Researchers present spontaneous sparse learning for PCM-based memristor neural networks

A team of researchers from UNIST developed a new learning method for PCM-based memristor neural networks, improving their learning ability by about 3% in handwriting classification tasks. The approach leverages the 'resistance drift' property of phase-change memory to update synapses and associate patterns with data.

When English and French mix in literature

A new study published in Language and Literacy explores the value of bilingual children's books in French immersion classrooms. Bilingual books are seen as an effective tool for second language learning, with students noting benefits such as learning French vocabulary and developing English knowledge. The study suggests that incorporat...

Skoltech and MIT researchers identify optimal human landing system architectures to land on the Moon

The study analyzed 39 variants of lunar human landers, considering key architectural decisions such as number of stages and propellant type. The analysis showed that expendable systems with 2-stage architecture are advantageous, but reusable vehicles with 1-stage or 3-stage systems offer comparable advantages.

Blight may increase public health risk from mosquito-borne diseases

Researchers found significantly higher Asian tiger mosquito populations and habitat availability in a low-income neighborhood with high levels of environmental blight. The study highlights the need for blight reduction efforts to mitigate public health risks from mosquito-borne diseases in vulnerable communities.

There might be many planets with water-rich atmospheres

Researchers at University of Chicago and Stanford University propose mechanism for formation and retention of water-dominated atmospheres on hot, rocky exoplanets. The model suggests these planets could have a water-rich atmosphere for long stretches, with some potentially keeping it for billions of years.

Double trouble for drug-resistant cancers

Researchers at Duke-NUS Medical School and A*STAR discovered that inhibiting the Wnt signalling pathway with ETC-159 can reverse PARP inhibitor resistance in several cancer cell lines. This breakthrough could lead to novel anti-cancer treatments for cancers with overactive Wnt signalling, such as colorectal cancer.
