United States President George W. Bush addressed the nation on the economic financial crisis from inside the White House saying the economic situation is “serious” and is “in danger” of becoming “a long and painful recession.”

“We are in the midst of a serious financial crisis and the federal government is responding with decisive action,” Bush said in his televised speech.

Bush called for the United States Congress to pass a US$700 billion bill intended to keep struggling companies afloat. He asked the two presidential candidates along with leaders from both parties of Congress to join him for a conference on Thursday.

Last Friday, Treasury Secretary Henry Paulson called for a bailout plan that would allow for the United States government to purchase devalued mortgage backed securities, resulting from the subprime mortgage crisis, from troubled financial institutions. Paulson has said that the plan could cost up to $700 billion. Congressional leaders have said that some form of the plan will pass; however, there is considerable debate over several key issues.

White House spokeswoman Dana Perino said that Bush “believes it is important for the American people to fully understand the depth of the crisis in our financial markets, how that crisis affects them, and the urgent need to agree on a solution.” Bush has been criticized for waiting too long to speak in prime time.

John McCain suspended his campaign to return to Washington and work on the bailout bill. Barack Obama has called for another form of the bill to pass and said that Congress should not package the bailout bill with any other bills — such as an economic stimulus plan.

Meanwhile, Congress has held a second round of hearings on the proposed bailout bill. Paulson and Chairman of the Federal Reserve Ben Bernanke testified in front of the House Financial Services Committee. They felt it was a serious problem in need of an immediate solution.

Rep. Barney Frank, Chairman of House Financial Services Committee, says it is “clear” that the financial bailout bill will pass.

Director of the Congressional Budget Office Peter R. Orsza said while testifying before Congress that “ironically, the intervention could even trigger additional failures of large institutions, because some institutions may be carrying troubled assets on their books at inflated values.”

The bailout plan has been called a “blank check” by many, with members of both parties divided on the issue.

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.

On Tuesday representatives from US-based online retailer Amazon.com and smart doorbell company Ring announced the startup company will be acquired by Amazon. Ring builds WiFi-connected video doorbells that allow homeowners to view and talk to people at their door from their smartphone. Ring also sells security cameras.

The deal was not officially announced to have happened, although an Amazon spokesperson told about the acquisition to US television channel CNBC (Consumer News and Business Channel).

Analysts suggested the deal could aid the Amazon Key service, which allows Amazon grocery, and other, deliveries to be dropped off inside Amazon Prime members’ homes. Use of Ring WiFi-connected cameras would complement the indoor Cloud Cam Amazon provides to members.

Previously, Ring’s CEO, Jamie Siminoff, remarked the company started when his doorbell wasn’t audible from his shop in his garage. He built a WiFi door bell, he said. Siminoff said sales boosted after his 2013 appearance in a Shark Tank episode where the show panel declined funding the startup. In late 2017, Siminoff appeared on shopping television channel QVC. Ring also settled a lawsuit with competing security company, the ADT Corporation.

Amazon’s Echo smart home speaker product had already been integrated with Ring, by taking voice commands to show the image from a Ring front door camera on an Echo Show device. Amazon had also purchased Blink, a manufacturer of internet-connected security cameras and doorbells, in late 2017.

A rooftop protest at a Devon (UK) jail has ended peacefully after almost 28 hours.

The protest, involving 10 inmates, at HMP Channings Wood started after prisoners complained their meals were being prepared by sex offenders.

The category C training prison in Newton Abbot, Devon presently holds 663 inmates, with units dedicated to sex offenders and drug offenders.

A Home Office spokesman said: “The rooftop protest at HMP Channings Wood has ended peacefully with no injuries to prisoners or prison staff.”

The Prison Service has so far refused to confirm the extent of the damage done during the protest, but it is believed to run into thousands of pounds with glass being smashed and paving slabs being torn up.

Earlier on Monday afternoon three prisoners had already given up their protest, leaving ten remaining on the roof. They eventually came down at around 6:30 p.m. BST after speaking with trained negotiators.

The Prison Service has launched an internal enquiry into the protest.

A World Health Organisation study published in The Lancet has revealed the main causes of death for people aged 10–24. It has described the majority of these deaths as preventable and suggested solutions to the problems.

97% of the 2.6 million fatalities annually occur in low- and middle-income countries. The age group comprises 1.8 billion people, 30% of the total population. 15% of female deaths were down to “maternal mortality” which included pregnancy complications, unsafe abortions, and mutilation of genitals. Road traffic accidents accounted for 10% of deaths.

6.3% of the deaths were suicides and 6% were down to violence. Tuberculosis and similar lung infections took 10% of the lives and HIV/AIDS killed 5.5%. Most of the deaths were in sub-Saharan Africa and Southeast Asia. Africa and Southeast Asia were also the only places where male deaths were not above those of females, as much of the maternal mortality occurred there. The data came from 2004.

In developed countries, 32% of the deaths were down to road accidents. “There has long been an assumption that young people are healthy, fit and they don’t die,” explained the report’s lead author, Australian children’s health expert George Patton. He goes on to say “I’ve certainly heard politicians and policy-makers make statements of that kind… Some of these problems, related to emotion, are actually very prominent causes not only of death in adolescence, but health problems later in life.”

The study said safer speed limits, more use of helmets and seatbelts, and better enforcement of drunk driving law could greatly curb the road deaths. Maternal deaths and sexually transmitted disease rates could be cut by sexual education, safe abortion clinics, pregnancy support, HIV testing and treatment, and access to contraceptives.

Violence and suicide could be reduced by education in life skills and an improved role of parents, the study found. It also sought reduction of availability of poisons, firearms, and other dangerous items. In the case of suicide, the study said more work was needed to help young people recover from acts of violence, sexual assault, and child abuse in both the short and long term. Alcohol access reduction was also requested.

The study was conducted by University College London’s Russell Viner, World Health Organization’s Krishna Bose and George Patton of the Royal Children’s Hospital in Melbourne, Australia.
