Fifteen years after a tsunami caused the Fukushima nuclear accident, only bears, raccoons and boar are seen on the streets. But the authorities and some locals want people to move back
Norio Kimura pauses to gaze through the dirt-flecked window of Kumamachi primary school in Fukushima. Inside, there are still textbooks lying on the desks, pencil cases are strewn across the floor; empty bento boxes that were never taken home.
Along the corridor, shoes line the route the children took when they fled, some still in their indoor plimsolls, as their town was rocked by a magnitude-9 earthquake on the afternoon of 11 March 2011 which went on to cause the world’s worst nuclear disaster since Chornobyl.

Scientists expect 41% of the projected global population to face the extremes, with ‘no part of the world’ immune
The number of people living with extreme heat will more than double by 2050 if global heating reaches 2C, according to a new study that shows how the energy demands for air conditioners and heating systems are expected to change across the world.
No region will escape the impact, say the authors. Although the tropics and southern hemisphere will be worst affected by rising heat, the countries in the north will also find it difficult to adapt because their built environments are primarily designed to deal with a cooler climate.

Initiatives such as London’s ULEZ can be a model for other cities. But even more could be done to save lives and protect us from deadly toxins in the air
Breathwork is everywhere, whether it’s in yoga studios, corporate retreats or self-help reels. We’re told to “just breathe”. Be mindful. Lower our stress levels. Inhale. Exhale. In the yogic tradition, bringing clean air into our lungs and our body (pranayama in Sanskrit) is about purifying and detoxing, and then exhaling what we don’t need. That all sounds great if you live on a remote island or in the middle of a forest – but what if that air isn’t cleansing us, but making us sick?
According to the World Health Organization, 99% of the global population is exposed to air-pollution levels that exceed its health-based guidelines and air pollution is now the world’s single largest environmental risk, linked to nearly 7 million premature deaths each year. This isn’t an issue of future climate collapse or one that will affect future generations. This is about today – and the damage polluted air is doing to our hearts, lungs, brains and blood vessels.

Funding cuts, conspiracy theories and ‘powder keg’ pine plantations have seen January’s forest fires tear through Chubut in southern Argentina
Lucas Chiappe had known for a long time that the fire was coming. For decades, the environmentalist had warned that replacing native trees in the Andes mountain range with highly flammable foreign pine was a recipe for disaster.
In early January, flames raced down the Pirque hill and edged closer to his home in the Patagonian town of Epuyén, Argentina, where he had lived since the 1970s. Thirty people with six motor pumps fought for hours, hoses stretched for kilometres, but “there was no way”.

Ripon City Wetlands and Welburn, North Yorkshire: First a starling and then a robin arrived like visitations. I am truly grateful for them both
I’ve heard it said that birds come to people who’ve lost someone dear. It seemed a nice thing to believe, but I never really imagined it might be true. But neither did I imagine losing my only sibling at the age of 53. Nic’s childhood nickname, Twinkle, was apt. She was the brightest, kindest person I’ve ever known, and the ferocity of the cancer that took her in barely a month just before Christmas blindsided us all.
A few days after she slipped away, we went with friends to watch a starling murmuration. It’s something we do most years, but never before have we seen a bird tumble from the throng and crash at our feet like a feathered meteorite. I scooped her into my hat. Sometimes all a stunned bird needs to recover is a warm, safe place to rest. But it wasn’t to be, and so now that impossibly beautiful body is buried* under our damson tree. Star. Sister. Bird. Blossom. All the same interchangeable stuff.

Britain among 10 countries to build 100GW grid in North Sea linking countries through subsea cables
The German chancellor, Friedrich Merz, has said he wants the North Sea to become the “largest reservoir of clean energy worldwide”, as he announced plans to accelerate efforts to link up offshore wind power projects with Europe.
The UK and nine other European countries have agreed to accelerate the rollout of offshore windfarms in the 2030s and build a power grid in the North Sea, in a landmark pact to turn the ageing oil basin into a “clean energy reservoir”.

After debris balls closed Sydney beaches in October 2024, Guardian Australia reported they could be linked to sewage outfalls. Authorities were less keen to talk

Last week, after torrential rain in Sydney, fresh poo balls washed up on the beach at Malabar, the closest beach to the problematic Malabar sewage treatment plant.
Signs were erected on the beach warning people not to touch the “debris balls” or swim. But authorities didn’t let the wider community know. There were no other warnings issued by Sydney Water, the Environment Protection Authority (EPA) or the state government.

As the temperature nears 49C in the Mallee region, residents take refuge in air-conditioned rooms

In the slanting, late-afternoon summer sun, the fields around the small Australian town of Ouyen – almost 450km north-west of Melbourne – turn the colour of honey. The edges shimmer with silver, that old cruel trick of feigning water where it hasn’t rained for weeks.
Summer is always hot out here in the sparse, flat Mallee, but this year is shaping up to be particularly harsh. Just two weeks ago, on Thursday 8 January, Ouyen got to 47.5C. On Monday it reached 44.3C.

As a lifelong Canadian, I’m no stranger to that familiar sinking feeling in my chest as the days get shorter, dimmer and colder. I suffer from seasonal affective disorder (Sad), which also affects about one in 20 people in the US.
“Sad is a type of depression that happens at certain times of the year, usually in the fall and winter when there’s less sunlight,” said Dr Stefanie Mazer, a licensed psychologist and founder of the psychology practice Mindwise, Inc. Changes in sunlight can affect your body’s internal clock and levels of serotonin and melatonin, which influence mood and sleep, Mazer explained. People with Sad often feel low energy, sadness and irritability, with noticeable changes in sleeping or eating.

Nova studija identificirala je albumin, najzastupljeniji protein u ljudskoj krvi, kao snažnu i prethodno neprepoznatu obranu od mukormikoze, rijetke, ali često smrtonosne gljivične infekcije. Mukormikoza, ponekad nazvana crna gljivica, brzo se širi infekcijom uzrokovanom gljivicama Mucorales i može biti smrtonosna kod čak polovice oboljelih pacijenata, a u nekim slučajevima dijagnoza mukormikoze nosi prognozu sigurne smrti.
Više od 25% trudnica ili žena nakon poroda koje su pretrpjele akutni moždani udar imale su susrete s pružateljima zdravstvene skrbi zbog simptoma povezanih s moždanim udarom u prethodnom mjesecu, no nisu dobile pravovremenu dijagnozu, pokazala je nova studija.
Menopauza je povezana sa smanjenjem volumena sive tvari u ključnim regijama mozga, kao i s povećanom razinom anksioznosti i depresije te poteškoćama sa spavanjem, pokazala je nova britanska studija. Jednako tako, pokazalo se, da hormonska nadomjesna terapija (HRT) ne ublažava te učinke, iako može usporiti pad vremena reakcije.
Rezultati nove studije otkrili su da lijekovi koji se koriste za liječenje gihta također mogu smanjiti rizik od srčanog udara (infarkta miokarda) i moždanog udara kod osoba s gihtom. Naime, liječenje gihta s ciljem postizanja ciljane razine urata u krvi također sprječava srčane i moždane udare.
Smanjenje natrija u pakiranoj i pripremljenoj hrani moglo bi značajno poboljšati kardiovaskularno zdravlje i spriječiti mnoge slučajeve bolesti srca, moždanog udara i smrti u općoj populaciji, tvrde rezultati dviju studija.
Novo istraživanje otkriva da je veća konzumacija alkohola tijekom života povezana s većim rizikom od raka debelog crijeva, posebno raka rektuma, te da prestanak konzumacije alkohola može smanjiti taj rizik. Naime, trenutni konzumenti alkohola s prosječnim cjeloživotnim unosom alkohola od ≥14 pića tjedno imali su 25% veći rizik od razvoja raka debelog crijeva i 95% veći rizik od razvoja raka rektuma u usporedbi s onima s prosječnim cjeloživotnim unosom alkohola od <1 pića tjedno.
Pseudomonas aeruginosa je najčešći patogen odgovoran za perzistentne plućne infekcije. Poznato je da se koncentracije željeza u ljudskim plućima znatno razlikuju između zdravstvenog stanja i stanja bolesti. Sada su rezultati nove studije pokazali da željezo iz okoliša olakšava rast i stvaranje biofilma P. aeruginosa koja uzrokuje plućne infekcije, a istovremeno smanjuje njezinu virulenciju. Ova prilagodba posredovana željezom može biti povezana s perzistencijom plućnih infekcija P. aeruginosa, a ovi rezultati zaslužuju daljnja istraživanja.
Pregled više studija ukazuje da su ponavljajuće promjene u crijevnom mikrobiomu povezane s blagim kognitivnim oštećenjem (MCI) i Alzheimerovom bolešću (AD). Istraživanje Alzheimerove bolesti tradicionalno se usredotočuje na genetiku i patologiju mozga, ali sada postoji sve veći interes za to kako crijevni mikrobiom može utjecati na imunitet, metabolizam i moždanu signalizaciju. Disbioza, definirana kao neravnoteža u mikrobiomu, povezana je s upalom i disfunkcijom mozga.
Prema rezultatima nove studije, pušenje cigareta prije 20. godine ostavlja trajan kardiovaskularni učinak, pojačavajući štetu od pušenja i povećavajući rizik od srčanog udara (infarkta miokarda), moždanog udara i rane smrti u odrasloj dobi.
Dvije nedavno objavljene studije ističu ulogu gena zvanog PTPN2 u zaštiti crijeva od štetnih bakterija povezanih s upalnom bolešću crijeva (IBD). Naime, one pokazuju da kada PTPN2 ne funkcionira ispravno, crijeva postaju osjetljivija na infekcije i upale.
