A UCLA team, headed by Brian Naranjo, has observed the nuclear fusion of deuterium nuclei in a tabletop device. The device uses a lithium tantalate (LiTaO₃) pyroelectric crystal to ionize deuterium atoms and accelerate the ions towards a stationary erbium deuteride (ErD) target. Fusion of two deuterium nuclei results in the emission of helium nuclei (alpha particles), neutrons and gamma rays. The team anticipates applications of the device as a tabletop neutron generator, or in “microthrusters” for space propulsion. It is possible that there may be applications related to nuclear weapons, although this possibility is not discussed in the research paper.

This development is not related to earlier claims of tabletop fusion or “cold fusion” having been observed during sonoluminescence. In fact, the leader of the team behind this development was one of the main critics of earlier low-temperature fusion claims.

This device is not the first reliable tabletop fusion device; the Farnsworth-Hirsch fusor, developed in the early 1960s in the laboratory of Philo T. Farnsworth who was instrumental in developing television, is sold commercially as a neutron source. Research by Dr. Todd Rider of MIT suggests that the kind of non-equilibrium fusion produced in these sources will never be usable as an energy source (see his PhD thesis).

On Saturday, Australian Prime Minister Scott Morrison announced the national government’s decision to recognise West Jerusalem as Israeli capital, while reaffirming the nation’s goal for two-state solution for Israel-Palestine conflict regarding authority of Jerusalem.

“The Australian government has decided that Australia now recognises West Jerusalem, as the seat of the Knesset and many of the institutions of government, is the capital of Israel”, Morrison said in a speech. Currently, the Australian embassy in Israel is situated in Tel Aviv.

Israel claims the entire city of Jerusalem to be its capital; while Palestine claims part, East Jerusalem, as its own territory and the capital of the proposed future state. Israel came to control East Jerusalem as part of the 1967 Arab-Israeli War. Jerusalem is considered a holy city by three major Abrahamic religions: Judaism, Christianity and Islam.

Spokesperson of the Israeli Embassy in Australia Eman Amasha issued a statement on Sunday saying “Israel views the decision of Australian Government to open its Trade and Defence Office in Jerusalem as a step in the right direction.”

Despite recognising West Jerusalem as Israeli capital, Morrison said the Australian Embassy would not be relocated to West Jerusalem until the Palestinian-Israeli conflict was resolved by a two-state solution. “We look forward to moving our embassy to West Jerusalem, when practical, in support of and after a final status determination […] We’ve decided to start the work there now, to identify a suitable site for an Australian embassy in West Jerusalem”, Morrison added. Morrison also said, “A two-state solution remains the only viable way to resolve the Israeli-Palestinian dispute”. Saeb Erekat, a senior Palestinian official, said, “The policies of this Australian administration have done nothing to advance the two-state solution”.

Senator Penny Wong of the opposition Labor Party in Australia said “Recognising West Jerusalem as Israel’s capital, while continuing to locate Australia’s embassy in Tel Aviv, is nothing more than a face-saving exercise that shows Mr Morrison continues to put self-interest ahead of the national interest. This is a decision which is all risk and no gain. It is a reckless move by a desperate and divided government that satisfies no one.” Another opposition leader Bill Shorten said he was worried the Prime Minister “put his political interest ahead of our national interest”.

Malaysia and Indonesia, two Muslim-majority neighbouring nations of Australia, responded to the decision.

The Foreign Ministry of Malaysia released a statement which read: “Malaysia strongly opposes the decision by the government of Australia to recognise West Jerusalem as the capital of Israel”. It went on to say: “Malaysia firmly believes that this announcement, made before the settlement of a two-state solution, is premature and a humiliation to the Palestinians and their struggle for the right to self-determination.”

Malaysia, which has been Australia’s free trade partner for almost six years now, emphasised on a two-state solution and concluded by saying “Malaysia will continue to work closely with all partners to find a just, comprehensive and lasting solution to the conflict.”

Speaking about Australian government’s announcement, Malaysian Prime Minister Mahathir Mohamad said, “Jerusalem has always been under Palestine, so why are they [Australia] taking the initiative to divide Jerusalem [as it is] not belonging to them, but to divide the Arabs and the Jews? They have no rights”.

The Indonesian Foreign Ministry’s statement said: “Indonesia calls on Australia and all member states of the UN [?United Nations?] to promptly recognise the State of Palestine and to co-operate towards the attainment of sustainable peace, and agreement between the state of Palestine and Israel based on the principle of two-state solution.”

Saeed Abu Ali, the Arab League’s Assistant Secretary General for Palestine and the Occupied Arab Territories, called Morrison’s decision “blatantly biased toward the positions and policies of the Israeli occupation.” Previously, in September, Saeed Abu Ali praised Paraguay’s decision to move its embassy back from Jerusalem to Tel Aviv as on the “right track”.

Last year, the United States, and Guatemala declared recognition of Jerusalem in its entirety as Israel’s capital. Paraguay followed the decision of the US and Guatemala, moving its embassy to Jerusalem, but, then-new President Mario Abdo Benítez reversed the decision. Paraguayan Foreign Minister Luis Luis Castiglioni said, “Paraguay wants to contribute to an intensification of regional diplomatic efforts to achieve a broad, fair and lasting peace in the Middle East”. Following Benítez’s decision, Israel announced closing its embassy in Paraguay and recalling its ambassador from Paraguay.

A compilation of brief news reports for Monday, May 7, 2007.

A 30 meter section of a gas pipeline in Luka (near Kiev) in Ukraine has been destroyed by an explosion. Although supplies to Europe via this pipeline have stopped, Ukrainian Energy Minister Georgi E. Boyko said that supplies to Europe would not be affected.

“There are no changes in volumes of gas being transported,” Yuri Korolchuk said. “Volumes due to pass through the damaged section are being redirected through the Soyuz pipeline.”

Normal flows are reported in the Czech Republic, Hungary, Poland and Romania.

Copper prices are rising. Between record copper imports from China, and a mining strike in Peru, the prices have climbed to over $8100 (United States dollars) a tonne, for a gain of $575 dollars over the last week. However the upward trend is not new, it has been climbing for quite some time. In April 2003, the price of copper was under $2000 a tonne.

The metal market has been tending up due to growth in the Chinese industrial production. This trickles down to the local level, where the buying price at scrap yards is ever climbing, making scrap metal collection a more profitable endeavour for individual people using pick up trucks or other such vehicles to collect and cash in the scrap metal at metal buying yards. It can be collected via agreements with businesses, from the garbage, or, sometimes, by theft.

Copper prices fell today on the NYMEX commodity exchange from US$3.7545 per pound to US$3.7125 based on the July futures contract.

One man was killed and another injured by an exploding backpack in the parking lot of the Luxor Hotel in Las Vegas, Nevada. The explosion happened at 4 a.m. PDT when the victim tried to remove a the object left on top of his car.

Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are on the scene. Aerial images did not show any apparent damage.

“We believe the victim was the intended target of this,” Bill Cassell said, spokesperson for the Las Vegas Metropolitan Police Department. “This is being treated as a homicide in which the weapon used to cause death is a non-traditional weapon.”

Both of the victims worked at the Luxor.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

The California Department of Justice on Wednesday released the warrant and affidavit of a criminal investigation of the Wells Fargo bank. The State of California served the warrant on October 5 to search the San Francisco headquarters of Wells Fargo for felonious activities related to identity theft.

The warrant said property to be seized at the bank’s San Francisco headquarters was related to the unauthorized creation of accounts by Wells Fargo employees including the names of individuals for the accounts; account information and fees; the names of employees and their managers who created accounts without the consent of the Wells Fargo customers in question; and all communications including emails referencing the unauthorised accounts.

California Attorney General Kamala Harris’s criminal probe is part of an increasing list of officials nationwide questioning the business practices of Wells Fargo such as California State Treasurer John Chiang who announced a one-year suspension of State investment with the bank on September 28; Illinois State Treasurer Mike Frerichs followed suit with a year-long ban on October 3; and Democratic United States Senators Bob Menendez of New Jersey, Jeff Merkley of Oregon, and Elizabeth Warren of Massachusetts, who wrote to the U.S. Security Exchanges Commission (SEC) suggesting investigation on September 29.
