6:29 PM | Emotion Recognition Software
Facial recognition software works pretty well. It measures various parameters, such as the distance between the person's eyes, the height from lip to top of their nose and various other metrics and then compares it with photos of people in a database. Why not create emotion recognition software that can use its own custom parameters?  Dev Drume Agrawal, Shiv Ram Dubey and Anand Singh Jalal of the GLA University, in Mathura suggest in the International Journal of Computational Vision and […]

6:07 PM | It's Flagella Against The Cantilever For The Fate Of Bacteria
A team of researchers has developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony. The researchers chemically attached colonies of Escherichia coli bacteria to a microcantilever – a microscopic beam anchored at one end, similar to a diving board – thus coupling its motion to that of the bacteria. As the cantilever itself isn't doesn't generate any vibrations, or 'noise,' this […]

5:44 PM | A Brief Guide to the Twenty Common Amino Acids
The proteins that make up living organisms are huge molecules, but they’re composed of tinier building blocks, known as amino acids. There are over 500 amino acids found in nature, yet, of these, the human genetic code only directly codes for 20. Every protein in your body is made up of some linked combination of these amino […]

5:14 PM | Now you can work in your sleep
When people practice simple word classification tasks before nodding off—knowing that a "cat" is an animal or that "flipu" isn't found in the dictionary, for example—their brains will unconsciously continue to make those classifications even in sleep. The findings, reported in the Cell Press journal Current Biology on September 11, show that some parts of the brain behave similarly whether we are asleep or awake and pave the way for further studies on the processing […]

5:07 PM | Study offers clues to how breast implants may cause lymphoma
Researchers at the University of Cambridge, together with colleagues specialising in plastic surgery or histopathology in Austria, Australia, Liverpool and Swansea, have identified clues to explain how breast implants may, on very rare occasions, contribute to the development of lymphoma.

4:59 PM | Smarter mice with a “humanized” gene?
In­tro­duc­ing a “hu­man­ized” ver­sion of a lan­guage-linked gene in­to mice ac­cel­er­ates their learn­ing, ac­cord­ing to a stu­dy. The gene, called Foxp2, is of a type known as tran­scrip­tion fac­tor—a gene that con­trols the ac­ti­vity of oth­er genes. It has al­so been linked to the de­vel­op­ment of hu­man speech and lan­guage. The gene is found in […]

4:53 PM | What can evolutionary biology learn from creationists?
You might expect a professional evolutionary biologist like myself to claim that my discipline has nothing to learn from creationists. And I certainly do find all flavors of evolution-denialism sadly misguided. But I also find it reasonable to assume that any serious and dedicated critic should uncover something interesting about the object of their obsession. Subject:  Atheism & Religion

4:41 PM | If hippopotamuses can't swim, how can some be living on islands?
There is no published account where hippopotamuses are demonstrably shown swimming or floating at the surface of any body of water. But if they can't swim, how did they reach and colonize islands? Experts say that widely accepted models for the methods, patterns, and timing of the colonization and dispersal to several islands (e.g., Cyprus, Crete, and Madagascar) may need to be reconsidered.

4:33 PM | Artificial intelligence is doomed if we don't control our data
Machine learning is what's taking place with our personal data while we're passive players in the process. Personalization algorithms designed to know our intentions before we do form the backbone of the Internet Economy. And while these algorithmic systems may not fit all the criteria of genuine Artificial Intelligence (AI), their artifice is firmly in place in terms of their bias. Advertising-based AI frames our lives within purchase funnels, where our desires are only relevant in […]

4:18 PM | Early Earth less hellish than previously thought
Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates. This alternate view of Earth's first geologic eon, called the Hadean, has gained substantial new support from the first detailed comparison of zircon crystals that formed more than 4 billion years ago with those formed contemporaneously in Iceland, which has been proposed as a possible geological analog […]

4:16 PM | ‘Eskimo1′ gene helps plants survive drought conditions
Genetic modification (GM) has been a hot topic for the past couple of decades, and with scaremongering over ‘Frankenstein foods’ you’d be forgiven for thinking that GM is only being used to produce horrifying steroid-addled mutant plants, which will one day develop a taste for human flesh and take over the Earth (like in Day…

3:41 PM | Wild Mushrooms: You May Eat Something Even Science Doesn't Know About
For lovers of wild foods, autumn means things like mushrooms and fungi of dizzying variety. Intrepid treasure hunters scour the woods in search of delectable wild mushrooms and their not-quite-meat, not-quite-vegetable qualities. A bonus: If you find some, you may be eating something not even known to science. The Fungi Kingdom is enormously diverse and completely under-documented. Species are tough to know, and that is without counting the billions that have gone extinct without us ever […]

2:26 PM | Wearable Computing And Privacy Invasions You Might Want To Think About Now
You lookin’ at me?Gareth Fuller/PABy Tom Foulsham, University of EssexAre you being recorded? Thanks to the ubiquity of CCTV and camera phones, the answer is more than ever before likely to be “Yes”. Add to this the growth of wearable technology such as Google Glass and people are increasingly exposed to devices that can monitor and record them, whether they realize it or not. read more

1:44 PM | The U.S. Is Committing 3,000 Troops and Half A Billion Dollars to Stop the Spread of Ebola
Later today, President Barack Obama will announce the United States’ new plan for stemming the spread of the Ebola virus in Africa. As of September 7, there were 4,366 confirmed, suspected or probable cases, as well as 2,218 deaths. The real numbers are probably much higher though, since many suffering from the disease in rural parts of Africa are actively avoiding detection. The President will announce his plans during a visit to the Centers for Disease Control and Prevention […]

Of all the quacks and cranks and purveyors of woo whom I’ve encountered over the years, Deepak Chopra is, without a doubt, one of the most arrogantly obstinate, if not the most arrogantly obstinate. Sure, a quack like Mike Adams wins on sheer obnoxiousness and for the sheer breadth of crankery to which he ascribes,…

By Marsha Lewis, Inside Science(Inside Science TV) – One of the deadliest forces on earth is the humble mosquito. Mosquito-borne diseases like malaria, chikungunya, yellow fever and West Nile virus infect more than 350 million people and kill another 1 million people every year.Now, scientists in Florida hope to wipe out some of these deadly diseases by genetically modifying their winged carriers.“Mosquitoes are probably the most dangerous animal in the world. More people are killed […]

12:00 PM | Pseudouridine: RNA Modifications In Some Unexpected Places
That DNA makes RNA which makes protein is a simplified explanation molecular biologists use to explain for how genetic information is deciphered and translated in living organisms. The process is more complicated than the schema first articulated nearly 60 years ago by Nobel Laureate Francis Crick, co-discoverer of the DNA's double-helix structure. Now it is known that there are multiple types of RNA, three of which—messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA […]

James Stuart thought he was better than you. This isn’t a base slander on my part, this was his honest academic opinion.
