In "Group Discussion Improves Lie Detection," the researchers designed four experiments in which groups consistently distinguished truth from lies more accurately than one individual, demonstrating that the group advantage in lie detection comes through the process of group discussion, not the product of a "wisdom of crowds" effect.
Scientists at Georgia State University (GSU) with funding from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have designed an imaging technique to detect early-stage liver tumors, and have proven it successful in mice. Their study in an animal model is an essential step toward creating tools to improve liver tumor detection in human patients—whether primary liver cancer or metastatic tumors that arise in liver but have spread from other tissue.

In a new study published June 8 in the Proceedings of the National Academy of Sciences, David C. Schwartz and his University of Wisconsin-Madison research team describe a new approach for studying the cancer genome that Schwartz says will let scientists account for both the individual tiles and the whole mosaic. It enables researchers and clinicians to look at the small- and large-scale genetic changes that define individual cancers.
Countering previously held beliefs, researchers at The University of Texas MD Anderson Cancer Center have discovered that inhibiting the immune receptor protein TLR4 may not be a wise treatment strategy in all cancers.
A study of the rapid evolution of the insulin-signaling molecular network that regulates growth, reproduction, metabolism and aging lays important groundwork for future studies.

A new Iowa State University study focusing on insulin signaling uncovered surprising genetic diversity across reptiles, birds and mammals. Scientists previously assumed the process remained much the same throughout the animal kingdom, but the new research shows that the genetic pathways in reptiles evolved to include protein forms not observed in mammals.

MicroRNA can serve as a “decoder ring” for understanding complex biological processes, a team of New York University chemists has found. Their study points to a new method for decrypting the biological functions of enzymes and identifying those that drive diseases.
Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins University and the University of Maryland say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.
Researchers at University of California, San Diego School of Medicine and Moores Cancer Center have now identified six mRNA isoforms (bits of genetic material) produced by ovarian cancer cells but not normal cells, opening up the possibility that they could be used to diagnose early-stage ovarian cancer. What’s more, several of the mRNA isoforms code for unique proteins that could be targeted with new therapeutics.
Emplacement of carbon dioxide at the Bravo Dome gas field in New Mexico began more than 900,000 years earlier than previously estimated, according to scientists at DOE’s Center for Frontiers of Subsurface Energy Security. The study documents the first field evidence for the safe long-term storage of large amounts of carbon dioxide in saline aquifers.
Researchers created thin, flexible electronic devices that efficiently harvest the mechanical energy from natural motions of the human body. In addition to advances in materials processing to enable creating these devices, accurate analytical models were developed to predict the electrical output.
Nearly 70,000 people worldwide are living with cystic fibrosis, a life-threatening genetic disease. There currently is no cure for the condition, but researchers from the University of Missouri have identified a key component in the protein that causes the disease. It is a finding that may lay the foundation for the development of new medications and improved therapies.
Modern lifestyles have made our bones lighter weight than our hunter-gatherer ancestors. A study of the bones of hundreds of humans who lived during the past 33,000 years in Europe finds the rise of agriculture and a corresponding fall in mobility drove the change, rather than urbanization, nutrition or other factors.

An important link between the human body clock and the immune system has relevance for better understanding inflammatory and infectious diseases, discovered collaborators. They report how a critical white blood cell, when exposed to bacteria, makes the biological clock inside the macrophage stop, allowing it to become inflamed.
Led by Georgia State University, researchers have developed the first robust and noninvasive detection of early stage liver cancer and liver metastases, in addition to other liver diseases, such as cirrhosis and liver fibrosis.
Scientists at The University of Manchester have made an important discovery about how certain cells stick to each other to form tissue.
