The #NobelPrize committee couldn't reach Paul Milgrom to share the news that he won, so his fellow winner and neighbor Robert Wilson knocked on his door in the middle of the night. pic.twitter.com/MvhxZcgutZ— Stanford University (@Stanford) October 12, 2020 275

The attorney for the limousine company whose vehicle crashed in upstate New York on Saturday disputed statements from officials that the stretched Ford Excursion should have never been on the road.Prestige Limousine & Chauffer Service attorney Lee Kindlon said the state Department of Transportation conducted a periodic inspection last week and discovered "minor safety infractions" including inoperative or defective windshield wipers and a broken latch on a window.Both issues were fixed and, "as recently as last week they were told by the Department of Transportation that they could, that this vehicle was roadworthy and they could drive it," Kindlon said. "I am disputing that any recent failures of minor safety defects contributed to this crash," he said.State officials charged back, saying the vehicle was not allowed to be in service."The assertion that the limousine was cleared to be on the road following the September inspection is categorically false," said Joseph Morrissey, spokesman for the New York State Department of Transportation, in a statement. "The vehicle was subject to inspections and the owner was warned not to operate the vehicle; the vehicle was placed out of service."For reasons still unknown, the limo plowed through a stop sign in Schoharie and crashed into a parked SUV. The crash left 20 people dead, including the 17 passengers who rented the limo for a birthday party, two pedestrians and the driver.Federal, state and local investigators have flooded Schoharie to try to understand what caused the deadliest U.S. transportation accident in almost a decade. The wreck has placed Prestige Limousine Chauffeur Service and its owner, Shahed Hussain, under scrutiny. 1717

STOCKHOLM (AP) — Americans Harvey J. Alter and Charles M. Rice and British-born scientist Michael Houghton have won the 2020 Nobel Prize in medicine for their discovery of the hepatitis C virus.The World Health Organization estimates there are over 70 million cases of hepatitis worldwide and 400,000 deaths each year.The disease is chronic and a major cause of liver inflammation and cancer.The Nobel committee says, “thanks to their discovery, highly sensitive blood tests for the virus are now available," a development that has greatly reduced the chances of getting hepatitis C through blood transfusions.The medicine prize carries particular significance this year due to the coronavirus pandemic, which has highlighted the importance of medical research. 769

Tall people are at a greater risk of cancer because they have more cells in their body, new research has suggested.A person's risk of developing cancer increases by 10 percent for every 10 centimeters (4 inches) they are over the average height, the study said, because they have more cells which could mutate and lead to cancer.Average height was defined in the study as 162cm (5 feet, 4 inches) for women and 175cm (5 feet, 9 inches) for men.The findings match with previous research, which has also connected height to an increased risk of developing a range of health problems including blood clots, heart problems and diabetes.Leonard Nunney, a professor of biology at the University of California Riverside, analyzed previous sets of data on people who had contracted cancer -- each of which included more than 10,000 cases for both men and women -- and compared the figures with anticipated rates based on their height.He tested the hypothesis that this was due to the number of cells against alternatives, such as possible hormonal differences in taller people, which could lead to an increased rate of cell division.A link was found between a person's total cell number and their likelihood of contracting cancer in 18 of the 23 cancers tested for, the study says.The research also found that the increase in risk is greater for women, with taller women 12 percent more likely to contract cancer and taller men 9 percent more likely to do so. Those findings matched with Nunney's predicted rates, using his models, of 13 percent for women and 11 percent for men.Colon and kidney cancer and lymphoma were among the types of cancer for which the correlation was strongest."We've known that there is a link between cancer risk and height for quite a long time -- the taller someone is, the higher the cancer risk," Georgina Hill from Cancer Research UK told CNN."What we haven't been sure of is why -- whether this is simply because a taller person has more cells in their body, or whether there's an indirect link, such as something to do with nutrition and childhood," added Hill, who was not involved in the study.She said the study provides good evidence of the "direct effect" theory that the total number of cells does indeed cause the link."The methodology is good - they took data from large studies, which is important, and they looked at lots of different categories of cancer."But she noted that the increase in risk of developing cancer is small compared to the effects that lifestyle changes can have."It was only a slightly higher risk and that there are more important actions that people can take to make positive changes, [such as] stopping smoking and maintaining a healthy weight," she said.Two of the types of cancer tested for, thyroid cancer and melanoma, were found to be more susceptible to an increase in risk than expected, and Nunney suggested in the study that other factors could be at play in those cases, such as geography."There are no obvious reasons for these exceptions, although the author speculates that cell turnover rates may come into play for melanoma," Dorothy C. Bennett, director of the Molecular and Clinical Sciences Research Institute in London told CNN. Bennett, who was not involved in the study, explained that pigment cells, the source of melanoma, divide and are replaced a little faster in taller people."But I cannot at present think of any reason why this [faster division] should be so, but nor any other clear reason for the higher correlation with height," Bennett said. 3548

Terrible shootings in ElPaso, Texas. Reports are very bad, many killed. Working with State and Local authorities, and Law Enforcement. Spoke to Governor to pledge total support of Federal Government. God be with you all!— Donald J. Trump (@realDonaldTrump) August 3, 2019 285
