Researchers discovered new clues to biological clocks that pace daily activities, including the role of two proteins regulating light responses. Their findings link evolutionary spectrum from light perception to time keeping, paving way for detailing modern clock mechanisms in various organisms.
High blood pressure can lead to enlargement of heart cells and a silent defect in the heart's pumping mechanism. The researchers found that this defect reduces contraction in each heart cell, contributing to heart failure. Developing novel treatments may be possible with improved understanding of the molecular defects.
A new approach called PIWI (Parents Interacting With Infants) suggests that parents should follow a child's lead during playtime to aid development. This method involves seeing through the child's eyes and adapting interventions accordingly, rather than imposing adult agendas.
Researchers at University at Buffalo successfully demonstrate collective flow of nucleons resulting from stopping high-energy lead beam, a critical prerequisite for producing quark/gluon plasma. The achievement confirms theoretical predictions and brings optimism to the field of quark/gluon plasma detection.
Researchers suggest restoring natural wetlands in floodplains as a solution to address flooding problems. The strategy is based on lessons learned from the 1993 Upper Mississippi River floods and has cultural and economic implications for landowners and communities along the Illinois River.
A new study suggests that an adaptive-decision strategy can reduce costs and damages associated with climate change. By observing the climate system and making mid-course corrections, policymakers can make more reasonable and defensible choices about climate-change policy.
A new chemical methodology developed by a chemist at the University of Illinois has made synthesizing both enantiomers of alpha-, beta- and gamma- aryl amino acids more efficient. The production of unnatural amino acids is of particular interest to the pharmaceutical industry, where it can enhance the stability of possible drugs.
