The future of smallsats: The smallest satellites of the world going to ready for the very next generation

The big news is the small satellite front of the world going to ready for the very next generation. From super secret agencies & the U.S. military to academia & private firms, as well as world space agencies & NASA, ultra small satellites are the big thing.

Cornell University has begun to delve into a postage stamp size satellite on a chip design, called Sprite, envisioning a swarm of these tiny probes exploring planetary atmospheres for organic compounds.

Call them a powerful force in the universe. Smallsats have already shown their ability to monitor disasters, study Earth's environment & support agriculture, cartography & earth science missions.

The future of smallsats, there will be growth, new missions, & new ways of working together, said Bille,expressing his own views & not speaking for Booz Allen Hamilton policy. CubeSats are like the personal computer of this industry.

Hunsaker's personal crystal ball predicts networked satellites with individual IP addresses controlled through the Internet & providing individualized positioning, communications, social & multimedia capability.Perhaps just like personal computing & cell phones that have common utility among individual consumers today, smallsats will also follow that trend, said colleague Tom Hunsaker, also an associate at Booz Allen Hamilton.

Bille concluded: The age of microspacecraft is on solid ground now. There's a definite trend toward putting small things together to do big accomplishments.

Huge comet crash closely avoided in 1883

A huge comet closely missed hitting the Earth when it passed within 5,000 miles of us in 1883.

Astronomers have been examining a photograph of the comet taken in 1883 by Mexican astronomer Jose Banilla. At the time it was hailed as the first photograph of a UFO. The object would have been 8 times the mass of Haley's comet & would have wrought untold devastation if it had hit us, may be destroy mankind!

But now scientists from the Universidad Nacional Autonoma de Mexico believe it could have been a massive comet that came close to hitting the Earth with a similar mass to the object that killed the dinosaurs.

Mexican scientists believe this photograph taken in 1883 shows a comet that came shut to hitting the earth.

Using the time that it took the object to cross the sun combined with the location of Bonilla's observatory, the report calculated that the object would be at most 8,000km away, & possibly much less.
'The only bodies in the Solar System which are enclosed by a bright murkiness are the comets, so it is accurate to suppose that the objects seen by Bonilla were small comets, believed the scientists.

As well as being shockingly close to earth, the scientists think that the comet could have had the same group as the object that wiped out the dinosaurs eight times the mass of Halley's comet.
The report's claims have been questioned, though as a comet breaking up so shut to earth should have resulted in a meteor shower, & no astronomers detected one.

Ultrasound Help For Heal Broken Bones

Scottish doctors are using ultrasound to help speed the recovery of broken bones by stimulating bone regeneration through cell vibration. And the sound frequency & pulse rate of the ultrasound is different than that used on pregnant women, but the technology is the same. The transducer gets a coating of water based gel, & is then slipped into a strap that holds it on the break, stimulating cellular activity.

Doctors found that the ultrasound therapy can lower recovery time by more than one third.

Brain waves to track sleep quality with a new app use !!

TOKYO, Oct 10 (coolblognews.com | Latest news update 24x7) - A new app that aims to improve both the quantity & quality of sleep uses brainwaves to track the amount of time spent in different stages of sleep.

Called Sleep Manager, the app synchronizes with a headset that measures brain activity, eye movement & other signals in light, deep & REM (rapid eye movement) sleep.

"The thing about sleep is that it's not just about how much you get - it's about the quality of your sleep," said Ben Rubin, co-founder of Zeo, which makes the app.

"In general, you want to optimize to get as much REM & deep sleep as possible."

A soft-sensor headband measures brainwave activity, muscle tone & eye movements, the same signals that would be taken by a professional sleep lab, but at a consumer level.

The signals are relayed through Bluetooth to the user's iPhone, iPad, or Android smartphone & uploaded to Zeo's website.

Rubin said that sleep tracking is only the beginning. After benchmarking sleep quality, Zeo uses this information to coach the user's sleep habits.

Studies have shown that when people wake up during the light sleep phase they are more refreshed, so the app has the ability to rouse users while in this state.

It also syncs with other apps such as RunKeeper, a running application, & DailyBurn, a nutrition planning app, to allow users to see how their sleep quality relates to their fitness & diets.

But not everyone is convinced that Zeo can provide accurate sleep data.

Rubin agrees there are limitations to the measurements that can be done but he said the app comes close to replicating a sleep lab.

"If you have two experts in a sleep lab scoring the same record, they agree with each other about 83 percent of the time," said Rubin. "Zeo agrees with those guys about 75 percent of the time. So we're about 7/8th as accurate as a full sleep lab," he added.

The company has an in-house sleep expert on their team, as well as an advisory board made up of sleep experts from Harvard University & the University of Colorado Bolder.

List of Seven Foods That Help You Lose Weight

Don't get sucked into the idea that food is your enemy when you're trying to lose weight. In fact, it's just the opposite: Befriend the right foods, & the pounds are much more likely to peel off than if you just try to cut calories across the board. Here, seven foods known to nutritionists to boost your body's fat-burning potential.
1. Oats

Wait a minute -- aren't oats a carb? Yes & no. Oats are a whole grain, & they're high on what nutritionists call the "satiety index," meaning oats have tremendous power to make you feel full. Not only that, they're also high in soluble fiber, so they cut cholesterol & blood fat. Oats digest slowly, so they don't raise your blood sugar, & they keep you feeling filled up well into the late morning. Old-fashioned steel-cut & rolled oats, with up to 5 grams of fiber per serving, are best, but even instant oatmeal has 3 to 4 grams of fiber per serving.
2. Eggs

Nutritionists have been trying for some years to restore the reputation of the lowly egg. No longer thought to be a cholesterol-booster (eggs contain a different type of cholesterol than that in humans), eggs are a concentrated form of animal protein without the added fat that comes with meat. Dietary studies have repeatedly found that when people eat an egg every morning in addition to (or instead of) toast or cereal, they lose twice as much weight as those who eat a breakfast that's dominated by carbs.
3. Skim milk

Studies in reputable publications such as the Journal of Obesity (in addition to the controversial ones funded by the National Dairy Council) show that the combination of calcium, vitamin D, & low-fat protein in skim milk & nonfat yogurt trigger weight loss & help build & maintain lean muscle.

4. Apples

To keep the pounds at bay, eat an apple -- or two -- a day. Numerous studies have found that eating an apple a half hour to an hour before a meal has the result of cutting the calories of the meal. Why? The fiber in the apple makes you feel full, so you eat less. Recent research suggests eating apples has other benefits, too; the antioxidants in apples appear to prevent metabolic syndrome, the combination of high cholesterol, high blood pressure, & prediabetes that tends to accompany thickening around the waist. Also, apples are high in pectin, which binds with water & limits the amount of fat your cells can absorb.
5. Red meat

Not exactly what you think of as a diet food, right? But research in the American Journal of Clinical Nutrition compared diet results for women who ate red meat & those who didn't, & the meat-eaters lost more weight. Experts think the dense protein in lean red meat helps you maintain muscle mass -- but of course this assumes you're exercising to build that muscle.
6. Cinnamon

This simple spice appears to have the power to help your body metabolize sugar, according to surprising data that came out of a USDA study involving diabetics. Eating as little as 1/4 to 2 teaspoons of cinnamon a day was found to reduce blood sugar levels & cut cholesterol from 10 to 25 percent. So add cinnamon to smoothies, sprinkle it on your cereal, or flavor your coffee with it -- particularly if you take your coffee with cream & sugar. The cinnamon will boost the health benefits of the coffee while helping your body rid itself of the added sugars.
7. Almonds & almond butter

Another counterintuitive choice; aren't nuts & nut butters supposed to be incredibly fattening? Well, almonds are calorie-dense, but they also pack a huge nutritional punch -- & they're particularly effective in counteracting cholesterol & triglycerides. One study in the American Journal of Clinical Nutrition found that eating almonds was as effective as taking a statin. Spreading almond butter on your morning toast gives you a nice protein boost while preventing the carbs in the toast from spiking your blood sugar.

Most Likely We Ignore Cancer Symptoms

Symptoms of cancer you might overlook
Chest pain doesn't necessarily mean cancer, but it's an early sign for some patients.

Routine tests & checkups, like pap smears & colonoscopies, are important - but don't rely on tests alone to protect you from cancer. It's just as important to listen to your body & notice anything that's different, odd, or unexplainable. Although many of these symptoms could be caused by less serious conditions, they're worth getting checked out if they persist. You don't want to join the ranks of cancer patients who realize too late that symptoms they'd noticed for a long time could have sounded the alarm earlier, when cancer was easier to cure.

10 Things Your Skin Says About Your Health
For Both Men & Women

Wheezing or Shortness of Breath

One of the first signs lung cancer patients remember noticing when they look back is the inability to catch their breath. "I couldn't even walk across the yard without wheezing. I thought I had asthma, but how come I didn't have it before?" is how one woman described it. Thyroid cancer can also cause breathing problems if a nodule or tumor begins to press on the trachea, or windpipe. Any breathing difficulties that persist are reason to visit the doctor.

Swallowing Problems or Hoarseness

Most commonly associated with esophageal or throat cancer, difficulty swallowing is sometimes one of the first signs of lung cancer, too. A hoarse or low, husky voice or the feeling of something pressing on the throat can be an early indicator of thyroid cancer or a precancerous thyroid nodule, as can the feeling of having something stuck in your windpipe.

Frequent Fevers or Infections

These can be signs of leukemia, a cancer of the blood cells that starts in the bone marrow. Leukemia causes the marrow to produce abnormal white blood cells, which crowd out healthy white cells, sapping the body's infection-fighting capabilities. Often, doctors diagnose leukemia only after the patient has been in a number of times complaining of fever, achiness, & flu-like symptoms over an extended period of time.

Upset Stomach

As simple as it sounds, a good old-fashioned bellyache is what tipped off a number of lucky folks, whose doctors ordered ultrasounds & discovered early that they had tumors on their livers. Stomach cramps or frequent upset stomachs may indicate colorectal cancer; many cancer patients say their doctors thought they had ulcers.

Weakness & Fatigue

"I kept having to sit down at work, & one night I was too tired to drive home," said one woman in describing the fatigue that led her to discover she had leukemia. Generalized fatigue & weakness is a symptom of so many different kinds of cancer that you'll need to look at it in combination with other symptoms. But any time you feel exhausted without explanation & it doesn't respond to getting more sleep, talk to your doctor.

Unexplained Weight Loss

If you notice the pounds coming off & you haven't made changes to your diet or exercise regime, you need to ask why. Weight loss is an early sign of colon & other digestive cancers; it's also a sign of cancer that's spread to the liver, affecting your appetite & the ability of your body to rid itself of wastes.

Changes in Fingernails

Unexplained changes to the fingernails can be a sign of several types of cancer. A brown or black streak or dot under the nail can indicate skin cancer, while newly discovered "clubbing" -- enlargement of the ends of the fingers, with nails that curve down over the tips -- can be a sign of lung cancer. Pale or white nails can be an indication that your liver is not functioning properly, sometimes a sign of liver cancer.

Chronic "Acid Stomach" or Feeling Full After a Small Meal

The most common early sign of stomach cancer is pain in the upper or middle abdomen that feels like gas or heartburn. It may be aggravated by eating, so that you feel full when you haven't actually eaten much. What's particularly confusing is that the pain can be relieved by antacids, falsely confirming your conclusion that it was caused by acid in the stomach, when it's more than that. If you have frequent bouts of acid stomach, an unexplained abdominal ache, or a full feeling after meals even when you're eating less than normal, call your doctor.

Chronic Heartburn

If you just ate half a pizza, heartburn is expected. But if you have frequent episodes of heartburn or a constant low-level feeling of pain in the chest after eating, call your doctor & ask about screening for esophageal cancer. Gastroesophageal reflux disease (GERD) -- a condition in which stomach acid rises into the esophagus, causing heartburn & an acidic taste in the throat -- can trigger a condition called Barrett's esophagus, which can be a precursor of esophageal cancer.

Bowel Problems

Constipation, diarrhea, & changes in stools can all be signs of cancer. As with many other cancer symptoms, the way to tell if this is cause for concern is if it goes on for more than a few days without a clear cause, such as flu or food poisoning. People diagnosed with colon cancer say they noticed more frequent stools, as well as a feeling that their bowels weren't emptying completely. One of the early signs of pancreatic cancer is fatty stools, which can be recognized as frequent, large stools that are paler than normal & smelly. This is a sign that your body's not absorbing your food normally, & it should be brought to your doctor's attention.

New innovation is coming up: The Particular Brain Fold That Helps People Distinguish between Imagination and Reality

Did you actually open the refrigerator a few minutes ago, or were you just thinking about it & imagined that you did? If you can remember correctly, you might have an extra fold in your brain.

A fold in the front brain called the paracingulate sulcus, or PCS, can apparently help people more accurately remember whether something was imagined or really happened, or which person actually said something. It's one of the final structural folds to develop before birth, & its size varies greatly in the general population, according to researchers at the University of Cambridge. People with the fold were significantly better at memory tasks than people without the fold, the researchers say.

The study, which was published in the Journal of Neuroscience, involved 53 healthy adult volunteers with no reported history of cognitive difficulties, according to a Cambridge news release. & everyone thought they had a good memory before the tests.

Participants were chosen based on MRI scans that showed a clear presence or absence of the PCS fold. Then they were presented with word pairs & half-pairs — like “Laurel & Hardy” or “Laurel & ?” In the second test, they were asked to imagine the other word, & then either they or the study leader actually said the word aloud.

Then they had a memory test, where they tried to remember whether they had actually seen the second word or just imagined it, & which person said the word out loud, Cambridge says. People with a PCS remembered correctly a lot more often.

This work has implications for some mental disorders like schizophrenia, in which the line between reality & imagination is unclear to the patient. In other studies, schizophrenic patients reportedly have had reduced PCS areas, according to Jon Simons of Cambridge’s Experimental Psychology department & Behavioural & Clinical Neuroscience Institute.

What to do about this isn’t clear — because the fold happens so shortly before birth, it’s not something that can be physically changed. But understanding the PCS’ role in memory & reality perception could have some impact on drug treatments for mental disorders.

The Future Arrives Next Week

TRSF, an anthology of original science fiction stories, is in stores on October 4.



Back in May, we told you that Technology Review was planning to publish an collection of all-new near-future science fiction stories, grounded in the kinds of technological breakthroughs that we report on here every day. Now the TRSF is almost here—you can preorder a copy today, or wait till it goes on sale on newstands next Tuesday. (Digital editions will be available soon after.)

We've got an amazing selection of writers from around the world, including legends like Pat Cadigan & Joe Haldeman, current stars like Cory Doctorow & Elizabeth Bear, & emerging talents like Vandana Singh & Ma Boyong (this is Boyong's first time appearing in English).

For a full rundown of authors,visit the TRSF microsite, which also has a video describing how the cover of the TRSF was created by the iconic science fiction illustrator, Chris Foss. This is Foss's first major U.S. commission in recent years, & we've also reproduced six of his classic covers within the pages of the TRSF.

The 12 stories in the TRSF range from a light-hearted look at the (almost certainly) inevitable future of kitchen appliances talking to each other, to a more worrisome tale of a researcher fighting her company's attempts to turn therapeutic tool into a mind control technology. They all fulfill the goal of the TRSF: to showcase thought provoking science fiction that explores some of the implications of technological developments in ways that journalism cannot.

UFO sightings on the increase

According to an organization that tracks UFO reports, this summer has been an especially busy period for UFO sightings. The Mutual UFO Network (MUFON) noted that sightings increased over the past six weeks, with some states more than doubling their normal numbers.

Are we on the cusp of an alien invasion? Or maybe people just have more time on their hands to spot —&report — strange things in the sky?

MUFON International Director Clifford Clift told Life's Little Mysteries that he's not sure what to make of the data at this point. It could be the start of something big, or it could merely be a computer glitch that accidentally counted some reports twice. Another possibility is that we're simply in the midst of a "UFO flap," one of many periodic increases in sightings over the years.

There are several reasons UFOs might appear in flaps, or clusters. One is that objects in the sky are usually seen by many people, especially when they appear over urban areas. UFOs typically don't hover close to Earth or in someone's back yard; instead, they are often sighted high in the sky — just far enough away so that we can't see details or get sharp photos.

Thus, whatever a particular UFO really is — a plane, a comet, an extraterrestrial spacecraft or something else — that one object or strange light in the sky could trigger hundreds, or even thousands, of reports.&even reports of the same object will probably differ depending on the reporter's perspective.

So if there were hundreds of UFO reports in a state during a given period, it's important to know how those reports were categorized because it might mean hundreds of different UFOs were sighted by single individuals, or that one UFO was sighted by hundreds of people.

There are also psychological&social explanations. Sightings are often fueled by the mass media; people read about mysterious things or see TV shows about them,&interest or concern about them spreads from person to person. It's not that anyone is hoaxing or making up sightings: Research has shown that if you tell people what to look for (a phenomenon called "priming"), people will often see what they are looking for — whether those things exist or not.

As Clift noted, "It's likely that the media&(alien-themed) movies that are coming out, like 'Apollo 18 '&'Paul,' are piquing people's interest in UFOs." People hear about UFOs,&for a while they tend to look at the sky more often, wondering if they might have their own sighting.&precisely because people are spending more time looking at the sky, they will for the first time notice (normal) lights&objects that have always been there.

So it may not be that UFOs are actually appearing more often, but instead we're noticing them more. An identical process can be found in the medical field, where an increase in reports of a disease may not represent an increase in the actual number of cases, but instead reflects more public awareness of the disease or better screening techniques. In other words, scientists know that just because more people report a phenomenon does not necessarily mean the phenomenon is occurring more often.

Why might UFOs be seen more often in the summer months? One possibility is that people spend more time outdoors; we spend warm nights outside at parties&barbecues, thus we have more opportunity to notice things in the sky than in the winter when we're inside watching television. That said, Clift pointed out that his organization doesn't normally see such dramatic seasonal increases in reports.

Whether the increase in sightings is rooted in reality, a computer glitch or psychological&social influences remains to be seen. One thing is certain: This is not the first time that UFO reports have increased,&it won't be the last.
