Poor heart health linked to premature brain ageing, says study

Researchers have identified factors affecting premature ageing of the brain by estimating people’s brain age from scans.

Poor heart – or cardiovascular – health at age 36 predicted a higher brain age later in life, researchers discovered.

The UCL study also found that men tended to have older brains than women of the same age.

According to the study, higher brain age is associated with slightly worse scores on mental cognitive) tests, and also predicted increased brain shrinkage over the following two years.

Researchers suggest this could be an important indicator for people at risk of cognitive decline or other brain-related ill health.

“We found that despite people in this study all being of very similar real ages, there was a very wide variation in how old the computer model predicted their brains to be," said lead author Prof Jonathan Schott, of UCL Dementia Research Centre and UCL Queen Square Institute of Neurology.

“We hope this technique could one day be a useful tool for identifying people at risk of accelerated ageing, so that they may be offered early, targeted prevention strategies to improve their brain health.”

The scientists used an established MRI-based model to estimate the brain age of people on the Alzheimer’s Research UK-funded Insight 46 study, led by Prof Schott.

As they had been a part of the study throughout their lives, scientists were able to compare their current brain ages to various factors from across the life course.

They were all between 69 and 72, but their estimated brain ages ranged from 46 to 93.

The study found that people with worse cardiovascular health at age 36 or 69 had worse brain health, as did those with increased cerebrovascular disease on MRI (relating to blood flow and blood vessels in the brain).

“The Insight 46 study is helping reveal more about the complex relationship between the different factors influencing people’s brain health throughout their life," said Dr Sara Imarisio, head of research at Alzheimer’s Research UK.

“Using machine learning, researchers in this study have uncovered yet more evidence that poorer heart health in midlife is linked to greater brain shrinkage in later life.

“We’re incredibly grateful to the dedicated group of individuals who have contributed to research their entire lives making this work possible.”

The findings are published in The Lancet Healthy Longevity.

Haircare resolutions 2021

From Beirut and Amman to London and now Dubai, hairstylist George Massoud has seen the same mistakes made by customers all over the world. In the chair or at-home hair care, here are the resolutions he wishes his customers would make for the year ahead.

1. 'I will seek consultation from professionals'

You may know what you want, but are you sure it’s going to suit you? Haircare professionals can tell you what will work best with your skin tone, hair texture and lifestyle.

2. 'I will tell my hairdresser when I’m not happy'

Massoud says it’s better to offer constructive criticism to work on in the future. Your hairdresser will learn, and you may discover how to communicate exactly what you want more effectively the next time.

3. ‘I will treat my hair better out of the chair’

Damage control is a big part of most hairstylists’ work right now, but it can be avoided. Steer clear of over-colouring at home, try and pursue one hair brand at a time and never, ever use a straightener on still drying hair, pleads Massoud.

Types of bank fraud

1) Phishing

Fraudsters send an unsolicited email that appears to be from a financial institution or online retailer. The hoax email requests that you provide sensitive information, often by clicking on to a link leading to a fake website.

2) Smishing

The SMS equivalent of phishing. Fraudsters falsify the telephone number through “text spoofing,” so that it appears to be a genuine text from the bank.

3) Vishing

The telephone equivalent of phishing and smishing. Fraudsters may pose as bank staff, police or government officials. They may persuade the consumer to transfer money or divulge personal information.

4) SIM swap

Fraudsters duplicate the SIM of your mobile number without your knowledge or authorisation, allowing them to conduct financial transactions with your bank.

5) Identity theft

Someone illegally obtains your confidential information, through various ways, such as theft of your wallet, bank and utility bill statements, computer intrusion and social networks.

6) Prize scams

Fraudsters claiming to be authorised representatives from well-known organisations (such as Etisalat, du, Dubai Shopping Festival, Expo2020, Lulu Hypermarket etc) contact victims to tell them they have won a cash prize and request them to share confidential banking details to transfer the prize money.

The design

The protective shell is covered in solar panels to make use of light and produce energy. This will drastically reduce energy loss.

More than 80 per cent of the energy consumed by the French pavilion will be produced by the sun.

The architecture will control light sources to provide a highly insulated and airtight building.

The forecourt is protected from the sun and the plants will refresh the inner spaces.

A micro water treatment plant will recycle used water to supply the irrigation for the plants and to flush the toilets. This will reduce the pavilion’s need for fresh water by 30 per cent.

Energy-saving equipment will be used for all lighting and projections.

Beyond its use for the expo, the pavilion will be easy to dismantle and reuse the material.

Some elements of the metal frame can be prefabricated in a factory.

 From architects to sound technicians and construction companies, a group of experts from 10 companies have created the pavilion.

Work will begin in May; the first stone will be laid in Dubai in the second quarter of 2019. 

Construction of the pavilion will take 17 months from May 2019 to September 2020.

What is graphene?

Graphene is a single layer of carbon atoms arranged like honeycomb.

It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.

Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.

By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.

At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.

It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.

But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.

In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.
