A speck of dust measures halfway between the size of an atom and Earth.

For the past decade MIT's Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) has supported interdisciplinary collaborations and high-risk, high-reward projects, enabling MIT faculty to pursue groundbreaking research that addresses some of the world's most pressing challenges facing our water and food systems.

Reverse transcription has frequently been co-opted for cellular functions and in prokaryotes is associated with protection against viral infection, but the underlying mechanisms of defense are generally unknown. Here, we show that in the DRT2 defense ...

Good options exist in the frontline setting, but relapsed/refractory cases remain a challenge.

Structure-guided design of SARS-CoV-2 PLpro inhibitors yields an antiviral molecule with in vivo efficacy in a mouse model.

Alkenes represent one of the most abundant classes of organic molecules, which are available in bulk quantities from petroleum and renewable resources, with various utilization in agrochemistry, pharmacy, and organic materials. Typically, the transformation of alkenes by cleavage of both the σ bond and π bond underpins a range of industrial processes and provides methods for the reconstruction of hydrocarbon…

Hydrogels inevitably undergo dehydration, structural collapse, and shrinkage deformation due to the uninterrupted evaporation in the atmosphere, thereby losing their flexibility, slipperyness, and manufacturing precision.

Response rates with pirtobrutinib reached 72% in heavily pretreated patient population

The protons and neutrons in a nucleus can form clusters analogous to atoms in a molecule, even in the nuclear ground state.

Carbon nanotube (CNT) hybrid composites were formed by combining a CNT and silicone elastomer solution with Kevlar yarn, Kevlar fabric, and Kevlar veil materials. The integration of a CNT-silicone matrix with Kevlar yarn and fabric materials produced a composite with moderate electrical and thermal conductivity due to CNT fabric combined with the strength of Kevlar fabric or yarn. In the material synthesis, a…

Near-infrared (NIR)-emitting phosphor-converted light-emitting diodes (pc-LEDs) have attracted attention in emerging technology fields such as night-vision and bio-imaging. Currently, the development of NIR-emitting pc-LEDs has encountered a bottleneck due to the lack of blue-light excitable high-performance NIR-emitting phosphor materials.

Space policy is already a site of class struggle, and the mining and militarization haven't even begun. It's left-wing space policy or barbarism.

Nearly 40 years of research into the contaminated area around Chernobyl is providing some clues.

A facile technique for reproducibly creating Swiss-cheese-like nanomaterials has been developed by researchers at KAUST. This material, and the method required to create it, could help in the development of further advanced materials with applications in photocatalysis and optoelectronics.

A research group led by Professor Hideki Fujiwara and Associate Professor Daisuke Sakamaki from the Graduate School of Science at Osaka Metropolitan University succeeded, for the first time, in synthesizing a new molecule using a novel combination of dynamic covalent chemistry, in which organic radicals couple and dissociate reversibly, and coordination chemistry, which binds radicals to metal ligands. The study…

Northwestern Medicine investigators have developed a novel nanoparticle treatment for glioblastoma, according to a study published in Nature Communications.

Prof. Liang Haojun from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a new catalytic assembly approach to escape from metastable states in a far-from-equilibrium system of DNA-functionalized colloids. The study was published in the Proceedings of the National Academy of Sciences.

Physicists and material scientists have been trying to metallize hydrogen for many decades, but they have not yet succeeded. In 1968, British physicist Neil Ashcroft predicted that atomic metallic hydrogen would be a high-temperature semiconductor.

Over two and a half billion years ago, a simple photosynthesizing bacterium emerged on planet Earth. Having stumbled upon a way to convert sunlight and CO2 into energy, it began releasing oxygen into the atmosphere. So much oxygen that anaerobic life was utterly destroyed. This mass extinction is known as the Great Oxygenation Event. It is also called the Oxygen Holocaust. It is quite possibly the most destructive…
