Phys.org / 100 million years ago, an 'evolutionary fuse' was lit in the deep ocean, sparking squid diversification
From color-changing skin to jet-propelled motion, squid and cuttlefish have long fascinated scientists. To understand the origins of their unique characteristics, many attempts have been made to define their evolutionary ...
Phys.org / Precision work prior to cell division: How enzymes optimize DNA structure
Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the DNA is wrapped around ...
Phys.org / Targeting the tiniest divide: Research reveals potential vulnerability in bacterial reproduction
A Université de Montréal study has found a previously unknown mechanism in bacterial reproduction that could be attacked by future antibiotics. Bacteria reproduce by dividing into two: they form a wall, or septum, between ...
Phys.org / Light switch for life: Controlling molecular droplets with UV
Biomolecular condensates are tiny, droplet-like structures made up of molecules that help organize key processes in living organisms. Because they are so small and constantly changing, it has been difficult for scientists ...
Medical Xpress / AI model can detect multiple cognitive brain diseases from a single blood sample
The symptom profiles of different neurodegenerative diseases often overlap, and diagnosing age-related cognitive symptoms is complex. A patient may have multiple overlapping disease processes in the brain at the same time, ...
Medical Xpress / Innovative targeted therapy halts prostate cancer spread to the bone
New findings from VCU Massey Comprehensive Cancer Center and the VCU Institute of Molecular Medicine (VIMM), published in Pharmacological Research, show that an innovative drug effectively prevents prostate tumors from spreading ...
Phys.org / One of cholera's great enemies is found in the human gut
Cholera-causing bacteria are locked in an evolutionary arms race with a viral nemesis, according to a new genomic study. Researchers have found that, in the Ganges Delta, cholera bacteria rapidly gain and lose special armor ...
Phys.org / Study examines diversity of Black perspectives on race relations
A new Rice University study offers one of the first national measures of a viewpoint called "racial realism" and considers how it fits into the broader spectrum of perspectives Black Americans hold about race relations.
Phys.org / Viruses 'eavesdrop' on each other—but it can backfire
University of Exeter scientists studied chemical communication by phages (viruses that infect bacteria). The phages assessed in the study have two choices when they enter a cell: lie dormant or kill the cell and release new ...
Phys.org / College students struggle to identify problematic gray zones in academic practice, study finds
Students across education levels have a blind spot for identifying situations that might bring their academic integrity into questionable territory, a study finds. When navigating questions on citation, collaboration, and ...
Phys.org / Phylogenetically diverse Central China proposed as newest global biodiversity hotspot
Taxonomic endemism and phylogenetic endemism are both important measures of biodiversity. The former describes the number of distinct species found nowhere else, whereas the latter shows the amount of evolutionary branch ...
Medical Xpress / Newly identified chronic pain circuit offers pathways to new treatments
A new map of a brain circuit specific to chronic pain suggests a promising route to treatment for the roughly 60 million Americans living with persistent pain, according to a study published in Nature. The study showed that ...
