Scientists develop “aging clocks” to measure body decline

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Aging is a complex process, and precisely measuring how the human body declines has long been a challenge. Two people of the same chronological age can have very different health trajectories. Scientists have also struggled to move beyond identifying aging markers to pinpointing what actually drives aging itself. Now researchers from China’s Aging Biomarker Consortium (ABC) have built a computational framework—the Digital Aging Twin—to study aging at the individual level in order to predict biological age and track the different aging rates of individual organs.

Research shows soil temperature modulated millet agriculture in Neolithic East Asia

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

To better understand how environmental conditions may have shaped the development of millet agriculture, researchers from the Institute of Earth Environment of the Chinese Academy of Sciences, and their collaborators in and aboard China investigated loess deposits from the Chinese Loess Plateau (CLP).

Chemical hardness engineering boosts perovskite tandem efficiency to 30.3%

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A research team led by Prof. GE Ziyi and Prof. LIU Chang at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has developed a chemical-hardness-guided strategy to control crystallization in all-perovskite tandem solar cells—achieving a certified power conversion efficiency of 30.3% in rigid devices and 28.0% in flexible tandems.

DAMPE observes charge-dependent limit of cosmic ray acceleration

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

The international collaboration of the DArk Matter Particle Explorer (DAMPE) satellite has, for the first time, directly observed the charge-dependent "spectral softening" of five primary cosmic-ray nuclei, i.e. protons, helium, carbon, oxygen, and iron, whereby the number of these particles drops off more steeply at higher energies.

LHAASO discovers new extreme particle accelerator in the Milky Way

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

The Large High Altitude Air Shower Observatory (LHAASO) has made a breakthrough in exploring the extreme universe. For the first time, the LHAASO collaboration has detected ultra-high-energy (UHE) gamma rays—with energies exceeding 100 trillion electron-volts (TeV)—from a gamma-ray binary system, LS I +61° 303.

Study reveals soil, not fertilizer, is primary source of nitrogen gas loss in rice paddies

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A new study led by Prof. YAN Xiaoyuan from the Institute of Soil Science of the Chinese Academy of Sciences has overturned the long-held assumption about nitrogen loss in agriculture. Published in PNAS on April 22 as a cover article, the study reveals that most nitrogen gas (N₂) emissions from rice paddies originate from soil organic nitrogen (SON), rather than applied fertilizers.

LHAASO discovers 'aquila booster,' challenging theoretical limits of particle acceleration in pulsar wind nebulae

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (10¹⁵ eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron and posing a challenge to the classical theory of particle acceleration in pulsar wind nebulae.
