Hands On Review: iPhone OS 3.0 Chock Full Of Changes

From Ars Technica:

iPhone OS 3.0 is out and it runs on all generations of iPhone and iPod touch. Ars reviews the OS and takes a look at what's in store. If you're not planning to buy a shiny new iPhone 3G S, you may find yourself quite satisfied with your 3G iPhone running the new OS.

The one-word summary for iPhone 3.0 should be "subtle." But don't go thinking that subtlety means boring—the changes that come with Apple's latest mobile OS are plentiful and hidden in many corners of the device. Apple previewed iPhone OS 3.0 to the world in March of this year and again in June at WWDC 2009, but there's no greater experience than playing around with the software and discovering all the surprises yourself. We did just that with iPhone OS 3.0 and discovered that while the cool big changes may get all the press, there are also numerous updates to smaller details should be anything but ignored.

Big Particle Collider Restart Delayed Till October

Large Hadron Collider

From Yahoo News/AP

GENEVA – The world's largest atom smasher will likely be fired up again in October after scientists have carried out tests and put in place further safety measures to prevent a repeat of the faults that sidelined the $10 billion machine shortly after startup last year, the operator said Saturday.

The Large Hadron Collider was meant to restart in late September, but that will probably be pushed back two to three weeks, a spokesman for the European Organization for Nuclear Research said.

From The New Scientist:

It's T-minus one day until Erin Finnegan and Noah Fulmor say "I do" in zero gravity, becoming the first couple to have a weightless wedding. The US couple will exchange vows aboard G-Force One, the "vomit comet" operated by the Zero Gravity Corporation.

Finnegan and Fulmor, who live in New York City, are self-professed space fanatics – as children, both wanted to be astronauts. Finnegan attended space camp, while Fulmor volunteered at a local planetarium. Today Finnegan works in animation production and Fulmor is a legal secretary (see an image of the couple).

Ancient Ice Age, Once Regarded As Brief 'Blip' Found To Have Lasted For 30 Million Years

From Science Daily:

ScienceDaily (June 17, 2009) — Geologists at the University of Leicester have shown that an ancient Ice Age, once regarded as a brief 'blip', in fact lasted for 30 million years.

Their research suggests that during this ancient Ice Age, global warming was curbed through the burial of organic carbon that eventually lead to the formation of oil – including the 'hot shales' of north Africa and Arabia which constitute the world's most productive oil source rock.

Dads Are Key to Making Us Human

From Live Science:

Some 95 percent of male mammals have little to no interaction with their children. Homo sapiens are one of the most notable exceptions, leading some scientists to think fatherhood is an important part of what makes us human.

Most theories for the family involvement of fathers invoke the familiar "Man the Hunter" characterization, in which dad protects and provides for his young.

While fathers do play key roles in securing the physical health of their children, they also can be important for the optimum development of psychological and emotional traits considered to be primarily human, such as empathy, emotional control and the ability to navigate complex social relationships.

Unlike many other animals, humans need their fathers well beyond the act that leads to conception, researchers are coming to realize.

Out Of This World: New Mexico Poised To Break Ground In Construction Of Virgin Spaceport

On it's way: This conceptual image shows how Spaceport America
is expected to look at completion in 2010

From The Daily Mail:

The tantalising prospect of escaping the Earth’s atmosphere and experiencing weightlessness has been in the pipeline for two years. And now it’s officially arrived.

Workers in New Mexico have broken ground in the construction of a terminal and hanger facility for the world’s first rocket spaceport for sending wealthy customers to the edge of space.

Members of the general are being tempted with the ‘most incredible experience of their lives’ for $200,000 (£122,000) from as early as 2010.

Bears And Other Predators Invade U.S. Neighborhoods

From Popular Mechanics:

As once-threatened animal populations including black bears, mountain lions and alligators rebound and people move into former wildlands, predators are showing up precisely where they don't belong: in backyards. And the wildlife isn't as afraid of us as we might think. Welcome to the food chain.

It was the perfect ending to a perfect afternoon. Gary Mann and his girlfriend Helen were watching the sun go down after a satisfying day clearing brush in the backyard of Mann’s home in Sutter Creek, Calif. A pile of branches and twigs was burning merrily, throwing shadows into the growing darkness as the couple’s three dogs—a 50-pound Shar-Pei named Tigger and a pair of Rottweiler mixes, Takota and Tenaya—played at their feet.

Herschel Space Telescope's First Images Give Promising Glimpse Of What's To Come

Figure A: Herschel Composite : Herschel's test view of M51 ESA

From PopSci.com:

Test images show M51 galaxy in more detail than predecessors could

Herschel, the largest infrared space telescope yet flown, was launched a month ago by the ESA and was not expected to deliver images for another few weeks. It has, however, already produced images- in three colors- of M51, ‘the whirlpool galaxy,’ from a test observation run. The goal of the test was to get a large image and a sense of what Herschel will deliver in the future.

Remaining H1N1 Questions

From Time:

The H1N1 flu seems a far cry from the mass killer it was feared to be when it first emerged in Mexico in April. While it has since infected more than 12,000 people in 43 countries, including more than 6,500 in the U.S., it has so far killed just 86 victims. Health officials are still on high alert, however; the disease continues to spread, with a batch of new cases in Japan in mid-May that could be enough to prompt the World Health Organization (WHO) to declare an official pandemic.

From Science Daily:

ScienceDaily (June 19, 2009) — The ability to learn and to establish new memories is essential to our daily existence and identity; enabling us to navigate through the world. A new study by researchers at the Montreal Neurological Institute and Hospital (The Neuro), McGill University and University of California, Los Angeles has captured an image for the first time of a mechanism, specifically protein translation, which underlies long-term memory formation.

The finding provides the first visual evidence that when a new memory is formed new proteins are made locally at the synapse - the connection between nerve cells - increasing the strength of the synaptic connection and reinforcing the memory. The study published in Science, is important for understanding how memory traces are created and the ability to monitor it in real time will allow a detailed understanding of how memories are formed.

'New' Brazilian Flu Strain Is A False Alarm

From New Scientist:

Take a jumpy media, throw in a statement hastily translated from Portuguese, and what have you got? A "new" and potentially deadly strain of H1N1 influenza in Brazil, according to a rash of news stories that appeared earlier today.

"It was not yet known whether the new strain was more aggressive than the current A(H1N1) virus which has been declared pandemic by the World Health Organization," reported Agence France Presse, setting the mood for a new round of pandemic panic.

But this "new" strain is nothing of the sort. In fact, the sequence of its gene for the haemagglutinin surface protein, deposited in the GenBank database, is the same as isolates from several other countries. "[It] has nothing surprising about it and is identical to others," Richard Webby of St Jude Children's Research Hospital in Memphis, Tennessee, told New Scientist.

Mammoths Roamed Britain Until Just 14,000 Years Ago ... And We Didn't Kill Them Off

Chilling end? A lone mammoth in the Ice Age as visualised on the BBC Walking With Beasts programme. But the new research shows the beasts outlived the big freeze

From The Daily Mail:

Woolly mammoths survived in Britain thousands of years later than scientists realised - and may have been killed off by climate change rather than hunters.

A study of mammoth fossils found in Shropshire suggests the gigantic beasts became extinct in north-western Europe no more than 14,000 years ago - shaving a full 7,000 years off the timespan since they were thought to be alive.

It means the species may have survived the efforts of hunters at the height of the Ice Age only to be wiped out when their grazing land was overtaken by forest.

us grip more firmly may not be true. (/ABC News)

From ABC News/New Scientist:

Mystery Surrounding the Reason for Fingerprints Remains

The long-held notion that fingerprints marks help us grip more firmly appears to be wrong. Instead, a new study finds that the marks actually reduce the friction between skin and surfaces.

"Because there are all the gaps between the fingerprints, what they do is reduce the contact area with the surface," says Roland Ennos, a biomechanicist at the University of Manchester, UK, who led the study with colleague Peter Warman.

From Live Science:

The fossilized remains of a tiny 100 million-year-old crustacean reveal evidence of what to her at least would have been giant sperm, measuring perhaps as long as her body.

While the sperm itself was not preserved, 3-D images of the female's specialized receptacles indicate she had just finished having sex and that they were filled with sperm that has since degraded. (The oldest direct evidence of sperm comes from a springtail living some 40 million years ago, according to the researchers.)

From Science Daily:

ScienceDaily (June 17, 2009) — Nanoparticles specially engineered by University of Central Florida Assistant Professor J. Manuel Perez and his colleagues could someday target and destroy tumors, sparing patients from toxic, whole-body chemotherapies.

Perez and his team used a drug called Taxol for their cell culture studies, recently published in the journal Small, because it is one of the most widely used chemotherapeutic drugs. Taxol normally causes many negative side effects because it travels throughout the body and damages healthy tissue as well as cancer cells.

NASA Probes Possibility Of Shuttle Sabotage

From MSNBC/Space.com:

Agency expects technical glitch, but some may have motive to delay launch.

NASA does not suspect sabotage was behind the glitch that twice delayed the launch of the space shuttle Endeavour recently. But, as with any problem without an apparent solution, the space agency is investigating all possible explanations, including intentional tampering, officials said.

Endeavour's STS-127 mission was supposed to lift off June 13, but a leak of hydrogen gas from a pipe attached to the shuttle's fuel tank kept the vehicle grounded. NASA tried to launch Endeavour a second time on Wednesday, but again the leak appeared, even after workers replaced the leaky seal between the pipe and the shuttle.

From Yahoo News/Space:

Nearly 40 years after humans first set foot on the lunar surface, NASA is gearing up to go back with the planned launch today of two unmanned scouts, the robotic vanguard for the first U.S. return to the moon in a decade.

An Atlas 5 rocket is poised to launch the two probes, a powerful lunar orbiter and a smaller spacecraft that will hunt for water ice by crashing into the moon, at about 5:12 p.m. EDT (2112 GMT) today from the Cape Canaveral Air Force Station in Florida. The mission, NASA hopes, will lay the foundation for its plan to return astronauts to the moon by 2020.

Dogs Are Smarter Than Cats, Research Shows

From The Telegraph:

The thought processes of 15 cats were tested by attaching food to the end of lengths of string and observing whether they could figure out that pulling the line brought the treats closer.

The cats had no problem with tackling single pieces of string. However, when faced with two options, experts discovered that unlike their canine counterparts, cats were unable to consistently pick a baited string over a dummy.

From Eurekalert:

First unambiguous evidence for shorelines on the surface of Mars, say researchers.

A University of Colorado at Boulder research team has discovered the first definitive evidence of shorelines on Mars, an indication of a deep, ancient lake there and a finding with implications for the discovery of past life on the Red Planet.

Estimated to be more than 3 billion years old, the lake appears to have covered as much as 80 square miles and was up to 1,500 feet deep -- roughly the equivalent of Lake Champlain bordering the United States and Canada, said CU-Boulder Research Associate Gaetano Di Achille, who led the study. The shoreline evidence, found along a broad delta, included a series of alternating ridges and troughs thought to be surviving remnants of beach deposits.

From Science Daily:

ScienceDaily (June 16, 2009) — The red supergiant star Betelgeuse, the bright reddish star in the constellation Orion, has steadily shrunk over the past 15 years, according to University of California, Berkeley, researchers.

Long-term monitoring by UC Berkeley's Infrared Spatial Interferometer (ISI) on the top of Mt. Wilson in Southern California shows that Betelgeuse (bet' el juz), which is so big that in our solar system it would reach to the orbit of Jupiter, has shrunk in diameter by more than 15 percent since 1993.
