As a child, Dominique Bikaba, was displaced by a new national park in the DRC. Now he is helping to secure land for wildlife and Indigenous groups against the backdrop of ongoing fighting
Mist hangs low over the forested slopes of Kahuzi-Biega national park, where the canopy still shelters one of the last strongholds of the eastern lowland, or Grauer’s, gorilla. It is a landscape of immense biological wealth and equally immense political fragility. For 54-year-old Dominique Bikaba, it was once home.
His family was among those displaced when their ancestral land was incorporated into the park in the 1970s. The protected area, in the lowlands of South Kivu in the Democratic Republic of the Congo (DRC), harbours elephants and a remarkable range of wildlife, but it is best known as the principal home of the Grauer’s gorilla, the largest subspecies of primates, known to grow up to 250kg (39st) in weight. It is one of five great ape species found in the DRC’s vast forests, including mountain gorillas, which are also found in other parts of the Great Lakes region, such as Rwanda and Uganda.

Leaders say automated mowers’ blades threaten nocturnal animals as studies highlight risks to wildlife
German mayors have called for a nationwide ban on night-time use of robot lawnmowers to protect hedgehogs and other small nocturnal animals from being killed or maimed in the dark.
Recent studies have highlighted the threat lawnmower blades pose to wildlife active between dusk and dawn, prompting growing calls for regulation. Hedgehogs also tend to curl into a ball when threatened rather than running away, making them harder for a robot mower’s sensors to detect.

Concerns about coming wildfire risk, and temperatures also remain high on other side of Pacific where rare tropical cyclone has formed
After a historically warm winter across nine states in the US, the first month of meteorological spring again brought exceptionally high temperatures, with numerous states recording new all-time high temperatures in March. The remarkable intensity and longevity of the warmth have left much of the mountain snowpack, a crucial source of water for millions in the American west, at critically low levels.
Though precipitation totals tend to increase in spring, the low snowpack has raised concerns about a potentially severe wildfire season if conditions do not improve soon. And with further spells of abnormally warm, dry weather expected this week, the outlook is becoming increasingly worrying heading into the late spring and summer months.

Under Anne Hidalgo – mayor for 12 years until last week – the French capital added bike lanes, cut traffic and reclaimed public space, but not without resistance
When Corentin Roudaut moved to Paris 10 years ago, he was too scared to cycle. The IT developer had biked everywhere as a student in Rennes but felt overwhelmed by the bustling French capital. Cars were everywhere. Cyclists had almost no protection.
But once authorities carved out space for a segregated bike lane on Boulevard Voltaire near his home in the 11th arrondissement, Roudaut returned to the two-wheel commute and did not look back.

Tebay, Cumbria: A planned reintroduction of these apex predators has got us upland farmers worried. We’re still not convinced they won’t harm our flocks
The years seem to be coming around very quickly – this will be my ninth spring at this farm. As the days get longer and the grass begins to grow, my mind turns to lambing. We have a short growing season here, so we plan for lambing to start mid-April, hoping the grass will have started growing by then. The tiny Ouessant sheep, which have to lamb indoors due to predation, started lambing on April Fools’ Day.
Last year I put a large group of Ouessants outside to graze on the Roman fort when they were four days old, and they disappeared without a trace – 13 lambs lost. It wasn’t a fox or a badger, as we know what a predated carcass looks like, and it wasn’t the mink that had been killing hens, as that was leaving dead bodies.

Exclusive: research finds Jackdaw field would provide only about 2% of current demand, and Rosebank only 1%
Opening major new fields in the North Sea would make almost no difference to the UK’s reliance on gas imports, research has shown.
The Jackdaw field, one of the largest unexploited gasfields in the North Sea, would displace only 2% of the UK’s current imports of gas, which would leave the UK still almost entirely dependent on supplies from Norway and a few other sources.

The US has invoked national security to remove protections for the endangered cetacean, of which only about 50 are left
Since before modern humans existed Rice’s whales have been diving to the depths of the ocean to gorge on fat-rich fish while growing to leviathan proportions, their bodies spanning the length of a bus and weighing as much as as six elephants.
Unfortunately for these grand creatures, their only home became a patch of the Gulf of Mexico that the oil and gas industry, much later, became highly interested in for drilling. Only about 50 of these baleen whales still exist on Earth, surrounded by clanging aquatic highways of boats and shifting drilling infrastructure.

Before the 1970s global oil crisis, city planners in Copenhagen were considering removing bike lanes. Bicycles were considered outdated now car was king, and just 10% of locals were cycling regularly.
But as economic shock waves reverberated around the world, Denmark, which almost entirely relied on imported oil, took a dramatic U-turn, with citizens staging mass protests in the middle of highways demanding better cycling infrastructure.

Harsh weather is nothing new in Kenya but the country’s climate is showing clear signs of getting hotter and drier
The day is hot and dry but the soil underfoot is soft. “After four months of drought, we received the first rains yesterday,” says Maasai elder Abraham Kampalei. “All we can do now is pray that they continue.”
Kampalei has lived for more than 50 of his 70 years with his family and animals in Oldonyonyokie, a hamlet in southern Kenya’s Kajiado county. He has witnessed the slow decline of the pastures. “I came here because of the abundance of grass for my livestock to graze. Today, there is almost nothing left of it,” he says.

Stock runs low as oil crunch increases enthusiasm for electric vehicles

When a used vehicle rolls into a car yard, the usual trajectory for its price tag is down if it lingers too long.
That is the (almost) iron law of the secondhand market – until the oil crisis hit and dealers started raising asking prices for used electric vehicles.

Rizik od raka veći je za ljude koji se bore s autoimunim bolestima, ali opasnost se smanjuje nakon što počnu uzimati protuupalne lijekove, otkriva novo istraživanje. Naime, otkriveno je 32%-tno povećanje vjerojatnosti za rak u prvoj godini nakon dijagnoze autoimune bolesti poput lupusa, reumatoidnog artritisa ili psorijaze.
Čini se, da tretman stimulacije živaca nazvan TENS može smanjiti bol i umor kod fibromialgije, pokazuju rezultati nove studije. TENS je kratica za transkutanu električnu stimulaciju živaca.
Novo istraživanje osporava popularnu pretpostavku da narcisi postupno oštećuju svoje veze tijekom vremena. Inače, narcisi imaju dva različita načina održavanja svoje napuhane pozitivne samopercepcije. Mogu se hvaliti pokušavajući impresionirati druge (narcisoidno divljenje) ili mogu ponižavati druge ljude kako bi pokazali da su superiorniji od njih (narcisoidno rivalstvo).
Znanstvenici s Baylor College of Medicine otkrili su prethodno neprepoznati mehanizam kojim naslijeđene mutacije kalcijevih kanala ometaju rani razvoj mozga i predisponiraju djecu za epilepsiju i povezane kognitivne izazove. Smatra se, da ovi rezultati bacaju novo svjetlo na to kako suptilne genetske promjene mogu promijeniti moždane krugove mnogo prije početka napadaja.
Duktalni adenokarcinom gušterače najčešći je tip raka gušterače i ima nisku petogodišnju stopu preživljavanja. Počinje reverzibilnim stanjem koje se naziva acinarno-duktalna metaplazija, gdje stanice mogu zacijeliti nakon ozljede ili upale. Ako postoje mutacije koje uzrokuju rak, metaplazija može nastaviti napredovati prema raku.
Tumori uzrokovani mutacijama KRAS gena koje uzrokuju rak često su podložni feroptozi, vrsti stanične smrti koja se može iskoristiti za terapiju raka. S obzirom na to da više od 95% duktalnih adenokarcinoma gušterače sadrži takve mutacije, moglo bi se očekivati da će ovi tumori biti slično ranjivi. No, ipak, ti tumori ne pokazuju takvu ranjivost.
Nova studija znanstvenika s University of Texas MD Anderson Cancer Center pokazuje da specijalizirana vrsta zračenja s visokim dozama može značajno poboljšati ishode za pacijente s velikim tumorima žučnih vodova u jetri, poznatim kao intrahepatični kolangiokarcinom.
Ljudi mogu pretpostaviti da ako piju malo alkohola tijekom tjedna ili mjeseca, prekomjerno pijenje povremeno petkom ili subotom možda neće uzrokovati oštećenje jetre. No, novo istraživanje sugerira drugačije.
Novo istraživanje pokazuje da osobe koje žive s opstruktivnom apnejom u snu imaju 71% veći rizik od kardiovaskularnih događaja ili smrti od bilo kojeg uzroka u usporedbi s osobama koje nemaju sleep apneju.
Istraživanje provedeno u SAD-u pokazuje da tjelesna težina, san, pušenje i tjelesna aktivnost mogu biti važniji za hipertenziju od samog ukupnog rezultata prehrane, pri čemu se natrij i dalje ističe kao važan prehrambeni čimbenik.
