US life expectancy surpasses 78, a new record

tpelia@yahoo.com (Tom Elia) — Fri, 18 Mar 2011 13:21:00 -0600

Clearly, Obamacare is the reason!

From AP:

U.S. life expectancy has hit another all-time high, rising above 78 years. The estimate of 78 years and 2 months is for a baby born in 2009, and comes from a preliminary report released Wednesday by the Centers for Disease Control and Prevention.
...

The infant mortality rate hit a record low of 6.42 deaths per 1,000 live births, a drop of nearly 3 percent from 2008. ...Overall male life expectancy is roughly 75 1/2 , for females it's about 80 1/2.

Global Warming Update

paulsgeary@yahoo.com (Paul Geary) — Wed, 22 Dec 2010 00:03:00 -0700

If you are in one of the many places getting brutal winter weather, don't be selfish and root for warmth. 2010 has been already one of the warmest years, if not the warmest, said The New York Times back in October.

And the ramifications are frightening:

Signs of warming were evident in the opening of the Northwest Passage and Northeast Passage to shipping, the third straight year that these normally ice-choked waterways were extensively ice-free in the summer.

The melting ice continues to attract commercial shipping to the Arctic...

In North America, warming was especially pronounced in Alaska, where researchers recently announced that the growing season for the state's interior had expanded from 85 days in the early 20th century to 123 days today.

So quit your selfish bitching and put up with winter.

Universe might hold three times more stars than previously thought

tpelia@yahoo.com (Tom Elia) — Sat, 04 Dec 2010 00:03:00 -0700

The Christian Science Monitor's Pete Spotts reports:

A new study suggests that a specific kind of galaxy might hold 10 times more red dwarf stars than estimated. That would triple projections for the number of stars in the observable universe, with implications for explanations of how stars and galaxies form and evolve.

New Life Form Discovered?

tpelia@yahoo.com (Tom Elia) — Fri, 03 Dec 2010 00:02:00 -0700

From NASA:

NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth.

Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.

"The definition of life has just expanded," said Ed Weiler, NASA's associate administrator for the Science Mission Directorate at the agency's Headquarters in Washington. "As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it."

Human brain has more switches than all computers on Earth

tpelia@yahoo.com (Tom Elia) — Fri, 19 Nov 2010 00:02:00 -0700

Cnet's Elizabeth Armstrong Moore reports: (emphasis added)

The human brain is truly awesome.

A typical, healthy one houses some 200 billion nerve cells, which are connected to one another via hundreds of trillions of synapses. Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies.
...

[Stanford University School of Medicine researchers have] found that the brain's complexity is beyond anything they'd imagined, almost to the point of being beyond belief, says Stephen Smith, a professor of molecular and cellular physiology and senior author of the paper describing the study:
One synapse, by itself, is more like a microprocessor--with both memory-storage and information-processing elements--than a mere on/off switch. In fact, one synapse may contain on the order of 1,000 molecular-scale switches. A single human brain has more switches than all the computers and routers and Internet connections on Earth.

Trees Infused With Glowing Nanoparticles Could Replace Streetlights

tpelia@yahoo.com (Tom Elia) — Tue, 16 Nov 2010 00:02:00 -0700

Popular Science's Julie Beck reports:

Taiwanese researchers have come up with the elegant idea of replacing streetlights with trees, by implanting their leaves with gold nanoparticles. This causes the leaves to give off a red glow, lighting the road for passersby without the need for electric power. This ingenious triple threat of an idea could simultaneously reduce carbon emissions, cut electricity costs and reduce light pollution, without sacrificing the safety that streetlights bring.

Computers set for quantum leap

tpelia@yahoo.com (Tom Elia) — Sat, 18 Sep 2010 00:02:00 -0600

The Financial Times' Clive Cookson reports some really good news:

A new photonic chip that works on light rather than electricity has been built by an international research team, paving the way for the production of ultra-fast quantum computers with capabilities far beyond today's devices.

The longer you sit, the earlier you die

tpelia@yahoo.com (Tom Elia) — Sun, 29 Aug 2010 00:02:00 -0600

The Orlando Sentinel's Marissa Cevallos reports:

... people who sit more than 6 hours a day are more likely to die earlier.

That's even for people who exercise regularly after long sit-a-thons at the office and aren't obese.

That's the sobering news from a new study that tracked more than 100,000 adults for 14 years. Researchers from the American Cancer Society in Atlanta followed 53,000 men and 70,000 women and asked them to fill out questionnaires about their physical activity.

Even after adjusting for body mass index (BMI) and smoking, the researchers found that women who sit more than 6 hours a day were 37 percent more likely to die than those who sit less than 3 hours; for men, long-sitters were 17 percent more likely to die.

'Biggest canal ever built by Romans' discovered

The Telegraph's Nick Squires reports:

One of the biggest canals ever built by the Romans in an ancient port as important as Carthage or Alexandria has been discovered by British archaeologists.

New saliva test 'can detect various cancers'

tpelia@yahoo.com (Tom Elia) — Wed, 30 Jun 2010 08:53:00 -0600

From Agence France-Presse:

Japanese and US universities have jointly developed a medical technique that can quickly detect various cancers using a simple saliva test, researchers said on Tuesday.

... the test detected 99 percent of pancreatic cancer cases, 95 percent of breast cancer and 80 percent of oral cancer cases among those taking part, [a statement released Monday by the researchers] said.

Cancer cells detected using $400 digital camera

tpelia@yahoo.com (Tom Elia) — Tue, 29 Jun 2010 11:45:50 -0600

From Gizmag:

Researchers have detected oral cancer cells using a fiber-optic cable and an off-the-shelf Olympus E-330 camera worth $400. The work by Rice University biomedical engineers and researchers from the University of Texas M.D. Anderson Cancer Center could improve access to diagnostic imaging tools in many parts of the world where these expensive resources are scarce.
...

"Consumer-grade cameras can serve as powerful platforms for diagnostic imaging," said Rice's Rebecca Richards-Kortum, the study's lead author. "Based on portability, performance and cost, you could make a case for using them both to lower health care costs in developed countries and to provide services that simply aren't available in resource-poor countries."

Co-authors of the paper include Dongsuk Shin and Mark Pierce, both of Rice, and Ann Gillenwater and Michelle Williams, both of the University of Texas M.D. Anderson Cancer Center. The research was funded by the National Institutes of Health.
