A path to better MTV-MOFs

Scientists have developed a method to accurately predict the adsorptive properties of crystalline MTV-MOF systems, enabling the optimization of function and control of spatial disorder. The approach uses solid-state nuclear magnetic resonance (NMR) measurements with molecular-level computational simulations.

Trust thy neighbor

A study by Jordan Smith found that residents in growing communities trust information from family members, churches, and local newspapers more than elected officials or national news sources. This shift can lead to conflicts over values and ideologies, complicating long-term environmental and community planning.

Is sous vide cooking safe?

Scientists from Norwich BioScience Institute have gathered data to assess the hazards of lower temperature cooking in sous vide, filling a knowledge gap. They propose a way forward to ensure consistent and effective safety assessments, commensurate with any risk to public health.

Magnetic switching simplified

Researchers have discovered a new effect that enables easier production of spin-polarized currents necessary for magnetic chip switching. This breakthrough could lead to more efficient and robust magnetic Random Access Memories (MRAMs) for information processing.

Cute and armed at the same time

Researchers discovered a 165-million-year-old fossilized skeleton of the ancient mammal Megaconus mammaliaformis in Northeast China. The animal had striking cusps on its teeth for crushing hard plant material and powerful jaws for eating tough plants.

Novel beams made of twisted atoms

Physicists have built a theoretical construct of twisted atom beams, which can have potential applications in quantum communication and atomic processes. These beams were created by solving the non-relativistic Schrödinger equation for atoms driven by a laser field.

Micro-machines for the human body

Researchers at Tel Aviv University have created a novel printing process to produce micro-electromechanical systems (MEMS) components from a highly flexible and non-toxic organic polymer. This innovation enables the creation of biocompatible MEMS for medical devices, such as bionic arms and smart prosthetics.

Angry opponents seem bigger to tied up men

Research published in PLOS ONE found that physical handicaps like being tied down make men overestimate an opponent's size and underestimate their own. This effect persists even when anxiety is ruled out, suggesting an automatic processing of physical capacities towards potential conflicts with others.

Practice at 'guesstimating' can speed up math ability

Research at Duke University found that practice in estimating and comparing quantities can improve math abilities, particularly for symbolic math skills. The study tested adult volunteers before and after training sessions, showing significant improvement in math test scores compared to a control group.

Motional layers in the brain

Researchers at Max Planck Institute of Neurobiology discovered the cells responsible for processing motion in fruit flies, showing that motion information is processed independently in two separate pathways. The findings highlight the importance of understanding how neurons work together to enable complex behaviors.

Belief in precognition increases sense of control over life

Research suggests that believing in precognition can provide a psychological boost to perceived control, particularly when individuals feel a loss of control. People who experienced loss of control reported increased belief in precognition and subsequently felt more in control.

Electron 'spin' key to solar cell breakthrough

Organic solar cells have been found to improve their performance by manipulating the 'spin' of electrons, which can block energy collapse and increase current from the cell. This breakthrough could close the gap between organic and silicon solar cells, bringing large-scale deployment closer to reality.

Oregon burning

In July 2013, Oregon's severe drought and thunderstorms ignited dozens of difficult-to-control wildfires. The fires burned nearly 144,688 acres across the state, with smoke posing health risks to residents. Firefighters battled the blazes, including the Douglas Complex and Big Windy Complex, which collectively burned over 50,000 acres.
