Researcher wins grant for tissue ageing study

A university researcher has received a grant of up to US$150,000 to study how bone fractures may accelerate tissue ageing and test potential treatments.
Dr Madison Doolittle, assistant professor in the Center for Regenerative Medicine and Skeletal Development at the UConn School of Dental Medicine, recently received the funding from the American Federation for Aging and Research (AFAR).
AFAR’s Grants for Junior Faculty Program provides up to US$150,000 to junior faculty for one to two years to conduct research that will form the basis for longer-term work on the biology of ageing.
“I am thrilled to receive this award from AFAR,” said Doolittle. “At a time where research funding is in such jeopardy, I am incredibly thankful to AFAR for providing this award so that we can continue to study the complicated nature of biological ageing in the skeleton.”
The funding will allow Doolittle’s lab to study injury as a catalyst for accelerated skeletal tissue ageing. After breaking a bone, lingering symptoms such as pain, stiffness and arthritis can occur, and this can increasingly worsen with age.
Clinical data show that a previous bone fracture, regardless of age, can increase the risk of fracture in old age. Based on these factors, it is believed that previously fractured bones age faster than non-fractured bones, resulting in accelerated bone loss driven by higher proportions of aged “senescent” cells.
Senescent cells are cells that have stopped dividing but remain in the body, releasing substances that can damage surrounding tissue and speed up ageing processes.
This award will allow Doolittle to study this phenomenon in mouse models and test a potential therapeutic approach to correct premature ageing in both bone and systemic tissues.
“What I’m most looking forward to is the effect these findings may have on eventual clinical applications, as fractures in the elderly are one of the most catastrophic events regarding frailty and loss of independence,” said Doolittle. “In future projects, it would be interesting to see if this occurs in other tissues as well, which would implicate injury as a universal driver of premature ageing.”
The goal of the Grants for Junior Faculty Program is to assist in the development of the careers of early-career investigators committed to pursuing careers in ageing research.
“A core grant programme since AFAR’s inception, the AFAR Grant for Junior Faculty provides flexible support at a critical juncture in an early career investigator’s career when research funding is most difficult to secure,” notes Stephanie Lederman, executive director of AFAR. “This grant has helped many promising scientists advance the field’s understanding the basic mechanisms of ageing, building a foundation of knowledge that will help us all live healthier, longer.”

One in 20 children has high blood pressure, study finds

Rates of high blood pressure in children have almost doubled since 2000, with more than one in 20 now affected, new global research shows.
In 2020, 6.2 per cent of under-19s had high blood pressure, compared with 3.2 per cent in 2000.
High blood pressure, also known as hypertension, now affects 114 million children worldwide, according to an international team including academics from the University of Edinburgh and Zhejiang University in China.
The authors examined data on 443,000 children from 21 countries and found obesity was a substantial driver of the problem.
Nearly 19 per cent of children and adolescents with obesity have high blood pressure, compared with 3 per cent among those with a healthy weight.
In England, one in ten (10.5 per cent) children in the first year of primary school is obese. By the final year, 22.2 per cent are obese, according to the National Child Measurement Programme.
High blood pressure occurs when the force of blood pushing against artery walls is consistently too high, which can damage blood vessels and organs over time.
Co-author Dr Peige Song of Zhejiang University attributed higher rates to unhealthy diets, decreased physical activity and rising childhood obesity.
She said: “The analysis showed that children and adolescents with obesity are nearly eight times more likely to develop hypertension.”
“Parents play a pivotal role in preventing and managing high blood pressure in children.
“Promoting healthy habits, such as a balanced diet rich in fruits, vegetables and whole grains while minimising salt and sugar intake, can substantially reduce the risk of hypertension.”

US$100m UK tech entrepreneurs shift focus from real estate to longevity

Whilst running a US$100m-a-year technology business Paul Statham and his team turned their attention to longevity.
Speaking to Agetech World the London-based entrepreneur took up the story: “ I travel extensively and the only way I could keep in touch with my late mother Kathy, who was suffering from dementia, was through the telephone.
“But an hour’s phone call is not the same for someone who wants people around her more of the time, that resonated with me and so we decided to look at the problem and find a solution.”
This led to the foundation of the home-based technology smart speaker Sentai, which provides domestic companionship and assistance for those of advancing years.
Back in 2021 the Sentai team secured £172,568 from quango Innovate UK and Statham and his team have since invested ‘several million pounds’ of their own money bringing Sentai to fruition.
What is Sentai?
Statham elaborated: “Sentai is a smart speaker which uses AI to communicate and support older adults in their daily tasks. It acts as a digital companion as well as a digital assistant.

Paul Statham
“In the assistant space it will provide daily reminders of tasks and appointments, and from the companion perspective, it will engage in conversation.
“The AI technology available now is truly phenomenal; unbelievably clever. It is able to get to know the person it is talking to and truly does become part of their world.
“Sentai is there to support and help people; it doesn’t take over their lives but works as part of their life. It gets to know people and can play games, deliver medical reminders, or, for example, assist with reminder prompts on things such as ensuring their drinking enough water or getting enough exercise.
“As we age, we need more care, but many elderly people are becoming isolated and spending less time with their families, so we came up with the idea of using this technology to help provide additional support.”
What is the potential of Sentai?
Trials of the first Sentai began over the summer with the company looking to launch in January 2026.
It has a number of primary target markets in its sights with the potential to save taxpayers and home care organisations many millions of pounds.
Statham continued: “There’s the retail/consumer market. We’re selling Sentai through the internet, and other primary marketing channels.
“Then there’s the domiciliary care market; companies and organisations who provide home care for people.
“Sentai is a great help to these organisations and they are potentially prime users of the product as it allows them to provide additional hours of coverage with slimmed-down costs.
“In the UK it’s difficult to find domestic care workers, there are not enough as it is, and demand is set to increase. So the domiciliary care market is a massive opportunity and we are really leaning into this.”
Sentai is working with a number of local authorities delivering home care and it is also currently involved in a trial with an NHS Trust in South East which permits two-way communications between a patient and the hospital.
“When patients leave hospital, if they’ve not got a loved one or a family member to stay with them, then they will take a Sentai home. This will allow the hospital to assess their progress and make sure their needs are being met.
“We’ve got various councils piloting Sentai for assisted living in trials which allow the care providers to monitor a patient’s needs with the view of developing Sentai as a concierge service.”
While some trial users have been found to use Sentai more than expected others have been less verbose, and, so, over time the AI speaker is able to familiarise itself with its user’s personalities and deliver ‘concise’ or ‘chatty’ modes depending on individual preferences.
At £29.50 (US’$39) per month, or £294 (US$387) annually for use of the speaker and app, Sentai’s pricing makes the technology relatively accessible.

Keeping families connected
Statham and his team founded their previous company Condeco Software twenty years ago.
It had developed into a leading global player in workspace management and resource scheduling, effectively ensuring the real estate footprint of a company matched its needs.
As the pandemic shifted workspace requirements Condeco’s software made it one of the leading players in its field.
By late 2022, as the company’s annual revenues topped US$100m, it was sold in a private equity deal for an undisclosed sum, with some of this money now being ploughed into Sentai.
Statham added: “We launched our product because we were thinking of our own loved ones and how we wanted to stay in contact with them.
“That is the DNA of the business. We want to keep families connected and keep older adults relevant and help them live independently for longer.
“If we can help with loneliness and companionship, and help connect families to their loved ones, then that will be an unbelievable success.”
