A survey of 166 nearby stars like our sun reveals increasing numbers of smaller planets down to the smallest detectable planets - about three times more massive than the earth. If this trend continues, UC Berkeley astronomers estimate, one of every four sun-like stars may have an earth-like planet.
Two of the five probes in the THEMIS mission have been redirected toward new orbits around the moon, extending UC Berkeley's study of the earth and moon's interaction with the solar wind. The new mission, dubbed ARTEMIS, began science operations Oct. 21 when the second of the two probes entered a parking orbit on the Earth-facing side of the moon.
A team of scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory has detected six isotopes, never seen before. Information gained from the new isotopes will contribute to a better understanding of the theory of nuclear shell structure, which underlies predictions of an “Island of Stability,” a group of long-lasting isotopes thought to exist amidst a sea of much shorter-lived, intrinsically unstable isotopes of the superheavy elements.
Researchers advocate teacher training, mentoring to boost preschool results The report, Lifting Pre-K Quality: Caring and Effective Teachers," says governors and federal leaders should rely less on regulations and more on improving teacher quality to combat the often disappointing benefits of preschool.
Jeanna Burrell, an assistant professor at Berkeley's School of Information, has been awarded a National Science Foundation grant to study the use of digital tools by marginalized populations in four countries.
Delays from domestic flights put a $32.9 million dent into the U.S. economy, and half that cost is borne by airline passengers, according to a new report led by UC Berkeley researchers. The final report was delivered Oct. 18 to the Federal Aviation Administration, which commissioned the study.
California taxpayers are not overpaying or overcompensating their state and local workers compared to private sector employers, according to a policy brief released today (Monday, Oct. 18) by the Center on Wages and Employment Dynamics at UC Berkeley’s Institute for Research on Labor and Employment.Wages earned by California’s public employees are about 7 percent lower, on average, than those received by comparable private sector workers, according to the report. However, the researchers concluded that when taking into account the more generous benefits of government employees, there is no significant difference in the level of total compensation between the two sectors.
The size of a cell's nucleus varies by species, by cell type, and with disease: many cancer cells develop larger nuclei as they become more malignant. Working with the African clawed frog, Professor Rebecca Heald and post-doc Daniel Levy have discovered two proteins that control the size of the nucleus.
If chromosomes are to separate properly during cell division, the microtubules in the cell must grab onto them and pull them apart. The place where the microtubules latch on is a large molecular complex called the kinetochore. Eva Nogales and her UC Berkeley/LBNL team have created the first high-resolution image of this junction and identified regulators that prevent errors that can lead to cancer or death.
A large-scale analysis of existing research reinforces the growing consensus that the mathematical skills of boys and girls, as well as men and women, are substantially equal. The study team, including Marcia Linn, Berkeley professor of education, reviewed 242 research articles assessing the math skills of nearly 1.3 million people.
