Frontrunner Zack Polanski has dismissed claims of a ‘hostile takeover’ but contest has been unusually fractious
The Green party will name its next leader on Tuesday after a fiercely fought leadership contest that has exposed tensions over tone, strategy and the party’s ambitions on the national stage.
The frontrunner, Zack Polanski, has pitched himself as a bold communicator able to turn rising support into a mass movement. He is facing the joint candidates Ellie Chowns and Adrian Ramsay, two impactful Green MPs elected last year who are seen as offering a steadier, more targeted route to growth.

Conservationists hope that in 15 years species will no longer be at risk of extinction in Mexico – but challenges remain
In 2010, Gerardo Ceballos and a group of other researchers set out to answer a burning question: how many jaguars were there in Mexico? They knew there weren’t many. Hunting, loss of habitat, conflict with cattle ranchers and other issues had pushed the population to the brink of extinction.
Ceballos and his team from the National Alliance for Jaguar Conservation (ANCJ) thought there were maybe 1,000 jaguars across the country. They decided to carry out the country’s first census of the animal to find out exactly how many there were. They found 4,100.

Most of these little-known but already endangered fish have never been seen alive in their natural habitat, but are under threat from bottom trawling and deep-sea mining
Three years ago I was running a research project from a bottom trawler off Namibia about deep-sea sharks – all of which live under enormous water pressure, close to the seafloor and are rarely seen by humans.
These sharks were being brought up in the trawler’s nets. By the time they were brought to the surface, they had experienced such a dramatic change in pressure that they had undergone barotrauma, so they were internally damaged and unlikely to survive.

Cadair Idris, Gwynedd: The heather is dominant on the slopes today, as I embark on a steep climb in the heavy heat
As I head over the top of the pass from Corris, the great mass of Cadair Idris emerges against a leaden sky. The steep crags that stand above the thickly wooded slopes are coloured a deep purple by the flowering heather, but the usual vibrancy is subdued by the flat, almost sullen, light.
Getting off the bus at Minffordd, I wander up the avenue of chestnut trees that form such an impressive welcome to the mountain. A drift of dry, discoloured leaves stands at the edge of the path, something I wouldn’t expect to see for another month or so, suggesting that the trees are suffering water-stress after the dry summer.

Heavy rain, lightning and tornadoes lash swaths of continent, with France, Italy and Slovenia among worst hit
Severe storms linked to a deep upper air trough formed from the ex-hurricane Erin lashed parts of western and southern Europe last week.
Italy was hit by severe rainfall on Thursday that caused flooding in the Lombardy region. The commune of Busto Arsizio was badly affected, with more than 100mm of rain and frequent lightning.

Unspecified number of vessels due to depart Barcelona on Sunday, with dozens more expected to leave other Mediterranean ports on 4 September
A flotilla carrying humanitarian aid and activists, including Swedish climate campaigner Greta Thunberg, is due to leave from Barcelona on Sunday to try to “break the illegal siege of Gaza”, organisers said.
The vessels will set off from the Spanish port city to “open a humanitarian corridor and end the ongoing genocide of the Palestinian people”, said the Global Sumud Flotilla.

In the last continent to remain untouched by the virus, hopes are being pinned on immunisation as migration season approaches
It is easy to imagine how it could happen. A petrel, flying east from the Indian Ocean at the end of the Austral winter, makes landfall at New Zealand’s southern Codfish Island/Whenua Hou. Tired from its long journey, the petrel seeks refuge in the burrow of a green kākāpō: a critically endangered flightless species that is the world’s fattest parrot.
If the seabird intrudes when the kākāpō is primed to breed, the male parrot may attempt to mate with the smaller petrel, accidentally smothering it in the process.

Across the world, women at the heart of their communities are leading the struggle to protect their culture, land and way of life
“We, the daughters of mother earth … have come together to collectively decide what we can do to bring about a world which we would like our children and our children’s children to live in,” so states the Beijing Declaration of Indigenous Women.
Adopted in 1995, the document outlined the oppression of women around the world and demanded governments recognise “the social, cultural, economic, and religious rights of the Indigenous peoples in their constitutions and legal systems”.

Ditching sanitary towels and tampons has made my period much less stressful. Crucially, it’s better for the environment too
I was 18 when I tried a menstrual cup for the first time. I was studying at the University of Edinburgh and Scotland had just become the first country in the world to make period products free to those who need them. The university health service was offering menstrual cups alongside the usual sanitary pads and tampons. I picked one up out of curiosity and because I just couldn’t resist a freebie.
I was used to spending £10 to £15 a month on period products, more if I was caught short and had to do a panicked dash to an overpriced off-licence. As an eco-conscious teenager I already bought non-applicator tampons but often wore a security sanitary liner underneath. It was an attempt to keep the endless worry of heavy periods at bay: will I leak, run out of supplies, or find a clean loo in time? Even so, I leaked more often than I cared to admit.

Široko korišteni lijek za dijabetes metformin mijenja razinu metala u krvi kod ljudi, ukazuje nova studija. Metformin je najčešće propisivani lijek za dijabetes u svijetu. Osim što snižava razinu šećera u krvi, poznato je i da ima širok raspon korisnih nuspojava, poput djelovanja protiv tumora, upala i ateroskleroze. Međutim, iako se koristi već više od 60 godina, njegov mehanizam djelovanja još uvijek nije jasan, što ometa razvoj još boljih lijekova protiv ovih stanja.
Bakterijska DNK iz usne šupljine, dišnih putova, crijeva i kože otkrivena je u aterosklerotskim plakovima, što upućuje na ulogu u kroničnoj upali povezanoj s aterosklerozom. Kronične bakterijske infekcije često stvaraju biofilmove otporne na antibiotike i imunološki sustav, što u odgovarajućim uvjetima dovodi do nastanka nove generacije virulentnih bakterija.
Rezultati nove studije pokazali su da ultraprerađena hrana ne samo da potiče debljanje i pogoršava razinu kolesterola, već utječe i na reproduktivne hormone i zdravlje sperme.
Beta blokatori - lijekovi koji se obično propisuju za niz srčanih stanja, uključujući srčane udare - ne pružaju kliničku korist pacijentima koji su imali nekomplicirani srčani udar (infarkt miokarda) s očuvanom funkcijom srca, sugeriraju rezultati REBOOT kliničkog ispitivanja. Inače, beta blokatori su standardni tretman za ove pacijente već 40 godina.
Kronična bubrežna bolest (CKD) glavni je zdravstveni problem diljem svijeta. Mnogim pacijentima na kraju je potrebna redovita dijaliza kako bi izbjegli zatajenje bubrega i ostali živi. Unatoč težini stanja, trenutno nema dostupnih lijekova koji poboljšavaju funkciju bubrega.
Hormonska kontracepcija je životna činjenica za milijune žena. Samo u SAD-u, više od 60 milijuna žena reproduktivne dobi koristilo je kontracepciju najčešće kako bi spriječile trudnoću, ali i za upravljanje stanjima poput endometrioze, sindroma policističnih jajnika i neredovitih ciklusa.
Bolesti bubrega pogađaju gotovo 700 milijuna ljudi diljem svijeta i rastući su uzrok smrtnosti i troškova zdravstvene skrbi. Samo kronična bolest bubrega (CKD) doprinosi više od 1,2 milijuna smrtnih slučajeva godišnje, s akutnom ozljedom bubrega (AKI) kao ključnim prekursorom.
Sindrom policističnih jajnika (PCOS) jedan je od najčešćih poremećaja koji pogađaju do 15% žena reproduktivne dobi u cijelom svijetu. Vodeći je uzrok anovulacijske neplodnosti i glavni faktor rizika za dijabetes tipa 2. Povišene razine testosterona su stalna hormonska abnormalnost kod žena sa sindromom policističnih jajnika.
Nova studija pokazuje da obični lijekovi protiv bolova, kada se uzimaju uz antibiotike, mogu izazvati opasne mutacije u bakterijama, otkrivajući kako polifarmacija kod starijih osoba može tiho promovirati globalnu krizu antimikrobne rezistencije.
Mikrobi unutar kancerogenih tumora mogu utjecati na širenje bolesti i učinkovitost liječenja. Te uloge čine ih privlačnim metama za nove terapije i nude načine za bolje predviđanje rizika. Alati temeljeni na tumorskoj mikrobioti mogli bi pomoći u identificiranju pacijenata s visokim rizikom i osoba najosjetljivijih na metastaze, a moguće bi se mogli koristiti i za poboljšanje alata za prognozu, tvrde kineski znanstvenici.
