The Science of Kissing COVER! | The Intersection

So what do you think?! The Science of Kissing will be out next January and is already available for pre-order on Amazon. Here's the description: From a noted science journalist comes a wonderfully witty and fascinating exploration of how and why we kiss. When did humans begin to kiss? Why is kissing integral to some cultures and alien to others? Do good kissers make the best lovers? And is that expensive lip-plumping gloss worth it? Sheril Kirshenbaum, a biologist and science journalist, tackles these questions and more in THE SCIENCE OF KISSING. It's everything you always wanted to know about kissing but either haven't asked, couldn't find out, or didn't realize you should understand. The book is informed by the latest studies and theories, but Kirshenbaum's engaging voice gives the information a light touch. Topics range from the kind of kissing men like to do (as distinct from women) to what animals can teach us about the kiss to whether or not the true art of kissing was lost sometime in the Dark Ages. Drawing upon classical history, evolutionary biology, psychology, popular culture, and more, Kirshenbaum's winning book will appeal to romantics and armchair scientists alike.

Topography Reflects Baja Quake Site’s Complex Geology

Topography surrounding the Laguna Salada Fault
The site of an April 4, 2010, magnitude 7.2 earthquake, the Laguna Salada fault in Baja, California, is clearly shown in this image from NASA's Shuttle Radar Topography Mission.
› Full image and caption

The topography surrounding the Laguna Salada fault in the Mexican state of Baja, California, is clearly shown in this combined radar image and topographic view (above) generated with data from NASA's Shuttle Radar Topography Mission (SRTM). On April 4, 2010, a magnitude 7.2 earthquake struck along this fault about 64 kilometers (40 miles) south of the Mexico-United States border.

According to the U.S. Geological Survey, the earthquake was the largest to strike this area since 1892. This fault is a probable southern continuation of the Elsinore fault zone in Southern California, and is related to the San Andreas fault zone complex. Aftershocks since the major event have appeared to extend in both directions along this fault system from the epicenter, marked by the red star.

This view combines a radar image acquired in February 2000 during SRTM, and color-coding by topographic height using data from the mission's data. Dark green colors indicate low elevations, rising through lime green, yellow and tan, to white at the highest elevations. The image shows a simulated view toward the southwest, with the topography exaggerated by a factor of two for clarity.

NASA Demonstrates Ocean-Powered Underwater Vehicle

NASA, U.S. Navy and university researchers have successfully demonstrated the first robotic underwater vehicle to be powered entirely by natural, renewable, ocean thermal energy.

The Sounding Oceanographic Lagrangrian Observer Thermal RECharging (SOLO-TREC) autonomous underwater vehicle uses a novel thermal recharging engine powered by the natural temperature differences found at different ocean depths. Scalable for use on most robotic oceanographic vehicles, this technology breakthrough could usher in a new generation of autonomous underwater vehicles capable of virtually indefinite ocean monitoring for climate and marine animal studies, exploration and surveillance.

Researchers at NASA's Jet Propulsion Laboratory, Pasadena, Calif.; and the Scripps Institution of Oceanography, University of California, San Diego, completed the first three months of an ocean endurance test of the prototype vehicle off the coast of Hawaii in March.

"People have long dreamed of a machine that produces more energy than it consumes and runs indefinitely," said Jack Jones, a JPL principal engineer and SOLO-TREC co-principal investigator. "While not a true perpetual motion machine, since we actually consume some environmental energy, the prototype system demonstrated by JPL and its partners can continuously monitor the ocean without a limit on its lifetime imposed by energy supply."

"Most of Earth is covered by ocean, yet we know less about the ocean than we do about the surface of some planets," said Yi Chao, a JPL principal scientist and SOLO-TREC principal investigator. "This technology to harvest energy from the ocean will have huge implications for how we can measure and monitor the ocean and its influence on climate."

SOLO-TREC draws upon the ocean's thermal energy as it alternately encounters warm surface water and colder conditions at depth. Key to its operation are the carefully selected waxy substances known as phase-change materials that are contained in 10 external tubes, which house enough material to allow net power generation. As the float surfaces and encounters warm temperatures, the material melts and expands; when it dives and enters cooler waters, the material solidifies and contracts. The expansion of the wax pressurizes oil stored inside the float. This oil periodically drives a hydraulic motor that generates electricity and recharges the vehicle's batteries. Energy from the rechargeable batteries powers the float's hydraulic system, which changes the float's volume (and hence buoyancy), allowing it to move vertically.

So far, SOLO-TREC has completed more than 300 dives from the ocean surface to a depth of 500 meters (1,640 feet). Its thermal recharging engine produced about 1.7 watt-hours, or 6,100 joules, of energy per dive, enough electricity to operate the vehicle's science instruments, GPS receiver, communications device and buoyancy-control pump.

The SOLO-TREC demonstration culminates five years of research and technology development by JPL and Scripps and is funded by the Office of Naval Research. JPL developed the thermal recharging engine, building on the buoyancy engine developed for the Slocum glider by Teledyne Webb Research, Falmouth, Mass. Scripps redesigned the SOLO profiling float and performed the integration. The 84-kilogram (183-pound) SOLO-TREC prototype was tested and deployed by the JPL/Scripps team on Nov. 30, 2009, about 161 kilometers (100 miles) southwest of Honolulu.

The performance of underwater robotic vehicles has traditionally been limited by power considerations. "Energy harvesting from the natural environment opens the door for a tremendous expansion in the use of autonomous systems for naval and civilian applications," said Thomas Swean, the Office of Naval Research program manager for SOLO-TREC. "This is particularly true for systems that spend most of their time submerged below the sea surface, where mechanisms for converting energy are not as readily available. The JPL/Scripps concept is unique in that its stored energy gets renewed naturally as the platform traverses ocean thermal gradients, so, in theory, the system has unlimited range and endurance. This is a very significant advance."

SOLO-TREC is now in an extended mission. The JPL/Scripps team plans to operate SOLO-TREC for many more months, if not years. "The present thermal engine shows the great promise in harvesting ocean thermal energy," said Russ Davis, a Scripps oceanographer. "With further engineering refinement, SOLO-TREC has the potential to augment ocean monitoring currently done by the 3,200 battery-powered Argo floats." The international Argo array, supported in part by the National Oceanic and Atmospheric Administration, measures temperature, salinity and velocity across the world's ocean. NASA and the U.S. Navy also plan to apply this thermal recharging technology to the next generation of submersible vehicles.

Juno Taking Shape in Denver

Juno during assembly
Workers move into place the vault that will protect Juno's sensitive electronics from Jupiter's intense radiation belts.
Assembly has begun on NASA's Juno spacecraft, which will help scientists understand the origin and evolution of Jupiter. The mission, whose principal investigator is Scott Bolton of Southwest Research Institute in San Antonio, Tex., is expected to launch in August 2011 and reach Jupiter in 2016.

The assembly, testing and launch operations phase began April 1 in a high-bay clean room at Lockheed Martin Space Systems in Denver. Engineers and technicians will spend the next few months fitting instruments and navigation equipment onto the spacecraft.

"We're excited the puzzle pieces are coming together," Bolton said. "We're one important step closer to getting to Jupiter."

Jupiter is the largest planet in our solar system. Underneath its dense cloud cover, the planet safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars.

Juno will have nine science instruments on board to investigate the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras.

"We plan to be doing a lot of testing in the next few months," said Jan Chodas, the project manager based at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "We want to make sure the spacecraft is ready for the long journey to Jupiter and the harsh environment it will encounter there."

JPL manages the Juno mission for the principal investigator, Scott Bolton. Lockheed Martin Space Systems is building the spacecraft. The Italian Space Agency, Rome, is contributing an infrared spectrometer instrument and a portion of the radio science experiment.

Ofquack to regulate herbal medicine?

The attempted regulation of herbalism looks doomed to failure with a clear difference of opinion between government and practitioners, the latter prefer statutory regulation which has been rejected as an option by government.

Last week the Department of Health (DoH) recommended that the Complementary and Natural Healthcare Council (CNHC/Ofquack)  regulate herbal medicine, traditional Chinese medicine (TCM) and acupuncture.  Minister for Health, Andy Burnham, said:

“Emerging evidence clearly demonstrates that the public needs better protection, but in a way that is measured and does not place unreasonable extra burdens on practitioners.

“I am therefore minded to legislate to ensure that all practitioners supplying unlicensed herbal medicines to members of the public in England must be registered with the Complementary and Natural Healthcare Council (CNHC).

The CNHC have expressed their pleasure at this announcement:

CNHC is pleased to be asked by The Secretary of State for Health to register practitioners supplying herbal medicines to members of the public in England.

The Council already registers a significant range of practitioners in complementary healthcare who meet its standards and is well positioned to expand its public protection role in this way. Since 2008 CNHC has established its reputation as a regulatory body with robust and effective standards for registration and fitness to practise. It has positive and collaborative links with the statutory healthcare regulators.

This is probably regarded as good news by the CNHC, they have had a well documented struggle for funding and have trouble attracting some of the more popular forms of quackery.   Regardless of this, the CNHC are not fit for purpose, they have recently told sceptical blogger Simon Perry that they will not consider his complaints for the next 6 months:

I began making complaints to the Complementary and Natural Healthcare Council about reflexologist members who happily promote their bogus treatments despite the fact that there was not a jot of evidence to support them.

The CNHC has now informed me that for the next six months, they will no longer be processing any complaints that are similar to the ones I’ve submitted. By similar, I take this to mean complaints regarding practitioners who mislead their clients by making unjustifiable or false statements, including practitioners who have already been cautioned by the CNHC for doing it before.

The CNHC was set up under the aegis of Prince Charles’ Foundation for Integrated Health (FIH) to be a self-regulatory body for alternative health, now it is one that is not prepared to regulate.  However this is not unexpected.  Organisations purporting to regulate quackery rarely do so beyond upholding the doctrines and articles of faith of the respective field of quackery, managing risks to consumer health are generally not a priority.

It would be a concern for those with an interest in exposing the practices of alternative medicine if the CNHC were to regulate herbal medicine, traditional Chinese medicine and acupuncture.  This, despite the recommendations of Andy Burnham, is unlikely to happen for two reasons.

1) The government is unlikely to exist in its current form within a month or two.  A general election is expected early in May and the Labour party are unlikely to win, if they are to remain in power it will be in a coalition but it is more likely that the next government will be formed from the Conservative party.  None of the major parties have a clearly stated policy on the regulation of alternative medicine, nor is it likely to be a major election issue, so the Department of Health’s current proposals are likely to be mothballed for some considerable time.

2) Herbalists  and TCM practitioners do not want CNHC regulation.

This latter point is the most important.  The European Herbal & Traditional Medicine Practitioners Association (EHTMPA), the Register of Chinese Herbal Medicine (RCHM), the Association of Traditional Chinese Medicine (ATCM), and the National Institute of Medical Herbalists (NIMH) amongst others in the alphabetical smorgasbord that represents the various denominations of herbalism, have all campaigned for statutory regulation.  Their intent was to be regulated by the Health Professionals Council (HPC), a more serious organisation than the CNHC, that regulates practitioners in proven fields of health.  This statutory regulation would confer protected status on their profession, restricting the title of Herbalist to those regulated by its rules.

By and large these organisations are disappointed with the DoH’s announcement:

the CNHC (the proposed regulator) was formed to regulate complementary health practitioners on a voluntary basis, and as currently constituted, is not equipped for statutory regulation.

the government seems to have failed to deliver its promise, and has changed its mind from HPC as our regulatory body to CNHC. We would like to demand an explanation from the government on what ground it has changed its mind, as CNHC is only a voluntary body with no statutory power. From the rather short DH press release which lacks details, we doubt whether the government still wants to introduce statutory regulation, or decides to go for an alternative.

Herbalists should be regulated like other statutory regulated healthcare practitioner or, the public will lose access to properly regulated herbalists and a wide range of herbal medicines. The Government must give detailed assurances that the legal and structural basis of statutory regulation is fit for purpose or it will betray the millions of people who regularly consult herbal practitioners. So far the Government has singularly failed to provide these guarantees.

As the CNHC is voluntary these organisations have no need to insist that their members sign up, in fact as they are holding out for statutory regulation it is unlikely that they will be willing to express any support for the CNHC, to do so would undermine their campaign.  This will damage the CNHC’s longterm viability, no new members means no new funding sources, and with the homeopaths mired in infighting the herbalists represent their last decent chance of acquiring new members in the medium term.

This is good news for those that are concerned about poor practice in alternative medicine.  The collapse of the CNHC will further damage the reputation of alternative medicine.  Hopefully a new government will take stock of the intransigence of the herbalists, the infighting of the homeopaths and the inability of the CNHC to regulate and instead apply a more robust external form of regulation for quackery.
