How flowering plants conquered the world

How flowering plants conquered the world

Image copyright Getty Images Image caption Angiosperms produce flowers and fruits, which contain their seeds. Scientists think they have the answer to a puzzle that baffled even Charles Darwin: How flowers evolved and spread to become the dominant plants on Earth. Flowering plants, or angiosperms, make up about 90% of all living plant species, including […]

Female engineers set for success

Female engineers set for success

Image copyright Getty Images Image caption The UK needs to produce thousands more engineers Fewer than one in 10 engineers in the UK are female – the lowest percentage in Europe, according to the Women’s Engineering Society. Latvia, Bulgaria and Cyprus lead with nearly 30%. Here, two pioneering female engineers at Oxford University explain what […]

Citizen science bags five-planet haul

Image copyright NASA Image caption Artwork: The findings could shed light on the process by which planets form and then migrate within their systems A discovery by citizen scientists has led to the confirmation of a system of five planets orbiting a far-off star. Furthermore, the planets’ orbits are linked in a mathematical relationship called […]

Huge black hole blasts out ‘double burp’

Image copyright NASA/Stsci/CXC Image caption Arrows point to the the two burps of gas coming from the black hole; the top arrow points to the newer burp and the bottom arrow points to the older one Astronomers have caught a massive black hole letting out a “double burp” after bingeing on hot gas. When cosmic […]

Theresa May defends ‘long-term’ plastic waste plan

Image copyright Getty Images Theresa May has defended her 25-year plan to protect the environment as campaigners called for “emergency” action now. The prime minister said her long-term strategy, including eradicating all avoidable plastic waste in the UK by 2042, would allow future generations to “enjoy a beautiful environment”. Green groups said the proposals should […]

‘Serious gap’ in cosmic expansion rate hints at new physics

‘Serious gap’ in cosmic expansion rate hints at new physics

Image copyright NASA Image caption Artwork: The expansion of the Universe has been accelerating in the billions of years since the Big Bang A mathematical discrepancy in the expansion rate of the Universe is now “pretty serious”, and could point the way to a major discovery in physics, says a Nobel laureate. The most recent […]

Meet the butterflies from 200 million years ago

Image copyright Bas van de Schootbrugge Image caption One of the scales under the microscope Newly discovered fossils show that moths and butterflies have been on the planet for at least 200 million years. Scientists found fossilised butterfly scales the size of a speck of dust inside ancient rock from Germany. The find pushes back […]

Light shed on mystery space radio pulses

Light shed on mystery space radio pulses

Image copyright DR SETH SHOSTAK/SCIENCE PHOTO LIBRARY Image caption The analysis used data from the Arecibo Observatory in Puerto Rico Astronomers have fresh insight on a mysterious source of recurring radio pulses from space. Fast radio bursts (FRB) are one of the most persistent puzzles in astronomy. While usually short-lived, one source in the sky […]
