Range Rover revamps the Evoque line-up: now wet grass capable

Land Rovers throwing the spotlight back on its fixed-roof Evoque, following the launch of the Evoque Convertible, by offering a range of updates for the 2016 model year. So, whats this red and black colour scheme about?.

Thats the new Ember edition of the Evoque. Its based on an HSE Dynamic model and features a bespoke colour scheme and details, consisting of Firenze Red and Santorini Black highlights. .

Inside, youll find black seats with contrasting red stitching, black and red mats and gloss black trims. The Range Rover Evoque Ember also features the Black Pack, so comes with black 20-in wheels, black tailpipe trims, a black grille and darkened lights. .

The Ember edition is only going to be available for a three-month period and, if youre interested, youll pay £47,200 for the premium. Deliveries begin in September. Youll forgive us if we dont get out our debit cards right this very moment.

Perhaps the technical updates are more notable?.

Firstly, the new InControl Touch Pro media system is now available in the regular Evoque. Its a far slicker, modern-looking affair and features a 10.2-in touchscreen display, sat-nav and a range of route and planning functions. .

The new system – which is currently offered in the Evoque Convertible, among other JLR products – will be standard on HSE Dynamic, HSE Dynamic Lux and Autobiography trims.

Elsewhere, buyers of the lower-spec SE Tech Evoque will now benefit from 12-way electric seats and automatic high beam assist.

HSE Dynamic trims and above will get the 10.2-in InControl Touch Pro system, and automatic versions will now come with JLRs All Terrain Progress Control.

Its basically off-road cruise control, so you just set your speed and concentrate on driving over the kerb. Whats all this about messing around on grass?.

Apparently dropping the Evoque into first gear, releasing the brake and then gently applying some throttle proves too troublesome for some drivers. So, Land Rovers seen fit to roll out a new Low Traction Launch mode.

It aims to automatically deliver the maximum amount of torque possible on slick surfaces, allowing the driver to make a painless, simple getaway.

Reputedly, no precise throttle control is required; you simply squeeze the pedal and the onboard electronics will work to put the power down where and when they can, without cutting back so excessively that you stop moving entirely.

What else is new to the range?. If youre not sold on the likes of the Black Pack, then perhaps the new Graphite Design Pack – for Autobiography models – will be more to your liking.

As you can probably guess, it adds a host of grey details – including a grey grille, satin grey wheels and grey towing eye covers. Contrasting black details elsewhere complete the look. For that, you can expect to fork out £2125.

Land Rover has also added a host of new exterior colours, bringing the total line-up to 18. Thatll further improve your chances of distinguishing your new Evoque a little from the 520,000 that have been sold since 2011.

The Poison Squads: The Stupid, Risky First Food Safety Tests - Duration: 5:18.

[♪♩INTRO]

I think we can all agree that food… is pretty great.

So participating in an experiment where almost all you have to do is eat three delicious

meals every day for up to a year sounds kind of like the dream.

But imagine knowing that hidden in one of the foods—maybe the butter, maybe the

freshly picked peas—is a substance that's probably toxic.

It sounds unthinkable today, but that was the setup of some of the strangest and most

infamous human experiments in American history, known as the poison squads.

They ran for five years starting in 1902.

And even though they wouldn't pass any scientific ethics committee today, they were revolutionary

at the time because people started to realize that maybe they should make sure things are

safe to eat before eating them.

The trials were the brainchild of Harvey Washington Wiley, the head chemist with the U.S. Department

of Agriculture.

Back then, food additives didn't have to be tested, or even put on labels, and he wasn't

really okay with the idea that no one in America had any way of knowing what they were actually

eating unless they had grown or raised it themselves.

Formaldehyde, for example, regularly popped up in milk to keep it from souring.

Yeah, the known carcinogen that we use to preserve dead bodies.

You'd also often find borax, a mineral that contains sodium and boron, in meat.

It made the meat firmer, which made it seem fresher — especially when combined with

an extra pinch of salt and red food coloring.

These days borax is a common ingredient in things like detergent and pesticides.

And we're not talking tiny, insignificant amounts of this stuff, either.

But no one had bothered to investigate whether these additives were actually safe to eat.

So, with five thousand bucks from the government, Wiley hired a chef, promised a bunch of otherwise

great free food, and recruited a dozen healthy young men as volunteers.

He took their weight and vitals, made them collect their urine and feces, and gave them

weekly physicals.

Then, they started with a low dose of a specific chemical and went up, stopping only when the

men were too sick to continue.

The first poison squad tackled borax and its derivative, boric acid, because they were

so common.

At first, the chef hid the chemicals in butter or milk.

But the volunteers could taste the metallic flavor and instinctively avoided it, because

no one wants to eat butter that tastes like their silverware.

Wiley still needed the men to get the right dosage, so he just put the borax in pills

for them to pop about halfway through their meals.

Bon appetit!

The guys on the Poison Squad reported stomach pains and feeling less hungry when they were

fed 2-3 grams of borax a day.

At 4 grams, they became very tired, developed headaches, and couldn't work normally.

Which sounds like an average Monday to me, but apparently in their case it was caused

by the borax.

Through other trials, Wiley also found that if they took a lower dose of half a gram a

day for long enough, they'd get similar symptoms.

Today we know that eating borax can cause tissue damage, which can eventually lead to

fun things like vomiting and convulsions, so thanks for saving us from that one, Poison

Squad.

Thankfully, though, almost no one walked away from these experiments with any obvious long-term

problems.

Wiley also tested copper sulfate, which was added to things like canned peas to make them

bright green, as well as formaldehyde, sodium benzoate, and salicylic acid.

While the effects on the men varied, Wiley concluded that none of the additives were

safe.

Today, any scientist looking back at these trials would be horrified by not only the

ethical problems -- because giving people potentially deadly substances, even if they

know about them, is never OK -- but also the poor experimental design.

For one thing, the participants knew they were eating a potential poison, which could

have easily skewed the symptoms they reported and made them feel more sick than they actually

were.

Not to mention that for the most part, the experiment had no real control group.

In between testing each substance, the squads were given a break for several weeks, but

they weren't asked to continue reporting symptoms or to keep collecting their urine

or fecal samples.

You also can't really conclude much from a small and specific group of people.

Wiley thought that if healthy young men got sick, the same chemical would also be unsafe

for women and children.

That's not really how biology works, though, and a few dozen young white guys didn't

exactly represent all of America.

But even though there were a lot of flaws with this experiment, it was the first time

somebody thought to test food additives and study them one at a time.

Later research that was actually reliable led to almost all of these additives being

banned from food -- except for sodium benzoate, which is a common preservative in acidic foods,

like orange juice and soda.

But only because we've tested it and it's considered safe.

And journalists loved covering the happenings in the D.C. lab kitchen, so people across

the country started thinking seriously about the things that might be used to preserve

their food.

In 1906, partly because of the public's new awareness, Congress passed the Pure Food

and Drug Act, a precursor to today's more rigorous regulations.

Those concerns also led to the creation of the FDA, which is the organization that makes

sure the ingredients in your food aren't going to kill you.

For the most part, anyway.

If you decide to crack open ten thousand cans of baked beans, there's not much they can

do to help.

That one's on you.

Since Wiley was so instrumental in protecting America's food, he's often called the

father of the agency.

So, the Poison Squads were a really horrible idea and full of sketchy science.

But because of the progress we've made since then, going to the supermarket today is a

whole lot safer.
