Scientists struggling to know why tornado outbreaks are on the rise

US News - Fri, 12/02/2016 - 07:25

Incidents of tornado outbreaks are on the rise for the last few years, but scientists are still struggling to figure out what actually is causing the deadly outbreaks frequently.

Tornados can cause huge damages, but tornado outbreaks are even worse. A tornado outbreak occurs in the form of a storm system that spins out more than a half dozen funnels within a limited time and area.

Just a few days back, a cluster of at least 18 tornadoes hit the Southeast. Last year, such outbreaks killed 49 people, and almost 80 per cent of tornado fatalities between 1972 and 2010 took place during these outbreaks.

While many believe that climate change and warming temperatures might be affecting the frequency of tornadoes, but most scientists don't think so.

Michael Tippett, an expert at Columbia University who has long been tracking these outbreaks, said, "The number of tornadoes in outbreaks is increasing … It's not the expected signature of climate change. It could be either something else, or we really don't understand what climate change is doing."

Irrespective of their cause, these tornado outbreaks are increasingly hurting people and businesses like insurers. Bigger outbreaks mean more damage, and hefty payouts.

Twitter acquires Yes Inc.; installs Yes CEO Keith Coleman as its new product chief

US News - Fri, 12/02/2016 - 07:13

In a Thursday announcement, microbloging platform Twitter revealed that it has acquired social-networking mobile app startup Yes Inc; and has, with immediate effect, installed Keith Coleman - the founder and CEO of Yes - as the new Vice President of Product.

Twitter's decision to install Coleman as its new VP of product is a crucial move because the post has been lying vacant for almost one year. Twitter has been without a full-time product chief since January 2016, after the departure of the company's longtime executive Kevin Weil, who left Twitter to spearhead product for Facebook-owned photo-sharing app, Instagram.

In the absence of a full-time product chief since Weil's departure, Twitter's technology chief Adam Messinger has been overseeing product till now.

With Coleman having been installed as the new VP of Product, Twitter has now got its sixth product chief since 2007, and the fourth one since the announcement of an initial public offering by the company in November 2013.

Before founding Yes -- a little-known company which has made apps like event-planning service Frenzy -- two years back, Coleman was working with tech giant Google, where he was overseeing the company's products like Gmail, Inbox and Gchat.

Soil poised to make global warming much worse: researchers find

US News - Thu, 12/01/2016 - 09:11

Soil, which is a massive repository of carbon because of plants that have grown and died in it, is poised to make the problem of global warming much worse, a new study cautioned.

Over the vast time periods, plants pull in carbon dioxide (CO2) from the air through a process called photosynthesis and use it for their growth. As warming is on the increase, the microorganisms living in the soil could naturally increase their rate of respiration, releasing CO2 or methane.

As CO2 and methane are greenhouse gases, their release into Earth's atmosphere will boost global warming. The feedback came form a fresh analysis of various previous studies.

The researchers reported, "Our analysis provides empirical support for the long-held concern that rising temperatures stimulate the loss of soil C to the atmosphere, driving a positive land C-climate feedback that could accelerate planetary warming over the twenty-first century."

Researcher Thomas Crowther, of the Netherlands Institute of Ecology, said the global perspective suggested that there is a feedback and it is actually going to be massive.

The alarming findings of the new study were published Wednesday in the influential journal Nature.

Rate of Alzheimer’s among older people declines

US News - Wed, 11/30/2016 - 10:01

The rate of Alzheimer's disease and other forms of dementia among 65 adults ages and older notably declined from in the twelve years to 2012, a new study suggested.

Conducted by University of Michigan researchers, the new study showed that the rate of Alzheimer's disease and other dementias among older people dropped from12 per cent in 2000 to around 9 per cent in 2012.

The results of the study are in line with those of some pervious studies that had also reported declines in dementia rates.

The researchers also noted that older adults with the most schooling had the lowest rates of dementia, and that the average level of education increased during the years of the study, which was reported in the most recent edition of the JAMA Internal Medicine.

Alzheimer's is disease is a progressive disease that destroys brain cell connections, gradually destroys memory and other imperative mental functions. It can last for years or lifelong.

Main symptoms of the disease include memory loss and confusion. Currently there is no cure for the condition, but medications and management strategies can temporarily help ease the symptoms.

Internet Archive plans to create copy of its archives in Canada

US News - Wed, 11/30/2016 - 08:02

In a blog post published on Tuesday, San Francisco non-profit organization the Internet Archive - a leading Internet organization which maintains one of biggest libraries of cached websites in the world - said that it plans to create a backup of its database in Canada.

The move by the Internet Archive about building a backup site in Canada is a consequence of the election of Donald Trump as the new US President.

In disclosing its decision to create a copy of its archives in Canada, a move which will cost millions of dollars, the Internet Archive said that open internet could likely be threatened by Trump, who will be sworn in as the next US President in January 2017.

By creating a database backup in Canada, the Internet Archive -- which is soliciting donations -- will essentially be able to ensure that a copy of its archives is out of the reach of the incoming US government.

About its decision to build a backup of its database in Canada, the Internet Archive said in its blog post: "On November 9th in America, we woke up to a new administration promising radical change. It was a firm reminder that institutions like ours, built for the long-term, need to design for change."
