Staying at the ‘limit of friction’ is key to marrying speed and safety. Nick Carne reports.

Researchers from Yale and a medical company called Humacyte have published the results of a long term study that shows engineered blood vessels that are implanted into humans eventually evolved into living tissue. The vessels are known as bioengineered acellular human vessels (HAVs).

• Colliding black holes and neutron stars create ripples in spacetime, called gravitational waves. These were “heard” for the first time in September 2015.
• On Monday, a pair of gravitational-wave detectors called LIGO will turn back on after 6 months of downtime and upgrades.
• To boost its power, the experiment will now work with a sister machine in Italy called Virgo.
• Physicists expect the next period of searching for colliding black holes to last a year and be 40% more sensitive than before.

One of the most remarkable experiments in history — a pair of giant machines that listen for ripples in spacetime called gravitational waves — will wake up from a half-year nap on Monday. And it will be about 40% stronger than before.

That experiment is called the Laser Interferometer Gravitational-Wave Observatory (LIGO); it consists of two giant, L-shaped detectors that together solved a 100-year-old mystery posed by Albert Einstein.

A doomsday fungus known as Bd has condemned more species to extinction than any other pathogen.

Exceptionally well preserved 500m year old fossils show Cambrian seas were more diverse than scientists had thought.

Arthritis is usually painful. So is the surgery to fix it, at least in the immediate aftermath. So when a 66-year old woman at Raigmore Hospital in Inverness, Scotland, told doctors that her severely arthritic hand felt fine both before and after her operation, they were suspicious. The joint of her thumb was so severely deteriorated that she could hardly use it—how could that not hurt?

So they sent her to see teams specializing in pain genetics at University College London and the University of Oxford. Those researchers took DNA samples from both her and some of her family members and uncovered her secret: a tiny mutation in a newly-discovered gene. They recently published their results in the British Journal of Anaesthesia.

This minuscule deletion is inside something called a pseudogene, which is a partial copy of a fully functioning gene inserted elsewhere in the genome. Pseudogenes don’t always have a function—sometimes they’re just junk DNA—but some of them have residual functionality leftover from the original gene’s purpose.

Aeronautical engineer Edwin Van Ruymbeke has developed a remote-controlled insect ornithopter called MetaFly.

Capable of reaching a top speed of 18 km/h (11 mph) and a maximum range of 100 metres (328 ft), the wings are flapped using a mechanical coreless motor and an aluminum heat sink that is powered by a rechargeable lithium-polymer battery.

Weighing 10 grams (0.35 oz), MetaFly measures 19 cm long (7.5 in) with a 29-cm (11.4-in) wingspan. The patented wings are made from carbon fibre, liquid crystal polymer and oriented polypropylene.

The marriage of these two technologies can only mean something great is in store.

The turbineless design uses electroaerodynamic propulsion to fly and could herald the arrival of quieter, lower-emission aircraft.
