Auxin makes the spirals in gerbera inflorescences follow the Fibonacci sequence

Researchers have found that the spirals in gerbera inflorescences follow the Fibonacci sequence, with the number of left- and right-winding spirals determined by consecutive Fibonacci numbers. The study used X-ray tomography and confocal microscopy to examine how auxin levels influence the patterning of floral primordia.

Study sheds more light on use of oxytocin during labour

A recent study published in The BMJ found that discontinuing oxytocin stimulation during induced labour may lead to a reduced risk of uterine hyperstimulation and abnormal fetal heart rate. This finding suggests that routine discontinuation of oxytocin stimulation could be beneficial in settings with limited monitoring resources.

Interlayer exciton formation, relaxation, and transport in TMDs van der Waals Heterostructures

Research on interlayer excitons in TMDs vdW heterostructures reveals ultrafast formation, long population recombination lifetimes, and intriguing spin-valley dynamics. The properties ensure good transport characteristics and pave the way for potential applications in efficient excitonic devices.

Lab study solves textbook problem: How cells know their size

A recent study from Dartmouth College has uncovered the mechanism behind how cells determine their size, a crucial process that regulates cell division in growing organisms. The research found that histone H3 plays a key role in this process, releasing an enzyme called Chk1 to bind with another protein and stop cell multiplication.

New study reveals charge transfer at interface of spinel oxide and ceria during CO oxidation

A recent study has unveiled a new principle that active charge transfer at the interface between non-noble metals can enhance the catalytic performance of complex oxide catalysts. The researchers found that CeO2-deposited spinel oxide nanocubes exhibited a 12-times higher CO oxidation rate than pristine Co3O4 NCs.

Cultivating Matsutake, valuable edible fungi

Researchers at Shinshu University successfully cultivated matsutake mushrooms by germinating spores and inducing mycelia in the soil of Japanese red pine roots. This breakthrough could lead to an artificial cultivation technique for these valuable edible fungi, addressing declining natural habitats.

Using sound waves to make patterns that never repeat

Mathematicians and engineers at the University of Utah have developed a method to create quasiperiodic structures using ultrasound waves, which could lead to customizable materials. The researchers created a pattern similar to a Penrose tiling by arranging carbon nanoparticles in an octagonal setup.

New study reveals brain basis of psychopathy

A Finnish study found that psychopathic criminal offenders and well-functioning individuals with similar traits have altered brain structure and function in emotional regulation areas. The more psychopathic characteristics a person has, the more their brain resembles that of psychopathic criminals.

Most differences in DNA binding compounds found at birth in children conceived by IVF not seen in early childhood, NIH study finds

A NIH study found that newborns conceived through IVF had certain chemical modifications to their DNA, but these changes were not seen in early childhood. The study also found no differences in growth and development for this group.

HSE University researchers track language abilities of russian children with ASD

A study published in Journal of Autism and Developmental Disorders describes the language abilities of Russian children with Autism Spectrum Disorder (ASD) at various linguistic levels. The researchers found significant differences between groups in all subtests, except for the simplest word repetition. Children with ASD had lower accu...
