More than 100,000 African seeds put in Svalbard vault for safekeeping
More than 100,000 seeds from across Africa have been deposited in the Svalbard Global Seed Vault, the world's repository for specimens intended to preserve crop diversity in the event of disaster.
Among the latest additions are seeds critical to building climate resilience, such as the tree Faidherbia albida, which turns nitrogen into ammonia and nitrates, and Cordia africana, the Sudan teak, a tree renowned for its strength and durability.
The seeds, from 177 different species, were delivered to the Norwegian vault on Tuesday by Dr Éliane Ubalijoro, the chief executive of the Center for International Forestry Research and World Agroforestry (Cifor-Icraf).
'For me, seeds are about hope,' Ubalijoro said. 'They're about moving beyond survival, particularly when you come from places that have gone through really difficult times. When I think of my country of Rwanda and what happened in 1994, seed banks were critical when it came to rebuilding after the genocide.'
Ubalijoro said countries that had experienced disaster and conflict could emerge as leaders in the fight against climate breakdown.
'We understand the urgency,' she said. 'We understand what it is to go through deep despair and having to rebuild completely. It also creates personal stories which people who haven't gone through such collective traumas can relate to. It's this idea of having a seed bank for the planet. How we care collectively for each other, how we care for the biodiversity of our food systems is critical.
'We have areas in Asia, Africa and Latin America that go from drought to wetlands, so there's a huge opportunity to learn from the knowledge of Indigenous peoples to create the resilience we need.'
It was also important to nurture environments where native trees could thrive, Ubalijoro said. 'If you plant trees in the wrong area, you risk creating what are called ecological deserts where local pollinators don't recognise or feed on those trees, and that actually decreases biodiversity.'
She said recognising the significance of women's roles in agriculture was also important. 'In many countries in Africa, 60% of women or more participate in agriculture. We must ensure the biodiversity that is needed to protect these 'women's crops', and make sure they are prioritised,' she said.
'I'm a mother. I viscerally feel the need to preserve our planet's biodiversity. It's about creating the possibility of a greener, more resilient future together, and making sure the landscapes we cherish today continue to thrive for generations to come.'

Faidherbia albida
An indigenous African tree that is known for its fast growth, Faidherbia albida can reach up to 30 metres tall. It is a much sought-after nitrogen-fixing tree, meaning it converts nitrogen found in the atmosphere into a form that can be used by plants, improving soil health and productivity and helping ecosystems adapt to change.
Acacia polyacantha
Also known as white thorn, Acacia polyacantha is a flowering tree that can grow to up to 25 metres in height. It has several medicinal uses including for treating snake bites and livestock infections such as salmonella. Its leaves also serve as fodder for cattle.
Adansonia digitata
The African baobab is the most widespread tree species of the adansonia species group. It is nutrient-rich and high in fibre, potassium, magnesium, iron, calcium, zinc and vitamin C. It also has anti-inflammatory properties and its leaves are used to treat kidney and bladder diseases, asthma, diarrhoea and insect bites.
Sesbania sesbanSesbania sesban, also known as Egyptian riverhemp, has nitrogen fixation properties, meaning it can help with soil fertility and stabilisation. It is also a food source, with its leaves being used to feed livestock and its seeds fermented into tempeh. Its leaves have antiinflammatory, antioxidant and antiviral properties.
Cordia africana
A mid-sized, white-flowered evergreen tree, the Sudan teak is a valuable timber species native to Africa and part of the borage family.

Butterflywatch: UV torches aid monitoring of rare and elusive species
Nature lovers have been enjoying using UV torches to discover the vivid fluorescent colours of plants and animals at night for a few years now. Now lepidopterists have realised that UV torches provide a highly effective new way to find and count rare and elusive butterflies. Butterfly Conservation is working with Berks, Bucks & Oxon Wildlife Trust (BBOWT) to train volunteers to hunt for glow-in-the-dark caterpillars. Elusive tree-dwelling butterflies such as the rare brown hairstreak are particularly difficult to monitor in the wild. The butterfly lives in treetops and is difficult to see as an adult, and its caterpillars are superbly camouflaged. Brown hairstreak colonies are typically monitored by painstakingly hunting for its microscopic eggs, which are found on blackthorn twigs in midwinter. But now there's an easier way: shining a UV torch on hedgerows at night can reveal glowing caterpillars. UV torches make the luminous larvae gleam as if they are producing their own light – an effect known as photoluminescence. The well-camouflaged chrysalis of the purple emperor is virtually impossible to find in daylight and yet it also glows under UV light – delighting enthusiasts who search for these charismatic insects.

Get all the week's environment news - the good, the bad and the essential after newsletter promotion Steven Lofting, a conservation manager for Butterfly Conservation, says surveying via UV torches could be 'a gamechanger' and significantly improve our understanding of rare and hard-to-find butterflies' distribution, abundance and ecology.

Amid federal research cuts, some Antarctic tourist cruises are sponsoring scientists
During Antarctica's warm season, the sleek Norwegian passenger ship known as the MS Fridtjof Nansen departs regularly from Argentina for its journey south across the turbulent Drake Passage, down to the Antarctic Peninsula. The cruise carries wealthy adventurers, bucket listers and, increasingly, polar scientists looking to gather data as public funding for Antarctic research vanishes under the Trump administration. The National Science Foundation is one of the largest funders of scientific research in the world, with an annual budget of roughly $9 billion that supports the bulk of U.S. Antarctic research. Over the last few months, the Trump administration has ordered deep cuts to the agency, leaving scientists to wonder how they'll study everything from melting glaciers and ice sheets to the impact of pollution from power plants and wildfires. On Thursday, Sethuraman Panchanathan, the director of the National Science Foundation, resigned after the White House directed him to slash the agency's budget and staff by more than half, according to exclusive reporting from Science. Panchanathan's resignation follows an earlier order from Elon Musk's Department of Government Efficiency to freeze funds for all new research grants at the National Science Foundation, and last week's announcement that DOGE will be terminating over $200 million in 'wasteful' research grants awarded by the agency. Some experts are concerned that the Trump administration's ongoing cuts to the National Science Foundation may signal the end for American research in Antarctica. James Barnes, the co-founder of the Antarctic and Southern Ocean Coalition, an international alliance for environmental nongovernmental organizations focusing on Antarctic conservation and research, says that the National Science Foundation has become an 'evil word' among many in the Trump administration. 'It's tragic to me having the National Science Foundation's budget cut,' he said in an interview with NBC News. 'For what reason? It's not good for us on lots of levels, because there's lots to be learned in Antarctica.' President Donald Trump's directives specifically targeting Antarctic research include high-profile firings of several National Science Foundation staffers working on Antarctic projects and cuts to essential construction funding for McMurdo Station, the biggest U.S. research base on the continent. Research operations based in Antarctica had already been dwindling for several years — decades of robust field work were disrupted and never recovered from Covid-19 restrictions. Now, research on the world's southernmost continent is facing several years under Trump's slash-and-burn policies. But aboard the MS Fridtjof Nansen and its sister ship, the MS Roald Amundsen, polar scientists have reliable funding for their research. HX Expeditions, which operates the two Antarctic ships, hosts researchers from institutions like Western Washington University; the University of California, Santa Cruz; and the National Snow and Ice Data Center. Their room and board is covered by ticket purchases from tourists sailing to Antarctica for their once-in-a-lifetime trips. 'We would not be able to support the research that we are supporting if we did not have paying customers that would allow our ships to go down south,' Verena Meraldi, chief scientist of HX Expeditions, said. 'It's not easy [to get there]. There are not many flights going down here and there are fewer and fewer research vessels.' The tourists traveling with HX Expeditions are part of the exploding ecotourism industry, which centers on experiencing nature while supporting local conservation. The number of visitors to Antarctica has increased from around 8,000 every year in the 1990s to more than 120,000 annually, according to the latest data from the International Association of Antarctica Tour Operators. By 2035, the ecotourism market is projected to grow to over $550 billion. On its late March expedition to the Antarctic Peninsula, the MS Fridtjof Nansen was home to more than 400 ecotourists and several researchers, including Freya Alldred, a doctoral student from Durham University in England who says that without this cruise, it's unlikely she would have been able to get to Antarctica. Alldred traveled with sterilized bags to collect samples of seaweed growing in Antarctic waters and snow algae, which blooms on the continent's vast expanse of snow. She is studying how climate change affects the carbon content of these Antarctic species, and the cruise offered a unique opportunity to collect new samples. 'We've not been to anywhere with a research base,' Alldred said. 'If instead, I'd gone to the British Antarctic base, I could only sample within my area. Whereas here, we've been to five different sites across the peninsula that have potentially not been studied before.' The boat housed scientists and ecotourists in close quarters, giving scientists the rare opportunity to explain their work directly to nonscientists through interactive sessions in the onboard lab. For 10 days, eager passengers attended lectures from resident researchers, ate with them in the ship's restaurants and shared their first steps on the vast polar desert that is Antarctica. 'To share these experiences with people and then explain why we do the research, what types of questions we're answering with it, and for them to see it firsthand is incredible,' said Chloe Lew, a researcher working with California Ocean Alliance to capture the impact of tourist boats on humpback whales in the Antarctic. 'It kind of fires me up at my passion for the work.'

Norway launches scheme to lure top researchers away from US universities
Norway has launched a new scheme to lure top international researchers amid growing pressure on academic freedom in the US under the Trump administration. Following in the footsteps of multiple institutions across Europe, the Research Council of Norway on Wednesday launched a 100m kroner (£7.2m) fund to make it easier to recruit researchers from other countries. The initiative is open to researchers from around the world, but it was expanded and accelerated after the Trump administration announced substantial cuts last month. Norway's announcement comes before a visit to the White House by the Norwegian prime minister, Jonas Gahr Støre, and his finance minister, the former Nato secretary-general Jens Stoltenberg. Subjects on the agenda are expected to include security, defence, Ukraine, tariffs and trade. The Nordic country's minister for research and higher education, Sigrun Aasland, said: 'It is important for Norway to be proactive in a demanding situation for academic freedom. We can make a difference for outstanding researchers and important knowledge, and we want to do that as quickly as possible.' Aasland added: 'Academic freedom is under pressure in the US, and it is an unpredictable position for many researchers in what has been the world's leading knowledge nation for many decades.' The research council said it would put out a call for proposals next month including in the areas of climate, health, energy and artificial intelligence. The scheme is planned to take place over several years, with 100m kroner set aside for 2026. Mari Sundli Tveit, the chief executive of the research council, told broadcaster NRK: 'This is particularly relevant to the situation in the US. Academic freedom is under pressure and funding is being cut.' Other countries to take similar action include France, where nearly 300 academics have applied to Aix-Marseille University's offer to take US-based researchers and the former French president François Hollande has called for the creation of a 'scientific refugee' status for compromised academics. The Belgian university, Vrije Universiteit Brussel, has also opened up new postdoctoral positions targeted at Americans and the Netherlands has said it plans to launch a fund to attract researchers there.
