Capsule is the first US-made, designed-for-crew spacecraft to dock in eight years
SpaceX‘s new crew capsule has arrived at the International Space Station, completing its second milestone in just over a day.
No one was onboard the Dragon capsule that launched on Saturday on its first test flight, only an dummy.

Astronauts could be flying again from US soil as early as this summer after the flawless launch of SpaceX’s privately built Crew Dragon capsule opened “a new era in American excellence”, according to the head of the space agency Nasa.

A pair of twins have stunned researchers after it emerged that they are neither identical nor fraternal – but something in between.
The team say the boy and girl, now four years old, are the second case of semi-identical twins ever recorded, and the first to be spotted while the mother was pregnant.

A new object has been discovered in the distant reaches of our solar system and given the name FarFarOut, according to a prominent astronomer.
At 140 times further away from the sun than our own planet is, the newly identified body – if its discovery is confirmed – will become the furthest known object in our solar system.

The wooden blinds that lie crumpled in Peter Gasson’s laboratory in Kew Gardens are chipped and forlorn-looking. Their manufacturers had claimed they were made of pine but customs officers were wary. And their suspicions were well-founded. Gasson, Kew’s research leader on wood and timber, found the blinds were not made of pine but ramin.
“All ramin trees, which grow in south-east Asia, are endangered and trade in their wood is illegal,” said Gasson. “On this occasion, we got lucky and stopped people profiting from this trade.”

A Japanese spacecraft has successfully touched down on a speeding asteroid 300 million kilometres from the Earth as it attempts an audacious manoeuvre to collect samples and bring them back for scientists to study.
The Hayabusa 2 probe touched down on the asteroid Ryugu at around 11:30pm GMT on Thursday. Data from the probe showed changes in speed and direction, indicating it had reached the asteroid’s surface, according to officials from the Japan Aerospace Exploration Agency (JAXA).

As long as an adult thumb, with jaws like a stag beetle and four times larger than a honeybee, Wallace’s giant bee is not exactly inconspicuous.
But after going missing, feared extinct, for 38 years, the world’s largest bee has been rediscovered on the Indonesian islands of the North Moluccas.

The mystery of how the zebra got its stripes might have been solved: researchers say the pattern appears to confuse flies, discouraging them from touching down for a quick bite.
The study, published in the journal Plos One, involved horses, zebras, and horses dressed as zebras. The team said the research not only supported previous work suggesting stripes might act as an insect deterrent, but helped unpick why, revealing the patterns only produced an effect when the flies got close.

The US government has warned that older people should not be paying to have their veins filled with the blood of young people, in a blow for what was becoming a fad anti-aging treatment.
In a statement on Tuesday the Food and Drug Administration (FDA) said infusions of plasma from young donors into older clients “should not be assumed to be safe or effective”, and said it was “concerned that some patients are being preyed upon by unscrupulous actors” charging thousands of dollars for transfusions.

Scientists are developing a radical form of gene therapy that could cure a devastating medical disorder by mending mutations in the brains of foetuses in the womb.
The treatment, which has never been attempted before, would involve doctors injecting the feotus’s brain with a harmless virus that infects the neurons and delivers a suite of molecules that correct the genetic faults.

Scientists studying the 2015 Zika outbreak in Brazil have discovered that people previously exposed to dengue may have been protected from the virus.
Three-quarters of the inhabitants of a favela in the country’s north-east caught the mosquito-borne Zika virus during the epidemic. The outbreak left more than 3,000 babies across Brazil with microcephaly, a birth defect caused by mothers catching the virus during pregnancy.

An experimental drug that bolsters ailing brain cells has raised hopes of a treatment for memory loss, poor decision making and other mental impairments that often strike in old age.
The drug could be taken as a daily pill by over-55s if clinical trials, which are expected to start within two years, show that the medicine is safe and effective at preventing memory lapses.

Nasa declared the 15-year mission of the veteran Mars rover Opportunity finally over on Wednesday, crediting the robot as having “transformed our understanding of our planet”.
The golf buggy-sized vehicle last made contact with Earth eight months ago, after being caught in a global dust storm.

It’s hard to imagine anything less like a lunar landscape than the medieval glories of Lichfield Cathedral. But this summer, an artist will transform its magnificent tiled floor into a representation of the moon’s surface to mark half a century since Neil Armstrong took “one small step for [a] man and one giant leap for mankind”.
The three-spired cathedral in Staffordshire has commissioned the art installation as part of its annual summer show, which this year is called Space, God, the Universe and Everything. Peter Walker, the cathedral’s artist-in-residence, will also use light and sound installations inspired by space and the planets.

A collection of short wiggly structures discovered in ancient rocks could be the earliest fossilised traces of organisms able to move themselves, scientists say.
If scientists are correct, the 2.1bn-year-old structures point to an earlier origin than generally thought for eukaryotes – cells with a membrane-bound nucleus and which make up plants, animals and fungi – previouslybelieved to have first emerged about 1.8bn years ago. It also pushes back the earliest evidence of self-propelled movement of eukaryotes by 1.5bn years – scooping the title from far younger multicellular lifeforms – and would be the first clear signs of motility for any type of organism.

Stonehenge, with the possible exception of Big Ben, is Britain’s most recognisable monument. As a symbol of the nation’s antiquity, it is our Parthenon, our pyramids – although, admittedly, less impressive. Neil MacGregor, the former director of the British Museum, recalls that when he took a group of Egyptian archaeologists to see it, they were baffled by our national devotion to the stones, which, compared to the refined surfaces of the pyramids, seemed to them like something hastily thrown up over a weekend.
Unlike those other monuments, though, Stonehenge is more or less a complete mystery. Nobody knows for sure why, or by whom, this vast arrangement of boulders was erected on Wiltshire’s downlands, in the south of England, about 5,000 years ago. Into this void have rushed myriad theories, from the academically sober to the blatantly fantastic. Over the centuries, its construction has been confidently credited to giants, wizards, Phoenicians, Mycenaeans, Romans, Saxons, Danes and aliens. (According to one medieval theory, Merlin had it transported from Ireland to serve as the funeral monument for Britons slaughtered by Hengist, the treacherous Saxon.)

Scientists have discovered a giant cavity at the bottom of a disintegrating glacier in Antarctica, sparking concerns that the ice sheet is melting more rapidly than expected.
Researchers working as part of a Nasa-led study found the cavern, which they said was 300 metres tall and two-thirds the size of Manhattan, at the bottom of the massive Thwaites glacier.

Nasa scientists have landed for the first time on one of the world’s newest islands, and discovered the three-year-old land mass is now covered in a sticky, mysterious mud, as well as vegetation and bird life.
The volcanic island sprang up in the ocean surrounding Tonga three years ago, one of only three new islands to emerge in the last 150 years that have survived more than a few months.

The fragrant jasmine rice growing on the left side of Kreaougkra Junpeng’s five-acre field stands nearly five feet tall.
Each plant has 15 or more tillers, or stalks, and the grains hang heavy from them. The Thai farmer says this will be his best-ever harvest in 30 years and he will reap it four weeks earlier than usual.
