Length: 19 mins

Language: English

Release date: 08-19-16

Publisher: Scientific American

Publisher's Summary:

Roughly half a century ago, popular attention fixed on just one global population trend: sheer size. In his 1968 best seller The Population Bomb, Stanford University entomologist Paul R. Ehrlich warned that rapid population growth would outstrip production of food and other resources, with hundreds of millions dying of famine. Ehrlichs fears were not realized, however. The green revolution soon improved food security, and a mixture of economic development and access to education and family planning brought down birth rates in much of the world. By 1970 annual population growth had begun to decline from its 1960s peak of 2 percent.

"A Tale of Two Worlds" is from the September 2016 issue of Scientific American.

Title: Honey Hunters Ask Birds for Help

Publisher: Science News

Publisher's Summary:

When asked the right way, a savvy bird species steers African hunter-gatherers to honey. All it takes is a loud trill followed by a grunt that sounds like brrr-hm." Birds known as greater honeyguides lead hunter-gatherers in Mozambique to honey-rich bees nests after hearing humans make this signature call, say evolutionary ecologist Claire Spottiswoode of the University of Cambridge and colleagues. In exchange, the birds get human-aided access to perilous-to-reach food.

"Honey Hunters Ask Birds for Help" is from the August 20, 2016 issue of Science News.

Title: Big Dreams for Small SPIDER Scope

Format: Unabridged

Length: 13 mins

Language: English

Release date: 07-27-16

Publisher: Science News

Genres: Science & Technology, Magazine & Radio

Publisher's Summary:

In the space business, weight and size are what run up the bills. So imagine the appeal of a telescope thats a tenth to as little as a hundredth as heavy, bulky and power hungry as the conventional instruments that NASA and other government agencies now send into space. Especially alluring is the notion of marrying the time-tested technology called interferometry, used in traditional observatories, with the new industrial field of photonics and its almost unimaginably tiny optical circuits. Say hello to SPIDER, or Segmented Planar Imaging Detector for Electro-optical Reconnaissance.

"Big Dreams for Small SPIDER Scope" is from the August 6, 2016 issue of Science News.

Title: Falling through Earth Would Be a Drag

Length: 3 mins

Language: English

Release date: 07-27-16

Publisher: Science News

Genres: Science & Technology, Magazine & Radio

Publisher's Summary:

Falling down a hole through the center of the Earth would be rough - especially if theres friction. A new study reveals what would happen to an intrepid traveler who jumped into a hypothetical tunnel through Earth, propelled by the force of gravity but impeded by air resistance and the friction of the tunnel walls. Physicists have estimated that if you jumped into a tunnel without such forms of drag, you would reach the other side in less than an hour. But with drag, it could be over a year before you reach Earths center - and youd never make it to the other side.

"Falling through Earth Would Be a Drag" is from the August 6, 2016 issue of Science News.

Publisher's Summary:

The deep, dark ocean bottom teems with far more oases of life than once thought. Searching along the sunless seafloor where tectonic plates pull apart-regions known as spreading ridges-researchers discovered that heat-spewing hydrothermal vents are at least three to six times as abundant as previously estimated. The finding also boosts the likely number of marine ecosystems huddled around vents.
