A rapidly spreading virus threatens the health of the cacao tree and the dried seeds from which chocolate is made, jeopardizing the global supply of the world’s most popular treat. Researchers have developed a new strategy: using mathematical data to determine how far apart farmers can plant vaccinated trees to prevent mealybugs from jumping from one tree to another and spreading the virus.

A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks — side-channel attacks and bus-probing attacks.

A study suggests timely reporting and investigating of livestock abortions is feasible in rural areas and can provide insights into emerging infectious diseases.

Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once sealed away by ice as the likely causes.

Psychologists have found that people are as hesitant to reach out to an old friend as they are to strike up a conversation with a stranger, even when they had the capacity and desire to do so.

A team of researchers found that long-tie connections accelerate the speed of social contagion.

Researchers describe the steps they took to manipulate DNA and proteins — essential building blocks of life — to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.
