Reg3beta Controls Healing Process in the Heart

A new study from the Max Planck Institute details how Reg3beta controls the wound-healing process in the myocardium by attracting immune cells to the infarct tissue. In the wake of a myocardial infarction, parts of the myocardium die and are replaced by scar tissue. The formation and stability of scar tissue is key to the […]

Surface Biosignatures of Exoplanets May Help Detect Extraterrestrial Life

A new catalog of reflectance spectra for a diverse range of pigmented microorganisms may help scientists recognize life on the surface of planets orbiting stars beyond our solar system. A team of astronomers and biologists has recorded the “chemical fingerprints” of 137 different species of microorganism. In future, this could help to recognize life on […]

Merlin Promotes Rapid Wound Healing

New research from the Max Planck Institute details how the protein merlin regulates collective cell movement, promoting effective and rapid wound healing. Cells also follow a herd instinct, and they thereby communicate in a magical collective way. This is because a protein known as merlin, named after the mythical wizard of medieval England, plays an […]

Scientists Identify a Gene for Human Brain Size

A team of researchers has identified for the first time a gene (ARHGAP11B) that is only present in humans and contributes to the reproduction of basal brain stem cells, triggering a folding of the neocortex. About 99 percent of human genes are shared with chimpanzees. Only the small remainder sets us apart. However, we have […]

Bacteria Connect to Each Other Via Nanotubes

New research from the Max Planck Institute shows that some bacteria can form nanotubular structures between single cells that enable a direct exchange of nutrients. It is well-known that bacteria can support each others’ growth and exchange nutrients. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, and their colleagues at the […]

Astronomers Discover Rare Planet

Astronomers have discovered a rare red planet that has the six times the mass of Jupiter, but is about the same size. Two research groups of Heidelberg astronomers have independently of each other discovered a rare planet. The celestial body, called Kepler-432b, is one of the most dense and massive planets known so far. The […]

New Gamma Ray Sources Discovered in Large Magellanic Cloud

The H.E.S.S. telescope system has discovered three extremely luminous gamma-ray sources in the Large Magellanic Cloud. Once again, the gamma ray observatory H.E.S.S. has demonstrated its detecting capabilities: in the Large Magellanic Cloud, the High Energy Stereoscopic System discovered most luminous high-energy gamma-ray sources. These are three objects of different type: a powerful pulsar wind […]

Astronomers Observe Polarized Dust Emission of Two Dark Clouds

A new study shows for the first time that high magnetization sets the stage for the formation of massive stars with 8 solar masses or more. Magnetic fields in massive dark clouds are strong enough to support the regions against collapse due to their own gravity. A study lead by researchers at the Max Planck […]

Why Some Crystals Jump and Others Crumble

A team of researchers has discovered the force that makes the organometallic compound palladium hexafluoroacetylacetonate jump. This thermosalient effect could potentially be applied in artificial muscles and actuators. Crystals are not as stationary as you might think. A crystal of an organometallic compound containing palladium, for example, downright jumps from a hotplate once it reaches […]

Molecule Gives Rise to New Blood Stem Cells in Embryos

A newly published study from the Max Planck Institute details how interferon gamma plays a key role in the development of blood stem cells during the early phase of embryonic development. In the early stage of embryonic development, stem cells with defined tasks, including blood-forming stem cells, gradually emerge. Scientists from the Max Planck Institute […]

Image of the Motion of the Two Electrons in a Helium Atom

Using attosecond-timed laser flashes, a team of physicists has become the first to image and control the motion of the two electrons in a helium atom. Physicists are continuously advancing the control they can exert over matter. A German-Spanish team working with researchers from the Max Planck Institute for Nuclear Physics in Heidelberg has now […]

Dopamine Precursor in Toxic Fruits Increases Fertility

In a new study, researchers from the Max Planck Institute reveal that a dopamine precursor in the toxic fruits of the morinda tree increases fertility in female Drosophila sechellia flies. In the course of evolution, animals have become adapted to certain food sources, sometimes even to plants or to fruits that are actually toxic. The […]

Superconductivity without Cooling

New research details how scientists used an infrared laser pulse to briefly modify the structure of a high-temperature superconductor, removing its electrical resistance at room temperature. Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for […]

Scientists Decode the 3D Structure of the Calcium Channel

Scientists at the Max Planck Institute of Molecular Physiology in Dortmund have decoded the three-dimensional structure of the calcium channel with unprecedented accuracy. Whenever muscles contract, so-called ryanodine receptors come into play. Calcium ions, which are ultimately responsible for the contraction of muscle cells, are released from storage organs and flow through these ion channels. […]

Overzealous Plant Immune System Can Be Deadly

Scientists from the Max Planck Institute for Developmental Biology have now pinpointed the most common culprits for autoimmunity in plants. Plants are under permanent attack by a multitude of pathogens. To win the battle against fungi, bacteria, viruses and other pathogens, they have developed a complex and effective immune system. And just as in humans, […]

A Nanolamp with Lightning-Fast Switch

Scientists have developed a light source which converts an electrical voltage pulse into a light pulse by means of a single molecule, possibly serving as a prototype for nano-components that convert electrical into optical signals with gigahertz frequencies. Information is processed and transmitted by ever-smaller components, sometimes with electrons and sometimes with light. Scientists at […]

Algorithm Can Predict the Evolution of Viruses

Using the branches of a genealogical tree as reference, a team of scientists has developed an algorithm that can predict the evolution of asexual organisms such as viruses or cancer cells. For a long time, prognoses forecasting the evolutionary future of organisms were considered mere speculation. Together with researchers from Cambridge and Santa Barbara, USA, […]
