Helmholtz Association Real time observation of shear waves on the Earth's surface, first direct observation of subducting continental crust during the collision of two continents Earthquake damage to buildings is mainly due to the existing shear waves which transfer their energy during an earthquake to the houses. These shear waves are significantly influenced by the underground and the topography of the surrounding area. Detailed knowledge of the landform and the near-surface...

Door Opened For Solid State Physics By Berlin Researchers

Helmholtz Association Laser processes observed with X-rays on a solid Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable. The methods are used in solid state physics, in the analysis of biological structures, and even art historians have X-rays to thank for many new insights. Now, scientists at the Helmholtz Center Berlin (HZB) have identified yet another area of application. The team around Dr. Martin Beye and Prof....

New AWI Thermal Imaging System Helps Researchers Protect Large Whales From Noise Around The Clock

Helmholtz Association Pile driving during construction of wind farms and the use of airguns when searching for oil and gas unavoidably result in noise pollution in the surrounding area. To ensure that marine mammals are not harmed when in the close vicinity of these activities, regulatory authorities request so-called mitigation measures for their protection. One of such measures requires airguns to be switched off or pile driving to be stopped when whales approach the respective sound...

Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study based on newly developed isotope measurements. This study has now been published in the scientific journal "Science" by scientists from the Universities of Bern and Grenoble and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association....

The end of the last ice age and the processes that led to the melting of the northern and southern ice sheets supply basic information on changes in our climate. Although the maximum size of the ice sheet in the northern hemisphere during the last ice age is relatively well known, there is little reliable data on the dimensions of the Antarctic ice sheet. A publication appearing in the journal “Science” on 1 December now furnishes indications that the two hemispheres attained...

Cancer cells do not grow equally well everywhere in the body. Often, they first create the conditions in which they can grow. Many years ago researchers discovered that solid tumors attract blood vessels to ensure their supply of nutrients by secreting specific factors. Now the immunologist Dr. Uta Höpken (Tumor and Immunogenetics Research Group at the Max Delbrck Center for Molecular Medicine, MDC, Berlin-Buch in the Helmholtz Association) and the hematologist Dr. Armin Rehm...

Investigations of changes in Weddell Sea habitat The research vessel Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association will arrive back at its homeport of Bremerhaven after a seven-month expedition on Friday, 20 May. Nearly 200 researchers from institutes in 15 countries took part in the expedition. The oceanographers on board conducted measurements showing that warming of the water in the deep Weddell Sea continues further. The observations...

How do genes control us? This fundamental question of life still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions in the body for maintaining life. Diseases such as cancer are not only characterized by altered genes, but also by disturbed protein production. But how is protein production controlled? Researchers of the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch of the Helmholtz...

International studies describe current state of the Arctic coasts The coastline in Arctic regions reacts to climate change with increased erosion and retreats by half a meter per year on average. This means substantial changes for Arctic ecosystems near the coast and the population living there. A consortium of more than thirty scientists from ten countries, including researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association and from the...

Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland. These air masses will move east over the next few days, covering parts of Russia and perhaps extend as far south as the Chinese/Russian border. Such excursions of ozone-depleted air may also occur over Central Europe and could reach as far south as the Mediterranean. On an international...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
