Using Zebrafish to Decipher the Roles of Genes Associated with Autism

In an effort to identify the genes involved and develop treatments for human brain disorders, such as autism, researchers have taken a new approach. By using zebrafish, the scientists studied a group of about two dozen genes known to be either missing or duplicated in about 1 percent of autistic patients, finding that nearly all […]

European Cave Paintings Older Than Previously Thought, Might Have Been Painted by Neanderthals

cave-painting-spain-altamiral-claviform

Some European cave paintings are older than previously thought, implying that Neanderthals might have been their creators rather than Homo sapiens. It’s not yet certain, but some of the earliest paintings that were dated raise interesting questions, including whether Neanderthals were painters. At a press conference on June 13th, archaeologist João Zilhão stated that it […]

CO2 Snow Particles on Mars are About the Size of Red Blood Cells

Researchers have determined the size of CO2 snow particles on Mars

By using data gathered from instruments onboard the Mars Global Surveyor and Mars Reconnaissance Orbiter, scientists at MIT have calculated the size of snow particles in clouds at both Martian poles, finding that snow particles at both poles are about the size of a red blood cell with particles in the south being slightly smaller […]

Monkeys Cured of Ebola Zaire Virus with Antibody Cocktail

ebola-virus-cdc

A cocktail of three antibodies has been able to cure monkeys infected with the Ebola virus if administered 24 hours or more after exposure. This could imply that a future treatment for humans could be possible. Some of the variants of the Ebola virus kill up to 90% of infected patients, and currently, most treatment […]

Carbon Increases Oil Production from Algae

cultures of algae that were shown to increase oil production in response to excess carbon.

By feeding algae more carbon, scientists at the Brookhaven National Laboratory increased the microbes’ overall metabolism, resulting in increased oil production as the organisms continued to grow. Upton, New York — Overturning two long-held misconceptions about oil production in algae, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory show that ramping up the […]

Biochemical Systems that Modulate the Levels of Plant Hormones

In plants, hormone signaling substitutes for an immune system

An international team of scientists have begun to put a molecular face on the biochemical systems that modulate the levels of plant hormones to defend the plant from attack or changes in growing conditions. Science has known about plant hormones since Charles Darwin experimented with plant shoots and showed that the shoots bend toward the […]

NuSTAR to Scan Supernovas and Help Improve Computer Simulations

supercomputer model of a spinning core-collapse supernova

Using the Nuclear Spectroscopic Telescope Array, astrophysicists will scan debris from supernovas to better understand how they work and use that information to figure out why supercomputer simulations fail to produce an explosion. Somewhere in the Milky Way, a massive old star is about to die a spectacular death. As its nuclear fuel runs out, […]

BaBar Data Suggests Possible Flaws in the Standard Model

Initial results from BaBar data suggest that a particular type of particle decay called “B to D-star-tau-nu” happens more often than the Standard Model says it should. Menlo Park, California — Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the […]

Quantum Information is Preserved for Longer than a Second at Room Temperature

Quantum information is preserved in an artificial diamond

A team of scientists successfully stored a quantum bit in a diamond crystal for more than a second at room temperature, an improvement of almost thousand-fold, and believe that the lifetime of the qubit can be increased to a maximum of 36 hours. Credit cards which are completely fraud-proof and passports which cannot be forged: […]

Though separated by tens of millions of light-years, a new image from NASA’s Hubble Space Telescope shows a pair of galaxies that seem to be intertwined. NASA’s Hubble Space Telescope shows a rare view of a pair of overlapping galaxies, called NGC 3314. The two galaxies look as if they are colliding, but they are […]

Ancient Antarctica Was Much Warmer and Wetter than Previously Suspected

In an effort to better understand what the future of climate change may look like, a team of scientists examined plant leaf wax remnants in sediment core samples taken from beneath the Ross Ice Shelf, finding that ancient Antarctica was much warmer and wetter than previously suspected. Pasadena, California — A new university-led study with […]

Ultrasound Improvements May Help Monitor the Progression of Disease

By producing consistent images that can compensate for body motions and by providing a way to map the exact location on the skin where one reading was taken, MIT researchers have made sonography a much more precise tool, possibly allowing doctors to accurately track the development of medical conditions and monitor the progression of diseases. […]
