Country diary: Phacelia is the most useful plant – I always have a packet for my garden |
Allendale, Northumberland: Farmers use it as cover crop, and I sow it into bare soil – but not before I’ve had a close look at its stunning detailsCupped by bristly sepals, the five-petalled flowers of phacelia flare open at the tips, drawing insects to their abundant nectar and
World's first superconducting quantum heat engine offers path to larger quantum computers
World's first superconducting quantum heat engine offers path to larger quantum computers
Recent improvements in our understanding of how the principles of thermodynamics apply in the quantum realm could give a boost to quantum technology, and a clearer picture of quantum thermodynamics could in turn enhance our understanding of classical thermodynamics. Now, Aalto Un

China's 'Green Great Wall' tames desert growth, but scientists warn the fight is not over
For half a century, millions of workers have repeated a task across the deserts in northern China: inserting forearm-length sticks into shifting sand, first in a row, then in an intersecting line, gradually forming a grid. Then saplings are planted at the center of each small squ
Physicists say quantum mechanics may not need imaginary numbers after all
Physicists say quantum mechanics may not need imaginary numbers after all
Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to
Banned chemicals continue to endanger environmental health in the Middle East and North Af
Banned chemicals continue to endanger environmental health in the Middle East and North Af
In a study recently published in the journal Environmental Research, scientists from the University of Sharjah have drawn renewed attention to contamination by polybrominated diphenyl ethers (PBDEs), a class of man-made chemicals formerly used as flame retardants in a wide range
Only 13% of biodiversity promises from 180 influential companies pass accountability test
Only 13% of biodiversity promises from 180 influential companies pass accountability test
New research by the University of Oxford and the Stockholm Resilience Centre at Stockholm University has revealed that most biodiversity commitments made by large, influential companies are not precise enough to enable society to evaluate whether they are making progress toward m
RNA-only repair enzyme reveals how primordial life could have protected genomes
RNA-only repair enzyme reveals how primordial life could have protected genomes
In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first place.
Stephen Hawking's black hole laws just got a major upgrade
Stephen Hawking's black hole laws just got a major upgrade
Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones. The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wav
New 200Gbps photodetector doubles optical reception capacity for data centers
New 200Gbps photodetector doubles optical reception capacity for data centers
Korean researchers have developed, for the first time in Korea, a 200Gbps-class photodetector device for use in hyperscale AI data centers and 5G/6G mobile communications infrastructure. The technology enables ultrahigh-speed data reception fast enough to transmit five 5GB full H
Computer-guided electricity rapidly transforms flat nanofilms into 3D shapes on demand
Computer-guided electricity rapidly transforms flat nanofilms into 3D shapes on demand
Researchers at Nagoya University in Japan have developed a method to form dome-shaped bumps on nanofilms in water using a computer-guided electron beam. The bumps form within 10 seconds and can be flattened, reshaped or repositioned as needed.

Weather tracker: Unusually warm rivers affect French nuclear power plants
High temperatures and below average rainfall put pressure on waterways used to cool reactorsAbove average temperatures combined with below average rainfall across much of western and central Europe during June and the first half of July have placed increasing pressure on rivers,
Scientists strike invisible gold in the deep sea—locked inside fool's gold
Scientists strike invisible gold in the deep sea—locked inside fool's gold
Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers (220 miles) south of Tokyo, scientists have uncovered inv
