New research -- the evolution of complementary cognition -- proposes that in adapting to enormous environmental upheavals over hundreds of thousands of years, humans evolved to specialize in different but complementary forms of cognition, styles of 'thinking,' that work together as a complex adaptive system -- a kind of collective brain.

Killer whales have complex social structures including close "friendships", according to a new study that used drones to film the animals.

A junk food diet may increase the risk of dangerous driving among truck/lorry drivers by boosting fatigue, which is often a key factor in vehicle collisions, suggests research published online in the journal Occupational & Environmental Medicine.

Strict rest after a sports related concussion slows recovery and may prolong symptoms, says a consensus statement drawn up by a US expert panel on how best to treat and manage the condition, and published in the British Journal of Sports Medicine.

A new positron emission tomography (PET) radiotracer can detect abdominal aortic aneurysms (AAAs) and potentially predict when they will rupture, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting. Targeting a novel biomarker associated with AAA, the radiotracer is effective both in diagnosis and in providing information to assist in the development of AAA treatments, of which there currently are none.

In a new study, North Carolina State University researchers demonstrated they could print layers of electrically conductive ink on polyester fabric to make an e-textile that could be used in the design of future wearable devices.

A new study shows political partisans may engage in greater victim blaming for sexual assault crimes, especially when the members of their political party are accused. The more Republicans and Democrats identified with belonging to their political party and reported feeling defensive when members from their political party are criticized, the more accepting they were of common sexual assault myths and the less likely to perceive sexual assault as a serious issue.

As threats against female journalists rise, a researcher examines the damage done by the Hollywood trope of the unethical female reporter who trades sex for information.

New research from UC Davis suggests that remembering a song in your head is more than a passing nuisance -- it plays an important role in helping memories form, not only for the song, but also related life events.

An underwater archaeologist from The University of Texas at Arlington is part of a research team studying 9,000-year-old stone tool artifacts discovered in Lake Huron that originated from an obsidian quarry more than 2,000 miles away in central Oregon. The obsidian flakes from the underwater archaeological site represent the oldest and farthest east confirmed specimens of western obsidian ever found in the continental United States.

For the first time, researchers have used precariously-balanced rocks to set the formal design earthquake motions for a major existing engineered structure--the Clyde Dam, the largest concrete dam in New Zealand.

Evaluation of three COVID-19 vaccine candidates in 2020-21 during a worldwide pandemic was unprecedented in terms of urgency and scope. Responsibility for the safety, integrity and scientific validity of U.S. trials fell to 12 experts of the federally appointed COVID-19 Vaccine Data and Safety Monitoring Board, who in turn report to an oversight group. This team has now taken the unusual step of publishing details of their review process in The Journal of Infectious Diseases.

Instead of looking at the reasons child welfare caseworkers leave their jobs, Oregon State University researchers examined the common factors among workers who stay in the field, and what makes them feel most satisfied in their work.

A group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate elicited durable neutralizing antibody responses to SARS-CoV-2 in pre-clinical research. There were no adverse effects.

Dr. Igor Ivanishin, a postdoctoral researcher in the Harold Vance Department of Petroleum Engineering at Texas A&M University, has firsthand experience with the frustrations of oil production. He spent nine years as a hydraulic fracturing engineer with operating and service companies in Russia. A few years ago, he came to Texas A&M to get his doctoral degree while delving into a reoccurring recovery problem in carbonate reservoirs: why don't they produce oil as predicted?

A new article analyzes Chile's transition in 1990 from dictatorship to democracy, the nature of democracy between 1990 and 2019, and the appearance of several social movements geared to expanding this democracy.

Researchers reporting in Advanced Photonics demonstrate the conversion of infrared images to the visible, using ultrathin and transparent semiconductor nanocrystals.

Freiburg researchers find new mechanism for classical behavior of many-particle quantum systems.

A phase III clinical trial has validated the effectiveness of the prostate-specific membrane antigen (PSMA)-targeted radiotracer 18F-DCFPyL in detecting and localizing recurrent prostate cancer. Approved by the FDA last month, the radiotracer identified metastatic lesions with high positive predictive values regardless of anatomic region, adding to the evidence that PSMA-targeted radiotracers are the most sensitive and accurate agents for imaging prostate cancer. This study was presented at the SNMMI 2021 Annual Meeting.

In 1943, two scientists named Max Delbrück and Salvador Luria conducted an experiment to show that bacteria can mutate randomly, independent of external stimulus, such as an antibiotic that threatens a bacterial cells' survival. Today the Luria-Delbrück experiment is widely used in laboratories for a different purpose--scientists use this classic experiment to determine microbial mutation rates.
