Scientists have pinpointed 145 potential “height genes” in cells that make up the cartilage at the ends of children’s bones and affect how tall they grow.

These cartilage cells, known as chondrocytes, multiply and mature in areas of tissue called growth plates, which sit near the ends of long bones in children and teens and determine each bone’s future length and shape. When a person’s growth is complete, these cartilaginous growth plates “close” and are replaced by hard bone. Scientists already knew that chondrocytes play a role in bone growth and human height, but narrowing down which genes control the cells’ growth — and, thus, our statures — has proved difficult.

“Pinpointing specific genes associated with human height is a challenging task, as height is a complex trait that is influenced by both genetic and environmental factors,” Dr. Nora Renthal (opens in new tab) , a pediatric endocrinologist at Boston Children’s Hospital and Harvard Medical School and senior of the new study, told Live Science in an email. “Our study focused on cartilage cells specifically because they are the primary cell type involved in bone growth.”

In a study published Friday (April 14) in the journal Cell Genomics (opens in new tab) , Renthal and her colleagues screened 600 million mouse cartilage cells to find genes that influence how the cells proliferate and mature. They used CRISPR genome-editing technology to “knock out” candidate genes, which allowed the researchers to observe what happened when these genes were erased and no longer regulated cartilage cells.

The researchers found 145 genes that, when knocked out, triggered abnormal growth and development of mouse cartilage cells. These patterns of abnormal growth were similar to those seen in certain skeletal disorders, such as skeletal dysplasia — a group of genetic disorders that affect the development of bones, joints and cartilage in babies. Those with skeletal dysplasia are typically of short stature and have short limbs, among other symptoms.

Next, the researchers compared these 145 mouse genes with previous results from large-scale genetic studies of human height, called genome-wide association studies (GWAS). In those studies, researchers compared the DNA of thousands of people of different heights to look for gene variants associated with height, Renthal explained. To control for non-genetic factors that influence the trait under study, such as nutrition and disease in the case of human height, these factors are incorporated into GWAS, according to a 2021 review published in the journal Nature Reviews Methods Primers (opens in new tab) .

“These studies have contributed to our understanding of the genetic basis of complex traits like height by identifying specific genetic regions and genes that are associated with the trait,” Renthal said.

The comparison revealed a remarkable overlap between genetic “hotpots” linked to human height in the GWAS and the 145 genes that control cartilage cell growth in mice. This means that these genes, which the researchers have now precisely located in the human genome, could influence height more than other genetic factors do.RELATED STORIES—More than 150 ‘made-from-scratch’ genes are in the human genome. 2 are totally unique to us.

“Our current study has helped to identify new genes potentially involved in bone growth and development,” Renthal said. “Specific genes and pathways involved in the maturation and proliferation of chondrocytes, the cells that make up cartilage in our bones, play a critical role in human height.”

Results from mouse cells may not mirror cellular processes in humans, Renthal noted in a statement (opens in new tab) , but the researchers think height genes could come in handy in clinical settings. 

“It is our hope that the identification of these 145 genes will help patients with skeletal dysplasia and other skeletal disorders,” Renthal told Live Science.

Energy bills to rise again from January but spring falls to come, research firm Cornwall Insight forecasts

Energy bills are to rise again next year, according to a respected forecaster.

Costs from January to March are projected to rise another 1% to £1,736 a year for the average user, according to research firm Cornwall Insight.

The energy price cap, which sets a limit on how much companies can charge per unit of electricity, is also expected to rise, costing typical households an extra £19 a year.

It’s a further increase after energy costs rose 10% from October.

After the latest hike, there were hopes of a fall in the new year, but volatile wholesale gas and electricity markets are still above historic average costs.

Every three months energy regulator Ofgem revises the cap based on wholesale costs.

The official January price cap announcement will be made on Friday.

It comes as millions of pensioners lost their automatic winter fuel allowance payment after the government means-tested the benefit.

Meanwhile, Cornwall Insight’s principal consultant Dr Craig Lowrey warned “millions” of households won’t heat their homes to “recommended temperatures, risking serious health consequences” with bills on the rise.

“With it being widely accepted that high prices are here to stay, we need to see action,” he said, suggesting options like cheaper rates for low-income homes, benefit restructuring, or other targeted support for the vulnerable “must be seriously considered”.

The energy price cap system is being reviewed by Ofgem with possible changes to the standing charge coming over the next year.

Masked burglars 'raid' Windsor Castle grounds 'while William, Kate and children slept at home on estate'

Masked burglars have stolen farm vehicles from the Windsor Castle estate while members of the Royal Family are believed to have been asleep nearby.

Two men scaled a 6ft fence on the night of 13 October and used a stolen truck to break through a security gate, The Sun first reported.

The pair then fled with a pick-up and a quad bike that were stored in a barn.

The King and Queen were not in residence.

But the Prince and Princess of Wales, along with their three children George, 11, Charlotte, nine, and six-year-old Louis were believed to have been in their home, Adelaide Cottage, on the estate, according to The Sun.

The family moved there in 2022.

In a statement, Thames Valley Police said: “At around 11.45pm on Sunday 13 October, we received a report of burglary at a property on Crown Estate land near to the A308 in Windsor.

“Offenders entered a farm building and made off with a black Isuzu pick-up and a red quad bike. They then made off towards the Old Windsor/Datchet area.

“No arrests have been made at this stage and an investigation is ongoing.”

UK told to expect 'disruptive snow' as warnings cover large parts of country

The UK is braced for “disruptive snow” as yellow weather warnings cover large parts of the country until Tuesday – with the Met Office saying there is the “potential” for the alerts to be “escalated”.

The forecaster has warned up to 20cm of snow may accumulate in the worst affected areas as the country experiences its “first taste of winter”.

The Met Office has also told people to expect ice, cold temperatures and wintry showers this week.

A yellow warning for snow and ice is in place for much of the north of the country – covering areas in the East Midlands, Yorkshire, Wales and the north of England – from 7pm on Monday night to 10am on Tuesday morning.

Those in the impacted areas have been told power cuts are possible and mobile phone coverage might be affected.

The Met Office has said there is a “slight chance” some rural communities could be cut off and that bus and train services may be delayed or cancelled.

People are also warned to be careful not to slip or fall on icy surfaces.

The Met Office has said there will be bright spells across northern and eastern areas throughout today, but rain in the south and west will gradually spread northeastwards and turn to snow over northern hills.

Tom Morgan, Met Office meteorologist, said: “We could see some disruptive snow in the Pennine regions, in particular, the Peak District as well, especially Monday night, but we could well see some impacts lasting on until Tuesday morning’s rush hour.

“Even down to lower levels, we could well see some snow as well, so quite a bit of disruption possible by Tuesday morning, and then the week ahead is likely to stay cold nationwide, a windy day on Tuesday, and then winter showers through the week ahead.”

Mr Morgan said that despite a “mild” start to the month, the cold conditions are more typical of “mid-winter to late-winter”.

“What we can say is that it’s going to be very cold for the time of year, there will be widespread overnight frosts, and a few locations where there’s snow on the ground,” he continued.

Meanwhile, a yellow snow and ice weather warning that came into force at 4pm on Sunday will end at 11am this morning.

The warning covers the northern tip of Scotland and people there have been told there may be icy patches on some untreated roads, pavements and cycle paths.

The Met Office has said there is “potential” for both yellow warnings to be “escalated”.

In southern England, a typical maximum temperature for this time of year is 11C (52F), but daytime highs for the week ahead are forecast to be around 5C (41F), while some parts of Scotland will reach “only just above freezing”, Mr Morgan said.

The meteorologist said the public can best prepare for the wintry weather by checking their cars are suitable for icy and potentially snowy conditions and to take extra supplies including food, blankets and a fully charged mobile phone with them on journeys.

He added there were “likely” to be changes to the weather warnings in the coming days, and that “winter flurries” could be seen in the south of England later in the week.

Despite the cold conditions, the “whole of the UK” will enjoy more sunshine this week, the meteorologist added.

He said: “There’ll be some snow showers in the peripheries of the UK, particularly northern Scotland, and down the east and the west coast, but if you live inland and you live in the south, there’ll be lots of sparkly blue skies on the most days through Tuesday to Friday.”

It comes as a cold weather alert issued by the UK Health Security Agency, which was introduced at 9am on Sunday, will be in place until 9am on Thursday.

It covers a large area of England, north of Northhampton. The alert is triggered when there is a risk that healthcare services might face extra pressure and is designed to prepare those who are “particularly vulnerable” and “likely to struggle to cope”.
