Scientists at Drexel University in Pennsylvania have developed a technology that can heat water faster up to three times. This can be really helpful in conserving energy in industrial power plants or large-scale electronic cooling systems. It can also be used to make tea quickly, technically speaking.

The air bubbles created while heating water temporarily insulate heating elements from the surrounding water, slowing down the transfer of heat. The scientists have found that the size of these bubbles can be reduced by coating a heating element with a virus found on tobacco plants.

The reduction in bubble size will also prevent ‘critical heat flux’ caused when bubbles merge into a blanket surrounding the element hampering the transfer heat to the water.

‘What happens then is the dry surface gets hotter and hotter, like a pan on the stove without water in it. This failure can lead to the simple destruction of electronic components, or in power plant cooling applications, the catastrophic meltdown of a nuclear reactor.’  Matthew McCarthy, an engineer at Drexel University was quoted in the PSFK magazine.

Scientists had been looking for ways to develop a surface that repels bubbles and keep the boiling surface wet. McCarthy’s team found that tobacco mosaic virus was perfect for the purpose.

They have genetically modified the virus so that it can attach itself to any surface. Once the virus is attached to the surface, it is coated with a microscopically thin layer of nickel to make the virus inert.  This forms a sort of metallic grass which can wick moisture to the surface and repel bubbles.

Texas Mass Shooting: ‘It isn’t a guns situation, but a mental problem’, Says Trump

An eyewitness to the shootings, who is a Vietnam War vet, told VOA's Mehtap Colak Yilmaz that he had not seen anything like the church massacre "since Vietnam."

White House, November 6, 2017 : A man opened fire with an assault weapon at a church near San Antonio, Texas, Sunday morning, killing 26 worshippers and wounding at least 20.

The victims range from five to 72 years old.

The gunman is also dead and there is no clue so far as to his motive.

Federal investigators from the FBI and the Bureau of Alcohol, Tobacco, and Firearms have joined local law enforcement officers in tiny Sutherland Springs, Texas, about 50 kilometers from San Antonio.

On Monday, U.S. President Donald Trump said the mass shooting “isn’t a guns situation” but is instead “a mental health problem at the highest level. It’s a very, very sad event.” He said the shooter was “a very deranged individual.” The president is monitoring the situation from Japan, the first stop on his five-nation Asian trip.

Earlier, Trump called the shootings “an act of evil” and appealed for prayers. He ordered U.S. flags on federal buildings to be flown at half-staff through Thursday.

“We cannot put into words, the pain and grief we all feel and we cannot begin to imagine the suffering of those who lost the ones they so dearly loved. Our hearts are broken,” the president said.

Texas Governor Gregg Abbott says this is worst mass shooting in Texas history. He said there are “many pieces of a complex puzzle” to put together.

What is known, according to Texas public safety official Freeman Martin, is that the gunman, later identified as Devin P. Kelley, was described as a young white male dressed in black and wearing a bullet-proof vest. He first opened fire with an assault rifle outside the First Baptist Church and continued shooting after going inside.

Freeman said a local resident with his own rifle confronted the shooter, causing the gunman to drop his weapon and flee in his car. The citizen pursued the gunman, joined shortly by police. Freeman said the suspect crashed the car just over the county line and was found dead in the vehicle from a gunshot wound. It is unclear if he killed himself or was shot by the citizen.

Wilson County Sheriff Joe Tackitt says police found multiple weapons in the suspect’s car.

U.S. Air Force spokeswoman Ann Stefanek told VOA late Sunday that records show Kelley was discharged from the Air Force about three years ago: “Records checks confirm Devin P. Kelley was previously a USAF member, who served in Logistics Readiness at Holloman AFB, NM, from 2010 until his discharge in 2014. Kelley was court-martialed in 2012 for two counts of Article 128 UCMJ ((EDS: Uniform code of Military Justice)) — assault on his spouse and assault on their child. Kelley received a Bad Conduct Discharge, confinement for twelve months and a reduction to the grade of E-1.”

Two of the victims were killed outside the church. The rest were shot inside.

An eyewitness to the shootings, who is a Vietnam War vet, told VOA’s Mehtap Colak Yilmaz that he had not seen anything like the church massacre “since Vietnam.”

Marie Ann Montgomery, the church’s Sunday school director, told VOA’s Yilmaz that people in the congregation knew Kelley and some of the suspect’s family members were among the victims. Montgomery stopped short, however, of saying the suspect deliberately targeted his family.

While none of the victims have been publicly identified, First Baptist Church Pastor Frank Pomeroy told U.S. news networks that his 14-year-old daughter, Annabelle Renee Pomeroy, is among the deceased.

Pomeroy was in Oklahoma at the time of the shooting. He told ABC News he was on his way back to Sutherland Springs.

​He said all of the people killed Sunday were close friends. Pomeroy also said he wants the world to know his daughter “was one very beautiful special child.”

Sheriff Tackitt says the church posts its weekly services on YouTube and that the massacre was likely caught on camera. The FBI says it believes only one gunman was involved.

Sunday’s Texas shooting comes just weeks after October’s mass killing in Las Vegas. Stephen Paddock opened fire on a country music show there, killing 58 and wounding about 500. Paddock shot from his 32nd floor hotel room and killed himself as police moved in. Investigators in the Las Vegas shooting are still working to confirm a motive. (VOA)

Is Vaping Safer Than Smoking? New Research Suggests Why You Should Switch

While the best approach for a healthy life is to entirely quit smoking, but the most critical thought is that smoker stop smoking tobacco in the first place

Washington, October 6, 2017 : In present day societies, smoking is considered ‘cool’. Unfortunately, in this race to look trendy, the practice has become one of the biggest man-made killers. Today, tobacco consumption is among the world’s leading causes of preventable death and takes as many as six million lives every year.

While quitting smoking is difficult, a new research suggests e-cigarettes are far safer than smoking and can add multiple years to anyone who switches.

According to a new cancer research team, if all smokers switch to e-cigarettes and similar vaping devices exclusively, they could live for 86.7 million years in total.

The study has been carried out by Georgetown Lombardi Comprehensive Cancer Center.

The Research 

According to David Levy, the lead author of the study and a professor of oncology at Georgetown Lombardi, the study has been carried out to encourage “replacing cigarette smoking with vaping to yield substantial life year gains,”

The study is the first ever theoretical piece to trace the health outcomes of people who are choosing to quit smoking and shift to different vaping devices.

The study relied upon multiple factors like,

  • When a subject began smoking
  • when they quit smoking
  • when they switched from smoking a cigarette to vaping

Studying the responses, the researchers anticipated both a hopeful result and a negative result.

Pessimistic Result : 1.6 million would add a 20.8 million years to their lives.

Optimistic Result : 6.6 million cigarette smokers would include 86.7 million years from switching.

These results suggest that even in the grimmest outcome, vapors live more instead of those who inhale deadly measures of toxicants with cigarette smoke.

A switch from smoking to vaping will not only add years to an individuals’ life, but will also have multiple benefits on general health. According to Professor Levy, “There would be tremendous health benefits including reduced disease disability to smokers, reduced pain and suffering, and reduced exposure to secondhand smoke”

Is Vaping Safer Than Smoking?

E-cigarettes and other vaping devices do not contain tobacco. Instead, they contain a nicotine-filled liquid which is heated to produce vapor, which in turn is inhaled. This satisfies the cravings known to be associated with cigarette addiction.

While it will be wrong to say that these devices are completely harmless, it can be said that these devices to not cause life-threatening diseases like cancer- which tobacco does.

In this way, e-cigarettes are far safer than smoking.

While the best approach for a healthy life is to entirely quit smoking, but the most critical thought is that smoker stop smoking tobacco in the first place.

The study has been published in a global journal that studies and analyses the effect of tobacco abuse called Tobacco Control.

London, September 15, 2017 : Heart disease and tobacco ranked with conflict and violence among the world’s leading cause of poor health and the biggest killers in 2016, while poor diets and mental disorders caused people the greatest poor health, a large international study has found.

The Global Burden of Disease (GBD) study, published in The Lancet medical journal, found that while life expectancy is increasing, so too are the years people live in poor health. The proportion of life spent being ill is higher in poor countries than in wealthy ones.

“Death is a powerful motivator, both for individuals and for countries, to address diseases that have been killing us at high rates. But we’ve been much less motivated to address issues leading to illnesses,” said Christopher Murray, director of the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, which led the study.

He said a “triad of troubles” — obesity, conflict and mental illness — is emerging as a “stubborn and persistent barrier to active and vigorous lifestyles.”

Diet critical

The IHME-led study, involving more than 2,500 researchers in about 130 countries, found that in 2016, poor diet was associated with nearly one in five deaths worldwide. Tobacco smoking killed 7.1 million people.

Diets low in whole grains, fruit, nuts and seeds, fish oils and high in salt were the most common risk factors, contributing to cases of obesity, high blood pressure, high blood sugar and high cholesterol.

The study found that deaths from firearms, conflict and terrorism have increased globally, and that noncommunicable, or chronic, diseases such as cardiovascular disease and diabetes caused 72 percent of all deaths worldwide.

Heart disease was the leading cause of premature death in most regions and killed 9.48 million people globally in 2016.
