Conservationists say cherished creatures such as whales, dolphins and seabirds are being killed in large numbers by fishing tackle
Thousands of Britain’s most charismatic and protected marine wildlife, including whales, porpoises, dolphins, seals and seabirds are being killed as “collateral damage” by fishing vessels every year, according to the first-ever analysis of bycatch data.
The analysis, by the Wildlife and Countryside Link, a coalition of voluntary conservation groups, reveals the devastating toll bycatch, the accidental capture and killing of non-target species by fishing vessels, is having on marine species.

Enfield council in north London took legal action against restaurant chain after outrage over damage to tree
The UK restaurant chain Toby Carvery has settled a legal dispute over taking a chainsaw to an ancient oak tree without permission, by agreeing to pay to restore a lost orchard.
The unauthorised partial felling of the 500-year-old oak next to a Toby Carvery car park in Whitewebbs Park, Enfield, north London, in April last year, prompted widespread public outrage and questions in parliament.

Crops and flowers rely on them for survival, but wild bees are declining – and crucial nutrients will go missing from our diets as a result
There are few ways in and out of Nepal’s Jumla district. The Karnali highway, considered one of the world’s most dangerous roads, provides the only land link, splicing through the Himalayas to connect Jumla’s terraced valleys to the rest of the country. As such, the 120,000 people that live there are almost entirely self-sufficient, with most of them eating and selling what they grow.
It’s a tenuous existence, plagued by food insecurity and malnutrition. In recent years, local beekeepers have bemoaned languishing hives and dwindling honey production, observing that roughly half of their bees seem to have vanished over the past decade. These concerns, however, ignore an even more insidious impact.

Some remains found in Diamantina fracture zone date back more than 5m years and reveal species and ecosystems unknown to science
The oldest, deepest and most extensive whale graveyard yet discovered has been found in the south-eastern Indian Ocean, with fossils dating back more than 5m years.
Whale falls – the term for dead whales that sink to the ocean floor – are not uncommon, but most have been found at depths of less than 4km (2.5 miles). By contrast, the newly discovered necropolis reaches depths of more than 7km, and extends hundreds of miles across the sea floor.

US energy secretary Chris Wright featured in seminars to judges when he was a fracking executive
As cities and states sue big oil for billions in damages over allegations that it covered up the dangers of its products, rightwing organizations are attempting to discredit the wave of litigation. They claim the lawyers behind it are teaming up with an environmentally focused legal education non-profit to bias federal judges against oil companies.
But it is actually fossil fuel-backed organizations that are attempting to sway the judiciary in their favor, one of those law firms is countering. Evidence of this includes judicial seminars hosted by one such group featuring pro-industry speakers such as the current energy secretary, Chris Wright, in his former occupation as a fracking executive.

Greenpeace calculates that wealthiest contribute nearly $1tn of damage a year with ownership-based emissions
Ultra-wealthy people zooming across the world on their private jets, lounging on yachts and conspicuous by their Instagrammable consumption are among the most easily identified individual culprits when it comes to the climate crisis – but new research argues that it is not just their heady lifestyles to blame, but also their bank accounts.
Through their ownership of companies and private financial and physical assets, from oil producers to property developments, the super-rich are responsible for an outsized slice of the greenhouse gases that are overheating the planet. The top 1% of people by wealth, through their shareholdings and investments, control about a quarter of global annual emissions in total.

The 700 projects include wind and solar farms, battery storage, gas and hydro plans
More than half the renewable energy projects needed to meet the government’s clean power targets by 2030 are now able to plug into the electricity grid after years of delay, according to the system operator.
The National Energy System Operator (Neso) has offered more than 700 clean energy projects in Great Britain a grid connection date since the start of the year, after a two-year process to unblock a bottleneck that threatened to delay projects into the 2030s.

As the US shuts its doors to most refugees, there’s little hope of a new system to help those forced from home by climate impacts
Millions of people around the world are having their lives upended by floods, storms and heatwaves worsened by the climate crisis. Those forced to flee their home countries, however, are finding that the door to the US is more firmly shut than ever.
Neither US nor international law recognizes environmental hazards, such as climate-related displacement, as a valid cause to claim asylum or gain entry through other migration pathways, despite the mounting toll of disasters caused by an overheating planet.

Pacoima is hemmed in by highways and heavy industry, and its residents are fighting pollution with hyperlocal air quality monitoring
Jose Luis Salas looks up at the ladder. “Are you ready?” he asks Shance Taylor, an environmental project manager who’s holding a white container, about the size of a shoebox, covered with wires and numbers.
Taylor nods and climbs up to reach the side of Salas’s tidy house in Pacoima, a neighborhood in Los Angeles’s north-east San Fernando valley. The curious box in their hands is known as Aeroqual sensor – part of a community air-quality monitoring program run by Pacoima Beautiful, a local environmental group.

The species is abundant within the protected archipelago but when they migrate outside the marine reserve to give birth they run the gauntlet of industrial fishing
The unmistakable fluted T-shape of a scalloped hammerhead shark slides by, followed by a diver holding his breath and a metal spear like an extra-long snooker cue. The spear hits the fish behind its dorsal fin and the 2-metre shark darts away, disgruntled but otherwise unharmed.
Carlos Robalino, a marine biologist from the Galápagos Islands, trained as a shark researcher in Mexico but is now back home and working as a junior researcher at the Charles Darwin Foundation. When we meet in March, he is one of the divers on the foundation’s research expedition to Darwin and Wolf, the most northerly islands in the Galápagos marine reserve.

Nova studija povezuje kronični zatvor (konstipacija) s većom vjerojatnošću depresije, ukazujući na puteve crijevo-mozak i potrebu za zajedničkom procjenom crijevnog i mentalnog zdravlja. Depresija je među najraširenijim, onesposobljavajućim mentalnim poremećajima u svijetu, značajno doprinoseći teretu bolesti i smrtnosti. Prema nedavnim globalnim procjenama, oko 350 milijuna ljudi ima depresiju. Kronični zatvor jedan je od najčešćih gastrointestinalnih poremećaja i uzrokuje trajnu nelagodu, remeti svakodnevne aktivnosti i psihološku dobrobit.
Rezultati nove studije pokazuju da povećanje histaminergičke signalizacije može izoštriti pronalaženje pamćenja, podržati adaptivno donošenje odluka i stabilizirati učenje iz negativnih iskustava, otkrivajući zanemarenu ulogu neurotransmitera u kognitivnim procesima.
Kineski znanstvenici razvili su mineralizirani DNK hidrogel koji kombinira imunološku regulaciju s održivom regeneracijom kostiju. Koristeći tetraedarske DNK nanostrukture i mineralizaciju kalcijevog fosfata, znanstvenici su stvorili skelet koji potiče aktivnost makrofaga pogodnu za zacjeljivanje, a istovremeno podržava matične stanice koje stvaraju kosti.
Prema rezultatima nove studije, rizik od moždanog udara se ne povećava jednako kod svih pacijentica s atrijskom fibrilacijom. Naime, studija sugerira da je ženski spol više poput modifikatora rizika, s povećanim rizikom od moždanog udara koji se prvenstveno opaža kod žena u dobi od 75 i više godina ili onih s većim opterećenjem drugim zdravstvenim stanjima.
Trenutne terapije za reumatoidni artritis oslanjaju se na trajnu imunosupresiju, a ne na obnovu imunološke tolerancije, pri čemu remisija bez lijekova ostaje rijetka. No, nedavna izvješća sugeriraju da bi terapija himernim antigenskim receptorom T (CAR-T) stanicama usmjerenim na CD19 mogla biti učinkovit pristup.
Pacijenti s refluksom kiseline, koji se javlja kada želučana kiselina prolazi u jednjak, dobro poznaju simptome: žgaravicu, podrigivanje, bol u prsima i probleme s gutanjem. Osim ovih tegoba, refluks kiseline također povećava rizik od raka jednjaka, koji ima petogodišnju stopu preživljavanja od oko 22%.
Rana primjena paracetamola može ubrzati zatvaranje otvorenog ductus arteriosusa kod izrazite nedonoščadi, tvrdi nova studija. Otvoreni ductus arteriosus (PDA) je često stanje kod nedonoščadi kod kojeg se fetalna krvna žila između aorte i plućne arterije ne zatvara normalno nakon rođenja. Stanje može povećati rizik od ozbiljnih bolesti i smrtnosti, posebno među najmanjom nedonoščadi.
Nova studija pokazuje potencijal novog pristupa liječenju anoreksije nervoze - poremećaja za koji su učinkoviti tretmani značajno ograničeni. Naime, pokazalo se, da je ketogena nutritivna intervencija - dijeta s visokim udjelom masti, niskim udjelom ugljikohidrata i umjerenim udjelom proteina - bila izvediva i sigurna za pacijente s anoreksijom nervoze s normaliziranom težinom i blago pothranjenom težinom. Sudionici studije su dobro podnijeli ketogenu intervenciju, s visokim stopama pridržavanja i bez značajnog gubitka težine tijekom cijelog programa.
Moždani udar je razorno stanje koje remeti pravilnu funkciju mozga. Nakon moždanog udara, mnogi pacijenti obično će osjetiti bol u udovima na strani tijela suprotnoj od moždane lezije. U rijetkim slučajevima, bol se razvija i na istoj strani kao i lezija, šireći se bilateralno na zrcalni način. To je fenomen poznat kao bilateralna bol ili bol zrcalne slike.
U nedavno objavljenoj studiji znanstvenici su istraživali može li istovremena inhibicija homologa Kirstenovog virusnog onkogena štakorskog sarkoma (KRAS), receptora epidermalnog faktora rasta (EGFR) i pretvarača signala i aktivatora transkripcije 3 (STAT3) izazvati trajnu regresiju karcinoma gušterače i spriječiti otpornost na liječenje.
