A robotic gripping arm that uses engineered bacteria to 'taste' for a specific chemical has been developed by engineers at UC Davis and Carnegie Mellon University. The gripper is a proof-of-concept for biologically-based soft robotics.
In a study with mice, a gene therapy developed in Brazil kills cancer cells and avoids adverse side effects when combined with chemotherapy.
Researchers at Karolinska Institutet in Sweden have studied which genes are expressed in overactive immune cells in mice with asthma-like inflammation of the airways. Their results, which are published in the journal Immunity, suggest that the synthesis and breakdown of fats plays an important part in the process.
Researchers suggest a possible cell-based therapy to stimulate lung development in fragile premature infants who suffer from a rare condition called Bronchopulmonary Dysplasia (BPD), which in the most severe cases can lead to lifelong breathing problems and even death. Scientists report in the American Journal of Respiratory and Critical Care Medicine they studied genetic signatures in donated human neonatal lungs by using single-cell RNA sequencing analysis and mouse models of BPD.
MIT researchers have come up with a novel way to prevent fibrosis, which can lead to rejection of implantable medical devices, by incorporating a crystallized immunosuppressant drug into the devices. After implantation, the drug is slowly and locally secreted to dampen the immune response in the area immediately surrounding the device for a period of years.
Animals learn the hard way which sights, sounds, and smells are relevant to survival. New research in flies shows that the timing of these cues plays an important role in how mental associations arise, and elucidates brain pathways involved in this process.
US hospitals wait over a year on average to begin prescribing newly developed antibiotics, a delay that might threaten the supply or discourage future development of needed drugs, according to a University of Wisconsin-Madison study.
Former war refugee Benedictus Freeman is lead author of a new paper in the peer-reviewed journal Avian Research that projects the geographic distribution of the bird through 2050.
How did humans get to be so much fatter than our closest primate relatives, despite sharing 99% of the same DNA? A new study suggests that part of the answer may have to do with an ancient molecular shift in how DNA is packaged inside fat cells, which curbed our body's ability to turn 'bad' white fat into 'good' brown fat.
Archaeologists working in two Italian caves have discovered some of the earliest known examples of ancient humans using an adhesive on their stone tools -- an important technological advance called 'hafting.'
