But there are alternatives....
Climate change committee finds move to renewable energy would also bring health, economic and security benefits
Achieving the UK’s net zero target by 2050 will cost less than a single oil shock and bring health and economic benefits while insulating the country against future costs, the government’s climate advisers have forecast.
Eliminating the UK’s reliance on fossil fuels by adopting renewable energy and green technologies, such as electric vehicles and heat pumps, would be the best and most cost-effective option for the future economy, the Climate Change Committee (CCC) found.

Analysis has found more than 3,000 mining operations within the most naturally precious areas of the planet, a much bigger footprint than previously thought
Weda Bay is just one example of a global trend that could see the mining industry expand into some of Earth’s last areas of wilderness in search of minerals and materials to feed the global economy.
Analysis produced for the Guardian by a group of academic researchers found more than 3,267 mining operations within key biodiversity areas (KBAs), accounting for nearly 5% of the mining sector’s global footprint. China, Brazil, Argentina and Mexico top the rankings for total surface mining area within key biodiversity areas, the most naturally precious areas of the planet.

Hemmed in by the sea and poor transport links, many young people from the Yorkshire town feel trapped, but there is also a pride in the area
It’s the morning after a wet and stormy day in the Yorkshire seaside town of Scarborough. The waves, which the previous day had been crashing dramatically on the harbour walls, have calmed and a few brave souls have entered the water with surfboards. There is a man throwing a ball for his dog on the beach and a kayaker bobbing on the waves.
Just up from the seafront in the centre of town, Jack and Charlie, both 17, are leaning forward listening to a story from 19-year-old Keane about his recent visit to a drama school in London, where he is hoping to apply for a place on an actor training course once he has saved enough money.
Scarborough, on the North Yorkshire coast, was one of England’s first seaside resorts

Study shows animals hear very high frequencies, making it possible to design a deterrent to cut deaths
Hedgehogs have been discovered to hear high-frequency ultrasound, raising hopes that they could be deterred from dangerous roads with ultrasound repellers.
Vehicles are estimated to kill up to one in three hedgehogs, a big factor in the much-loved mammal’s drastic decline across Europe over recent decades.

They will soon be looking for nest sites to begin the huge effort of raising their brood of between eight and 10 chicks
If there were an award for the most underrated British garden bird, the blue tit may well come out on top. Feisty and fascinating, this colourful little creature is so common and familiar that we often take it for granted.
This could be because of the blue tit’s ubiquity. In both the main garden bird surveys in the UK – the RSPB’s annual Big Garden Birdwatch and the long-running BTO Garden BirdWatch – the species is always in the top five. With roughly 3 million breeding pairs, blue tits are as common in urban and suburban gardens as they are in rural ones.

Knightwood Inclosure, New Forest: I realise my knowledge of my favourite haunt is the size of the spidery-speck hanging in the heather
In soft sunlight the woodland wakes. Brimstone butterflies boast their presence, a raven pair rattle overhead, and the first scents of warming earth drift upwards. Spring shouts its arrival across Knightwood Inclosure, home of the New Forest’s girthiest tree, the Knightwood Oak. It falls on deaf ears though; knelt in mud, immersed in undergrowth, I’m mesmerised in micro.
In front of me, suspended on barely-there thread, hangs a speck of a spider. It was the disco-ball water droplets, clinging to its intricately woven web, that enticed me in. The spider is so small that my eyes and camera struggle to focus, flicking from a cream and tawny-coloured orb to a faded heather flower. When I do lock on, the abdominal markings gain clarity: inky black lines encasing two small spots.

More than 100,000 people have tuned in to watch ‘kākāpō cam’, which captures a rare flightless bird sleeping, tidying her nest and fighting off intruders
On an island in New Zealand’s remote southern fjords, one of the world’s strangest and rarest parrots – the kākāpō – is caring for her tiny chick as fans from across the globe watch on.
Through the black and white lens of a hidden camera, a fluffy orb with a kazoo-like squeak jostles for food from its mother’s beak. The mother, Rakiura, is attentive – scooping her chick under her large green wings, fending off an intruding bird, and periodically tidying her nest.

The Australian artist was a relentless self-promoter, prolific painter and pro wrestler. He loved a tall tale – but his true story was remarkable
If you checked out the Archibald prize finalists back in 1983, one painting in particular might have caught your eye. Taking up seven feet of wall space, Dr Brown and Green Old Time Waltz is a psychedelic portrait of the then Greens leader, Bob Brown, rendered in rich colours and filled with hidden details: from faces smuggled into the trees to little green men walking around Brown’s feet.
But just as noteworthy as the painting was the man standing next to it. Clad in hand-painted clothes, with painted false teeth in his mouth and a walking stick he didn’t really need in his hand, stood Harold “the Kangaroo” Thornton, the artist and self-described “greatest genius that ever lived”.

Recent attack on plants led to fears of escalating strikes, but Iran knows drought has left it equally vulnerable
In 1983, the CIA determined that the most crucial commodity in the Gulf was its desalinated potable water.
Although the loss of a single plant could be handled, “successful attacks on several plants in the most dependent countries could generate a national crisis that could lead to panic flights from the country and civil unrest”. And the greatest threat to the region’s water supply? “Iran.”

Reaching up to 100ft, these massive piles contain tonnes of salt that keep roads clear – but pose environmental risks
Most mountains take tens of millions of years to form. Toronto’s newest mountain took just days.
Towering atop the crowns of evergreens, it has no skeleton of limestone or granite. There are no spires, cornices or headwalls. It is simply piles upon piles of snow, mixed with a toxic cocktail of road salt, antifreeze, oil, coffee cups and lost keys. It is the final resting place for the forces of nature that have battered the city in recent weeks – and a daunting environmental hazard.

Crijevni mikrobiom - bilijuni bakterija i drugih mikroba koji nastanjuju gastrointestinalni trakt - pokreće proces ključan za zaštitu debelog crijeva od ozljeda tkiva, pokazuje nova studija. Smatra se, da ovo otkriće ima važne implikacije za razumijevanje kako se može razviti širok raspon crijevnih poremećaja. Naime, ovo istraživanje otvara vrata tretmanima koji se usredotočuju na obnavljanje ključnih molekularnih signala u osjetljivim dijelovima debelog crijeva.
Američki znanstvenici otkrili su da novi biomarker na bazi krvi može predvidjeti rizik od razvoja demencije kod žene čak 25 godina prije pojave simptoma. Naime, studija, objavljena u JAMA Network Open, pokazuje da su više razine fosforiliranog tau 217 (p-tau217) - proteina povezanog s promjenama u mozgu koje se vide kod Alzheimerove bolesti - bile snažno povezane s budućim blagim kognitivnim oštećenjem i demencijom kod starijih žena koje su bile kognitivno zdrave na početku, što znači na početku studije prije nego što su otkriveni bilo kakvi problemi s pamćenjem ili razmišljanjem.
Vrsta crijevnih bakterija znana kao Roseburia inulinivorans specifično je povezana s ljudskom mišićnom snagom i poboljšanim mišićnim performansama kod miševa, otkriva nedavno objavljeno istraživanje. Naime, pokazalo se, da R. inulinivorans mijenja određene metaboličke procese u mišićima i pretvara mišićna vlakna u brzotrzajuća (tip II) - dizajnirana za kratke intenzivne pokrete, poput sprinta i dizanja utega.
Rezultati nove studije pokazali su da pacijenti s rakom prostate s niskom razinom testosterona mogu imati veći rizik od progresije raka u agresivniji oblik dok su pod aktivnim nadzorom. Rezultati sugeriraju da početna razina testosterona može poslužiti kao koristan klinički marker za bolju stratifikaciju rizika i prilagođavanje strategija praćenja za pacijente koji odabiru aktivni nadzor.
Rezultati novog istraživanja pokazuju da pacijenti koji su preživjeli moždani udar, a pritom su mlađi od 50 godina, imaju više problema s koncentracijom i obavljanjem svakodnevnih poslova te imaju više dana lošeg mentalnog zdravlja nego osobe starije životne dobi koje su preživjele moždani udar.
Sve veći broj istraživanja sugerira da crijevni mikrobiom može utjecati na hormonalne i metaboličke poremećaje koji se javljaju kod sindroma policističnih jajnika (PCOS). Znanstvenici sada predlažu da bi postbiotici, bioaktivni spojevi koje proizvode mikrobi, jednog dana mogli nadopuniti postojeće tretmane vraćanjem mikrobne ravnoteže i poboljšanjem metaboličkog zdravlja.
Varijacije imunoma (imunoloških stanica i funkcija) usko su povezane s ljudskim zdravljem. Različite izloženosti, uključujući vanjsko okruženje i osobni način života, važni su čimbenici koji utječu na imunološki sustav. Sada je nova studija pokazala da su san i prehrana dominantne izloženosti koje utječu na imunom.
Jedna sesija tjelovježbe može potaknuti poticaj neuronske aktivnosti u moždanim mrežama koje su temelj učenja i pamćenja, tvrdi nova studija. Naime, snimke su pokazale povećanu stopu valova koji potječu iz hipokampusa i povezuju se s kortikalnim regijama mozga za koje se zna da su uključene u učenje i pamćenje.
Analiza koju su vodili znanstvenici Mass General Brigham otkrila je sporije starenje kod starijih osoba nakon dvije godine svakodnevnog uzimanja multivitamina, s većim koristima za one koji su započeli ispitivanje s ubrzanom biološkom dobi.
Žene s određenim kardiometaboličkim faktorima rizika, uključujući dijabetes tipa 2 i visoki opseg struka, suočavaju se s većim povećanjem rizika od fibroze jetre nego muškarci s istim faktorima rizika, pokazala je nova studija.
