The frenzy over kale has turned from foodie buzz to eater roar. Around the country everyone is talking about kale. As a physician, nothing could please me more. Kale represents an important lesson for all us eaters about the power of food choices to transform our health. Sure, let’s disclose my bias right away. My new book 50 Shades of Kale (Harper/Wave 2013,) co-authored with Chef Jennifer Iserloh, is just out. It is a gorgeous tribute to our muse kale and at its core a food prescription aimed to improve your brain health.

So what’s all the kale hype about?

TAIPEI, Taiwan — A giant panda, one of a pair presented by China four years ago to mark warming ties with Taiwan, has given birth to a female cub at a Taipei zoo, officials said Sunday.

The 9-year-old Yuan Yuan delivered the cub Saturday night, following artificial insemination given in March, the zoo announced.

It was the seventh such attempt on Yuan Yuan in three years, they said. Natural pregnancy among pandas is relatively rare.

The message inside “the world’s most mysterious medieval manuscript” has eluded cryptographers, mathematicians and linguists for over a century.

And for many, the so-called Voynich book is assumed to be a hoax.

But a new study, published in the journal Plos One, suggests the manuscript may, after all, hold a genuine message.

Scientists say they found linguistic patterns they believe to be meaningful words within the text.

Plants have a built-in capacity to do maths, which helps them regulate food reserves at night, research suggests.

UK scientists say they were “amazed” to find an example of such a sophisticated arithmetic calculation in biology.

Mathematical models show that the amount of starch consumed overnight is calculated by division in a process involving leaf chemicals, a John Innes Centre team reports in e-Life journal.

Birds may use similar methods to preserve fat levels during migration.

MEXICO CITY (Reuters) – Archaeologists have found an ancient Maya city that remained hidden for centuries in the rain forests of eastern Mexico, a discovery in a remote nature reserve they hope will yield clues about how the civilization collapsed around 1,000 years ago.

The team, led by Ivan Sprajc, associate professor at the Slovenian Academy of Sciences and Arts, found 15 pyramids—including one that stands 75 feet (23 metres) tall—ball courts, plazas and tall, sculpted stone shafts called stelae.

They named the city Chactun, meaning ‘Red Rock’ or ‘Large Rock.’ Sprajc said it was likely slightly less populous than the large ancient Maya city of Tikal in Guatemala, and could have been home to as many as 30,000 or 40,000 people, though further research is necessary to determine an exact estimate.

Oscar-winning actor explains why he travelled around the world to highlight the environmental problems caused by our waste

Jeremy Irons, the Oscar-winning actor, has teamed up with the British filmmaker Candida Brady to produce a new feature-length documentary called Trashed. It sets out to “discover the extent and effects of the global waste problem, as he travels around the world to beautiful destinations tainted by pollution”.

Ahead of its first theatrical screenings in the US later this month, Irons answered my questions about the film via email…

A glimpse into one tiny nook of the UK’s vast ocean depths uncovered two drink cans, one bottle, and a rusty food tin

On 15 August 1934, two adventurers squeezed into a tiny metal capsule and became the first people to see another world. Their names were William Beebe and Otis Barton, and the world that they saw was the deep ocean, when they dived more than half a mile down in their bathysphere near Bermuda. They were the first to journey beyond the sunlit waters of the upper ocean, and Barton later commented that “no human eye had seen this part of the planet before us, this pitch-black country lighted only by the pale gleam of an occasional spiraling shrimp”.

An endangered species is set to return to a Northumberland forest more than 30 years after it was wiped out.

Conservationists at Kielder Water & Forest Park plan to reintroduce water voles to the area after they disappeared.

The animals have not been spotted in the area since the 1970s.

Forestry Commission ecologist Tom Dearnley said they were “extremely keen” to see the project go ahead at Kielder.

A new source for biodiesel is making its debut at some San Francisco gas stations. Will algae be able to prove itself as a fuel alternative?

For years we’ve been hearing about the promise of crude oil derived from algae. In theory, it sounds

like the solution to our CO2-heavy gasoline habit: Algae requires very little land to grow (significantly less than most other biofuels), it’s cheap, and it’s abundant. But algae requires a lot of water to grow and scaling up fuel projects has been difficult for a variety of logistical reasons. Nonetheless, you can now get a side of algae fuel with your petroleum if you live in the San Francisco Bay Area and drive a car with a diesel engine.

We live in a data-driven world — one where, if you care about your personal fitness, you are most likely tracking it. It wasn’t long ago that the use of pedometers, heart rate monitors and calorie counters was reserved for the borderline obs

essive. Devices such as the Nike FuelBand, Adidas miCoach and FitBit have helped simplify the use of this functionality, but they have also changed the way we approach fitness. Today, to be fit is to be data-obsessed. Working out without data just seems…primitive.

Sonny Yu, CEO and co-founder of Redwood City, Calif.-based startup Misfit Wearables, couldn’t agree more. He and his business partners found themselves fascinated by these devices. Sensing opportunity, they decided to make their own– with some notable updates.

The Best LED Lightbulb Is the Philips L-Prize

I”m replacing my old favorite LED lightbulb, the Philips 12.5 watt ambientLED, with the company”s next-generation L-prize bulb, now that its finally less than $40 ($37) online.

Philips”s next-

generation bulb is based closely on the bulb that won the $10 million government contest to create the future of lightbulbs. It”s called the L-Prize bulb, and it is more efficient at 9.7 watts (instead of 12.5 watts) than the bulb below. It”s also brighter at 940 lumens versus 800 lumens, has a much better light quality rating, and lasts 30,000 estimated hours instead of 25,000.
