Fingernail-sized robot autonomously travels 10 metres without battery power

Moving robots typically demand a lot of energy, which requires a battery that only has a limited lifetime. Researchers at the University of Washington (UW) have created MilliMobile, which is equipped with a solar panel-like energy harvester and four wheels. The robot is about the size of a penny, weighs as much as a raisin and can move roughly the length of a bus (approximately 10 metres) in an hour, even on a cloudy day. Image credit: Mark Stone University Of Washington The robot can also drive on surfaces such as concrete or packed soil and carry nearly three times its own weight in equipment, such as a camera or sensors. It uses a light sensor to move automatically toward light sources so it can run indefinitely on harvested power. “We took inspiration from…

Britain to build the world's most powerful laser

The UK Science and Technology Facilities Council (STFC) has been awarded £85m to upgrade its Vulcan system, with the aim of turning it into the most powerful laser in the world. The Central Laser Facility’s (CLF’s) current Vulcan laser has been delivering 1 petawatt (PW) pulses for more than 25 years. In contrast, the new laser will feature one beam capable of delivering 20PW pulses, alongside eight additional high-intensity beams producing a pulse energy of up to 20kJ. The updated Vulcan 20-20 will support the work of scientists studying nuclear fusion, plasma, new renewable energy sources and electromagnetic fields. “This is a 20-fold increase in power, which is expected to make it the most powerful laser in the world,” said funding body UK Research and Innovation. The laser is expected…

Averting Armageddon: the mission that knocked an asteroid off course

From the threat of artificial intelligence taking over the world to governments admitting to the presence of UFOs, we seem to be living in an era when the wildest imaginings of science fiction have unexpectedly morphed into reality. When the 1998 disaster movie Armageddon told the far-fetched story of a mission into space to destroy a meteor the size of Texas to prevent it from hitting Earth, few would have believed that a real planetary defence system would smash into an asteroid just over a couple of decades later. The Hollywood blockbuster is riddled with scientific inaccuracies, but its central premise of creating an explosion to knock an asteroid off course played out in our solar system in September last year when Nasa’s Double Asteroid Redirection Test (DART) successfully impacted…

Forecast Catastrophe: how a network of sensors saves lives in Colombia

If she has saved one life, that’s enough for Lina Cabellos, engineer, meteorologist and the driving force behind the Colombian city of Medellín’s ingenious early warning system – and that’s the answer she gives authorities when they ask about value for money. “Part of our success is to convince the government that these are services worth paying for,” she says. “Any life is worth saving. Here where we live in Medellín, emergencies happen all the time.” If the United Nations had its way, there’d be more networks like these, which reap insights from both technology and people on the ground to warn of impending danger. Only half of the world’s nations, many of them prone to extreme weather, have any kind of early warning system in place, as do just a third of small island states, “which…

FTC and 17 states sue Amazon for illegally maintaining market dominance

The US competition regulator and 17 state attorneys general have filed a lawsuit against the e-commerce giant after completing a year-long investigation into its business model. It is considered one of the biggest legal challenges the company has faced since its inception in 1994. In the filing , the FTC alleged that Amazon maintained its dominant position in the marketplace through a series of “anti-competitive and unfair” strategies that harmed competitors. Amazon has denied the allegations, saying the lawsuit is “wrong on the facts and law”. As part of the suit, the FTC has asked the court to issue a permanent injunction that would prohibit Amazon from engaging in its unlawful conduct and loosen its “monopolistic control to restore competition”. “The complaint sets forth detailed…

UK carbon capture projects consider moving abroad for more financial support

According to a study from the Carbon Capture and Storage Association (CCSA), greater support for the sector could secure around £40bn of inward investment by 2030. But without this, many projects are thinking about moving to countries that are backing the technology more vigorously. The CCSA wants the government to accelerate permitting and consenting options for carbon capture projects, make efforts to build public support for the sector and ensure “timely delivery” of its promised £20bn funding, which was announced in the Spring Budget. Since March 2022, the number of projects planned for the UK has grown from 55 to more than 90 – with enough schemes now in the pipeline to capture around 94 million tonnes of CO2 per year – up 29 per cent from 73 million tonnes last year. This is equivalent…

Development on controversial Rosebank oil field given the go-ahead

The North Sea Transition Authority (NSTA) gave consent to owners Equinor and Ithaca Energy to start developing at Rosebank, which is the UK’s biggest untapped oilfield. An NSTA spokesperson said: “We have today approved the Rosebank Field Development Plan, which allows the owners to proceed with their project. “The Field Development Plan is awarded in accordance with our published guidance and taking net zero considerations into account throughout the project’s life cycle.” It announced plans to issue more than 100 new oil and gas drilling licences in October last year in a bid to “boost” the UK’s energy sector, despite backlash from climate scientists. At the time, business and energy secretary Jacob Rees-Mogg insisted that the new exploration was compatible with the government’s legal…

UK tech sector valued at £817bn

UK tech start-ups are valued at $996.8bn (£817bn), up from $988bn (£812bn) last year, following a surge in the use of artificial intelligence tools. The valuation places the UK as the third-largest global tech player, behind the US and China. The numbers come as part of a new ‘Data Commons’ initiative from analysis firm Dealroom and HSBC Innovation Banking. The latter was launched earlier this summer and includes the former Silicon Valley Bank UK (SVB UK), which collapsed in March . The two organisations have partnered to analyse the overall health of the start-up and innovation industry in the UK, tracking data including job openings, active investors and capital injected into the UK. Their findings also showed that venture capital investment into UK start-ups has significantly…

1.5°C global warming limit still possible due to renewables growth, according to study

The Paris Agreement, which was signed in 2015, saw delegates from 196 countries meet to agree to cap global warming at “well below 2°C”, with a view to limiting this figure to 1.5°C above pre-industrial levels. The IEA’s 2023 Net Zero Roadmap update finds there have been “significant” changes to the energy landscape in the past two years, including “extraordinary growth” in some clean energy technologies. Nevertheless, it also finds that increased investment in fossil fuels is keeping emissions stubbornly high. Record growth in solar power capacity and electric car sales since 2021 are in line with a net zero emissions pathway by mid-century, as are industry plans for the roll-out of new manufacturing capacity for them. Those two technologies alone are estimated to deliver around one-third…

Water companies to pay back £114m for missing performance targets

The water industry regulator has accused the majority of water companies of “falling short” on the 2020-25 performance measures. According to Ofwat's latest company performance report, seven companies are said to be are “lagging” on their targets: Anglian Water, Dŵr Cymru, Southern Water, Thames Water, Yorkshire Water, Bristol Water and South East Water. In addition, 10 companies were placed in the “average” category, with none able to achieve the “leading” stage. The report is published annually by Ofwat and judges the companies’ performance in relation to a series of metrics, including pollution incidents, customer service and leakage. As a result of the poor performance, companies have been ordered to pay £114m back to customers. The money will be discounted from household bills…

Rolls-Royce nozzle breakthrough brings hydrogen plane engines closer to reality

The firm is working with partner easyJet to develop hydrogen combustion engine technology capable of powering a range of aircraft from the mid-2030s onwards. It said it completed tests on a full annular combustor of a Pearl 700 engine, which was running solely on hydrogen fuel. The test proves that the fuel can be combusted at conditions needed to achieve maximum take-off thrust. The engine used newly developed fuel spray nozzles to allow for precise control over the combustion process. “This involved overcoming significant engineering challenges as hydrogen burns far hotter and more rapidly than kerosene,” Rolls-Royce said. The nozzles, which were tested at Loughborough University’s recently upgraded National Centre for Combustion and Aerothermal Technology ( NCCAT), were able to control…

Nasa capsule brings back the largest asteroid sample ever collected

Nasa has made history once again by obtaining soil samples from the “most dangerous known rock in the Solar System”. The capsule carrying the samples landed at 8.52am MDT in the selected area of the Department of Defense’s Utah Test and Training Range near Salt Lake City. The mission was designed by Nasa’s Osiris-Rex (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) team, which aimed to obtain the third and largest sample ever collected from an asteroid. “We heard, ‘main chute detected,’ and I literally broke into tears,” Dante Lauretta, a University of Arizona scientist who has been involved in the project since its origin, told a press conference. Tim Prizer, a Lockheed Martin engineer on the project, said: “We touched down as soft as a…

Government ditches energy efficiency taskforce six months in

Rishi Sunak, the Prime Minister, has decided to scrap the home energy efficiency taskforce that his government established six months ago. The group was set up by Jeremy Hunt, the chancellor, to boost uptake of insulation and boiler upgrades, with a view towards reducing the country’s energy use by 15 per cent in the next seven years. The taskforce’s members included leading experts such as the chair of the National Infrastructure Commission Sir John Armitt. The group was chaired by the energy efficiency minister Lord Callanan and Dame Alison Rose, former chief executive of NatWest. However, Rose resigned from the position – and her role within the bank – in July following a row over the closure of Nigel Farage's account. Since its founding in March, the group met four times but was…

Backlash builds over possible scrapping of HS2 Manchester link

The government is facing criticism from politicians, industry groups and two former Conservative prime ministers over concerns it could decide to cancel the Northern link of the High Speed 2 ( HS2) line. The news was first reported by The Independent, which claimed the government had already spent £2.3bn on stage two of the high-speed railway, and was looking into the possibility of either scrapping its second stage to save up to £34bn or delaying the northern phase of HS2 by up to seven years. Sunak has refused to comment on the claims, stating that he remains “absolutely committed to levelling up and spreading opportunity around the country”. However, cabinet minister Grant Shapps told Sky News there could be a change to the “sequencing” and “pace” of HS2 due to the cost concerns. …

Green hydrogen sector hampered by high costs and lack of support – report

There are two approaches to producing hydrogen: blue hydrogen (made by splitting natural gas into hydrogen and carbon dioxide) and green hydrogen (produced by splitting water via electrolysis into hydrogen and oxygen). Green hydrogen requires a large energy input from a renewable source to be considered carbon neutral, but blue hydrogen cannot be described as a zero-emission fuel source unless coupled with significant carbon-capture efforts. One study showed that hydrogen derived from fossil fuels can actually be more carbon intensive than using gas. Some 95 per cent of today’s commercially produced product is blue hydrogen made by steam-methane reforming using natural gas feedstock. The number of announced projects for low-emissions hydrogen continues to expand rapidly while more than…

Carmakers urge the EU to delay 10 per cent tax on British cars

Because of Brexit, new tariffs will be imposed upon all cars made in the UK where at least 45 per cent of their components do not originate in the UK or EU. This quota is as high as 60 per cent for some components, such as the battery. A 10 per cent tax will be applied to all vehicles being sold across the English Channel not conforming to these specifications. The tariff is due to be enforced from January, but carmakers in the UK and EU want to delay its introduction by at least three years. The European Automobile Manufacturers’ Association (ACEA), which represents BMW, Ford and VW, said the new taxes could cost EU vehicle makers €4.3bn over the next three years, potentially reducing electric vehicle production by some 480,000 units, the equivalent output of two average-size car factories…

Climate change contributed to Libya’s devastating floods, study finds

The research team found that c limate change, civil war and international sanctions all contributed to the devastation caused by the destruction of two dams that released an estimated 30 million cubic metres of water into the city of Derna. A team of researchers at World Weather Attribution raced to understand the causes of the disaster. Their report found that climate change made the levels of rainfall that devastated the Mediterranean in early September up to 50 times more likely in Libya and up to 10 times more likely in Greece. The team also stressed that Derna residents were made more vulnerable due to factors such as building homes on floodplains, chopping down trees and not maintaining dams. “The interaction of these factors, and the very heavy rain that was worsened by climate…

Microsoft's reworked Activision deal gets preliminary UK approval

Microsoft's $68.7bn (£55bn) acquisition of Activision Blizzard is one step closer to being finalised in the UK after the Competition and Markets Authority (CMA) gave preliminary approval to the amended deal. The UK watchdog had blocked the acquisition over worries it would “alter the future of the fast-growing cloud gaming market”, leading to reduced innovation and fewer choices for UK gamers. In response, the company reworked the agreement, offering to sell Activision’s non-European streaming rights to Ubisoft Entertainment as a way to assuage the regulator's concerns. Microsoft said its new proposal was a “substantially different transaction” to the one proposed in 2022. The revised transaction would allow Ubisoft to commercialise these rights to other cloud gaming services providers…

Nasa’s plan to bring back Mars samples is not 'credible’, says review

The Mars Perseverance rover, which landed on the planet in 2021, has already been tasked with collecting samples of rock, regolith and atmosphere that will ultimately be sent back with Nasa’s sample retrieval lander (SRL). Expected to launch in 2028, the plan is to land the SRL on Mars where it will remain in place to receive the collection of samples collected by Perseverance. The lander would be the first to bring along a rocket and two helicopters that will be designed to send the samples into Mars’ orbit to meet the earth return orbiter, which would then take the samples the rest of the way home. But the review board identified a number of issues with the current plan that could hamper efforts to retrieve the samples unless a thorough revamp of the project is carried out. It said…

US proposes strict space junk rules for private firms to cut collision risk

It requires commercial space operators to choose from among five options to dispose of the upper stages of launch vehicles, including conducting a controlled re-entry moving the upper stage to a ‘graveyard orbit’ that lies away from common operational orbits sending the upper stage on an Earth escape orbit retrieving the upper stage within five years performing an uncontrolled atmospheric disposal. The last option would give firms 25 years for the upper stage to burn up in the Earth’s atmosphere. “Given that the entire mission lifetime of upper stages and their components is quite short, and spent upper stages pose a significant risk of debris propagation the longer they are in orbit, it may be appropriate to have a shorter disposal timeline of five years or another time period…
