‘On a knife edge’: can England’s red squirrel population be saved?
Government plans to protect species by increasing woodland and removing greys, but campaigners say it needs to go further
When Sam Beaumont sees a flash of red up a tree on his Lake District farm, he feels a swell of pride. He’s one of the few people in England who gets to see red squirrels in his back garden.
“I feel very lucky to have them on the farm. It’s an important thing to try and keep a healthy population of them. They are absolutely beautiful,” he said.

‘Quality really matters’: why the organic food market is booming again
Greater awareness of healthy diets and concerns over ‘trusted’ food mean sales are growing at fastest pace in two decades
When household finances were plunged into turmoil during the credit crunch, one of the first things that Britons cancelled was their veg box delivery.
But although the cost of living crisis persists, the organic market is enjoying its biggest boom in two decades, according to the veg box seller Riverford. It is not just fruit and veg, with a “massive” increase in sales of organic meat. Organic chicken was up 13% year on year, despite costing three times as much as other birds.

Wood burners may treble children’s exposure to pollution in homes, study finds
Research in Wales found that home, not outdoor travel, was largest contributor to children’s daily exposure
Children living in homes with wood burners could be exposed to over three times more pollution than those in non-wood-burning homes. The results come from a study that looked at air pollution experienced by primary schoolchildren in Wales.
Fifty-three children from two primary schools in Anglesey (Ynys Môn) were given backpacks equipped with air pollution sensors. They took the packs home and carried them during their journeys to and from school.

What Trump’s plans for the Arctic mean for the global climate crisis
With plans to sell off over a million acres of natural habitat for oil and gas development, the Trump administration is ignoring the dire impact on its fragile ecosystem
• Don’t get Down to Earth delivered to your inbox? Sign up here
This week, the Trump administration took a key step towards opening new leases for oil and gas drilling across millions of acres in the Arctic National Wildlife Refuge – a pristine and biodiverse expanse in northern Alaska and one of the last wildlands in the US still left untouched.
With a call for nominations officially issued on Tuesday, the US Bureau of Land Management began evaluating plots across the 1.5 million-acre Coastal Plain at the heart of the refuge – an area often referred to as the American Serengeti, thanks to its rich tundra ecosystems, which provide habitat for close to 200 species and serve as the traditional homelands of the Iñupiat and Gwichʼin peoples.

‘We can learn from the old’: how architects are returning to the earth to build homes for the future
Rammed earth sourced from, or near, the grounds of a proposed building site is attracting attention as an eco-friendly construction material
From afar, the low-rise homestead perched in the Wiltshire countryside may look like any other rural outpost, but step closer and the texture of the walls reveal something distinct from the usual facade of cement, brick and steel.
The Rammed Earth House in Cranborne Chase is one of the few projects in the UK that has been made by unstabilised rammed earth – a building material that consists entirely of compacted earth and which has been used as far back as the Neolithic period.

Country diary: A trip to the sheep auction – interrupted by light and legend | Andrea Meanwell
Hawes, North Yorkshire: A stunning ray of sunshine, beamed on to a farmhouse, is a reminder of my family’s history in this landscape
It is early Saturday morning and I’m on my way to the Hawes Honeys sale of “in-lamb” (pregnant) ewes at Hawes auction. Usually I drive through Nateby and up over the tops into North Yorkshire, past the big pipe under the road where I used to play with toy cars when I was little, and remembering my sons shouting “hold your breath everyone, don’t breathe the Yorkshire air” as we passed the county boundary.
Today I take a different route, turning off at Wharton to go via Mallerstang instead. As I drove into Mallerstang I had to stop the car and watch as a single ray of sunlight broke through, lighting up a white farmhouse on the other side of the valley, opposite Pendragon Castle.

Roses are red, violets are blue: why Valentine’s Day flowers need a redo
What could be more romantic than those three little words: locally grown, seasonal? How to choose flowers that show you care – about both a Valentine and Australia’s environment
Change by degrees offers life hacks and sustainable living tips each Saturday to help reduce your household’s carbon footprint

A dozen red roses may say “I love you”, but many conventional bouquets carry an environmental price, having been imported by air, dipped in chemicals and wrapped in plastic.
Valentine’s Day is second only to Mother’s Day for sales of cut flowers, a popular choice for the millions of Australians planning to buy gifts for that special someone.

Postcard-pretty … and filled with pollution: how Brazil’s fishers are reviving Rio de Janeiro’s famous bay
A mangrove conservation project in Guanabara Bay has shown how a dying ecosystem can be transformed into a thriving sanctuary
With deep blue waters flanked by dramatic peaks, Guanabara Bay is the postcard view of Rio de Janeiro – but it is also one of Brazil’s most polluted coastal environments. Raw sewage and solid waste flow into the bay from surrounding cities, home to more than 8 million people. Cargo ships and oil platforms chug in and out of commercial ports, while dozens of abandoned vessels lie rotting in the water.
But at the head of the bay, between the cities of Itaboraí and Magé, the environment feels different. The air is purer, the waters are empty but for small fishing canoes, and flocks of birds soar overhead.

Protein dobiven iz jetre podržava zdravlje kostiju kod muškaraca
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.

Rani biomarkeri predviđaju infekcije nakon operacije rekonstrukcije dojke
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.

Disleksija povezana sa širim ranjivostima moždane mreže
Američki znanstvenici osporavaju ideju da disleksija, ili specifični poremećaj čitanja, proizlazi iz jednog neispravnog gena u mozgu, sugerirajući umjesto toga da je uzrokovana ukupnom ranjivošću moždane mreže. Ovaj uvid mijenja razumijevanje jednog od najčešćih poremećaja učenja na svijetu, koji pogađa do 20% svjetske populacije - gotovo 780 milijuna ljudi koji se suočavaju s cjeloživotnim izazovima s čitanjem.

Implantati matičnih stanica imaju za cilj vratiti dopamin kod Parkinsonove bolesti
Parkinsonova bolest je progresivni neurodegenerativni poremećaj koji pogađa više od milijun ljudi u SAD-u, s otprilike 90.000 novih slučajeva dijagnosticiranih svake godine. Iako dostupni tretmani mogu pomoći u upravljanju simptomima, trenutno ne postoji lijek ili terapija za koju je dokazano da usporava napredovanje bolesti.

Ulcerozni proktitis nije povezan s povećanim rizikom od raka rektuma
Osobe s ulceroznim proktitisom, blažim i ograničenijim oblikom ulceroznog kolitisa, nemaju veći rizik od razvoja raka rektuma od opće populacije, tvrde rezultati švedske studije. Smatra se, da ovo otkriće može doprinijeti individualiziranijem praćenju pacijenata s upalnom bolešću crijeva.

Mediteranska prehrana može zaštititi žene od svih vrsta moždanog udara
Pridržavanje mediteranske prehrane povezano je s nižim rizikom od svih vrsta moždanog udara među ženama, tvrdi nova studija. Valja istaknuti, da studija ne dokazuje da je mediteranska prehrana uzrok nižeg rizika od moždanog udara; samo pokazuje povezanost.

Testiranje menstrualne krvi može poslužiti za probir raka vrata maternice
Testiranje menstrualne krvi na humani papiloma virus (HPV) moglo bi biti dobra alternativa ili zamjena za trenutni probir raka vrata maternice koji provode kliničari, otkriva nova studija. Naime, korištenje menstrualne krvi za testiranje na HPV je praktično i neinvazivno, što ženama omogućuje prikupljanje uzoraka kod kuće, te bi stoga moglo ponuditi praktičan put za proširenje pristupa probiru.

Hormonska terapija smanjuje abnormalni rast živaca kod kronične boli u leđima
Bol u donjem dijelu leđa jedan je od najčešćih zdravstvenih problema u svijetu, koji pogađa ljude svih dobnih skupina i predstavlja veliko opterećenje za zdravstvene sustave. Mnogi pacijenti osjećaju trajnu nelagodu koja ometa rad, san i svakodnevne aktivnosti. Ipak, u većini slučajeva liječnici ne mogu utvrditi jasan strukturni uzrok, što otežava dugoročno liječenje.

Candida albicans povećava agresivnost melanoma
Izgleda da gljivica Candida albicans čini melanom, najsmrtonosniji tip raka kože, agresivnijim, sugeriraju rezultati nove studije. Naime, gljivica aktivira nekoliko signalnih puteva u stanicama melanoma i, kao rezultat toga, stvara okruženje koje pomaže u reprogramiranju angiogeneze i metabolizma; drugim riječima, okruženje koje stvara pogodne uvjete koji omogućuju malignim stanicama da dobiju više kisika i energije te se lakše šire u krv i druge organe.

Dojenje i trudnoća povezani s poboljšanom kognitivnom funkcijom u postmenopauzi
Prema rezultatima novog istraživanja, trudnoća i dojenje povezani su s boljim dugoročnim kognitivnim sposobnostima kod žena u postmenopauzi. Naime, studija je otkrila da povećanje kumulativnog vremena provedenog u trudnoći i vremena provedenog u dojenju korelira s boljom kognitivnom funkcijom, verbalnim pamćenjem i vizualnim pamćenjem kasnije u životu.
