Study Shows Human Brain Development is Divided into Three Major Phases

Human Brain Develops with an Exquisitely Timed Choreography

In a newly published study, researchers analyzed gene expression in human and macaque monkey neocortex, finding that human neocortical development is divided into three major phases. The human brain develops with an exquisitely timed choreography marked by distinct patterns of gene activity at different stages from the womb to adulthood, Yale researchers report in the […]

Spitzer Measures the Physical Properties of NEO 2009BD

Spitzer Measures NEO 2009BD

Using the Spitzer Space Telescope, a new study measures the physical properties of NEO 2009BD. Asteroids (or comets) whose orbits bring them close to the earth’s orbit are called near Earth objects. Some of them are old, dating from the origins of the solar system about four and one-half billion years ago, and expected to […]

AIM Monitors Electric-Blue Noctilucent Clouds over Antarctica

Electric Blue Clouds Appear over Antarctica

New data from NASA’s AIM spacecraft show a vast bank of noctilucent clouds blanketing Antarctica. Data from NASA’s AIM spacecraft show that noctilucent clouds are like a great “geophysical light bulb.” They turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days. News […]

Astronomers Discover a Gamma-Ray Burst without a Radio Afterglow

Exploding Stars Switch Off Radio Transmissions before Collapsing into a Black Hole

In new study, astronomers detail the discovery of a gamma-ray burst without a radio afterglow. Astronomers led by a Curtin University researcher have discovered a new population of exploding stars that “switch off” their radio transmissions before collapsing into a Black Hole. These exploding stars use all of their energy to emit one last strong […]

Infrared Dark Clouds Reveal Why Some Stars are Bigger than Others

Infrared Dark Clouds Reveal Why Some Stars are Bigger than Others

Using the Atacama Large Millimeter/submillimeter Array telescope, astronomers surveyed the cores of some of the darkest, coldest, and densest clouds in our Galaxy to find out why some stars are bigger than others. Massive stars – those at least 8 times the mass of our Sun – present an intriguing mystery: how do they grow […]

A New Technique for Determining the Mass of Exoplanets

Researchers Develop a New Technique for Determining the Mass of Exoplanets

MIT researchers have developed a new technique for determining the mass of exoplanets using only their transit signal, helping researchers determine the mass of exoplanets that are not measurable in any other way. To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system. To determine if any of […]
