In response to a request from Hvar's registered charity Dignitea, the EC has sent a full explanation of the regulations which should be applied to the proposed oil and gas drilling in the Adriatic.
John Ray, 17th-century botanist who coined words petal and pollen, was a tutor at Cambridge when he created his first garden
He coined the terms petal and pollen, helped to lay the foundations of modern biology and is widely regarded as the greatest English naturalist of the 17th century.
But it was while he was a young college tutor at Cambridge in the 1650s that the botanist John Ray – also known as “the father of natural history” – created his first known garden and began to systematically study plants for the first time.

Nottinghamshire tree, one of Europe’s oldest and largest, fails to produce leaves after being stressed by series of hot, dry summers
The Major oak, one of Europe’s oldest, largest and most celebrated ancient trees, has died.
The huge tree, which has grown in Sherwood Forest in Nottinghamshire, England, for at least 1,000 years, failed to produce any leaves this year, after becoming stressed by a series of hot, dry summers.

The Biodiversity Heritage Library is an invaluable online archive of historic texts on species living and lost supplied by the world’s leading museums and universities. Now its future is in doubt
Some go there to read about the wood that Victorian manufacturers used to make walking sticks. Others want to see an illustration of a Tasmanian tiger or marvel at the field diary of one of the first known botanists to explore the Antarctic.
Over the past 20 years, more than 64m pages have been made freely available through the Biodiversity Heritage Library (BHL) – a digital treasure trove for fans of the natural world. More than 680 museums, universities, libraries and scientific institutions from China, Singapore, Australia and New Zealand to Europe, Africa, Mexico, Canada and the US, have contributed to the library.

More than half of Ayetoro – a Christian utopia founded in the 1940s – has been lost to the ocean, and its remaining people are running out of options
In the early hours of 15 February 2019, the Atlantic Ocean came for Arowo Victoria’s livelihood. The 60-year-old retired midwife was asleep when neighbours began banging on her door, shouting that the sea had started covering buildings along the nearby coastline.
By the time she got to her small shop, she discovered that the Atlantic had already swept it away, destroying the business she had built with borrowed money after retirement.

We are told the natural world is ‘breaking down’. But forests don’t work like aeroplanes or human hearts
A version of this piece was originally published on Aeon as Why we need to think again about ecosystem failure
The Amazon rainforest, according to a 2021 study, is losing its capacity as a carbon sink and now emits more than it absorbs. In the tropics, marine scientists are reporting that coral reefs are in decline, threatening fish stocks. Equally concerning is research into the Atlantic Meridional Overturning Circulation (Amoc), a vast system of ocean currents that helps regulate the climate and is at risk of collapsing this century. The entire global ecosystem appears to be losing its ability to function.
We find this view in newspapers, magazines, technical reports and the journals of learned societies. But thinking about the environment in terms of its functions is also how many of us tend to understand the world. We may think that forests exist to produce oxygen, wetlands to filter water and bees to pollinate our crops.
Of special interest to humanity is the relationship of biodiversity to the variety of services provided by ecosystems and, in particular, to the stability of the flow of those services, such as the maintenance of the gaseous composition of the atmosphere, preservation of soils, recycling of nutrients and provision of food from the sea.

Warmer winters and springs are drying out wetlands and the birds are missing out on an abundance of insects to eat
When we think of spring migrant birds, it is easy to focus on songbirds such as warblers, flycatchers and swallows. Yet during late spring, many are waders – passing through Britain on their way north to breed in the high Arctic from their winter quarters in sub-Saharan Africa.
According to the British Trust for Ornithology’s regular migration blog, it has been a good year for waders: including more common species such as ringed and grey plovers, bar-tailed godwit, sanderling and knot.

Blackwater Estuary, Essex: Near a vast sweep of flats and creeks, one small pool has become a destination for both me and a parade of shore birds
I saw in this summer with the brief stays of Arctic-bound birds. Waders from the south came in such number and variety to my local patch near Tollesbury that for one week in May I went down to the marsh every dawn and dusk. I went to watch and feel the motion of it all at the turn of tide and time. Everything was change.
They kept coming, new species every day, ready to leave even as they arrived at this pool in the north-east corner of a field by the vast sweep of flats and creeks that give Essex more coastline than any other county in England.

Many small-scale landowners now include conservation measures alongside everyday farming. But progress is precarious, and the threat of guerrilla violence and poverty remain whichever candidate wins
Like most people settling in the area, Pablo Peña was seeking to escape violence and make a living from a patch of land when he moved to Guaviare in central Colombia. While his life has been strongly marked by conflict and deforestation, more than 30 years on he now focuses on community work and conservation.
Peña first visited Guaviare during his mandatory military service. Years later, in 1994, he settled down to farm in Guaviare’s Calamar, a town in a remote corner of the Amazon.

London Tree Ring project aims to create corridors of plant and animal life around the city to strengthen its biodiversity
Harry Ewing is heaping branches and foliage from the forest floor on to a dead hedge, reinforcing the protective circle around his newly planted trees in Hadley Wood, north London. He is in a glade created by a fallen oak that was previously overrun with thick bramble.
“I feel very happy – the trees are growing already. It’s really nice seeing it when it starts,” says Ewing.

Scientists are returning to a wartime solution that may be more sustainable than the traditional rubber tree
There is a global shortage of natural rubber and dandelions may be coming to the rescue. In the second world war there was such a severe shortage of rubber that the Allies used the Russian dandelion, Taraxacum koksaghyz, from Kazakhstan. Soviet scientists found the dandelion roots produced enough white milky latex to make natural rubber, but when the war ended producers returned to the traditional rubber tree, Hevea brasiliensis.
But the demand for rubber is now increasing, with rubber trees suffering from a fungal disease and the impacts of extreme weather caused by the climate crisis. So, scientists are looking again at using dandelions, with the added benefit that they grow in temperate climates, are a sustainable crop that do not need pesticides and lots of water, and don’t lead to the deforestation common in tropical rubber tree plantations.

Nova studija sugerira da bi jačanje prirodnih dnevnih ritmova tijela radi poboljšanja sna moglo pomoći mozgu da se oporavi nakon moždanog udara, što ukazuje na potencijalnu novu strategiju za poboljšanje uklanjanja otpada iz mozga i ishoda dugo nakon početne ozljede.
Vrsta bijelih krvnih stanica u imunološkom sustavu, poznata kao neutrofili, može smanjiti učinkovitost imunoterapije raka, tvrdi nova studija. Naime, rezultati pokazuju da signalna molekula u tumoru utječe na neutrofile, smanjujući učinak liječenja.
Dvostruko ciljana CAR T stanična terapija za rekurentni glioblastom (GBM), koja se primjenjuje izravno u cerebrospinalnu tekućinu (CSF), pokreće široki imunološki odgovor, s aktivacijom prirodnih stanica ubojica (NK) povezanom s boljim ishodima pacijenata i duljim ukupnim preživljavanjem, pokazuje nova studija.
Široko korišteni dodatak prehrani za zdravlje zglobova pod lupom je nakon što su znanstvenici povezali glukozamin s pogoršanim pamćenjem kod miševa s Alzheimerovom bolešću i lošijim ishodima u stvarnom svijetu kod osoba s demencijom.
Dulja izloženost ženskim hormonima tijekom života može povećati rizik od raka štitnjače kod žena, pokazuje nova studija. Istraživanje sugerira da reproduktivni i hormonalni čimbenici mogu biti uključeni u karcinogenezu štitnjače.
Japanski znanstvenici identificirali su prethodno neprepoznati mehanizam kojim strukturne promjene u malom mozgu utječu na socijalno ponašanje. Studija pokazuje da poremećaj specijaliziranih izvanstaničnih struktura koje okružuju cerebelarne neurone mijenja neuronsku aktivnost u moždanim krugovima uključenim u socijalno ponašanje. Ovo otkriće pruža novi uvid u neuronske mehanizme povezane s poremećajem iz autističnog spektra (PAS).
Kineski znanstvenici razvili su novu kombiniranu terapiju koja značajno poboljšava ishode liječenja i preživljavanje kod pacijenata s akutnom mijeloičnom leukemijom (AML) s mutacijama gena FLT3. Studija je otkrila da kombinirana upotreba inhibitora FLT3 kvizartiniba i inhibitora sinteze proteina omaketaksina, zajednički nazvana QUIZOM, učinkovito suzbija rast stanica raka i aktivira imunološki sustav pacijenta, postižući složenu stopu potpune remisije (CRc) od oko 83% uz smanjenje rizika od recidiva.
Smrtni slučajevi i dijagnoze mezotelioma i dalje su u porastu u SAD-u unatoč desetljećima regulacije azbesta i smanjene industrijske upotrebe. Studija je također otkrila malo poboljšanje u preživljavanju i pokazala da ovaj rak koji se može spriječiti i dalje nesrazmjerno pogađa žene i nekoliko država visokog rizika povezanih s brodogradnjom, rudarstvom i naslijeđenom izloženošću azbestu.
Dugo smatran uglavnom centrom za kretanje, mali mozak može igrati ključnu ulogu u kognitivnoj otpornosti, a novi MRI dokazi povezuju njegovu strukturu s oštrijim razmišljanjem u kasnijoj životnoj dobi. Naime, nedavno objavljena studija sugerira da mali mozak može doprinijeti kognitivnoj rezervi i pomoći u podršci kognitivnim performansama kod starijih populacija.
Smanjenje oštećenja srca tijekom srčanog udara (infarkt miokarda) ostaje jedan od glavnih izazova u kardiologiji, čak i kada se blokirana koronarna arterija pravovremeno ponovno otvori. Dio oštećenja miokarda i dalje je teško spriječiti unatoč napretku u reperfuzijskim terapijama. U potrazi za rješenjima za ograničavanje ovog oštećenja, studija koju je vodio IR Sant Pau, pokazuje da intravenska primjena atorvastatina tijekom samog ishemijskog događaja može poboljšati zaštitu srca u usporedbi s primjenom oralne udarne doze prije infarkta.
