Are we wiser about tsunamis? Expert says yes and no

A Northwestern University expert found mixed results on human preparedness for tsunamis, with significant progress made in tsunami science and education. However, substantial challenges remain, including the impact of 'tsunami earthquakes' and the need to incorporate new knowledge into warning procedures.

CSI -- on the metabolite's trail

A team of bioinformaticians at the University of Jena has developed a new search engine, 'CSI:FingerID', that significantly simplifies the identification of molecular structures of metabolites. The tool reduces the number of possible compounds from thousands to ten, making it feasible for precise lab tests to identify specific compounds.

New graphene oxide biosensors may accelerate research of HIV and cancer drugs

Researchers have developed a novel type of graphene oxide-based biosensor that can detect biomolecules at a few trillionth of a gram per millimeter square. The sensor's sensitivity is three times higher than commercially available chips, making it ideal for analyzing chemical reactions with small drug molecules.

Chemistry for the methanol economy

A Franco-Swiss research team has proposed a new explanation for the starting mechanism of the MTO process. They found that alumina, present in zeolites, can transform methanol into ethylene and other hydrocarbons, which can then be converted into carbenium ions. This discovery sheds light on how the MTO process begins.

Dirty, crusty meals fit for (long-dormant) microbes

Researchers used exometabolomics to study the interactions between soil microbes and their adaptations in desert biocrusts. The team found that diverse microbes target specific metabolites, supporting diverse microbial communities. This discovery suggests a possible mechanism for promoting soil biodiversity by specialization.

A fast cell sorter shrinks to cell phone size

A team of researchers developed a cell sorter based on acoustic waves that can compete with existing fluorescence-activated cell sorters, sorting up to 13,000 cells per second while gently manipulating individual cells. The device is compact, inexpensive, and preserves cell viability and functions.

Research uncovers microsopic key to reducing ocean dead zones

Scientists at Brigham Young University have made a breakthrough in reducing ocean dead zones by studying the potential of rhizobia, a type of beneficial bacteria. By understanding how these bacteria interact with plants, researchers aim to develop more sustainable farming practices that minimize fertilizer use and reduce water pollution.

Benign by design

The UCSB organic chemistry team, led by Bruce Lipshutz, developed an ecofriendly approach to the Suzuki-Miyaura cross-coupling reaction, significantly reducing palladium requirements. By using iron salt as a palladium substitute, they eliminated heat input and organic solvents, creating a more sustainable process.

Better trap for greenhouse gases

Researchers have discovered that vertically aligned carbon nanotubes (VACNTs) can be used to capture and store greenhouse gases like carbon dioxide and sulfur dioxide more effectively than traditional adsorption materials. The study found that adjusting the morphological parameters of VACNTs can significantly impact gas adsorption.

Unexpected link between choroid plexus and chronic pain

Researchers found a novel connection between the size of the choroid plexus and complex regional pain syndrome (CRPS), with nearly one-fifth larger choroid plexus in CRPS patients compared to healthy control subjects. The study suggests that the central nervous system plays an important role in the disease.
