Proteins
Research from McMaster University in Hamilton, Canada, has shed new light on the bacterial world, revealing a family of proteins that exhibit broad-spectrum antibacterial activity against a diverse range of target organisms. Known as diffusible antibacterial proteins (ABPs), these enzymes degrade essential cellular components, including DNA, tRNA, and rRNA, ultimately
Anisotropy
Researchers at the National Academy of Sciences of Ukraine have made a significant discovery regarding the influence of flexoelectric coupling on the fluctuations of electric polarization and elastic strains in van der Waals ferrielectrics. According to their study, the dispersion law of soft optical and acoustic phonons (flexophonons) and ferrons
Proteins
Researchers from Discovery Sciences have made a groundbreaking discovery in the field of cryogenic electron microscopy (cryoEM), demonstrating that it is possible to thin and vitrify a specimen for cryoEM faster than proteins diffuse to the air-water interface. This achievement was made possible by spraying picoliter volume droplets at speeds

Researchers from Pomona College have developed a brain-based framework that can predict hidden psychological states, such as feeling overwhelmed, burned out, or disengaged, in workplace settings. The framework uses noninvasive neuroimaging to identify key neural activity patterns associated with these states. The study found that functional near-infrared spectroscopy (fNIRS) recordings

Mental health
Recent research at the University of Southern California's Keck School of Medicine has revealed the profound impact of early life adversity (ELA) on brain function, increasing the risk of physical and mental disorders into adulthood. The study, which has been peer-reviewed, employed longitudinal manganese-enhanced MRI (MEMRI) to track

Research has shed new light on the functional role of spontaneous activity in astrocytes, a type of glial cell in the brain, in the process of memory consolidation. According to findings published in the Proceedings of the National Academy of Sciences, spontaneous activity in astrocytes, which was previously thought to
Journalistic ethics
Researchers at Beihang University in China have made a groundbreaking discovery in the field of quantum sensing, developing a new atomic comagnetometer that is capable of probing beyond-Standard-Model interactions with unprecedented sensitivity. By operating under a resonantly-coupled hybrid spin-resonance (HSR) regime, the comagnetometer is able to achieve robust nuclear-electron spin

Research conducted at Princeton University suggests that vocal development in human infants is strongly influenced by interactions with caregivers who reinforce more speech-like sounds. This trajectory of vocal development in humans is distinct from that of their close phylogenetic relatives, cercopithecoid monkeys and apes. The study found that the evolution

Researchers at Yale University have made a significant discovery about the immune responses of neonates, revealing that early-life human CD8+ T cells exhibit rapid, short-lived effector responses and a unique transcription factor landscape. This research has the potential to provide new insights into the development of effective treatments for viral
Genes
Researchers at the National Academy of Sciences of Ukraine have made a significant discovery in the field of genomics, shedding light on the evolution of tubulin gene family in Camelina species. The study, published in Cytology and Genetics, employed a range of bioinformatics approaches to identify and characterize tubulin genes
Extrasolar planets
Current research aims to detect Earth-like terrestrial planets in the habitable zone around Sun-like stars, but such planets are currently at the detection limit. The Kepler space telescope has identified 47 candidates, but their statistical significance has not been accurately estimated. A new study proposes a method to modify the
