From Financial Post:

A laboratory robot called Adam has been hailed as the first machine in history to have discovered new scientific knowledge independently of its human creators.

Adam formed a hypothesis on the genetics of bakers’ yeast and carried out experiments to test its predictions, without intervention from its makers at Aberystwyth University.

The result was a series of “simple but useful” discoveries, confirmed by human scientists, about the gene coding for yeast enzymes. The research is published in the journal Science.

Professor Ross King, the chief creator of Adam, said robots would not supplant human researchers but make their work more productive and interesting.

From Live Science:

Strange lights appeared over Morris County, New Jersey, on Jan. 5 this year. The bright red lights were first noticed in the night sky by an eleven-year-old girl, who pointed out three lights grouped together, and another pair some distance away.

The lights moved silently and slowly, then disappeared one by one.

The girl's father, a pilot, said he was baffled: "I've been in aviation for 20 years and never seen anything like it." Police fielded calls from alarmed residents, and the supposed UFO made national news.

From Science Daily:

ScienceDaily (Apr. 2, 2009) — Scientists have pinned down the constituent of olive oil that gives greatest protection from heart attack and stroke. In a study of the major antioxidants in olive oil, Portuguese researchers showed that one, DHPEA-EDA, protects red blood cells from damage more than any other part of olive oil.

"These findings provide the scientific basis for the clear health benefits that have been seen in people who have olive oil in their diet," says lead researcher Fatima Paiva-Martins, who works at the University of Porto.

Who Gets The Girl? Funny Men Have The Last Laugh...

Photo: Who gets the girl? Funny men like David Walliams, seen with model Lauren Budd, are luckier in love

From The Daily Mail:

It has long been noted that women love a man who can make them laugh - just look at 'sex thimble' Dudley Moore or serial dater David Walliams.

And now scientists believe they know why.

Being funny apparently makes men seem more intelligent, trustworthy - and a better bet for a relationship.

Psychologist Kristofor McCarty said: 'A quick browse of lonely hearts ads will confirm that women look for a good sense of humour in a potential partner - our research may explain why this is the case.'

Mr McCarty drew his conclusions after a study where he asked 45 women to rate the personalities behind a selection of 'lonely hearts' adverts.

Some of these were funny, others were entirely factual.

Fruit Flies Earn No Respect, Except Among Scientists

These humble fruit flies, clinging to a matchstick, may be kitchenpests, but they contribute enormously to biological and medical science. New South Wales Department of Primary Industries/MCT

From McClatchy:

WASHINGTON — That annoying kitchen pest, the fruit fly, occupies an honored place in science and medicine, despite slurs from politicians such as Sen. John McCain and his 2008 sidekick, Sarah Palin.

Scientists have been studying these dinky insects for more than a century, but they say that they're still turning up valuable new information in more than 1,000 laboratories all over the world.

Astronomers Find Hidden Exoplanet in Hubble's Dustbin


From Wired Science:

An exoplanet hidden in the Hubble Space Telescope's archival images has been revealed by data miners using a new technique for spotting the satellites of distant stars.

In search of more information about a known exoplanet orbiting the star HR8799 about 130 light-years from Earth, astronomers turned to the catalog of images Hubble has been amassing for more than 15 years. Using an algorithm that can block the bright light of observed stars allowing the much fainter exoplanets circling them to be seen, the team spotted the planet in an image from 1998.

The Five Ages Of The Brain:


From The New Scientist:

Throughout life our brains undergo more changes than any other part of the body. These can be broadly divided into five stages, each profoundly affecting our abilities and behaviour.

But we are not just passengers in this process, so how can we get the best out of our brains at every stage and pass the best possible organ on to the next? New Scientist investigates

Early Galaxies Surprise With Size

NASA/JPL-Caltech

From Nature News:

Astronomers revise galaxy-formation models with the discovery that early galaxies could have grown fat — fast.

Slurping up cold streams of star fuel, some of the Universe's first galaxies got fat quickly, new observations suggest. The findings could overturn existing models for the formation and evolution of galaxies that predict their slow and steady growth through mergers.

Researchers using the Subaru telescope in Hawaii have identified five distant galaxy clusters that formed five billion years after the Big Bang. They calculated the mass of the biggest galaxy in each of the clusters and found, to their surprise, that the ancient galaxies were roughly as big as the biggest galaxies in equivalent clusters in today's Universe.

From Science Daily:

ScienceDaily (Mar. 31, 2009) — Research by Michigan State University scientists is helping shed light on neutron stars, city-sized globs of ultra-dense matter that occasionally collapse into black holes.

A team led by Betty Tsang, a professor at MSU’s National Superconducting Cyclotron Laboratory, has had some success in measuring a key nuclear quality that may make it easier to describe the outer crusts of such stars.

Humans Losing Touch With Nature


From Live Science:

With so much of life based on electronic representations of reality, humans risk losing touch with nature, says University of Washington psychologist Peter Kahn.

From web cams that offer views of wildlife to virtual tours of the Grand Canyon to robotic pets, modern technology increasingly is encroaching into human connections with the natural world. Kahn and his colleagues believe this intrusion may emerge as one of the central psychological problems of our times.

Giza Pyramids Align Toward City of Sun God

The Giza Pyramids of ancient Egypt, pictured here, were built along an invisible diagonal in orientation toward Heliopolis, the center of worship for the sun god in ancient Egypt, suggests new research.

From Discovery:

March 24, 2009 -- Some of Egypt's most magnificent pyramids were deliberately designed to follow a pattern of invisible diagonal lines, an Italian study has concluded.

According to Giulio Magli, professor of archaeoastronomy at Milan's Polytechnic University, these invisible lines would connect most of the funerary complexes raised by the kings of the Old Kingdom between 2630 and 2323 B.C.

Airport Body Scans Reveal All

Millimeter wave technology produces whole body images (woman at left, man at right) that reveal what's under your clothes, including Metallic or non-metallic devices and objects are displayed, including weapons, explosives and other items that a passenger is carrying on his/her person. The images are viewed by a Transportation Security Officer in a remote location. According to the TSA: To ensure privacy, the setup "has zero storage capability and images will not be printed stored or transmitted. Once the transportation security officer has viewed the image and resolved anomalies, the image is erased from the screen permanently. The officer is unable to print, export, store or transmit the image." Credit: TSA

From Live Science:

New airport security scanners could become a popular alternative to body searches, but have also prompted some privacy concerns.

Whole-body imaging technologies can see through clothing to reveal metallic and non-metallic objects, including weapons or plastic explosives. They also reveal a person's silhouette and the outlines of underwear.

That hasn't stopped security officials from implementing them. The U.S. Transportation Security Agency (TSA) started using whole-body imaging at six airports this year, and plans are in the works to expand it to airports in several more U.S. cities later this year.

From Watts Up With That?

The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower.

2008 was a bear. There were no sunspots observed on 266 of the year’s 366 days (73%). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days: plot. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008.

Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year’s 90 days (87%).

From Science Daily:

ScienceDaily (Mar. 31, 2009) — Chemists reported development of what they termed the first economical, eco-friendly process to convert algae oil into biodiesel fuel — a discovery they predict could one day lead to U.S. independence from petroleum as a fuel.

The study was presented recently at the 237th National Meeting of the American Chemical Society.

One of the problems with current methods for producing biodiesel from algae oil is the processing cost, and the New York researchers say their innovative process is at least 40 percent cheaper than that of others now being used. Supply will not be a problem: There is a limitless amount of algae growing in oceans, lakes, and rivers, throughout the world.

Deformed Skull Suggests Human Ancestors Had Compassion

A newly reconstructed deformed fossil skull suggests our human ancestors probably cared for deformed offspring for years.

From Wired Science:

The skull indicates that the child who lived about 530,000 years ago would have been severely handicapped — and yet survived at least five years and possibly several years longer. That suggests the parents or community provided the child with care, despite his or her obvious deformities.

"Her/his pathological condition was not an impediment to receiv[ing] the same attention as any other Middle Pleistocene Homo child," the the team of Spanish researchers write in the Proceedings of the National Academy of Sciences.

When Did April Fool's Day Begin?

From Live Science:

Though pranksters and joke-lovers in many countries now gleefully prepare to dupe friends and loved ones on April Fool's Day, no one knows exactly when or why, or even where, this tradition began.

A giddy spurt of practical joking seems to have coincided with the coming of spring since the time of the Ancient Romans and Celts, who celebrated a festival of mischief-making. The first mentions of an All Fool's Day (as it was formerly called) came in Europe in the Middle Ages.

Tipping Point In The Media: Global Warming


From Watts Up With That?

Over the last year or so I have been taking an informal survey of a key news metric - Google news searches for the term “global warming.” A year ago, the ratio of alarmist/skeptical articles was close to 100/1. About six months ago, the ratio was 90/10, Two months ago it was 80/20, and today it hit 50/50 for the first time - including the lead skeptical story “A Cooling Trend Toward Global Warming“. One thing that has changed is the rise of blogs written by informed citizens, complemented by the demise of corporate newspapers which make money from keeping people continually alarmed about one thing or another.

From Scientific American:

A Massachusetts college closes down after over 100 students fall ill with norovirus infections.

An outbreak of stomach flu believed to be caused by norovirus has prompted a temporary shutdown of Babson College, a small business college and graduate school in Babson Park, Mass. School officials announced that classes, meetings, athletic events and all other activities would be canceled until Wednesday, when the school is expected to have the outbreak under control.

Dennis Hanno, Babson's undergraduate dean, says that 131 students have visited the school's health services clinic since Wednesday complaining of nausea, vomiting and diarrhea—all symptoms associated with norovirus, a group of viruses formerly known as Norwalk-like viruses. "We saw a high of 40 reported cases on Friday," Hanno told ScientificAmerican.com, noting that the numbers have dropped significantly since then with only four cases reported today. The main concern with this stomach virus, Hanno says, is that it may cause severe dehydration; 12 of the students received fluids intravenously to replenish those lost.

New Theory On Largest Known Mass Extinction In Earth's History

Hypothetically speaking, large areas of the hyper saline Zechstein Sea and its direct environment could have looked like this, which in the Permian Age was situated about where present day Central Europe is. At the end of the Permian Age the Zechstein Sea was irrevocably disconnected from the open sea and the remaining sections of sea soon dried out after that. As a result the microbial-limited halogenated gases from the Zechstein Sea stopped and vegetation was able to regenerate again. The pink colour of the Zechstein Sea was probably brought about by microbes with an extreme preference for salt, as is the case with salt lakes today. In the background sand dunes can be recognised from a landscape with hardly any water. (Credit: Dr. Karsten Kotte/Universität Heidelberg)

From Science Daily:

ScienceDaily (Mar. 31, 2009) — The largest mass extinction in the history of the earth could have been triggered off by giant salt lakes, whose emissions of halogenated gases changed the atmospheric composition so dramatically that vegetation was irretrievably damaged.

At least that is what an international team of scientists has reported in the most recent edition of the Proceedings of the Russian Academy of Sciences (Dokladi Earth Sciences). At the Permian/Triassic boundary, 250 million years ago, about 90 percent of the animal and plant species ashore became extinct. Previously it was thought that volcanic eruptions, the impacts of asteroids, or methane hydrate were instigating causes.
