From Time Magazine:

Disciplining young children is one of the key jobs of any parent — most people would have no trouble agreeing with that. But whether or not that discipline should include spanking or other forms of corporal punishment is a far trickier issue.

The American Academy of Pediatrics (AAP) does not endorse spanking for any reason, citing its lack of long-term effectiveness as a behavior-changing tactic. Instead the AAP supports strategies such as time-outs when children misbehave, which focus on getting kids to reflect on their behavior and the consequences of their actions. Still, as many parents can attest, few responses bring about the immediate interruption of a full-blown tantrum like a swift whack to the bottom.

Take From ATM Malware Caper Exceeded $200,000

From Threat Level:

A Bank of America worker who installed malicious software on his employer’s ATMs was able to siphon at least $200,000 from the hacked machines before he was caught, according to a plea agreement he entered with prosecutors last week.

Rodney Reed Caverly, 37, was a member of the bank’s IT staff when he installed the malware, which instructed the machines to dispense free cash without creating a record of the transaction. The Charlotte, North Carolina, man made fraudulent withdrawals over a seven-month period ending in October 2009, according to prosecutors, who’ve charged him with one count of computer fraud.

From Discovery News:

Twenty major U.S. streams and rivers have warmed significantly over the last few decades, according to new research.

Along with warmer air and warmer oceans, rivers also seem to be heating up with global warming. Across the United States, a new study found, water temperatures in some rivers have risen by more than 3 degrees Celsius in the last few decades.

From Science Daily:

ScienceDaily (Apr. 11, 2010) — Underwater canyons have long been considered important habitats for marine life, but until recently, only canyons on continental margins had been intensively studied. Researchers from Hawaii Pacific University (HPU) and the Universtiy of Hawaii at Manoa (UHM) have now conducted the first extensive study of canyons in the oceanic Hawaiian Archipelago and found that these submarine canyons support especially abundant and unique communities of megafauna (large animals such as fish, shrimp, crabs, sea cucumbers, and sea urchins) including 41 species not observed in other habitats in the Hawaiian Islands.

Town From Before Invention Of Wheel Revealed

From Live Science:

A prehistoric town that had remained untouched beneath the ground near Syria for 6,000 years is now revealing clues about the first cities in the Middle East prior to the invention of the wheel.

The town, called Tell Zeidan, dates from between 6000 B.C. and 4000 B.C., and immediately preceded the world's first urban civilizations in the ancient Middle East. It is one of the largest sites of the Ubaid culture in northern Mesopotamia.

Gorillas Losing Battle Against Loggers And Hunters In Central Africa

From Times Online:

Gorillas in Central Africa are in danger from illegal logging, mining and from hunters killing great apes for meat, says a new report from the United Nations and Interpol.

In 2002 it was estimated that only 10 per cent of gorillas would remain by 2030.

“We fear now that the gorillas may become extinct from most parts of their range in perhaps 15 years,” said Christian Nellemann, of the UN Environmental Programme.

From The Telegraph:

Three species of creature, which are only a millimetre long and resemble jellyfish encased in shells, were found 2.2 miles (3.5km) underwater on the ocean floor, 124 miles (200km) off the coast of Crete, in an area with almost no oxygen.

The animals, named Loriciferans due to their protective layer, or lorica, were discovered by a team led by Roberto Danovaro from Marche Polytechnic University in Ancona, Italy.

How Carbon Dioxide In The Blood Could Be Responsible For Near-Death Experiences

Towards the light: People who have out-of-body experiences on the operating table may have high levels of carbon dioxide in their blood

From The Daily Mail:

Some experience an out-of-body floating sensation, others an intense feeling of joy and peace.

Now scientists believe they have explained what causes the near death experiences reported by thousands of people on the operating table.

A study of heart attack victims has found a link between out of body experiences and high levels of carbon dioxide in the blood.

Wonder Lust: Trinity Test Site

Making the pilgrimage to ground zero (Image: Joe Raedle/Getty)

From New Scientist:

AT 15 seconds to 5.30 am on 16 July 1945, the world's first nuclear explosion turned 4 hectares of sand into glass and signalled the start of the atomic age. It happened at the Trinity site in the Jornada del Muerto desert of southern New Mexico.

It's hard to imagine a more isolated, desolate spot. Yet the site, part of the White Sands missile range, is open two days each year to pilgrims to this "ground zero" of the nuclear arms race. Aside from a bus that runs between the blast site and a historic ranch house where the bomb's plutonium core was assembled, visitors have to fend for themselves.

Hewlett Packard Outlines Computer Memory Of The Future

Image: 17 memristors captured by an atomic force microscope

From The BBC:

The fundamental building blocks of all computing devices could be about to undergo a dramatic change that would allow faster, more efficient machines.

Researchers at computer firm Hewlett Packard (HP) have shown off working devices built using memristors - often described as electronics' missing link.

These tiny devices were proposed 40 years ago but only fabricated in 2008.

HP says it has now shown that they can be used to crunch data, meaning they could be used to build advanced chips.

That means they could begin to replace transistors - the tiny switches used to build today's chips.

Periodic Discussions: It's Going To Take A Long Time For Element 117 To Make It Onto The Periodic Table. Why?

From Slate:

A team of Russian and American scientists announced today the creation of several atoms of the previously unknown element 117. The discovery of "ununseptium" will eventually fill a longtime gap on the periodic table, although that formal change may not happen for years. In June 2009, element 112 was designated as an official element, more than a decade after it was first created. Sam Kean explained why changing the periodic table requires the scientific equivalent of a Supreme Court decision. His column is reprinted below.

ScienceDaily (Apr. 10, 2010) — "Supervolcanoes" have been blamed for multiple mass extinctions in Earth's history, but the cause of their massive eruptions is unknown.

Despite their global impact, the eruptions' origin and triggering mechanisms have remained unexplained. New data obtained during a recent Integrated Ocean Drilling Program (IODP) expedition in the Pacific Ocean may provide clues to unlocking this mystery.

From Live Science:

A shrunken brain may potentially lie inside the fossil skull of a newfound candidate for the immediate ancestor to the human lineage, researchers now reveal.

This new species, dubbed Australopithecus sediba, was accidentally discovered in South Africa by the 9-year-old son of a scientist. Two members of this hominid were introduced to the world last week — a juvenile male and an adult female, who might have known each other in life and who could have met their demise by falling into the remains of the cave where they were discovered.

The 10 Best Mathematicians

From The Guardian:

Alex Bellos selects the maths geniuses whose revolutionary discoveries changed our world.

Pythagoras (circa 570-495BC)

Vegetarian mystical leader and number-obsessive, he owes his standing as the most famous name in maths due to a theorem about right-angled triangles, although it now appears it probably predated him. He lived in a community where numbers were venerated as much for their spiritual qualities as for their mathematical ones. His elevation of numbers as the essence of the world made him the towering primogenitor of Greek mathematics, essentially the beginning of mathematics as we know it now. And, famously, he didn't eat beans.
