Gigantic black holes threw their weight around in the early universe
In a series of experiments with sleeping mice, researchers at the Duke University Medical Center have shown that the part of the brain that processes scents is indeed a key part of forming long-term memories, especially involving other individuals.

The means by which proteins provide a ‘border control’ service, allowing cells to take up chemicals and substances from their surroundings, whilst keeping others out, is revealed in unprecedented molecular detail for the first time, in the journal Science.

A classic experiment proving amino acids are created when inorganic molecules are exposed to electricity isn’t the whole story, it turns out. The 1953 Miller-Urey Synthesis had two sibling studies, neither of which was published. Vials containing the products from those experiments were recently recovered and reanalyzed using modern technology. The results are reported in [...]

Scientists from around the globe have formed the International Human Microbiome Consortium, an effort that will enable researchers to characterize the relationship of the human microbiome in the maintenance of health and in disease.
Researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture. Chemists combined electrically conductive plastic with metals including molybdenum and titanium to create the hybrid material.

Images of white men predominate in western anatomy textbooks, which present them as a “universal model” of the human being. This is the main conclusion of a study that has analysed 16,329 images from 12 manuals currently recommended by 20 of the most prestigious universities in Europe, the United States and Canada.

About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. This object, known as a pulsar, is the first one known to “blink” only in gamma rays, and was discovered by the Large Area Telescope onboard NASA’s Fermi Gamma-ray Space Telescope.

A new screening method can be used to detect the chromosomal abnormalities most commonly associated with autism spectrum disorders. By screening for genetic defects associated with various kinds of cognitive impairment, the approach will help clinicians identify the underlying causes of some patients’ autism spectrum disorders.
