长期以来被认为在地下安全封存数千年的古老碳正大量重返地表。一项大规模国际研究发现，河流释放的碳气体中超过半数来源于深层土壤和风化岩石等长期存在的古老碳源，而非近期形成的有机物。这一惊人发现表明，地球植被通过吸收过量碳来维持气候稳定的作用比预想的更为重要。

一项广泛的国际研究发现，河流释放的碳气体中有超过半数源自深层土壤和风化岩石等长期存在的古老碳源，而不仅限于近期有机物。这项惊人发现表明，地球植被通过吸收过剩碳来调节气候的作用远超预期——本应在地下安全封存数千年的远古碳正在实际重新浮出地表。

A protein that gives fleas their bounce has been used to boot out bacteria cells, with lab results demonstrating the material's potential for preventing medical implant infection.

Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), in collaboration with national and international research centers, have identified a key immune cell subtype involved in the development of atherosclerosis. In a stud

A joint research team has successfully developed a two-dimensional (2D) quantum material platform through the superposition of moiré lattices.

With recent advancements in technology, the Internet of Things and wireless devices are in high demand. However, these innovations also raise concerns about prolonged exposure to electromagnetic radiation (EMR), which may pose potential risks to eye healt

Limited penetration depth into tumor tissues continues to hinder the development of nanotherapeutics for cancer treatment. A novel self-propelled ferroptosis nanoinducer developed by Southern Medical University was able to achieve deeper penetration into

Chemistry often conjures images of mixing fluids together in beakers, flasks, or test tubes. But often, chemistry happens on a much smaller scale. In many medical and industrial contexts, mixing fluids involves fractions of a milliliter, and for these app

Whether it's electric vehicles, drones, or spacecraft, a common technical challenge for future transportation is lightweighting.
