3D map shows the adolescent universe Astronomers have pieced together an image of what the adolescent universe looked like using just four hours of telescope observation time, producing a three-dimensional map. The map, millions of light-years across, shows areas of high-density matter that appear to be galaxies as they were just 3 billion years after […]

Yes, I talk to you, even more if you are one of those scientists working with any living being either unicellular or multicellular with sexual dimorphism seared in their chromosomes. Such a question may seem trivial. However, recent findings suggest that it is not so trifling, and that an affirmative answer could have major implications […]

Nitrogen (N) is an essential nutrient for plant growth and most plants require 20-50 g of N taken up by their roots to produce 1 kg of dry biomass. Although N is one of the most abundant elements on earth, agricultural soils are deficient in N and thus, to sustain crops productivity soils require their […]

Breaking waves provide some warmth to surf zones Breaking waves warm the water in the surf, and in some cases may provide more heat than sunshine. Scientists said that in areas like the Pacific Northwest, which have more powerful waves and cloudy skies, heating could be almost three times stronger that what the sun provides […]

An old problem, restated by Martin Gardner in 1959, asked if six cigarettes that can be placed so that each touches the other. Gardner was surprised by fifteen readers discovering that actually seven cigarettes can be arranged with that condition . Some years later, in 1968, Littlewood raised the question if it possible in 3-space […]

It is possible that we know more about the cause of skin cancer than about any other type of cancer. The link between sun exposure (UV radiation) and the development of skin cancer is solidly established. And yet, the incidence of this disease is increasing year after year with a steepest slope than any other […]

Ancient Antikythera wreckage holds treasure trove of artifacts Researchers excavating the 2,000-year-old wreckage of the Antikythera in Greece have found a treasure trove ancient goods. “The evidence shows this is the largest ancient shipwreck ever discovered,” said marine archaeologist Brendan Foley. The wreckage was discovered more than a century ago but the current excavation has […]

However, it could be possible that this is not completely […]
