Some students are helping themselves to servings of tuna well beyond the amounts recommended to avoid consuming too much mercury. Researchers surveyed students on their tuna consumption habits and knowledge of mercury exposure risks, and also measured the mercury levels in hair samples. Hair mercury levels were closely correlated with how much tuna the students said they ate. And for some, the measurements were above what is considered a 'level of concern.'

A researcher discovered that medically unnecessary ambulance rides have drastically increased due to the expansion of the Affordable Care Act (ACA). Dispatches for minor injuries like abrasions and muscle sprains have risen by 37% in NYC, an increase equivalent to approximately 239 additional dispatches a month, or 2,868 per year. When patients bear a smaller portion of the cost, researchers argue, they will be more likely to use an ambulance in less emergent situations.

New prostate cancer research shows that adding an interim scan during therapy can help guide a patient's treatment. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging of patients with metastatic castration-resistant prostate cancer after two cycles of lutetium-177 (177Lu)-PSMA radioligand therapy has shown a significant predictive value for patient survival.

Researchers have discovered a mysterious group of neurons in the amygdala -- a key center for emotional processing in the brain -- that stay in an immature, prenatal developmental state throughout childhood. Most of these cells mature rapidly during adolescence, suggesting a key role in the brain's emotional development, but some stay immature throughout life, suggesting new ideas about how the brain keeps its emotional responses flexible throughout life.

A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and older African American research participants.

Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved. Now, researchers have a developed a double-duty hydrogel that both attacks the bacteria and encourages bone regrowth with a single application containing two active components.

Under certain circumstances, a wave can split into several paths, reaching some places with high intensity, while avoiding others almost completely. This kind of 'branched flow' has first been observed in 2001. Scientists have now developed a method to exploit this effect. The core idea of this new approach is to send a wave signal exclusively along one single pre-selected branch, such that the wave is hardly noticeable anywhere else.

Before designing the next generation of soft materials, researchers must first understand how they behave during rapidly changing deformation. In a new study, researchers challenged previous assumptions regarding polymer behavior with newly developed laboratory techniques that measure polymer flow at the molecular level.

Many people suffer from a vitamin D deficiency. This can result in brittle bones and an increased risk of respiratory diseases. Chicken eggs are a natural source of vitamin D and one way to, at least partially, compensate for this deficiency. A team of nutritionists and agricultural scientists has found a new way to further increase the vitamin D content of eggs: by exposing chickens to UV light.

Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Researchers now revealed that the photoreceptor protein rhodopsin forms transient clusters within the disc membranes in retina. These clusters are concentrated in the center of disc membranes, and act as platforms in the process of light to chemical signal conversion.

MIT chemical engineers have devised a new way to create nanoemulsions, very tiny droplets of one liquid suspended within another. They also developed a way to easily convert nanoemulsions to a gel when they reach body temperature, which could be useful for developing materials that can deliver medication when rubbed on skin or injected into the body.
