After watching LauncherOne abort, I felt briefly dejected. But our attempts to put these tiny satellites into space will pay offJust like any expectant parent, I had a bag packed and was waiting by the front door. In these situations you never know when things will kick off, so it’s best to be prepared. The birth that I was waiting for was not a child, but the UK’s new launch capability to get baby satellites (known as microsatellites) into space from right here in Britain.As a space scientist, and builder of satellites myself, I know of the frustration of a launch. Here in the UK we have developed an industry in small dynamic satellites. Microsatellites, unlike their larger brethren, can be turned around quickly. I spent part of my career working on the James Webb space telescope, a wonderful piece of hi-tech engineering designed to give us amazing new insight into the early universe and how it evolved. But it took about 40 years to develop, from concept to launch. Continue reading...

Scientists say sensual discovery could be used to design low-fat product that mimics feel of high fatThe irresistible melt-in-the-mouth sensation of chocolate comes down to the way it lubricates the tongue, according to scientists.A study investigated the physical process by which a solid square of chocolate morphs into a smooth emulsion. It found that chocolate released a fatty film that coats the tongue, giving a smooth sensation for the entire time it is in the mouth. Continue reading...

Although many are attributed to drones or balloons, others point to the spying capabilities of rival nationsThe US government is examining 510 UFO reports, more than triple the number in its 2021 file. While many were caused by drones or balloons, hundreds remain unexplained, according to a report released on Thursday.The 2022 report (pdf) by the Director of National Intelligence (DNI) said that 247 “unidentified anomalous phenomena” or UAP reports have been filed with it since June 2021, when it revealed that it had records of 144 sightings of suspicious aerial objects under examination.

Women are increasingly discussing the forgetfulness, anxiety and suicidal thoughts they have experienced as their hormones change in midlife. Why is more help not available?At her lowest point, Karen Arthur came within a hair’s breadth of killing herself. Having been signed off from her teaching job with anxiety, which she had not then connected with going through the menopause, the 51-year-old had booked a few days away from home to try to clear her head. A long walk in the country brought her to a spot notorious for suicide attempts.At that stage, she says, she had not considered how she might kill herself, but she had put her affairs in order for her two daughters, who were away at university. “I did think it would be easier if I wasn’t here. The kids would get the house, the mortgage paid off.” Continue reading...

Fans say the use of an accurate physics engine to reimagine historic shipwrecks makes it ‘difficult to look away’A shark swims slowly and serenely beneath the Bismarck seconds before it sinks deep into the ocean. Seemingly out of nowhere, the battleship tilts and falls; its bow crashes on to the seabed. Its hull floods before briefly resurfacing out of the water. Then the voiceover says: “Oh! Uh oh, uh oh, uh oh! Boom!” The Bismarck snaps in half and sinks.This was not the Bismarck’s real end, but a shipwreck simulated by Alex Reifsnyder, a 27-year-old retail supervisor from Pennsylvania. Reifsnyder uses the physics simulator Floating Sandbox to sink ships with tidal waves, icebergs and lightning for between one and two hours almost every night. On his TikTok page @an_angry_flyy, 167,000 loyal followers cannot get enough. Continue reading...

Group says forcing polluters to store carbon dioxide underground is needed to help world reach net zeroFossil fuel companies should be forced to “take back” the carbon dioxide emitted from their products, handing them direct responsibility for cleaning up the climate, a group of scientists has argued.The principle that the producer of pollution should pay for its clean-up is established around the world, but has never been applied to the climate crisis.

The peculiar hush is partly due to less human activity, but also down to snow’s acoustic damping effectGoing outside after a snowfall can be magical, with the spectacle of a winter wonderland underlined by the change in the soundscape. Suddenly, all is quiet.The peculiar hush is partly due to the reduction in human activity. There are fewer people and less traffic about, often fewer planes and trains. Building sites, road mending and other sources of noise fall silent. Birdsong is equally subdued. Continue reading...

A UN report has found the Earth’s ozone layer is on course to be healed within the next 40 years. What was once humanity’s most feared environmental peril is now an example of how the world can take collective action. Madeleine Finlay speaks to atmospheric scientist Paul Newman about this momentous achievement and whether it really is the end of the storyThe ozone layer is an important part of the Earth’s atmosphere that absorbs ultraviolet radiation from the sun. After alarm over the loss of the ozone layer in the 1980s, governments signed the Montreal protocol in 1987, an international agreement that has helped eliminate 99% of ozone-depleting chemicals, such as chlorofluorocarbons that were used as solvents and refrigerants.Since then, scientists have been monitoring levels of CFCs in the atmosphere and ozone depletion. This week, a UN report found that it is set to be completely healed by 2066. Madeleine Finlay speaks to Paul Newman, the chief scientist for earth sciences at Nasa’s Goddard Space Flight Centre, about how this was achieved and what it means for the climate crisis.

The 70s for over-60s | Essential services | ‘Working’ royals | Wordsearch | Coming outProf Rob Ford seems to have a very dim view of the ability of individuals to remember anything before they were adult if he really thinks that you need to be aged over 60 to have any “meaningful memory” of 1978 (Carrots, sticks and Thatcher replays: what is Sunak’s strikes strategy?, 6 January). I am over 60, but I vividly remember Churchill’s state funeral (when I was not yet six), the moon landing (aged 10), Harold Wilson as the first Labour prime minister in my lifetime (11), Ted Heath and the three-day week, and so on.

Teams behind historic mission describe tearful scenes but express determination to try again

Study suggests 23m years of evolutionary history could be wiped out if the island’s endangered mammals go extinctFrom the ring-tailed lemur to the aye-aye, a nocturnal primate, more than 20m years of unique evolutionary history could be wiped from the planet if nothing is done to stop Madagascar’s threatened mammals going extinct, according to a new study.It would already take 3m years to recover the diversity of mammal species driven to extinction since humans settled on the island 2,500 years ago. But much more is at risk in the coming decades: if threatened mammal species on Madagascar go extinct, life forms created by 23m years of evolutionary history will be destroyed. Continue reading...

Sanger Institute initiative could lead to single test allowing more effective vaccines and treatmentsAt the peak of the Covid pandemic, UK labs were sequencing thousands of Sars-CoV-2 genomes a day to keep track of circulating variants, and identify any new ones that emerged.Now researchers at the Sanger Institute are launching a project that could ultimately achieve something similar for the numerous other respiratory viruses that make us sick – and fill up UK hospital beds – each year.

Gaping hole mysteriously appears where former PM once stood at UK space mission with business secretary

A historic space mission that took off from Cornwall, in south-west England, has ended in bitter disappointment after a rocket carrying the first satellites launched from British soil failed to reach orbit and was lost.Virgin Orbit, which is leading the mission, announced there had been 'an anomaly' and the rocket failed to reach the required altitude. The rocket and satellites were lost but the UK Space Agency insisted they posed no danger and were expected to burn or break up over the north Atlantic. The 747 returned to Cornwall safely

Last year saw several major science breakthroughs – from the first time a nuclear fusion experiment produced more energy than it used, to Nasa smashing a spacecraft into an asteroid in a mission that demonstrated the possibility of redirecting any space rocks heading our way.

Swimming-induced pulmonary oedema involves the accumulation of fluid in the lungs of swimmers without it having been inhaledA potentially life-threatening condition that can affect fit and healthy open-water swimmers causing them to “drown from the inside” may involve a buildup of fluid in the heart muscle, researchers have suggested.Swimming-induced pulmonary oedema – SIPE – is a form of immersion pulmonary oedema and involves the accumulation of fluid in the lungs of swimmers without it having been inhaled. The condition is thought to be a result of increased pressure on the body’s blood vessels as a result of exertion, immersion and cold. Continue reading...

Analysis will help improve treatment for millions affected by poorly understood conditionScientists have mapped the cellular changes linked to endometriosis to help improve therapeutic options for the millions of women affected by the disease.Roughly 1 in 10 women are affected by the condition, which is characterised by cells similar to those lining the uterus growing elsewhere in the body – most commonly on the ovaries, fallopian tubes and in the abdominal cavity. Patients with the disorder can experience chronic pain, infertility, headaches and fatigue, as well as bowel and bladder dysfunction. Despite it being so common, it takes an average of seven to eight years to be diagnosed with endometriosis because it is so poorly understood. Continue reading...

Scientists in Italy are testing the impact of fire and drought to learn how the changing climate affects underground fungal networksWhen Toby Kiers and a group of fungi experts hiked the Apennine mountains in northern Italy last July, the country was experiencing its worst drought for 70 years. But Kiers, an evolutionary biologist at Vrije Universiteit Amsterdam, saw the dried vegetation and burnt forests of the drought- and fire-stricken areas bordering Tuscany and Emilia-Romagna as a unique learning opportunity.Armed with rubber mallets, measuring tape and GPS devices, Kiers and her team were investigating a very particular life form: the bustling fungal life beneath their feet.

Guardian is given unique access to observe procedure that can radically improve outcomes for babies with spina bifidaEmily Ellis flicks through photos of her four-day-old baby, Austin, on her phone. “He is perfect,” she says with the certainty of any new parent. But the journey to his arrival has been more complicated than most. Austin has spina bifida and is one of a growing number of babies in the UK to have undergone a pioneering foetal surgery that is transforming outcomes for infants with the condition.Before his birth, surgeons at King’s College hospital operated on Austin’s spinal defect while he was still inside the womb and the Guardian was given unique access to observe the same procedure on another mother and baby from inside the operating theatre. The procedure is not a cure, but could be the difference between Austin walking or not. Continue reading...

Warming seas almost certainly prompted the huge mammal’s wanderings, even if deniers claim all is well in the ArcticAs migrant arrivals go, the appearance of Thor the Walrus in British waters last week was encouraging. Thousands flocked to greet the huge mammal as he meandered up England’s east coast after his arrival in Hampshire in December.Subsequent stopovers included Scarborough, where the local council cancelled New Year’s Eve celebrations so they did not frighten Thor, who gratefully responded by masturbating. Then he moved on to Blyth, in Northumberland, before heading home to the Arctic.Do you have an opinion on the issues raised in this article?

Wildlife photography contest that was subject to the agreement described environmental impact of oil rigs in positive lightThe Natural History Museum has been denounced for signing a contract with a gagging clause that prevented it from criticising a Danish oil company that sponsored its wildlife photography competition.The clause was put into a contract with Dong Energy in 2016 when the company was heavily invested in oil and gas. Dong changed its name to Ørsted in 2017 when it divested of fossil fuels to focus on renewables. Continue reading...

Harvests that form a vital element of the diets of 4.5 billion people are being devastated by global heating. Now research has found a key to create a heat-resistant varietyIt is the plant that changed humanity. Thanks to the cultivation of wheat, Homo sapiens was able to feed itself in ever-increasing numbers, transforming groups of hunter-gatherers struggling to survive in a hostile world into rulers of the planet.In the process, a species of wild grass that was once confined to a small part of the Middle East now covers vast stretches of the Earth. As the historian Yuval Noah Harari has observed: “In the great plains of North America, where not a single wheat stalk grew 10,000 years ago, you can today walk for hundreds upon hundreds of kilometres without encountering any other plant.” Continue reading...

Memorial spaceflights offer people in New Zealand a new way to say goodbye, sending tokens holding their ashes into orbitOn 19 January, Keryn Townsley will be hoping for a clear night sky. Her family will gather at their home in Wellington, New Zealand, to watch a live stream of a rocket launching in the US – a tradition they have observed many times in the past. But this time will be different. On board the rocket will be a small inscribed metal token holding a portion of ashes belonging to 14-year-old Remy – Townsley’s rocket-loving son – who died suddenly in 2020.His ashes will orbit Earth for up to 10 years, before crashing back through the atmosphere and burning up. “He will always be stardust up there and that has meaning for us,” Townsley says, of choosing to memorialise her son in what is known as a “space burial”.

Humanity is now a ‘geological superpower’ and declaring a new epoch is critical to tackling its impact, scientists sayExactly where and when did the Anthropocene begin? Scientists are attempting to answer this epochal question in the coming months by choosing a place and time to represent the moment when humanity became a “geological superpower”, overwhelming the natural processes that have governed Earth for billions of years.They could decide the start is marked with a bang, thanks to the plutonium isotopes rapidly blasted around the planet by the hydrogen bomb tests that began in late 1952, or with a shower of soot particles from the surge in fossil-fuel power plants after the second world war.
