Dr. Arnaud Martin have found a "painting gene" that influences the pattern and evolution of butterfly wings

Scientists Find ‘Painting Gene’ Influences Pattern, Evolution of Butterfly Wings

September 18, 2017

An international team of scientists including Arnaud Martin, assistant professor of biology, made a breakthrough in understanding how genetics and evolution work in concert to shape biodiversity by investigating the complex color patterns of butterfly wings. Martin used CRISPR gene-editing technology to study the role of the WntA gene in the formation of shapes and colors on butterfly wings—and how they diversify.

Early Drafts of a Classic Work of Islamic Thought Discovered

June 08, 2017

GW Assistant Professor of History Joel Blecher recently discovered the new manuscripts of two previously unknown versions of “Fath al-Bari,” a classic work that shaped the way Sunni Muslims understand Muhammad’s sayings and practices. Dr. Blecher visited the Suleymaniye Library in Istanbul in 2014 to examine a database of digitized manuscripts that can only be accessed in person, with the goal of learning more about how medieval Muslims interpreted Muhammad’s sayings and practices, called hadith. The manuscripts reveal how medieval Islamic scholars drafted and revised their understanding of Muhammad’s teachings to the early Muslim community.

GW Establishes New Program to Bring More STEM Teachers to High-Need Schools

May 15, 2017

Research Professor of Physics Larry Medsker announced a new STEM initiative called GWNoyce. Named after the Robert Noyce Teacher Scholarship Program, this initiative offers science, technology, engineering and mathematics majors the opportunity to receive teacher training and scholarships for agreeing to teach in high-need school districts across the country after graduating from GW.

New Tool for Measuring Police and Law Enforcement Interactions Reflects Police-Based Discrimination Experiences of Black Men

May 03, 2017

Researchers led by Lisa Bowleg, Professor of Applied Social Psychology at the George Washington University, have developed a new tool to catalog police and law enforcement interactions with black men, the Police and Law Enforcement (PLE) Scale, with the hope of documenting people’s experiences and perceptions of police-based discrimination. The study found that police-based discrimination is associated with depression symptoms such as sadness, hopelessness and loss of interest and ambition. Because of this, the authors believe that police-based discrimination should be considered a public health threat.

Study Finds Bonobos May Be Better Representation of the Last Common Ancestor with Humans than Common Chimpanzees

April 28, 2017

A new study by Bernard Wood, Professor of Human Origins at the GW Center for the Advanced Study of Human Paleobiology, has provided firsthand evidence that bonobos may be more closely linked, anatomically, to human ancestors than common chimpanzees. Previous research suggested this theory at the molecular level, but this is the first study to compare in detail the anatomy of the three species.

Study Finds Medical Providers Who Prescribe PrEP to Prevent HIV Don’t See Most Patients Increasing Risky Sexual Behavior

April 26, 2017

A new study led by Assistant Professor of Clinical Psychology Sarah Calabrese found that medical providers who prescribe PrEP, which stands for pre-exposure prophylaxis and is essential to to curbing the number of new HIV diagnoses, do not see widespread increases in risky sexual behavior among their patients as a result. As such, providers do not consider such behavior change to be a reason to discontinue or limit PrEP.

Researchers Design Facial Recognition System as a Less Invasive Approach to Tracking Lemurs in the Wild

February 17, 2017

A team of researchers led by Rachel Jacobs, a biological anthropologist at GW’s Center for the Advanced Study of Human Paleobiology, has developed a computer-assisted recognition system that can identify individual lemurs in the wild by their facial characteristics. The facial recognition method has the potential to redefine how researchers track species while aiding in conservation efforts for the world’s most endangered mammals.

Human Brain and Tooth

New study finds evolution of brain and tooth size were not linked in humans

January 02, 2017

A new study co-authored by Aida Gómez-Robles, Postdoctoral Scientist and Bernard Wood, Professor of Human Origins at the University's Center for the Advanced Study of Human Paleobiology (CASHP) found that whereas brain size evolved at different rates for different species, especially during the evolution of Homo, the genus that includes humans, chewing teeth tended to evolve at more similar rates.

Limusaurus Inextricabilis

No Teeth? No Problem. Dinosaur Species Had Teeth as Babies, Lost Them as They Grew

December 22, 2016

A study co-authored by James Clark, the Ronald Weintraub Professor of Biology, has discovered that a species of dinosaur, Limusaurus inextricabilis, lost its teeth in adolescence and did not grow another set as adults. The finding, published today in Current Biology, is a radical change in anatomy during a lifespan and may help to explain why birds have beaks but no teeth.

Americans’ Likeliness to Believe in Climate Change Connected to Geographic Location and Local Weather Events

Americans’ Likeliness to Believe in Climate Change Connected to Geographic Location and Local Weather Events, Study Finds

December 19, 2016

A new study, co-authored by Associate Professor of Geography Michael Mann, found local weather may play an important role in Americans’ belief in climate change. The study revealed that Americans’ belief that the earth is warming is related to the frequency of weather-related events they experience, suggesting that local changes in their climate influence their acceptance of this worldwide phenomenon.

Male chimpanzee study reveals new insights

New Study: Male Chimpanzees Can Be Players And Good Fathers

November 08, 2016

Assistant Professor of Anthropology Carson M. Murray and postdoctoral scientist Margaret A. Stanton coauthored a paper titled, "Chimpanzee Fathers Bias Their Behavior Toward Their Offspring." The research suggests that male chimpanzees are more invested in protecting their own offspring than previously thought.

Char Beales, BA ’73, and her husband Howard Beales have pledged a $3.2 million gift to the School of Media and Public Affairs. In recognition of the changing landscape of journalism, the funding will create the Char Beales Endowed Professorship of Accountability in Journalism, focused on the importance of accuracy and accountability in journalism.

6,200-year-old textile dyed indigo-blue from Huaca, Peru

Columbian College Researcher Identifies Oldest Textile Dyed Indigo

September 14, 2016

If it weren’t for textile dying advancements made 6,200 years ago, people today might not be wearing blue jeans as a wardrobe staple. Associate Research Professor of Anthropology Jeffrey Splitstoser has identified a 6,200-year-old textile dyed indigo-blue from Huaca, Peru, a piece of dyed cotton produced more than 1,800 years before the previously known oldest textile in that color.

Preparing to Interview for Your Dream Job? Better Go in Person

July 25, 2016

Doctoral candidates Nikki Blacksmith and Jon Willford co-authored a new study examining the effects of technology-mediated interviews with Tara Behrend, associate professor of organizational sciences and communication. Through examinations of 12 articles published from 2000 - 2007 that included interviewer and interviewee ratings, they found in-person interviews yielded better impressions for the company and the candidate.

It’s Not Just Climate Change: Study Finds Human Activity Is a Major Factor Driving Wildfires

April 28, 2016

A new study examining wildfires in California found that human activity explains as much about their frequency and location as climate influences. The researchers systematically looked at human behaviors and climate change together, which is unique and rarely attempted on an area of land this large. Assistant Professor of Geography Michael Mann was lead author of the study.
