Humans’ built-in GPS is our 3-D sense of smell

Like homing pigeons, humans have a nose for navigation because our brains are wired to convert smells into spatial information, new research shows. Similar investigations have been conducted on birds and rodents, but this is the first time smell-based navigation has been field-tested on humans. The results evoke a GPS-like superpower one could call an “olfactory positioning system.”

Leaving on a Biofueled Jet Plane

The problem is simple to understand. Molecules of carbon and other greenhouse gases absorb heat. The more greenhouse gases emitted into the atmosphere, the warmer the atmosphere becomes, exacerbating global climate change. Solving the problem is not so simple, especially with regards to aviation – the source of two-percent of the annual greenhouse gas emissions from human activity.

Newfound groups of bacteria are mixing up the tree of life

Jill Banfield, professor of EPS and ESPM, and grad student Christopher Brown discovered a large number of new groups or phyla of bacteria, suggesting that the branches on the tree of life need some rearranging. The more than 35 new phyla equal in number all the plant and animal phyla combined.

Three campus researchers named 2015 Pew scholars

Three early-career researchers at UC Berkeley have been selected as this year’s Pew scholars, a program for investigators of outstanding promise in science relevant to the advancement of human health.

Exiled stars explode far from home

Sharp images obtained by the Hubble Space Telescope confirm that three supernovae discovered several years ago exploded in the dark emptiness of intergalactic space, having been flung from their home galaxies millions or billions of years earlier.
