While scientists are still determining exactly when and how these microbes appeared, it's clear that the emergence of life is intricately intertwined with the chemical and physical characteristics of early Earth.
Researchers use water treatment method to capture acids from agricultural waste
Bound for the landfill, agricultural waste contains carbon sources that can be used to produce high-value compounds, such as p-coumaric acid, which is used in manufacturing pharmaceuticals. Electrodeionization, a separation method that uses ion-exchange membranes, is one way to capture the acids and other useful components. However, to capture large quantities at scale, improvements to the method

Testing, explaining, and exploring models of facial expressions of emotions | Science Advances
Abstract Models are the hallmark of mature scientific inquiry. In psychology, this maturity has been reached in a pervasive question—what models best represent facial expressions of emotion? Several hypotheses propose different combinations of facial movements [action units (AUs)] as best representing the six basic emotions and four conversational signals across cultures. We developed a new frame
An electrically driven single-atom “flip-flop” qubit | Science Advances
Abstract The spins of atoms and atom-like systems are among the most coherent objects in which to store quantum information. However, the need to address them using oscillating magnetic fields hinders their integration with quantum electronic devices. Here, we circumvent this hurdle by operating a single-atom “flip-flop” qubit in silicon, where quantum information is encoded in the electron-nucle
The role of continental subduction in mantle metasomatism and carbon recycling revealed by melt inclusions in UHP eclogites | Science Advances
Abstract Subduction is the main process that recycles surface material into the mantle. Fluids and melts derived by dehydration and partial melting reactions of subducted continental crust, a major reservoir of volatiles (i.e., H 2 O and CO 2 ) and incompatible elements, can substantially metasomatize and refertilize the mantle. Here, we investigate glassy inclusions of silicate melt of continent
Hydrothermal-derived black carbon as a source of recalcitrant dissolved organic carbon in the ocean | Science Advances
Abstract Deep-sea hydrothermal vents are a possible source of thermogenic dissolved black carbon (DBC), which is a component of recalcitrant dissolved organic carbon, but little is known about the distribution of hydrothermal DBC in the deep ocean. Here, we show basin-scale distributions of DBC along two transects in the eastern Pacific Ocean, which are located outside the jet-like hydrothermal p
The Integrator complex regulates microRNA abundance through RISC loading | Science Advances
Abstract MicroRNA (miRNA) homeostasis is crucial for the posttranscriptional regulation of their target genes during development and in disease states. miRNAs are derived from primary transcripts and are processed from a hairpin precursor intermediary to a mature 22-nucleotide duplex RNA. Loading of the duplex into the Argonaute (AGO) protein family is pivotal to miRNA abundance and its posttrans
Turing pattern–based design and fabrication of inflatable shape-morphing structures | Science Advances
Abstract Turing patterns are self-organizing stripes or spots widely found in biological systems and nature. Although inspiring, their applications are limited. Inflatable shape-morphing structures have attracted substantial research attention. Traditional inflatable structures use isotropic materials with geometrical features to achieve shape morphing. Recently, gradient-based optimization metho
Collagen hydrogel viscoelasticity regulates MSC chondrogenesis in a ROCK-dependent manner | Science Advances
Abstract Mesenchymal stem cell (MSC) chondrogenesis in three-dimensional (3D) culture involves dynamic changes in cytoskeleton architecture during mesenchymal condensation before morphogenesis. However, the mechanism linking dynamic mechanical properties of matrix to cytoskeletal changes during chondrogenesis remains unclear. Here, we investigated how viscoelasticity, a time-dependent mechanical
One-dimensional alignment of defects in a flexible metal-organic framework | Science Advances
Abstract Crystalline materials are often considered to have rigid periodic lattices, while soft materials are associated with flexibility and nonperiodicity. The continuous evolution of metal-organic frameworks (MOFs) has erased the boundaries between these two distinct conceptions. Flexibility, disorder, and defects have been found to be abundant in MOF materials with imperfect crystallinity, an
Na, K-ATPase α1 cooperates with its endogenous ligand to reprogram immune microenvironment of lung carcinoma and promotes immune escape | Science Advances

Here, endogenous ouabain (EO), an adrenergic hormone, is elevated in patients with NSCLC and closely related to tumor pathological stage, metastasis, and survival. EO promotes the suppre
Subnanometer structure of an enveloped virus fusion complex on viral surface reveals new entry mechanisms | Science Advances

We use cryo–electron tomography to visualize the fusion complex of human parainfluenza virus 3 (HN/F) on the surface of authentic clinical viruses at
A highly specific CRISPR-Cas12j nuclease enables allele-specific genome editing | Science Advances
Abstract The CRISPR-Cas system can treat autosomal dominant diseases by nonhomologous end joining (NHEJ) gene disruption of mutant alleles. However, many single-nucleotide mutations cannot be discriminated from wild-type alleles by current CRISPR-Cas systems. Here, we functionally screened six Cas12j nucleases and determined Cas12j-8 as an ideal genome editor with a hypercompact size. Cas12j-8 di

The patch’s outer layer is composed of polyethylene glycol polyester hydrogel. The hydrogel forms hyd

The Speed of Gravity

This blew their mind, writing: “That statement doesn’t

Worse, it suggests that the two powers are close to a point where f
Fossil discovery reveals complex ecosystems existed on Earth much earlier than previously thought
About 250 million years ago, the Permian-Triassic mass extinction killed over 80 per cent of the planet's species. In the aftermath, scientists believe that life on earth was dominated by simple species for up to 10 million years before more complex ecosystems could evolve. Now this longstanding theory is being challenged by a team of international researchers.
