Study of the influence of hard interlayers on seismic parameters via shaking table tests - Nature

We’re sharing this article early to provide faster access to peer-reviewed, accepted research. It is citable and carries a permanent DOI. This version is subject to further edits and will be replaced automatically by the final Version of Record. All legal disclaimers apply. AbstractAccording to the third theorem of similarity, a layered physical model was established using two types of materials with different shear stiffnesses. This model was used to represent the prototype in shaking table tests, and the influences of the burial depth and thickness of the hard interlayer on the amplification factor and on the characteristic parameters of the response spectrum were analysed and studied. The study revealed the following: (1) The influence trends of the burial depth and thickness of the hard interlayer on the amplification factor and on the characteristic period of the response spectrum obtained from the shaking table tests were found to be consistent with those obtained from a one-dimensional equivalent linearization calculation. This comparison serves as a verification of the experimental results rather than as an independent conclusion.

Electronic opacity in double bilayer graphene junctions - Nature

We’re sharing this article early to provide faster access to peer-reviewed, accepted research. It is citable and carries a permanent DOI. This version is subject to further edits and will be replaced automatically by the final Version of Record. All legal disclaimers apply. AbstractIn this paper, we examine the transmission probability through a symmetric double bilayer-graphene junction modulated by Fano-type interference. At oblique incidence, two trajectories generated by Fano resonances and a quasi-bound well state are combined to generate perfect Fano interference resulting in null electron transmission. Interestingly, the transmission can be changed between normal and anomalous simply by adjusting the relative phase of the Fano resonances due to the appropriate modulation of the incidence angle, height of potential, and barrier and well width. This phenomenon is similar to electromagnetically induced absorption or to phase control of light propagation in quantum wells via Fano interference.

Author Correction: Ecdysone signaling-induced dumpless1 expression controls nurse cell dumping in Drosophila oogenesis - Nature

volume 17, Article number: 10957 (2026) Cite this article Correction to: Nature Communications https://doi.org/10.1038/s41467-025-63973-3, published online 7 October 2025Following the publication of this article, we identified an error in the Source Data file accompanying the paper. In the worksheet for Fig. 8o, both the control and the integrin βPS RNAi experimental group data columns were incorrectly pasted during data compilation—they were inadvertently populated with a subset of measurements (52 values each) that had been extracted from the 7-day samples of the CG12942 overexpression experiment (Fig. 3n), rather than the correct data from the independent integrin βPS knockdown rescue experiment. We have now retrieved the original experimental images and measurement records for the integrin βPS RNAi experiment (including both control and integrin βPS RNAi groups). Reanalysis using the correct data confirms that the conclusion remains unchanged: knockdown of integrin βPS in SFCs partially rescues the egg length defects in dumpless1 mutant females.

Your aging brain may be trading memory for something more valuable - Science Daily

Growing older is often associated with memory loss and declining mental abilities. However, scientists are questioning whether these changes tell the whole story. Rather than simply becoming less capable, the brain may be adapting to a new stage of life in which accumulated knowledge, wisdom, and understanding become more important than remembering every detail. Researchers at the University of Arizona have proposed a different way of understanding cognitive aging. Drawing on findings from molecular biology and brain imaging, they suggest that the changes occurring in older brains may reflect a natural stage of human development rather than deterioration alone. Their work, published in Perspectives on Psychological Science, offers a new perspective on why thinking and memory change with age.

Chinese team invents 1-gram microscope for precise neural detection - Xinhua

A mouse wearing Airscope explores in a habitat built in a laboratory at Tsinghua University in Beijing, capital of China, Oct. 19, 2026. (Xinhua/Wei Mengjia)BEIJING, Oct. 20 (Xinhua) -- Chinese scientists have developed a wireless microscope weighing only 1 gram that can record neural activity in the mouse cerebral cortex with single-cell resolution in natural environments. Named Airscope, the device was developed by a team led by Dai Qionghai, an academician of the Chinese Academy of Engineering and a professor at Tsinghua University, in collaboration with researchers from other institutions. Details of the achievement were published in Nature on Monday. Dai said the microscope provides a new tool for understanding the neural basis of intelligence and will drive optical brain-computer interfaces toward more precise neural detection. Its future applications may expand beyond neuroscience to fields such as immunity and oncology, enabling complete tracking of disease processes, Dai added.

Copper Needs $332 Billion in New Mines to Avoid Deficit, BloombergNEF Says - Crude Oil Prices Today | OilPrice.com

While nine out of ten key energy transition metals are back on track to deliver sufficient supply by 2050, a total of $332 billion of investment is needed in new copper mines to avoid a looming copper deficit that could slow electrification, BloombergNEF said in its Transition Metals Outlook 2026 on Tuesday. In recent years, supply of key energy transition metals has improved considerably, with the exception of copper, which is still expected to see a shortfall through 2050, unless billions of dollars are invested in new supply. Lithium, graphite, cobalt, aluminum, nickel, manganese, steel, platinum, and palladium are all expected to have sufficient long-term supply capacity to support electrification through 2050, as global shortages have eased significantly, BNEF says.  However, copper remains the major exception in this group of critical metals. BNEF expects a supply deficit in the global copper markets to begin in 2028 and widen to as much as 20 million metric tons by 2050. This deficit would be equivalent to 44% of projected global demand. Meanwhile, global copper demand is expected to jump by 61% between 2026 and 2050, reaching nearly 46 million tons.

‘Oh God, I can’t bear it’: Judi Dench says Cats film was ‘a waste of goodwill and talent’

Dame Judi Dench has long made her feelings clear about Cats, the doomed 2019 adaptation of the Andrew Lloyd Webber musical. In an interview the year after release, she said she had so far declined to watch the movie – in which she played wise moggy Old Deuteronomy – and described the orange fur coat she had to wear as looking like “five foxes fucking on my back”. In her forthcoming memoir, Is It Too Late to Make a Run for It? Dench reflects further on her involvement in the movie, which was universally panned and whose director, Tom Hooper, has not made a film since. “Oh God, I can’t bear it,” she writes in the book, “and [Lloyd Webber] had waited so long for it to be made. What a waste of all that goodwill and talent. “I understand the critics were rather hostile to the film. I never saw the final cut so I can’t judge. All I’ll say is nobody sets out to give a poor performance or make a bad film.

Qualcomm to cut jobs globally in ‘performance-focused’ layoffs, internal memo shows

Open this photo in gallery:Visitors stand at the Qualcomm kiosk during the AI Impact Summit, in New Delhi, India, in February. Bhawika Chhabra/ReutersQualcomm Inc. QCOM-Q will cut jobs globally in a “performance-focused reduction” following its annual employee reviews, CEO Cristiano Amon told staff in a memo on Monday reviewed by Reuters, with notifications set to begin in November. The cuts are part of an effort to build “a stronger performance culture” and address situations where the company “has consistently fallen short of expectations,” Amon said. The memo did not say how many jobs would be affected, and Reuters could not immediately determine the scale of the cuts. Qualcomm did not immediately respond to a request for comment. It had about 52,000 employees globally as of September last year, most of them full-time. Its financial year typically ends in late September. One of the world’s biggest smartphone chip makers, Qualcomm has been hit this year by a slump in consumer electronics sales as soaring memory prices weigh on demand in key markets.
