Temporary Tube


Surgeons are masterful at suturing – stitching tissues together – but even the most skilful doctor might find it difficult to sew together the ends of two tiny, slippery, squishy tubes – as is required when pairing together blood vessels during, say, an organ transplant or reconstructive surgery. To make such tasks easier and therefore faster researchers have developed a stent (pictured) that fits inside the ends of each tube offering a reinforced and more rigid structure to work with. Leaving such a stent inside the vessels is not ideal, however, so this new device is designed to magically melt away. The stent, which has so far been tested in pig arteries, can be 3D printed on demand and is fabricated from a type of sugar – sturdy enough for the surgeon to complete the procedure, but soluble enough to diffuse into the bloodstream in a matter of minutes.

A Swiss from Geneva prepares to a spaceflight

Feb. 11, 2019


Boris Otter has a crazy bet: to become the second Swiss to go into space. But as a tourist. This aviation enthusiast is continuing his cosmonaut training at the Star  City, near Moscow. He plans to realize his dream this year with a private company. It remains to raise 250,000 francs.

His career as a simulator pilot at Skyguide, Boris Otter is particularly fond. But his dream is much more ambitious. When he evokes it, his speed of speech accelerates: “I am convinced that 2019 will be the year of space tourism thanks to companies like Virgin Galactic. I pursued a cosmonaut training by going to Moscow’s Star City for the second time to acquire the necessary knowledge and skills that would enable me to become the second Swiss in space after Claude Nicollier. “


At the age of 49, this inhabitant of Grand-Lancy demonstrated his unwavering determination to carry out his spatial ambitions: “The strong accelerations, the weightlessness, the wearing of the Sokol space suit, the rotary chair, the spatial food , the simulation of spacewalk in the hydrolab (swimming pool containing a model of a part of the International Space Station), all these formations are accessible in Russia and I was able to follow them or am on the verge of make.”


Financing in progress


Only obstacle to realize this spatial dream, to find the financings. Because a flight in space, when possible – with Virgin Galactic for example – should cost around 250,000 francs.

A substantial amount that he hopes to gather in the coming months. “I have several ideas. The first would be to be sponsored by one or more luxury watch brands. The steps are underway. Otherwise, I am importing space food from Russia to introduce these atypical meals to the people of Geneva. But it requires many permissions, you have to be patient to achieve your goals. “


Iron health


Another essential condition of a journey in space, to be in good health. On this side, the Genevois is no problem: “A double medical visit is performed upon arrival at the Cité des Etoiles. The doctors in charge of allowing you, or not, to carry out your training program are the same ones that allow cosmonauts to take off for space. They control your temperature, blood pressure, heart rate, toenails, back and do not negotiate too long if your pressure is too high, it is eliminatory for certain activities! Fortunately, I passed these tests without a hitch. “


It remains to collect a quarter of a million francs and wait for the first flights of space tourists …


Reaction of Claude Nicollier, the only Swiss to have gone into space


“I would not call it a trip into space”

“I am in favor of space tourism in general, it is a way of offering the possibility to non-professional astronauts to experience some of the extraordinary sensations of spaceflight”, explains the astrophysicist Vaudois Claude Nicollier, the only Swiss to have gone into space. Who continues: “That said, space flights for tourists planned in the coming years are not real trips into space. The mission profile is to climb almost vertically with a launcher or a space plane, just to exceed 100 km altitude with about four minutes of weightlessness, then down to Earth. It is rather a crossing of the very high atmosphere and a short excursion beyond the border of space! The climb will be impressive, the view will be beautiful with black sky in daylight and clear perception of the rotundity of the Earth, and the four minutes of weightlessness will be a magnificent sensory discovery, but rather brief … “


It remains to be seen whether the passengers of such flights will become astronauts? “I do not know, and I’m sure there will be heated discussions on this subject,” says Claude Nicollier. Before saying: “For me, and with all due respect for those who will try the adventure, they will not really be astronauts in the true sense, but rather what is designated in English under the name of participating spaceflight. “


“To know how to remain humble”


What would you recommend to them? “Have fun, bring back a lot of photos (not just selfies), help promote the value of human spaceflight and share their emotions with loved ones, the public and with children! It is also important to remain humble after such an experience. The very great cosmonauts-astronauts like Yuri Gagarin and Neil Armstrong were impressive in their humility. “


Boris Otter: bio express


An avid aeronautic enthusiast, Boris Otter began his journey to space by trying his weightless flight in Russia in 2016. A first experience of which he returned enthusiastically. It was at this moment that this 49-year-old resident of Grand-Lancy decided to go even further by enrolling in a cosmonaut training at the Cité des Etoiles north-east of Moscow in the city of shchyolkovo. A course which ended at the beginning of January of this year.


Editor note:


Indeed, Claude Nicollier rightly, we must make a difference between an astronaut (a professional who has done a professional formation and not just selected training) and a paying passenger, more than just parabolic flights and no orbital flights, an astronaut or cosmonaut (or taikonauts for the Chinese) must have made an orbital flight (minimum a complete orbit of the Earth) to claim this title.

New Data: Ultima Thule Surprisingly Flat
Illustration Credit: NASA, JHU’s APL, SwRI


Explanation: Ultima Thule is not the object humanity thought that it was last month. When the robotic New Horizons spacecraft zoomed past the distant asteroid Ultima Thule (officially 2014 MU69) in early January, early images showed two circular lobes that when most simply extrapolated to 3D were thought to be, roughly, spheres. However, analyses of newly beamed-back images – including many taken soon after closest approach – shows eclipsed stars re-appearing sooner than expected. The only explanation possible is that this 30-km long Kuiper belt object has a different 3D shape than believed only a few weeks ago. Specifically, as shown in the featured illustration, it now appears that the larger lobe – Ultima – is more similar to a fluffy pancake than a sphere, while the smaller lobe – Thule – resembles a dented walnut. The remaining uncertainty in the outlines are shown by the dashed blue lines. The new shape information indicates that gravity – which contracts more massive bodies into spheres – played perhaps less of a role in contouring the lobes of Ultima Thule than previously thought. The New Horizons spacecraft continued on to Ultima Thule after passing Pluto in mid-2015. New data and images are still being received.

The Serpent Stone, Senhouse Roman Museum, Maryport, Lake District, 9.2.19.


One of the most striking carved stones in the collection, the Serpent Stone is likely a Roman dedication stone inspired by the fertility symbol of the serpent and the phallic shape to guard against the Mediterranean notion of the ‘evil eye’. Discovered in 1880, the face also had two serpents over the forehead but they soon broke off.

Venus Unveiled

Explanation: What does Venus look like beneath its thick clouds? These clouds keep the planet’s surface hidden from even the powerful telescopic eyes of Earth-bound astronomers. In the early 1990s, though, using imaging radar, NASA’s Venus-orbiting Magellan spacecraft was able to lift the veil from the face of Venus and produced spectacular high resolution images of the planet’s surface. Colors used in this computer generated picture of Magellan radar data are based on color images from the surface of Venus transmitted by the Soviet Venera 13 and 14 landers. The bright area running roughly across the middle represents the largest highland region of Venus known as Aphrodite Terra. Venus, on the left, is about the same size as our Earth, shown to the right for comparison.

Allergy and Microbes


With the prevalence of food allergies on the rise, understanding what contributes to them is of growing importance. Now researchers have begun to get a handle on the possible biological underpinnings, showing that cow’s milk allergy – not to be confused with lactose intolerance – is influenced by the bacteria (shown here in red) present in the gut (blue and green). Cow’s milk allergy commonly affects infants and often manifests as blood in the stool (much to the horror of parents). Scientists have discovered that the gut bacteria of babies with such allergies differ to those of healthy infants. Furthermore, while gut bacteria from healthy human babies could, when transferred to mice with an equivalent allergy, protect the animals from developing allergic reactions, bacteria from babies with cow’s milk allergies could not. The findings suggest that rather than being passive passengers, bugs in the gut actively shape the host’s immune system.
