, who attacked a woman her ex-boyfriend had become involved with.
Dr Stacey said stress could build up during missions and come out later in these ways, highlighting the importance of using journals to “vent”.

Top tips to avoid cyber fraud
Microsoft’s ‘hacker-in-chief’ David Weston, creator of the tech company’s Windows Red Team, advises simple steps to help people avoid falling victim to cyber fraud:
1. Always get the latest operating system on your smartphone or desktop, as it will have the latest innovations. An outdated OS can erode away all investments made in securing your device or system.
2. After installing the latest OS version, keep it patched; this means repairing system vulnerabilities which are discovered after the infrastructure components are released in the market. The vast majority of attacks are based on out of date components – there are missing patches.
3. Multi-factor authentication is required. Move away from passwords as fast as possible, particularly for anything financial. Cybercriminals are targeting money through compromising the users’ identity – his username and password. So, get on the next level of security using fingertips or facial recognition.
4. Move your personal as well as professional data to the cloud, which has advanced threat detection mechanisms and analytics to spot any attempt. Even if you are hit by some ransomware, the chances of restoring the stolen data are higher because everything is backed up.
5. Make the right hardware selection and always refresh it. We are in a time where a number of security improvement processes are reliant on new processors and chip sets that come with embedded security features. Buy a new personal computer with a trusted computing module that has fingerprint or biometric cameras as additional measures of protection.

From Europe to the Middle East, economic success brings wealth - and lifestyle diseases
A rise in obesity figures and the need for more public spending is a familiar trend in the developing world as western lifestyles are adopted.
One in five deaths around the world is now caused by bad diet, with obesity the fastest growing global risk. A high body mass index is also the top cause of metabolic diseases relating to death and disability in Kuwait, Qatar and Oman – and second on the list in Bahrain.
In Britain, heart disease, lung cancer and Alzheimer’s remain among the leading causes of death, and people there are spending more time suffering from health problems.
The UK is expected to spend $421.4 billion on healthcare by 2040, up from $239.3 billion in 2014.
And development assistance for health is talking about the financial aid given to governments to support social, environmental development of developing countries.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.

Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

Nepotism is the name of the game
Salman Khan’s father, Salim Khan, is one of Bollywood’s most legendary screenwriters. Through his partnership with co-writer Javed Akhtar, Salim is credited with having paved the path for the Indian film industry’s blockbuster format in the 1970s. Something his son now rules the roost of. More importantly, the Salim-Javed duo also created the persona of the “angry young man” for Bollywood megastar Amitabh Bachchan in the 1970s, reflecting the angst of the average Indian. In choosing to be the ordinary man’s “hero” as opposed to a thespian in new Bollywood, Salman Khan remains tightly linked to his father’s oeuvre. Thanks dad.
