New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals.

A global database of women scientists is diversifying the face of science

Underrepresentation of women scientists in the public sphere perpetuates the stereotype of the white male scientist and fails both to reflect the true diversity of people practicing science today and to encourage more diversity.

Devil rays may have unknown birthing zone

The discovery of dozens of pregnant giant devil rays tangled in fishing nets in a village along Mexico's Gulf of California could mean the endangered species has a previously unknown birthing zone in nearby waters, a study suggests. If more research confirms the possibility, the zone should be protected and placed off limits to fishing during times each spring when pregnant rays migrate there.

How lifestyle affects our genes

In the past decade, knowledge of how lifestyle affects our genes, a research field called epigenetics, has grown exponentially. Researchers have summarized the state of scientific knowledge within epigenetics linked to obesity and type 2 diabetes.

How light triggers brain activity

Optogenetics uses light to control brain processes. It is based on light-controlled proteins such as channelrhodopsin-2, an ion channel that opens when it's exposed to light, thus activating cellular processes. The researchers have now shed light on its mode

Researchers have found a variety of diseases and other health problems in the second- and third-generation offspring of rats exposed to glyphosate, the world's most popular weed killer. In the first study of its kind, the researchers saw descendants of exposed rats developing prostate, kidney and ovarian diseases, obesity and birth abnormalities.

Strongly agree: The number of response options matter when using a Likert Scale

Researchers often tweak the number of response options in the traditional five-point Likert Scale with little empirical justification for doing so. Now a psychologist has tested the test. Leonard Simms says 'six appears to be the magic number' of responses.

Overlooked molecular machine in cell nucleus may hold key to treating aggressive leukemia

Many people fighting a very aggressive form of acute myeloid leukemia (AML) don't survive more than five years. These very sick patients are often unable to receive the only cure -- a bone marrow transplant. Now, an international team of scientists report on a long-overlooked part of a leukemic cell's internal machinery, where they may have found a key to treating the aggressive blood cancer.

Protecting damaged hearts with microRNAs

Once the heart is formed, its muscle cells have very limited ability to regenerate. After a heart attack, these cells die off and scar tissue forms, potentially setting people up for heart failure. A new study advances the possibility of using microRNAs -- small molecules that regulate gene function -- to regenerate heart muscle. In mice, two microRNAs that are abundant in developing hearts, miR-19a and miR-19b, repaired heart muscle and improved cardiac function after heart attack.

A recent discovery explains a new family of gravitational instabilities in granular particles of different densities that are driven by a gas-channeling mechanism not seen in fluids. The team observed an unexpected Rayleigh-Taylor (R-T)-like instability in which lighter grains rise through heavier grains in the form of 'fingers' and ''granular bubbles, similar to the bubbles that form and rise in lava lamps.
