Controlling instabilities gives closer look at chemistry from hypersonic vehicles

Tuesday April 23rd, 2019 08:20:24 PM
While studying the chemical reactions that occur in the flow of gases around a vehicle moving at hypersonic speeds, researchers use a less-is-more method to gain greater understanding of the role of chemical reactions in modifying unsteady flows that occur in the hypersonic flow around a double-wedge shape.

Water walking: The new mode of rock skipping

Tuesday April 23rd, 2019 08:20:19 PM
Researchers not only reveal the physics of how elastic spheres interact with water, but they also lay the foundation for the future design of water-walking drones.

Carbon dioxide from Silicon Valley affects the chemistry of Monterey Bay

Tuesday April 23rd, 2019 06:55:20 PM
Elevated concentrations of carbon dioxide in air flowing out to sea from Silicon Valley and the Salinas Valley could increase the amount of carbon dioxide dissolving in Monterey Bay waters by about 20 percent.

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

Tuesday April 23rd, 2019 06:55:17 PM
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.

New sensor detects rare metals used in smartphones

Tuesday April 23rd, 2019 06:55:14 PM
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.

Experiences of 'ultimate reality' or 'God' confer lasting benefits to mental health

Tuesday April 23rd, 2019 06:55:11 PM
In a survey of thousands of people who reported having experienced personal encounters with God, researchers report that more than two-thirds of self-identified atheists shed that label after their encounter, regardless of whether it was spontaneous or while taking a psychedelic.

New way to 'see' objects accelerates the future of self-driving cars

Tuesday April 23rd, 2019 06:55:08 PM
Researchers have discovered a simple, cost-effective, and accurate new method for equipping self-driving cars with the tools needed to perceive 3D objects in their path.

Researchers see health effects across generations from popular weed killer

Tuesday April 23rd, 2019 05:38:07 PM
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.

Scratching the skin primes the gut for allergic reactions to food, mouse study suggests

Tuesday April 23rd, 2019 05:38:03 PM
Scratching the skin triggers a series of immune responses culminating in an increased number of activated mast cells -- immune cells involved in allergic reactions -- in the small intestine, according to research conducted in mice. This newly identified skin-gut communication helps illuminate the relationship between food allergy and atopic dermatitis (a type of eczema), a disease characterized by dry, itchy skin.

When designing clinical trials for Huntington's disease, first ask the experts

Tuesday April 23rd, 2019 05:37:55 PM
Progress in understanding the genetic mutation responsible for Huntington's disease (HD) and at least some molecular underpinnings of the disease has resulted in a new era of clinical testing of potential treatments. How best to design clinical trials in which HD patients are willing to participate and comply is a question faced by researchers.

The buzz about bumble bees isn't good

Tuesday April 23rd, 2019 05:37:49 PM
While many scientists are focused on the decline of honey bees, relatively few study bumble bees. The good news is that a new study provides an estimate on bumble bee population and distributions across Michigan in the past century. The bad news is that these results are dramatically low, and they mirror what's happening across the Americas, Europe and Asia, too.

New dispersion method to effectively kill biofilm bacteria could improve wound care

Tuesday April 23rd, 2019 05:37:47 PM
Researchers have developed a method to treat bacterial infections which could result in better wound care.

How fish brain cells react to Alzheimer's disease

Tuesday April 23rd, 2019 05:37:29 PM
Researchers have studied the regenerative capacity of zebrafish brain in single cell resolution with the aim of developing novel strategies against Alzheimer's.

Proofreading the book of life: Gene editing made safer

Tuesday April 23rd, 2019 05:37:21 PM
Scientists describe a method of rendering the gene editing tool CRISPR-Cas9 'immunosilent,' potentially allowing the editing and repair of genes to be accomplished reliably and stealthily.

Good mousekeeping: En suite bathroom makes for happier mice

Tuesday April 23rd, 2019 05:37:19 PM
Mice have a strong preference to nest away from their own waste, new research has found. The study showed that mice who were housed in a system of three interconnected cages used separate cages for nesting and eliminating waste. Typically, laboratories house mice in close proximity with their excrement. The study suggests this compromises their welfare and may also negatively affect research data.

Largest collection of coral reef maps ever made

Tuesday April 23rd, 2019 05:37:05 PM
Scientists offer a new way to accurately map coral reefs using a combination of Earth-orbiting satellites and field observations. This first-ever global coral reef atlas contains maps of over 65,000 square kilometers (25,097 square miles) of coral reefs and surrounding habitats.

Atomic beams shoot straighter via cascading silicon peashooters

Tuesday April 23rd, 2019 05:36:55 PM
Atomic beams conjure fantasies of gigantic Space Force canons. But there are real tiny atomic beams that shoot out of newly engineered collimators, a kind of tiny silicon peashooter, that could land in handheld devices. The beams streaming out of them create precise inertia much better than a gyroscope's that could help spacecraft navigate the solar system. The atomic beams from the new collimators could also let physicist cheaply and easily produce exotic quantum mechanical states.

Short period of parental sexual contact prior to pregnancy increases offspring risk of schizophrenia

Tuesday April 23rd, 2019 05:36:53 PM
Children may be at a slightly increased risk of schizophrenia when their parents were in sexual contact for less than three years before conceiving them, according to new research.

Soft tissue makes coral tougher in the face of climate change

Tuesday April 23rd, 2019 05:36:51 PM
A new study has revealed soft tissues that cover the rocky coral skeleton promote the recovery of corals following a bleaching event.

Study unravels mystery of antimicrobial frog secretions

Tuesday April 23rd, 2019 05:36:48 PM
Japanese scientists have identified the molecular mechanism that gives the skin secretions of a species of frog effective antimicrobial properties. Unraveling the molecular mechanism that facilitates antimicrobial activity of these peptides can help us better understand how the defense system of the frog has evolved, and how this can be used to fight microbial infections of medical importance.
