CO2 in air hit new high last year, with scientists concerned natural land and ocean carbon sinks are weakening
Levels of carbon dioxide in the atmosphere soared by a record amount in 2024 to hit another high, UN data shows, deepening the climate crisis that is already taking lives and livelihoods across the world.
Scientists are worried that the natural land and ocean “sinks” that remove CO2 from the air are weakening as a result of global heating, which could form a vicious circle and drive temperatures up even faster.

Climate advisers warn that current plans to protect against extreme weather are inadequate
Britain must prepare for global heating far in excess of the level scientists have pegged as the limit of safety, the government’s climate advisers have warned, as current plans to protect against extreme weather are inadequate.
Heatwaves will occur in at least four of every five years in England by 2050, and time spent in drought will double. The number of days of peak wildfire conditions in July will nearly treble for the UK, while floods will increase in frequency throughout the year, with some peak river flows increasing by 40%.

American officials have threatened supporters of measure to reduce emissions with tariffs and other retaliatory action
Donald Trump’s government is putting intense pressure on vulnerable countries to vote against measures that would force shipping companies to pay for their carbon emissions.
US officials have written to countries that support the measure and besieged them with phone calls threatening to impose tariffs, withdraw visa rights and take other retaliatory action.

The Advertising Standards Authority agrees with River Action that the food safety body’s 2023 advert misled the public
The UK’s advertising watchdog has upheld a complaint that Britain’s biggest farm assurance scheme misled the public in a TV ad about its environmental standards.
The Red Tractor scheme, used by leading supermarkets including Tesco, Asda and Morrisons to assure customers their food meets high standards for welfare, environment, traceability and safety,is the biggest and perhaps best known assurance system in Britain.

Hampstead, London: Spring has the dawn chorus, autumn has “vismig”, the changing of the guard of millions of birds – an early start for me, then, to try and glimpse this remarkable phenomenon
I’ve monitored the autumn forecast. Mushrooms and conkers, good, occasional blackberries; acorns crunching underfoot, moderate; spiders’ webs and cosy jumpers intensifying; severe crumble-making, veering west.
And migrating birds. Storm Amy has passed, and with air pressure rising, there’s the whiff of a seasonal treat: visible migration – “vismig” for short. They travel in their millions – summer visitors outgoing southwards, winter arrivals incoming from the north. Swallows, pipits, thrushes, finches and more. A remarkable population shift to mark changing seasons. Many fly by night, but some are diurnal, and at the right time and place, you might see a slice of this unrivalled phenomenon. Spring has its dawn chorus; vismig is autumn’s gift.

Allegations related to flood control projects have sparked widespread anger and protests in the Philippines
Philippine health worker Christina Padora waded through July’s waist-high flood water to check on vaccines and vital medications stored in the village clinic, something she had regularly done during previous typhoons.
But this time she didn’t make it. Taking hold of a metal pole that she failed to see was connected to a live wire, the 49-year-old was fatally electrocuted in the water.

Only two female northern white rhinos are left – but neither can carry a pregnancy. So a surrogate was used. Tragically, the foetus didn’t reach full term
This photograph captures a moment of fragile hope: the world’s first IVF rhino pregnancy, a tiny foetus that reignited optimism among scientists fighting to save the northern white rhino from extinction. There are only two female northern white rhinos left on the planet – Najin and her daughter Fatu. Neither can carry a pregnancy due to health complications. The last male died in 2018 and that makes the species functionally extinct.
For the past 15 years, the BioRescue Project – an international consortium dedicated to saving the species – has been collecting and preserving sperm from deceased males. Using this genetic material and egg cells from Fatu, they’ve created 38 embryos. It may sound like a lot, but it’s not. Since Najin and Fatu cannot carry a pregnancy, surrogate mothers are essential and it was decided to use southern white rhinos, a less endangered subspecies. The team also needed to prove that their technique would work with southern white rhino embryos before transferring any of the northern white rhino embryos into a surrogate.
After 13 attempts to transfer an embryo they achieved the first viable IVF pregnancy in a southern white rhino. The foetus in this image is the result after transfer. Tragically, the pregnancy didn’t reach full term (16-18 months), as the surrogate mother died from a bacterial infection at 70 days. But the pregnancy demonstrated that the technique is viable – a critical milestone.

Garden getting you down? Tempted to just pave or concrete over the whole thing and put your feet up? There are more enjoyable and eco-friendly alternatives, from miniature meadows to giant borders
When faced with a muddy swamp, or a lawn that needs mowing (again), the most nihilistic among us may dream of concreting over the whole garden – and some turn that dream into reality. A recent report by the Horticultural Trades Association (HTA), which represents garden centres and suppliers, has warned that within the next five years, nearly a quarter of UK householders plan to pave or deck over at least part of their garden, and of those, nearly a third plan to cover more than half of the area. The HTA estimates this could mean a loss of about 8% of the UK’s total private green space, or 409 sq km.
“Paving over gardens with impermeable surfaces has and will continue to undermine urban resilience,” says Prof Alistair Griffiths, the director of science and collections at the Royal Horticultural Society (RHS). Water can’t get through concrete, asphalt and paving, which contributes to surface flooding and overwhelms the sewer system, leading to pollution runoff. Loss of vegetation also contributes to global heating. “We’ve got these increased extremes of heat and if you lose green space, you lose that cooling effect,” he adds. Then there’s the loss of biodiversity that comes from paving over green space – not to mention the impact of a dead, grey landscape on people’s mental health. One RHS study showed that people who nurtured a couple of containers of flowers and a small tree in an urban street lowered their stress hormones as much as if they’d attended eight weekly mindfulness sessions.

HUP-Koordinacija veledrogerija upozorila je na alarmantnu razinu i kontinuirani rast duga državnih bolnica prema veledrogerijama koji je s krajem rujna dosegnuo 800 milijuna eura, od čega je više od 600 milijuna eura dospjelih i neplaćenih obveza. Zabrinjavajuća je i dinamika rasta duga od 40 milijuna eura na mjesečnoj razini koja je neodrživa i zahtijeva hitno rješenje.
Prema rezultatima novog istraživanja, izgleda da dva estrogena - estradiol i estriol - mogu pomoći u ublažavanju simptoma progresivne multiple skleroze. Inače, kod progresivnog oblika multiple skleroze, simptomi se kontinuirano pogoršavaju ili nakon razdoblja remisije.
Mehanizmi mozga za popravak ozljeda uzrokovanih traumom ili degenerativnim bolestima još nisu detaljno poznati. Sada nova studija opisuje novu strategiju temeljenu na terapiji matičnim stanicama koja bi mogla poboljšati regeneraciju neurona i neuroplastičnost kada je ovaj vitalni organ oštećen. Rezultati otkrivaju da bi upotreba neurotrofičnog faktora izvedenog iz mozga (BDNF), u kombinaciji s terapijama stanicama temeljenim na matičnim stanicama, mogla pomoći u liječenju neurodegenerativnih bolesti ili ozljeda mozga.
Novo istraživanje sugerira da ketogena dijeta s visokim udjelom masti i niskim udjelom ugljikohidrata može pomoći u zaštiti mladih životinja od trajnih posljedica stresa doživljenog prije rođenja.
Gotovo svaka peta medicinska sestra u primarnoj zdravstvenoj zaštiti (PZZ) razmišljala je o odlasku u inozemstvo, a svaka četvrta ne bi ponovno odabrala svoje zanimanje, pokazuje istraživanje Hrvatske komore medicinskih sestara (HKMS) provedeno u prosincu 2024..
Rezultati nove studije pokazali su, da su kognitivne sposobnosti onih koji su prestali pušiti značajno manje pale nego kod pušača u šest godina nakon prestanka pušenja. Za verbalnu tečnost, stopa pada se otprilike prepolovila, dok se za pamćenje usporila za 20%.
Osobe u dobi od 60 i više godina koje su pretjerano pospane tijekom dana mogu imati više problema s pamćenjem i razmišljanjem nakon operacije, sugerira nova studija. Dnevna pospanost je simptom nedostatka sna koji pogađa do 20% odraslih i može povećati rizik od perioperativnih neurokognitivnih poremećaja (PNP).
Neplodnost pogađa otprilike jedan od šest parova, a muški faktori čine otprilike polovicu svih slučajeva - često zato što spermiji nisu pokretljivi. Nova studija koju su proveli japanski znanstvenici otkrila je temeljnu promjenu u spermi, pružajući dublje razumijevanje regulacije pokretljivosti spermija. Naime, otkriće osi TMEM217-SLC9C1-sAC nudi novu metu za dijagnosticiranje neobjašnjivih slučajeva muške neplodnosti.
Nova studija otkriva da ljudi koji preskaču doručak imaju veću vjerojatnost razvoja metaboličkog sindroma i njegovih ključnih komponenti: masnoće na trbuhu, visokog krvnog tlaka, visokog šećera u krvi i visokog kolesterola, što naglašava važnost jednostavnog jutarnjeg obroka za dugoročno zdravlje.
Kako broj slučajeva upalne bolesti crijeva (IBD) raste diljem svijeta, znanstvenici otkrivaju kako zapadne prehrambene navike destabiliziraju crijevno-imunološki sustav i zašto prilagođena prehrana može biti ključ za zaustavljanje upale prije nego što započne.
