The climate crisis is threatening the future of the world's most popular fruit, as almost two-thirds of banana-growing areas in Latin America and the Caribbean may no longer be suitable for growing the fruit by 2080, new research has found. From a report: Rising temperatures, extreme weather and climate-related pests are pummeling banana-growing countries such as Guatemala, Costa Rica and Colombia, reducing yields and devastating rural communities across the region, according to Christian Aid's new report, Going Bananas: How Climate Change Threatens the World's Favourite Fruit. Bananas are the world's most consumed fruit -- and the fourth most important food crop globally, after wheat, rice and maize. About 80% of bananas grown globally are for local consumption, and more than 400 million people rely on the fruit for 15% to 27% of their daily calories.

Western Digital has made a strategic investment in German startup Cerabyte, a company developing nearly indestructible ceramic-based data storage technology. The partnership aims to accelerate commercialization of Cerabyte's ceramic-on-glass material, which the company claims can preserve data for 5,000 years. Cerabyte recently demonstrated its technology's resilience by boiling storage devices in salt water and subjecting them to oven-level heat. The company states its ceramic storage withstands fire, moisture, UV light, radiation, corrosion, and EMP bursts. Beyond durability, Cerabyte aims to enable massive capacity increases as the industry moves toward what it calls the "Yottabyte era," while targeting storage costs below $1 per TB by 2030.

Apple is weighing price increases for its fall iPhone lineup, a step it is seeking to couple with new features and design changes, according to WSJ, which cited people familiar with the matter. From the report: The company is determined to avoid any scenario in which it appears to attribute price increases to U.S. tariffs on goods from China, where most Apple devices are assembled, the people said. The U.S. and China agreed Monday to suspend most of the tariffs they had imposed on each other in a tit-for-tat trade war.

The United States and China said Monday they reached an agreement to temporarily reduce the tariffs [non-paywalled source] they have imposed on each other in an attempt to defuse the trade war threatening the world's two largest economies. From a report: In a joint statement, the countries said they would suspend their respective tariffs for 90 days while they negotiate. Under the agreement, the United States would reduce the tariff on Chinese imports to 30 percent from its current 145 percent, while China would lower its import duty on American goods to 10 percent from 125 percent. "We concluded that we have a shared interest," said Treasury Secretary Scott Bessent at a news conference in Geneva where U.S. and Chinese officials met over the weekend. "The consensus from both delegations is that neither side wanted a decoupling," he said. The agreement breaks an impasse that had brought trade between China and the United States to a halt. Many American businesses had suspended orders, holding out hope that the two countries could strike a deal to bring down the tariff rates while raising the spectre of price increases.

Evidence is mounting for "a vast reservoir of liquid water" on Mars, according to a new article by Australian National University professor Hrvoje TkalÄiÄ and geophysics associate professor Weijia Sun from the Chinese Academy of Geological Sciences, announcing their recently published paper. "Using seismic data from NASA's InSight mission, we uncovered evidence that the seismic waves slow down in a layer between 5.4 and 8 kilometres below the surface, which could be because of the presence of liquid water at these depths." Mars is covered in traces of ancient bodies of water. But the puzzle of exactly where it all went when the planet turned cold and dry has long intrigued scientists... Billions of years ago, during the Noachian and Hesperian periods (4.1 billion to 3 billion years ago), rivers carved valleys and lakes shimmered. As Mars' magnetic field faded and its atmosphere thinned, most surface water vanished. Some escaped to space, some froze in polar caps, and some was trapped in minerals, where it remains today. But evaporation, freezing and rocks can't quite account for all the water that must have covered Mars in the distant past. Calculations suggest the "missing" water is enough to cover the planet in an ocean at least 700 metres deep, and perhaps up to 900 metres deep. One hypothesis has been that the missing water seeped into the crust. Mars was heavily bombarded by meteorites during the Noachian period, which may have formed fractures that channelled water underground. Deep beneath the surface, warmer temperatures would keep the water in a liquid state — unlike the frozen layers nearer the surface. In 2018, NASA's InSight lander touched down on Mars to listen to the planet's interior with a super-sensitive seismometer. By studying a particular kind of vibration called "shear waves", we found a significant underground anomaly: a layer between 5.4 and 8 kilometres down where these vibrations move more slowly. This "low-velocity layer" is most likely highly porous rock filled with liquid water, like a saturated sponge. Something like Earth's aquifers, where groundwater seeps into rock pores. We calculated the "aquifer layer" on Mars could hold enough water to cover the planet in a global ocean 520-780m deep. InSight's seismometer captured vibrations between the crust of Mars and its lower layers from two meteorite impacts in 2021 and a Marsquake in 2022. "These signatures let us pinpoint boundaries where rock changes, revealing the water-soaked layer 5.4 to 8 kilometres deep." It's an exciting possibility. "Purified, it could provide drinking water, oxygen, or fuel for rockets." And since microbes thrives on earth in deep rocks filled with water, "Could similar life, perhaps relics of ancient Martian ecosystems, persist in these reservoirs?"

Business Insider tells the story in three bullet points: - Big Tech companies depend on content made by others to train their AI models. - Some of those creators say using their work to train AI is copyright infringement. - The U.S. Copyright Office just published a report that indicates it may agree. The office released on Friday its latest in a series of reports exploring copyright laws and artificial intelligence. The report addresses whether the copyrighted content AI companies use to train their AI models qualifies under the fair use doctrine. AI companies are probably not going to like what they read... AI execs argue they haven't violated copyright laws because the training falls under fair use. According to the U.S. Copyright Office's new report, however, it's not that simple. "Although it is not possible to prejudge the result in any particular case, precedent supports the following general observations," the office said. "Various uses of copyrighted works in AI training are likely to be transformative. The extent to which they are fair, however, will depend on what works were used, from what source, for what purpose, and with what controls on the outputs — all of which can affect the market." The office made a distinction between AI models for research and commercial AI models. "When a model is deployed for purposes such as analysis or research — the types of uses that are critical to international competitiveness — the outputs are unlikely to substitute for expressive works used in training," the office said. "But making commercial use of vast troves of copyrighted works to produce expressive content that competes with them in existing markets, especially where this is accomplished through illegal access, goes beyond established fair use boundaries." The report says outputs "substantially similar to copyrighted works in the dataset" are less likely to be considered transformative than when the purpose "is to deploy it for research, or in a closed system that constrains it to a non-substitutive task." "A day after the office released the report, President Donald Trump fired its director, Shira Perlmutter, a spokesperson told Business Insider."
