• Sponsored: Engineering Canada

    For the last decade or so there have been reports indicating that many engineers in Canada will be retiring in the early 2020’s, and there is a shortage of engineers with specialised experience. These are ideal conditions when deciding whether or not to move to another country for work. Engineers that are willing to move where the work is will find that there are many prospects available to them. Travelling with an eTA Canada offers many different types of valid work permits and has concise information on their main government page informing immigrants how they can become citizens. This is especially true of specialised and highly skilled workers. There are multiple ways in Canada to become a citizen or a resident, and from the beginning you can be easily informed on what kinds of visas or…

  • Royal Mail launches drone delivery service for remote Orkney residents

    Skyports Drone Services has been selected to operate the service with Brazilian drone manufacturer Speedbird Aero. The electric multirotor DLV-2 drone, which has a payload capacity of 6kg and a range of up to 16km, was selected as vehicle of choice for the Orkney I-Port project due to its large payload volume, which makes it well suited to carrying cargo such as Royal Mail parcels. The aircraft is also equipped with a parachute. The first drone deliveries were completed in July this year and will continue until at least October. The mail is first transported from Royal Mail’s Kirkwall delivery office to Stromness which are both on the Orkney Mainland. Once at Stromness, the drones are used to complete the final step of the journey to transport items over to delivery staff on the islands…

  • Solar ‘umbrella’ could help slow down global warming

    István Szapudi, an astronomer at the University of Hawaiʻi Institute for Astronomy , has proposed building a solar “umbrella” that would shield the Earth from a fraction of the Sun’s light.  This is not the first time that scientists have proposed a “ solar shield ” approach to preventing climate change. However, the majority of proposals to date have been rejected due to the large amount of weight needed to make a shield large enough to balance gravitational forces and prevent solar radiation pressure from blowing it away.  Szapudi seems to have addressed this challenge by reducing the mass of the shield, while also using a captured asteroid as the counterweight. This would avoid the need to launch most of the device’s mass from Earth. “In Hawaiʻi, many use an umbrella to block the sunlight…

  • Machine learning algorithm trained in outer space

    Satellite data is increasingly useful for scientists, enabling aerial mapping and weather prediction, and monitoring deforestation. However, at present, most satellites can only collect this data passively, and transmit it to Earth for analysis.  But what if machine learning tools could work in outer space?  To overcome these restrictions, a group of researchers led by Vít Růžička, a PhD student at the University of Oxford, took on the challenge of training the first machine learning program in outer space . The team was able to partner with the Dashing Through The Stars mission, which had issued an open call for project proposals to be carried out on board the ION SCV004 satellite, launched in January 2022. During the autumn of that year, the team uplinked the code for the program to…

  • Supercapacitor made of concrete could provide renewable energy storage

    The inconsistency of renewable energy production is one reason why power grids are still reliant on fossil fuels. For example, solar panels cannot generate energy at night and wind turbines do not work when the air is still. But MIT researchers believe their energy storage device, which is a supercapacitor rather than a battery, could provide cheap storage of electrical energy that could help even out the ebb and flow of renewable energy generation. The technology could even be incorporated into the concrete foundation of a house, where it could store a full day’s worth of energy while adding little cost to the construction of the foundations while still providing the structural strength required. The researchers also envision a concrete roadway that could provide contactless recharging…

  • Lack of stock and species diversity hampering mass tree planting efforts

    The REPLANT Act, which was introduced in July 2020, provides money for the US Forest Service to plant more than a billion trees in the next nine years. The World Economic Forum also aims to help plant a trillion trees around the world by 2030 in an effort to soak up some of the excess carbon dioxide in the Earth’s atmosphere. But a University of Vermont (UVM) study has found that US tree nurseries don’t grow nearly enough trees or have the species diversity needed to meet the ambitious plans. “Trees are this amazing natural solution to a lot of our challenges, including climate change. We urgently need to plant many millions of them,” said UVM scientist Tony D’Amato, who co-led the new research. “But what this paper points out is that we are woefully underserved by any kind of regional…

  • ‘Urgent need’ for long-term nuclear energy plan, MPs say

    In a new report, the Science, Innovation and Technology Committee (SITC) said that current efforts are more of a “wish list” than the comprehensive strategy that is required to ensure such capacity is built. The government’s plan to install 24GW of nuclear capacity is almost double the highest installed capacity the UK has ever achieved. Efforts to meet it could involve new gigawatt-scale nuclear power, small modular reactors (SMRs) and advanced modular reactors (AMRs), alongside further development of nuclear fusion, the committee said. But it would require “substantial” progress on technologies, financing, skills, regulation, decommissioning and waste management, it added. Nuclear industry witnesses who were interviewed for the report called for a clearer strategic plan than currently…

  • A third of US working hours could be automated by 2030, report finds

    Women are 50 per cent more likely to change jobs by the end of the decade, the  study found after analysing the impact of automation and artificial intelligence (AI) tools on the US workforce.  The report, published by the McKinsey Global Institute, found that around a third of the country’s working hours could be automated by 2030. The shift is expected to mostly affect people in low-wage positions and workers in food services, customer services and sales, of which women make up a majority.  Black and Hispanic workers, workers without college degrees, and the youngest and oldest workers also are more likely to have to find new jobs by 2030, the study says. “Workers in lower-wage jobs are up to 14 times more likely to need to change occupations than those in highest-wage positions, and…

  • British-built satellite Aeolus successfully crashed into the Atlantic

    The British-built satellite Aeolus has reached its final resting place: the Atlantic Ocean.  The re-entry of the weather satellite was guided by mission controllers at the European Space Agency (ESA), using what little fuel remained onboard. It has been hailed as the first time a defunct satellite has undergone such a controlled re-entry on Earth.  Aeolus has been one of ESA’s most successful Earth observation missions. The 1,360kg satellite was built by Airbus Defence and Space in Stevenage, and it became the first satellite mission to acquire profiles of Earth’s wind on a global scale. The satellite was originally due to end its life after three years in orbit, but its mission was extended by almost two additional years, coming to an end on 28 July 2023. Aeolus…

  • New North Sea oil licences send ‘wrecking ball’ through UK climate policy

    In order for the new licences not to compromise the UK’s net zero plans, the government also confirmed a raft of new carbon capture and storage (CCS) facilities designed to negate the emissions created by the extracted fossil fuels. This includes projects in Acorn in north-east Scotland and Viking in the Humber that have been chosen as the third and fourth CCS clusters in the UK. These projects follow pre-existing plans to deploy CCS in two industrial clusters by the mid-2020s – the HyNet cluster in north-west England and north Wales, and the East Coast cluster on Teesside and the Humber. But CCS technology has attracted criticism from climate campaigners who believe it is being used by high-carbon industries to ‘greenwash’ their operations . According to a coalition of human rights and…

  • Researchers simulate the sound of twinkling stars

    The Northwestern University-led team has developed the first 3D simulations of energy rippling from a massive star’s core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle. The team then converted these gas waves  into sound waves, enabling listeners to hear both what the insides of stars and the “twinkling” should sound like .  “Motions in the cores of stars launch waves like those on the ocean,” said Evan Anders,  who led the study. “When the waves arrive at the star’s surface, they make it twinkle in a way that astronomers may be able to observe. “F or the first time, we have developed computer models that allow us to determine how much a star should twinkle as a result of these waves. This work allows…

  • Changes in social media algorithms did not reduce political polarisation, study finds

    The results of the research found that tweaking the platform’s features had an impact on the content users were shown on their feeds, but it did not alter their political ideology or opinions of the candidates. This was one of the conclusions found in the first four papers published as part of the   US 2020 Facebook and Instagram Election Study,  a partnership between Meta researchers and independent external academics that was prompted by accusations that Facebook and Instagram algorithms amplified misinformation and political polarisation. In order to shed light on the topic, the researchers analysed data from millions of Facebook and Instagram users and experimented with the algorithms of those who agreed to take part in the project. The team’s conclusions pointed out the existence…

  • Greater public trust in AI would help NHS detect cancers early, experts say

    A collection of studies has been released by the National Institute for Health and Care Research (NIHR) identifying 10 “promising AI interventions” that would help to address specific healthcare challenges. These include early detection of heart disease and lung cancer, predicting the progression of disease, personalising treatments to the patient, and reducing pressures on A&E departments. Dr Jemma Kwint, NIHR senior research fellow and author of the report, said: “We all need to be able to trust AI and ensure that it does not increase inequalities in care. The high-quality studies are useful examples of the evidence we need to build trust in this advancing technology. “Further research is needed to deepen our understanding of how these tools could work in routine clinical practice,…

  • ‘Time-travelling’ pathogens could cause major environmental damage

    Using computer simulations, scientists have predicted that the release of only 1 per cent of dormant pathogens could cause major global environmental damage.  These pathogens have been frozen in ice and permafrost for millennia. However, rising global temperatures could cause these materials to melt, releasing the microbes.  To better understand this hypothetical scenario, researchers have simulated experiments where digital pathogens from the past invade communities of bacteria-like hosts. They then compared the effects of the invading pathogens on the diversity of host bacteria to those in communities where no invasions occurred. The results of the study showed that the ancient invading pathogens could often survive and evolve in the modern world, with about 3 per cent becoming dominant…

  • Connected vehicles could detect road dangers before accidents happen

    Connected vehicles can collect data including road and traffic conditions, emergency alerts and the behaviour of other drivers. They can also generate data about extreme manoeuvres from drivers – such as harsh braking – that is accurately geolocated to particular points on the road network. Once acquired, this data can give highway engineers insights into which locations need to be looked at, such as those where there are repeated indications of emergency manoeuvres. This can also help identify the causes of these manoeuvres such as a hidden junction, regularly queueing traffic or even a damaged road surface. Efforts can then be made to maintain the road or change its layout before a serious crash takes place. The RAC Foundation also suggested that the data could be used to dynamically…

  • Europe to cover its highways with EV chargers from 2025

    The new law is expected to ensure that electric vehicle (EV) owners can travel across the continent with complete coverage, as well as reduce the bloc’s carbon emissions. Under the new requirements, governments will be expected to install  charging stations offering at least 150kW of power to be installed along the EU’s Trans-European Transport Network (TEN-T) system of highways, the bloc’s main transport corridor.  The same distance requirements for heavy goods vehicles will need to be met by 2030, while airports and ports will need to provide electricity for passenger vessels and aircraft from 2025. “The new law is a milestone,” said Raquel Sánchez Jiménez, Spain’s Minister of Transport. “We are optimistic that in the near future citizens will be able to charge their electric cars as…

  • Tiny surgical robot can travel deep into lungs to detect early cancer signs

    The tentacle-like device, which measures just 2mm in diameter and is controlled by magnets, paves the way for a more accurate and less invasive approach to treatment. It can reach some of the smallest bronchial tubes and could transform the treatment of lung cancer, the team said. The researchers tested the robot on the lungs of a cadaver and found that it can travel 37 per cent deeper than the standard equipment and leads to less tissue damage. Research supervisor Professor Pietro Valdastri said: “This is a really exciting development. This new approach has the advantage of being specific to the anatomy, softer than the anatomy and fully-shape controllable via magnetics. These three main features have the potential to revolutionise navigation inside the body.” Lung cancer has the highest…

  • ‘Infinitely recyclable’ plastics created using engineered microbes

    Unlike glass and aluminium, every time plastic is recycled, the polymer chain grows shorter which decreases its quality. The same piece of plastic can only be recycled about 2-3 times before it can no longer be used to make new products. But a team of researchers at three facilities at the US Department of Energy’s Lawrence Berkeley National Laboratory have developed an infinitely recyclable plastic known as poly(diketoenamine), or PDK. “This is the first time that bioproducts have been integrated to make a PDK that is predominantly bio-based,” said Brett Helms, staff scientist at the Molecular Foundry who led the project. “And it’s the first time that you see a bio-advantage over using petrochemicals, both with respect to the material’s properties and the cost of producing it at scale…

  • Climate change ramping up faster in Asia than rest of the world

    In a new report, the body said that said that melting glaciers alongside rising sea levels raises the prospect of more disruption in the future. Asia is currently warming faster than the global average. There were 81 weather, climate and water-related disasters in Asia in 2022, of which 83 per cent were flood and storm events. These disasters caused the deaths of more than 5,000 people, affected the lives of a further 50 million people and caused more than $36bn (£28bn) in economic damages. “In 2022, many areas in Asia experienced drier-than-normal conditions and drought. China, in particular, suffered prolonged drought conditions, which affected water availability and the power supply. The estimated economic losses from the drought affecting many regions in China were over $7.6bn. Pakistan…

  • US hid conducted a ‘multi-decade’ UFO programme, whistleblower claims

    The declarations have been made during a historic hearing of the House Oversight Committee, focused on the issue of unidentified anomalous phenomenon (UAPs) and the need for more transparency on the subject from the military. The session was opened by the committee’s Republican chairman Glenn Grothman, who stated that a “lack of transparency” had fuelled “wild speculation” and eroded “public trust” in government institutions. The Committee then heard from several witnesses who claimed they had first-hand experience of interacting with objects that seemed to defy the laws of physics, stating that they posed a national security problem.  David Grusch, a former leader of the US Department of Defense’s UAP programme, claimed the government conducted a “multi-decade” programme aimed at analysing…

  • E-bike batteries should fall under the same rules as fireworks, charity says

    Batteries for e-bikes and e-scooters should be regulated like fireworks and heavy machinery to better ensure their safety, according to the Electrical Safety First (ESF)   Battery Breakdown report . Currently, e-bikes and e-scooter manufacturers can self-declare whether their products meet safety standards. However, the charity argues that the batteries should be reviewed by a third party before being placed in the UK market due to the risk of fires they pose. The recommendation is similar to the requirements made for specific products such as  pyrotechnics, heavy machinery and medical devices. It also resembles the requirements introduced in New York City in March 2023 following a spate of fatal fires. The report also follows rising international concern over the risk of fires posed…

  • Advanced imaging technique could boost Great Barrier Reef recovery

    Covering less than 0.1 per cent of the ocean surface, coral reefs support 25 per cent of all marine life. But according to Unesco, 21 of 29 World Heritage reefs have been damaged through heat stress and bleaching. In warmer or polluted waters, corals expel algae, which provide sustenance through photosynthesis; the corals then turn white and can die if the water temperature remains high. Following the latest bleaching, the world’s largest coral reef ecosystem, parts of the Great Barrier Reef off the coast of Queensland, Australia, is estimated to have lost two-thirds of its corals, mainly in the northern section. The newly developed method is being used to monitor the recruitment success of newly settled corals through an artificial process whereby microscopic larvae are raised in floating…

  • BT start-up plans to turn 60,000 street cabinets into EV charging points

    BT’s start-up and innovation company Etc. has today announced it will begin pilots to transform decommissioned street cabinets into EV charging points in a bid to accelerate the UK’s journey to net zero.  The first phase of the pilots will take place in Northern Ireland this autumn. If successful, it will be expanded to the public with more pilot locations added across the UK later in the year. A study from 2021 found that the installation of chargers needs to   increase by five times   the current rate if the plan to phase out petrol and diesel vehicles by 2030 is to be achieved. BT said the pilots will provide critical insight into the viability of scaling up EV charging to more locations across its estate.   “With the ban on sales of internal combustion engine vehicles coming in…

  • UK will fail to protect 30 per cent of English land and seas without action, peers say

    A report from the House of Lords Environment and Climate Change Committee said that an “urgent step change” is needed if the target is going to be delivered on time. It found that only around 6.5 per cent of natural habitats in England are effectively protected. An additional three million hectares (23.5 per cent) will need to be given protected status in order to achieve the ‘30 by 30’ target. This equates to an area roughly one and a half times the size of Wales. The report said that improving nature in England would bring a host of benefits, including improvements to public health and wellbeing as well as tackling climate change. Protected areas in England will also play an important role in restoring nature and meeting internationally agreed biodiversity targets. It concluded that…
