Fruit flies adjust their courtship song based on distance

Science Daily - Wed, 03/02/2016 - 6:44pm
Outside of humans, the ability to adjust the intensity of acoustic signals with distance has only been identified in songbirds. New research now demonstrates that the male fruit fly also displays this complex behavior during courtship, adjusting the amplitude of his song depending on how far away he is from a female. Studying this process can help shed light on the building blocks for social interactions across the animal kingdom.

Receiving Real-Time Imagery From Russia's Meteor-M N2 Satellite

Slashdot - Wed, 03/02/2016 - 6:37pm
An anonymous reader writes: The Meteor-M N2 is a low orbit Russian weather satellite which broadcasts live weather satellite images, similar to the APT images produced by the NOAA satellites. But Meteor digital images are however much better as they are transmitted as a digital signal with an image resolution 12x greater than the aging analog NOAA APT signals. Radio enthusiasts are receiving images with hacked cheap digital TV dongles. There is even the AMIGOS project which stands for Amateur Meteor Images Global Observation System: users around the world can contribute Meteor images through the internet to create worldwide real-time coverage.

Elon Musk Cancels Stewart Alsop's Tesla Order Over Complaints About Launch Event

Slashdot - Wed, 03/02/2016 - 5:56pm
New submitter umafuckit writes: Blogger Stewart Alsop wrote an open letter to Elon Musk following a supposedly badly run launch event for the Model X. Alsop complained that the event started almost 2 hours late and was unable to test drive the car (for which has put down a deposit). In response, Musk cancelled Alsop's pre-order saying "Must be a slow news day if denying service to a super rude customer gets this much attention." Alsop, who is known not just for his prolific blogging but for his role as a founding partner at VC firm Alsop Louie Partners, compares his treatment by Tesla to that of BMW, about which he's also said some unflattering things as a customer.

Open Source Pioneer Michael Tiemann On the Myth of the Average

Slashdot - Wed, 03/02/2016 - 5:13pm
StewBeans writes: In a recent article, Michael Tiemann, one of the world's first open source entrepreneurs and VP of Open Source Affairs at Red Hat, highlights an example from the 1950s US Air Force where the "myth of the average resulted in a generation of planes that almost no pilots could reliably fly, and which killed as many as 17 pilots in a single day." He uses this example to argue that IT leaders who think that playing it safe means being as average as possible in order to avoid risks (i.e. "Buy what others are buying. Deploy what others are deploying. Manage what others are managing.") may be making IT procurement and strategy decisions based on flawed data. Instead, Tiemann says that IT leaders should understand elements of differentiation that are most valuable, and then adopt the standards that exploit them. "Don't aim for average: it may not exist. Aim for optimal, and use the power of open source to achieve what uniquely benefits your organization."

Location may be key to effectively controlling pain

Science Daily - Wed, 03/02/2016 - 4:10pm
In real estate, location is key. It now seems the same concept holds true when it comes to stopping pain. New research indicates that the location of receptors that transmit pain signals is important in how big or small a pain signal will be -- and therefore how effectively drugs can block those signals.

Science Daily - Wed, 03/02/2016 - 4:09pm
Not only is the 'Jupiter as shield' concept, implying that the planet shields Earth from comet impacts, not true, but perhaps Jupiter's most important role in fostering the development of life on Earth was just the opposite -- delivering the volatile materials from the outer Solar System needed for life to form. This new simulation study, and the previously underestimated role that Saturn may have also played in the evolution of life on Earth.
