Tackling Wine Allergies
Tech Tackles Wine Allergies -- Discovery News
Some people are allergic to certain wines -- that nice Loire Valley red gives them a rash or headache, or that California Chardonnay makes them sneeze. The University of British Columbia's Wine Research Center might have found a way to solve this problem.
The team at UBC has modified two genes of a strain of yeast called Saccharomyces cerevisiae, which has been used in winemaking for decades (if not centuries). The yeast was modified to eliminate the need for a species of bacteria needed for the winemaking process. That bacteria produces chemicals that cause allergic reactions. About 30 percent of the population has some allergy to wine.

My Comment: What struck me about this article was the following stat .... about 30 percent of the population has some allergy to wine. that's a big market being left out.
New Wi-Fi Hotspots For New York City
A pilot program will turn 10 New York City payphone kiosks into wireless hotspots, with more to follow.
Wi-Fi Hotspots To Revive NYC Payphones -- CNN
(CNN) -- Remember payphones? This might sound crazy, but if New York City has its way, people might actually start using them again to communicate with each other.
The city announced Thursday that it has created Wi-Fi hotspots at 10 payphone kiosks in three of the city's boroughs. It's the first step in a pilot program designed to make wireless access available to as many people as possible in the city.
The kiosks (seven in Manhattan, two in Brooklyn and one in Queens) have antennas that create Wi-Fi hotspots providing free wireless service up to 300 feet away. More will be added in the coming months, according to the blog post announcing the program.

My Comment: If it is free .... it will succeed.
Apple Goes Green Again
Thanks to its non-removable battery, Apple's MacBook Pro with retina display may be difficult to recycle or disassemble.
Apple: No Wait, We're Green Again -- CNN
(CNN) -- Calling its decision to abandon a green certification system for electronics "a mistake," Apple on Friday announced it would again submit its products for EPEAT certification.
"We've recently heard from many loyal Apple customers who were disappointed to learn that we had removed our products from the EPEAT rating system," Apple's senior vice president for hardware engineering, Bob Mansfield, said in a statement. "I recognize that this was a mistake. Starting today, all eligible Apple products are back on EPEAT."

First Evidence Of 'Dark Galaxies' Discovered -- The Telegraph
Astronomers in Chile have observed what appears to be evidence of the existence of dark galaxies, the European Southern Observatory (ESO) announced on Wednesday.
Dark galaxies are small, gas-rich galaxies from the early universe that are believed to be the building blocks of today's bright, star-filled galaxies, said the ESO, an intergovernmental organisation supported by 15 countries.
"For the first time, dark galaxies – an early phase of galaxy formation, predicted by theory but unobserved until now – may have been spotted," the ESO said in a statement.
"Using ESO's Very Large Telescope, an international team thinks they have detected these elusive objects by observing them glowing as they are illuminated by a quasar," it said.

How Did Dinosaurs Mate?
The Joy Of T-Rex: Scientists Show How Dinosaurs Had Sex (Tricky, When You Weigh 30 Tonnes And One Crucial Part Is 12ft Long) -- Daily Mail
Palaeontologists answer many tricky questions about dinosaurs - but perhaps the most interesting is how did 30-ton animals larger than four-storey buildings have sex.
A surprising amount of research has been devoted to the subject - and most researchers have concluded that dinosaurs made love like dogs
'All dinosaurs used the same basic position to mate,' said Dr Beverly Halstead, an English researcher who was one of the first to tackle the subject. 'Mounting from the rear, he put his forelimbs on her shoulders, lifting one hind limb across her back and twisting his tail under hers.'

My Comment: 12 feet long?
Native American Settled The New World In Three Major Waves
Americas 'Settled In Three Waves' -- BBC
The biggest survey of Native American DNA has concluded that the New World was settled in three major waves.
But the majority of today's indigenous Americans descend from a single group of migrants that crossed from Asia to Alaska 15,000 years ago or more.
Previous genetic data have lent support to the idea that America was colonised by a single migrant wave.
An international team of researchers have published their findings in the journal Nature.

Discovery of Chemical That Affects Biological Clock Offers New Way to Treat Diabetes -- Science Daily
ScienceDaily (July 12, 2012) — Biologists at UC San Diego have discovered a chemical that offers a completely new and promising direction for the development of drugs to treat metabolic disorders such as type 2 diabetes -- a major public health concern in the United States due to the current obesity epidemic.
Their discovery, detailed in a paper published July 13 in an advance online issue of the journal Science, initially came as a surprise because the chemical they isolated does not directly control glucose production in the liver, but instead affects the activity of a key protein that regulates the internal mechanisms of our daily night and day activities, which scientists call our circadian rhythm or biological clock.

My Comment: A promising direction to help type 2 diabetes patients.
Robotic Hand Also Doubles As A Human Exoskeleton
Festo's robotic ExoHand also works as a human augmentation device.
Sophisticated Robotic Hand Also Doubles As A Human Exoskeleton -- Singularity Hub
It may be time to jettison the notion that robots in the future will have grippers or claws for hands. The German robotics company Festo recently unveiled the ExoHand, a sophisticated robotic hand that is capable of the fine motor skills that allows the human hand to have a delicate touch or perform complex manipulations.
The ExoHand comes in two forms: as the extremity of a robotic arm or a wearable exoskeleton glove. The system is designed so that the glove can aid assembly line workers performing repetitive tasks with their hands or be used for the remote manipulation of the robotic arm by a user wearing the glove.

Scientists Bring 500 Million-Year-Old Bacteria Back To Life
The new 'chimeric' bacteria has mutated rapidly - and some have become stronger and healthier than today's germs
Jurassic Park In A Petri Dish: Scientists Bring 500 Million-Year-Old Bacteria Back To Life - What Could Possibly Go Wrong? -- Daily Mail
* 'Frankenstein' germ spliced with gene from 500-million-year-old bacteria
* Bacteria is now thriving in lab
* Some of the 'chimeric' E Coli is now stronger than normal bacteria
* Scientists hope to 'restage' evolution
* Will answer questions about how and why organisms evolve
A 500 million-year-old bacteria has been brought back to life in a laboratory at Georgia Tech in an experiment with echoes of Jurassic Park's disastrous recreation of the dinosaurs.
The researchers have resurrected a 500-million-year-old gene and inserted it into a modern E Coli bacteria.
The 'Frankenstein' germ has thrived. In the lab, the creation has now lived through 1,000 generations.

Giant Sunspot Shoots Out Intense, X-Class Solar Flare -- Washington Post
UPDATE, 3:30 p.m.: NOAA’s Space Weather Prediction Center (SWPC) just posted the following:
The R3 (Strong) Radio Blackout today at 12:49 EDT (1649 UTC) was accompanied by an earth-directed CME. Hampered by limited observations of the event, SWPC forecasters are now anticipating the passage of the [coronal mass ejection] around 1:00 a.m. EDT, Saturday, July 14. G1 (minor) Geomagnetic Storm activity is expected to then ensue through the rest of the day.
In short, NOAA is predicting minor effects from this space weather event - no major impacts on the power grid or satellites anticipated - although we remind you forecasting space weather is difficult and surprises are possible. Sky watchers in northern U.S. (and high latitudes) may have an opportunity to see aurora late Friday night into early Saturday morning.

Cybercom chief: Destructive cyber attacks are coming
The commander of the military’s new U.S. Cyber Command said digital attacks are evolving from disrupting network functions to destructive strikes.
Army Gen. Keith Alexander, the Cybercom commander who is also head of the National Security Agency electronic spy service, said current forms of attack emanate from nation states, criminals, hackers, and others, and mainly disrupt temporarily the work of computer networks and systems.
“What I am concerned about and what I think we really need to be concerned about is when these transition from disruptive to destructive attacks, and I think those are coming,” Alexander said during remarks Monday to the American Enterprise Institute.

New Pluto Moon Discovered -- Red Orbit
Scientists announced on Wednesday they have discovered the smallest moon yet, orbiting around the dwarf planet Pluto.
The discovery was made by a team of scientists who used the Hubble Space Telescope to scout out Pluto’s neighborhood ahead of a NASA spacecraft that is scheduled to arrive in 2015.
The new moon, known as P5 currently, appeared as a small fleck in the Hubble images, and scientists believe it is about 6 to 15 miles across.

My Comment: Incredible. This new moon is only 6 - 15 miles across .... but it can still be spotted by the Hubble telescope.
Tree-Rings Prove Climate Was WARMER In Roman And Medieval Times Than It Is Now
Global cooling: It is the first time that researchers have been able to accurately measure trends in global temperature over the last two millennia
Tree-Rings Prove Climate Was WARMER In Roman And Medieval Times Than It Is Now - And World Has Been Cooling For 2,000 Years -- Daily Mail
* Study of semi-fossilised trees gives accurate climate reading back to 138BC
* World was warmer in Roman and Medieval times than it is now
How did the Romans grow grapes in northern England? Perhaps because it was warmer than we thought.
A study suggests the Britain of 2,000 years ago experienced a lengthy period of hotter summers than today.
German researchers used data from tree rings – a key indicator of past climate – to claim the world has been on a ‘long-term cooling trend’ for two millennia until the global warming of the twentieth century.
This cooling was punctuated by a couple of warm spells.

My Comment: More fuel to the climate warming debate.
Truvada Drug Trials Signal 'Turning Point' In The Battle Against AIDS
A trio of new studies highlights the promise and challenges of preventing the spread of HIV, the virus that causes AIDS: Giving anti-AIDS drugs to healthy but high-risk patients can dramatically reduce the risk of infection.
Two studies from Africa in heterosexual patients found that the drugs reduced the rate of HIV infection by 62% to 75%, a success rate that's comparable to results from studies of gay men, according to research in today's New England Journal of Medicine. A third study in African women at high risk of infection, however, was ended early after researchers saw the drugs had no effect on HIV rates, largely because fewer than 40% of study participants took their pills as instructed.
