CM Nitish Kumar on Thursday ordered expeditious procurement of TrueNat machines and their installation in all district hospitals for speedy coronavirus test results. The machine yields the result in less than an hour if it is negative, and in the case of positive case, it requires cross-checking with the other method.

This week we hear stories about a new brain imaging technique for newborns, recently uncovered evidence on rice domestication on three continents, and why Canada geese might be migrating into cities, with Online News Editor David Grimm.   Sarah Crespi interviews Sarah Tishkoff of the University of Pennsylvania about the age and diversity of genes related to skin pigment in African genomes.   Listen to previous podcasts.   [Image: Danny Chapman/Flickr; Music: Jeffrey Cook]

Did people domesticate animals? Or did they domesticate themselves? Online News Editor David Grimm talks with Sarah Crespi about a recent study that looked at self-domesticating mice. If they could go it alone, could cats or dogs have done the same in the distant past? Next, Sinan Aral of the Massachusetts Institute of Technology in Cambridge joins Sarah to discuss his work on true and false rumor cascades across all of Twitter, since its inception. He finds that false news travels further, deeper, and faster than true news, regardless of the source of the tweet, the kind of news it was, or whether bots were involved. In a bonus segment recording during a live podcasting event at the AAAS Annual Meeting in Austin, Sarah first speaks with Ben Munson of the University of Minnesota in Minneapolis about markers of gender and sexual orientation in spoken language and then Adrienne Hancock of The George Washington University in Washington, D.C., talks about using what we know about gender and communication to help transgender women change their speech and communication style. Live recordings sessions at the AAAS meeting were supported by funds from the European Commission. This week’s episode was edited by Podigy. Listen to previous podcasts.

Several thousand years ago the volcano under Santorini in Greece—known as Thera—erupted in a tremendous explosion, dusting the nearby Mediterranean civilizations of Crete and Egypt in a layer of white ash. This geological marker could be used to tie together many ancient historical events, but the estimated date could be off by a century. Contributing Correspondent Lizzie Wade joins host Sarah Crespi to talk about a new study that used tree rings to calibrate radiocarbon readings—and get closer to pinning down a date. The findings also suggest that scientists may need to change their standard radiocarbon dating calibration curve. Sarah also talks to Tony Belpaeme of Ghent University in Belgium and Plymouth University in the United Kingdom about his Science Robotics paper that explored whether people are susceptible to peer pressure from robots. Using a classic psychological measure of peer influence, the team found that kids from ages 7 to 9 occasionally gave in to social pressure from robot peers, but adults did not.

It’s incredibly difficult to get an inkling of what is going on inside gas giants Saturn and Jupiter. But with data deliveries from the Cassini and Juno spacecraft, researchers are starting to learn more. Science Staff Writer Paul Voosen talks with host Sarah Crespi about new gravity measurements from Cassini’s last passes around Saturn. Using these data, researchers were able to compare wind patterns on Saturn and Jupiter and measure the mass and age of Saturn’s rings. It turns out the rings are young, relatively speaking—they may have formed as recently as 10 million years ago, after dinosaurs went extinct. Megan Cantwell then talks to science writer Laura Spinney about how researchers are fighting conspiracy theories and political manipulation in the Democratic Republic of the Congo during the country’s ongoing Ebola outbreak. In a first, the government, nongovernmental organizations, and scientists are working with community leaders to fight misinformation—and they might actually be winning.

Speech bubbles are a popular effect but many tutorials rely on presentational HTML or JavaScript. This tutorial contains various forms of speech bubble effect created with CSS 2.1 and enhanced with CSS3. No images, no JavaScript and it can be applied to your existing semantic HTML.

The CSS file used in the demo page is heavily commented so that you can see which lines of code are responsible for each part of the effects.

Demo: Pure CSS speech bubbles

Support: Firefox 3.5+, Safari 4+, Chrome 4+, Opera 10+, IE8+.

Progressive enhancement with pseudo-elements

With HTML as simple as <div>Content</div> or <p>Content</p> you can produce speech bubble effects like this:

Add a child element, for example, <blockquote><p>Quote</p></blockquote> and you can even produce speech bubble effects like this:

I’d encourage you to adapt the examples to your needs and use any other associated elements available to you in your existing HTML document. The key is to use the :before and/or :after pseudo-elements to produce basic shapes.

By applying CSS3 properties such as border-radius and transform you can produce more complex shapes and orientations. This is how the heart-shape in my CSS typography experiment was created.

Example code

This is an example of how to create a basic speech bubble with a few enhancements. For further examples see the demo page and the heavily commented CSS file that it uses.

/* Bubble with an isoceles triangle
------------------------------------------ */

.triangle-isosceles {
  position: relative;
  padding: 15px;
  margin: 1em 0 3em;
  color: #000;
  background: #f3961c;
  border-radius: 10px;
  background: linear-gradient(top, #f9d835, #f3961c);
}

/* creates triangle */
.triangle-isosceles:after {
  content: "";
  display: block; /* reduce the damage in FF3.0 */
  position: absolute;
  bottom: -15px;
  left: 50px;
  width: 0;
  border-width: 15px 15px 0;
  border-style: solid;
  border-color: #f3961c transparent;
}

A note on progressive enhancement

This approach is one of progressive enhancement. Styles are built up in layers from simple coloured boxes, to boxes with a “speech tick” of some kind, to rounded rectangles or circles with gradient backgrounds. Browsers render the styles that they are capable of rendering.

Browsers (such as IE6 and IE7) that do not adequately support CSS 2.1 or those (such as IE8) without support for the necessary CSS3 properties will not look broken; they will simply not get the full speech bubble effect. However…

A warning about Firefox 3.0

Firefox 3.0 supports the necessary CSS 2.1 pseudo-elements but does not support the positioning of generated content.

Some of the examples are close to what I consider to be unacceptably broken in Firefox 3.0. It is the only browser above 2% market share — currently at ~4% as of March 2010 according to NetApplications — that cannot handle even the basic speech bubble effects.

Before applying this technique, consider the importance of Firefox 3.0 support and the percentage of your visitors currently using this browser. Eventually it will become a rare browser but due to it’s partial CSS 2.1 support you should be aware that there is no graceful fallback for Firefox 3.0 when using this technique.
