Birds Accept And Raise Brood Parasites’ Young For Fear Of Retaliation

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...

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...

Through The Stomach Is The Way To A Chimpanzee's Heart
2014-01-16 13:38:29

Max Planck Institute Chimpanzees who share their food with others have higher levels of the hormone oxytocin in their urine The ability to form long-term cooperative relationships between unrelated individuals is one of the main reasons for human’s extraordinary biological success, yet little is known about its evolution and mechanisms. The hormone oxytocin, however, plays a role in it. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany,...

Bonobos Retain Elevated Thyroid Hormones Well Into Adulthood
2013-12-18 13:23:48

Max Planck Institute Despite the fact that chimpanzees and bonobos share similar starting conditions at birth they develop different behavioral patterns later in life. These differences might be caused by different hormone levels. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Royal Zoological Society of Antwerp in Belgium have analyzed thyroid hormones from urine samples of zoo-living chimpanzees and bonobos. They discovered that bonobos...

Vesta's Hidden Attractions Provided By Dawn
2013-12-17 08:01:02

NASA's Jet Propulsion Laboratory Some beauty is revealed only at a second glance. When viewed with the human eye, the giant asteroid Vesta, which was the object of scrutiny by the Dawn spacecraft from 2011 to 2012, is quite unspectacular color-wise. Vesta looks grayish, pitted by a variety of large and small craters. But scientists at the Max Planck Institute for Solar System Research in Katlenburg-Lindau, Germany, have re-analyzed the images of this giant asteroid obtained by Dawn's...
