Born of student disquiet after the 2008 crash, the group says it is reshaping economists’ education
As the fallout from the 2008 global financial crash reverberated around the world, a group of students at Harvard University in the US walked out of their introductory economics class complaining it was teaching a “specific and limited view” that perpetuated “a problematic and inefficient system of economic inequality”.
A few weeks later, on the other side of the Atlantic, economics students at Manchester University in the UK, unhappy that the rigid mathematical formulas they were being taught in the classroom bore little relation to the tumultuous economic fallout they were living through, set up a “post-crash economics society”.

Exclusive: Analysts say there will be oil spill catastrophe that could be far bigger than Exxon Valdez disaster
Decrepit oil tankers in Iran’s sanctions-busting shadow fleet are a “ticking time bomb”, and it is only a matter of time before there is a catastrophic environmental disaster, maritime intelligence analysts have warned.
Such an oil spill could be far bigger than the 1989 Exxon Valdez disaster that released 37,000 tonnes of crude oil into the sea, they said.

Birdwatchers flock to Montréal for rare sighting of ‘vagrant’ bird that has made its home during a bitterly cold winter
On a quiet Montréal street of low-rise brick apartment buildings on one side and cement barrier wall on the other, a crowd has gathered, binoculars around their necks and cameras at the ready. A European robin has taken up residence in the neighbourhood, which is sandwiched between two industrial areas with warehouses and railway lines and, a few blocks away, port facilities on the St Lawrence River.
Ron Vandebeek from Ottawa, Ontario, is here on a frigid February morning hoping to see the rare bird, which was first spotted at the beginning of January.

Abbeydale, Sheffield: I’m genuinely scared when I wake at 2am to the sound of screaming. Then I see two male badgers in an almighty scrap
Fast asleep, my dreamworld takes an unexpected swerve as raucous screaming erupts outside the open bedroom window. For a moment, I assume this is imagined, some emotional outburst from my subconscious. Then I realise that I’m awake. This is real. I check the time: 2am. The screaming continues. In fact, it’s now louder and somehow more intense. The back of the house is woodland, and noises off are common enough. A fox barking. Robin song that eases those anxious, wakeful stretches of the night. But this is something else altogether. This is violence.
My heart is racing now. I fear someone is being attacked, and from the pitch of the screaming, a woman. Mercifully, I soon discount this. My startled mind then suggests a catfight, but the sound I’m hearing is too big for that. So, despite the freezing cold beyond the duvet, I hop out of bed, pull back a curtain and stick my head outside.

In Lancashire, I met people living with dangerous levels of Pfas, including in their food. The government is failing them
Last week, on the morning the government published its Pfas action plan, I got a worried phone call from a woman called Sam who lives next door to a chemical factory in Lancashire. Sam had just been hand-delivered a letter from her local council informing her that after testing, it had been confirmed that her ducks’ eggs, reared in her garden in Thornton-Cleveleys, near Blackpool, are contaminated with Pfas.
Pfas – per- and poly-fluoroalkyl substances, commonly known as “forever chemicals” due to their persistence in the environment – are a family of thousands of chemicals, and I have been reporting on them for years. Some, including those found in the eggs Sam and her family have been eating, have been linked to a wide range of serious illnesses, including certain cancers.

Release into Helman Tor reserve marks historical first for keystone species hunted to extinction in UK 400 years ago
Shivering and rain-drenched at the side of a pond in Cornwall, a huddle of people watched in hushed silence as a beaver took its first tentative steps into its new habitat. As it dived into the water with a determined “plop” and began swimming laps, the suspense broke and everyone looked around, grinning.
The soggy but momentous occasion marks the first time in English history that beavers have been legally released into a river system, almost one year after the government finally agreed to grant licences for releases.

It has rained in parts of the country every day of the year so far and downpours are expected to continue this week
In a “miserable and relentlessly wet” start to the year, rain has fallen somewhere in the UK every single day for weeks on end.
With more than 100 flood warnings in force across the country and further downpours forecast this week, scientists say the atmospheric forces behind Britain’s endless drizzle are the same ones driving devastating floods across Spain and Portugal.

Vast flocks of birds return to Somerset and a rare grebe turns an ordinary walk into something special
After weeks of heavy rain, Cheddar reservoir in Somerset is finally full again – of water, and of birds. Thousands of coots, hundreds of gulls and ducks, and dozens of great crested grebes crowd the surface, some already moulting into their smart breeding plumage, crests and all.
They feed almost constantly, building up energy reserves for the breeding season. Among the throng are some less familiar visitors: a flock of scaup, the males bulkier than the nearby tufted ducks, with pale grey backs that catch the light. Flocks of goosanders dive frequently for food, the colourful males looking like a cormorant in extravagant drag.

Emissions have plunged 75% since communist times in the birthplace of big oil – but for some the transition has been brutal
Once the frozen fields outside Bucharest have thawed, workers will assemble the largest solar farm in Europe: one million photovoltaic panels backed by batteries to power homes after sunset. But the 760MW project in southern Romania will not hold the title for long. In the north-west, authorities have approved a bigger plant that will boast a capacity of 1GW.
The sun-lit plots of silicone and glass will join a slew of projects that have rendered the Romanian economy unrecognisable from its polluted state when communism ended. They include an onshore windfarm near the Black Sea that for several years was Europe’s biggest, a nuclear power plant by the Danube whose lifetime is being extended by 30 years, and a fast-spreading patchwork of solar panels topping homes and shops across the country.

US courts, scholars and Democrats are pushing back against the president’s aggressive drive to boost fossil fuels
Donald Trump’s aggressive drive to boost fossil fuels, including dirty coal, coupled with his administration’s moves to roll back wind and solar power, face mounting fire from courts, scholars and Democrats for raising the cost of electricity and worsening the climate crisis.
Four judges, including a Trump appointee, in recent weeks have issued temporary injunctions against interior department moves to halt work on five offshore wind projects in Virginia, New York and New England, which have cost billions of dollars and are far along in development.

Dijabetes tipa 2 i visoki krvni tlak (hipertenzija) dijele genetsku vezu, pokazuje novo istraživanje. Naime, ljudi s jednim stanjem imaju veću vjerojatnost da će razviti drugo stanje.
Znanstvenici sa Åbo Akademi Universityi identificirali su novu molekularnu promjenu kod pacijenata s rakom debelog crijeva i razvili genetski model bolesti koji stvara tumore u debelom crijevu, slične onima koji se vide kod pacijenata. Ovaj novi model pomaže znanstvenicima da bolje razumiju kako se bolest razvija i podržava potragu za novim tretmanima.
Nova studija upozorava da dugotrajna primjena inhibitora protonske pumpe (PPI) može oštetiti apsorpciju hranjivih tvari. Inhibitori protonske pumpe su klasa lijekova koja uključuje lijekove poput omeprazola, pantoprazola, rabeprazola, lansoprazola i esomeprazola. Koriste se za liječenje želučanih poremećaja. Njihova neprimjerena primjena dulje od preporučenih od strane liječnika može uzrokovati nutritivne nedostatke, poput anemije, i ugroziti zdravlje kostiju.
Rezultati nove studije otkrivaju kako imunološke stanice u mozgu odraslih osoba mogu regulirati stvaranje novih neurona. Ovo otkriće vodi do novog razumijevanja kako imunološke stanice mogu utjecati na neurogenezu odraslih, proces stvaranja novih neurona u mozgu. Neuroni su temeljni prijenosnici informacija u mozgu, a imunološke stanice provode nadzor i šalju poruke novim neuronima.
Prema rezultatima nove studije, izgleda da vremenski ograničeno hranjenje - oblik povremenog posta - značajno smanjuje simptomatsku aktivnost bolesti i sustavnu upalu kod odraslih s Crohnovom bolešću i prekomjernom tjelesnom težinom ili pretilošću. Ovo je prva studija koja pokazuje da jedenje samo unutar 8-satnog prozora može smanjiti aktivnost Crohnove bolesti za 40% i nelagodu u trbuhu za 50% u samo 12 tjedana, u usporedbi sa standardnim rasporedom prehrane.
Skupina lijekova koji se često koriste za liječenje dijabetesa također može pomoći u zaštiti bubrega koji stare, tvrdi nova studija. Naime, nedavno objavljena studija je testirala lijekove nazvane SGLT2 inhibitori kod afričke tirkizne killifish, male ribe koja živi samo 4 do 6 mjeseci. Budući da ribe tako brzo stare, znanstvenici su mogli promatrati ekvivalent desetljeća starenja organa u samo nekoliko tjedana. Rezultati su pokazali da ribe kojima su davani spomenuti lijekovi imaju zdravije bubrege kako stare.
Nova studija sugerira da bi tjelesna aktivnost nakon liječenja poremećaja srčanog ritma znanog kao fibrilacija atrija mogla značajno smanjiti rizik od povratka atrijske fibrilacije (AF), nudeći pacijentima jednostavan i jeftin način podrške dugoročnom zdravlju srca.
Eksperimentalnii lijek protiv zgrušavanja, asundeksian, pokazao je smanjenje rizika od drugog ishemijskog moždanog udara bez izazivanja zabrinutosti zbog krvarenja, tvrde preliminarni rezultati studije. Asundeksian ima potencijal dugoročno smanjiti rizik od ponovnog moždanog udara bez povećanog sigurnosnog rizika, što predstavlja veliki napredak u sposobnosti sprječavanja moždanih udara kod ljudi s rizikom od ponovnog pojavljivanja moždanog udara.
Novo istraživanje sugerira da jetra igra prethodno neprepoznatu ulogu u zdravlju kostiju, ali samo kod muškaraca. Naime, otkriveno je da protein koji se proizvodi u jetri pomaže u regulaciji rasta kostiju kod mužjaka miševa, ali ne i kod ženki. Rezultati bi mogli pomoći objasniti zašto muškarci s bolestima jetre imaju veću vjerojatnost gubitka koštane mase.
U SAD-u će jedna od osam žena oboljeti od raka dojke tijekom života, a otprilike polovica njih će imati mastektomiju. Mnoge od tih žena odlučuju se za kiruršku rekonstrukciju dojki, najčešće implantatima, ali relativno visok postotak razvija infekcije nakon operacije, što zahtijeva intravenske antibiotike i često uklanjanje implantata. To može dovesti do dodatnih operacija, kašnjenja u liječenju raka i povećanih troškova, kao i dodatne emocionalne nevolje za žene koje su već pod pritiskom dijagnoze i liječenja raka.
