As tumors grow within an organ, they also release cells that enter the bloodstream. These cells can travel to other organs, seeding new tumors called metastases. MIT engineers have now developed a technique that, for the first time, allows them to measure the generation rate of these circulating tumor cells (CTCs) in mice. Their approach, […]

Getting a quick and accurate reading of an X-ray or some other medical images can be vital to a patient’s health and might even save a life. Obtaining such an assessment depends on the availability of a skilled radiologist and, consequently, a rapid response is not always possible. For that reason, says Ruizhi “Ray” Liao, […]

When it comes to processing vision, the brain is full of noise. Information moves from the eyes through many connections in the brain. Ideally, the same image would be reliably represented the same way each time, but instead different groups of cells in the visual cortex can become stimulated by the same scenes. So how […]

Exercise is healthy. That is common knowledge. But just how rigorous should that exercise be in order to really impact a person’s fitness level? And, if you sit all day at a desk, but still manage to get out and exercise, does that negate your six, seven, or eight hours of sedentary behavior? These were […]

If further research can identify the substances that the bacteria of the gut are making to help muscles grow following exercise, we might be able to use some of those substances to promote the growth of muscles in people suffering from the loss of muscle as typically seen with aging or cancer. That’s according to […]

Scientists have created a photo-electrosynthetic system that allows cyanobacteria to use both light and electricity to convert carbon dioxide into acetate or ethylene.1 The system is more energy efficient than natural photosynthesis and opens new avenues for coupling renewable electricity to photosynthetic microorganisms to sustainably produce fuels. Photosynthesis, which converts carbon dioxide to useful carbon-containing […]

Finger tracing has been used by teachers to help students learn for more than a century. In the early 1900s, education pioneer Montessori encouraged young children to trace over letters of the alphabet made from sandpaper with their index fingers, based on the intuition that a multi-sensory approach (i.e., visual, auditory, tactile, and kinesthetic) to […]

Mechanical thinning alone can calm the intensity of future wildfires for many years, and prescribed burns lengthen thinning’s effectiveness, according to Oregon State University research involving a seasonally dry ponderosa pine forest in northeastern Oregon. Findings of the study, led by OSU research associate James Johnston and published in Forest Ecology and Management, are important […]

The chemical methane, as the largest component in natural gas, is a familiar fuel, but it is also a greenhouse gas many times more potent than carbon dioxide in trapping the sun’s warming rays in the atmosphere. Vehicle engines spew lots of methane, and excess methane is burned up in flares that are a common […]

For decades, the general-purpose central processing unit—the CPU—has been the workhorse of the computer industry. It could handle any task—literally—even if most of those capabilities were unnecessary. This model was all well and good as chips grew smaller, faster and more efficient by the day, but less so as the pace of progress has slowed, […]
