Scientists say we’ve been treating Alzheimer’s all wrong

  Openen als pagina
Alzheimer’s isn’t just one problem—it’s a tangled mix of biology, aging, and overall health. That’s why drugs targeting a single factor have fallen short, even as new treatments show modest benefits. Scientists are now pushing toward multi-pronged strategies, from gene editing to brain-cell rejuvenation and gut health interventions. The goal: stop treating Alzheimer’s as one disease and start tackling it as a complex system.

Gravitational waves may be hidden in the light atoms emit

  Openen als pagina
Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The effect doesn’t change how much light atoms emit, which is why it’s gone unnoticed until now. If confirmed, this approach could lead to ultra-compact detectors using cold-atom systems.

This superconductivity dies then comes back to life

  Openen als pagina
A strange new kind of superconductivity has been uncovered in uranium ditelluride (UTe2), where electricity flows with zero resistance—but only under extremely strong magnetic fields that should normally destroy it. Even more surprising, the superconductivity disappears at first and then dramatically reappears at even higher fields, earning it the nickname the “Lazarus phase.”

These cheap solar cells work better because they’re flawed

  Openen als pagina
Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric charges efficiently. Using a novel imaging method, they revealed hidden structures acting like charge “highways.” This insight could unlock even more powerful, low-cost solar cells.

Paleontologists have examined 289-million-year-old specimens of the early reptile Captorhinus aguti that preserve a covering of three-dimensional skin, a complete shoulder girdle and ribcage with cartilages, and protein remnants that predate the previous oldest-known example by nearly 100 million years.

Pohlsepia mazonensis, a cephalopod species first described in 2000 from a 300-million-year-old specimen and featured in the Guinness Book of Records as the world’s oldest octopus, has been reclassified as a distant relative of nautiluses, reshaping paleontologists’ timeline for when octopuses first evolved.

The Lancet

[Editorial] The future of preconception health

  Openen als pagina
In 2018, the first Lancet Series on preconception health, led by Judith Stephenson, argued that the health and nutrition of both men and women before conception is important not only for pregnancy outcomes but also for the lifelong health of their children. We called for a campaign built on a three-pronged approach that recognised the biological, individual, and public health dimensions of preconception, taking a life course view. 8 years on, that call has been only partially answered. The Series helped to broaden the concept of preconception health, beyond a narrow focus on women's health before pregnancy, to encompass the health and wellbeing of women, men, and couples before conception.

[Comment] Liver disease: screening for the elusive adversary

  Openen als pagina
It is almost 60 years since the original Wilson and Jungner1 criteria for evaluating population screening programmes were published, with the tenets presented having stood the test of time. Liver disease is a curious case in which to apply these principles. Supporting the rationale for screening is the long-asymptomatic phase of disease and the very poor outcomes for late presentations. However, there is no consensus about who has a clinically relevant disease and who gets treatment, and the most accurate non-invasive testing approach undermines these justifications.

[Comment] Offline: World war—is it too late?

As you drive out of Geneva towards the airport, along the Rue de Lausanne, you pass a long, flat, ochre-brick building lying between the road and the lake: the World Trade Organization. Fenced off with formidable security, the headquarters of a body charged with administering a rules-based international trade order does not exude welcoming warmth. But it does give a hint of humanity by naming itself on the pillars erected around the building—the Centre William Rappard. Who was William Rappard? He was born in New York in 1883, but moved to Switzerland when he was 17 years old.

From teeth to thorns: Coincidences shape the universal form of nature's pointed tips

  Openen als pagina
We thought it was evolution, but an experiment with pencils shows that tips like teeth and thorns may owe their rounded shape to mechanical wear. Most of us have been stung by a bee, bitten by an animal, or scratched by a thorny bush. But very few of us have probably taken a close look at nature's painful, pointed tips.

SNIPE bacterial defense system shreds phage DNA before infection can begin

  Openen als pagina
What if the Trojan horse had been pulled to pieces, revealing the ruse and fending off the invasion, just as it entered the gates of Troy? That's an apt description of a newly characterized bacterial defense system that chops up foreign DNA. Bacteria and the viruses that infect them, bacteriophages—phages for short—are ceaselessly at odds, with bacteria developing methods to protect themselves against phages that are constantly striving to overcome those safeguards.

Open letter urges Labor to reverse JRG scheme, introduced by Coalition in 2021, as cost of humanities degrees reaches more than $50,000

Tim Winton knows what it’s like to be the first in a family to go to university – “what a breakthrough that is, the kind of opportunities it provides”.

It was at the Western Australian Institute of Technology, studying arts, that he wrote his first novel, An Open Swimmer, launching a four-decade writing career.

Large language models that power AI should be publicly owned | Letter

  Openen als pagina

The future of public knowledge rests on building open-access LLMs driven by ethics rather than profit, writes Prof Dr Matteo Valleriani

Large language models (LLMs) have rapidly entered the landscape of historical research. Their capacity to process, annotate and generate texts is transforming scholarly workflows. Yet historians are uniquely positioned to ask a deeper question – who owns the tools that shape our understanding of the past?

Most powerful LLMs today are developed by private companies. While their investments are significant, their goals – focused on profit, platform growth or intellectual property control – rarely align with the values of historical scholarship: transparency, reproducibility, accessibility and cultural diversity.

Humanities teaching will have to adapt to AI | Letter

Jim Endersby recalls how maths teachers responded to the arrival of cheap pocket calculators in the 1970s and likens it to current fears of AI use by university students

I agree with Prof Andrew Moran and Dr Ben Wilkinson (Letters, 2 March) that cheap and easy‐to‐use AI tools create problems for universities, but the reactions of many academics to these new developments remind me of the way some people responded to the arrival of cheap pocket calculators in the 1970s.

Reports of the imminent death of maths teaching in schools proved exaggerated. Maths teachers had to adapt, not least to teach students the longstanding rule “garbage in, garbage out”; if students had no idea of the fundamental principles and ideas behind maths, they would not realise their answer was meaningless. Today’s humanities teachers are going to have to adapt in similar ways.

The deep cultural cost of British university job cuts | Letters

  Openen als pagina

Arts and humanities are being hit hardest by cuts in higher education, write Prof Thea Pitman and Prof Emma Cayley, and Dr Ronan McLaverty-Head and another letter writer comment on cuts at Cardiff and another Russell Group university

In response to the shocking news predicting up to 10,000 imminent job losses across the UK higher education sector (Quarter of leading UK universities cutting staff due to budget shortfalls, 1 February), we write to flag up a fact that the article largely misses: the degree to which arts and humanities subjects are bearing the brunt of these cuts.

While the article singles out the loss of nursing courses at Cardiff University and the closure of chemistry courses across the country, it mentions the humanities just once in passing. Last week it was ancient history, modern languages, music, religion and theology at Cardiff University. Not so long ago, it was subjects including English, history, music and theatre at Goldsmiths, and art history, music, philosophy and religious studies at the University of Kent, to name just two. And with each passing week more arts and humanities courses and departments are cut.

The Guardian view on humanities in universities: closing English Literature courses signals a crisis

  Openen als pagina

With degrees disappearing and reading rates plummeting, the arts face a critical moment in education and culture

The announcement that Canterbury Christ Church University in Kent is to stop offering English literature degrees has set several hares running, most of them in the wrong direction. The university said in effect that hardly anyone wanted to study English literature at degree level any more and the course was therefore no longer viable. If you can’t do EngLit in the city of Chaucer and Marlowe, where can you do it?

Canterbury’s tale is a familiar one. EngLit is in wholesale retreat at A level, with numbers down from 83,000 in 2013 to 54,000 in 2023, and there has been a decline at university, too, over the past decade, though statistics are disputed because the subject gets studied at degree level in many guises, including creative writing and linguistics. Overall, humanities subjects seem to be losing their appeal, with only 38% of students taking a course in 2021/22, down from nearly 60% between 2003/4 and 2015/16.
