Imaging technique gives scientists a look inside cat mummies The atomic number imaging technique is helping researchers see inside the mummies of cats from ancient Egypt without having to remove the wrappings. Scientists hope they can use the new imaging technique to learn more about human mummies. National Geographic Chunks of land along Calif.’s San […]

Birds’ small brains pack big neuron punch Birds’ brains may be small, but they pack more neurons related to intelligence than many mammals with larger brains Researchers used an isotropic fractionator to measure the number of neurons in regions of birds’ brains and found that many songbirds and parrots packed more neurons in their brains […]

Newly found form of CRISPR can break apart RNA Researchers have found that a mouth bacterium can make a form of CRISPR that breaks apart RNA rather than DNA. The finding could have applications for adjusting proteins in cells or targeting cancer cells. The New York Times Photons’ quantum properties could be used to send […]

Unusual underwater structures are geological, not ancient city Uniquely shaped structures found underwater near the Greek island of Zakynthos are naturally occurring geological forms and not the ruins of an ancient city lost to the sea. The circular structures reminiscent of columns, floors and courtyards likely formed about 5 million years ago during the Pliocene […]

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 […]
