Credit: Portrait of Louis Daguerre (1787-1851); via Wikipedia Louis Daguerre Louis Daguerre, a French artist and inventor, is widely regarded as one of the pioneers of photography. In the early 19th century, Daguerre developed the daguerreotype process, an early photographic technique that involved exposing a silver-coated copper plate to light. This process produced highly detailed and one-of-a-kind images. On January 7, 1839, Daguerre announced his invention to the French Academy of Sciences, and it was subsequently made available to the public. In the same year, Daguerre set up a ma ..read more

Credit: Getty Images Dark Energy Spectroscopic Instrument reveals evidence of mass star migration into a galaxy other than the Milky Way Galaxies grow and evolve by forging new stars and merging with other galaxies through aptly named "galactic immigration" events. The archaeology of such events, uncovered by studying the motions of individual stars throughout a galaxy and its extended halo of stars and dark matter, had been possible only in the Milky Way. Now, an international team of researchers has uncovered striking new evidence of a large galactic immigration event in the Andromed ..read more

Much of what people do on Earth today relies heavily on what's happening high above their heads – from monitoring wildfires, deforestation and sea-surface temperatures to enabling connections to new mobile technologies like 5G in hard-to-reach areas. A recent wave of cheaper, miniature satellites being sent into low orbits of 500 to 1 000 kilometres above Earth by the likes of Elon Musk's SpaceX a ..read more

(Photo by David Levenson/Getty Images) Rupert Sheldrake Rupert Sheldrake is one of the most controversial figures in contemporary science. As a matter of fact, many would disagree with calling him a scientist at all and would prefer the term pseudo-scientist. He is not accepted by the scientific mainstream and is considered a New Age scientist. Rupert Sheldrake was born on June 28, 1942. He is best known for his controversial theories in the fields of biology and parapsycho ..read more

Now, the work of U.S. National Science Foundation-supported researchers at Gladstone Institutes has shed new light on this phenomenon. The scientist ..read more
