Adam Frank: Looking back 100, 1000 or 10,000 years, it became clear to me that time in cosmology (be it of the scientific or mytho-religious variety) has always been tightly braided with the human experience of time.
The popping of champagne corks may have subsided since scientists presented convincing evidence for the existence of the long-sought Higgs boson, but the work has just begun for theoretical particle physicists, who are revelling in the biggest glut of data they’ve had since the 1990s. Many are working evenings and weekends to interpret the results,…
A consortium of scientists announced they had made major progress in deciphering the genome of bread wheat, a vital crop whose DNA is notoriously complex. Publishing in the journal Nature, they said they had analysed between 94,000 and 96,000 genes in bread wheat (Triticum aestivum). The plant’s genome is nearly five times as big as…
Rep. Todd Akin (R-MO), his party’s candidate in the Missouri Senate race to unseat Democrat Claire McCaskill, has quickly attempted to retract his comment that in cases of “legitimate rape,” women have biological defenses against pregnancy. “I misspoke,” he claimed in a carefully crafted statement. After all, cleaning up the mess after the candidate not…
Physically fit frogs have faster-changing genomes, according to a study of poison frogs from Central and South America. Stretches of DNA generally accumulate changes over time, but the rate at which this occurs varies between species. Biologists have, in the past, tried to explain why some species have faster-changing genomes than others by focusing on…
There is an optimistic view of the unprecedented migration we are witnessing from rural to urban areas, and it’s that cities could offer the biggest hope for the survival of other species and ecosystems in the Anthropocene. Cities are entirely shaped and created by humans to protect and separate them from the natural world, allowing…
Scientists at Karolinska Institutet in Sweden have identified two molecules that play an important role in the survival and production of nerve cells in the brain, including nerve cells that produce dopamine. The discovery, which is published in the journal Nature Chemical Biology, may be significant in the long term for the treatment of several…
