The thought process behind is potentially a bit of both. There is some pretty convincing evidence that for a lot of indications that any benefit is almost surely placebo effect. There is another line of thinking that there may be a small amount of benefit from pressure point therapy. There is another thought process that what accupuncture is doing is relieving muscle cramp and that subjective benefit is appropriated to the actual underlying condition. It's sort of an effect where you have gastroenteritis and are nauseous and vomiting. You develop a headache from all of the wretching and I give you a Tylenol. It makes your headache better and now you perceive that over overall illness is also better. The Tylenol did absolutely nothing to resolve your nausea, vomiting and diarrhea but you subjectively feel better and therefore attribute that the Tylenol helps you.
When I get into discussions on alternative treatments I really leave it up to a if you have the money AND you feel like it gives you benefit AND I know that it isn't actually causing harm (like telling someone to stop chemo and take cesium and potassium supplements at an exhorbitant personal cost to treat lung cancer).

A good summary of an argument against acupuncture actually doing anything:

and a huge collection of resources on why it doesn't work:

It's especially amazing when you realize how recent these feats are in human history. We've barely had functioning airplanes for a century and now we have a robot doing lab work for us on Mars, probes landing on comets, and a permanently manned space station. Blows my mind.
It's too bad New Horizons can't also swing by Eris (and its moon), but I guess it's pretty far out of its way, on the other side of the system, and won't be back for another couple centuries or so. Hurry home, Eris, I don't think I'm going to make it to 2250.

Helium found leaking in the Newport-Inglewood fault mantle, far more than that found in the San Andreas fault:
A huge fault in the Earth's crust near Los Angeles is leaking helium, researchers have found.
They say the unexpected find sheds new light on the Newport-Inglewood Fault Zone in the Los Angeles Basin.
It reveals the fault is far deeper than previously thought, and a quake would be far more devastating.
UC Santa Barbara geologist Jim Boles found evidence of helium leakage from the Earth's mantle along a 30-mile stretch of the Newport-Inglewood Fault Zone in the Los Angeles Basin.
He claims the results show that the Newport-Inglewood fault is deeper than scientists previously thought.
...Boles discovered that more than one-third of the sites show evidence of high levels of helium-3 (3He).
'The results are unexpected for the area, because the LA Basin is different from where most mantle helium anomalies occur,' said Boles, professor emeritus in UCSB's Department of Earth Science.
'The Newport-Inglewood fault appears to sit on a 30-million-year-old subduction zone, so it is surprising that it maintains a significant pathway through the crust.'
...they found that high levels of 3He inversely correlate with carbon dioxide (CO2), which Boles noted acts as a carrier gas for 3He.
An analysis showed that the CO2 was also from the mantle, confirming leakage from deep inside the Earth.
'This paper shows that the mantle is leaking more at the Newport-Inglewood fault zone than at the San Andreas Fault, which is a new discovery.'
'We show that the Newport-Inglewood fault is not only deep-seated but also directly or indirectly connected with the mantle,' Boles said.
'We are fortunate that seismic activity in California has been relatively low over the past century,' said Tom Jordan, Director of the Southern California Earthquake Center and a co-author of the study.
'But we know that tectonic forces are continually tightening the springs of the San Andreas fault system, making big quakes inevitable.
...the estimate for the likelihood that California will experience a magnitude 8 or larger earthquake in the next 30 years has increased from about 4.7% for UCERF2 to about 7.0% for UCERF3.
The UCERF3 model is of the first kind, and is the latest earthquake-rupture forecast for California. It was developed and reviewed by dozens of leading scientific experts from the fields of seismology, geology, geodesy, paleoseismology, earthquake physics and earthquake engineering.

The Universe "is slowly dying." (Don't worry it's not the end of the world),
Goodbye, universe. You came in with the biggest bang ever, but now, you're on your way out with a drooping fizzle.
The conclusion of a new astronomical study pulls no punches on this. "The Universe is slowly dying," it reads.
Astronomers have believed as much for years, but the new findings establish the cosmos' decline with unprecedented precision.
An international team of some 100 scientists used data from the world's most powerful telescopes -- based on land and in space -- to study energy coming from more than 200,000 galaxies in a large sliver of the observable universe.
Based on those observations, they have confirmed the cosmos is radiating only half as much energy as it was 2 billion years ago. The astronomers published their study on Monday on the website of the European Southern Observatory.

read this article today about current consumption rates and how the world has consumed the yearly production of the earth by august 15. it raises some very worrying thoughts about what the future may bring. i just dont see people sitting idly starving to death. can governments actually develop a unified direction on how to get the worlds population under control. obviously there are alot of variables and its complex. what sacrifices are going to be made. i think doing nothing is the worst idea but not sure what direction we should be taking. that said the last 20 years has been frustration as we know there is a problem but there's been alot of denial about the situation. i dont want to see a genocide type of answer to this problem but if i have thought it people with alot less moral reservation have been thinking about it too

This problems could be rectified if Nations shifted there focus and money from Military endavours to saving the planet. Hopefully the time will come. It might take some very scary things to happen first but we will get there.

It's science sort of, but I'm looking forward to the robot battle between the US company Megabots and the Japanese Kurata robot.

Does smoking shorten lifespans? Yes and no...according to a study that appeared in The Journals of Gerontology, Biological and Medical Sciences:
Not all smokers experience early mortality, however, and a small proportion manage to survive to extreme ages.
Using long-lived smokers as their phenotype, the authors identified a network of SNPs (a DNA sequence variation occurring commonly within a population) that allow certain individuals to better withstand environmental damage (like smoking) and mitigate damage. Collectively, these SNPs were strongly associated with high survival rates.
...they identified a set of genetic markers that together seem to promote longevity and many of these markers are in pathways that were discovered to be important for aging and lifespan in animal models.
...there is evidence that these genes may facilitate lifespan extension by increasing cellular maintenance and repair.
Therefore, even though some individuals are exposed to high levels of biological stressors, like those found in cigarette smoke, their bodies may be better set up to cope with and repair the damage.
These findings suggest that longevity, rather than being entirely determined by environmental factors, may be under the regulation of complex genetic networks which influence stress resistance and genomic stability.

Red moon rising...get ready for a "Supermoon":
It won't happen again until 2033. Starting late tonight and lasting approximately 72 minutes, a Supermodn will be in effect -- that is, when a total lunar eclipse takes effect and the moon appears red -- due to it's close proximity to earth.

Sonic Tractor Beams Are Now A Reality
Researchers from the Universities of Bristol and Sussex, England in collaboration with Ultrahaptics have developed the first sonic tractor beam that can lift and move objects using nothing but sound waves.
The team used a system made of 64 miniature loudspeakers able to create high-pitched and high-intensity sound waves, generating an acoustic hologram that can lift, move, rotate and hold small objects. The system can create three different shapes of acoustic force fields. The first was made to resemble tweezers, the second was a vortex-like structure which trapped the object in the middle, and the last one surrounds the object from all directions and keeps it in place.
This new technology presents the opportunity for far-reaching applications: from mechanical support moving and assembling delicate objects, to medical aid where miniaturized beams could guide drugs through living tissue.

That one sounds both amazing and advanced. God knows how much this will help in that category alone medical-wise, but nevertheless it will eventually be an incredible breakthrough.
