A new study used a light-based tomographic #3Dprinting approach to synthesize fine glass parts. The method should be flexible enough to provide a variety of high-quality glass parts for various applications.
COVER – A glass structure about 4.5 mm tall with features as small as 0.25 mm is 3D printed with microscale computed axial lithography followed by high-temperature sintering. The process enables the synthesis of highly transparent and inert glass parts with fine details, which are useful for a variety of applications.
In Nature this week: Climate pledges – fully realizing current promises could limit warming to just below 2 °C , but 1.5 °C is still out of reach. Browse the full issue here: https://t.co/eEMf9XL8lBpic.twitter.com/GuaC5pdolG
Even before COVID-19 increased the risks of cognitive impairments, it had been estimated that 152.8 million people globally would be living with dementia by 2050. Yet treatment for Alzheimer’s disease has hardly improved since it was discovered in 1901, notes neurologist and dementia specialist Sara Manning Peskin. Now, most clinical trials tackling dementia are “deeply rooted in molecular data”. Peskin’s powerful study — immersed in her patients’ stories — analyses neurology’s attempt to reach oncology’s molecular understanding.
The Insect Crisis
Oliver Milman Atlantic (2022)
Insect decline is obvious — but hard to quantify. Environmental journalist Oliver Milman suggests a drop of more than 90% in some places, in his vivid alarm call. The causes are unclear, but include habitat destruction by intensive farming, pesticide use and climate change. Insects’ “intricate dance” with Earth’s environment makes them crucial to human food supplies. We should learn to eat them, not meat, suggests Milman: that will help to save them by freeing farmland from crops needed to feed livestock.
Insulin — The Crooked Timber
Kersten T. Hall Oxford Univ. Press (2022)
Insulin was first used to treat human diabetes 100 years ago, after it was isolated by two medical scientists in 1921. Historian of science Kersten Hall describes this transformative event, together with insulin’s development as the first drug produced by genetic engineering and its lucrative exploitation — using a blend of profound research, lively writing and personal knowledge of diabetes. He argues that the history is a tale not of geniuses or saints, but rather one of “monstrous egos, toxic insecurities and bitter career rivalry”.
How to Solve a Crime
Angela Gallop Hodder & Stoughton (2022)
More than a century ago, criminologist Edmond Locard established forensic science on the principle that “every contact leaves a trace”. The field’s current sophistication and contribution to justice would be beyond his “wildest imaginings”, writes forensic scientist Angela Gallop. She tells gripping stories from her own and others’ experience, beginning with thirteenth-century Chinese investigator Sung Tz’u. He identified a farmer’s killer by asking fellow villagers to put their sickles on the ground; flies alighted on one blade bearing traces of blood.
The Sloth Lemur’s Song
Alison Richard William Collins (2022)
Anthropologist and conservationist Alison Richard has been absorbed by Madagascar for half a century. She writes that the country’s “animals and plants offer a wonderful array of rabbit holes down which a person fascinated by the natural world could disappear for a lifetime”. Why, for example, does its largest lemur sing spellbindingly across the treetops with its mate for many minutes? And what environmental conditions created the island’s unique — now disastrously threatened —
On this week’s show: A new measurement of the W boson could challenge physicists’ standard model, and an abundance of marine RNA viruses.
Staff Writer Adrian Cho joins host Sarah Crespi to discuss a new threat to the standard model of particle physics—a heavier than expected measurement of a fundamental particle called the W boson. They chat about how this measurement was taken, and what it means if it is right.
Next, Sarah talks about the microscopic denizens of Earth’s oceans with Ahmed Zayed, a research scientist in the department of microbiology at Ohio State University, Columbus. They talk about findings from a global survey of marine RNA viruses. The results double the number of known RNA viruses, suggesting new classifications will be needed to categorize all this viral diversity.
This week The World Economic Forum are highlighting 4 top stories – wheat shortages due to war, a female-led Mexican electric car brand, a robot dog guards Pompeii, and a plane fuelled by cooking oil.

Plane fueled by cooking oil The World Economic Forum is the International Organization for Public-Private Cooperation. The Forum engages the foremost political, business, cultural and other leaders of society to shape global, regional and industry agendas. We believe that progress happens by bringing together people from all walks of life who have the drive and the influence to make positive change.
Liberal centrists around the world should see Emmanuel Macron as a cautionary tale: one person alone cannot sustain the radical centre. Our cover explains why he still gets our vote, but with reservations https://t.co/AbrlQYRcOopic.twitter.com/8Uo8XaXPnY
