Nasa’s Curiosity rover uncovers evidence of Martian carbon cycle

1 week ago | eandt.theiet.org | Jack Loughran

Nasa’s Curiosity rover has uncovered evidence that ancient Mars had a carbon cycle, which increases the likelihood that the planet once harboured life. Scientists have long presumed that Mars featured an active water cycle in the past, as the landscape shows clear signs that liquid water once flowed across its surface. This would have required a much warmer climate than the planet has today and a thicker atmosphere with higher carbon dioxide (CO ) concentrations.
NHS approved to use robotic surgery systems to improve recovery times

1 week ago | eandt.theiet.org | Jack Loughran

The NHS has been approved to use 11 cutting-edge robotic surgery systems that could transform operations for thousands of NHS patients. The technology, which is capable of movements more precise than the human hand, has been given the green light by the National Institute for Health and Care Excellence (Nice), which provides evidence-based recommendations to the NHS.
Electrifying rail lines slashes toxic air pollution and cancer risk, study finds

1 week ago | eandt.theiet.org | Jack Loughran

Rail commuters experience dramatically improved air quality on board trains and at stations following rail line electrification, a study has found. Researchers from the University of California, Berkeley, analysed the air quality aboard the San Francisco Bay Area’s Caltrain commuter rail line, which was recently electrified. They installed black carbon detectors at a number of stations and carried air-quality detectors aboard the trains.
‘Cosmic radio’ detector could uncover dark matter within 15 years, scientists say

1 week ago | eandt.theiet.org | Jack Loughran

A ‘cosmic radio’ detector that could potentially discover dark matter in 15 years has been developed by a team of researchers. Dark matter is widely accepted to be a real phenomenon due to gravitational effects on galaxies and galaxy clusters that provide strong evidence for its presence. It is thought that it could account for around 85% of mass in the universe.
Sewage spills surge across UK as water firms fail to meet pollution targets

1 week ago | eandt.theiet.org | Jack Loughran

The UK’s water industry oversaw a 30% increase in pollution spillages in 2024 – despite trying to reduce incidents by 40% over that period. Surfers Against Sewage said there were almost 600,000 confirmed sewage discharges last year, although it suggests the true figure could be closer to a million. The charity’s latest water quality report tracked sewage spills via discharge and sickness data and personal reports filed by citizens through its app.
Climate change to cost UK households an average of £3,000 in 2025, report claims

1 week ago | eandt.theiet.org | Jack Loughran

Households in the UK are facing an average bill of £3,000 this year due to the impact of climate change, research by Global Witness has found. The NGO calculated that rising global temperatures will cause an estimated £1.1tn worth of damage to the UK’s economy over the next decade, amounting to roughly £38,000 over the period. In 2025 alone, it estimates households face a bundle of costs amounting to roughly £3,000.
Blue Origin sends first all-female crew to space including Katy Perry and Jeff Bezos’ fiancée

1 week ago | eandt.theiet.org | Jack Loughran

Blue Origin has landed its 11th human spaceflight carrying an all-female crew including pop star Katy Perry and Jeff Bezos’ fiancée Lauren Sánchez. The suborbital flight marked the first time an all-female space crew had been to space since the Vostok 6 solo mission of Soviet cosmonaut Valentina Tereshkova in 1963. It reached heights of around 100km and passed through the Kármán line – broadly recognised as the boundary between the Earth’s atmosphere and space.
Google sets sights on geothermal energy with new deal in Asia

1 week ago | eandt.theiet.org | Tanya Weaver

Google has signed a “first-ever” corporate agreement for geothermal energy in Taiwan with Baseload Capital. Tech giant Google has pledged to reach net zero emissions by 2030 – but, by its own admission, this is an “extremely ambitious goal”. Last year, its annual environmental report revealed that the company has fallen short of its climate goals, with its emissions in 2023 having risen 13% on the previous year, reaching 14.3 million metric tons. A lot of this is due to energy-hungry data centres.
Proposed grid reforms to axe ‘zombie’ projects and fast-track renewable power

1 week ago | eandt.theiet.org | Tanya Weaver

Energy regulator Ofgem has approved proposed reforms from the National Energy System Operator (NESO) to transform the grid connection process that will see clean energy projects prioritised. In its manifesto, Labour set itself the lofty goal of entirely decarbonising the UK’s energy grid by 2030. To achieve this, renewable energy projects need to be connected to the grid at pace.
British Steel blast furnaces to remain open as emergency supplies secured

1 week ago | eandt.theiet.org | Jack Loughran

The government has secured enough raw materials to keep British Steel’s blast furnaces operating in the short term while a steady pipeline is being arranged. The Department for Business and Trade (DBT) confirmed that coking coal and iron ore from the US are being imported and transported to the Scunthorpe site after it was forced to scramble for supplies following the rapid transfer of ownership from Chinese owners Jingye last week.
