Acne treatment including the highly effective acne medication isotretinoin should be made more readily available despite reports of its association with depression and teen suicide. That's the implication of a study just published in the Journal of the American Academy of Dermatology.

Isotretinoin has been linked to depression and suicide. But UCR researcher Misaki Natsuaki, one of the study's authors, said severe acne itself, when left untreated, poses a serious risk for depression and anxiety.

Some 500 million years ago - when our continents were connected in a single land mass and most life existed underwater - hornworts (Anthoceros) were one of the first groups of plants to colonize land. An international team led by University of Zurich (UZH) and the Boyce Thompson Institute has now sequenced three hornwort genomes, providing insights into the genetics underlying the unique biology of the group, an extant representative of the earliest land plants.

DNA only persists through replication - naturally or synthetically. While humans need the genetic material to be reproduced in order to replace old or damaged cells, the ability to replicate DNA in a laboratory setting can provide researchers insights into the mechanisms of disease or the platform to develop treatments.  

Abdominal arterial (or aortic) aneurysm in older men is associated with levels of certain subtypes of white blood cells, a study from the University of Gothenburg, Sweden, shows. The study results belong to an expanding research field that is expected improve both knowledge of the disease and treatment options.

Silkworms are useful for more than just making strong and absorbent strings of silky thread for the textiles industry. A group of KAUST scientists has now coaxed these grub-like insects into making the human form of E-selectin, a critical adhesion molecule involved in inflammation, cancer and other disease processes.

A team of researchers from the Center for Soft and Living Matter, within the Institute of Basic Science (IBS, South Korea) and affiliated with Ulsan National Institute of Science and Technology (UNIST) has discovered a novel approach to selectively target and kill several types of cancer cells.

Measures against overfishing tend to protect young, immature fish through measures such as minimum-landing sizes. However, a team of researchers led by Professor Robert Arlinghaus from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Humboldt-Universität zu Berlin recommends also keeping the particularly large megaspawners alive in addition to the youngsters. This type of management achieves good compromises between the demands of commercial and recreational fisheries and the desire to conserve the reproductive capacity of fish populations.

The relief "Adoration of the Shepherds" by the Italian sculptor Giuseppe Torretti is disfigured by lumpy salt crystals. Now, a research group at the Max Planck Institute for Solid State Research in Stuttgart has established that the calcium acetate hemihydrate that makes up these efflorescences bears a similar structure to the protein collagen. The structural characteristics not only help prevent damage of this kind, but have also provided the researchers with interesting new ideas for bioinorganic chemistry.

CHAMPAIGN, Ill. -- Two brain-signaling molecules control how anemonefish dads care for their young and respond to nest intruders, researchers report in a new study. Because there are many similarities in brain structure between fish and humans, the findings offer insight into the fundamental nature of parental care, the scientists say.

NASA's Aqua satellite passed over the Southern Indian Ocean and captured an image of a well-developed Tropical Cyclone Herold at hurricane strength, east of Madagascar.

Herold formed on March 13 as Tropical Cyclone 22S and once it intensified into a tropical storm, it was renamed Herold. Herold continued to strengthen and is now at hurricane-force.
