nature Magazine – September 7, 2023 issue:  In this week’s issue, Christopher Doughty and his colleagues reveal that a small percentage of leaves in tropical forest tree canopies might be approaching a critical temperature of 46.7 °C, above which photosynthesis begins to fail.

How would room-temperature superconductors change science?

The prized materials could be transformative for research — but only if they have other essential qualities.

The wave of excitement caused by LK-99 — the purple crystal that was going to change the world — has now died down after studies showed it wasn’t a superconductor. But a question remains: would a true room-temperature superconductor be revolutionary?

With the arrival of El Niño, prepare for stronger marine heatwaves

Record-high ocean temperatures, combined with a confluence of extreme climate and weather patterns, are pushing the world into uncharted waters. Researchers must help communities to plan how best to reduce the risks.

Oceans are warming up, and dangerously so. Since April this year, the average global sea surface temperature has been unusually high and rising; by August, oceans in the Northern Hemisphere had reached record-high temperatures, even surpassing 38 °C in one area around Florida.

India’s Moon landing is a stellar achievement — and a win for science

A mother along with her daughter arrives to watch landing of Chandrayaan-3's Vikram lander on Moon.

When Chandrayaan-3 touched down, India pulled off a huge win for its own space programme and for international efforts to understand the Moon.

It’s hard to land on the Moon and keep your spacecraft intact. Just days ago, Russia’s Luna-25 mission crashed, dashing hopes for the country’s first trip to the Moon since 1976, when it was part of the Soviet Union. In April, a private Japanese effort also crash-landed on the lunar surface. That is one of the reasons the successful landing of the Chandrayaan-3 mission by the Indian Space Research Organisation (ISRO) is so special.

The causes of wildfires are clear. How they burn through communities is not

Events in Hawaii show how much we have to learn about wildfire spread — but simple research steps can help to build resilience.

An aerial photo from August 10 shows destroyed buildings burned to the ground due to wildfires in western Maui, Hawaii.

Driven by drought, high winds and extreme heat, fires in recent years have caused destruction and losses on a scale bigger than anyone is used to. The average annual global cost of wildfires is around US$50 billion, the World Economic Forum said in January. And by the end of the century, climate change might make catastrophic conflagrations 50% more common, according to the United Nations Environment Programme. Given the surge in urban development in and near forested areas, something has to be done to protect communities. As Maui’s experience shows, little is in place.

Want a sustainable future? Then look to the world’s cities

In a rapidly urbanizing world, what happens in cities matters — and sustainability success stories show what can be achieved when researchers and policymakers work together.

A person rides a bicycle as heat waves shimmer, causing visual distortion, as people walk in the 'The Zone', Phoenix'.

More than half of the world’s population lives in cities, and that proportion is set to grow. By 2050, another two billion people will be urban dwellers, the United Nations estimates. Cities lie at the nexus of all aspects of human development, from building thriving economies to coping with climate change.

Earth’s hottest month: these charts show what happened in July and what comes next

A damaged saguaro cactus stands with a recently fallen arm resting on the sidewalk in Mesa, Arizona.

The planet has warmed 1.2 ºC on average, but that’s enough to produce big extremes.

From wilting saguaros in Arizona and hot-tub-like temperatures off the coast of Florida to increased heat-related hospitalizations in Europe and agricultural losses in China, last month felt unusually hot. It was: several teams have now confirmed that July 2023 was the hottest month in recorded history. And there’s more to come.

July is typically the hottest month of the year, and this July shattered records going back as far as 1850 by around 0.25 °C. Overall, the average global temperature was 1.54 °C above the preindustrial average for July, according to Berkeley Earth, a non-profit group in California that is one of several organizations tracking global warming. It’s a seemingly small increase, but what many people across the world actually experienced was a bout of long and often brutal heat waves.

The conversational AI-powered chatbots that have come to Internet search engines, such as Google’s Bard and Microsoft’s Bing, look increasingly set to change scientific search, too. On 1 August, Dutch publishing giant Elsevier released a ChatGPT-like artificial-intelligence (AI) interface for some users of its Scopus database, and British firm Digital Science announced a closed trial of an AI large language model (LLM) assistant for its Dimensions database. Meanwhile, US firm Clarivate says it’s working on bringing LLMs to its Web of Science database.

Nature Reviews: Top New Science Books – AUG 2023

nature Magazine Science Book Reviews – August 4, 2023: The bitter-sweet history of sugar, and the marvels of measurement. Andrew Robinson reviews five of the best science picks.

Life and Afterlife in Ancient China

By Jessica Rawson 

When constructing monumental tombs thousands of years ago, “the Egyptians built up” — with their pyramids — whereas “the Chinese built down”, writes sinologist Jessica Rawson. The geology of China’s dry Loess Plateau permitted the excavation of shafts more than 10 metres deep. These tombs were filled with objects for the afterlife. Rawson’s majestic history explores 11 such monuments and one large sacrificial deposit, dating from 5,000 years ago to the third century bc, with the First Emperor’s protective Terracotta Army.

The World of Sugar

Ulbe Bosma 

Sugar’s societal dominance is a recent development. Granulated sugar was eaten from the sixth century bc in India, but refined sugar became widely available in Europe only in the nineteenth century. Its history is both a story of progress and a bitter-sweet tale of “exploitation, racism, obesity, and environmental destruction”, writes historian Ulbe Bosma in his authoritative, highly readable study — the first to be truly global. Of 12.5 million Africans kidnapped in the Atlantic slave trade, between half and two-thirds were enslaved on sugar plantations.

The Seven Measures of the World

Piero Martin (transl. Gregory Conti) 

The great civilizations of the ancient world could use precise measurements — witness the Egyptian pyramids. But their units differed. Not until 1960 was the international system of measurement (SI) introduced, defining the metre, second, kilogram, ampere, kelvin and candela — then the mole in 1971. Each gets a chapter in this concise, anecdotal history by experimental physicist Piero Martin. He stresses the subjective aspect of measurement, such as the idea that the quality of scientific publications matters more than their quantity.

Unearthing the Underworld

By Ken McNamara 

Earth scientist Ken McNamara focuses on palaeontology and evolution. His appealing book about rocks and their lessons — illustrated with fine photographs of fossils — leaves aside igneous and metamorphic rocks, and the wonders of mineralogy. It concentrates instead on sedimentary rocks: mudstones, siltstones, sandstones and limestones, scattered over three-quarters of Earth’s surface in “endless piles”. As he jokily advises: “Ignore rocks at your peril.” But then surely continental drift deserved proper discussion?

In Light-Years There’s No Hurry

Marjolijn van Heemstra (transl. Jonathan Reeder)

Dutch space reporter Marjolijn van Heemstra is also a poet, novelist and playwright. This translation of her highly personal meditation on the Universe reflects lyrically on the fact that the atmosphere “signifies a boundary”, whereas space “appeals to our notion of boundlessness”. She notes a growing difference of opinion between those who see space exploration as irresponsible because our planet is in deep trouble — environmental and otherwise — and those who regard space as a potential refuge from Earth.

nature Magazine – August 3, 2023 issue: Lithium-metal batteries promise to charge rapidly and to hold more energy than batteries based on lithium ions. Recharging these batteries requires lithium metal to be reformed at the anode, but this process is affected by the battery’s electrolyte and current collector, which causes the shape of the lithium deposits to vary unpredictably, impairing the battery’s performance.

The dawn of a new geological epoch is recorded in the contaminated sediment at the bottom of Crawford Lake in Canada.

The official marker for the start of a new Anthropocene epoch should be a small Canadian lake whose sediments capture chemical traces of the fallout from nuclear bombs and other forms of environmental degradation. That’s a proposal out today from researchers who have spent 14 years debating when and how humanity began altering the planet.
