Genetic risk for schizophrenia is connected to reduced IQ

The relationship between the heritable risk for schizophrenia and low intelligence (IQ) has not been clear. Schizophrenia is commonly associated with cognitive impairments that may cause functional disability. There are clues that reduced IQ may be linked to the risk for developing schizophrenia. For example, reduced cognitive ability may precede the onset of schiz

X-ray tomography on a living frog embryo

Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones. Alternatively, X-rays can also image soft tissues throughout early embryonic development of vertebrates. Related to this, a new X-ray method was presented recently in a Nature article published by a German-American-Russian research team led by KIT.

Bach to the blues, our emotions match music to colors

Whether we're listening to Bach or the blues, our brains are wired to make music-color connections depending on how the melodies make us feel, according to new research from the University of California, Berkeley. For instance, Mozart's jaunty Flute Concerto No. 1 in G major is most often associated with bright yellow and orange, whereas his dour Requiem in D minor is more likely to be linked to d

Gene involved in neurodegeneration keeps clock running

Northwestern University scientists have shown a gene involved in neurodegenerative disease also plays a critical role in the proper function of the circadian clock.

Vicious cycle: Obesity sustained by changes in brain biochemistry

With obesity reaching epidemic levels in some parts of the world, scientists have only begun to understand why it is such a persistent condition. A study in the Journal of Biological Chemistry adds substantially to the story by reporting the discovery of a molecular chain of events in the brains of obese rats that undermined their ability to suppress ap

Stem-cell-based strategy boosts immune system in mice

Raising hopes for cell-based therapies, UC San Francisco researchers have created the first functioning human thymus tissue from embryonic stem cells in the laboratory. The researchers showed that, in mice, the tissue can be used to foster the development of white blood cells the body needs to mount healthy immune responses and to prevent harmful autoimmune reactions.

Fast and painless way to better mental arithmetic? Yes, there might actually be a way

In the future, if you want to improve your ability to manipulate numbers in your head, you might just plug yourself in. So say researchers who report in the Cell Press journal Current Biology on May 16 on studies of a harmless form of brain stimulation applied to an area known to be important for math ability.

Promising treatment for progeria within reach

"This study is a breakthrough for our research group after years of work. When we reduce the production of the enzyme in mice, the development of all the clinical symptoms of progeria is reduced or blocked. We have also studied cultured cells from children with progeria, and can see that when the enzyme is inhibited, the growth of the cells increases by the same mechanism as in mouse cells," says

The developmental genetics of space and time

Albert Erives, associate professor in the University of Iowa Department of Biology, and his graduate student, Justin Crocker, currently a postdoctoral researcher at the Howard Hughes Medical Institute (HHMI) Janelia Farm Research Campus, have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent "morphogen concentra

When green means danger: A stunning new species of palm-pitviper from Honduras

A new species of green palm-pitviper of the genus Bothriechis is described from a seriously threatened cloud forest reserve in northern Honduras. Because of similarity in color pattern and scalation, the new species (Bothriechis guifarroi) was previously confused with other Honduran palm pitvipers. Genetic analysis revealed that the closest relatives of the new species are actually f

Same musicians: Brand new tune

A small ensemble of musicians can produce an infinite number of melodies, harmonies and rhythms. So too, do a handful of workhorse signaling pathways that interact to construct multiple structures that comprise the vertebrate body. In fact, crosstalk between two of those pathways—those governed by proteins known as Notch and BMP (for Bone Morphogenetic Protein) receptors—occurs ove

Mining the botulinum genome

The toxin that causes botulism is the most potent that we know of. Eating an amount of toxin just 1000th the weight of a grain of salt can be fatal, which is why so much effort has been put into keeping Clostridium botulinum, which produces the toxin, out of our food.

Cutting-edge bacteria research leads to more effective treatment of complex infections

Bacteria are life forms, which, like all other life forms, struggle for the best living conditions for themselves. Therefore they will try to avoid getting attacked by the human immune system, and therefore they have developed various ways to protect themselves from the human immune system. When safe from the immune system, they can focus on breeding and multiplying, and if they become numerous en

Bacterium counteracts 'coffee ring effect'

Ever notice how a dried coffee stain has a thicker outer rim, while the middle of the stain remains almost unsoiled? This 'coffee ring effect' also occurs in other materials. Researchers from the Departments of Chemical Engineering and Chemistry at KU Leuven have now discovered how to counteract coffee rings with 'surfactants', i.e. soap. The key to the discovery was not a kitchen towel, but a bac

Cooling ocean temperature could buy more time for coral reefs

Limiting the amount of warming experienced by the world's oceans in the future could buy some time for tropical coral reefs, say researchers from the University of Bristol.
