Poignant Dog Food Ad Tackles Race, Highlights What Pups Can Teach Us About Unconditional Love

Turns out our pups can teach us a lesson in being our fellow man’s best friend.An ad from dog food company Pedigree calls attention to race relations by illustrating an interaction between two pet owners.

Watch how dogs truly have no prejudices in the full commercial here. 

Seen up close, the anatomy of a mosquito bite is terrifying. The most dangerous animal in the world uses six needle-like mouthparts to saw into our skin, tap a blood vessel and sometimes leave a dangerous parting gift. NEW from @kqedscience‘s Deep Look!

We really need to talk about Boko Haram...

They haven’t been covered much in the mainstream media but Boko Haram have been terrorising Africans with devastating, widespread and long-lasting consequences.

Responsible for more deaths than ISIS

According to the Global Terrorism Report, they have overtaken ISIS as the world’s deadliest terrorist group. It should be noted that in March this year, they pledged allegiance to ISIS. The two groups are responsible for more than half of all terrorist attacks in the world.

Who are they?

Boko Haram promotes a version of Islam which makes it “haram”, or forbidden, for Muslims to take part in any political or social activity associated with Western society.

This includes voting in elections, wearing shirts and trousers or receiving a secular education.

Boko Haram regards the Nigerian state as being run by non-believers, even when the country had a Muslim president - and it has extended its military campaign by targeting neighbouring states.

800,000 people have fled their homes since June

Since the beginning of Boko Haram’s attacks in 2009, 2.1 million people have been forced to leave their homes with a staggering 800,000 having fled between June - September 2015.

An estimated 1,100 schools have been destroyed this year alone

The UN have stated that over a thousand schools have been destroyed in Cameroon, Chad, Niger and Nigeria in 2015 so far.

This is a list of their major attacks so far in 2015:

This is what a real, qualified OBGYN will tell you about what women feel when they get an abortion

Dr. Willie Parker, who is trained as a gynecologist and OBGYN, is a hero for the pro-choice movement because he’s honest about the undiscussed aspects of getting (or not getting) an abortion. Watch how he gives a consultation.

Life in Technicolor: Glasses for the colorblind

With so much of our world color-coded, life can be quite tricky without the ability to see the full range of the rainbow.

For the 13 million Americans (and 300 million people worldwide) with color vision deficiency or blindness, living with the inability to detect red, blue, green or a mixture of these colors means having to learn to discern traffic lights or subways lines based on order and patterns rather than color, or having to ask someone whether the piece of meat they’re about to ingest is actually well-done.

However, EnChroma, one of several emerging startups founded by University of California alums, is changing the way people with color vision deficiency experience the world. They make eyewear that corrects for the most common color blindness. 

According to Marc Levin, a neuro-ophthalmologist at UCSF, the lenses work by changing how light is received by the brain for those whose eyes lack sensitivity to red and green light wavelengths. It filters out light that the red and green light-absorbing molecules/photopigments in our eyes sense most similarly. This helps the brain receive more distinct color wavelength information.

While their glasses currently only work for people with red-green color blindness, the company hopes to eventually create lenses that will also help individuals with more severe color vision deficiencies.
