Researchers image complete nervous system in real time
Plant and Animal Science Neuroscientist Alipasha Vaziri of the University of Vienna and his colleagues have for the first time imaged all of the neurons firing in a living organism, the nematode worm Caenorhabditis elegans. They engineered C. elegans so t ...
Scientists discover why an octopus never gets entangled
Plant and Animal Science Guy Levy, a neuroscientist at the Hebrew University of Jerusalem, and his team studied how an octopus avoids latching onto itself. They cut off an octopus’s arm and subjected it to a series of tests, and found that octopus arms ha ...
Scientists resolve the mystery of magnetar formation
Earth and Planetary Science A team of researchers headed by Simon Clark reported that they have found the "runaway star" that caused the Milk Way Galaxy's only magnetar—a rare type of neutron star that is highly dense and extremely magnetic ...
First semi-synthetic organism with 'alien' DNA created
Biochemistry, Genetics, and Molecular Biology Researchers from the Scripps Research Institute in La Jolla, Calif., created a semi-synthetic microbe, a genetically modified E. coli bacterium. They created two new nucleotides, X and Y, and fused them into t ...
Brain size does matter when it comes to self-control among animals
Psychology and Neuroscience In a large-scale collaborative effort, scientists used two problem-solving tasks to investigate the evolution of self-control among animals. The study involved 36 species of mammals and birds. The scientists found that the spec ...
Heart disease can be prevented by altering fat metabolism
Medicine, Health, and Nursing In a recent study, scientists were able to identify and arrest the action of a single molecular agent that affects the body’s ability to properly use, transport, and rid itself of cholesterol. This agent, called glycosphingol ...
Researchers discover the earliest ancestor of land herbivores
Plant and Animal Science The discovery of a fossilized juvenile skeleton of Eocasea martini has helped researchers understand how carnivores transitioned into herbivores for the first time on land. The 300-million-year old skeleton is less than 20 cm long ...
Three-million-year-old landscape beneath Greenland Ice Sheet
Earth and Planetary Science Scientists have discovered an ancient tundra landscape under the Greenland Ice Sheet, preserved for 2.7 million years. This discovery provides strong evidence that the Greenland Ice Sheet has persisted much longer than previous ...
Artificial ‘biospleen’ device to treat sepsis
Biochemistry, Genetics, and Molecular Biology Researchers at Wyss Institute for Biologically Inspired Engineering in Boston, Massachusetts, have developed a device that acts like the spleen to rid the body of infection and toxins. The artificial ‘biosplee ...
Induced pluripotent stem cell treatment set for its first human trial
Biochemistry, Genetics, and Molecular Biology Masayo Takahashi, an ophthalmologist at the RIKEN Center for Developmental Biology (CDB) in Kobe, is set to treat a human patient with induced pluripotent stem (iPS) cells. iPS cells, unlike embryonic stem cel ...
