Earth's Population Has Surpassed The Planet's Capacity, Study Suggests - ScienceAlert

NEED TO KNOWThe Jeddah Tower has surpassed the height of New York City's Central Park TowerThe Saudi Arabia skyscraper, which could be completed by August 2028, is planned to reach 3,280 feetThe structure will contain residential, commercial and office spaces, plus a luxury hotel and observation deckThe Jeddah Tower has reached another major milestone. John Peronto, the engineer and project manager for the future tallest building in the world, located in Jeddah, Saudi Arabia, told Newsweek on Tuesday, Oct. 6 that the tower "has now surpassed the world's tallest all-residential tower, Central Park Tower, and is nearing 500 meters [over 1,640 feet]. "Central Park Tower, located in New York City, stands at 1,550 feet. Credit: Amel Pain/EPA-EFE/ShutterstockThe Jeddah Tower, designed by Adrian Smith + Gordon Gill Architecture, is intended to stand at more than twice the height of Central Park Tower when complete, at 3,280 feet, PEOPLE previously reported. At that height, the Jeddah Tower will also surpass that of the Burj Khalifa in Dubai, which currently holds the record for the world's tallest building at 2,717 feet by a large margin.

AbstractChronic pain (CP) affects more than 30% of the global population and is often accompanied by significant cognitive impairments. Although an increasing number of studies have focused on the pathological mechanisms associated with chronic pain-induced cognitive impairments, most have concentrated on the stage after the onset of cognitive impairments. Currently, the course by which chronic pain induces cognitive impairment has not been fully reported. Therefore, single-cell RNA sequencing were conducted in this study in order to map the mice hippocampus altas before and after cognitive impairments induced by spared nerve injury (SNI) on days 3, 7, 14, and 21. After quality control screening, 53852 out of 64207 cells from 11 samples were retained for subsequent analysis. The reliability of the sequencing data was verified through analysis of various evaluation indicators and sequencing alignment rates.

Dianjunus rex can weigh more than 2 kilograms. [Photo/Kunming Institute of Botany under the Chinese Academy of Sciences]Chinese scientists have discovered a previously unknown giant fungus in Yunnan province that constitutes a new fungal family after finding specimens that can grow up to 50 centimeters tall and weigh more than 2 kilograms. Dianjunus rex was identified by a research team led by Yu Fuqiang of the Kunming Institute of Botany under the Chinese Academy of Sciences, together with collaborators. Their findings were recently published in the journal Frontiers in Fungal Biology. The research established an entirely new fungal family, Dianjunaceae, highlighting how much remains unknown about fungal diversity even in a region renowned for its rich plant and animal life, according to the team.

[Photo/Kunming Institute of Botany under the Chinese Academy of Sciences]Researchers collected specimens from tropical and subtropical forests in Yunnan between August 2024 and July 2025. The fungi were found growing from the roots of recently dead trees and surrounding soil.

Materials in a superconducting state are of huge interest to scientists. That's because of rare properties – primarily the ability to conduct electricity with zero resistance, with nothing lost to heat – that promise to transform computing, energy grids, and transport. This phenomenon happens when free electrons condense into a low-energy quantum state at very cold temperatures, pairing up into what are called Cooper pairs so they can zip through materials without interference. Back in 2007, scientists predicted the existence of a more exotic type of electron movement, called a pair density wave (PDW), where the Cooper pairs form specific patterns while moving, like ripples on sand. Now a team led by researchers from the University of Illinois at Urbana-Champaign has found compelling evidence of PDWs on the surface of the metal uranium ditelluride, with their results published in PNAS. What's more, the patterns were found to persist outside of the standard superconducting state, something that's never been seen before. "Pair density waves are the Cheshire Cat's grin of superconductivity," says physicist Eduardo Fradkin from the University of Illinois at Urbana-Champaign.
