Off the coast of Western Australia, a humpback whale is “pirouetting”, sweeping its pectoral fins through the water, its massive jaw hanging wide open. Surrounded by companions, the animal isn’t lunging for a meal: rather, it is putting on a mysterious behavioural display.
This underwater ballet, captured on camera by an onlooker and shared online, is one of the clearest examples of a rarely documented phenomenon known as “gaping”.

Vitória Régia imagines rightwing Bolsonaro plot succeeded with US help – and highlights threats facing Indigenous peoples
The year is 2025 and far-right coup plotters have annihilated Brazil’s democracy, assassinating the president, closing the national congress and surrendering the Amazon rainforest and its untold riches to the United States.
“Ladies and gentlemen, welcome to the Amazon of America,” a thick-accented North American soldier tells a group of journalists being taken on a propaganda tour of an oil refinery in the newly annexed jungle realm. Nearby, a replica of the Statue of Liberty has been carved out of the wilderness to celebrate Washington’s tutelage over more than half of Brazil.

Allendale, Northumberland: Once again, wildlife has made a home here, in part because they feel safe
A big moon is cresting the Scots pine as I sit at an upstairs window looking down on to the garden. Awaiting the dusk emergence of a female tawny owl has become an evening ritual. After a day spent in the confines of a nest box in our sycamore tree, her departure shifts back by a few minutes every night. Completely silent, she drops towards the woodland border and skims the plants, each time on the same trajectory, a grey shadow in the gloaming.
Another movement on the path below catches my eye: a woodcock slinking along, using the box hedge to disguise her passage. If I hadn’t been watching for the owl I would never have known that she too is nesting somewhere in the garden’s thick leafiness. In July 2023, I wrote about a woodcock nesting in a flower border a few metres from the house, four chicks successfully hatching from four eggs. Last year, another attempt was disturbed by a cat captured on trailcam. This may be the same bird returned for a third time. Woodcocks are extremely secretive birds, their close proximity to a house very unusual.

East Midlands electric car club helps residents and cuts emissions – but the need for a volunteer-led scheme reflects a much wider problem
In the aftermath of the Covid pandemic Miriam Stoate, a regenerative farmer from rural Leicestershire, noticed that too many people in her small village in England’s East Midlands were struggling to get around.
Although there were plenty of cars parked in Tilton, too often she found some of the village’s residents did not have access to one when they really needed it.

Sarah Eberle hopes to inspire people to nurture where town and countryside meet and nature is need of protection
Stinging nettles, buttercups, broken crockery, fly-tipped flowers and a discarded gnome are not the usual hallmarks of an RHS Chelsea flower show garden.
But this year’s On the Edge garden by Sarah Eberle – the most decorated designer at Chelsea – is designed not to look like a garden at all, rather to transport its visitors to the liminal spaces on the outskirts of towns where the countryside begins and nature is in critical need of protection.

Emissions understated by factor of five in Essex plans for tech giant, while Greystoke’s Lincolnshire plans show similar error
Developers working for Google have significantly misstated how much carbon two proposed AI datacentres will contribute to the UK’s total emissions in planning documents reviewed by the Guardian.
The tech company wants to build two huge datacentres – one 52-hectare (130 acre) project in Thurrock and another at an airfield in North Weald, both in Essex. To do so, developers are required to submit planning documents calculating how much carbon these projects will emit as a proportion of the UK’s total carbon footprint.

London mayor talks up coalition-building, highlights his environmental record, and worries national Labour party is on the wrong track
When Sadiq Khan was first elected as mayor of London 10 years ago, Barack Obama was US president, the UK was still in the European Union and Leicester City had just been crowned the unlikely champions of the English Premier League.
In the intervening decade, Donald Trump has gone from reality TV star to two-time US president, the UK has had six different prime ministers, and Brexit has convulsed the country. London has been rocked by tragedies ranging from terror attacks to the Grenfell Tower fire.

Warming ocean waters are priming beaches and raw shellfish for Vibrio even as scientists are trying to stay one step ahead
Bailey Magers and Sunil Kumar cut strange figures on Pensacola Beach. Bags of disinfectant solution surrounded them on the white sand; their gloved hands juggled test tubes while layers of rubber and plastic shielded their skin from the elements. As the two organized their seawater samples on the popular Florida shoreline last August, an older woman wearing a swimsuit walked over to ask what they were doing.
“We’re just actively monitoring water quality,” they told her, but she pressed on.

Council’s plan will leave Federal Emergency Management Agency ill-equipped to respond to extreme weather events, experts say
Sweeping changes may be in store at the Federal Emergency Management Agency (Fema), the nation’s frontline emergency response coordinator, that experts warned could further erode US capacity to handle disasters as the risks of extreme weather fueled by the climate crisis continue to rise.
Fears about a fundamental overhaul of Fema’s form and function have been brewing since Donald Trump returned to the White House. After castigating the agency over claims that it was too expensive and “doesn’t get the job done”, Trump set to gutting Fema as an early priority for his second term.

Što se događa ako stanice raka izgube i mitohondrijsku opskrbu energijom i svoj glikolitički rezervni sustav? Ovo pitanje je ključno za novu studiju koju su proveli znanstvenici sa Northwestern Polytechnical University i suradničkih institucija.
Nedavno objavljena studija sugerira da bi široko korišteni lijek za astmu, formoterol, potencijalno mogao ponuditi sasvim drugačiji terapijski put te da bi se mogao koristiti za liječenje steatohepatitisa povezanog s metaboličkom disfunkcijom (MASH). Formoterol je agonist beta-2 adrenergičkih receptora koji se desetljećima propisuje za otvaranje dišnih putova kod stanja poput astme i kronične opstruktivne plućne bolesti (KOPB).
Desetljećima su liječnici i znanstvenici mislili da metformin, vodeći lijek za liječenje dijabetesa tipa 2 koji uzimaju milijuni ljudi diljem svijeta, uglavnom cilja jetru kako bi suzbio proizvodnju glukoze. No, nova studija je otkrila da se ovaj lijek umjesto toga prvenstveno fokusira na crijeva, djelujući tako da sprječava porast razine glukoze u krvi potičući iskorištavanje glukoze unutar stanica koje oblažu crijeva.
Prema rezultatima novog istraživanja, izgleda da hormoni povezani s muškim razvojem mogu igrati ključnu ulogu u ograničavanju rasta tumora mozga kod muškaraca. Naime, otkriveno je da gubitak androgenih hormona, poput testosterona, u predkliničkom modelu glioblastoma potiče rast tumora izazivanjem lokalne upale i poticanjem proizvodnje hormona stresa.
Nova studija sugerira da socijalna i profesionalna podrška mogu pomoći odraslima s dijabetesom tipa 2 da se pridržavaju vremenski ograničenog obrasca prehrane, prehrambene intervencije koja je pokazala obećavajuće rezultate u poboljšanju glikemijske kontrole i upravljanja tjelesnom težinom.
Nedavna studija temeljena na modelu miša sugerira da blokiranje TGF-β može poboljšati liječenje osteoporoze pomažući mirujućim osteoblastima na neaktivnim površinama kostiju da se vrate u aktivno stanje. Koristeći prostornu transkriptomiku, analizu pojedinačnih stanica i funkcionalne eksperimente, znanstvenici su identificirali TGF-β signalizaciju kao regulator aktivacije osteoblasta. U modelu miša s gubitkom kostiju, dvostruka inhibicija TGF-β i sklerostina povećala je koštanu masu učinkovitije od same inhibicije sklerostina, ističući obećavajuću strategiju kombiniranja.
Veći unos soje i mahunarki u prehrani povezan je s nižim rizikom od visokog krvnog tlaka (hipertenzija), otkriva nova analiza više studija. Optimalna dnevna količina može biti oko 170 g mahunarki, koje uključuju grašak, leću, slanutak i grah, te 60 do 80 g sojine hrane, primjerice tofu, sojino mlijeko, edamame, tempeh i miso.
Sindrom kratkog QT intervala je genetska bolest koja dovodi do iznenadne srčane smrti u mladoj dobi. Mutacije u genu SLC4A3, koji regulira izmjenu bikarbonata i klorida, nedavno su opisane kao potencijalni uzrok.
Američki znanstvenici identificirali su genetski sindrom u kojem neobično duge telomere - zaštitne kape na krajevima kromosoma - omogućuju imunološkim stanicama da ostanu biološki mlađe dulje od normalnog, predisponirajući pogođene osobe za limfom i druge vrste raka.
Imunoterapija raka temelji se na jednostavnoj, ali snažnoj ideji: imunološki sustav može prepoznati i uništiti stanice raka ako je pravilno aktiviran. Međutim, kod mnogih pacijenata taj je odgovor preslab ili prespor da bi bio učinkovit.
