UK Gov't Launches Anti-Adblocking Initiative, Compares It To Piracy

Slashdot - Wed, 02/03/2016 - 5:54pm
An anonymous reader writes: UK culture secretary John Whittingdale has announced that the British government will set up a 'round-table' between online publishers and adblocking companies to discuss the 'problem' of adblocking. He described the practice of charging companies to be whitelisted as a 'modern day protection racket', and said: "Quite simply – if people don't pay in some way for content, then that content will eventually no longer exist And that's as true for the latest piece of journalism as it is for the new album from Muse." The issue has largely been left to the market to self-regulate until now, although Germany's courts ruled adblocking legal in 2015.

Metamaterial separation proposed for chemical, biomolecular uses

Science Daily - Wed, 02/03/2016 - 5:15pm
The unique properties of metamaterials have been used to cloak objects from light, and to hide them from vibration, pressure waves and heat. Now, a researcher wants to add another use for metamaterials: creating a new directional separation technique that cloaks one compound while concentrating the other.

LibreSSL Unaffected By DROWN

Slashdot - Wed, 02/03/2016 - 5:15pm
serviscope_minor writes: The OpenBSD people forked and heavily cleaned up OpenSSL to create LibreSSL due to dissatisfaction with the maintainance of OpenSSL, culminating in the heartbleed bug. The emphasis has been on cleaning up the code and improving security, which includes removing things such as SSL2 which has fundamental security flaws. As a result, LibreSSL is not affected by the DROWN bug. LibreSSL is largely compatible with OpenSSL. The main exceptions are in the cases where programs use insecure functions removed from libreSSL, or require bug compatiblity with OpenSSL.

State laws boost flu vaccination rates in health care workers

Science Daily - Wed, 02/03/2016 - 5:13pm
State laws mandating influenza immunization for people who work in health care increase their vaccination rates, according to new research. From 2000 to 2005, only Maine and New Hampshire had flu vaccine requirement laws for health care workers. During that period, the average flu vaccination rate for health care workers was 22.5 percent. From 2006 to 2011--when 19 other states, including Pennsylvania, passed similar laws--the average vaccination rate for health care workers increased to 50.9 percent.

Carbon nanotubes improve metal's longevity under radiation

Science Daily - Wed, 02/03/2016 - 5:12pm
Carbon nanotubes may improve longevity in nuclear reactors, report scientists. For now, the method has only proved effective for aluminum, which limits its applications to the lower-temperature environments found in research reactors. But the team says the method may also be usable in the higher-temperature alloys used in commercial reactors.

Molecular architectures see the light

Science Daily - Wed, 02/03/2016 - 5:12pm
Organic photovoltaics bear great potential for large-scale, cost-effective solar power generation. One challenge to be surmounted is the poor ordering of the thin layers on top of the electrodes. Utilizing self-assembly on atomically flat, transparent substrates, a team of scientists has engineered ordered monolayers of molecular networks with photovoltaic responses. The findings open up intriguing possibilities for the bottom-up fabrication of optoelectronic devices with molecular precision.

Some bacterial CRISPRs can snip RNA, too

Science Daily - Wed, 02/03/2016 - 5:12pm
Did you know the CRISPR/Cas9 system was derived from bacteria, which use it to fight off foreign invaders such as viruses? It allows many bacteria to snip and store segments of DNA from an invading virus, which they can then use to 'remember' and destroy DNA from similar invaders if they are encountered again. Recent work demonstrates that some bacteria also use the CRISPR/Cas system to snip and recognize segments of RNA, not just DNA.

Discovery of a gene associated with a set of poorly understood rare diseases

Science Daily - Wed, 02/03/2016 - 5:12pm
GEMC1 has been identified as a master gene for the generation of multiciliated cells -- cells with fine filaments that move fluids and substances -- which are found exclusively in the brain, respiratory tract, and reproductive system. Defects in multiciliated cells lead to ciliopathies -- rare and complex diseases that are poorly understood and for which not all causative genes have been identified.

Homeschooled kids sleep more than others, study shows

Science Daily - Wed, 02/03/2016 - 5:12pm
Teens who are homeschooled benefit from healthier sleep habits than those who go to most private and public schools, a new study has concluded, the first of its kind. The findings provide additional evidence of teens' altered biological clocks and support an argument for starting traditional high school later in the morning.
