The species that historically was quoted as the most abundant of coral algae that forms rodoliths at the Gulf of California in Mexico, is in reality a compound of five different species. This finding was made by a marine biologist, resulting in a change of paradigm in the study of the species known as Lithophyllum margaritae....

Researchers found that the most common emotions trigger strong bodily sensations, and the bodily maps of these sensations were topographically different for different emotions. The sensation patterns were, however, consistent across different West European and East Asian cultures, highlighting that...

Researchers Aalto University have revealed how emotions are experienced in the body. Emotions adjust our mental and also bodily states to cope with the challenges detected in the environment. These sensations arising from the bodily changes are an important feature of our emotional experiences. For...

These results indicate that the fetal umbilical vein has appropriate stress relaxation and creep properties for transplantation. These properties are advantageous for vascular reconstruction, indicating that the fetal umbilical vein can be transplanted to repair middle cerebral artery injury....

Dr. Chengdong Piao and colleagues from Second Hospital, Jilin University in China prepared sciatic nerve injury models by creating a 10 mm defect in sciatic nerve specimens harvested from fresh corpses, and defects were repaired by anastomosis with nerve autografts and poly(lactic-co-glycolic acid)...

Lens antennas are in widespread use in a variety of applications. Recently, an accurate method was proposed to design large-aperture, three-dimensional gradient-index (GRIN) slab lens antennas. Compared with traditional dielectric lenses of the same aperture, the proposed antennas promise superior...

In deserts, variable weather is common so that plant community patterns can change between wet and dry years, with high densities and a diversity of plants in wet years, and a reduction in both quantity and number of species in dry years. The effect that two important variables have on plant...

A study based on the reflections of third-year Loyola University Chicago Stritch School of Medicine students is shedding light on the struggle physicians in training often face when trying to control their own emotions while not becoming desensitized to the needs of the dying patient and his or her...

A short fragment of chloroplastic DNA as a "barcode" for species identification within a group of palm species, including the economically important date palm Phoenix dactylifera, has been proposed by researchers from IRD, France, and CRA-FSO, Italy. Species and hybrids recognition is important for the protection of endemic or...

The ability to sequence the DNA of plants and animals has revolutionized many areas of biology, but the unstable character of DNA poses difficulties for sequencing specimens in museum collection over time. In an attempt to answer these issues, a recent study of 31 target spider species discovers that both time and body size are...

An Iranian ornithologist used a "ready for use" museum collection to DNA barcode 147 bird species from The Netherlands. While fast and accurate identifications could be confirmed for most species, gulls and skuas showed fuzzy boundaries and, in contrast, Lesser Whitethroats diversified in more than one species.
