A research team from the Massachusetts Institute of Technology and Colorado State University of the US and the University of Sheffield of the UK has analysed effects of global warming and ozone pollution over 2000–2050 on the worldwide production of wheat, rice, maize and soybean. The study was published in journal Nature Climate Change yesterday.

The scientists found reduction of crop yields by 2050 exceeded 10% of 2000 levels, substantially decreasing food security, in all cases examined. Several scenarios were considered because of uncertainty of future levels of ozone pollution.They estimated by 2050, increasing population and changing diet would increase world food needs by 50 percent.As coauthor Colette Heald told The Huffington Post, “The climate projections are quite consistent […] the future of ozone pollution is very different […] leading to either offsetting or reinforcing effects [of climate change] on crops”.By 2050, undernourishment would increase by either 49 percent or by 27 percent, depending on the scenario.

The study focuses on ozone–temperature covariation: ground-level ozone increases with temperatures.Heald said although temperature and ozone are separately known to impact crop yields, “nobody has looked at these together”.Depending on region and crops, the yields may be primarily sensitive to ozone —in the case of wheat— or heat —in the case of maize— alone, providing a local estimation of relative benefits of climate change adaptation versus ozone regulation.

The U.S. Department of Agriculture notes, “Ground-level ozone causes more damage to plants than all other air pollutants combined”, highlighting the importance of air quality for agriculture. Results of NCLAN studies, published in a paper by AS Heagle in 1989, show dicot species, such as soybean, cotton, and peanut, lose more yield from ozone than do monocot species such as sorghum, field corn, and winter wheat.The researchers found that ozone pollution caused 46 percent of previously heat-attributed damage to soybean crops.

The model does not include the effect of rising carbon dioxide concentration, which has complex and potentially offsetting impacts on global food supply.The U.S. Environmental Protection Agency says some crops may have higher yields with increased levels of carbon dioxide.However, global warming also increases probability of extreme crops-damaging weather events such as floods, droughts, and extreme temperatures. Climate change affects distribution of weeds, pests, and diseases.Heald noted the findings show pollution reduction is also important. “An air-quality cleanup would improve crop yields […] Ozone is something that we understand the causes of, and the steps that need to be taken to improve air quality.”

As Heald told The Huffington Post, US surface ozone has dropped partly due to the Clean Air Act. “Despite an increase in vehicle miles driven and energy consumption, surface ozone has declined by 25 percent on average across the U.S. from 1980 to 2012 […] However, the future of ozone air quality in the U.S. and around the world will depend on local emissions, the use of pollution control technology, regulations, and air quality policy.”

The study was supported by the Croucher Foundation, US National Science Foundation, and US National Park Service.

A magnitude 6.7 earthquake shook the Hawaiian islands at 17:07:49 UTC (07:07:49 local time) October 15, 2006. The quake, centered approximately 6 miles southwest of Puak? on the west side of Hawai`i Island (the Big Island), was felt throughout the entire state, causing a statewide power outage.

No tsunami warning was issued as a result of the quake; however, a tsunami measuring around 0.1 meters (four inches) was recorded. There were 50 aftershocks reported after the quake, the strongest being a 5.8 tremor reported at about 17:14 UTC (7:14 a.m. local time).

There were no fatalities reported and only scattered reports of minor injuries.

Electric power was lost statewide shortly after the quake. As of about 8:00 p.m. HST, power was restored to all the neighbor islands, but Hawaiian Electric personnel still had work to go on Oahu, the island with the highest population. Power was eventually restored to most areas of Oahu by midnight.

Structural damage occurred at Kona Hospital, where ceiling tiles fell and electricity was lost, forcing an evacuation of patients to Hilo Medical Center on the other side of the island. Damage was also reported at the Honokaa Long-term Care Facility and the Royal Kona Resort.

Hawaii Governor Linda Lingle, who was in Kona at the time of the earthquake, issued an emergency declaration for the entire state of Hawaii at about 11:00 a.m. local time (2300 UTC Sunday).

Air service in Hawaii was temporarily suspended shortly after the quake as airports were forced to operate on emergency power. The power outage caused delays to incoming and outgoing flights, as TSA agents had to conduct manual searches of all bags. Airlines have canceled numerous flights scheduled to depart Honolulu International Airport Sunday evening.

Communication links are problematic. Most radio stations lost power and stopped broadcasting immediately after the quake. (Metroblogging Hawaii) Honolulu radio station KSSK, operating on emergency generators, became a central information source for Oahu residents. A landslide has blocked at least one major highway from a section of a cliff at Kealakekua Bay.

USGS Volcano Observatory equipment has not been significantly damaged. Monitoring stations report “no significant changes in the past 24 hours” of the eruption of the K?lauea volcano.

According to USGS records, this earthquake is the fourth largest Hawaiian earthquake in the last 100 years. Previous earthquakes include a magnitude 7.2 quake in 1975, a magnitude 6.9 quake in 1951, and a magnitude 6.8 quake in 1938. The last magnitude 6.7 quake was in 1983.

Chemicals, which the Auckland City Council said are a suspected cause of cancer and are considered toxic, have been found in soil at a children’s playcentre in Auckland. The contamination was found at the Auckland Central Playcentre in Freemans Bay, and the Council will now spend $100,000 removing the top 50 cm (about 20 in) of soil at the playcentre, doing landscaping and replacing playground equipment.

The presence of “polycyclic aromatic hydrocarbons, including benzo-a-pyrene,” was suspected at the school playground and was confirmed by a chemical analysis on Tuesday. The chemicals may cause temporary digestive and respiratory distress, as well as irritation of the eyes and skin. The levels of benzo-a-pyrene found were between 0.06 and 4.82 milligrams per kilogram of soil at surface level, according to the Ministry of Education. A potential risk is present at levels above 3.5 mg.

San Jose, California — A woman eating a bowl of chili at a Wendy’s restaurant bit into a chewy bit that turned out to be a human finger. She immediately spat it out, warned other patrons to stop eating, and upon recognizing the object as a finger, vomited.

“I’m more of a Carl’s Jr. person,” the 39-year-old Las Vegas woman, Anna Ayala, told Knight Ridder. She said this incident was her first visit to a Wendy’s restaurant. Ayala described how she found the finger, “Suddenly something crunchy was in my mouth,” she continued, “and I spit it out.”

According to Devina Cordero, 20, after Ayala found the finger, she ran up to her and Cordero’s boyfriend and said, “Don’t eat it! Look, there’s a human finger in our chili.”

“We went up to the counter and they told us it was a vegetable,” Cordero continued. “The people from Wendy’s were poking it with a spoon.”

The restaurant is located at 1405 Monterey Highway, just south of downtown San Jose.

Wikinews reporter David Vasquez drove his car up to the drive-thru menu and found that chili was still on the menu, at a price of US$1.19 for a small serving. He also witnessed workers unloading supplies from a semi-trailer truck in the restaurant’s parking lot, and carting them into the back door of the establishment.

According to Ben Gale, director of environmental health for Santa Clara County, the finger did not come from any of the employees at the restaurant. “We asked everybody to show us they have 10 fingers and everything is OK there,” he said. The found portion of the finger likely belonged to a woman because of its long and manicured fingernail, also found in the food.

Officials seized the food supply at the restaurant and are tracing it back to the manufacturer, where they believe the finger may have gotten mixed in with the raw ingredients used to prepare the chili. The restaurant’s operators were later permitted to re-open after preparing new chili prepared from fresh ingredients.

As this story was filed, there was no mention of the incident on the Wendy’s corporate web site. Wendy’s issued a statement through a spokesman.

“Food safety is of utmost importance to us,” said Wendy’s spokesman Joe Desmond. He referred to the incident as an “unsubstantiated claim.”

“We are cooperating fully with the local police and health departments with their investigation. It’s important not to jump to conclusions. Here at Wendy’s we plan to do right by our customers,” Desmond said.

According to county health officials, the unfortunate woman who bit into the finger is doing fine, despite her initial reaction. Officials also noted that the finger would have been cooked at a high enough temperature to destroy any viruses.

The Santa Clara county medical examiner reported that the finger had a solid fingerprint, although investigators did not say if a search of fingerprint databases would be performed to find the owner of the finger.

Chemotherapy is usually associated with a collection of side effects ranging from digestive problems to hair loss, but a study published this week in Human Reproduction demonstrated that female cancer patients may find they have something in common with much younger women in one specific area — their ovaries.

Scientists from the University of Edinburgh examined donated ovarian tissue from fourteen female cancer patients, most of whom had Hodgkin lymphoma, and compared it to tissue from healthy women. They found the samples from women who had been treated with a specific chemotherapeutic regimen known as ABVD not only contained greater numbers of dormant ova — egg cells — than those from women treated with harsher regimens but also more than samples from healthy women. ABVD is named for combining several drugs known as adriamycin, bleomycin, vinblastine, and dacarbazine.

These reproductive cells were not merely more plentiful in ABVD patients. They also appeared immature, “new” in the words of lead researcher Evelyn Telfer. This challenges the conventional belief that girls are born with all the ova they will ever have and the numbers can only go down as the cells are either used up by the reproductive cycle or succumb to damage or natural aging. However, further research is needed to confirm this. The study covered relatively few patients by scientific standards, and David Albertini of the Center for Human Reproduction in New York has suggested the cells may not actually be freshly grown. Instead, they may have always been there and were merely rendered more detectable by ABVD treatment.

The ability to grow new egg cells may have significant implications for women in Western societies, many of whom postpone childbearing to establish careers, sometimes into their late thirties or forties. However, Telfer warns against making use of these findings too soon: “There’s so much we don’t know about the ovary. We have to be very cautious about jumping to clinical applications.”

The experiments had been discussed earlier this year at the annual conference of the European Society of Human Reproduction and Embryology.
