“HUBERT AIRY first became aware of his affliction in the fall of 1854, when he noticed a small blind spot interfering with his ability to read. “At first it looked just like the spot which you see after having looked at the sun or some bright object,” he later wrote. But the blind spot was growing, its edges taking on a zigzag shape that reminded Airy of the bastions of a fortified medieval town. Only, they were gorgeously colored. And they were moving.
“All the interior of the fortification, so to speak, was boiling and rolling about in a most wonderful manner as if it was some thick liquid all alive,” Airy wrote. What happened next was less wonderful: a splitting headache, what we now call a migraine.”
Powerful advances in genome sequencing technology, informatics, automation, and artificial intelligence, have propelled humankind to the threshold of a new beginning in understanding, utilizing, and conserving biodiversity. For the first time in history, it is possible to efficiently sequence the genomes of all known species, and to use genomics to help discover the remaining 80 to 90 percent of species that are currently hidden from science.
(Phys.org)—A team of researchers with the University of Côte d’Azur in France has found that drops ejected by an oscillating surface can at times travel faster than the surface that ejected them. In their paper published in the journal Physical Review Letters, the team describes experiments they conducted by flinging water from a superhydrophobic surface and what they found.
We investigate the behavior of droplets and soft elastic objects propelled with a catapult. Experiments show that the ejection velocity depends on both the projectile deformation and the catapult acceleration dynamics. With a subtle matching given by a peculiar value of the projectile/catapult frequency ratio, a 250% kinetic energy gain is obtained as compared to the propulsion of a rigid projectile with the same engine. This superpropulsion has strong potentialities: actuation of droplets, sorting of objects according to their elastic properties, and energy saving for propulsion engines.

The detection of thousands of extrasolar planets by the transit method naturally raises the question of whether potential extrasolar observers could detect the transits of the Solar system planets. We present a comprehensive analysis of the regions in the sky from where transit events of the Solar system planets can be detected. We specify how many different Solar system planets can be observed from any given point in the sky, and find the maximum number to be three. We report the probabilities of a randomly positioned external observer to be able to observe single and multiple Solar system planet transits; specifically, we find a probability of 2.518 per cent to be able to observe at least one transiting planet, 0.229 per cent for at least two transiting planets, and 0.027 per cent for three transiting planets. We identify 68 known exoplanets that have a favourable geometric perspective to allow transit detections in the Solar system and we show how the ongoing K2 mission will extend this list. We use occurrence rates of exoplanets to estimate that there are 3.2 ± 1.2 and
temperate Earth-sized planets orbiting GK and M dwarf stars brighter than V = 13 and 16, respectively, that are located in the Earth’s transit zone.
The Ethiopian government is calling for the restitution of a sacred object that is sealed inside an altar in London’s Westminster Abbey. The object, known as a tabot, is a tablet that symbolically represents the Ark of the Covenant and the Ten Commandments. Every Ethiopian church houses a covered tabot, which is regarded as sacrosanct and must be seen only by the priest.
Westminster Abbey’s tabot was looted at the battle of Maqdala (formerly Magdala) in 1868, when British troops attacked the forces of the Ethiopian emperor Tewodros.
Last month(2018), following publicity surrounding the opening of the abbey’s museum, the Ethiopian ambassador in London reiterated his government’s claim. Hailemichael Aberra Afework told The Art Newspaper: “We are urging all those who hold items looted from Ethiopia to return them. This includes the tabot held at Westminster Abbey.” It would be inappropriate for a tabot to be displayed in a museum, so he believes that it should be returned to a church, with the Ethiopian synod permitted to decide which one.

In January 2017, Śri Vāsudevānada Saraswati, speaking about the spiritual significance of mother, referred to Mother Madālasā singing to her children, telling them that they are śudda, buddha and mukta, pure, conscious and free.
The song is part of the Madālasā Upadesa, or teachings of Madālasā. There are 8 verses of beautiful Sanskrit.
Gabriella Burnel was commissioned to set to music and perform the verses of the Song. The commission was funded by friends and students of the School of Practical Philosophy in Australia. The film is a video-recording of the final audio session in the London studios, generously provided by Gabriella.
