Who’s downloading pirated papers on sci-hub? Everyone

An exclusive look at data from the controversial web site Sci-Hub reveals that the whole world, both poor and rich, is reading pirated research papers. Source: Who’s downloading pirated papers? Everyone

Why are our planets’ poles moving? Water.

It turns out to be two factors: 1. Polar ice is melting. 2. We are storing water in different places and moving it around the planet using piping. These factors redistribute the weight of the water around the planet, making the poles wander around. We analyze space geodetic and satellite gravimetric data for the period […]

Mathematicians shocked to find pattern in ‘random’ prime numbers

So just what has got mathematicians spooked? Apart from 2 and 5, all prime numbers end in 1, 3, 7 or 9 – they have to, else they would be divisible by 2 or 5 – and each of the four endings is equally likely. But while searching through the primes, the pair noticed that […]

Crayfis: The app that turns your phone into a cosmic ray detector.

The CRAYFIS project is a novel approach to observing cosmic ray particles at the highest energies.It uses the world-wide array of existing smartphones instead of building an expensive dedicated detector. Modern smartphones contain high-resolution cameras with digital sensors which are sensitive to the particles in a cosmic ray shower. They know where they are (GPS) […]

Rabbit brain frozen completely intact – now to thaw it…

Using a combination of ultrafast chemical fixation and cryogenic storage, it is the first demonstration that near­ perfect, long­-term structural preservation of an intact mammalian brain is achievable.

MedNexus – new search engine for evidence based medical information

Navigating the sea of information available online can be daunting at best, and dangerous at worst. Our MLA (Machine Learning Algorithms) vet the clinical impact and relevance of new research. We want to cut out the noise and pseudo-science. Source: MedNexus Hopefully better than using Google!

Quantum mechanics: Put three pigeons in two holes and none of them will be in the same hole.

We show that quantum mechanics violates one of the fundamental principles of nature: If you put three particles in two boxes, necessarily two particles will end up in the same box. We find instances when three quantum particles are put in two boxes, yet no two particles are in the same box, a seemingly impossible […]

Some Rainbows Don’t Have Every Color of the Rainbow: there are 12 types

There are at least 12 kinds of rainbows, a new study reveals, and some skip a color or two. Since the 1950s, rainbow classification has been based on the size of the raindrops that create them. The bigger the drops, the more vivid the colors. Another attempt organized them by the height of the sun […]

Bionic eye will send images direct to the brain to restore sight via 500 pixel “display”

The plan is to implant up to 11 small tiles, each loaded with 43 electrodes, into areas of the brain that deal with vision. When these areas are stimulated, people report seeing flashes of light. Lowery believes that each electrode could create a dot of light that is similar to seeing one pixel. In total, […]

China ‘clone factory’ scientist eyes human replication

The Chinese scientist behind the world’s biggest cloning factory has technology advanced enough to replicate humans, he told AFP, and is only holding off for fear of the public reaction. Boyalife Group and its partners are building the giant plant in the northern Chinese port of Tianjin, where it is due to go into production […]

Corporate funding and ideological polarization about climate change

Turns out that companies have been writing information that makes US citizens not believe in climate change science. “The comprehensive data include all individual and organizational actors in the climate change countermovement (164 organizations), as well as all written and verbal texts produced by this network between 1993–2013 (40,785 texts, more than 39 million words).

NIST team proves ‘spooky action at a distance’ is really real

As described in a paper posted online and submitted to Physical Review Letters (PRL), researchers from NIST and several other institutions created pairs of identical light particles, or photons, and sent them to two different locations to be measured. Researchers showed the measured results not only were correlated, but also—by eliminating all other known options—that […]

e-skin fingertips feel texture, pressure, temperature and hear sound

The most surprising finding? “Our e-skin picked up sound better than the mic on a smartphone.” Ko says that exactly how the pressure, texture, temperature, and acoustic signals will be transmitted into the brain is his next challenge. Source: New artificial fingerprints feel texture, hear sound

‘Zeno effect’ verified, Heisenberg uncertainty principle controlled: Atoms won’t move while you watch

The researchers observed the atoms under a microscope by illuminating them with a separate imaging laser. A light microscope can’t see individual atoms, but the imaging laser causes them to fluoresce, and the microscope captured the flashes of light. When the imaging laser was off, or turned on only dimly, the atoms tunneled freely. But […]

3D-printed teeth can kill 99% of bacteria

Researchers at the University of Groningen in the Netherlands have created a process that can manufacture 3D-printed teeth and braces which are actually good for your other teeth, and dental health in general. Source: 3D-printed teeth can kill 99% of bacteria

Prosthetic hands can now feel

A 28-year-old who has been paralyzed for more than a decade as a result of a spinal cord injury has become the first person to be able to “feel” physical sensations through a prosthetic hand directly connected to his brain, and even identify which mechanical finger is being gently touched.The advance, made possible by sophisticated […]

Estimating the reproducibility of psychological science – not doing too well…

Yet again a major study looks at reproducing results (in this case only in psychological studies) and finds that the strength of the results is much lower than published. Expect this to happen for economics, political science, etc as well. Reproducibility is a defining feature of science, but the extent to which it characterizes current […]

Antibiotic Pulled From Dirt Ends 25-Year Drug Drought – Bloomberg

Scientists have discovered an antibiotic capable of fighting infections that kill hundreds of thousands of people each year, a breakthrough that could lead to the field’s first major new drug in more than a quarter-century.The experimental drug, which was isolated from a sample of New England dirt, is called teixobactin. It hasn’t yet been tested […]

Rresearchers may have stumbled upon the secret to youthful skin

Scientists at the University of B.C. searching for ways to slow the deterioration of blood vessels may have stumbled on to the key to youthful skin. While exploring the effects of the protein-degrading enzyme Granzyme B on blood vessels during heart attacks, professor David Granville couldn’t help noticing that mice engineered to lack the enzyme […]

IBM’s Watson Analytics enters public beta | ZDNet

Users of Watson Analytics feed in their own raw data, say, in the form of a spreadsheet, which the service then crunches with its own statistical analysis to highlight associations between different variables. It saves execs from needing to know how to write their own scripts or understand statistics in order to derive meaning from […]

Regrow your teeth with lasers!

We show that non-ionizing, low-power laser (LPL) treatment can instead be used as a minimally invasive tool to activate an endogenous latent growth factor complex, transforming growth factor–β1 (TGF-β1), that subsequently differentiates host stem cells to promote tissue regeneration. LPL treatment induced reactive oxygen species (ROS) in a dose-dependent manner, which, in turn, activated latent […]
