Tree from dinosaur age bears fruit for first time

Tree from dinosaur age bears fruit for first time

Telegraph25-04-2025
One of the world's rarest trees is bearing fruit for the first time in a garden in Worcestershire.
A retired couple in Wichenford, Malvern, are hoping their Wollemi pine can be propagated to help the endangered species.
Dubbed 'dinosaur trees', the species dates back more than 90 million years and was thought to have died out with the T-Rex.
But a cluster of the prehistoric conifers was discovered in 1994, in a remote valley 125 miles west of Sydney, Australia.
In 2010, saplings and cuttings of the Wollemi pine were sold around the world, and one was replanted by Pamela and Alistair Thompson.
They planted it in their garden in Wichenford and discovered it bearing fruit for the first time this month.
Pamela, a 75-year-old retired police officer, said: 'It would be amazing, absolutely amazing, to have seedlings and to propagate from the world's rarest tree.
'I couldn't imagine being so lucky to do it.
'I saw a small tree for sale for more than £1,000, which shows just how rare they are.'
Pamela and her husband Alistair, a 75-year-old retired spinal surgeon, are opening their garden to the public as part of the National Garden Scheme on May 4.
The grandmother of three said: 'The long pendulous fruits are actually the male cones and the globular spiky fruits are the female cones.
'So, what we're really hoping later in the year would be to collect and germinate some of the seeds from it.
'That would be really something, but we will just have to wait and see.'
The Wollemi pine, which flourished about 200 million years ago, is thought to be the first endangered tree to be protected through mass commercial cultivation.
The tree is related to monkey puzzle trees and bears both male and female fruit.
It became the most significant botanical discovery of the 20th century when a cluster was found by a parks ranger as he abseiled into a remote canyon in the Blue Mountains of New South Wales, in 1994.
After a decade of secret survival trials, it made its first European appearance in 2005, at the Royal Botanic Gardens, Kew.
Sir David Attenborough, who planted the tree, said at the time: 'How exciting that we should discover this rare survivor from such an ancient past. It is romantic that something has survived 200 million years unchanged.'

Health Rounds: Artificial sweetener consumption linked to less effective cancer treatment

Aug 1 (Reuters) - (This is an excerpt of the Health Rounds newsletter, where we present latest medical studies on Tuesdays and Thursdays. To receive the full newsletter in your inbox for free sign up here.) In patients with melanoma or non-small cell lung cancer, consuming high levels of the artificial sweetener sucralose contributes to diminished responses to immunotherapy and poorer survival, researchers reported in Cancer Discovery, opens new tab. When the researchers had 132 patients with advanced melanoma or non-small cell lung cancer answer detailed diet history questionnaires, they found that high consumption of sucralose was linked with lower effectiveness of immunotherapies across a range of cancer types, stages and treatment methods. In experiments with mice, the researchers found that sucralose shifts the composition of microbes in the intestines, increasing bacterial species that degrade arginine, an amino acid that is essential for key immune cells called T cells. 'When arginine levels were depleted due to sucralose-driven shifts in the microbiome, T cells couldn't function properly,' study leader Abby Overacre of the University of Pittsburgh said in a statement. 'As a result, immunotherapy wasn't as effective in mice that were fed sucralose.' Laying the groundwork for a solution to the problem, the same researchers also found in the mice that supplements that boosted levels of arginine mitigated the negative effects of sucralose on immunotherapy, an approach they now hope to test in humans. 'It's easy to say, 'Stop drinking diet soda,' but when patients are being treated for cancer, they are already dealing with enough, so asking them to drastically alter their diet may not be realistic,' Overacre said. 'That's why it's so exciting that arginine supplementation could be a simple approach to counteract the negative effects of sucralose on immunotherapy.' LOW-GRADE IS NOT THE SAME AS LOW-RISK IN PROSTATE CANCER A low-grade prostate tumor is not necessarily low-risk, new research suggests. Biopsy results showing low-grade prostate cancers can sometimes lead to underestimation of disease risk and omission of surgery or radiation in patients who might benefit from such treatments, researchers warned in JAMA Oncology, opens new tab. Among roughly 117,000 men in their study with prostate biopsy results indicating a Grade Group 1, or GG1, tumor – the slowest-growing kind - one in six had intermediate- or high-risk cancer when other factors such as prostate-specific antigen levels in the blood and tumor sizes were also considered, according to the report. Such higher risk cancers are often treated with radiation therapy or removal of the prostate, the researchers noted. 'We don't want to miss aggressive cancers that initially present as Grade Group 1 on biopsy,' study coauthor Dr. Bashir Al Hussein of Weill Cornell Medicine said in a statement. 'Such underestimation of risk could lead to undertreatment and poor outcomes.' Current guidelines that advise regular monitoring – rather than treatment – for men with low-grade prostate tumors were based on studies that examined entire prostate glands after removal from patients. Biopsies test only small areas of the prostate, so they can miss more advanced or aggressive cancer cells, providing an incomplete picture, the researchers said. Some cancer experts have been suggesting recently that GG1 tumors are so slow-growing that they shouldn't even be considered malignant. The new study results could help inform those discussions, the researchers said. 'There is a misunderstanding that low grade and low risk are the same," study coauthor Dr. Jonathan Shoag of Case Western Reserve University said in a statement. "Here, we show clearly that they are not.' (To receive the full newsletter in your inbox for free sign up here)

Is acid rain is back on our 2025 apocalypse bingo card?

You remember acid rain, right? Acid rain, like holes in the ozone layer, was a phrase that almost everyone knew from the 1970s to the 2000s. People had images of taking out their umbrellas only to see the fabric melt away and their clothes not long after – not something you want to sing in. While it wasn't quite that, acid rain makes wetlands more acidic, which is lethal to some fish; leaches nutrients from the soil, killing plants and gnaws at stone buildings and sculptures. Humanity got a rare environmental win when, after decades of work (and convincing) by scientists, European and North American officials acted to curb emissions and mostly put a stop to acid rain. But acid rain is back (kind of), an expert told Metro, after a chemical has shown up in lakes, rivers, bottled water, beer and even human urine. The precipitation is caused by fossil-fuel-burning power plants and vehicles pumping out sulphur dioxide and oxides of nitrogen. The pollution mingles with water vapour up in the clouds to create toxic, corrosive acid. Acid rain can happen far away from sources of emissions as the wind blows away the gases – acid rain in Japan has been traced back to China. Scientists have observed over the last few decades that, whenever it rains, the human-made chemical trifluoroacetic acid (TFA) falls with it. TFA has been found in Canadian ice, Danish groundwater, British rivers and even Austrian cereal, with Germany seeing a fivefold increase in TFA levels in rain since the 1990s. TFA is used to make blowing agents, like the foam and plastic in packaging materials, as well as pesticides and pharmaceuticals. But environmental experts like Rowan Stanforth know it as a 'forever chemical', or a PFAS, because it takes hundreds of years to break down. 'Scientists now believe that TFA is the most abundant PFAS pollutant in the world thanks to widespread use and environmental pollution of PFAS,' Stanforth, a project officer at the antipollution charity, Fidra, told Metro. TFA is a tiny, wily and agile chemical, easily able to enter waterways and swim around them after being coughed out from industrial discharges. In June, Firda worked with researchers from the University of York to analyse 32 UK rivers for TFA – just one was not contaminated. The chemical sneaks into rain through the gases used in air-conditioner units, refrigerators and insulation foam, said Stanforth. 'The prevalence of TFA in rainfall is a worrying illustration of how far this PFAS can spread and the global problem we are facing,' Stanforth added. So, there's a lot of TFA around us right now, apparently. Should we be worried? Like with other PFAS, how much of a risk, if any, TFA is unclear. Scientists have been debating for decades about how harmful the tiny molecule is, with some saying it's about as 'toxic as table salt'. While German scientists say that TFA is toxic for reproduction and harmful to the environment, calling on EU officials to label it a toxin. European scientists wrote in a paper last year that what worries them isn't so much what we do know, it's what we don't know, especially as TFA concentrations continue to rise. The increase could pose a threat to 'planetary boundaries', natural processes that must be kept in balance to keep Earth habitable, causing 'potential irreversible disruptive impacts'. 'The troubling reality is that we are still learning about the possible effects of TFA on people and wildlife – after we're already being exposed to it daily,' said Stanforth. 'The current levels of TFA pollution in the environment are unprecedented for any PFAS. 'We do not know the impact of long-term and consistent exposure to these chemicals on human or environmental health, but we do know that these chemicals are persistent and rapidly building in our environment.' There aren't any rules or regulations in place to identify and reduce the concentrations of TFA in the environment or water supplies in the UK. The Drinking Water Inspectorate, which monitors drinking water quality, has commissioned research into the TFA in our taps. Environmental and health and safety officials are involved in the programme. But Stanforth added that there's no easy way to remove TFA from the environment – you can't just run the water through a sieve. More Trending 'We must stop the introduction of these harmful chemicals at the source,' he said. 'Every day of delay locks in decades of pollution and environmental harm.' The Department for Environment, Food and Rural Affairs said in a statement to Metro: 'Drinking water must not contain any substance at a level which would constitute a potential danger to human health. If Trifluoroacetic acid were detected in drinking water, companies should take action in the same way as for other PFAS compounds. 'We continue to work closely across government and with regulators and the devolved administrations to assess levels of so-called forever chemicals occurring in the environment, their sources, and potential risks.'

Highland juniper forest given special European status

A Highland forest has become the first in the UK to receive special European protection for its unique genetic diversity. The native juniper and silver birch woodlands at Trees for Life's Dundreggan rewilding estate near Loch Ness have been designated as official Gene Conservation Units. The European status is only given to long-standing, naturally occurring tree populations that show distinct local adaptation. It's a UK-first for any juniper forest and recognises the 10,000-acre site in Glenmoriston as internationally significant for conserving genetic diversity in native species. The designation forms part of a continent-wide network overseen in the UK by Forest Research, aiming to safeguard the genetic resilience of key tree populations against threats such as climate change, pests and disease. Gwen Raes, Dundreggan estate manager, said: 'This designation underlines why letting our ancient woodlands grow back naturally is so important to us at Dundreggan, and it celebrates the remarkable remnants of naturally occurring and locally adapted juniper and silver birch that still survive on the estate. 'Through this designation and further management, we aim to ensure these unique woodlands secure the extra care and attention they need, so they are protected and enhanced going forward.' The unusually high rainfall at Dundreggan – rare for juniper habitats – and its position at the western edge of silver birch's natural range have contributed to the genetic uniqueness of these trees. Forest Research scientists believe the species at the site have evolved over generations, making them valuable on both UK and European levels. Tom Sim, the scientist responsible for registering the UK's Gene Conservation Units, said the trees' natural origins and adaptation make them genetically distinct. 'They have likely adapted to their local conditions over many generations,' he said. 'As a result, we would expect the stands to be representative of distinct genetic variation for each species at a UK and European level.' The estate employs a 'dynamic conservation' approach, encouraging natural regeneration to help the trees continue adapting. The designation means ongoing monitoring to protect and enhance their long-term survival. Juniper, more common in drier eastern parts of Scotland, supports a wide variety of wildlife and plays a role in gin production. Silver birch, fast-growing and nutrient-rich, supports over 300 insect species and contributes to healthy soils. The Dundreggan Rewilding Centre offers visitors access to the woodlands via a range of forest trails, including the accessible Juniper Path. The lower part of the estate is home to around 50,000 juniper and 80,000 silver birch trees. Trees for Life says the designation is a milestone in its mission to restore Scotland's wild forests for nature, people, and climate.
