Research by Marc Breedlove suggests that higher levels of male hormones in the womb can increase a person's likelihood of developing a homosexual orientation. Finger length measurements, influenced by fetal androgen levels, also showed correlations with sexual orientation.
Researchers have discovered a way to harness nature's own tool, photosynthesis, to produce hydrogen gas from sunlight and water, offering a promising alternative fuel source.
The boom in global trade poses a significant threat to the US ecosystem, resulting in $136 billion in annual losses from invasive species. Invasive insects, plant pathogens, and weeds are entering the country through nursery stock, cargo containers, and imports, causing widespread damage to crops, forests, and native wildlife.
Researchers used a scanning tunneling microscope to visualize the electron clouds around impurities in copper oxide superconductors, shedding light on their behavior and potential applications. The study provides new insights into the mechanism of high-critical-temperature superconductivity.
Scientists propose a revised four-point location model to explain how proteins discriminate between mirror-image molecules. This new understanding could significantly impact drug design, as it challenges the long-held three-point attachment model and may lead to more effective treatment strategies.
Researchers at UC Berkeley and UC San Francisco have developed a diagnostic technique that measures T-cell production rates in patients with AIDS. The study found that potent protease inhibitor treatments can increase T-cell production, suggesting new treatment options for patients.
A team of experts from UC Berkeley's engineering school have developed a machine to zap static cling, allowing fragile ancient papyrus documents to survive. The recovery includes royal proclamations, land transactions, and literary texts from the third century B.C., dating back thousands of years.
The discovery of EUV emissions in the Coma cluster suggests a large cloud of cooler matter, totaling up to 10 trillion of our Suns, which could help clear up a major problem with these galactic groupings. The findings also hint at the presence of normal baryonic matter instead of dark matter or exotic particles.
Researchers from UC Berkeley have disproved the hypothesis that the Earth's inner core is a perfectly aligned mass of iron crystals. Instead, they found that the crystals align themselves like boats in a circular eddy, driven by the rise of hotter iron toward the surface. This finding has implications for modeling the Earth's magnetic ...
Scientists have documented the invasion of a single-celled amoeba-like organism, Trochammina hadai, into San Francisco Bay, raising concerns about the impact on native species and ecosystem. The introduction of exotic microorganisms is a growing problem in US waters, with potential consequences for harbors and waterways.
A comprehensive analysis of California hospital records reveals a historic transformation in the role of hospitals. Hospital inpatient care has declined significantly, with outpatient surgeries more than doubling during the same period.
UC Berkeley's Center for Extreme Ultraviolet Astrophysics will take over day-to-day operations of the Extreme Ultraviolet Explorer (EUVE) observatory, fostering space science and technology innovation. The transfer aims to reduce costs and increase educational outreach through project-based learning experiences.
Scientists at UC Berkeley developed a 3D model that explains the size and shape of tectonic plates, predicting they are larger than previously thought due to increased mantle viscosity. The model simulates convection cells in the mantle, resulting in large plates and subduction zones.
Researchers estimate Tyrannosaurus Rex could exert a biting force of up to 3,011 pounds on its prey, with 58 definite T-rex bite marks found on a Triceratops pelvis. The powerful dinosaur's teeth were as strong as those of an alligator, suggesting it could have struggled with its prey.
