Hubble Discovers a Fifth Moon Orbiting Pluto

A New Moon Has Been Discovered Orbiting Pluto

By Maria Panagiotidi A fifth moon was discovered orbiting Pluto by a team of astronomers using NASA’s Hubble space Telescope. The icy dwarf planet Pluto has four other known moons, the largest being Charon which was discovered in 1978 at the United States Naval Observatory in Washington, D.C. Hubble observations in 2006 uncovered two additional small moons, Nix…

Scientists discover bees that can reverse brain aging

By Maria Panagiotidi Scientists at Arizona State University have discovered that older honey bees can reverse brain aging when they take on nest responsibilities typically handled by much younger bees. This finding could provide alternative interventions for the treatment of age-related dementia. Current research focuses mainly on potential new drug treatments. The study was published in…

First Steps Toward Emergence of Life Theory

By Stephen Sadler What turned a primordial mixture of amino acids and proteins into the first organized, self-replicating unit? What was it that breathed the vital breath into a collection of inanimate chemical building blocks, giving rise to an unbroken chain of evolution stretching three and a half billion years into the future and culminating in…

Researchers led by Evgeny Katz, the Milton Kerker Chaired Professor of Colloid Science at Clarkson University, have implanted a biofuel cell in a living snail. This is the first incidence of an implanted biofuel cell continuously operating in a snail and producing electrical power over a long period of time using the snail’s physiologically produced glucose as a fuel.

Scientists Implant Biofuel Cell in Living Snail

By Maria Panagiotidi Researchers led by Evgeny Katz, the Milton Kerker Chaired Professor of Colloid Science at Clarkson University, have implanted a biofuel cell in a living snail. Their findings were published in the Journal of The American Chemical Society. The “implanted battery” can generate electrical power for several months driven by glucose, which is…

Simulation of a black hole orbited by two accretion discs, after evolving for approximately 10 orbits. The structure of the two original discs can be seen in blue, whereas the white disc near the centre is formed of gas that has collided and fallen in, before restabilising at a smaller radius.

Greedy Black Holes Eat Two Meals at a Time

By Stephen Sadler Researchers at the University of Leicester may have solved a long-standing mystery in astrophysics, namely: how do black holes grow so massive? In a recent paper in the journal Notes of the Royal Astronomical Society, Christopher Nixon and Andrew King from the University of Leicester, along with their collaborator Daniel Price from Monash…

Eating smelly foods could aid weight loss

By Holly Rogers Strongly scented foods encourage people to take smaller bites, a method commonly thought to help dieters with portion control, say researchers from Wageningen University, Netherlands. Participants in the study were given control of how much custard they were served by pushing a button, as they were repeatedly exposed to different scents. The study…

Anxiety enhances sense of smell

By Maria Panagiotidi Anxious people have a heightened sense of smell, when it comes to sniffing out a threat, according to a new study by Elizabeth Krusemark and Wen Li from the University of Wisconsin-Madison in the US. The results of their study will be published online in the journal Chemosensory Perception. The sense of…
