But there are alternatives....
Events such as Storm Chandra take a terrible toll on ecosystems, but nature can be part of the solution for mitigating flood waters
“The flood waters are only good for scavenger species,” says Steve Hussey, searching hard for a silver lining to last week’s deluges brought by Storm Chandra. When the waters recede, crows and ravens will feast on the carrion of hedgehogs, dormice and other small animals unable to escape the rising water, he says.
“It sounds very apocalyptic, doesn’t it?” says Hussey, a communications officer with the Devon Wildlife Trust.

Framework Convention on International Tax Cooperation could also force ultra-rich to pay global wealth tax
Fossil fuel companies could be forced to pay some of the price of their damage to the climate, and the ultra-rich subjected to a global wealth tax, if new tax rules are agreed under the UN.
Negotiations on a planned global tax treaty will resume at the UN headquarters in New York on Monday, with dozens of countries supporting stronger rulesthat would make polluters pay for the impact of their activities.

Bruce Friedrich argues the only way to tackle the world’s insatiable but damaging craving for meat is like-for-like replacements like cultivated and plant-based meat
For someone aiming to end the global livestock industry, Bruce Friedrich begins his new book – called Meat – in disarming fashion: “I’m not here to tell anyone what to eat. You won’t find vegetarian or vegan recipes in this book, and you won’t find a single sentence attempting to convince you to eat differently. This book isn’t about policing your plate.”
There’s more. Friedrich, a vegan for almost four decades, says meat is “humanity’s favourite food”.

A wave of affordable Chinese-made EVs is accelerating the shift away from petrol cars, challenging long‑held assumptions about how transport decarbonisation unfolds

Last year, almost every new car sold in Norway, the nature-loving country flush with oil wealth, was fully electric. In prosperous Denmark, which was all-in on petrol and diesel cars until just before Covid, sales of battery electric vehicles (BEVs) reached a share of 68%. In California, the share of zero-emissions vehicles hit 20%. And at least every third new car now bought by the Dutch, Finns, Belgians and Swedes burns no fuel.
These figures, which would have felt fanciful just five years ago, show the rich world leading the shift away from cars that pump out toxic gas and planet-heating pollutants. But a more startling trend is that electric car sales are also racing ahead in many developing countries. While China is known for its embrace of electric vehicles (EVs), demand has also soared in emerging markets from South America to south-east Asia. BEV sales in Turkey have caught up with the EU’s, data published this week shows.

About 190,000 are still without power in the south-east as states scramble to prepare for more winter weather
Dozens of people have died in the teeth of a severe winter storm across the US south, with further freezing temperatures, snow and blizzards set to assail the east coast on Saturday.
At least 85 people have died across multiple states, according to an Associated Press tally, with frigid conditions and icy roads causing car crashes, hypothermia and other fatal incidents.

As rivers swell and homes are cut off, scientists say UK winter rainfall is already 20 years ahead of predictions
When flooding hit the low-lying Somerset Levels in 2014, it took two months for the waters to rise. This week it took two days, said Rebecca Horsington, chair of the Flooding on the Levels Action Group and a born-and-bred resident. A fierce barrage of storms from the Atlantic has drenched south-west England in January, saturating soils and supercharging rivers.

Exclusive: Formal validation for claret reflects hotter conditions, falling consumption and shift towards chillable reds
Bordeaux’s wine industry has historically adapted to consumer habits. In the 1970s the region leaned towards white, but by the 2000s was famed for powerful oak-aged reds.
Now it’s turning to a much older form of red with a name familiar to anglophones: claret. With origins in the 12th century, when it was first shipped to Britain, claret was soon our favoured wine, an unofficial byword for bordeaux red, which in recent decades has become increasingly full-bodied.

Honduras is one of the most dangerous countries for environmentalists – and the release of Juan Orlando Hernández has reinforced its ‘crisis of impunity’, say critics
When Donald Trump announced that he would pardon the former Honduran president Juan Orlando Hernández, only the second world leader to be convicted of drug trafficking, Anna*, an environmental defender, was shocked.
In 2022, Hernández, also known as JOH, was extradited to the US and later convicted, along with his brother, on drug trafficking and weapons charges. He was sentenced to 45 years in prison for conspiring to smuggle more than 400 tonnes of cocaine into the US, becoming the first Honduran head of state to be tried and sentenced abroad for running a narco state. He was also accused of grave human rights violations.

Inspired by YouTube creators, some people are limiting beef to a handful of ‘feast days’ a year to cut their climate impact
“I love beef,” says Vlad Luca, 25. But unlike most other self-proclaimed steak lovers, Vlad eats it only four times a year, on designated “beef days”.
The “beef days” phenomenon has been popularised by the brothers John and Hank Green, known collectively as vlogbrothers on YouTube. John, 48, is better known for his YA fiction, including The Fault in Our Stars, while Hank, 45, is a self-described science communicator and entrepreneur.

Hordom je rijedak tumor karakteriziran lošom prognozom, ograničenim terapijskim mogućnostima i visokom stopom ponovne pojave. Unatoč napretku u onkologiji, učinkoviti tretmani za hordom ostaju ograničeni. Otpornost na konvencionalnu radioterapiju i kemoterapiju ograničava terapijske mogućnosti, a kirurško liječenje često je izazovno zbog blizine tumora kritičnim anatomskim strukturama. Posljedično, identificiranje novih terapijskih ciljeva ključno je za poboljšanje dijagnoze hordoma, strategija liječenja i predviđanja ishoda.
Dodavanje palbocikliba anti-HER2 i endokrinoj terapiji, nakon indukcijske kemoterapije, može odgoditi napredovanje bolesti kod pacijenata s metastatskim rakom dojke pozitivnim na hormonske receptore (HR+) i pozitivnim na receptor 2 humanog epidermalnog faktora rasta (HER2+), pokazala je nova studija. Rezultati su pokazali medijan preživljavanja bez progresije bolesti od 44,3 mjeseca u skupini koja je primala palbociklib, u usporedbi s 29,1 mjesecom u kontrolnoj skupini.
Znanstvenici su razvili način uzgoja visoko specijaliziranog podskupa moždanih živčanih stanica koje su uključene u bolesti motornih neurona i oštećene su kod ozljeda kralježnice. Smatra se, da ovo postignuće postavlja temelje za daljnja istraživanja o tome mogu li ovi molekularno usmjereni neuroni formirati funkcionalne veze u tijelu i za istraživanje njihove potencijalne upotrebe u ljudskim bolestima gdje su kortikospinalni neuroni ugroženi.
Međunarodni tim znanstvenika otkrio je stotine gena i proteina koji vjerojatno igraju uzročnu ulogu u dijabetesu tipa 2, od kojih bi mnogi bili propušteni studijama koje se oslanjaju samo na uzorke krvi. Nova studija pokazuje da su biološki mehanizmi koji leže u osnovi dijabetesa tipa 2 vrlo tkivno specifični i da je genetska raznolikost u populacijama ključna za identificiranje pokretača bolesti.
Nova studija otkriva kako bakterije u crijevima mogu pomoći u određivanju hoće li aminokiselina asparagin iz prehrane hraniti rast tumora ili aktivirati imunološke stanice protiv raka. To crijevni mikrobiom, koji se sastoji od bilijuna mikroorganizama koji žive u crijevima, postavlja kao središnjeg igrača u odgovoru tijela na rak i na moderne tretmane raka poput imunoterapija.
Cerebralna amiloidna angiopatija (CAA) je stanje u kojem se protein (nazvan amiloid) nakuplja u mozgu, slabeći krvne žile. Osobe s cerebralnom amiloidnom angiopatijom imaju četiri puta veću vjerojatnost da će razviti demenciju unutar pet godina, bez obzira na to jesu li imale moždani udar, tvrdi nova studija.
Agregacija proteina tau definira tauopatije, najčešće neurodegenerativne bolesti povezane sa starenjem, koje uključuju Alzheimerovu bolest i frontotemporalnu demenciju. Specifični neuronski podtipovi selektivno su osjetljivi na agregaciju tau proteina, disfunkciju i smrt. No, znanstvenici sa UC San Francisco nedavno su identificirali sakupljač opasnog otpada u mozgu koji odlaže toksične nakupine tau proteina koje mogu dovesti do demencije. Neuroni s više ovog sakupljača otpada, tehnički poznatog kao CUL5, manje su osjetljivi na Alzheimerovu bolest.
Nova studija sugerira da melatonin iz svakodnevne hrane može obilježiti prehrambene obrasce povezane s nižim stopama pretilosti i depresije, a da ne pokazuje jasne veze s drugim kroničnim bolestima. Melatonin, koji se nalazi u hrani životinjskog i biljnog podrijetla, povezan je s koristima za san, raspoloženje i metaboličko zdravlje u eksperimentalnim, opservacijskim i suplementacijskim studijama.
Transplantacija fekalne mikrobiote (FMT) može dramatično poboljšati liječenje raka, sugeriraju rezultati dviju studija. Prva studija pokazuje da se toksične nuspojave lijekova za liječenje raka bubrega mogu eliminirati FMT-om, a druga studija sugerira da je FMT učinkovit u poboljšanju odgovora na imunoterapiju kod pacijenata s rakom pluća i melanomom.
Znanstvenici sa Oregon State University razvili su novi nanomaterijal koji pokreće par kemijskih reakcija unutar stanica raka, ubijajući stanice putem oksidativnog stresa, a zdrava tkiva ostavljajući na miru. Ovi rezultati unapređuju područje kemodinamičke terapije ili CDT-a, novog pristupa liječenju temeljenog na prepoznatljivom biokemijskom okruženju koje se nalazi u stanicama raka.
