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.

World Economic Forum: Top Stories- June 17, 2023

World Economic Forum (June 17, 2023) – This week’s top stories of the week include:

0:15 How to solve the global rice shortage – Every day, more than half the world sits down to a plate of rice. A shortage could harm the food security of billions of the poorest people. But if scientists and farmers can solve this problem it would be great news for the climate, too

2:24 How El Niño will affect your weather – El Niño is a climate pattern in the Pacific Ocean and a new phase of it has just begun. Normally, Pacific ‘trade winds’ blow from east to west, pushing warm water away from South America towards Asia. Cold water rises in its place, regulating temperatures and drawing up nutrients for marine life from the ocean depths.

4:17 This fabric blocks mosquito bites – Researchers at Auburn University used a programmable 3D-knitting robot to create a weave that has a ‘chainmail effect’ at the microscopic level and which does not create openings as it bends. It also has enough holes for air flow to keep wearers cool in hot countries.

5:56 Indonesian poachers restore coral reefs – Marine scientist Syafyudin Yusuf is leading the efforts. Together, his team has restored 12 hectares of corals . Just 15 years ago, only 2% of the region’s original reefs remained undamaged. Local fishers used explosives and chemicals to stun or kill fish, making them easier to catch. “We needed to live and survive, but the chances of getting a decent job aren’t good, and the only job we knew of was that, that’s how we began bombing the reefs.”

nature Magazine – May 18, 2023 issue: The cover shows an artist’s impression of two male mammoths fighting. During episodes of musth, adult male elephants undergo periods of elevated testosterone levels associated with aggression and competition for mating. In this week’s issue, Michael Cherney and his colleagues show that male woolly mammoths (Mammuthus primigenius) experienced similar episodes of musth. 

The ocean is hotter than ever: what happens next?

Record temperature combined with an anticipated El Niño could devastate marine life and increase the chances of extreme weather.

The global ocean hit a new record temperature of 21.1 ºC in early April, 0.1 ºC higher than the last record in March 2016. Although striking, the figure (see ‘How the ocean is warming’) is in line with the ocean warming anticipated from climate change. What is remarkable is its occurrence ahead of — rather than during — the El Niño climate event that is expected to bring warmer, wetter weather to the eastern Pacific region later this year.

For chemists, the AI revolution has yet to happen

Machine-learning systems in chemistry need accurate and accessible training data. Until they get it, they won’t achieve their potential.

Many people are expressing fears that artificial intelligence (AI) has gone too far — or risks doing so. Take Geoffrey Hinton, a prominent figure in AI, who recently resigned from his position at Google, citing the desire to speak out about the technology’s potential risks to society and human well-being.
