In contrast to a toothed whale, which retains teeth that aid in capturing prey, a living baleen whale (e.g., blue whale, fin whale, humpback, bowhead) has lost…
Organic nanostructures are key elements of nanotechnology because these building blocks can be made with tailored chemical properties. Their disadvantage has…
In the study, published in the journal PLoS Biology, Penn researchers developed a novel computational approach to infer the dynamics of species diversification…
In his new book, “Honeybee Democracy,” Thomas Seeley, professor of neurobiology and behavior, describes the elaborate decision-making process that honeybees…
Aggressive breast cancers with poor prognosis typically have abnormal levels of the protein HER2 (the tyrosine kinase human epidermal growth factor receptor…
However, it can be dangerous to patients whose immunological system has been weakened such as after organ transplants or chemotherapy with cancer. Then, this…
The Galapagos Islands, which once served as a scientific laboratory for Charles Darwin, boast a number of unique plant and animal species, from tortoises to…
Understanding the processes inside the nucleus of a cell, which houses DNA and is the site for transcribing genes, could lead to greater comprehension of…
The bendable devices are composed of water-based gel infused with light-sensitive molecules – the researchers used plant chlorophyll in one of the experiments…
UC Berkeley researchers applied transcranial magnetic stimulation (TMS) to the posterior parietal cortex region of the brain in 33 right-handed volunteers and…
Rice University physicist Dmitri Lapotko has demonstrated that plasmonic nanobubbles, generated around gold nanoparticles with a laser pulse, can detect and…
About ten years ago, the discovery of microRNAs — tiny cellular molecules that regulate our genetic code — unlocked a world of scientific possibilities,…
Our bodies daily eliminate in a controlled manner more than 100 million defective cells, by means of a procedure known as ‘cell suicide’ or apoptosis. This is…
Pedram Mohseni, a professor of electrical engineering and computer science at Case Western Reserve University, and Randolph J. Nudo, a professor of molecular…
Research published this week in Nature Nanotechnology shows a new method of enzyme-controlled movement of a single strand of DNA through a protein nanopore….
Flowering plants produce nectar to attract insect pollinators. Some plant species, such as Lima bean, also secrete nectar from so-called extrafloral nectaries…
