A team of researchers led by Bradley and Yale archaeologist Harvey Weiss found that sudden climate changes were often present in societies that collapsed during the past 10,000 years. The study suggests that climate change was a major factor in the collapse of several societies around the world.
A recent study published in the American Journal of Epidemiology found that breastfeeding for two or more years significantly reduces breast cancer risk among Chinese women. The study showed a 50 percent reduction in breast cancer risk for women who breastfed for more than 24 months, compared to those who did not.
The new mathematical method drastically speeds up the time it takes to calculate the behavior of how drops form as they come out of a nozzle or faucet. This breakthrough has broad applications in improving industrial processes such as inkjet printers, photographic films, and analytical devices.
A study by Oklahoma State University researchers found that changes in the American Great Plains have affected birds, with some species benefiting from woody habitat and others declining due to habitat loss. Management options such as prescribed fire and grazing animals may help mitigate these impacts.
Biologists from UCLA and Swedish universities have uncovered the history of how wild horses were domesticated, revealing widespread interbreeding across multiple regions. The study found that genetic diversity was much higher than previously thought, suggesting a more complex process of domestication.
A team of scientists analyzed sediment core samples from Lake Titicaca in Bolivia and Peru, revealing a 25,000-year precipitation record that suggests tropical South America was wet during the last Ice Age. The findings challenge traditional views that the region was dry during this time period.
Researchers at Virginia Tech found that stimulating a mother's immune system can increase growth factors in the fetus, reducing birth defects. The study suggests a new role for maternal immunity in fetal development, potentially unlocking secrets to reversing certain birth defects.
The $54 million Substance Abuse Policy Research Program aims to produce information on ways to reduce harm caused by tobacco, alcohol, and illicit drug use. The program has awarded over 131 grants totaling $25 million, with a focus on public and private interventions to address substance abuse.
Purdue University researchers have developed a method to sort and isolate chemical compounds as they are made, identifying the most biologically active compounds among millions of candidates. The new method combines state-of-the-art imaging technology and combinatorial chemistry, reducing screening times by four to 12 times.
Researchers at Lehigh University have successfully made droplets of water move at faster rates by utilizing surface tension gradients and fast condensation, showing potential applications in heat transfer and microfluidic devices
Researchers have identified the RMRP gene responsible for cartilage-hair hypoplasia, a rare syndrome causing dwarfism. The discovery may lead to better understanding and treatment of the disease, which affects worldwide but is prevalent in Finnish and Amish populations.
Researchers unveil a new model suggesting magnetic dynamo forces shape planetary nebulae by twisting radiating material into distinctive shapes. The discovery sheds light on the cosmic 'paintbrush' responsible for creating stunning nebulae, with implications extending beyond our solar system.
Researchers analyzed ancient coral cores to study climate patterns and found that El Niño was weaker during ice ages, while warm periods saw stronger events. The findings suggest global warming may be responsible for recent intense El Niño events, but more research is needed.
A study published in Neuron found that ephrin-B3 plays a key role in the connection between the brain and spinal cord, which is essential for forming motor connections. The research provides new insights into mirror movement disorder, a rare condition characterized by involuntary symmetrical movements of limbs.
