Analysis shows how heatwaves are making atmosphere thirstier, damaging water supplies, food production and power generation
Extreme heat supercharged by the climate crisis is sucking Europe dry in summer and intensifying the drought hitting the continent, a scientific analysis has found.
Record-breaking heatwaves meant the hot atmosphere strongly evaporated water from rivers, lakes, soils and plants – conditions made 80 times more likely by global heating in western Europe and 40 times more likely in eastern Europe, the study showed. The level of soil dryness in the west was made five times more likely by the pollution from fossil fuels in the west, and 11 times more likely in the east.

Scientists believe sunfish-smashing behaviour could be form of entertainment or to help younger whales feed
Orcas have been observed ramming into giant fish so hard that the prey explode, possibly as a form of gory entertainment.
On several occasions, orcas were observed to hold sunfish in their jaws while a second whale smashed into the target at high speed, causing it to break into thousands of pieces. Since the fish had already been killed, scientists suggested the behaviour may represent a form of play.

While many people in the UK recognise the need to preserve water, others are furious and planning to flout the ban in their area. The target of their anger? Failing water companies and frighteningly thirsty datacentres
‘Plants are like your babies,” says Harry. And accordingly, he argues, most people would do anything to keep them alive, including break the law. This is what he plans to do this week – defying a hosepipe ban in place across large parts of England, to ensure his shrubs maintain a steady pulse.
He may not be alone. On Tuesday, Thames Water became the latest company to ban hosepipes – a restriction that will affect more than 10 million people. Since mid-July, Welsh Water, Anglian Water, Affinity Water (serving Bedfordshire, Berkshire, Buckinghamshire, Hertfordshire and Surrey), Southern Water and Cambridge Water have all announced hosepipe bans. And earlier this week, South East Water extended its existing ban to cover an additional 1.5 million.

Shipping routes opened by climate change mean more industrial pollutants in the air
The gradual reduction in Arctic ice has started to open up new shipping routes, with marine traffic increasing by about 40% over the past 12 years. All these ships leave trails of pollutants in the air, which are already having a measurable climate effect.
Aerosol particles in engine exhaust act as nuclei for water droplets, promoting cloud formation. Like aircraft, ships may leave contrails behind them in the sky.

The Marches, Shropshire: Eyebrights are ancient herbs used to cure eye problems, but they also penetrate grass roots to siphon off water and nutrients
A sight for sore eyes. Eyebrights flower in the short turf of Old Racecourse Common as sunlight burns a hole through rowan trees to cast sunset colours on the grass. The eyebrights are annuals with tiny flowers, 4mm-11mm long with a violet vibe, a white corolla with purple marks and a central flash of yellow.
There are about 20 British eyebright species, some of which are endemic. Their genetic complexity makes them an arcane group of plants and a taxonomic puzzle to all but their most dedicated acolytes. “Life’s too short to key out [make a precise identification of] eyebrights,” one botanist told me.

Up to 25 tonnes of nurdles, the raw material for plastic manufacturing, have spread further than initially feared
Approximately a billion tiny plastic nurdles have entered the River Tyne after a “devastating spill”, with the pellets thought to have spread much further than first thought.
Nurdles, which are usually 1mm-5mm in size, act as the raw material to manufacture most plastic products.

A ‘reasonable worst-case scenario’ suggests need for large-scale movement of populations away from reshaped coast
Up to 13 million people in the UK face the long-term risk of coastal flooding due to the climate crisis, scientists have warned, with a “reasonable worst-case scenario” suggesting the need for the large-scale movement of populations away from a dramatically reshaped coast.
Even if today’s global pledges to cut carbon pollution are met, about 1.4 million more people will be exposed to coastal floods in 2200 and 1.7 million in 2300 due to the sea level rise driven by melting ice caps and warming oceans.

Miles Phillips greets me at the door of his house with a high five. His hair is spiked and a tiny, colourful parrot badge is pinned to his blazer collar. The two huge cameras being lugged behind me by two producers don’t faze him. This seven-year-old is a rock star.
Last week, Miles’ father, Joel Phillips, posted a “full band version” of his son’s song heralding the eastern rosella – a bright parrot native to south-eastern Australia.

Despite official claims that the São Francisco River project supplies 12m people, many of those who had to make way for its construction in 2007 still have no water at all
A concrete canal cutting through the Caatinga scrubland feeds a surface reservoir two and a half miles from Maria de Fátima Ferreira da Silva’s home in rural Brazil. The canal passes Sertânia and continues until it reaches Monteiro, the next town along, where it spills its precious cargo into the bed of the Paraíba River – a human-directed inflow into the seasonally dry waterway.
Such proximity to a reliable water source would usually be considered a blessing in the sertão, a vast outback in Brazil’s north-east known for its punishing droughts. But not for Ferreira, who was displaced nearly 20 years ago by the construction of the canal and now lives in a house without any water supply, despite the nearby reservoir.

Okultna infekcija virusom hepatitisa B (OBI) predstavlja značajan globalni zdravstveni izazov, poznato je da prolazi ispod radara standardnog virusnog probira dok neumoljivo potiče patogenezu hepatocelularnog karcinoma (HCC). Kritičan, ali slabo shvaćen faktor u tumorogenezi povezanoj s okultnom infekcijom virusom hepatitisa B je česta pojava mutacija u genomskoj regiji HBV pre-S.
Meta-analiza više studija u kojima je sudjelovalo gotovo 2 milijuna sudionika povezuje veći unos crvenog mesa s rizikom od raka gušterače, dok unos prerađenog mesa nije pokazao statistički značajnu povezanost.
Parkinsonova bolest je progresivni neurodegenerativni poremećaj uzrokovan gubitkom neurona koji proizvode dopamin, što dovodi do motoričkih simptoma poput tremora, ukočenosti, usporenog pokreta i oštećene ravnoteže, kao i kognitivnog pada. Iako trenutni tretmani pomažu u ublažavanju simptoma, ne mogu zaustaviti napredovanje bolesti.
Jedan preoperativni uzorak krvi može pomoći u poboljšanju predviđanja recidiva ili metastaza kod pacijenata s rakom debelog crijeva. Naime, nova studija je pokazala da, kako rak debelog crijeva napreduje, mreža odnosa među aminokiselinama u cirkulaciji (vrsta metaboličke mape) prolazi kroz sustavno preoblikovanje. Nadovezujući se na ovo otkriće, znanstvenici su razvili analitičku metodu koja je pokazala veću prediktivnu učinkovitost od modela samo s CEA i modela temeljenih isključivo na razinama pojedinačnih aminokiselina.
Žene koje imaju komplikacije u trudnoći poput gestacijskog dijabetesa, preeklampsije ili prijevremenog poroda imaju značajno povećan dugoročni rizik od razvoja periferne arterijske bolesti kasnije u životu, tvrdi nova studija.
Kronična, niska upala u tijelu povezana je s mnogim današnjim vodećim uzrocima bolesti i smrti, uključujući rak, bolesti srca, metaboličke poremećaje i neurodegenerativne bolesti. No, znanstvenici su se mučili razumjeti što uzrokuje upalu ili kako preokrenuti njezine učinke. No, nedavno su znanstvenici identificirali timus, mali organ iza prsne kosti koji igra središnju ulogu u razvoju imunološkog sustava, kao ključnog igrača u upali.
Nedavno objavljena studija izvijestila je o znatno smanjenim razinama endogenog litija u mozgu kod osoba s Alzheimerovom bolešću i blagim kognitivnim oštećenjem. Također je pokazala da smanjenje litija u prehrani ubrzava fosforilaciju tau proteina, taloženje amiloida β (Aβ), gubitak mijelina i sinapsi te kognitivni pad u mišjim modelima.
Specifične neravnoteže i poremećaji oralnog mikrobioma povezani su sa simptomatskim artritisom šake, pokazala je nova studija. Naime, pokazalo se, da mikrobno okruženje usta može utjecati na proces bolesti artritisa šake koji je povezan s boli, ukočenošću i smanjenom snagom stiska te može ozbiljno narušiti kvalitetu života. Oralni mikrobiom igra ulogu u sistemskoj upali i blisko interagira s crijevnim mikrobiomom koji je značajno povezan sa simptomatskim artritisom šake.
Crijevo potpuno obnavlja svoju unutarnju sluznicu svakih nekoliko dana što je jedan od najbržih procesa obnove u ljudskom tijelu. Znanstvenici su sada otkrili da ovaj izvanredan podvig prati skrivena mreža specijaliziranih mezenhimalnih potpornih stanica koje rade iza kulisa, otkrivajući neočekivanu razinu organizacije unutar crijeva i nudeći nove tragove koji bi na kraju mogli informirati pristupe ozljedama crijeva i upalnim bolestima crijeva.
Antimikrobna rezistencija kod djece raste globalno i pogoršat će se tijekom sljedećeg desetljeća, ugrožavajući učinkovitost antibiotika koji spašavaju živote, prema prvoj svjetskoj platformi za praćenje.
