Labour politicians warn former PM had boosted Tory and Reform climate sceptics on the eve of local elections
Tony Blair has been forced by Downing Street to row back from his criticism of the government’s net zero strategy after furious Labour politicians warned he had given a boost to Tory and Reform sceptics on the eve of the local elections.
Climate experts also accused the former prime minister of granting political cover to fossil fuel interests and weakening momentum behind the UK’s legally binding target to reach net zero emissions by 2050.

Government to press ahead with net zero plans as Keir Starmer rejects Tony Blair’s criticisms of climate policy
Almost all new homes in England will be fitted with solar panels during construction within two years, the government will announce after Keir Starmer rejected Tony Blair’s criticism of net zero policies.
Housebuilders will be legally required to install solar panels on the roofs of new properties by 2027 under the plans.

A restoration project at Sharpham near Totnes aims to tackle the loss of the natural world while helping people build mental resilience
Two landscapes separated by a wide sweep of river tell a story of change. On one side is traditional farmland, close-cropped grazing, uniform grasses, neatly tended hedges and a sparsity of trees, a farmscape ubiquitous across England. On the riverbank opposite, rougher, less uniform grasses grow unevenly between trees, thistle and brambles, in a chaos of natural disorder swaying in the breeze towards the reedbeds below.
The land on the Sharpham estate side of the River Dart used to be a mirror of the traditional farmscape on the opposite bank. It hosted a non-organic dairy farm and a vineyard, within a tightly controlled 18th-century heritage landscape of deforested parkland.

The celebrated presenter warns of ‘modern day colonialism at sea’ as he highlights the destruction caused by overfishing and bottom trawling
When David Attenborough’s Blue Planet II documentary aired eight years ago, its impact was so strong it was credited with bringing about a revolution in the way people use plastics. Now film-makers are hoping he can do the same for other destructive environmental practices that the world’s best-known living naturalist describes as “draining the life from our oceans”.
The industrial fishing method of bottom trawling is the focus of a large part of Attenborough’s latest film, Ocean, which airs in cinemas from 8 May, the naturalist’s 99th birthday. In a remarkably no-holds-barred narrative, he says these vessels tear the seabed with such force “the trails of destruction can be seen from space”. He also condemns what he calls “modern day colonialism at sea”, where huge trawlers, operating off the coasts of countries reliant on fish for food and livelihoods, are blamed for dwindling local catches.

A warming tundra has seen unexpected shifts, raising the alarm about fragile ecosystems and those who rely on them
Scientists studying Arctic plants say the ecosystems that host life in some of the most inhospitable reaches of the planet are changing in unexpected ways in an “early warning sign” for a region upended by climate change.
In four decades, 54 researchers tracked more than 2,000 plant communities across 45 sites from the Canadian high Arctic to Alaska and Scandinavia. They discovered dramatic shifts in temperatures and growing seasons produced no clear winners or losers. Some regions witnessed large increases in shrubs and grasses and declines in flowering plants – which struggle to grow under the shade created by taller plants.

Aluminium emissions from satellites as they fall to Earth and burn up is becoming more significant as their numbers soar
Right now there are more than 9,000 satellites circumnavigating overhead, keeping track of weather, facilitating communications, aiding navigation and monitoring the Earth. By 2040, there could be more than 60,000. A new study shows that the emissions from expired satellites, as they fall to Earth and burn up, will be significant in future years, with implications for ozone hole recovery and climate.
Satellites need to be replaced after about five years. Most old satellites are disposed of by reducing their altitude and letting them burn up as they fall, releasing pollution into Earth’s atmosphere such as aerosolised aluminium. To understand the impact of these growing emissions from expired satellites, researchers simulated the effects associated with an annual release of 10,000 tonnes of aluminium oxide by 2040 (the amount estimated to be released from disposal of 3,000 satellites a year, assuming a fleet of 60,000 satellites).

Guardian reporters map out how Trump is eviscerating efforts to protect the natural world – from ‘drill, baby, drill’ to mass firings
Donald Trump has never been mistaken for an environmentalist, having long called the climate crisis a “giant hoax” and repeatedly lauding the supposed virtues of fossil fuels.
But the US president’s onslaught upon the natural world in this administration’s first 100 days has surprised even those who closely charted his first term, in which he rolled back environmental rules and tore the US from the Paris climate agreement.
Taken more than 140 actions to roll back environmental rules and push for greater use of fossil fuels.
Set about rewriting regulations that limit pollution from cars, trucks and power plants.
Officially reconsidering whether greenhouse gases actually cause harm to public health.
Legally targeted states that have their own laws on tackling the climate crisis.
Speeded up environmental reviews of drilling projects, from years to just a few weeks.
Winding back water efficiency standards for showers and toilets and halting a phase-out of plastic straws

Joshua Bonnetta spent 8,760 hours recording a pine – then honed it down into a four-hour album full of creatures, cracking branches and quite possibly the sound of leaves growing
What does a landscape sound like when it’s not being listened to? This philosophical question was a catalyst for film-maker and artist Joshua Bonnetta, who has distilled a year of recordings from a single tree in upstate New York – that’s 8,760 hours – into a four-hour album, The Pines. As Robert Macfarlane writes in his accompanying essay, The Pines is a reminder of the natural world’s “sheer, miraculous busyness”, its “froth of signals and noise”. It is rich with poetic meaning, and resonant amid the climate emergency.
“It started as a personal thing,” Bonnetta explains from his studio in Munich, where he relocated from the US in 2022. For over 20 years he has made sonic records of places as private mementos, but recent experiments with long-form field recording led him to push himself “to document this place in the deepest way I could”. On a residency in the Outer Hebrides between 2017 and 2019, Bonnetta made the sound installation Brackish, a month-long continuous radio broadcast from a weather-resistant hydrophone – an underwater mic – by a loch. “I started to leave the recorder for a day or two, then it just got longer,” he says. “Amazing things happen when you’re not there to interfere … This allows you a different, very privileged window into the space.”

Poremećaj pozornosti s hiperaktivnošću (ADHD) može pogoršati anksioznost, a anksioznost može pogoršati ADHD. Djevojčice su posebno osjetljive na razvoj anksioznih poremećaja. Nova studija otkrila je nove korelacije između ADHD-a i anksioznosti te se čini da je odnos između njih drugačiji kod djevojčica i dječaka.
Tjelovježba može suzbiti štetne učinke liječenja raka, poput oštećenja srca i živaca te moždane magle, sugerira sveobuhvatan pregled postojećih studija. Čini se da tjelovježba također poboljšava psihološku dobrobit i ukupnu kvalitetu života, što daje težinu njenom rutinskom uključivanju u protokole liječenja bolesti.
Ljudi koji imaju oštećenje određenog dijela mozga skloniji su impulzivnosti, a novo istraživanje otkrilo je da to oštećenje mozga također povećava vjerojatnost da na njih utječu drugi ljudi.
Čak i male količine vježbi visokog intenziteta utječu na mozak, pokazuje nova studija. Naime, pokazalo se da trening izdržljivosti i dobra kondicija mogu smanjiti rizik od demencije i potaknuti zdravo starenje mozga.
Svakodnevna izloženost određenim kemikalijama koje se koriste za izradu plastičnih kućanskih predmeta mogla bi biti povezana s više od 356 000 smrtnih slučajeva od srčanih bolesti u svijetu koji su se dogodili samo u 2018. godini, pokazuje nova analiza.
Američko istraživanje pokazalo je, da osobe s rakom debelog crijeva i dokumentiranom poviješću visoke konzumacije kanabisa imaju više od 20 puta veću vjerojatnost da će umrijeti unutar pet godina od dijagnoze u usporedbi s onima bez takve povijesti.
Rezultati nove studije pokazali su da je brže biološko starenje povezano s porastom razine feritina. Ovo opažanje ukazuje na to da visoke razine željeza potiču oksidativni stres, čime ubrzavaju biološko starenje.
Nova studija ukazuje da se rak prostate može dijagnosticirati u ranoj fazi bolesti pomoću jednostavnog uzorka urina. Naime, znanstvenici su, uz pomoć umjetne inteligencije i opsežnih analiza genske aktivnosti u tumorima, identificirali nove biomarkere visoke dijagnostičke preciznosti.
Formiranje, pohranjivanje i pronalaženje pamćenja temeljni su procesi koji definiraju tko smo i kako komuniciramo sa svijetom. Na staničnoj razini, ovi se procesi oslanjaju na specijalizirane neurone zvane engramske stanice - neuronske populacije koje fizički kodiraju naša iskustva i omogućuju nam da ih se kasnije prisjetimo.
Švedski znanstvenici otkrili su jedinstvenu sposobnost posebnog podtipa prirodnih stanica ubojica u imunološkom sustavu, nazvanih adaptivne NK stanice, da pamte tumore jajnika i učinkovito ih napadaju. Ovo otkriće, moglo bi utrti put novim, snažnijim imunoterapijama za teško liječive karcinome.
