Chemical Turing Test: Making Artificial Cells Talk With Real Ones

Science2.0 - January 25, 2017 - 5:13pm
In computer science, the classic Turing test evaluates a machine's ability to mimic human behavior, and therefore is a measure of determining how close a machine can come to artificial intelligence. To pass, a computer must fool the tester into thinking it is human -- typically through the use of questions and answers.

What about for single-celled organisms? They can't communicate with words but they still communicate, and that means the search is on to create artificial ones that do just. IN ACS Central Science, researchers demonstrate that certain artificial cells can pass a basic laboratory Turing test by 'talking' chemically with living bacterial cells.

Verlinde's Dark Universe

Science2.0 - January 25, 2017 - 4:49pm

Lots of people have asked me for my views on Erik Verlinde’s latest paper “Emergent Gravity and the Dark Universe“. This fifty-one pages long preprint has attracted a fair bit of media attention. Particularly in the Netherlands, Verlinde’s name being attached to the draft paper has caused a true hype.

Will Future Songs Be About Self-Driving Cars?

Science2.0 - January 25, 2017 - 11:34am
America is a car culture. The saying goes, in Europe 100 miles is a long distance whereas in America 100 years is a long time.

With a heritage of continental exploration and frontier expansion, it is no surprise that Americans embraced the automobile in a way no one else did. It inhabits our movies, our music. Everyone except millennials has a road trip soundtrack. Life is a highway, Route 66, and more.

For Healthy Babies, Baby Monitors Have No Benefit

Science2.0 - January 24, 2017 - 10:43pm
Expectant and new parents are under a great deal of pressure; every action is scrutinized by those around them, and food marketers and activist groups exploit their fear by telling them one food process will lead to higher grades in school while another food process will lead to obesity, cancer, endocrine disruption and anything else environmental fundraisers can dream up.

It takes no time to make such claims and exploit people for money but far longer to do studies to show if the claims are real.

Coffee May Be That Fountain Of Youth

Science2.0 - January 24, 2017 - 9:19pm
A chronic inflammatory process that may trigger cardiovascular problems could be solved by what's in a cup of coffee, according to a recent paper.

Using survey data, medical and family histories and blood samples of over 100 human participants in the Stanford-Ellison cohort, a long-term program begun 10 years to study the immunology of aging(1), has revealed a fundamental inflammatory mechanism associated with human aging and implicates this inflammatory process as a driver of cardiovascular disease and increased rates of mortality overall. Metabolites, or breakdown products, of nucleic acids — the molecules that serve as building blocks for our genes — circulating in the blood can trigger this inflammatory process, the study found.

School Comparisons Tell Us Little About School Performance

Science2.0 - January 23, 2017 - 12:39pm

The latest performance tables for secondary and primary schools in England have been released – with parents and educators alike looking to the tables to understand and compare schools in their area.

Schools will also be keen to see if they have met a new set of national standards set by the government. These new standards now include “progress” measures, which are a type of “value-added measure”. These compare pupils’ results with other pupils who got the same exam scores as them at the end of primary school.

Scientists And Philosophers For Donald Trump: Let Master Feng Explain The New Reality To You

Science2.0 - January 23, 2017 - 6:45am
Ah the beauty, from victory to victory for over a year now – is it not wonderful to be alive today? For those few of us who have for years predicted the current affairs, 2016 was so refreshing also because it ensured that 2017 goes on giving. The Donald pulled all the ‘right’ moves to win against the lefties, who still do not understand a thing, but more important, he pulled equally ‘right’ moves against the cucked right, and against the this-is-my-career-niche right, which made it clear to some for four months in advance that Trump would win. -->

How To Stomach A Black Hole

--- repost due to previous version not surviving server maintenance ---

Black holes are hot. Well, thermodynamically these suckers are freaking cold, but they do attract more attention than hot supernovae. And with attention comes recognition. As announced last month, as much as 97% of the $ 6.3 mln 2016 Breakthrough Prize money for physics went to black hole research.

Climate Change Made The Sahara Green - Then Took It Away Again

Science2.0 - January 19, 2017 - 3:11pm
From 5,000 to 11,000 years ago, what is now the Sahara Desert had 10X the rainfall it does today and was home to hunter-gatherers who lived in the region's savannahs and wooded grasslands. By analyzing marine sediments, rainfall patterns in the Sahara during that 'Green Sahara' period have been pinpointed.

Sitting Linked To Premature Aging - And Hopefully Skepticism

Science2.0 - January 19, 2017 - 2:47pm
Elderly women who sit more than 10 hours a day have accelerated biological aging, according to an epidemiology paper. They have older cells? 

It's the increasingly popular shorter telomeres hypothesis. Telomeres are tiny caps found on the ends of DNA strands, like the plastic tips of shoelaces, that protect chromosomes from deterioration. It has been found that they progressively shorten with age, just one of the reasons why we are considered to be biologically programmed to die.

How Viruses Leave Messages For Descendants On How To 'Infect'

Science2.0 - January 18, 2017 - 9:08pm
Many viruses face a choice after they have infected their hosts: to replicate quickly, killing the cell in the process, or to become dormant and lie in wait. HIV, herpes, and a number of other human viruses behave this way and, in fact, even the viruses that attack bacteria – phages – face similar decisions when invading a cell.

What causes a virus to choose dormancy over immediate gratification? Prof. Rotem Sorek and his group in the Weizmann Institute’s Department of Molecular Genetics have now discovered that, during infection, viruses secrete small molecules into their environment that other viruses can pick up and “read.” In this way, they can actually coordinate their attack, turning simple messages into a fairly sophisticated strategy.

Debunked: World To End After Two Snowy Days In Salento, Puglia, Southern Italy, Tears On Macedonia Icon

Science2.0 - January 12, 2017 - 9:20pm

As some of you may know, I've become deeply concerned, and indeed appalled by the large numbers of fake doomsday news stories, because I am so often contacted by people who get very scared and sometimes suicidal as a result of reading these stories. Fourteen tabloids and other papers have published this story so far, and none of them mention that it originates from a site known to publish fake news. The story is that the world is going to end because of two snowy days in Salento in Southern Italy, which they say is a prophetic sign of an imminent massive supervolcano eruption. I think it is a particularly striking case of doomsday news based on chinese whispers starting off from a fake story.
