Her research popularised the idea of the wood wide web, but the scientific backlash was brutal. As the author of The Mother Tree returns to the forest in a new book, she discusses her battle to reimagine our relationship with nature
In 2018, the ecologist and writer Suzanne Simard was conducting research in the forested Caribou Mountains of western Canada when a thunderstorm rolled in. She was with her two teenage daughters and her close friend and colleague, Jean Roach. They saw flashes of lightning, heard a loud rumble and then they smelled smoke. They were forced to run the half kilometre back to Simard’s truck as the trees behind them caught alight and the air grew thick. As they ran, animals burst out of the forest: a deer, a rabbit, a grey wolf. They reached the truck with no time to spare, all four of them covered in soot and dirt. Overhead, helicopters began circling the orange-black air, dropping water on the flames below.
Wildfires have become an ever bigger problem in Canada. The 2018 wildfires were the biggest in British Columbia’s history, but this record was broken in 2021, and then again in 2023, when fires consumed an area three times the size of the Canadian province of Nova Scotia and the smoke travelled as far as New York City. The cause is not only global heating, which has brought hotter, dryer summers, but also the changing makeup of the forest. When logging companies clear forest, they replant it with fast-growing conifer species, but these trees are much more flammable than Canada’s diverse, native forest.

Hedgehogs’ habitat is shrinking, they’re vulnerable to cars, and pesticides are affecting their food supply. Here’s how we can help them pull through
With stumpy, speedy legs, questing snouts and a fierce quiver of needles, hedgehogs are enchantingly strange, like fantasy creatures from a medieval bestiary. “It’s the nation’s favourite wild animal – every time there’s a vote or a poll, the hedgehog wins,” says ecologist Hugh Warwick, AKA “Hedgehog Hugh”, author of the Cull of the Wild and hedgehog champion.

The Quapaw Nation is the only US Native community to carry out a cleanup of one of the country’s worst sites of environmental contamination
They call this land the Laue. In the late 1800s, part of these 200 acres of grassland inside the Quapaw Nation were allotted to tribal citizen Charley Quapaw Blackhawk. After forcing dozens of tribes into Indian territory before the civil war, the US government then parceled out reservations and property to individual members. It was part of the government’s attempt to “civilize” Native Americans by turning them into private, not communal,landholders and yeoman farmers in the model of Thomas Jefferson’s ideal citizen.
Yet, for the last century, little grew on the Laue. Half of it was buried beneath towering mounds of toxic rock known as chat piles. The waste rock, laced with chemicals, was left after miners extracted millions of tons of lead and zinc from the Tri-State Mining District, where the valuable ores stretched across Kansas, Missouri and Oklahomabetween 1891 and the 1970s. By 1983, the Environmental Protection Agency (EPA) had designated 40 sq miles that include nearly all the Quapaw Nation as the Tar Creek Superfund site, joining the EPA’s list of the most contaminated places in the country. Informally called a “megasite”, Tar Creek remains one of the largest and most complex environmental disasters in the country.

Review from non-profit finds range of scenarios of firms simultaneously lobbying for and against Pfas regulations
Some top US lobbying firms are simultaneously working both sides of the Pfas “forever chemicals” issue, raising serious conflict of interest questions and concerns that their activity is slowing states’ efforts to rein in the public health threat.
The review of six states’ lobbying records conducted by the non-profit F-Minus found a range of scenarios in which firms lobbied both sides. Most common Pfas are linked to cancer. The lobbying firm Holland & Knight works for the American Chemistry Council, which represents the nation’s largest Pfas makers, and aggressively opposes most regulations. Simultaneously, Holland & Knight lobbies for the American Cancer Society.

Exclusive: Lough Neagh, which supplies drinking water for 40% of NI, contains genes resistant to last-resort antibiotics
Genes capable of creating antibiotic-resistant superbugs have been detected in the UK’s largest lake, which supplies drinking water to about 40% of Northern Ireland.
Testing of water from Lough Neagh, which has a surface area 26 times bigger than Windermere, found genes resistant to a wide range of antibiotics, including carbapenems – drugs reserved for life-threatening infections when all other treatments have failed.

Ruabon grouse moor, Wrexham: Mating season is upon us. Will I be lucky enough to spot a courtship lek?
I’m shooting grouse on the moor today. There are two kinds here: red grouse, a gamebird reared and shot in its thousands; and its larger, rarer cousin, the black grouse. The latter is supposedly spared by a ban that remains voluntary despite catastrophic declines in recent decades. As it’s not shooting season, which runs from August to mid-December, I shoulder a camera, not a shotgun, hoping to snap one of these increasingly rare birds.
Springtime is when black grouse start to breed, so I arrive before dawn, which is when they lek – a courtship dance where they fan their tails, peck and scuffle with their rivals.

Carmaker’s decision to drop NissanConnect EV app on relatively recent cars fuels warnings from experts
Owners of some Nissan Leaf electric vehicles are angry after the carmaker announced it would shut down an app that lets them remotely control battery charging and other functions.
Drivers of Leaf cars made before May 2019 and the e-NV200 van (produced until 2022) have been told that the NissanConnect EV app linked to their vehicles will “cease operation” from 30 March. This means they will lose remote services, including turning on the heating, and some map features.

Colossal Biosciences’ CEO says its work follows a ‘moral obligation’ while critics say it’s ‘tech bro’ hype that could undermine conservation
Can and should we resurrect animal species that have been extinct for thousands of years? Such weighty, existential questions were once the preserve of science fiction but are now being played out within an unassuming brick building in a Dallas business park.
Colossal Biosciences, valued at $10.2bn after raising hundreds of millions of dollars in funding from investors including celebrities spanning from Tiger Woods to Paris Hilton, has provoked a stampede of acclaim as well as denunciation after announcing last year it had made the dire wolf, a species lost from the world for more than 10,000 years, “de-extinct” via the birth of three new pups.

Mohammed Ahmed Sayed Mohammed is among those redeploying his skills for a local recycling company that is cleaning up the Nile
At 6am, Mohammed Ahmed Sayed Mohammed steers his boat from al-Qarsaya island through Cairo’s Nile waters towards the capital’s riverside clubs. Fifteen years ago, he searched for fish. Now he hunts plastic bottles.
“The fish fled from the plastic chokehold,” said Sayed, who has lived on the Giza island since arriving from Assiut, further south on the Nile, as a 14-year-old fishing apprentice. He never returned to his village, marrying locally and raising three children who now live alongside him with their 12 grandchildren on the island housing 200 families.

Gotovo svi duktalni adenokarcinomi gušterače (PDAC) nastaju aktiviranjem mutacija u onkogenu KRAS, koje se javljaju u više različitih alelnih oblika. Iako su značajni napori doveli do razvoja inhibitora koji ciljaju specifične mutantne KRAS proteine, jedini agensi trenutno odobreni za kliničku upotrebu selektivno ciljaju varijantu KRASG12C. Međutim, mutacije KRASG12C su izuzetno rijetke kod raka gušterače.
Nedostatak vitamina B2 čini tumorske stanice osjetljivijima na jedinstveni oblik stanične smrti, pokazala je nova studija. Ljudsko tijelo ne može samo proizvesti vitamin B2, poznat i kao riboflavin, te ga mora apsorbirati putem prehrane. Vitamin B2 se može naći u mliječnim proizvodima, jajima, mesu i zelenom povrću. Metabolizam ga pretvara u molekule koje, između ostalog, štite stanicu od oksidativnog oštećenja. No, sada je nova studija pokazala da ova funkcija vitamina B2 ima i lošu stranu: također štiti stanice raka. Naime, vitamin B2 igra ključnu ulogu u zaštiti stanica raka od feroptoze, posebnog oblika programirane stanične smrti.
Topikalna krema aktivirala je imunološki odgovor kože i suzbila rast tumora u dva predklinička modela karcinoma pločastih stanica kože (cSCC), jednog od najčešćih karcinoma na svijetu, pokazala je nova studija. Krema, koju su razvili američki znanstvenici s Perelman School of Medicine at the University of Pennsylvania, djeluje blokiranjem LSD1, enzima koji suzbija puteve aktivacije imunološkog sustava u koži.
S više od 100 milijuna neurona u probavnom traktu, crijeva su prepoznata kao drugi mozak, povezujući probavu s fizičkim i mentalnim blagostanjem. Sada, nova studija koju su proveli znanstvenici s Emory University objašnjava vezu između crijeva i mozga, ukazujući na to da žive bakterije iz crijeva mogu izravno ući u mozak, s potencijalnim implikacijama za neurološko zdravlje.
Rezultati kliničkog ispitivanja faze 3 koje su vodili znanstvenici Mass General Brigham pokazuju da lijek romiplostim može učinkovito spriječiti kemoterapiju da uništi stanice koštane srži koje proizvode trombocite, čestu komplikaciju poznatu kao trombocitopenija inducirana kemoterapijom. Romiplostim pojačava sposobnost koštane srži da izdrži napad kemoterapije tako da primatelji lijeka mogu nastaviti proizvoditi trombocite koji su potrebni za sprječavanje krvarenja.
Kronična bubrežna bolest (CKD) pogađa oko 10 do 12 posto odrasle populacije u Hrvatskoj, ali veliki dio oboljelih toga nije svjestan. Upravo zato je rano otkrivanje presudno – jer kada bolest prepoznamo na vrijeme, njezino napredovanje često možemo znatno usporiti ili zaustaviti, izjavio je prof. dr. sc. Ivan Bubić, predsjednik Hrvatskog društva za nefrologiju, dijalizu i transplantaciju Hrvatskog liječničkog zbora, povodom obilježavanja Svjetskog dana bubrega.
Rezultati nove studije pokazuju da dodavanje badema u svakodnevnu prehranu odraslih osoba s pretilošću može poboljšati profile upalnih citokina i kvalitetu prehrane, čak i bez gubitka težine. To ističe jednostavnu prehrambenu strategiju koja može pomoći u rješavanju upale povezane s pretilošću.
Švedski znanstvenici identificirali su protein povezan s povećanim rizikom od metastaza i recidiva raka pluća, što otvara put novim pristupima precizne medicine, posebno za starije pacijente.
Prvo kliničko ispitivanje koje je izravno usporedilo dva uobičajeno korištena lijeka za liječenje venske tromboze pronašlo je jasnog pobjednika: iako oba lijeka dobro djeluju u sprječavanju ponovnih krvnih ugrušaka, apiksaban je sigurniji od rivaroksabana, s manje komplikacija krvarenja.
Raniji početak prvog obroka u danu može promijeniti dnevni ritam glukoze u tijelu i smanjiti razinu glukoze tijekom noći kod gestacijskog dijabetesa, ističući vrijeme obroka kao potencijalni faktor načina života koji vrijedi istražiti u skrbi za trudnoću, ukazuje nova studija.
