Starship SN6 prepares for hop â Super Heavy is coming
Posted by Genevieve Klien in categories: Elon Musk, space travel
Starship SN6 is aiming to conduct a 150-meter hop test on Sunday, just a few weeks after SN5 completed the first Starship prototype launch. SN6âs test will be a near-mirror of SN5âs short flight, with both prototypes aiming to refine SpaceXâs launch and landing operations. Meanwhile, additional Starships continue to evolve, along with preparations for the Super Heavy booster, which â according to Chief Designer Elon Musk â could conduct an initial test hop by October.
SN5 and SN6:

âJumpingâ DNA Regulates Human Neurons
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
Summary: Transposable elements team up with evolutionary recent neurons to influence differentiation and physiological function of neurons in brain development.
Source: EPFL
The human genome contains over 4.5 million sequences of DNA called âtransposable elementsâ, these virus-like entities that âjumpâ around and help regulate gene expression. They do this by binding transcription factors, which are proteins that regulate the rate of transcription of DNA to RNA, influencing gene expression in a broad range of biological events.

First Physics-Based Method for Predicting Large Solar Flares
Posted by Genevieve Klien in categories: particle physics, space
Solar flares emit sudden, strong bursts of electromagnetic radiation from the Sunâs surface and its atmosphere, and eject plasma and energetic particles into inter-planetary space. Since large solar flares can cause severe space weather disturbances affecting Earth, to mitigate their impact their occurrence needs to be predicted. However, as the onset mechanism of solar flares is unclear, most flare prediction methods so far have relied on empirical methods.
The research team led by Professor Kanya Kusano (Director of the Institute for Space-Earth Environmental Research, Nagoya University) recently succeeded in developing the first physics-based model that can accurately predict imminent large solar flares. The work was published in the journal Science on July 31, 2020.
The new method of flare prediction, called the kappa scheme, is based on the theory of âdouble-arc instability,â that is a magnetohydrodynamic (MHD) instability triggered by magnetic reconnection. The researchers assumed that a small-scale reconnection of magnetic field lines can form a double-arc (m-shape) magnetic field and trigger the onset of a solar flare (Figure 1). The kappa scheme can predict how a small magnetic reconnection triggers a large flare and how a large solar flare can occur.
