CNN —The Dana-Farber Cancer Institute, a prestigious Harvard teaching school, is moving to retract six studies and correct 31 others following allegations of data manipulation. The steps by the Harvard Medical School affiliate come after a molecular biologist published a blog post earlier this month alleging researchers falsified data by manipulating images. More than 50 papers are part of the ongoing review by Dana-Farber into four researchers, all of whom have faculty appointments at Harvard Medical School. Earlier this month, Sholto David published a blog post titled “Dana-Farberications at Harvard University,” alleging researchers at the cancer institute manipulated images and data. According to Rollins, Dana-Farber said it was already reviewing “potential data errors” in multiple cases that the blog listed and stressed that the issues uncovered do not necessarily amount to misconduct.

Last year doctors offered to treat Horton’s infection with one of nature’s oldest predators — tiny tripod-looking viruses called phages designed to find, attack and gobble up bacteria. SCIEPRO/Science Photo Library/Getty ImagesThe microscopic creatures have saved the lives of patients dying from superbug infections and are being used in clinical trials as a potential solution to the growing problem of antibiotic resistance. Would the bacteria from her ear help scientists find phages that would treat the eye infections as well? By the following January, the CDC said at least 50 patients in 11 states had developed superbug infections after using preservative‐free artificial tears. It was a qualified success: The antibiotic-resistant bacteria in five patients were eradicated, while several more patients showed improvements.

☆ Weight gain in children and adults linked to 100% fruit juice, study says
▼ + stars: | 2024-01-16 | by ( Sandee Lamotte | ) edition.cnn.com time to read: +7 min

CNN —Drinking a glass or more of 100% fruit juice each day was linked to a small increase in weight in children and adults, according to a new analysis of prior studies. In such a context, fruit juice is a much better choice than soda, for many reasons,” said Katz in an email. How juice impacts the bodyFor some, the concern over 100% fruit juice may be baffling — fruit is healthy, right? Eating a whole apple, for example, doesn’t spike blood sugar levels because fructose, the sugar found naturally in fruits and some vegetables, is released slowly into the blood. In children, each additional serving per day of 100% fruit juice was associated with a 0.03 higher body mass index, or BMI, change, according to the study.

He was not involved in the latest research but has collaborated with some members of the research team on other primate studies. However, a rhesus monkey was cloned in 1999 using what researchers consider a simpler cloning method. Cloned monkeys can be genetically engineered in complex ways that wild-type monkeys cannot; this has many implications for disease modeling.

Dany Azar/Handout via REUTERS Acquire Licensing RightsWASHINGTON, Dec 5 (Reuters) - Hundreds of thousands of people worldwide are killed annually by malaria and other diseases spread through the bite of mosquitoes, insects that date back to the age of dinosaurs. To their surprise, the male mosquitoes possessed elongated piercing-sucking mouthparts seen now only in females. Some flying insects - tsetse flies, for instance - have hematophagous males. "In all hematophagous insects, we believe that hematophagy was a shift from plant liquid sucking to bloodsucking," Azar said. The researchers said while these are the oldest fossils, mosquitoes probably originated millions of years earlier.

Here are my strategies for reheating meals that taste just as good the second (or third) time around and eating every single portion of everything I cook. Turning to the microwave is often the first response when reheating leftovers, but it's not always the method that will give the most optimal results for most foods. These ovens can reheat food without waiting to preheat, and many offer convection, air frying or one-touch pizza options. What foods work best for microwave reheating? Foods that have a main liquid component, such as soups and stews, are a natural fit for microwave reheating.

☆ How head lice reveal secrets about human origins

CNN —Head lice have been constant, if unwanted, human companions for as long as our species has been around. Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages, with origins predating Homo sapiens. Doing so allowed researchers to detect the hybrid lice and better capture the genetic diversity of head lice. Ascunce said she had hoped the information they gleaned might answer whether Neanderthal head lice are still around today, but the 15 genetic markers, known as “microsatellites,” that they studied in the lice nuclear DNA didn’t reveal that information. “New ongoing studies are being done using whole genome sequences from human lice, so stay tuned for more exciting research on that.”

Researchers have proposed an explanation for how the patterns form based on the "Turing patterns." A question naturally arises: How can distinct color patterns form in the presence of diffusion? Our work suggests that combining the conditions that form Turing patterns with diffusiophoresis could also form the basis of artificial skin patches. Just like adaptive skin patterns in animals, when Turing patterns change — say from hexagons to stripes — this indicates underlying differences in chemical concentrations inside or outside the body. Besides animal skin patterns, Turing patterns are also crucial to other processes such as embryonic development and tumor formation.
