In addition to the Cas9 protein that bacteria use to bind and snip DNA, bacteria have other Cas proteins that know where to insert that viral DNA into the CRISPR region to remember which viruses have attacked and mount a defense. A research team has discovered how these proteins -- Cas1 and Cas2 -- locate and insert the viral DNA, and it relies on the flexibility of these enzymes and the shape of the DNA.

The unique system of hydraulic control of fins discovered in tuna indicates a new role for the lymphatic system in vertebrates. This natural mechanism may inspire designs for new 'smart' control surfaces with changeable shape and stiffness for both air and underwater unmanned vehicles.

An optical imaging tool has been developed to visualize surface chemistry in real time. Researchers imaged the interfacial chemistry in the microscopically confined geometry of a simple glass micro-capillary. The glass is covered with hydroxyl (-OH) groups that can lose a proton -- a much-studied chemical reaction that is important in geology, chemistry and technology. A 100-micron long capillary displayed a remarkable spread in surface OH bond dissociation constant of a factor of a billion.

New research has identified the culprit behind the wiring problems in the brains of people with schizophrenia. When researchers transplanted human brain cells generated from individuals diagnosed with childhood-onset schizophrenia into mice, the animal's nerve cell networks did not mature properly and the mice exhibited the same anti-social and anxious behaviors seen in people with the disease.

Genetic mutations in BRCA1 and BRCA2 increase the risk of breast and ovarian cancer in Ashkenazi Jewish women. A new article pexamines the likelihood of carrying another cancer-predisposing mutation in BRCA1, BRCA2 or another breast cancer gene among women of Ashkenazi Jewish ancestry with breast cancer who do not carry one of the founder mutations.

Every day, humans pick up on idiosyncrasies such as slow drawls, high-pitched squeaks, or hints of accents to put names to voices from afar. This ability may not be as unique as once thought, researchers report. They find that unlike all other non-human mammals, northern elephant seal males consider the spacing and timing of vocal pulses in addition to vocal tones when identifying the calls of their rivals.

Drug-related deaths among middle-aged white men increased more than 25-fold between 1980 and 2014, with the bulk of that spike occurring since the mid-1990s when addictive prescription opioids became broadly available, according to new research.

In a discovery that concludes an 80-year quest, researchers found evidence of particles that are their own antiparticles. These 'Majorana fermions' could one day help make quantum computers more robust.

A new study suggests that paying people to conserve their trees could be a highly cost-effective way to reduce deforestation and carbon emissions and should be a key part of the global strategy to fight climate change. The study sought to evaluate how effective 'Payments for Ecosystems' (PES) is at reducing deforestation.

Instead of having more children, a grandmother may pass on her genes more successfully by using her cognitive abilities to directly or indirectly aid her existing children and grandchildren. Such an advantage could have driven the evolution of menopause in humans.

A new analysis suggests that much of the carbon released from volcanic arcs, chains of volcanoes that arise along the tectonic plates of a subduction zone, comes from remobilizing limestone reservoirs in the Earth's crust.

Can somebody update me on the present legal status in the US of graphical user interfaces as intellectual property? Am I correct in believing they can't be patented (though the code can be copyrighted)?

What I really want to know: Can I rip off GVoice's old/retired web interface legally? Or more accurately, can I pay somebody else to do it for me with reasonable ability to assure them they won't go to jail or get sued into oblivion for doing it?

To be clear, there are some nifty functional subtleties I'd want to make off with, which I wouldn't even want to bother pretending I came up with on my own. For instance, there's some interesting algorithm for how texts are batched into threads which I haven't entirely reversed engineered, but make a huge difference in readability.
