Camera DIY Solar Filter [Photography]

Camera DIY Solar FilterIf you're interested in solar photography you can make a DIY solar filter using old CDs, cardboard, glue, and tape. As long as you're not looking directly through the lens but instead using the LCD screen you don't have to worry about damaging your vision.

Instructables user Analogue-Chick also points out that while this method isn't dangerous for your vision you may damage your camera so be sure to use this with your five-year-old POS camera you still have around for backup not your prized DSLR.

First of all you'll need to make sure that your camera's lens can be completely covered by a piece of reflective material from a CD. Measure this and if the sizing works you'll want to pry off half the polycarbonate plastic that covers the reflective layer of the CD. You'll then cut out an eyepiece from cardboard with an aperture the same size as your lens and glue the circle of reflective material you cut from the CD inside the eyepiece. Make a cylinder out of cardboard and cover that with electrical tape to prevent light transmission.

Now you'll just need to place the filter over your camera lens and you're ready to go. You'll want to first test out the filter by photographic a light bulb and remember, you're never going to look through the viewfinder to photograph the sun you're only going to use the LCD screen. See sample photos using this filter at the source link below.

Potentially dangerous new malaria mosquito identified

ScienceDaily (Sep. 28, 2012) ? University of Notre Dame entomologists are part of a team of researchers that recently discovered a potentially dangerous new malaria-transmitting mosquito. The as yet unnamed, and previously unreported, mosquito breeds in the western areas of Kenya and has an unknown DNA match to any of the existing malaria-transmitting species.

The Anopheles species of mosquitoes which transmits malaria in Africa is already widely studied by researchers. It prefers to rest indoors during the day and feed on humans during the night. Current malaria control programs, including spraying of insecticides and using insecticide-treated bed nets, are designed with these behaviors in mind.

Although the new species has never been implicated in the transmission of malaria, new discoveries in its biting habits pose a threat because it was found to be active outdoors and prefers to bite people earlier in the evening, soon after sunset, when people are not protected by current malaria control techniques.

Neil Lobo, a Notre Dame research associate professor and Brandy St. Laurent, a former Notre Dame doctoral student, joined forces on the team of researchers that made the discovery. y Frank Collins, Notre Dame's George and Winifred Clark Professor of Biology, Collins was principal investigator of the Malaria Transmission Consortium effort funded by the Bill & Melinda Gates Foundation.

The discovery was announced in a paper whose lead author was Jennifer Stevenson of the London School of Hygiene and Tropical Medicine.
