Telescope reminds us of the debt we owe Vera Rubin
Vera C Rubin's work did much to demystify the heavens

T he American astronomer Vera C Rubin, who died in 2016, was certainly given enormous recognition and credit for her work in her lifetime. Her stellar career led to medals, prizes and awards all over the world. She did not, however, receive the Nobel prize for physics for her pioneering study of galaxy rotation rates in the 1960s and 1970s, work subsequently accepted as strong evidence for the existence of dark matter. Dark matter and dark energy are now thought to comprise 95 per cent of the mass-energy content of the universe.
Rubin had to battle prejudice against women in science for many decades. If she did miss out on a Nobel because of her gender, she would not be alone. The shabby failure to fully credit Rosalind Franklin's contribution to the double helix breakthrough is well known. Lisa Meitner, 'the mother of the atomic bomb', was even more ruthlessly snubbed, while her partner in nuclear fission research, Otto Hahn, bagged a Nobel.
The brilliance of Marietta Blau, Jocelyn Bell Burnell and Chien-Shiung Wu was also overlooked by Stockholm, while many of their male collaborators were laureated. In Rubin's own field, the great Edwin Hubble, whose work drew on that of Henrietta Swan Leavitt, acknowledged the huge debt he owed her.
Just as Hubble gave his name to a revolutionary telescope, so too did Rubin, when the Large Synoptic Survey Telescope in Chile was renamed the Vera C Rubin Observatory in her honour. The first images from this huge yet agile device were published this week, capturing 2,000 undetected asteroids within ten hours. Over the next decade, the southern night sky will be continuously mapped and supernova explosions from billions of years ago will be traced. If our solar system does have a mysterious Planet Nine, Rubin will find it.
Perhaps somewhere in those heavens she did so much to demystify, Vera Rubin is having the last laugh.

Taxpayer cash spent on studying whiteness and helping women called ‘witches'
TAXPAYERS' cash is being blown on studying whiteness in South America and helping women called 'witches' to sing, a dossier reveals. An investigation found £16.5 million is being spent on 21 'woke' research projects at UK unis. They include almost £85k on a Newcastle University project called 'Combating Witchcraft-Related Violence through Song'. It looks at how singing helps elderly women in South Africa abused for being a 'witch' due to their ageing features. Over £1million has been earmarked for a University of Nottingham project 'decolonising' photos from British Malaya. A further £246k has been put aside for Sheffield University to develop a city tour app exploring 'whiteness' in statues and monuments in Chile. Nearly £783k is being spent by Queen Mary University of London on a scheme looking at 'Military Decarbonisation'. And £379k is going towards a Birkbeck College programme on children's crafting in West Africa. Cash was handed out by quango UK Research and Innovation. They were uncovered by founder of Doge UK Charlotte Gill, who said taxpayers will be 'fuming' to see where their cash goes. She said: 'Unfortunately this is just the tip of the iceberg, with thousands of similar taxpayer-funded grants being awarded under the UKRI - never mind the vast sums spent on the rest of the public sector.' A UKRI spokesperson said: 'International research collaboration is vital to help us tackle global challenges in a complex and interconnected world, improving security and prosperity in the UK and internationally. "Projects are prioritised for funding through independent expert peer review, as set out in the Higher Education and Research Act.'

Mark Zuckerberg's charity backing away from DEI and political spending after Trump criticisms and staff tensions: report
The Chan Zuckerberg Initiative, the multi-billion-dollar philanthropy led by Meta CEO Mark Zuckerberg and his wife Dr. Priscilla Chan, is reportedly moving away from political spending, following criticism from Republicans and internal tensions with liberal staff members. The initiative, founded in 2015, always invested in a combination of social and scientific causes, but has recently rebranded as 'science-first,' and has ended internal diversity programs, housing initiatives, and diversity-focused funding for scientists. This spring, a school for low-income students that Chan founded also closed. The shift, which has also included an overall slowdown in spending, with $336 million in grants, less than half the group's average, came after a series of bruising encounters with politics, The New York Times reports. Chan and Zuckerberg were reportedly frustrated after getting criticism from Trump and his allies for efforts like donating $400 million to nonpartisan election infrastructure in the 2020 race, an effort MAGA derided as 'Zuckerberg bucks.' Trump, for his part, threatened the Meta boss with 'life in prison' during the 2024 campaign if he intervened in the election. Political fatigue reportedly began even earlier, according to the Times, with Zuckerberg growing frustrated with criticisms from liberal staff members at the philanthropy in the wake of the 2020 racial justice protests. The Independent has contacted the Chan Zuckerberg Initiative for comment. The organization has explained the changes as a combination of new strategy and a shifting political landscape. In a June letter, Chan, a pediatrician, emphasized the group's long-running commitment to curing disease, a cause she became attached to as a doctor in San Francisco. 'It was there that I saw the limits of medicine and science up close, working with children with rare diseases,' she wrote in a June blog post. 'For those families, expanding the limits of what we know — advancing basic science research — is their only hope for a better life for their child. In a February post, the initiative explained its decision to cut its DEI teams as a response to the ' shifting regulatory and legal landscape.' In recent years, the Supreme Court has struck down race-based affirmative action in higher education admissions, and the Trump administration has sought to end DEI in both the public and private sector. At the same time, as the Republican has returned to power, Meta has repositioned itself with moves seen by some as an attempt to remain in the administration's good graces, including ending diversity programs, eliminating fact-checkers, putting Trump ally Dana White on the Meta board, and attending the president's inauguration earlier this year. Shortly after Trump was elected, Zuckerberg was spotted at Trump's Mar-a-Lago estate, where senior White House official Stephen Miller said the tech billionaire had 'been very clear about his desire to be a supporter of and a participant in this change that we're seeing all around America, all around the world, with this reform movement that Donald Trump is leading.'

The American women who are making Elon Musk's doomsday prediction a reality
Elon Musk has warned for years that 'population collapse' is a bigger threat to civilization than climate change. Now, new research has suggested that American women may be quietly proving him right. The study looked at the fertility intentions of over 41,000 women aged 15 to 44, finding that 50 percent of them were uncertain if they would have children in the future, even though they desired to be a mother. Researchers found that economic pressures, social shifts, and emotional uncertainty are driving a growing disconnect. The data also showed that uncertainty about having children isn't the same for all, and younger women are experiencing the biggest changes. Women aged 15 to 29 became increasingly unsure not only about whether they would have children, but also how strongly they felt about wanting them. In contrast, women aged 30 to 44 showed relatively stable levels of certainty over time. The data was collected from 2002 through 2019, which the team speculated revealed why US birth rates have been on a steady decline since the 2007 Great Recession. The fertility rate has decreased by 21 percent between 2007 and 2024. Musk, the billionaire father of 14 children, has often pointed to declining fertility as a sign that modern societies are forgetting how to survive. He previously said that low birth rates mean few workers, increased debt, strained healthcare and pension systems, and total social unrest. The US fertility rate was stable at about 2.0 children per woman in the 1990s and early 2000s, reaching a peak of 2.12 in 2007, statistics show. But the fertility rate steadily declined in the aftermath of the Great Recession, falling to 1.62 in 2023. Sarah Hayford, co-author of the study and professor of sociology at The Ohio State University, told Ohio State News: 'People's feelings about having children are complicated, and we found there are a lot of nuances. 'It suggests that there is no simple answer to the declining birth rate in the US.' The study used data from the National Survey of Family Growth, a federally funded survey conducted by the National Center for Health Statistics. Over the years studied, the team found that 62 percent of women said they intended to have a child and 35 percent did not intend to, with only a small percentage saying they didn't know. But up to half of the participants who intended to have children said they were only 'somewhat sure' or 'not sure at all' that they would realize their intention to have a child. The team found that women with higher incomes and education levels were more inclined to report 'very sure' that they would have children than those on the opposite side of the spectrum. Levels of certainty among women considering having children, showing the percentage who said they were not at all sure, somewhat sure, or very sure. Data includes confidence intervals and is grouped by parental status (b) and age (c). However, women with a bachelor's degree who gave that answer declined from 65 percent in 2014 to 54 percent in 2018. The data revealed another pattern holding women back from having children -the actual desire to be a mother. Up to 25 percent of childless women wouldn't be bothered if they never had kids. 'This not being bothered was especially high among younger women, and it increased over time among those who were younger,' Hayford said. 'They are open to different pathways and different kinds of lives. If they don't become parents for whatever reason, it doesn't seem that upsetting to many of them.' One commonly suggested reason for the declining birth rate is that young people today feel uncertain about the future, both of the country and the world, which may be causing them to delay or avoid having children. The team conducted a second study, surveying 3,696 people, which found that the more disassified they were with their own lives, the less likely they were to want a child. 'It was a bit of a surprise to us, but it was only their personal situation that mattered in whether they expected to have children,' Hayford said. 'It wasn't so much what was going on in society that predicted their fertility goals.'
