Espresso-strength coffee was made with room-temperature water by using ultrasound to accelerate extraction. In blind tasting, most participants could not distinguish it from traditional espresso. doi.org/hb6874
Acidic nanoparticles restored lysosomal acidity in Parkinson’s models, helping restart the cell’s waste-clearing system. Toxic protein buildup fell, but delivery to the brain is still being refined. doi.org/hb6873
Ancient whole-genome duplications may have supplied the gene copies that helped vertebrate brains diversify their cell types. Across five species, retained duplicates were more often tied to distinct cell identities.
Argonaute appears to open into a chaperone-held state so a small RNA can load. That RNA then helps the protein fold into its active gene-silencing form, but only if key features are preserved.
The deep sea yielded more than 500 million unique genes, but many essential protein shapes remained strikingly similar. That contrast hints at rapid genetic change anchored by stable designs.
The first complex cells may have formed through multiple microbial alliances, not mitochondria alone. Genomic traces in the common ancestor of all eukaryotes point to added bacterial and viral signals.
In stressed mice, liraglutide’s antidepressant-like effect appeared to depend on the gut microbiome, not direct buildup in the brain. When gut microbes were depleted, the effect disappeared.
More icebergs have been moving through the Fram Strait since the early 2000s, often in larger groups. As they melt, stones drop onto the soft deep seafloor and create new hard habitat.
A deep-sea “whale necropolis” in the southeastern Indian Ocean preserves active whale falls and hundreds of fossil sites from 4,616 to 7,001 meters. The record stretches back at least 5.3 million years.
At-home memory tests on smartphones and tablets tracked subtle cognitive decline within months in people with mild cognitive impairment. Standard assessments are usually much less frequent. doi.org/hb686k

Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room-temperature water, cutting energy use by up to 75%.
Some people taking GLP-1 drugs for diabetes and obesity experience mental health benefits—particularly a decrease in symptoms of depression.

New findings, published in Nature, help answer the riddle of how vertebrates evolved the diverse array of brain cells that distinguishes them from other animals.
The deep sea is a unique "evolutionary engine," with one of the richest and most unexplored sources of genetic diversity on Earth, according to a major new study that assessed its potential to transform biotechnology and DNA sequencing technologies.
Inside every human cell, a tiny structure called a lysosome acts like a recycling center, breaking down toxic waste, clearing damaged proteins and helping keep the cell functioning properly.
RNA therapeutics have emerged as one of the most promising new classes of medicines. Eight small interfering RNA (siRNA) drugs have already been approved worldwide for the treatment of genetic diseases, yet scientists have not fully understood one of the most fundamental steps underlying their function: how Argonaute, the core protein responsible for gene silencing, becomes activated.

The number of icebergs in the Arctic has increased sharply since the 2000s. This is due to the destabilization of large glaciers in northeast Greenland and parts of the Russian Arctic, as well as the increasing mobility of sea ice.
All cells in animals, plants, fungi, and protists share a fundamental characteristic: they are eukaryotic cells—complex cells with specialized internal compartments.
People with mild cognitive impairment (MCI) are at higher risk of developing dementia. Indeed, many of them experience a gradual decline in cognitive performance over time.
