Researchers Simulate the Formation of Massive Stars from Turbulent Molecular Clouds

November 19, 2013

0 Comments

Using the Pleiades supercomputer at the NASA Advanced Supercomputing (NAS) facility, researchers perform large-scale supercomputing simulations of massive stars forming from the collapse of giant, turbulent molecular clouds. In their quest to understand the origins of stars and galaxies in our universe, astrophysicists use supercomputers to model extremely complex phenomena on an immense scale. Massive […]

Astronomers Estimate One in Five Sol-Like Stars Have Planets Conducive to Life

November 5, 2013

1 Comment

Based on a statistical analysis of all the Kepler data, astronomers now estimate that one in five stars like our Sun have planets about the size of Earth and a surface temperature conducive to life. Berkeley — NASA’s Kepler space telescope, now crippled and its four-year mission at an end, nevertheless provided enough data to […]

Inactivating AGPS Enzyme Reduces Tumor Growth, Cripples Cancer Cells

August 27, 2013

1 Comment

In a newly published study, researchers tested the effects of reducing ether lipids on human skin cancer cells and primary breast tumors, finding that inactivating an enzyme critical to the formation of ether lipids substantially reduced the aggressiveness of the cancer cells. Berkeley — Knocking out a single enzyme dramatically cripples the ability of aggressive […]

New Theory Shows How ‘Zombie Vortices’ Play a Role in Star Formation

August 21, 2013

0 Comments

A new theory from researchers at UC Berkeley explains how “zombie vortices” help lead to the birth of a new star. Reporting in the journal Physical Review Letters, a team led by computational physicist Philip Marcus shows how variations in gas density lead to instability, which then generates the whirlpool-like vortices needed for stars to […]

UC Berkeley Study Links Sleep Deprivation to Junk Food Cravings

August 9, 2013

0 Comments

A UC Berkeley has linked sleep deprivation to junk food cravings, finding that high-level brain regions required for complex judgments and decisions become blunted by a lack of sleep, while more primal brain structures that control motivation and desire are amplified. Berkeley — A sleepless night makes us more likely to reach for doughnuts or […]

Warmer Weather and Precipitation Increase the Risk of Violence

August 5, 2013

2 Comments

A newly published study from Princeton University and UC Berkeley reveals that slight increases in temperature and precipitation result in increased human conflict. Should climate change trigger the upsurge in heat and rainfall that scientists predict, people may face a threat just as perilous and volatile as extreme weather — each other. Researchers from Princeton […]

Scientists Grow Inexpensive High-End Photovoltaic Compounds

July 25, 2013

0 Comments

In an effort to bring high-end photovoltaics to the masses, UC Berkeley scientists have developed an inexpensive way to grow indium phosphide, a III-V compound that is used in top of the line photovoltaics. Engineers at the University of California, Berkeley, have developed an inexpensive new way to grow thin films of a material prized […]

Researchers Find a Link between Poor Sleep, Memory Loss and Brain Deterioration

January 28, 2013

1 Comment

New research from UC Berkeley suggests that sleep disruption in the elderly, mediated by structural brain changes, represents a contributing factor to age-related cognitive decline. Berkeley — The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive. But for the first time, scientists at the University of California, […]

Pressure Can Revert and Stop the Growth of Cancer Cells

December 20, 2012

0 Comments

New research showed that applying physical pressure to malignant breast cancer cells guided them back to a normal growth pattern. This research could lead to new treatments. Berkeley — Researchers at the UC Berkeley and the Lawrence Berkeley National Laboratory have put the squeeze — literally — on malignant mammary cells to guide them back […]

evidence of impending tipping point for Earth

A new paper by 22 international scientists describes the need for better predictive models based on detailed understandings of how the biosphere reacted in the past to conditions like climate change and human population growth to help future scientists better decipher how the biosphere will change as the result of the continued expansion of human […]
