World Hot Topics Blog : Drugs urgently needed to fight superbugs.

World Hot Topics Blog

Drugs urgently needed to fight superbugs.

New antibiotics need to be developed urgently to combat 12 families of bacteria, the World Health Organization says, describing these "priority pathogens" as the greatest threats to human health.

The United National health agency said many of these bacteria have already evolved into deadly superbugs that are resistant to many antibiotics.
The bugs "have built-in abilities to find new ways to resist treatment" the WHO said, and can also pass on genetic material that allows other bacteria to become drug-resistant.

Governments need to invest in research and development (R&D)if new drugs are to be found in time, because market forces cannot be relied upon to boost the funds needed to fight the bugs, it said.

"Antibiotic resistance is growing, and we are fast running out of treatment options," the WHO's assistant director-general for health systems and innovation, Marie-Paule Kieny, said.

"If we leave it to market forces alone, the new antibiotics we most urgently need are not going to be developed in time."

In recent decades, drug-resistant bacteria, such as Staphylococcus aureus (MRSA) or Clostridium difficile, have become a global health threat, while superbug strains of infections such as tuberculosis and gonorrhoea are now untreatable.

The WHO has previously warned that many antibiotics could become totally redundant this century, leaving patients exposed to deadly infections and threatening the future of medicine.
The "priority pathogens" list published by the WHO on Monday has three rankings - critical, high and medium - according to how urgently new antibiotics are needed.

The critical group includes multidrug-resistant bacteria that pose a particular threat in hospitals, nursing homes, and other care facilities. These include Acinetobacter, Pseudomonas and various Enterobacteriaceae that can cause severe and often deadly infections such as pneumonia and septicaemia. The second and third tiers contain other increasingly drug-resistant bacteria that cause more common diseases such as gonorrhoea and food poisoning caused by salmonella.

The WHO said the list is intended to spur governments to put in place policies that incentivise basic and advanced R&D.

Georgia state House votes to allow guns on public college campuses

Georgia state House votes to allow guns on public college campuses

By David Beasley

ATLANTA (Reuters) - Concealed handguns would be allowed on Georgia's public college campuses under a measure that cleared the state's House of Representatives on Monday and now heads to the Senate over the objections of university leaders.
The bill would let anyone 21 or over with a concealed weapons permit take their handguns on public college campuses but not into dormitories, fraternity and sorority houses or sporting events.
World Hot Topics Blog
"The House took a very clear position that the Second Amendment does not stop at the edge of a college campus," Speaker David Ralston, a Republican, said following passage of the bill, the Atlanta Journal-Constitution reported.

A Democratic opponent of the bill, State Representative Robert Trammell, said in a phone interview on Tuesday that he believed the U.S. Constitution's Second Amendment allowed handguns to be barred from "sensitive" places such as college campuses.
"In addition to the question of public safety, a weapon in a classroom environment is antithetical to the idea and mission of post-secondary education," Trammell said.
Supporters of the measure have cited several recent armed robberies of students in the library at Georgia State University in downtown Atlanta as evidence that students should be allowed to arm themselves.
World Hot Topics Blog
But Trammell said there is no data showing that campuses would be safer if students were allowed to carry weapons.

The Georgia Board of Regents, which governs the state's colleges and universities, opposes the bill, spokesman Charles Sutlive said. The Georgia legislature defeated a similar bill in 2014.
World Hot Topics Blog
Last week, the president of the University of Texas reluctantly approved plans that would allow licensed concealed handgun holders to bring pistols into classrooms, after the Texas legislature last year approved a "campus carry" law similar to the one proposed in Georgia.
Georgia's bill covers only public colleges. Texas allows private colleges to opt out of campus carry, and most of the best-known private schools have.

Should Obama Change His Approach to the Islamic State Group After Paris?

World Hot Topics Blog

Should Obama Change His Approach to the Islamic State Group After Paris?
The world is still reeling from deadly terrorist attacks in Paris last Friday, and with fears of a similar assault in the U.S., some have criticized President Barack Obama for dismissing calls to scale up U.S. military efforts against the Islamic State group and for doubling down on his approach thus far.  World Hot Topics Blog
"We have always understood that this will be a long-term campaign," the president said, speaking at the G-20 summit in Turkey on Monday. "There will be setbacks and there will be successes. The terrible events in Paris were obviously a terrible and sickening setback." Obama also rejected calls to put ground troops in Syria, saying, "It's best that we don't shoot first and aim later." The president's deputy national security adviser Ben Rhodes underscored Obama's approach, saying, "We don't believe U.S. troops are the answer to the problem." Other Obama advisers, The New York Times reports, say the administration is considering several response options, which include aiding allies in the region, more airstrikes and raids by special operations forces. World Hot Topics Blog
But Republicans are slamming the president's game plan against the Islamic State group and response to the Paris attacks. 2016 GOP hopeful and former Florida Gov. Jeb Bush admonished Obama, saying he "doesn't understand we're at war." South Carolina Sen. Lindsey Graham, also a Republican presidential candidate, advocated for U.S. ground troops in the region, telling CNN that "without American boots on the ground in Syria and Iraq, we're going to get hit here at home. And if you don't understand that, you're not ready to be commander-in-chief, in my view."
Even Hillary Clinton, the front-runner in the Democratic presidential race, has insisted the U.S. amp up its efforts to defeat the Islamic State group. While she agreed that boots on the ground are not the answer, she refuted Obama's assertion that the group had been "contained" and called for increased airstrikes and a no-fly zone in northern Syria. She also noted the 50 special operations soldiers Obama ordered to Syria last month have not left yet and must be "immediately" deployed.
The president, for his part, announced new counterterrorism efforts on Monday to prevent another tragedy like Paris. "We're streamlining the process by which we share intelligence and operational military information with France," he said at the G-20 summit, adding that "we need to be doing everything we can to protect against more attacks and protect our citizens."

So should Obama change his approach to the Islamic State group after the Paris attacks? Here's the Debate Club's take:

Two Deaths Confirmed In Cucumber Salmonella Outbreak

World Hot Topics Blog

Two Deaths Confirmed In Cucumber Salmonella Outbreak

9/10/2015 3:45 PM ET

Two people have reportedly died as a result of a salmonella outbreak linked with cucumbers. The Centers for Disease Control has confirmed a total of 341 cases directly linked with the cucumbers, which were imported from Mexico.

The CDC released an official statement on the outbreak.
World Hot Topics Blog
"Seventy ill people have been hospitalized, and two deaths have been reported from California and Texas. Arizona, California, Montana, and Nevada isolated Salmonella from samples of cucumbers collected from various locations that were distributed by Andrew & Williamson Fresh Produce," the CDC explained.

"Consumers should not eat, restaurants should not serve, and retailers should not sell recalled cucumbers," they added. "If you aren't sure if your cucumbers were recalled, ask the place of purchase or your supplier. When in doubt, don't eat, sell, or serve them and throw them out."

What are the Symptoms of Salmonella

Most people infected with Salmonella develop diarrhea, fever, and abdominal cramps. The illness usually lasts 4 to 7 days, and most people recover without treatment. It is important to note that this outbreak is caused bySalmonella Poona.
World Hot Topics Blog

How Soon do Symptoms Appear After Exposure? 

Most people infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection. 

What are the Complications of Salmonella Infections? 

In some people, the diarrhea may be so severe that they need to be hospitalized. In these patients, theSalmonella infection may spread from the intestines to the blood stream, and then to other body sites and can cause death unless the person is treated promptly with antibiotics. 
World Hot Topics Blog

Who is at Risk?

Children are the most likely to get salmonellosis. The rate of diagnosed infections in children less than five years old is higher than the rate in all other people. Children younger than 5 years of age, the elderly, and those people with weakened immune systems are more likely to have severe infections. It is estimated that approximately 400 persons in the United States die each year with acute salmonellosis.

Bacteria that can help fight cancer

World Hot Topics Blog

Bacteria that can help fight cancer
New York, June 9 (IANS) A toxin secreted by a water and food-borne bacterium that can cause lethal infections in persons with liver disease, has the potential to prevent the growth of tumours, says a new study by Northwestern Medicine scientists.

"A toxin protein from the bacterium Vibrio vulnificus can inhibit tumour cell growth by cutting the protein Ras," researchers said.
"Ras is important for cell proliferation in cancer, so the toxin could potentially be developed as a treatment for different types of tumours," said one of the researchers Karla Satchell, professor in microbiology-immunology at Northwestern University Feinberg School of Medicine in the US.                  World Hot Topics Blog

"The bacterium uses the MARTX (multifunctional-autoprocessing repeats-in-toxin) toxin protein to inactivate Ras, increasing its own virulence and allowing it to spread throughout the host," the study said.

"It has been known that Ras has a role in cancer development and targeting Ras has been one of the hardest challenges of cancer research and drug discovery," Satchell said.
The findings appeared in the journal Nature Communications.

Toronto tunnel mystery solved, say police

World Hot Topics Blog

Toronto tunnel mystery solved, say police

Ottawa (AFP) - Toronto police said Monday they now know who dug a tunnel near a major sporting venue in the city -- a mystery that has been a source of widespread speculation and conspiracy theories.

In a statement, police said two young men stepped forward to acknowledge responsibility after authorities made a public plea for help to determine its purpose.

"The two men told investigators they built the tunnel for personal reasons," police said.

They added that their account has been verified, and that authorities "are satisfied there was neither criminal intent nor any threat to the people or city of Toronto." World Hot Topics Blog

The tunnel, which also is situated near Toronto's York University, was discovered by a wildlife official walking through woods. He spotted a piece of corrugated metal on the ground, lifted it up and found a passageway.

It was more than six feet (1.8 meters) high, almost three feet (0.9 meters) wide and about 33 feet (10 meters) long, and was hidden in a densely wooded area of the city, "well off the beaten path," deputy police chief Mark Saunders told a press conference last week.

Image released on February 24, 2015 by the Toronto Police shows the inside of a tunnel found near Yo …

Had it continued, the tunnel would have exited on the other side of a hill overlooking nearby tennis courts and a sports facility that will host the Pan American Games in July. World Hot Topics Blog

Its discovery provoked widespread speculation about who built it and why. 

National security officials were alerted, but suggestions the tunnel posed a threat were quickly dismissed. Police also said it was not a drug lab.

Online sleuths and media suggested it could be a survivalist's fallout shelter, a prank, or a niche home in Toronto's red hot condo market.

American horror writer Stephen King weighed in that it was likely a wormhole built by aliens.

Before it was filled in, the second in command of Canada's largest city police force described the interior of the tunnel as humid and warm.

The walls were lined with plywood and reinforced with wood framing. It was lit by an electric generator and a sump pump was used to keep it dry.

Police also found a bucket and pulleys and a wheelbarrow likely used in the dig.

As well, a rosary with a poppy attached was nailed to an inside wall, and discarded food and beverage containers point to someone having used the tunnel over the winter, Saunders said.

Ayurveda And Multitasking - World Hot Topics Blog

 World Hot Topics Blog

Ayurveda And Multitasking 

Multitasking is a key word for todays lifestyle. Each of us do it with our thoughts. 

is it really helpful for our body &  health ?

What exactly multitasking mean? 

How does it affects our health? 

Let's solve all this in Ayurveda way.

As it indicate, multitasking means doing more than one work at a time. 

Usually this refer to have more thoughts at a single time.

Thought is created by brain. Brain is located in skull, at upper most part of body. Brain works on glucose & oxygen supplied by blood. This blood is supplied by heart.

So, when we have a single thought brain is working in single way. As thought is brains own work it did not disturb its rythum. Heart too supply in a single rythumic way. This is a ideal situations for these vital organs. Nobody get hurts.
But, at multitasking, having more thoughts, brain have to work fast. Brain needs to work on several levels. At this point brains own rythum gets disturb. It requires more energy, so heart has to pump the blood towards the brain, against the gravity, which again requires more energy to heart. This all disturbed the working rhythm of brain & heart.

Surely, individual can't get hurt in a single incident. But because of this disturb rhythm these vital organ, VATT dosha get increase. Resulting in many unwanted sings like,

Loss of concentration
Head ache
Memory loss
Harmonal changes
Short temperness
Hyperactivity & Hyperness 
 World Hot Topics Blog

In many more cases Multitasking is a root cause for a disease. 

So, how can we avoid it.

First accept the thing that multitasking hurts. 

As you accept it, you will start to avoid it. 

In Ayurveda, there are two ways for it.

1) To improve strength of brain & heart with medication, good food, & by changing lifestyle.
2) To concentrate on single topic at a single time. If a second though comes in note it down, but don't keep in brain. Finish the first one & then go to second. 

This is called Switch on, Switch off method. This method looks difficult, but after some practice, you can enjoy the power of your brain. 

Hope this Helps to all busy Multitaskers

5 ways to survive Your first freeze.

World Hot Topics Blog

 5 ways to survive Your first freeze.

Editor's note: Charles W. (Chuck) Bryant is the co-host, with Josh Clark, of Discovery Channel's 'Stuff You Should Know.' The pair has released nearly 600 episodes of their award-winning show since 2008.
(CNN) -- If you're from, say, the Midwest or Northeast or Alaska, dealing with the cold is not only a way of life, but also a point of pride: You can take care of yourself, and you're not shy about pointing it out. But, as evidenced by this week's "polar vortex," cold weather can barrel through many parts of the country — Georgia, Florida, Arkansas — where people aren't used to sub-freezing temperatures.
There are some true life-threatening scenarios, like a car breaking down on a rural stretch of wintery road (always pack a blanket), but it can be dangerous even in your own home if you're caught without the necessities you need to keep warm, and this is especially true for the elderly.
If you're in a part of the United States new to this kind of severe weather, here are some suggestions to help you help yourself.
 World Hot Topics Blog
 1: Wind chill can kill
Wind chill is the effect of moving air on exposed skin, a term coined by Antarctic explorer Paul Siple in the late 1930s to help describe how wind figures into heat loss. He experimented with wind chill's effect by timing how long it took to freeze water in varying degrees of wind strength. If you're not used to bitter wind chill, realize that you need to take it seriously when preparing for any outdoor activities. Skin exposed for five minutes in below-zero wind chill conditions can get frostbite. Longer can do worse.
Two University of California at Berkeley economists found that deaths related to cold reduced the average life expectancy of Americans by a decade, if not more. In countries where people were exposed to 10 or fewer days a year, the death rate was substantially higher than in countries with at least 90 cold days a year.
Additionally, cold weather can leave us without our thinking caps, willing to do whatever it takes to warm up. This can indirectly lead to unexpected fatalities because of accidents relating to carbon monoxide poisoning and house fires.

 World Hot Topics Blog

 2: Hypothermia and layering
Hypothermia -- when your body temperature falls to 95 degrees F -- is a grim possibility if you're facing the cold without power, and layering your clothing is your best first defense against it. If you're experiencing slurred speech, stiff joints, a loss of coordination, uncontrollable shivering, loss of bladder control, puffy face or mental confusion, you could be suffering from hypothermia, which can be fatal. To combat this, get yourself into a warmer environment as soon as you can. Cover yourself with any items you can find -- blankets, sleeping bags, pillows. Just as you layer your upper body clothing, you should also layer what you have on your feet. Try a thin pair of nylon, silk or wool socks for starters -- then layer with additional wool socks. If you think a loved one is suffering from hypothermia, you should handle that person with great care, as the condition could make it easy for him or her to go into cardiac arrest.
Keep them horizontal and calm, and reassure them that they're going to be fine. Use each other's body heat to warm up by getting into a sleeping bag together or simply hugging each other tight to create warmth. And, of course, seek medical attention as soon as possible.

3: Wear a hat, despite the myth
You've probably heard the popular myth that you lose most of your body heat through your head. This myth was perpetuated by an outdated U.S. Army survival training manual that stated that 40% to 50% of our body heat is lost through the head. The truth is, you lose the same amount of heat through your head as you would any part of your body that is exposed to the elements However, you're way more likely to go out into the cold without a warm hat, than say, a shirt or a pair of shoes. But just because you don't lose more heat through your head doesn't mean you should leave your winter hat on the rack. Wearing a touque is a great way to assist your heavy coat, gloves, boots and snow pants in keeping all of you warm. Think of it as capping off your winter clothing plan.

 World Hot Topics Blog

4: Keep Hydrated
Hydration isn't just a warm weather worry. Many people forget that you need water in the freezing cold just as much as you do in hot weather. If your pipes are frozen, eating some snow or ice may seem like a great idea, but it will lower your core temperature and actually bring on dehydration. You can melt the snow or ice, but remember that while it can be safe to ingest in more remote locations, drinking water from melted "city snow" is a risk. You'll also want to avoid drinking only coffee or alcohol as a warming technique. I know this one is tough to resist since it may give you a short-term warm up, but it'll dehydrate you much more quickly. If you must indulge, remember to also drink plenty of water along with your coffee or toddy.

5: Light Your Fire
A fire is the best way to fight a winter chill if you're stuck in your home without power. And this means only fireplaces. You should never use your gas oven or stove to warm up under any circumstances as it could lead to carbon monoxide poisoning. But if you have a fireplace or a kerosene heater you're in luck. Use your fireplace as your main heat source, and if you can, sleep in the room with it — just not too close and with a protective fire screen. The last thing you want to do is wake up to find that fire has moved from the fireplace to your living room carpet.
If this vortex leaves you worried that winters could be severe in your part of the country from now on, before the next one, make sure you have a nice stockpile of wood, as it will be tougher to find once a storm hits, and outages can last days or weeks depending on how severe the weather is and how competent our utility company is in restoring power.
And here's a new summer task to consider: Make sure your chimney is clear and clean before the chimney sweeps are all booked up — and the next vortex swoops down from the north.
