Three magnetic states for each hole

Researchers at Helmholtz-Zentrum Dresden-Rossendorf have developed cobalt grids that can be reliably programmed at room temperature. Three distinct magnetic states, denoted as G, C, and Q, were found around each hole in the grid. This discovery could lead to more efficient computing using spin-waves instead of electric current.

Research pushes concept of entropy out of kilter

New research at Brown University finds that a non-equilibrium phenomenon relies on entropy to emerge, surprising scientists who thought disorder would decrease as systems move away from equilibrium. The study's results have implications for our understanding of entropy and may lead to new practical applications.

Online scrutiny is stressful for doctors

A study found that online ratings and comments significantly increase doctor job stress, with 78% of physicians feeling the impact. Patients also use online reviews to make informed choices, but may be hesitant to share their own experiences due to concerns about bias.

Model assesses interventions for bovine tuberculosis in Morocco

A mathematical model of bovine tuberculosis transmission from cattle to cattle and cattle to humans was used to analyze the cost and effectiveness of interventions in Morocco. The results showed that using a more conservative cutoff for a positive skin test could lead to cheaper and quicker elimination of the disease.

Research review shows that safety is valued too low

A new research review suggests that the UK's nuclear safety benchmark undervalues human life, with a current figure of £1.83 million per prevented fatality potentially too low. A revised estimate, considering a more robust methodology, places the value at between £16 million and £22 million per life saved.

New scoring system predicts Ebola severity

Researchers developed a new scale to predict patient outcomes, finding that malaria co-infection, age extremes, and delayed healthcare seeking behavior are key predictors of mortality. The scoring system achieved high accuracy rates of 91% at triage and 97% after triage.

NYU's Panozzo wins NSF CAREER award

Professor Panozzo will work on developing algorithms that combine 3D scanning and digital fabrication technologies, enabling new applications in life sciences and medicine. The $554,000 grant aims to enhance the design of customized medical devices and improve cell tracking techniques.

Why am I shorter than you?

A recent study has identified 83 DNA variants that modulate human height, with some affecting it by more than 2 cm. The discovery is significant for understanding the genetic basis of complex diseases such as diabetes and schizophrenia, and may lead to the development of new therapeutic strategies.

Common pain relievers may increase heart attack risk during respiratory infections

A new study suggests that widely used pain relievers may increase the risk of a heart attack when used during a cold or flu-like illness. Researchers found a stronger association with a heart attack when both an acute respiratory infection and NSAID use were present, with a 3.4-fold increased risk for a heart attack.

Plan to reduce air pollution chokes in Mexico City

A study by UC Berkeley's Haas School of Business found that Mexico City's Saturday driving restrictions have negligible impact on air quality. The program, which restricts vehicles with license plates ending in '5' or '6', did not lead to a decrease in pollution levels for any of the eight major pollutants monitored. Instead, experts r...

Easier to let go -- can depression help people deal with life?

Patients with depression are more successful than healthy individuals in abandoning unattainable goals. By giving up on unrealistic objectives, depression can actually facilitate personal development. Researchers found that individuals with depression spent less time on unsolvable anagrams, indicating a greater ability to disengage.
