Baby Owls Seen Sleeping Like Baby Humans
2013-08-02 08:24:01

AlphaGalileo Foundadtion Baby birds have sleep patterns similar to baby mammals, and their sleep changes in the same way when growing up. This is what a team from the Max Planck Institute for Ornithology and the University of Lausanne found out working with barn owls in the wild. The team also discovered that this change in sleep was strongly correlated with the expression of a gene involved in producing dark, melanic feather spots, a trait known to covary with behavioral and physiological...

Image 1 - Developmental Differences Controlled By Rapidly Evolving Genes
2011-09-19 10:15:28

  Genes essential to producing the developmental differences displayed by social insects evolve more rapidly than genes governing other aspects of organismal function, a new study has found. All species of life are able to develop in different ways by varying the genes they express, ultimately becoming different shapes, sizes, colors and sexes. This plasticity permits organisms to operate successfully in their environments. A new study of the genomes of social insects provides...

By Michael C. Purdy, Washington University in St. Louis A parasite and a virus may be teaming up in a way that increases the parasite's ability to harm humans, scientists at the University of Lausanne in Switzerland and Washington University School of Medicine in St. Louis report this week in Science. When the parasite Leishmania infects a human, immune system cells known as macrophages respond. However, some Leishmania strains are infected with a virus that can trigger a severe response in...

A new study finds that too much, or too little, Internet use may be linked to depression among teens.  The research showed that teens who spent no time online, as well as those who were heavy Internet users, were at increased risk of depression symptoms. Dr. Pierre-Andre Michaud and colleagues at the University of Lausanne in Switzerland surveyed 7,200 participants aged 16 to 20 years old about the frequency of their Internet use. Those who said they were online more than two hours per...

A new computer program shows how the brain's complex fiber tracks mature as we grow up The brain's inner network becomes increasingly more efficient as humans mature. Now, for the first time without invasive measures, a joint study from the Ecole Polytechnique F©d©rale de Lausanne (EPFL) and the University of Lausanne (UNIL), in collaboration with Harvard Medical School, has verified these gains with a powerful new computer program. Reported in the PNAS early online edition last...

Impact didn't lead to mass extinction 65 million years ago, geologists find The enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a paper to be published in the Journal of the Geological Society on April 27, 2009. The crater, discovered in 1978 in northern Yucutan and measuring about 180 kilometers (112 miles) in diameter, records a massive extra-terrestrial...
