Appeal court finds in favour of anglers who said plans to clean up river were so vague as to be totally ineffectual
A group of anglers trying to restore the ecosystem of a river have seen off a challenge by the environment secretary, Steve Reed, who claimed that cleaning up the waterway was administratively unworkable.
Reed pursued an appeal against a group of anglers from North Yorkshire, who had won a legal case arguing that the government and the Environment Agency’s plans to clean up the Upper Costa Beck, a former trout stream devastated by sewage pollution and runoff, were so vague they were ineffectual.

Ban in place since 2021 has increased numbers of globally vulnerable pigeon species that is close to extinction in UK
Turtle doves will be allowed to be shot for sport again across Europe, as the EU lifts a ban on hunting that was credited with the species’ tentative recovery.
The EU will allow hunters to shoot 132,000 birds across Spain, France and Italy after the threatened bird enjoyed a population boom in western Europe because of a hunting ban that came into effect in 2021.

The hardy travellers can fly for 3,000 miles from the north-east US and Canada to roost in their millions in Mexico
Imagine your body was the weight of a raisin, supported by just a pair of flimsy, gossamer wings. Now imagine that you had to fly for 3,000 miles, avoiding storms, highways and predators, to ensure your species continued.
Could you do it? Unless you’re a monarch butterfly, fortunately you won’t have to face such a challenge.

More than half of Britain’s 59 native species are in long-term decline, UK Butterfly Monitoring Scheme finds
Last summer was the fifth worst in nearly half a century for butterflies in Britain, according to the biggest scientific survey of insect populations in the world.
For the first time since scientific recording began in 1976, more than half of Britain’s 59 native species are in long-term decline.

Experts are desperate to analyse rusty patched bumblebee nests for information that might help save them. But they are extremely hard to find – unless you’re a trained conservation canine
On a summer day in Somers, Wisconsin, Dave Giordano heard an unexpected buzzing in his back yard. What he found shocked him – a rusty patched bumblebee nest. The discovery was so rare it made the local news.
Once widespread across the midwest and eastern US, the rusty patched bumblebee has seen its population plunge by nearly 90%, prompting its listing in 2017 as the first federally endangered bumblebee in the US.

Government wants to spur economic growth and drive housebuilding but charities say nature should be priority
Wildlife groups have expressed alarm after ministers promised a radically “streamlined” approach to UK environmental regulation intended to drive economic growth and speed up new housing, as well as major projects such as airports.
While officials said the plans should boost nature conservation overall, the removal of what one called “bat by bat” decisions, a reference to the £100m bat shelter constructed for part of HS2, could water down individual protections.

If Peter Dutton needs to court the crossbench to form minority government after the election, he would risk putting his Coalition partner offside on climate and environment policy
If the Coalition wins the election, it will face a concerted push from its junior partner, the Nationals, to weaken and even abandon climate initiatives and promote coal as an interim measure in the Coalition’s nuclear power plan.
That would put Peter Dutton and the Liberals between a rock and a hard place should he seek to form a minority government, given that might require the support of environmentally minded crossbenchers.

Since February we’ve gone in search of the invertebrate of the year. Now it’s your chance to choose
Invertebrates – animals without spines – make up the vast majority of life on Earth. The Guardian’s invertebrate of the year contest celebrates the unsung heroes of the planet. Readers have nominated thousands of amazing animals, we’ve chosen a shortlist of 10, and now you can vote for your favourite.
1. The tongue-biting louse burrows in through a fish’s gills, clings to its tongue and eats what the fish eats.

A 19th-century zoologist found the ‘little salt dweller’, which could be a portal to the past – if only we could locate it again
Last February, with colleagues Gert and Philipp and my daughter Francesca, I made the long journey to an unremarkable city called Río Cuarto, east of the Argentinian Andes. We went in search of a worm of unusual distinction.
Why a worm? As humans, we naturally love the animals that are most familiar. But from a zoologist’s point of view, the vertebrates, from mammals and birds to frogs and fish, can be seen as variations on a single theme. We all have a head at one end (with skull, eyes and jaws); in the middle, a couple of pairs of limbs (a goldfish’s fins, or your arms and legs); and, holding all this together, a backbone ending in a tail.

Locals are feeling the impact of the more than 17,000 tonnes of uncollected rubbish in the city’s streets
“I’m afraid to open my front door, they’re everywhere,” said Mary Dore, eyeing the ground outside her house in Balsall Heath suspiciously. “They run out from under the cars when you get in, they’re going in the engines. They chewed through the cables in my son’s car, costing him god knows how much.
“There’s one street I can’t walk my dog because they come running out of the grass and the piles of rubbish. One time I screamed.”

Pretilost je povezana s povećanim rizikom od razvoja raka dojke, te većom vjerojatnošću da se rak proširi na druge organe – metastazira. No uzroci ove povezanosti još uvijek nisu dobro shvaćeni. Sada je nova studija pružila nove uvide otkrivši da prehrana bogata mastima aktivira mehanizme koji olakšavaju metastaze.
Vid je jedno od najvažnijih ljudskih osjetila, no ipak je više od 300 milijuna ljudi u svijetu u opasnosti od gubitka vida zbog raznih bolesti mrežnice. Iako je nedavni napredak u liječenju bolesti mrežnice uspješno usporio napredovanje bolesti, do sada nije razvijena učinkovita terapija za vraćanje već izgubljenog vida. No znanstvenici s KAIST-a uspješno su razvili novi lijek za vraćanje vida.
Ljudi s niskim razinama lipoproteinskog kolesterola niske gustoće (LDL-C) u krvi imaju manji rizik od demencije, uključujući niži rizik od demencije povezane s Alzheimerovom bolešću, pokazuje nova studija.
Linolna kiselina, omega-6 masna kiselina koja se nalazi u sjemenskim uljima kao što su sojino i ulje šafranike, te proizvodima životinjskog podrijetla, uključujući svinjetinu i jaja, posebno pojačava rast trostruko negativnog podtipa raka dojke koji se teško liječi, ukazuje nova studija.
Virulentni soj superbakterije otporne na antibiotike koja uzrokuje tešku bolest otkriven je u bolnici u Maleziji, što predstavlja značajan izazov globalnom javnom zdravstvu, otkriva nova studija.
Nova studija naglašava globalnu prevalenciju nedostatka vitamina D tijekom trudnoće i njegovu povezanost s komplikacijama kao što su gestacijski dijabetes, prijevremeni porod i intrauterino ograničenje rasta – unatoč dodacima prehrani i izlaganju suncu.
Lijek tirzepatid poboljšao je funkciju bubrega i kardiovaskularne ishode kod pacijenata s pretilošću i zatajenjem srca s očuvanom ejekcijskom frakcijom (HFpEF) u usporedbi s placebom nakon jedne godine, ukazuje nova studija.
Novorazvijeni krvni test za Alzheimerovu bolest ne samo da pomaže u dijagnozi neurodegenerativnog stanja, već također pokazuje koliko je napredovalo, sugeriraju rezultati nove studije.
Švedski znanstvenici identificirali su genetske varijante koje povećavaju rizik od ateroskleroze. Cilj je da ova nova saznanja omoguće ranije otkrivanje ateroskleroze i poboljšaju liječenje kardiovaskularnih bolesti poput srčanog udara (infarkt miokarda) i moždanog udara.
Osobe s visokim rizikom od ponovljenih srčanih događaja nakon perkutane koronarne intervencije (PCI), postupka otvaranja začepljenih arterija, imale su značajno bolje rezultate s klopidogrelom nego s acetilsalicilatnom kiselinom kao dugotrajnom antiagregacijskom terapijom, ukazuje nova studija.
