Scientists have produced a very unusual light show, engineering bacterial cells to fluoresce in synchrony.
The researchers turned the cells into synchronised "genetic clocks" - programming them to switch a fluorescent protein on and off.
These waves of activity could eventually be used to make biological sensors, or to programme cells to release timed doses of medicine.
The researchers report the advance in the journal Nature.
This is well worth a look!

President Obama wants answers on alleged cyber-attacks originating in China on the search giant Google, officials say.
A White House spokesman said Mr Obama wanted "some answers" and agreed those responsible should "face consequences". The comments came after China denounced US Secretary of State Hillary Clinton's criticism of its internet restrictions, saying it was harming relations. Google has said it will decide shortly whether to end its China operations.
The company currently holds about one-third of the Chinese search market, far behind Chinese rival Baidu, which has more than 60%.
'Consequences'
Earlier on Friday, a Chinese foreign ministry spokesman said the US should "respect the facts" and stop making "groundless accusations". "The US has criticised China's policies to administer the internet, and insinuated that China restricts internet freedom," Ma Zhaoxu said. "This runs contrary to the facts and is harmful to China-US relations." The warning from Beijing came after Mrs Clinton said in a speech that the internet had been a "source of tremendous progress" in China, but that any country which restricted free access to information risked "walling themselves off from the progress of the next century". The private sector had a shared responsibility to safeguard freedom of expression and should take a "principled stand" against censorship, she said. Mrs Clinton also called on the Chinese authorities to investigate Google's complaint that hackers in China had tried to infiltrate its software coding and the e-mail accounts of human rights activists, in a "highly sophisticated" attack. "Countries or individuals that engage in cyber-attacks should face consequences and international condemnation," she added.
Speaking to reporters on board Air Force One on Friday, White House spokesman Bill Burton made it clear that President Obama agreed with her. "As the president has said, he continues to be troubled by the cyber-security breach that Google attributes to China," he said. "All we are looking for from China are some answers," he added. Chinese officials have repeatedly said that Google and other foreign internet companies are welcome to operate within China as long as they obeyed the country's laws and traditions. When the California-based company launched google.cn in 2006, it agreed to censor some search results - such as the 1989 Tiananmen Square protests, Tibetan independence or Falun Gong - as required by the Chinese government.
Google now says it is looking at operating an unfiltered search engine within the law in the country, though no changes to filtering have yet been made.
China has more internet users - about 350 million - than any other country and provides a lucrative search engine market worth an estimated $1bn (£614m) last year.
An Irish internet forum which had to shut down after an attack on its user database has been restored.
Boards.ie, which had to shut down on Thursday afternoon, was restored on Friday evening. Part of the database which included members' usernames, email addresses and obfuscated passwords was accessed. The site had to send nearly 300,000 emails to users warning them of the breach and advising them to change their passwords. The site started life as a forum for the computer game Quake in 1998 and has more than 500 forums on a range of topics. According to the most recent ABC internet traffic statistics in November, Boards.ie had more than 20m page views, averaging more than 1.1m page views a day. Boards.ie said that an administrative account had been compromised and used to insert malicious software, which dumped the user table to a public directory from which it was downloaded. Irish police, the Data Protection Commissioner Billy Hawkes and an independent security consultant have been investigating the attack. The site said users who used their Boards.ie password on other sites with the same username/email should change it there as well. During the time the site was down users were kept updated on the social networking site Twitter about developments. Site users have welcomed the return of Boards.ie with one poster noting: "Thank God - my caffeine-free solidarity is over. I had already fallen off my chair in work."

International Amateur Radio Union (IARU) Region II Area C Emergency Coordinator Arnie Coro, CO2KK, reports that as of 0245 UTC on January 13, nothing had been heard from radio amateurs in Haiti, but that the above frequencies were being kept active in case any Haitian hams manage to get on the air, and in case of other related events in surrounding areas, including aftershocks and a possible tsunami.
