Super glue can be squirted onto internal wounds to treat patients in war zones or those involved in car accidents

Treating serious wounds following car accidents or in war zones could be made a lot easier thanks to a potentially life-saving surgical glue that can seal wounds within seconds.

MeTro, which has been developed by biomedical engineers from the University of Sydney and Northeastern University, can be squirted onto patients’ wounds, and works on areas that continually expand and relax – such as lungs, hearts and arteries – as well as on internal wounds that are often in hard-to-reach areas.

The glue sets in 60 seconds once treated with UV light, and the technology has a built-in degrading enzyme, which can be modified so that the sealant lasts anywhere from hours to months.

“The beauty of the MeTro formulation is that, as soon as it comes in contact with tissue surfaces, it solidifies into a gel-like phase without running away,” said assistant professor Nasim Annabi of Northeastern University.

“The potential applications are powerful – from treating serious internal wounds at emergency sites such as following car accidents and in war zones, as well as improving hospital surgeries,” added Professor Anthony Weiss from the University of Sydney.

So far, MeTro has quickly and successfully sealed incisions in the arteries and lungs of rodents and the lungs of pigs, without the need for sutures and staples.

The next step for the sealant is to begin clinical trials.

“MeTro seems to remain stable over the period that wounds need to heal in demanding mechanical conditions and later it degrades without any signs of toxicity; it checks off all the boxes of a highly versatile and efficient surgical sealant with potential also beyond pulmonary and vascular suture and staple-less applications,” said professor Ali Khademhosseini, who is the director of the Biomaterials Innovation Research Center at Harvard Medical School.

“We have shown MeTro works in a range of different settings and solves problems other available sealants can’t. We’re now ready to transfer our research into testing on people. I hope MeTro will soon be used in the clinic, saving human lives,” added Weiss.

The process by which MeTro works has been said to resemble the silicone sealants used around bathroom and kitchen tiles.

“When you watch MeTro, you can see it act like a liquid, filling the gaps and conforming to the shape of the wound,” said Weiss.

“It responds well biologically, and interfaces closely with human tissue to promote healing. The gel is easily stored and can be squirted directly onto a wound or cavity.”

Researchers believe modified CRISPR could be used without editing DNA

Researchers from the US' Salk Institute have used CRISPR as a switch that turns genes on and off and allows harmful mutant genes to be disabled without affecting the structure of their DNA. Until this development gene editing using CRISPR carried the risk of causing unintended effects.

San Francisco votes to restrict delivery robots

San Francisco officials have voted to restrict where delivery robots can go in the city, amid concerns about the safety of pedestrians, particularly elderly people and children. Start-ups will now have to get permits to use such bots, which will be restricted to less crowded urban areas.

Steam stops accepting Bitcoin

When Valve first started accepting Bitcoin in April 2016 it was trading around $450 per coin. Today, with Bitcoin surging past $12,000 per coin, Valve has announced that "Steam will no longer support Bitcoin as a payment method on our platform due to high fees and volatility in the value of Bitcoin."

The UK government is launching a fintech competition to help renters get on the property ladder

The UK government is offering £2 million to fintech developers who come up with a tool that lets renters record and share their payment data.

The Rent Recognition Challenge, which was first announced as part of the chancellors’ autumn budget, will task developers with finding a way to record payment data from Britain’s 11 million renters in a bid to improve their credit scores and ultimately help them to get a mortgage.

“Most lenders and Credit Reference Agencies are unable to take rental data into account, because they don’t have access to it.

“The Rent Recognition Challenge will challenge firms to develop an innovative solution to this problem and help to restore the dream of home ownership for a new generation,” said the economic secretary to HM Treasury, Stephen Barclay.

The competition will provide an initial round of grant funding to six promising proposals to help turn their ideas into workable products.

A panel of leading figures from the Fintech sector will then whittle the six down to just a handful of teams who will receive further funding and support to bring their ideas to market.

“People’s monthly rent is often their biggest expense, so it makes sense for it to be recognised when applying for a mortgage. Without a good credit score, getting a mortgage can be a real struggle.”

The government’s attempt to help more people out of private renting arrangements and into home ownership comes after Scottish Widows published a report that warned tomorrow’s pensioners will have to find huge amounts of money to pay ever-escalating rents to private landlords.

Scottish Widows projected one in eight retirees will be renting by 2032, which works out to three times the number renting today. It also said there is a £43bn gap between the income and savings people have now and what the rent bill will be in retirement.

Speaking to the Guardian, Dan Wilson Craw of campaign group Generation Rent said: “The common perception is that retirees either own their home outright or have a council tenancy, so the government will be in for a nasty shock as more of us retire and continue to rent from a private landlord.

“Many renters relying on pensions will qualify for housing benefit which will put greater strain on the public finances.”

The Rent Recognition Challenge will open to applications early in the New Year, and development will conclude in October 2018.
