Colonies of ants are incredibly complex, and at the same time intensely cooperative, so much so that they are often referred to as single 'superorganisms'. But to what extent do they actually behave as a single entity?

In order to answer this question, researchers from the University of Bristol subjected colonies of migrating ants to differing forms of simulated predator attack.

The newly described Probrachylophosaurus bergei, a member of the Brachylophosaurini clade of dinosaurs, has a small flat triangular bony crest extending over the skull and may represent the transition between a non-crested ancestor, such as Acristavus, and the larger crests of adult Brachylophosaurus, according to a study published November 11, 2015 in the open-access journal PLOS ONE by Elizabeth Freedman Fowler and John Horner from Montana State University, USA.

Ants may respond to disturbances in their nest as one highly organized 'superorganism', according to a study published November 11, 2015 in the open-access journal PLOS ONE by Thomas O'Shea-Wheller from the University of Bristol, England, and colleagues.

Many patients with serious diseases are not helped by their medications because treatment is started too late. An international research team led from Linköping University is launching a unique strategy for discovering a disease progression in its earliest phase.

The study, to be published in Science Translational Medicine, has been led by Professor Mikael Benson and Dr Mika Gustafsson at the Centre for Individualized Medication (CIMed).

Scientists have developed a highly sensitive blood test that can spot when breast cancers become resistant to standard hormone treatment, and have demonstrated that this test could guide further treatment.

The test gives an early warning of resistance to aromatase inhibitors, which are used to treat women with oestrogen receptor (ER)-positive breast cancer, the most common kind.

CINCINNATI--New research from an investigative team at the University of Cincinnati (UC) has identified biomarkers and potential therapeutic approaches that may hold the key to treating pulmonary alveolar microlithiasis (PAM), a rare lung disease.

Scar-free facial reconstruction is now a reality. A team led by Daniel Borsuk, a doctor at Hôpital Maisonneuve-Rosemont and a professor at the University of Montreal, recently conducted the very first such procedure in the history of plastic surgery in Canada. The hospital is part of the CIUSS de l'Est-de-l'île-de-Montréal health network. In an eight-hour operation on an adult patient, Dr.

The way to increase the power and efficiency of magnetic fusion energy may be to risk running the plasma - hotter than 100-million-degrees C - closer than ever to the wall, according to new experimental results achieved by the first U.S.-China fusion research team.

ITHACA, N.Y. - Good news for consumers with a sweet tooth. Cornell food scientists have reduced the sweetener stevia's bitter aftertaste by physical - rather than chemical - means, as noted in the Volume 197, Part A issue of the journal Food Chemistry.

The incidence of cancer increases with age. Conventional wisdom blames this on age-dependent accumulation of cancer-causing mutations.

WASHINGTON, Nov. 11, 2015 -- A chemistry demonstration commonly known as the "rainbow flame" experiment has resulted in a number of serious injuries in classrooms in recent years. The experiment is meant to show how various metal salt solutions can create flames of different colors, but it can be unsafe if teachers use highly flammable solvents like methanol or ethanol in the procedure. To prevent future injuries, the American Chemical Society (ACS) Committee on Safety recommends that rainbow flame experiments involving flammable solvents be discontinued immediately.

Many neurological disorders, such as Parkinson's disease and Alzheimer's disease, are marked by impaired motor skills. In addition, growing evidence suggests there's a link between some neurodegenerative diseases and body weight. A recent NIH study, for example, found that adults who are obese or overweight at midlife may be at risk for earlier onset of Alzheimer's disease.

Dust is everywhere: under the bed, on the stairs and even inside of plasmas. A team of researchers from Auburn University, the University of Iowa and the University of California, San Diego, using the new Magnetized Dusty Plasma Experiment (MDPX), the first U.S. experiment of its kind, recently discovered a new form of crystalline-like matter in strongly magnetized dusty plasma.

The sensitivity of marine communities to ocean warming rather than rising ocean temperatures will have strong short-term impacts on biodiversity changes associated with global warming, according to new research.

Pediatric oncology researchers have pinpointed a crucial change in a single DNA base that both predisposes children to an aggressive form of the childhood cancer neuroblastoma and makes the disease progress once tumors form.
