Ancient Phoenician’s genome sequenced A Phoenician who lived 2,500 years ago near Carthage had European ancestors, according to researchers who sequenced his mitochondrial genome after collecting DNA from his remains. The Phoenician’s ancestry was traced back to the European haplogroup U5b2cl, connected to the North Mediterranean and possibly the Iberian Peninsula. Seeker Protein linked to […]

Hubble image offers detailed view of Mars A detailed image of Mars has been taken by the Hubble Space Telescope as the Red Planet moves into opposition with Earth. The image depicts many of Mars’ geological features, such as mountains, plains and ice caps. Mars is in opposition today! Space.com Urban bees mostly dine on […]

Earth-sun magnetic field interactions seen by NASA space probes Explosive storms spawned by interactions between the magnetic fields of Earth and the sun can endanger satellites, spacecraft and astronauts in space, as well as power grids on Earth. Now, a fleet of NASA spacecraft has for the first time directly witnessed the mysterious way in […]

Venus flytraps’ predatory ways may have roots in defense The genes that allow Venus flytraps to be carnivores may come from defensive mechanisms carried over from their non-insect-eating ancestors. Researchers found that gene expression patterns shift radically when prey steps into the plants’ traps, signaling digestive enzymes along the same protein paths used to help […]

Nonhuman primates may be involved in Zika transmission Scientists who collected biological samples from 15 wild marmosets and eight pet capuchin monkeys plus one free-ranging capuchin in Brazil found four marmosets and three capuchins had been infected with the Zika virus. The Scientist Cosmic-particle technology opens window into Bent Pyramid New cosmic-particle technology has allowed […]

Dali painting used in study of how brain processes information Scientists used a painting by Salvador Dali to help them discover how the brain processes information. Researchers asked study participants to examine Dali’s 1940 work “Slave Market with the Disappearing Bust of Voltaire,” which is visually ambiguous. “We found very early on … that the […]

First images from Japan’s long-delayed Venus probe revealed Japan’s Akatsuki spacecraft has finally begun sending back images from Venus after an unexpected five-year orbit around the sun. Images show a strange curved shape moving across Venus’ atmosphere as well as clouds of sulfuric acid. The Japan Aerospace Exploration Agency rescued the craft and put it […]

Neanderthal Y chromosome missing in modern humans The Neanderthal Y chromosome hasn’t been found in modern humans, suggesting it is extinct. Researchers found dissimilarities in the Neanderthal Y chromosome’s immunity genes that could have caused miscarriages. BBC Clouds may not help keep global temperatures down Clouds’ cooling power may not be as great as climate […]

Photos reveal possible planet-forming disk around young star Photos taken by the Atacama Large Millimeter/submillimeter Array, or ALMA, appear to show the birth of an alien planet similar to Earth along with other nascent worlds. The photos reveal a disk surrounding the star TW Hydrae that appears to have planets starting to form within it […]

Synthetic cell with just 473 genes developed A synthetic cell containing just 473 genes, the smallest number of genes in any independent life form that exists in nature, has been developed by a team of scientists led by genomics expert Craig Venter. The functions of 149 of the genes in JCVI-syn3.0 are unknown. Nature Vivid […]
