From the playground to the board room, people often conform to the behavior of those around them as a way of fitting in. New research shows that this behavioral conformity appears early in human children, but isn’t evidenced by apes like chimpanzees and orangutans.

By manipulating a plant’s metabolic pathways, two scientists have figured out a way to genetically rewire plants to allow for an exceptionally high level of control over the spatial pattern of gene expression, while at the same time boosting expression to very high levels. Now, they have launched a startup company to apply this technology for developing low-cost biofuels that could be cost-competitive with gasoline and corn ethanol.
New research has shown that despite moving house frequently, bats choose to roost with the same social groups of “friends.” The study found that different social groups roost in separate, though adjacent, parts of woodland. The findings have important implications for conservation as bats may not be able to move to another area if a section of woodland is felled.
A study has provided insights into where stem cells come from and could advance research in regenerative medicine. The work also has significant implications for fertility research.
Researchers have developed a way to use sound to create cellular scaffolding for tissue engineering, a unique approach that could help overcome one of regenerative medicine’s significant obstacles.
Turns out your mom was right: scratching an itch only makes it worse. New research indicates that scratching causes the brain to release serotonin, which intensifies the itch sensation. The find provides new clues that may help break that cycle, particularly in people who experience chronic itching.
Researchers have developed a suite of technologies that can be used to enhance communication between dogs and humans. It has applications in everything from search and rescue to service dogs to training our pets. The platform opens the door to new avenues for interpreting dogs’ behavioral signals and sending them clear and unambiguous cues in return.
Scientists have shown that there is a link between perinatal exposure to BPA at low doses and the risk of developing food intolerance in later life. This research, involving rats, suggests that early life exposure at a dose significantly below the current human safety limit set by the FDA affects developing immune systems, predisposing offspring to food intolerance in adulthood.
An advocacy group says it found about 30 percent of 143 shrimp products bought from 111 vendors were not what the label said. Cheap imported farm-raised shrimp is being sold as prized wild-caught Gulf shrimp, common shrimp sold as premium shrimp and shrimp of all kinds sold with no indication whatsoever about their origin.
Plants rely on sunlight to make their food, but they also need protection from its harmful rays, just like humans do. Now, scientists have discovered a group of molecules in plants that shields them from sun damage.
Mimicking natural evolution in a test tube, scientists have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth. Aside from illuminating one possible path for life's beginnings, the achievement is likely to yield a powerful tool for evolving new and useful molecules.
Scientists used pluripotent stem cells to generate functional, three-dimensional human stomach tissue in a laboratory– creating an unprecedented tool for researching the development and diseases of an organ central to several public health crises, ranging from cancer to diabetes.
Laboratory contaminants likely explain the results of a recent study claiming that complete genes can pass from foods we eat into our blood, according to a molecular biologist who reexamined data from the controversial research paper. The findings highlight an underappreciated problem— contamination of laboratory samples— with one of the most popular and powerful new tools of the discipline: high-throughput sequencing.
An extract from shiitake mushrooms appears to be effective for the eradication of human papillomavirus (HPV), according to a pilot clinical trial. Ten HPV-positive women were treated orally with the extract, AHCC, once daily for up to six months. Five achieved a negative HPV test result– three with confirmed eradication after stopping AHCC.
Researchers using a combination of different imaging techniques have found structural abnormalities in the brains of people with chronic fatigue syndrome, according to a new study. The results suggest a potential role for imaging in diagnosing and treating the condition.
For decades, honeybees have been battling a deadly disease that kills off their larvae and leads to hive collapse. It’s called American Foulbrood and its effects are so devastating and infectious, it often requires infected hives to be burned to the ground. Now, an undergraduate has produced a natural way to eliminate the scourge, and it’s working: using tiny killer bugs known as phages to protect baby bees from infection.
A high milk intake in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death, suggests observational research. This may be explained by the high levels of lactose and galactose in milk, which have been shown to increase oxidative stress and chronic inflammation in animal studies.
A population of endangered giant tortoises, which once dwindled to just over a dozen, has recovered on the Galapagos island of Española. Some 40 years after the first captive-bred tortoises were reintroduced to the island by the Galapagos National Park Service, the endemic Española giant tortoises are reproducing and restoring some of the ecological damage caused by feral goats that were brought to the island in the late 19th century.
Humans are the only primates with large, highly visible sclera– the white part of the eye. The eye plays a significant role in the expressiveness of a face, and how much sclera is shown can indicate the emotions or behavioral attitudes of a person. A new study has found that the ability to respond to eye cues apparently develops during infancy– at around seven months.
Researchers have developed a novel method to test for vitamin B12 deficiency that is sensitive enough to work on anyone, including newborn babies and large swaths of the general population.
All living cells use membranes to define physical boundaries and control the movement of biomolecules. Now, researchers have found a self-driven reaction can assemble phospholipid membranes, like those that enclose cells.
Difficulty in conceiving a child is a major challenge for one in seven heterosexual couples in America, especially for those over the age of 35. Now, a study has found that neutralizing an immune system gene could improve the success of fertility treatments in women.
Amoebas aren’t the only cells that crawl: movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies, researchers have answered long-standing questions about how complex cells sense the chemical trails that show them where to go— and the role of cells’ internal “skeleton” in responding to those cues.
A potentially lethal bacterium protects itself by causing immune tunnel vision, according to a study. By tricking the immune system into focusing on one bug-associated factor, the bacterium Staphylococcus aureus dodges the production of antibodies that would otherwise protect against infection.
Scientists combined high-resolution 3-D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with respect to three key cellular processes simultaneously: cell shape, microtubule organization and cell cycle progression.
