Ateam of researchers led by Harvard and Broad Institute scientists has developed twin prime editing, a new, CRISPR-based gene-editing strategy that enables manipulation of gene-sized chunks of DNA in ...
Differences in genetic and environmental variation in adult BMI by sex, age, time period, and region: an individual-based pooled analysis of 40 twin cohorts
BMI adults genetics twins international comparisons
2018/11/15
Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood.
Genetic and environmental effects on body mass index from infancy to the onset of adulthood: an individual-based pooled analysis of 45 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) study

Background: Both genetic and environmental factors are known to affect body mass index (BMI), but detailed understanding of how their effects differ during childhood and adolescence is lacking.

Mismatched Twin Stars in the Delivery Room
2015/3/4
The majority of stars in our galaxy come in pairs. In particular, the most massive stars usually have a companion. These fraternal twins tend to be somewhat equal partners when it comes to mass - but ...
Focal mechanism and depth of the 1956 Amorgos twin earthquakes from waveform matching of analogue seismograms
Simulation seismograms Amorgos twins earthquake volcanic arc subduction zone focal mechanism
2015/1/6
Historic analogue seismograms of the large 1956 Amorgos twin earthquakes which occurred in the volcanic arc of the Hellenic subduction zone (HSZ) were collected, digitized and reanalyzed to obtain ref...
Proof of hypothesis of twin primes (important step: choosing a suitable interval)

1. Distributive law of primes: (x/㏒x)㏒e＜π(x)≤(x/㏒x) ㏒11330／113, (11≤x＜∞); 2. Shortest suitable interval, [11, 19]; 3. Expression of twin odd numbers, ︱2x－11,…,…,…,4x－27︱ ︱2x－ 9,…,…,…,4x－25︱, Number of...
Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae--colorful, glowing clouds of dust and gas. In recent decades,...
The proofs of twin prime conjecture and weaker Polignac's conjecture

2011/9/6
Abstract: The results of the computer investigation of the sign changes of the difference between the number of twin primes $\pi_2(x)$ and the Hardy--Littlewood conjecture $C_2\Li_2(x)$ are reported. ...

2011/9/28
The Tornado nebula (G357.7-0.1) is a mysterious radio source with bright "head" and faint "tail" located in the direction of the Galactic center (GC) region. We here report the discovery of two diffus...
