The use of opioids to soothe the pain of a pulled tooth could be drastically reduced or eliminated altogether from dentistry, say researchers.
Bacteria form biofilms like settlers form cities
Microbiologists have long adopted the language of human settlement to describe how bacteria live and grow: They "invade" and "colonize." Relations dwelling in close proximity are "colonies."
Mercury's 400 C heat may help it make its own ice
It is already hard to believe that there is ice on Mercury, where daytime temperatures reach 400 degrees Celsius, or 750 degrees Fahrenheit. Now an upcoming study says that the Vulcan heat on the planet closest to the sun likely helps make some of that ice.
Weatherwatch: how can we avoid a mighty pile-up in space?
Debris from thousands of disused satellites is in orbit around Earth. It can be buffeted around by space weather. We need better forecastsWhat’s the weather like in Earth’s upper atmosphere today? Most of us only care about how the weather feels on the Earth’s surface, but understanding “space weather” is becoming increasingly important. That’s because small changes in space weather...
Mercury's 400 C heat may help it make its own ice

Despite Mercury's 400 C daytime heat, there is ice at its caps, and now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.
How skin cells embark on a swift yet elaborate death
- ScienceDaily
- 20/3/13 20:53
Scientists have identified the mechanism that allows skin cells to sense changes in their environment, and very quickly respond to reinforce the skin's outermost layer. The findings provide insight into how errors in this process might lead to skin conditions like psoriasis.
How sperm unpack dad's genome so it can merge with mom's

Researchers discover the enzyme SPRK1's role in reorganizing the paternal genome during the first moments of fertilization -- a finding that might help explain infertility cases of unknown cause.
First-time direct proof of chemical reactions in particulates
- ScienceDaily
- 20/3/13 20:53
Researchers have developed a new method to analyze particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other suspended particulate matter. Their findings will help to improve the understanding of global processes involved in cloud formation and...
What can you do with spiral graph? Help understand how galaxies evolve
- ScienceDaily
- 20/3/13 20:53
Researchers have developed a technique to accurately measure the winding arms of spiral galaxies that is so easy, virtually anyone can participate. This new and simple method is currently being applied in a citizen science project, called Spiral Graph, that takes advantage of a person's innate ability to recognize patterns, and ultimately could provide researchers with some insight into how...
How plants sound the alarm about danger
- ScienceDaily
- 20/3/13 20:53
Just like humans and other animals, plants have hormones. One role of plant hormones is to perceive trouble and then signal to the rest of the plant to respond. A multicenter team is reporting new details about how plants respond to a hormone called jasmonic acid, or jasmonate. The findings could help researchers develop crops that are hardier and more able to withstand assault, especially in an...
Call for older people in poor countries to be considered in global responses to COVID-19
- ScienceDaily
- 20/3/13 20:52
Current guidance on coronavirus 'largely ignores' the implications for public health and clinical responses in light of those most at risk, according to an international group of global health experts.
Invisible plastics in water
- ScienceDaily
- 20/3/13 20:52
A research team has found that nanoscale particles of the most commonly used plastics tend to move through the water supply, especially in fresh water, or settle out in wastewater treatment plants, where they end up as sludge, in landfills, and often as fertilizer.
UM professor helps Malaysia develop conservation areas, protect species
Jedediah Brodie has spent a career tromping around tropical rainforests, conducting on-the-ground research in some of the world's most lush and diverse regions.

Invisible plastics in water
A Washington State University research team has found that nanoscale particles of the most commonly used plastics tend to move through the water supply, especially in fresh water, or settle out in wastewater treatment plants, where they end up as sludge, in landfills, and often as fertilizer.
What can you do with spiral graph? Help understand how galaxies evolve
Spiral structure is seen in a variety of natural objects, ranging from plants and animals to tropical cyclones and galaxies. Now researchers at the North Carolina Museum of Natural Sciences have developed a technique to accurately measure the winding arms of spiral galaxies that is so easy, virtually anyone can participate. This new and simple method is currently being applied in a citizen science...
How sperm unpack dad's genome so it can merge with mom's
A sperm enters an egg, an embryo develops and eventually a baby is born. But back up a second—how does the mother's half-genome actually merge with the father's half-genome to form one new human genome? Turns out researchers don't really know that much about these relatively brief, yet crucial, incipient moments in fertilization.
NASA's Terra Satellite observes development of Tropical Storm 22S
NASA's Terra satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of newly formed Tropical Storm 22S, located near northeastern Madagascar.
Three things central bankers can learn from Bitcoin

Herd immunity: will the UK's coronavirus strategy work?
Ministers look to have given up on containment in favour of a novel approach some experts are wary ofCoronavirus: latest updatesHerd immunity is a phrase normally used when large numbers of children have been vaccinated against a disease like measles, reducing the chances that others will get it. As a tactic in fighting a pandemic for which there is no vaccine, it is novel – and some say...

Scientists work toward more reliable prediction of South Asian summer monsoon rainfall for the upcoming 15-30 years
The South Asian summer monsoon (SASM) provides the principal water supply for over a billion people. In good monsoon years, farmers reap a rich harvest, while in bad monsoon years, severe droughts wipe out crops. And heavy rains during monsoon season cause floods and hit economy badly. Policymakers and stakeholders urgently need projection of SASM for the coming 15-30 years —usually termed as...
First-time direct proof of chemical reactions in particulates
Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. Using it, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other suspended particulate matter. In the smog chamber at PSI, they analysed chemical compounds directly in...
