A new study highlights the importance of managing multiple species to prevent extinction, according to Dr. Ron Pulliam, director of the National Biological Service. By identifying vulnerable species and human activities threatening them, conservation efforts can be targeted to save species.
A proposed dam in northern Thailand could submerge a golden teak forest, devastating wildlife and biodiversity. The project aims to account for the ecological, social, and cultural implications of such projects.
A paper by Peter D. Usher presents evidence that Shakespeare's Hamlet is an allegory for the competition between cosmological models of Thomas Digges and Tycho Brahe. The play dramatizes the struggle to discover the real picture of the universe from appearances in the sky. Hamlet favors the Diggesian model, which is the forerunner of m...
David Van Essen suggests that mechanical tension from axon connections creates brain folds. His hypothesis explains why human cortex is convoluted while others are smooth, and supports observations from transgenic mice studies. The theory could also account for individual differences in brain shapes.
Researchers have identified key chemokine receptors that enable HIV to infect immune system cells, including CCR5 and CCR-3. Understanding these interactions could lead to the development of new treatments and prevention strategies for HIV/AIDS.
Researchers developed a model to explain the Earth's inner core rotating faster than the rest of the planet, driven by electromagnetic forces and outer core fluid motions. The model provides insights into the mysterious processes generating the magnetic field deep within the Earth's core.
Participants of a forest-biodiversity workshop suggest using logging as a tool to save tropical forests and their wildlife. By implementing basic techniques such as directional felling and minimizing logging roads, biodiversity can be conserved. The experts also emphasize the need to maintain suitable habitat within major forest types.
Cornell researchers have developed a new technique to measure serotonin concentration in live cells, using pulsed lasers for excitation. This method allows for the visualization of serotonin secretory granules in real-time without damaging the cell or requiring external fluorescent markers.
The UNESCO Director-General urges scientists to take a more active role in shaping public policy, citing their ability to influence decision-makers. Scientists will have diverse opinions on the possible agenda for a World Science Conference.
A 22-year study found that socially dominant men, characterized by monopolizing conversations and excessive competitiveness, had a 60% higher rate of all-cause mortality compared to less dominant individuals. This suggests that social dominance is a moderate risk factor for early death.
