In what is a major breakthrough thanks to new research, scientists are claiming they have found a potential cure for hair loss.
With statistics and estimations showing that approximately 85% of men and 40% of women will be affected by hair loss at some point in their lives, researchers at the University of California Riverside have been studying hair follicles in depth to try and find out as much as possible.
In a new study published in the Biophysical Journal, the team at UC Riverside explained that they decided to focus on hair follicles as they’re the only organ in humans that regenerates automatically and regularly, even if they haven’t been injured – and it’s from this research that they they discovered that just a single chemical is the key cause for hair follicle cells dividing and dying.
They discovered a type of protein named TGF-beta.
TGF-beta controls the process in which cells in hair follicles – including stem cells – divide and form new cells, or orchestrate their own death, which eventually leads to the death of the whole hair follicle.

But could this be reversed and successfully cure baldness and heal wounds? Scientists hope so.
Explaining more about the discovery in the study, UC Riverside mathematical biologist and study co-author Qixuan Wang said: “In science fiction when characters heal quickly from injuries, the idea is that stem cells allowed it.

“In real life, our new research gets us closer to understanding stem cell behaviour, so that we can control it and promote wound healing.”
“TGF-beta has two opposite roles,” Wang added.
“It helps activate some hair follicle cells to produce new life, and later, it helps orchestrate apoptosis, the process of cell death.”

While no one is entirely sure why follicles kill themselves, and some hypotheses suggest it’s a trait inherited from animals shedding fur to survive hot summer temperatures, or trying to camouflage, what we do know is that with TGF-beta, as is the same with many chemicals, it’s the amount that makes the difference, and if the cell produces a certain quantity of TGF-beta, then it activates cell division.
Wang continued: “Even when a hair follicle kills itself, it never kills its stem cell reservoir [as] when the surviving stem cells receive the signal to regenerate, they divide, make new cell and develop into a new follicle.”
Of course, there’s still some way to go until baldness is cured – however, researchers have suggested that it may be possible to activate follicle stem cells and stimulate hair growth if more research is carried out on how TGF-beta communicates with other genes and promotes cell division.
If they can find a way to accurately control levels of the protein, then it could lead to an effective treatment for hair loss.

“Potentially, our work could offer something to help people suffering from a variety of problems,” Wang concluded.
Two North West cities named among the ‘noisiest’ in the UK – including Manchester

A new analysis has revealed a list of the noisiest cities in the UK, and two Greater Manchester locations are in the top five.
From blaring sirens and car horns, to house parties, barking dogs, and loud neighbours, escaping the noise of a city can feel almost impossible – even in your own home.
No matter whether you live in the hustle and bustle, or you’re out in the sleepier suburbs, noise can keep you up at night, disturb your peace, and lead to frustration. But just how loud are Greater Manchester’s cities compared to the rest of the UK? In a bid to get to the bottom of it, Alpine Hearing Protection has done some research to compile a top 10 list.
And both Salford and Manchester have found themselves not just within the top 10, but within the top five… and to make matters worse, Salford has actually claimed the number one spot.
The reason Salford has found itself at the top of the list, according to the research, is because it sits at the intersection of several major transport and urban hubs, with major motorways running through or around the city including the M60, M61, and M62.
Major rail routes also run through the city – including via Salford Crescent – which sees 16 million passengers every year, and also leads to Manchester Airport.

Parts of Salford are also very built-up, making pockets of the city noisy – especially in the concentrated centre where traffic, construction, nightlife and commercial activity get loud.
And of course, like any growing city, construction noises have been noted as ‘particularly bothersome’ for residents where major developments are springing up.
Manchester is third on the list of noisiest cities, due to many of the same reasons as Salford.
But the difference being that Mancunians are noted as one of the many reasons why the city is so loud – with residents making 5,301 noise complaints across Manchester between January 2024 and January 2025, and Hulme identified the loudest area with 304 complaints.
As well all know, Manchester is also home to many universities, which brings an active nightlife scene to the region, especially in the city centre, and in recent FOI data, it was revealed that the University of Manchester saw 2,049 noise complaints in the last five years.
Motorists warned of common winter driving habit that could land them with annoying fines

With the temperatures drastically dropping now as we head into winter, motorists are being warned against a common driving habit.
On a wintry morning when the windscreens are frozen and your hands are equally as frozen too, it’s pretty common for drivers to start the engine, turn the heater right up, and remain stationary for several minutes to warm the car up before setting off on their journey… but did you know that doing this could see you, inadvertently, fall foul of the law?
That’s right – as ridiculous as it sounds, leaving your car engine running ‘unnecessarily’ while parked on a public road is illegal.
And to make matters worse, the rules on ‘engine idling’, as it’s known, apply regardless of whether the driver is using the heating, waiting for someone, or simply sitting in the vehicle.
Known as a stationary idling offence, Rule 123 of the Highway Code states that drivers must not leave a vehicle’s engine running unnecessarily while it is stationary on a public road, and according to the rule, a fixed penalty of up to £80 can be issued, right there and then.

Fines will only be handed out if a motorist is stopped by a police officer who asks them to switch the engine off, and they fail to comply.
“However tempting it might be to sit in a vehicle with the engine running and the heater on to warm up, we strongly advice against it,” commented RAC senior policy officer Rod Dennis.
“As well as polluting the air and wasting fuel, drivers who leave their engines idling unnecessarily on a public road also risk an on-the-spot fine of £80. On cold mornings, the best approach is to clear any ice or snow properly and ensure windows are fully de-misted before setting off, then get on your way and let the car warm you up.”
There are some exceptions to the rule, however, as keeping the engine running is permitted in certain circumstances.
This includes when a vehicle is stationary because of traffic conditions, when the engine needs to run so a mechanical fault can be investigated, or if certain work is being carried out on the side of the road.
