UCLA Scientists Use Nanoparticles to Control Molecular Growth of Materials

May 27, 2014

0 Comments

Scientists from UCLA have developed a new process that uses nanoparticles to control molecular growth within the “building block” components of inorganic materials. Growth is a ubiquitous phenomenon in plants and animals. But it also occurs naturally in chemicals, metals and other inorganic materials. That fact has, for decades, posed a major challenge for scientists […]

New Analyses May Imply the Existence of a Dark Matter Particle

March 11, 2014

0 Comments

At a recent physics symposium, scientists from around the world presented several analyses that may imply the existence of a dark matter particle. Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has […]

Study Reveals Why Life in Earth’s Early Oceans Increased in Size

January 24, 2014

0 Comments

A newly published study examined the earliest communities of large multicellular organisms in the fossil record, revealing why life in Earth’s early oceans increased in size. Why did life forms first begin to get larger and what advantage did this increase in size provide? UCLA biologists working with an international team of scientists examined the […]

Scientists Explain the Formation of the Unusual Third Van Allen Radiation Ring

September 23, 2013

0 Comments

UCLA scientists explain the formation of an unusual third radiation ring that briefly appeared between the inner and outer Van Allen radiation belts in September 2012 and persisted for a month. Since the discovery of the Van Allen radiation belts in 1958, space scientists have believed these belts encircling the Earth consist of two doughnut-shaped […]
