Relationships are difficult and most of us probably think at some point that communicating positively with our partner when discussing stressful issues, like home finances, is an impossible task. What if there was a safe way to take the "edge" off these discussions? The biology of human social relationships is just beginning to emerge as groundbreaking research on social cognition conducted in animals is now informing research in humans.

Biology

A growing body of basic animal research and studies of abused and neglected children provide a strong basis of support for the hypothesis that individuals with particular genotypes are at greater risk for depression, anxiety disorders, and problems with the abuse of alcohol and other substances. These gene-by-environment interactions are so powerful that some might assume that these genotypes identify people who are predestined to negative life outcomes.

Nature is full of mutually beneficial arrangements between organisms—like the relationship between flowering plants and their bee pollinators. But sometimes these blissful relationships have a dark side, as Harvard biologist Megan Frederickson describes in an article for the May issue of The American Naturalist.

The Lost World, Sir Arthur Conan Doyle's account of an isolated community of dinosaurs that survived the catastrophic extinction event 65 million years ago, has no less appeal now than it did when it was written a century ago. Various Hollywood versions have tried to recreate the lost world of dinosaurs, but today the fiction seems just a little closer to reality. New scientific evidence suggests that dinosaur bones from the Ojo Alamo Sandstone in the San Juan Basin, USA, date from after the extinction, and that dinosaurs may have survived in a remote area of what is now New Mexico and Colorado for up to half a million years. This controversial new research, published today in the journal Palaeontologia Electronica, is based on detailed chemical investigations of the dinosaur bones, and evidence for the age of the rocks in which they are found.

New research published today (Monday April 27) from the University of Leicester and University Hospitals of Leicester NHS Trust warns of a six-month time lag before effective vaccines can be manufactured in the event of a pandemic flu outbreak.

Molecular & Cell Biology

A defining hallmark of Alzheimer's disease is the accumulation of the amyloid β protein (Aβ), otherwise known as "senile plaques," in the brain's cortex and hippocampus, where memory consolidation occurs. Researchers at the University of California, San Diego School of Medicine have identified a novel protein which, when over-expressed, leads to a dramatic increase in the generation of Aβ. Their findings, which indicate a potential new target to block the accumulation of amyloid plaque in the brain, will be published in the May 1 issue of the Journal of Biological Chemistry.

An influenza vaccine that protects against death and serious complications from different strains of flu is a little closer to reality, Saint Louis University vaccine researchers have found.

Microbiology

For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA. A new study from the University of Illinois disproves that.

Most people are expert readers, but it is something of an enigma that our brain can achieve expertise in such a recent cultural invention, which lies at the interface between vision and language. Given that the first alphabetic scripts are thought to have been invented only around four to five thousand years it is unlikely that enough time has elapsed to allow the evolution of specialized parts of the brain for reading. While neuroimaging techniques have made some progress in understanding the neural underpinning of this essentially cultural skill, the exact unfolding of brain activity has remained elusive.

Autoimmune diseases have long been regarded as illnesses in which the immune system creates autoantibodies to attack the body itself. But, researchers at the California non-profit Autoimmunity Research Foundation (ARF) explain that the antibodies observed in autoimmune disease actually result from alteration of human genes and gene products by hidden bacteria.

Our bodies' tissues need continuous irrigation and drainage. Blood vessels feeding the tissues bring in the fluids, and drainage occurs via the lymphatic system. While much is known about how blood vessels are built, the same was not true for lymph vessels. Now though, Norrmén et al. have identified two of the lead engineers that direct drainage construction in the mouse embryo.

Biology

It is said that each of us marches to the beat of a different drum, but new Stanford University research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning. These rhythms don't appear to be working correctly in such diseases as schizophrenia and autism, and now two papers due to be published online this week by the journals Nature and Science demonstrate that precisely tuning the oscillation frequencies of certain neurons can affect how the brain processes information and implements feelings of reward.

Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. The insight ultimately could lead to a cost-effective and energy-efficient strategy for turning biomass into alternative fuels.

AIDS & HIV

Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled. The reason? According to new findings from a team of researchers from the California Institute of Technology (Caltech), it's at least partly due to the fact that our body's natural HIV antibodies simply don't have a long enough reach to effectively neutralize the viruses they are meant to target.

School-aged children who witness violence in urban communities show symptoms of post-traumatic stress. They also suffer physiological effects with a disruption to their normal cortisol production pattern during the day, which may have long-term negative effects on their health. According to Dr. Shakira Franco Suglia, from the Harvard School of Public Health, and her team lead by Dr. Rosalind J. Wright from Brigham and Women's Hospital, Harvard Medical School in Boston, USA, because these children are not diagnosed with post-traumatic stress disorder, these abnormal physiological symptoms are unlikely to be picked up by their doctors. The study1 has just been published online in Springer's International Journal of Behavioral Medicine.

The human genome complete sequencing project in 2003 revealed the enormous instruction manual necessary to define a human being. However, there are still many unanswered questions. There are few indications on where the functional elements are found in this manual. To explain how we develop, scientists will have to decode the entire network of biological complexes that regulate development. One of the biggest challenges is to analyse the key proteins involved in the development of a human being, namely the proteins that bind to DNA. "If the genome provides the recipe to define a human being, the DNA proteins are the "chefs" that cook it", describes Herbert Auer, manager of the Functional Genomics Facility at the Institute for Research in Biomedicine (IRB Barcelona) and co-organizer, together with Erich Grotewold, at the Ohio State University, of the Barcelona Biomed Conference, "The DNA proteome". Invited by IRB Barcelona and the BBVA Foundation, twenty-one authorities in the field of genomics present their recent work on 20, 21 and 22 April at the "Institut d'Estudis Catalans", in Barcelona.
