Sleep helps process emotions
Researchers at the Department of Neurology of the University of Bern and University Hospital Bern identified how the brain triages emotions during dream sleep to consolidate the storage of positive emotions while dampening the consolidation of negative ones. The work expands the importance of sleep in mental health…

Differences between expert and novice brains in mice: study
When mice learn to do a new task, their brain activities change over time as they advance from ‘novice’ to ‘expert.’ The changes are reflected in the wiring of cell circuits and activities of neurons. Using a two-photon imaging microscope and a wealth of genetic tools, researchers from Cold Spring Harbor Laboratory…

Protons are probably smaller than long thought
Our office chair, the air we breathe, the stars in the night sky: they are all made of atoms, which in turn are composed of electrons, protons and neutrons. Electrons are negatively charged; according to current knowledge, they have no expansion, but are point-like. The positively charged protons are different …

Research shows plant-based polymers can disappear within seven months
Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research from scientists at UC San Diego and Algenesis shows that their plant-based polymers biodegrade — even at the microplastic level — in under seven months.

Philippine ethnic group has most Denisovan DNA
The Philippine ethnic group Ayta Magbukon has the highest proportion of genes from our extinct relatives, the Denisovans, a new study led by Uppsala University shows. Their Denisovan share far exceeds that of ethnic groups in Papua New Guinea, who previously held the record. The study is published in the scientific…
