Nature Reviews: Top New Science Books – May 2023

nature Magazine Science Book Reviews – May 15, 2023: Prejudice in technology, and the necessity of time. Andrew Robinson reviews five of the best science picks.

More Than a Glitch

Meredith Broussard – MIT Press (2023)

An artificial-intelligence (AI) ‘glitch’ is a problem neither expected nor consequential. Bias, by contrast, is baked in and disastrous, argues data scientist Meredith Broussard, one of very few Black women in this field, who focuses on AI and journalism. “Tech is racist and sexist and ableist because the world is so,” she says. Vivid examples in her disturbing book include that of a man arrested by US police using facial-recognition technology — purely because both he and the suspect in a blurry surveillance photo were Black.

Assyria

Eckart Frahm – Basic (2023)

The world’s first empire flourished in Assyria in the eighth and seventh centuries bc, and has long been seen as the epitome of barbarism. But, as Assyriologist Eckart Frahm reveals in his deeply informed, challenging history, Assyria produced many features of the modern world. Its innovations included long-distance trade, sophisticated communications networks, mass deportations and widespread political surveillance. Unlike most later empires, he writes, it was at least honest in its “open celebration of plunder, torture, and murder”.

Hands of Time

Rebecca Struthers –  Hodder & Stoughton (2023)

‘Time’ is “the most commonly used noun” in English, according to Rebecca Struthers, the first professional watchmaker in the United Kingdom to earn a PhD in horology. Each chapter of her exquisitely crafted history explores a pivotal moment in watchmaking from the past 500 years. Mechanical timekeepers, she argues, have influenced human culture as much as the printing press. Imagine trying to catch a train by depending on the Sun’s position, or to perform an organ transplant without measuring the patient’s heart rate precisely.

The Deep Ocean

Michael Vecchione et al. Princeton Univ. Press (2023)

“For most people, the deep ocean is out of sight and out of mind,” write three zoologists and an oceanographer. The zone starts where penetration of sunlight can no longer support photosynthesis, about 200 metres down. This guidebook dissipates ignorance with superb colour photographs of astonishing organisms, accompanied by detailed captions and brief essays. For example, the vampire squid (Vampyroteuthis infernalis) is neither vampire nor squid, but was so named because its black ‘cloak’ reminded scientists of Dracula.

Tenacious Beasts

Christopher J. Preston –  MIT Press (2023)

Humans and domestic animals make up 96% of the mass of the world’s mammals. The outlook for wildlife “remains dire”, writes philosopher Christopher Preston. But he describes signs of hope in his well-travelled, thoughtful study of recoveries. Populations of humpback whales in the western Indian Ocean have surged since the mid-twentieth century; those of Californian black bears have quadrupled in a few decades. He visits farmland, prairie, river, forest and ocean, exploring why only certain species are recovering.

Volume 617 Issue 7960

nature Magazine – May 11, 2023 issue: The human reference genome has been the backbone of human genomics since the release of the draft sequence in 2001. But it has its limitations: one genome cannot hope to capture the diversity of the human species. In this week’s issue, the Human Pangenome Reference Consortium presents the first draft human pangenome, which combines genetic material from 47 genetically diverse individuals to provide a more complete picture of the human genome.

nature Magazine – May 4, 2023 issue: As stars evolve, they expand and so will engulf planets in close orbit around them. This planetary catastrophe is expected to generate powerful luminous ejections of mass from the star, although this has not been observed directly.

Is the world ready for ChatGPT therapists?

The current landscape of mobile mental-health apps is the result of a 70-year search to automate therapy. Now, advanced AIs pose fresh ethical questions.

Since 2015, Koko, a mobile mental-health app, has tried to provide crowdsourced support for people in need. Text the app to say that you’re feeling guilty about a work issue, and an empathetic response will come through in a few minutes — clumsy perhaps, but unmistakably human — to suggest some positive coping strategies.

Fish on dry land hint at why we blink

Insights from mudskippers suggest that blinking is an adaptation to emerging from the sea.

Massive mosquito factory in Brazil aims to halt dengue

Facility will produce up to five billion bacteria-infected mosquitoes per year

The non-profit World Mosquito Program (WMP) has announced that it will release modified mosquitoes in many of Brazil’s urban areas over the next 10 years, with the aim of protecting up to 70 million people from diseases such as dengue. Researchers have tested the release of this type of mosquito — which carries a Wolbachia bacterium that stops the insect from transmitting viruses — in select cities in countries such as Australia, Brazil, Colombia, Indonesia and Vietnam. But this will be the first time that the technology is dispersed nationwide.

Volume 616 Issue 7957, 20 April 2023

nature Magazine – April 20, 2023 issue: Although currently there is no known threat to Earth from asteroids, strategies to protect the planet from a collision are being explored. On 26 September 2022, NASA and the Johns Hopkins Applied Physics Laboratory successfully tested one such approach: the Double Asteroid Redirection Test (DART) spacecraft was deliberately crashed into Dimorphos, a moon orbiting the small asteroid Didymos, resulting in a change in the moon’s orbit.

Book Reviews: ‘On The Origin Of Time – Stephen Hawking’s Final Theory’

On the Origin of Time

Like his mentor and colleague Stephen Hawking, Thomas Hertog has never shied away from being ambitious in theorizing about the universe. This sweeping book provides an accessible overview of both what we know about cosmology, and some audacious ideas for moving into the unknown. It is an introduction to Hawking’s final theory, but also a glimpse into even grander theories yet to come.

nature Magazine – April 13, 2023 issue: Octopuses use chemotactile receptors (CRs) in the suckers on their arms to ‘taste by touch’ as they explore their sea-floor environment. These proteins evolved from neurotransmitter receptors to allow octopuses to detect poorly soluble natural products on contact.

nature Magazine – April 6, 2023 issue: In 1947, Isaac Berenblum proposed that the development of cancer was a two-stage process: the first step introduces mutations into healthy cells, the second then promotes tumour growth through tissue inflammation. In this week’s issue, Charles Swanton and his colleagues investigate the role of particulate matter in prompting the development of non-small-cell lung cancers and find that cancer initiation in response to pollution conforms to Berenblum’s model. 

Carbon dioxide removal is not a current climate solution — we need to change the narrative

Volume 615 Issue 7954

nature Magazine – March 30, 2023 issue: Medieval people on the Swahili coast of East Africa were among the first sub-Saharan people to practise Islam. David Reich, Chapurukha Kusimba and colleagues sequenced DNA from 80 individuals buried in six medieval and early modern coastal Swahili stone towns, dating between 1250 and 1800. Their analysis shows that African women and Asian men began mixing along the East African coast before the year 1000, and that the earliest Asian migrants were of largely Persian origin.

nature Magazine – March 23, 2023 issue: One of the main hurdles to putting autonomous cars on the road is how to ensure the reliability of the artificial intelligence that replaces the human driver. Evaluating the safety of an AI driver to the level of a human in a naturalistic environment would require testing across hundreds of millions of miles — something that is clearly impractical.
