Prof Tim Lang says country produces far less food than it needs to feed population and is particularly vulnerable
The British government should be stockpiling food, according to a leading expert on food policy, as it is not prepared for climate shocks or wars that could cause the population to starve.
Prof Tim Lang of City St George’s, University of London said the UK produced far less food than it needed to feed itself, and as a small island that relied on a few large companies to feed its giant population, it was particularly vulnerable to shocks.

Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño
Humanity is heating the planet faster than ever before, a study has found.
Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures.

First of the trusts, formed with 12 people in a Norfolk pub in 1926, buys swath of farmland to restore to nature
The place where Norton Wood once stood is now a vast field of decaying wheat stubble. The ancient wood was grubbed up during the second world war. No trace of it remains – on the surface, at least. This ghost in the landscape lives on only in the name of the local village: Wood Norton.
But trees will soon be bursting upwards again and the wood will regrow after Norfolk Wildlife Trust celebrated its 100th birthday by buying a swath of farmland to revive for nature.

Buxton, Derbyshire: Their ‘parents’ were planted 50 years ago by my wonderful late mother. Yet we all have a connection to these uplifting flowers
I wonder if nature has found a way to compensate us for the dreariest winter I can recall, because the snowdrops this year have been unbelievable. I’m seeing them everywhere – along road verges, on village greens, with vast white sheets across churchyards and especially in old gardens with driveways and mature trees around their margins.
I have a small snowdrop patch under our crab apple and while they’re modest in number, they are, in a way, more than flowers. My mother first planted those same bulbs (or their “parents”) in her garden, which is half a mile from here, in the 1970s. When she died a decade ago, I took them first to our old house and now to this property. I’d actually forgotten the last transfer: a scoop of both the bulbs and surrounding soil, a short car journey, then a hasty reinterment in a hole on this south-facing slope. Now here they all are, up in the light, sparkling and brimful of this seasonal moment, but also laden with memories of my wonderful Ma and her love of gardens. In a way, her snowdrops are now family.

New European Code Against Cancer calls on politicians to phase out use of fossil fuels in homes
Cutting air pollution should form part of government strategies to reduce cancer rates, the European Code Against Cancer has recommended.
The code previously focused on advice to help people to reduce the air pollution that they breathe. But, for the first time since its launch in 1987, it has given clear direction to governments.

Photographer Murdo MacLeod patrols the snow with members of the Scottish Avalanche Information Service, which has for several decades published a vital daily avalanche forecast for mountain areas
Scottish avalanches are back. More than 200 have been recorded this winter, against the previous year’s record low of 42. The worst season for fatalities was 2012-13 when eight people died, four of whom were buried in deep snow when an avalanche struck without warning while they descended Glen Coe’s Bidean nam Bian.
Fortunately, so far – despite one person being carried a distance down Ben Nevis and two people falling through cornices and triggering slips – there have not been any confirmed avalanche deaths, though one person is still missing on Ben Nevis. The search goes on in and around the sites of recent avalanches.
A mountain rescue team looks for a missing climber in Observatory Gully on the north face of Ben Nevis, an area where there has been a succession of avalanches

The 55 pilot whales, which had to be euthanised, had been following a female having a difficult birth, scientists believe
The mass stranding and death of 55 whales on the Isle of Lewis in 2023 was caused by the mammals’ loyalty to their pod, a report has concluded.
It had been thought that the unusually large incident on Tràigh Mhòr beach, Tolsta, could have been caused by trauma, disease or acoustic disturbance from military or industrially generated noise.

The country’s network of footpaths is growing – with hopes they will develop local economies and better preserve the environment
Follow the yellow footprints along Brazil’s newest long-distance trail, and they will take you through lush green forests and sandy shrubland, past sweeping vistas and bizarre rock formations, into grottos and rural communities.
Spanning 186km (115 miles) of paths once used by 19th-century merchants, the Caminhos da Ibiapaba is the first waymarked long-distance footpath in Brazil’s north-east region, adding to a growing network of hiking trails in the country.

Nova studija znanstvenika s Wake Forest University School of Medicine identificirala je obećavajuću strategiju za liječenje metastaza u mozgu, jedne od najizazovnijih i najsmrtonosnijih komplikacija raka pluća, melanoma i raka dojke. Naime, metastatska bolest mozga javlja se kod do 30% pacijenata s rakom pluća, melanomom i rakom dojke, a srednje vrijeme preživljavanja ostaje kraće od godinu dana.
Po definiciji, epizodno pamćenje je svjesni fenomen. Tragovi pamćenja koje reaktivira hipokampus i ponovno uspostavi u senzornim korteksima moraju ući u svjesnu svijest da bi se ponovno doživjeli i otvoreno prisjetili. No, sve više dokaza sugerira da se epizodno prisjećanje može dogoditi bez svjesne svijesti, što postavlja temeljno pitanje: kako sjećanja ulaze u svijest?
Kada netko doživi srčani udar (infarkt miokarda), srce se ozlijedi i preoptereti. Čak i kada pacijenti prežive početnu epizodu, srce često s vremenom slabi zbog ožiljaka i gubitka zdravog tkiva. Jedan od prirodnih odgovora tijela je oslobađanje hormona nazvanog ANP (atrijski natriuretski peptid), koji pomaže u smanjenju stresa na srce i može ograničiti dugoročnu štetu. Ali tijelo nažalost proizvodi samo malu količinu ovog hormona, nedovoljnu da napravi veliku razliku u oporavku srca.
Nova studija pruža snažne dokaze o mogućoj učinkovitosti terapija koje ciljaju i lizosome – ili čestice u stanicama koje pomažu u održavanju stanične stabilnosti i dostupnosti hranjivih tvari – i protein nazvan SREBP-1 koji povećava unos glukoze i pomaže tumorima da se odupru trenutnim terapijama koje inhibiraju lizosome, kod karcinoma pluća koji ne reagiraju na imunoterapiju.
Dijabetičke makrovaskularne komplikacije glavni su uzrok smrti i invaliditeta kod dijabetičara, a vaskularna kalcifikacija jedan je od ključnih patoloških mehanizama. Kalcifikacija u aterosklerotskom plaku može uzrokovati ukočenost i smanjenu podložnost vaskularne stijenke te izazvati rupturu aterosklerotskog plaka, što povećava rizik od akutnih kardiovaskularnih događaja.
Upalna osteoliza je stanje koje uključuje progresivno uništavanje koštanog tkiva i opaženo je kod mnogih poznatih skeletnih poremećaja, uključujući reumatoidni artritis, osteoporozu i kronični apikalni parodontitis. Ovo stanje je potaknuto imunosnom hiperaktivacijom, produženim imunološkim odgovorima i povećanim brojem osteoklastnih stanica koje razgrađuju kost, što zajedno uzrokuje upalu i slabljenje zahvaćenog koštanog tkiva.
Osobe koje koriste lijekove s antikolinergičkim učincima, uključujući određene antidepresive, lijekove za urinarnu inkontinenciju i uobičajene antihistaminike, imaju veći rizik od razvoja kardiovaskularnih bolesti, pokazuju rezultati nove studije.
Promjene na mozgu povezane s Alzheimerovom bolešću napredovale su do 20 puta brže kod žena koje su također imale abnormalne razine proteina alfa-sinukleina, inače povezanog s Parkinsonovom bolešću, tvrdi nova studija. Isti obrazac nije uočen kod muškaraca.
Sveobuhvatan pregled objavljen u stručnom medicinskom časopisu Lancet otkriva kako moderni lijekovi na bazi inkretina mijenjaju liječenje pretilosti i dijabetesa, ostvarujući snažan gubitak težine, a istovremeno štiteći srce, bubrege i metaboličko zdravlje. Pregled se izričito usredotočuje na agoniste receptora glukagonu sličnog peptida-1 (GLP-1), novije agoniste multireceptora i nove oralne terapije malih molekula.
