Searching for Dyson spheres with Gaia

Assuming that Dyson spheres obscure optical/near-infrared light as grey absorbers, a partial Dyson sphere with high covering fraction (fcov > 0.5) could reveal itself as an anomalously subluminous star with a parallax-based distance smaller than... continue reading

The simple observation by Huygens that disproved Newton's rule for the extraordinary refraction of calcite

Huygens (1629–1695), in his Treatise on Light (1690), explained the double refraction of calcite on the correct hypothesis that the secondary waves for the... continue reading

A nanobattery based on biopolymers

Conventional batteries have been manufactured by top-down approach. It is believed that bottom-up approach offers better efficiency.... continue reading

Soap bar skin scanner for detection of early melanoma

Many scanners look inside the body, but none examine our whole skin because the ripples and folds of flesh need to be unfolded for camera access. The current approach assumes no cooperation from the person being examined, except to lie or stand... continue reading

Carbon concentrations in phytoliths and carbon sequestration in soil

In recent years there has been much work on the possibility that carbon could be sequestered in phytoliths and contribute to solving global warming.1,... continue reading

What do humans strive for, generally? A universal description of humans’ motivation to act.

When one considers a general and universal description of humans’ motivation to act, probably reproduction, or biological fitness, comes to mind (Darwin, 1859). However, there is an abundance of residual behaviour, across humans’ life domains... continue reading

Searching for "Tabby's Star" Analogs in Stripe 82

"Tabby's Star" is an anomalous F star with repeated short-term variability, and a steady 3% dimming over 4-years. The star spent... continue reading

Linking authorship and reviewing activity in science publishing

Everybody wants to publish, but peers for review are increasingly hard to find. Online systems that help journal editors handle submissions indicate how many invitations for review a person accepted or declined. Linking this information... continue reading

Algorithms learning for large scale facilities

A large scale facility can be described as an object producing, as an output, datasets D_i, that scientists analyse to obtain results R_i. The ideal data analysis trajectory for an experiment is thus D_i-->R-i-->P_i, where P_i denotes the... continue reading

The NASA K2 Mission has yet to observe an analog of Tabby's Star

Tabby's Star is a main sequence F-class star (KIC 8462852) observed by the NASA Kepler spacecraft to undergo significant aperiodic dimming activity across a four year baseline. The light curve was noted... continue reading
