When male chimpanzees of the world’s largest known troop patrol the boundaries of their territory in Ngogo, Uganda, they walk silently in single file. Normally chimps are noisy creatures, but on patrol they’re hard-wired. They sniff the ground and stop to listen for sounds. Their cortisol and testosterone levels are jacked 25 percent higher than normal. Chances of contacting neighboring enemies are high: 30 percent. Ten percent of patrols result in violent fights where they hold victims down and bite, hit, kick and stomp them to death. The result? A large, safe territory rich with food, longer lives, and new females brought into the group.Read More →

Various studies illustrate that cooperative learning can help students to learn the science information you are trying to teach them. Sometimes, students have the ability to learn better and faster from their peers than directly from the teacher. Studies also show that the benefits of cooperative learning for students is more than just the ability to learn the information at hand. For one, students that do not do as well in science as some of their peers learn better when they are in cooperative learning groups with a mixed ability of students. This means that a student that doesn’t do well can learn from theRead More →

If you are have been teaching for a short time period, you may be searching for teaching techniques that can help you get across information to your science class. Even if you are a seasoned teaching, you may seeking new ways to get the same information across to a new batch of students year after year. Teaching students requires you to draw inspiration from a myriad of resources. Other Teachers One of the first places to learn what teach methods seem to work and which ones seem to bomb are from your fellow teachers. When you are in the teachers’ lounge or walking in theRead More →

Patients with dementia may actually die sooner if their family caregivers are mentally stressed, according to a new UC Berkeley study. From 2007 until 2016, UC Berkeley researchers tracked the mortality of 176 patients with neurodegenerative diseases that are corrosive to brain function. They also measured the mental health of the family members who took care of them. Their findings, published in the Proceedings of the National Academy of Sciences journal, indicate that patients tended by caregivers with depression, anxiety and other symptoms of mental illness typically died sooner than those being looked after by caregivers in good mental health. For example, compared to patients whoRead More →

When it comes to the fat in your diet, the line between good and bad just got blurrier. Liberal consumption of so-called good fats – like those found in olive oil and avocados – may lead to fatty liver disease, a risk factor for metabolic disorders like type 2 diabetes and hypertension, according to a new study by scientists at UC San Francisco. The findings, in mice, surprised even the researchers, who were expecting saturated fat – popularly known as the worse kind – to cause more fat buildup in livers. “The belief in the field for quite some time has been that saturated fatRead More →

Dialysis, in the most general sense, is the process by which molecules filter out of one solution, by diffusing through a membrane, into a more dilute solution. Outside of hemodialysis, which removes waste from blood, scientists use dialysis to purify drugs, remove residue from chemical solutions, and isolate molecules for medical diagnosis, typically by allowing the materials to pass through a porous membrane. Today’s commercial dialysis membranes separate molecules slowly, in part due to their makeup: They are relatively thick, and the pores that tunnel through such dense membranes do so in winding paths, making it difficult for target molecules to quickly pass through. NowRead More →

The Nature Publishing Group runs a social networking website for science education and research. The name of the website is Scitable. The website provides free access to a library filled with content on science topics of all sorts. In addition, the site offers tools to spur science learning and conducting research on science topics. The Scitable website turned one in January 2010. The focus on the website is a combination of life sciences, but the site also includes tools teachers can use to manage teaching lessons to students in a classroom environment. The content contributors include scientists and teachers, but the social networking also includesRead More →

Using cooperative learning as a technique to teach your students about science involves more than grouping students together and allowing them to help each other learn. It is also about mixing and mingling the abilities of the students that make up each group. Experts say that cooperative learning has seven elements that must exist to achieve success with this teaching methodology. Interdependence: The students need to have the belief that each of their actions either helps the group succeed or leads the group down the other path. In-person interaction: Group the children in rows or circles where they have to face each other while workingRead More →

Many cognitive processes, such as decision-making, take place within seconds or minutes. Neuroscientists have longed to capture neuron activity during such tasks, but that dream has remained elusive — until now. A team of MIT and Stanford University researchers has developed a way to label neurons when they become active, essentially providing a snapshot of their activity at a moment in time. This approach could offer significant new insights into neuron function by offering greater temporal precision than current cell-labeling techniques, which capture activity across time windows of hours or days. “A thought or a cognitive function usually lasts 30 seconds or a minute. That’sRead More →

Scientists, including Tina Weatherby with the University of Hawai‘i at Mānoa (UHM) School of Ocean and Earth Science and Technology (SOEST), published a study wherein they reconstructed the skin of endangered green turtles, marking the first time that skin of a non-mammal was successfully engineered in a laboratory. In turn, the scientists were able to grow a tumor-associated virus to better understand certain tumor diseases. In an international collaboration led by the U.S. Geological Survey, scientists engineered turtle skin in order to grow a virus called chelonid herpesvirus 5 or ChHV5. ChHV5 is associated with fibropapillomatosis, known as FP, a tumor disease affecting green turtles worldwideRead More →
