Ze wegen nog geen 100 gram – de twee karabiners die ons, via het harnas, met de vleugel verbinden. Maar ze zijn cruciaal. Als er één in de lucht bezwijkt, volgt onvermijdelijk een rit aan je reserve. Bijzonder eigenlijk dat de karabiner het enige onderdeel van onze uitrusting is waarvoor géén officiële norm geldt. Tijd voor wat extra aandacht voor de karabiner.

"I'm telling that you don't need more than an EN-A wing in all your flying career!" Hannes Papesh, founder of Phi paragliders, is clearly a fan. In their range, Phi have eight different EN-A gliders.
Traditionally, the EN-B class got the biggest slice of the market. But this is changing, confirms designer Philipp Medicus from Nova: "EN-A has grown to be similar to B."

What is cloudbase? How does it feel to fly there? We answer these and other questions about where and how to fly with clouds in the ultimate cloudbase guide.

Naar aanleiding van het verschijnen van het boek 'Wanderbird Strategy' spraken we met Paul Guschlbauer over avontuur, de Red Bull X-Alps, Wanderbird en zijn nieuwe boek.

Jonathan A. Hutton is a very optimistic guy. Not in a glass-half-full sort of way, but really, thorougly, astonishingly optimistic. He has nose cancer, very rare and almost unheard of in 30-year olds like him. His memoirs, written up in his book Unflappable, tell his journey through treatment, cure, recurrence, repeat. And between all that he decides to learn paragliding.

Once again, Théo de Blic won the Acro World Tour 2025, securing his 5th solo AWT championship by winning all competitions and the Superfinal in Ölüdeniz (Turkey) in September.

Sebrand Warren eindigde (voor Nederland) als 21e — en als allerlaatste die de goal haalde — in de Red Bull X-Alps 2025. Zijn taaie eindsprint dwars door de buien leverde hem een dikke portie respect en applaus op. Een paar dagen later crashte hij, overmoedig door zijn prestaties, bij een toplanding in de Dolomieten en zit hij nu met een gebroken hiel verplicht op de bank. Tijd om terug te blikken.

On large, popular launches like Annecy it's easy to be convinced that you're not really part of the scene unless you're flying a pod harness. Open or sit harnesses are rare and if you fly one, inevitably someone will ask: "When are you going to get a pod?"
The reality is, there are many disciplines where an open harness is much more convenient. They are very popular and manufacturers tell us they sell more open harnesses than pods. There are so many types that there is an open harness for any flying style. And they are most definitely not only for beginners.

Aaron Durogati ended Chrigel Maurer's dominance of the RedBull X-Alps when he won the 1283km race in style in June. Bastienne Wentzel talked to him and the other final four about what was extraordinary and at times controversial, edition of the competition.
Bastienne Wentzel and Erwin Voogt contributed to reporting the race for Cross Country with photos, videos and interviews on social media, online as well as in print.

We talk about arc in the design of a paraglider, but what does that actually mean?

Naviter is a new race partner this year in the Red Bull X-Alps, which kicks off on 12 June 2025. It means they will be supplying all athletes with a flight instrument for tracking; the brand new Naviter Omni. But behind the scenes, Live Tracking is a lot more involved than just following the tracks of the athletes. Let's take a look. (Image: Naviter)

During the CIVL Plenary meeting in March, a proposal to allow performance equalisers in competitions was approved. The purpose is to reduce the inherent performance advantage of larger over smaller gliders by putting foam tubes on the lines of larger gliders to add drag. (Photo: Ozone)

Kanan
"When I was about six years old, we saw gliders on a family holiday in Panchgani. My dad asked them 'Will you take my daughter?". So I was strapped to the chute and in my memory the person behind me was just hanging from the two lines he was holding. Later I learned that the pilot sits in a harness too, and I thought, ah, that makes a lot more sense now!"
 
Josh
"I was around paragliding before I could walk or talk because of my dad Jocky Sanderson. I used to go tandem with him all the time. I initially learned paragliding at 13 and passed my exam at 14."

Finally, the day arrived that you can fly free. You just passed your exams and received the coveted pass to free flight: your pilot's license. Classic psychology tells us that you have graduated from 'unconscious incompetence' - when you started to fly you didn't know what you didn't know - to 'conscious incompetence'. You've become conscious of the fact that full competence in flying is still a long way away. Or as one instructor put it: you've learned to launch, land and not hit anything. But there is so much more to learn when it comes to flying. Where to start?

Porosity is one of the main properties that should be checked when your glider gets its periodic inspection. But we may be measuring it wrong, experts say. "We should be measuring flow, not time."

'Extreme botany' - Paramotors help conservationalists to protect ecosystems in Peru

Bij radiotherapie is foutloze identificatie van patiënten essentieel. Biometrische technologie maakt dit proces efficiënter en minder belastend. Hiermee wordt zowel de veiligheid als de patiëntenzorg verbeterd.

Ever stopped and looked at your karabiners in flight? Bastienne Wentzel investigates our most critical links.
They weigh less than 100 grams – the two karabiners that connect us, via our harness, to the glider. But each one of them is essential: failure of a karabiner in the air inevitably results in a reserve ride. Isn’t it strange that it’s the only part of our equipment that doesn’t have to meet a standard? They deserve a bit more TLC than we usually give them.

FLOW consortium to acquire a complete understanding of the cell's quality control network.

In the 2024 round of NWO Gravitation grants, the new consortium FLOW was awarded 23 million euros. Running from 2024 to 2034, FLOW will investigate the cellular factors that determine the fate of proteins throughout their life and learn how to influence that fate.

A chemically modified version of the antibiotic vancomycin is much more effective against MRSA and other Gram-positive bacteria than the original. Leiden university professor Nathaniel Martin and his group developed this guanidine modified lipoglycopeptide. They recently published their findings in the journal Science Translational Medicine.

A promising target for cancer therapeutics is the protease family of cathepsins. Researchers from the Swiss EPFL institute in collaboration with Dutch researchers from Radboudumc in Nijmegen succeeded in developing a highly specific, targeted way of inhibiting cathepsin activity. The results were published in May 2024 in the journal Nature Chemical Biology.

Postdoctoral project: Innate immune activation and sterile inflammation in microglia in human brain

Timo Oosenbrug is fascinated by immune receptors. "It is the first line of defense against viruses," he explains. "But what makes it even more interesting is what happens when these receptors keep firing all the time, causing sterile inflammation. The translation to this clinical condition is exciting."

Een nieuwe toepassing voor een bestaand geneesmiddel betekent dat nieuwe patiëntgroepen sneller, beter en vaak tegen lagere kosten behandeld kunnen worden. Investeringen in deze repurposed drugs zijn hard nodig. Daarbij kan octrooibescherming voor de nieuwe toepassing van het bestaande middel als vliegwiel fungeren.

“Dive, swoop, climb, soar…” Launched in a blaze of high-octane glory in 2022 parakites have now definitely come of age – attracting new pilots from disciplines like skydiving and kiting as well as paraglider pilots who want to go high-wind soaring at the coast. Bastienne Wentzel dials in...

It reads like a storybook. In 2021, fundamental research conducted at AMOLF formed the basis for the startup company Lumetallix. The company developed an easy to use
and affordable method for the detection of lead. Two years later, Lumetallix has sold thousands of test kits and now has collaborations with scientists, NGO's and even forensic experts.

Ron Heeren established fundamental research in the field of mass spectrometry and imaging of molecules at AMOLF. When fundamental physics gradually changed to applied medical and biological research, he moved his group to Maastricht University. His M4i institute's research, which enables the visualisation of molecules on and in cells to help clinicians improve their therapies, is renowned worldwide.

Remarkably, we don't know everything about the common cold virus HKU1, part of the coronavirus family. ICI researcher Joost Snijder (Utrecht University) and his team recently not only proved where and how HKU1 binds to the host cell, but also showed how this binding triggers a remarkable conformational change of the spike protein that is fundamental to how this virus enters the cell.

Early 2024, a remarkable publication appeared in Science in which Florian Winau at Harvard and his team describe how they discovered the function of a specific glycolipid called Gb3 found on B cells. From their results, they conclude that Gb3 has the potential to act as an adjuvant to improve vaccines against viral infections such as influenza.

PhD project: Targeting metabolism of the enteric glial cell in Parkinson’s disease

The enteric nervous system possibly plays a key role in Parkinson’s disease, making it a target for possible treatment. Anastasia Markidi at Utrecht University set studies the effects of bacterial metabolites on enteric glial cells.

PhD project: The role and effect of pathogenic amyloid proteins on neutrophil extracellular trap formation in the central nervous system

Enebie Ramos Cáceres is a jack of all trades: his PhD project comprises chemistry and immunology and he is doing all that on his own. He not only develops chemical probes to study key enzymes related to NETosis, relevant to Alzheimer's disease, but he also collects, prepares and studies human blood samples to test his probes.

Omics data sets are an increasingly important part of the research of wet-lab cell biologists and immunologists. But they are usually not equipped with enough bioinformatics or coding skills to be able to analyse these data sets. A first for PhD students in the ICI program, this spring they had the opportunity to participate in the online training "Omic data analysis and visualisation using R" which focuses precisely on these skills.

Op de startplek op de Babadağ hoog boven Ölüdeniz in Turkije loop ik Fatemeh tegen het lijf. Alweer, want een paar maanden eerder vertelde ze mij in Oostenrijk al over haar leven als paragliderpiloot in Iran maar toen was ze snel weer verdwenen, op weg naar andere vliegstekken in Europa. Deze keer laat ik haar niet gaan: ik wil meer weten van deze bijzondere dame. Dit is haar verhaal.

We krijgen niet wekelijks de kans om een directe vergelijking te maken tussen de ‘zware’ en de ‘lichte’ variant van hetzelfde scherm. De Vivo 2 en de LiVi van Airdesign die we afgelopen najaar uitgebreid mochten vliegen zijn helemaal identiek ontworpen, behalve dat de LiVi van lichtgewicht materialen is gemaakt. Het zijn beide EN-B schermen en ze hebben dezelfde vorm, afmeting en strekking. Wat merk je daarvan als piloot?

Where there is not even a hillock in sight a winch is the only way for paragliders to get airborne. All that is needed is a long open space roughly in the direction of the current wind. "Towing opens up a completely new range of flying areas," says Michael Gebert, a guide with the Swiss company Fly with Andy organising trips to fly from tow in Uruguay, Argentina, Brasil and the Balkans. "And it's a supersafe kind of flying," he adds.

Even knijpen en je weet of de avocado, perzik of tomaat rijp is. Zo doet een zachte robothand dat ook, bijvoorbeeld bij het geautomatiseerd oogsten. Maar tot nu toe had zo'n grijper sensoren nodig in zijn 'vingers' om te kunnen vaststellen of de vrucht rijp genoeg is. Shibo Zou en Bas Overvelde van AMOLF’s Soft Robotic Matter Group ontwikkelden een manier om van buitenaf, zonder ingebouwde sensoren de interactie van zachte robots met de omgeving te meten. De techniek is bovendien eenvoudig toepasbaar op allerlei bestaande zachte robots. Het onderzoek is op 15 januari 2024 gepubliceerd in het wetenschappelijke tijdschrift Nature Communications.

"I'm Fatemeh Eftekhari, one of the most well-known pilots in Iran. I'm one of the owners of Xagros Clouds air sports club in Iran. I am an active XC and competition pilot. My best flight so far was 241 km on a Skywalk Chili 5 in 2022. But my goal is to bring more ladies to the women's sport community."

As free flyers, we are exempt from quite a number of rules and regulations that apply to larger and motorised aircraft. A lot of our sport is self-regulated which makes it such a beautiful and free sport.
An example of this self-regulation we find in the certification process of paragliders and their maintenance. When you think all the norms, checks, inspections and repairs must comply with laws, rules and regulations, you could be disappointed. But the lack of a legal framework doesn't mean these things aren't important. It just means we can't hide behind a law but have to take responsibility ourselves.
