Interstellar Molecules Are Branching Out
2014-09-27 08:50:36

Max Planck Institute Scientists from the Max Planck Institute for Radio Astronomy (Bonn, Germany), Cornell University (USA), and the University of Cologne (Germany) have for the first time detected a carbon-bearing molecule with a "branched" structure in interstellar space. The molecule, iso-propyl cyanide (i-C3H7CN), was discovered in a giant gas cloud called Sagittarius B2, a region of ongoing star formation close to the center of our galaxy that is a hot-spot for molecule-hunting...

Region Of The Brain Discovered That Enables Children To Overcome Emotional Self-centeredness As They Mature
2014-05-28 10:18:06

Max Planck Institute Children are more egocentric than adults. Scientists from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig  have demonstrated for the first time that children are also worse at putting themselves in other people’s emotional shoes. According to the researchers, the supramarginal gyrus region of the brain must be sufficiently developed in children for them to be able to overcome their egocentric take on the world. When little Philip...

Birds Accept And Raise Brood Parasites’ Young For Fear Of Retaliation
2014-04-18 14:50:57

Max Planck Institute If a restaurant owner fails to pay the protection money demanded of him, he can expect his premises to be trashed. Warnings like these are seldom required, however, as fear of the consequences is enough to make restaurant owners pay up. Similarly, mafia-like behavior is observed in parasitic birds, which lay their eggs in other birds’ nests. If the host birds throw the cuckoo’s egg out, the brood parasites take their revenge by destroying the entire nest....

Liberia Is Home To The Second Largest Chimpanzee Population In West Africa
2014-04-10 12:30:18

Max Planck Institute When Liberia enters the news it is usually in the context of civil war, economic crisis, poverty or a disease outbreak such as the recent emergence of Ebola in West Africa. Liberia’s status as a biodiversity hotspot and the fact that it is home to some of the last viable and threatened wildlife populations in West Africa has received little media attention in the past. This is partly because the many years of violent conflict in Liberia, from 1989 to 1997 and from...

Sleep is essential for human health. But with increasing age, many people experience a decline in sleep quality, which in turn reduces their quality of life. In a new study publishing April 1 in the Open Access journal PLOS Biology, Scientists at the Max Planck Institute (MPI) for Biology of Ageing in Cologne have investigated the mechanisms by which ageing impairs sleep in the fruit fly. Their findings suggest that age-related sleep decline can be prevented and might even be reversible....

Jumping bristletail Lepismachilis y-signata
2014-03-30 03:00:54

Max Planck Institute for Chemical Ecology Odorant receptors of recent insects evolved long after insects migrated from water to land. An insect’s sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at the Max Planck Institute for Chemical Ecology, many proteins involved in the highly sensitive odor perception of insects emerged...

Flowering Plants Need Sugar Transporter SWEET9 For Nectar Production
2014-03-17 10:58:21

Max Planck Institute for Chemical Ecology Evolution is based on diversity, and sexual reproduction is key to creating a diverse population that secures competitiveness in nature. Plants as largely immobile organisms had to solve a problem: they needed to find ways to spread their genetic material beyond individual flowers. To make sure that flying pollinators such as insects, birds and bats come to the flowers to pick up pollen, plants evolved special organs, the nectaries, to attract and...

Brake For Spinning Molecules
2014-03-13 15:39:05

Max Planck Institute The precise control of the rotational temperature of molecular ions opens up new possibilities for laboratory-based astrochemistry Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in Denmark and the Max Planck Institute for Nuclear Physics in Heidelberg, discovered an efficient and versatile way of braking the rotation of molecular ions. The spinning speed of...

Brain Activity During Slow-Wave-Sleep Differs Between Mammals And Birds
2014-03-05 10:40:23

Max Planck Institute When we drift into deep slow-wave sleep (SWS), waves of neuronal activity wash across our neocortex. Birds also engage in SWS, but they lack this particular brain structure. Researchers from the Max Planck Institute for Ornithology in Seewiesen, Germany together with colleagues from the Netherlands and Australia have gained deeper insight into the sleeping avian brain. They found complex 3D plumes of brain activity propagating through the brain that clearly differed...

Researchers Discover Gene Responsible For Dissected Leaves
2014-02-14 13:19:31

Max Planck Institute Arabidopsis thaliana lost the RCO gene over the course of evolution and thus forms simple leaves Spinach looks nothing like parsley, and basil bears no resemblance to thyme. Each plant has a typical leaf shape that can differ even within the same family. The information about what shape leaves will be is stored in the DNA. According to researchers at the Max Planck Institute for Plant Breeding Research in Cologne, the hairy bittercress (Cardamine hirsuta) has a...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
