But there are alternatives....
Under outgoing mayor Anne Hidalgo, the French capital added bike lanes, cut traffic and reclaimed public space, but not without resistance
When Corentin Roudaut moved to Paris 10 years ago, he was too scared to cycle. The IT developer had biked everywhere as a student in Rennes but felt overwhelmed by the bustling French capital. Cars were everywhere. Cyclists had almost no protection.
But once authorities carved out space for a segregated bike lane on Boulevard Voltaire near his home in the 11th arrondissement, Roudaut returned to the two-wheel commute and did not look back. He now volunteers with Paris en Selle, a cycling campaign group, and has watched with wonder as the city has shaken off its car-centric reputation.

Exclusive: research finds Jackdaw field would provide only about 2% of current demand, and Rosebank only 1%
Opening major new fields in the North Sea would make almost no difference to the UK’s reliance on gas imports, research has shown.
The Jackdaw field, one of the largest unexploited gasfields in the North Sea, would displace only 2% of the UK’s current imports of gas, which would leave the UK still almost entirely dependent on supplies from Norway and a few other sources.

In turbulent times, experts recommend building up a store of food if possible – focusing on long-life, no-cook items
People should have an emergency stockpile of food in their homes in case conflicts, extreme weather or cyber-attacks shut down supplies, leading UK experts have told the Guardian.
In an ever more turbulent world, they say it is essential to choose long-life items that can be eaten without cooking – think tinned beans, vegetables and fish, rice crackers, and oats that can be soaked. But it is also important to choose items you actually like to eat, and some treats such as chocolate or crisps to keep your spirits up. You will also need water – lots of it – not just to drink but for washing too.

Researchers are weaving Native practices with western methods to revive ecosystems and reclaim food sovereignty
“I’m a glorified clam counter.”
So said Marco Hatch, a marine ecologist at Western Washington University and an enrolled member of the Samish Indian Nation. Hatch has been conducting surveys of mollusks growing in and around clam gardens in the Pacific north-west, as he collaborates with seven Indigenous communities to build or rebuild these rock-walled, terraced beaches once created and tended by their ancestors.

Citizen science data reveals early flowering, nesting and insect activity as global heating accelerate seasonal change
Bluebells are flowering, swallows are returning and orange-tip butterflies are flying in what could become Britain’s earliest recorded spring.
Records for early spring occurrences are being smashed as 2026 looks to be the earliest this century for frogspawn laying, blackbirds nesting, brimstone butterflies emerging and hazel flowering, according to Nature’s Calendar, which has logged citizen science records of seasonal change since 2000.

Former government adviser Polly Billington urges bigger steps to shield people in UK from effects of Iran war
Keir Starmer should convene a global energy summit of the same order as Gordon Brown’s response to the 2008 financial crisis and put Britain on a “war footing” to reduce its exposure to fossil fuels, a Labour MP and former government adviser has said.
Polly Billington, who was an aide in Brown’s government, warned that economic pain was “hurtling down the tracks” and a bigger response was needed to protect the British people from the consequences of the US-Israeli war on Iran.

Sgòr Gaoith, Cairngorms: Our rucksacks are heavy with crampons and ice axe, and the wind is a menace, but it’s all worth it for the views
The weather app shows wall-to-wall spiky yellow suns. We haven’t had a day like this in over a month, nor is one foretold in the weeks to come, so I abandon the desk and, with a friend and a dog, head for the hills.
We choose Sgòr Gaoith, the high point of the ridge above the River Feshie which forms the western edge of the Cairngorms. Our path starts in Scots Pine forest, where we walk in dappled light and can hear the soft chuckle of Allt Ruadh, the Red Burn. The trees thin as we gain height, but everywhere, new saplings are appearing across this once bare landscape and you can almost feel the rising of life. Our rucksacks are heavy with crampons and ice axe – just in case – but the air is fresh and spangling as the sun pours down the brown slopes and into our winter-dull eyes.

Hamburg shop set up in tribute to aspiring pastry chef becomes ‘happy’ pilgrimage site for grieving parents
Johanna Orth was a fun-loving, determined little girl and later a purpose-driven young woman who revelled in making a creative mess in the kitchen. Her parents, Inka and Ralph, chuckle quietly as they remember the stacks of batter-covered bowls, spatulas and whisks repeatedly left in the sink.
With time, Johanna’s cakes and pastries grew more sophisticated and elaborate, guided by her grandmother, Marlies, who was also a talented baker. Marlies’ own ambition of opening a cafe one day had been thwarted by the demands of motherhood and postwar Germany’s rigid gender roles.

In this week’s newsletter: From pollution in the upper atmosphere to mounting debris, experts warn the rapid expansion in space could threaten our planet

Our relationship with space is changing rapidly.
For almost all of human history, the space above us was an unreachable frontier. Yet in a single human lifetime, Earth’s orbit has gone from largely empty to congested with satellites.

Study shows reducing vulnerability to pollution, including by expanding healthcare access, saves millions of lives
Reductions in vulnerability to air pollution since 1990 saved the lives of about 1.7 million people in 2019, according to new research.
Particle pollution improved in 139 out of 193 countries. The greatest gains were achieved in Europe and North America, with smaller reductions across Africa and Asia.

Tumori uzrokovani mutacijama KRAS gena koje uzrokuju rak često su podložni feroptozi, vrsti stanične smrti koja se može iskoristiti za terapiju raka. S obzirom na to da više od 95% duktalnih adenokarcinoma gušterače sadrži takve mutacije, moglo bi se očekivati da će ovi tumori biti slično ranjivi. No, ipak, ti tumori ne pokazuju takvu ranjivost.
Nova studija znanstvenika s University of Texas MD Anderson Cancer Center pokazuje da specijalizirana vrsta zračenja s visokim dozama može značajno poboljšati ishode za pacijente s velikim tumorima žučnih vodova u jetri, poznatim kao intrahepatični kolangiokarcinom.
Ljudi mogu pretpostaviti da ako piju malo alkohola tijekom tjedna ili mjeseca, prekomjerno pijenje povremeno petkom ili subotom možda neće uzrokovati oštećenje jetre. No, novo istraživanje sugerira drugačije.
Novo istraživanje pokazuje da osobe koje žive s opstruktivnom apnejom u snu imaju 71% veći rizik od kardiovaskularnih događaja ili smrti od bilo kojeg uzroka u usporedbi s osobama koje nemaju sleep apneju.
Istraživanje provedeno u SAD-u pokazuje da tjelesna težina, san, pušenje i tjelesna aktivnost mogu biti važniji za hipertenziju od samog ukupnog rezultata prehrane, pri čemu se natrij i dalje ističe kao važan prehrambeni čimbenik.
Multidisciplinarni stručni panel tvrdi da se obični, nezaslađeni jogurt može kod djece uvesti od 6 mjeseci kao dio dopunske prehrane, nudeći korisne hranjive tvari i žive mikroorganizme, a istovremeno pomaže u razbijanju uobičajenih mitova o mliječnim proizvodima kod dojenčadi.
Viša razina vitamina D u krvi u srednjoj životnoj dobi povezana je s nižim razinama tau proteina u mozgu, što je znak demencije, godinama kasnije, pokazuje nova studija. Studija ne dokazuje da razina vitamina D smanjuje razinu tau proteina i rizik od demencije; samo pokazuje povezanost.
Nemogućnost priuštiti si dentalnu skrb može povećati rizik od razvoja kardiovaskularnih bolesti ili demencije, tvrdi nova studija. Naime, pokazalo se, da starije osobe koje odustaju od potrebnih stomatoloških zahvata zbog financijskih prepreka mogu imati veću vjerojatnost da će doživjeti zatajenje srca, srčani udar, moždani udarili demenciju.
Prema rezultatima nove studije, jednostavan dodatak vlakana mogao bi preoblikovati crijevni mikrobiom, stabilizirati skokove šećera u krvi, pa čak i spriječiti prijevremeni porod u trudnoćama visokog rizika, nudeći obećavajući novi put za preciznu prenatalnu skrb.
Test krvi mogao bi pomoći u identificiranju osoba s većim rizikom od kognitivnog pada godinama prije nego što je moguća tradicionalna dijagnoza, tvrde znanstvenici s University of East Anglia. Naime, oni su otkrili da suptilne promjene u krvi mogu otkriti najranije znakove kognitivnog pada mnogo prije nego što simptomi postanu očiti. Te promjene uzrokuju kemikalije koje proizvode crijevne bakterije - što pojačava tezu da veza crijeva i mozga igra važnu ulogu u ranim promjenama pamćenja.
