Promising results raise hope for cancer breakthrough: T cells could be tweaked to kill a range of cancers.
In a potential breakthrough in cancer research, scientists at the University of Pennsylvania have genetically engineered patients’ T cells — a type of white blood cell — to attack cancer cells in advanced cases of a common type of leukemia.
Two of the three patients who received doses of the designer T cells in a clinical trial have remained cancer-free for more than a year, the researchers said.
The Better Angels of Our Nature: Why Violence Has Declined by Steven Pinker
Many people think we live in the most violent age ever. But this book shows the opposite is true: violence has been diminishing for millennia. For most of history, war, slavery, infanticide, child abuse, pogroms, gruesome punishments, and genocide were ordinary features of life. But today, these have all dwindled and are widely condemned.
A new law recognizing the land ownership rights of Peru’s native inhabitants sets an important regional precedent.
In February, after a legal battle lasting nearly two decades, little-known indigenous communities in Ecuador’s Amazon region won a multi-billion dollar landmark ruling against the oil giant Chevron. The company was accused of polluting a large part of the Amazon basin by dumping billions of litres of chemical-laden materials, which campaigners said destroyed crops, killed livestock and increased cancer rates among the local population.
I dare you to gaze at an aurora and tell me that life sucks.
Explanation: September’s equinox arrives today at 0905 UT. As the Sun crosses the celestial equator heading south, spring begins in the southern hemisphere and autumn in the north. And though the seasonal connection is still puzzling, both spring and autumn bring an increase in geomagnetic storms. So as northern nights grow longer, the equinox also heralds the arrival of a good season for viewing aurora. Recorded earlier this month, these curtains of September’s shimmering green light sprawl across a gorgeous night skyscape. In the foreground lies Hidden Lake Territorial Park near Yellowknife, Northwest Territories, Canada. Calm water reflects the aurora, with bright star trails peering through the mesmerizing sky glow. Of course, shining at altitudes of 100 kilometers or so, planet Earth’s auroras are visible from space.
