Experts Solve Mystery of Unpopped Popcorn

By RICK CALLAHAN, Associated Press Writer

INDIANAPOLIS - Eat your way to the bottom of almost any bag of popcorn and there they are: the rock-hard, jaw-rattling unpopped kernels known as old maids. The nuisance kernels have kept many a dentist busy, but their days could be numbered: Scientists say they now know why some popcorn kernels resist popping into puffy white globes.
It's long been known that popcorn kernels must have a precise moisture level in their starchy center — about 15 percent — to explode. But Purdue University researchers found the key to a kernel's explosive success lies in the composition of its hull.
It turns out there is an optimal hull structure that allows kernels to explode, and leaky hulls prevent the moisture pressure buildup needed for kernels to pop.
"They're sort of like little pressure vessels that explode when the pressure reaches a certain point," said Bruce Hamaker, a Purdue professor of food chemistry. "But if too much moisture escapes, it loses its ability to pop and just sits there."
He and his associates compared the microwave popping performance of 14 Indiana-grown popcorn varieties and examined the crystalline structure of the translucent hulls of both the popped kernels and the duds.
In the varieties popped, the percentage of unpopped kernels ranged from 4 percent in premium brands to 47 percent in the cheaper ones.

When One World Isn't Enough
By Staff, TheWorld.ae
Al Nakheel Properties reportedly has begun construction on a conglomeration of more than 200 man-made, private islands off the coast of Dubai. The set-up imitates earth's continental arrangement and will become a sort of Disney World Epcot center for the affluent elite, with the islands themed according to the countries they represent.

Monica Seles - (b. in the Vajdaság (Vojvodina), the Hungarian region that was given to Serbia/Yugoslavia.)
Tennis Superstar - She has won 9 Grand Slam singles titles and bronze in Sydney 2000!
Seles (pronounced sell-esh and spelled Szeles Monika) won the European junior championship at the age of ten. Born to a Hungarian family in the former Hungarian province of Vojvodina, she moved to the United States in 1986, and in 1989 turned professional. In 1990 she won her first French Open, and in each of the following two years she won the Australian, United States, and French opens. Seles won the Australian Open in early 1993, but later that year, while resting between sets during a tournament in Hamburg, Germany, she was stabbed by a spectator. The incident caused Seles to withdraw from competition in 1993 and 1994. Seles returned to competition in 1995 and won the initial tournament of her comeback, the Canadian Open. In 1996 she again won the Australian Open.

Monica is a fierce competitor and is still going strong into the new millennium including winning the Bronze medal at the 2000 Sydney Olympics!

Local derby ends in farcical 62-0 scoreline

BELGRADE: A local derby in the community of Bistrica near Pozarevac in Serbia and Montenegro ended in a 62-0 victory for one club after their opponents were instructed not to provide any opposition, Serbian media reported yesterday.

The two unnamed clubs were involved in a close derby, when the president of one of the teams decided to instruct his players in the 13th minute to stay on the field but not try to prevent the other side from scoring to protest against earlier refereeing decisions.

The half-time score was 22-0, but the side added a further 40 goals in the second half, with even the goalkeeper scoring five times.
The local football association have suspended all the players involved and said that the action was "unsporting". They are to take a final decision on Tuesday.

Rhinoplasty

Rhinoplasty is considered to be one of the most gratifying plastic surgeries to receive, because the patient often will find their entire facial aesthetic modified.
Surgery

-- Before
The night before surgery, do not eat or drink after midnight. Arrive early, because you may have to give blood for lab analysis or have to complete extra paperwork.
-- During
The whole operation takes anywhere from two to four hours, depending on the complexity. It can be performed under local anesthesia, with IV sedation, or under general anesthesia. Before any incision is made, the nose is numbed with local anesthesia (usually lidocaine or marcaine with epinephrine). In addition, a combination of cocaine and/or epinephrine, because it helps to shrink the mucous membranes and control bleeding.
Throughtout the operation, the surgeon will frequently check the patient's profile, the symmetry of the tip, and the improvement after each small change is made. Even small changes consisting of one to two and up to four millimeters can make large changes in the overall appearance of the nose.
At the end of the surgery, the doctor will recheck the size of the nostril. If the nostril base is wide, they will be made smaller. Finally, the nose is packed and kept that way for seven to ten days. Pain medicine and antibiotics are prescribed.

Nuclear fusion on the desktop ... really!
Mini-reactor yields neutrons, could power spacecraft

MSNBC staff and news service reports
Updated: 2:56 p.m. ET April 27, 2005


Scientists say they have achieved small-scale nuclear fusion in a tabletop experiment, using tried and true techniques that are expected to generate far less controversy than past such claims.

This latest experiment relied on a tiny crystal to generate a strong electric field. While the energy created was too small to harness cheap fusion power, the technique could have potential uses in medicine, spacecraft propulsion, the oil drilling industry and homeland security, said Seth Putterman, a physicist at the University of California at Los Angeles.

Putterman and his colleagues at UCLA, Brian Naranjo and Jim Gimzewski, report their results in Thursday's issue of the journal Nature.

Past derision
Previous claims of tabletop fusion have been met with skepticism and even derision by physicists.

In one of the most notable cases, Dr. B. Stanley Pons of the University of Utah and Martin Fleischmann of Southampton University in England shocked the world in 1989 when they announced that they had achieved so-called cold fusion at room temperature. Their work was discredited after repeated attempts to reproduce it failed.

Another technique, known as sonoluminescence, generates heat through the collapse of tiny bubbles in a liquid. Some scientists claim that nuclear fusion occurs during the reaction, but those claims have sparked sharp debate.

Fusion experts said the UCLA experiment will face far less skepticism because it conforms to well-known principles of physics.

"This doesn't have any controversy in it because they're using a tried and true method," David Ruzic, professor of nuclear and plasma engineering at the University of Illinois at Urbana-Champaign, told The Associated Press. "There's no mystery in terms of the physics."

In a Nature commentary, Michael Saltmarsh of the Oak Ridge National Laboratory said the UCLA process was in some ways "remarkably low-tech," drawing upon principles that were first recorded by the Greek philosopher Theophrastus in 314 B.C.

Ultimate energy source
Fusion power has been touted as the ultimate energy source and a cleaner alternative to fossil fuels like coal and oil. Fossil fuels are expected to run short in about 50 years.


In fusion, light atoms are joined in a high-temperature process that frees large amounts of energy. It is considered environmentally friendly because it produces virtually no air pollution and does not pose the safety and long-term radioactive waste concerns associated with modern nuclear power plants, where heavy uranium atoms are split to create energy in a process known as fission.

In the UCLA experiment, scientists placed a tiny crystal that can generate a strong electric field into a vacuum chamber filled with deuterium gas, a form of hydrogen capable of fusion. Then the researchers activated the crystal by heating it.

The resulting electric field created a beam of charged deuterium atoms that struck a nearby target, which was embedded with yet more deuterium. When some of the deuterium atoms in the beam collided with their counterparts in the target, they fused.

The reaction gave off an isotope of helium along with subatomic particles known as neutrons, a characteristic of fusion. The experiment did not, however, produce more energy than the amount put in — an achievement that would be a huge breakthrough.

Commercial uses
UCLA's Putterman said future experiments will focus on refining the technique for potential commercial uses, including designing portable neutron generators that could be used for oil well drilling or scanning luggage and cargo at airports.

The technology also could conceivably give rise to implantable radiation sources, which could target cancer cells while minimizing damage to healthy tissue. "You could bring a tiny crystal into the body, place it next to a tumor, turn on the radiation and blast the tumor," Putterman told MSNBC.com.

In the Nature report, Putterman and his colleagues said the crystal-based method could be used in "microthrusters for miniature spacecraft." In such an application, the method would not rely on nuclear fusion for power generation, but rather on ion propulsion, Putterman said.

"As wild as it is, that’s a conservative application," he said.

This report includes information from The Associated Press and MSNBC's Alan Boyle.

Q My boyfriend, Terence, is an adventurous physics student always looking for new ways to improve our sex life. Recently he has been talking about Einstein and relativity, suggesting that we should try having sex at the speed of light or faster. But I am worried. If we were to engage in consensual sex at faster than the speed of light, would I go back in time, so that he would end up having sex with a 5 year old girl? And what are the potential legal implications of this?
Ashweena


A The area of physics which deals with speeds comparable to the speed of light is called relativity. Unfortunately for this question, Einstein’s special theory of relativity says that it is absolutely impossible for any information or matter to travel faster than the speed of light. This is backed up by a significant amount of experimental data and mathematical rigour. However, we can use relativity as a model to see what happens at speeds close to that of light.
