The Space Telescope Science Institute (STScI) in Baltimore, Maryland, has appointed Dr. Roeland van der Marel to lead its work on a proposed NASA space telescope that will provide images as sharp as the Hubble Space Telescope, but over a hundred times larger area. The space observatory, called the Wide-Field Infrared Survey Telescope-Astrophysics Focused Telescope Assets (WFIRST-AFTA), is being studied for launch in the mid-2020s, pending program approval by NASA. The telescope will be used to probe the distribution of dark matter and the characteristics of dark energy, measure the abundance and characteristics of planets orbiting other stars, and will provide observations and surveys to study many other astrophysical subjects. STScI is presently the science operations center for the Hubble Space Telescope and the science and mission operations center for the James Webb Space Telescope, scheduled for launch in 2018. Van der Marel joined the STScI staff in 1997. He is also an adjunct professor in the Department of Physics and Astronomy at the Johns Hopkins University in Baltimore, Maryland. He is an expert on black holes and the structure of galaxies.
Why on Earth would somebody seriously entertain the notion that plants have feelings? One possible answer might be that the topic is too seductive to ignore. When Peter Tompkins and Christopher Bird gave in to seduction and published The Secret Lives of Plants: A Fascinating Account of the Physical, Emotional, and Spiritual Relations Between Plants and Man in 1973 they were roundly accused of pseudoscience. But no matter: The book was a hit.
And a hit is blood in the water for scribblers seeking popular subjects to elucidate. Thus the book's swift dismissal by mainstream science hasn't deterred...More
A big brain is a resource-hungry organ, demanding large amounts of energy-rich foods to keep it functioning. Understanding how species like humans and chimpanzees evolved large, energy-hungry brains is a difficult task: explanations must account for not only how the large brain provided an evolutionary advantage, but also how its energy demands could have been met.
A recent paper in PNAS suggests that a bigger brain can help with the energy needs. A group of female chimpanzees was found to show an unexpectedly advanced ability to plan their movements around what they intended to eat for breakfast. The chimps’ movements were tracked over three-quarters of a year, and their behaviors helped them get through three periods of food scarcity.
Previously, researchers suggested that having a consistent source of food was vital for animals with bigger brains. After all, that extra brain tissue is only worthwhile if the animal can eat enough calories to support it. Large-brained primates like chimps have a surprisingly consistent calorie intake despite seasonal fluctuations in their food supplies, which suggests that their intelligence plays an important role in finding food during periods of scarcity.

Hubble has uncovered young, massive, compact galaxies whose raucous star-making parties are ending early. The firestorm of star birth has blasted out most of the remaining gaseous fuel needed to make future generations of stars. Now the party's over for these gas-starved galaxies, and they are on track to possibly becoming so-called "red and dead galaxies," composed only of aging stars. An analysis of 12 merging galaxies is suggesting that energy from the star-birthing frenzy created powerful winds that are blowing out the gas, squelching future generations of stars. This activity occurred when the universe was half its current age of 13.7 billion years.
