White Currants

From -Earth Unreal Edited by - Amal Udawatta, White currants belong to the Ribes genus, along with black currants and gooseberries. They are small, round berries that have a pale yellow or greenish-white color and a mild, sweet taste with some sourness. They are rich in vitamins C and K, as well as antioxidants. White currants are often used for baking, such as in pies and tarts, and can also be added to salads or used as a decoration for cocktails. They are also a common ingredient in European cuisine, especially in France and Germany. White currants grow best in cool climates and well-drained soil with partial shade, as they do not tolerate excessive heat or sun. They are usually planted in the fall or early spring and need regular pruning to keep their shape and fruit production. White currants are different from red currants only in the color and flavor of their fruits, which are translucent white and sweeter. Text credit: Earth Unreal Image credit: Dmitry Latyshev

Royal Society: Four incredible objects that made science history

  By Georgina Rannard BBC Climate and Science Reporter, Edited by - Amal Udawatta, IMAGE SOURCE, ROYAL SOCIETY Image caption, Fossil hunters on the south coast of England sent pictures of their finds to scientists One of the first scientific findings signed by a woman is now online for the public to see for the first time. Martha Gerrish's descriptions of the stars in 1734 joins discoveries by Isaac Newton, Victorian fossil hunters and pioneer photographers. The documents have been digitised by the scientific institution the Royal Society in London. It hopes it will lead to more discoveries as researchers use the archive. Around 250,000 documents can now be viewed online, covering everything from climate observations, the history of colour, how to conduct electricity, and animals. You can access the online archive  here.  We have picked out some of the highlights: First letter signed by a woman In 1734 a woman living in New England called Martha Gerrish wrote to the Royal Society t

Woolly aphids are insects that feed on the sap of plants

  Frrom - Wikipdia  Edited by Amal Udawatta, Woolly aphids     are  sap -sucking  insects  that produce a filamentous waxy white covering which resembles cotton or wool. The adults are winged and move to new locations where they lay egg masses. The nymphs often form large cottony masses on twigs, for protection from predators. Woolly aphids occur throughout the  Northern Hemisphere . Many of the numerous species of woolly aphids have only one  host  plant species, or alternating generations on two specific hosts. They have been known to cause botanical damage and are often considered a pest. While most damage is minor, they can spread plant diseases and fungi. Some species can produce galls as well. In flight they have been described as looking like "flying mice." Other nicknames include "angel flies", “cotton fairies”, "fluff bugs", "fairy flies", "ash bugs", "snow bugs", "fluffer fairies", "poodle flies&qu

Fiber optics take the pulse of the planet

          From - Kanowble Magazine           By - Carolyn Wilke,          Edited by - Amal Udawatta,                     Researchers Sara Klaasen and Andreas Fichtner splice optical fibers in the back of a vehicle atop an                                        Icelandic glacier. It is tricky work for cold hands in a harsh environment.                            CREDIT: HILDUR JONSDOTTIR               Fichtner, a geophysicist at the Swiss Federal Institute of Technology in Zurich, is one of a cadre of researchers using fiber optics to take the pulse of our planet. Much of this work is being done in remote places, from the tops of volcanoes to the bottoms of the seas, where traditional monitoring is too costly or difficult. There, in the last five years, fiber optics have started to shed light on seismic rumblings, ocean currents and even animal behaviors. Grímsvötn’s ice sheet, for example, sits on a lake of water thawed by the volcano’s heat. Data from the new cable reveal that the fl

THE FIRST BLACK HOLE IMAGE, TAKE TWO

    From - Sky & Telescope,  By -Camille  M. Carlisle  Edited by - Amal Udawatta, The original image from the Event Horizon Telescope collaboration of the shadow of the black hole M87*  (left) , compared with a new version generated by the PRIMO algorithm  (right) . The tail at the bottom might or might not be a real feature, as it changes quite a bit depending on the analysis. It might be matter swirling around the black hole and falling in. Future work could pin down these kinds of structures and use them to learn more about the material accreting onto the black hole. L. Medeiros (Institute for Advanced Study), D. Psaltis (Georgia Tech), T. Lauer (NSF / NOIRLab), and F. Ozel (Georgia Tech) These two images might look like different things: one a fat, blurry orange doughnut, the other the sinuous noose on the end of a lariat. But they’re two views of the same black hole. This black hole, the leviathan dwelling in the heart of the elliptical galaxy M87, rocketed to worldwide fame i
