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 […]

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, […]

Researchers Develop Nano Devices That Can be Propelled Through Media Similar to Bodily Fluids

Scientists from the Max Planck Institute have constructed swimming bodies that are small enough to be used in bodily fluids or even individual cells, and they are able to navigate through complex biological fluids. In the 1966 movie Fantastic Voyage, a submarine complete with crew is shrunk in size so that it can navigate through […]

Chimpanzees Plan Their Breakfast Time and Location

New research from the Max Planck Institute for Evolutionary Anthropology shows that wild chimpanzees plan their breakfast time, type and location when food supplies are short. How do our close relatives, the chimpanzees, acquire sufficient food when times are lean? By studying wild chimpanzees in the Taï National Park in Côte d’Ivoire researchers of the […]

A 3D Map of the Adolescent Universe

Using a new technique similar to x-ray computer-tomographic imaging, a team of astronomers has created the first three-dimensional map of the adolescent Universe – just 3 billion years after the Big Bang. Using extremely faint light from galaxies 10.8-billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice […]

Study Reveals Climate Change Alters the Ecological Impacts of Seasons

New research from the Max Planck Institute for Developmental Biology and the University of Wyoming details how changes in temperature variability across the globe are altering the environment. If more of the world’s climate becomes like that in tropical zones, it could potentially affect crops, insects, malaria transmission, and even confuse migration patterns of birds […]
