From 1976 onwards, marine scientist Marianne Riedman, together with her colleague Burney Le Boeuf, studied adoption among the seals oe and why it was happening.
it's easy for elephant seal pups to get separated from their parents (Frans Lanting/Mint images/SPL) The researchers counted a total of 572 orphaned pups over the course of the four consecutive breeding seasons.
Some adult elephant seals are more likely to adopt a pup than others (Frans Lanting/Mint images/SPL) Elephant seal pups aren't the only ones to win adoptive parents either.
then they could also receive more food by more easily outcompeting smaller adoptive siblings. But why would the adoptive parents allow the intruder into their nest
White storks allow baby intruders to share their nest and food-but why?(Thinkstock) Given such high risks for adoption, why hasn't evolution endowed these birds with a better ability to identify oe and reject oe intruders?
they didn't need to give up too much of their own food so that it might survive. A female capuchin would barely notice a tiny marmoset clinging to her fur,

Astronaut food: Can you cook fries in space? If humans ever voyage to a planet far bigger than Earth,
the journey is sure to be arduous and full of danger. But there's a consolation: french fries cooked at the planet's surface will be crispier.
Preparing food in space presents unique challenges. Apart from the obvious difficulties of floating crumbs
liquids and peelings, the basic physics of cooking is different. For example, in zero gravity there's no convection in hot fluids to redistribute the heat,
Preparing drinks like percolated coffee is a challenge, because there's no gravity to pull the water down through the granules.
plenty of thought has gone already into methods of improving food preparation in space, to enhance tastiness
Fully sealed food preparation units have been proposed that dispense with the need for a human chef to do any chopping
Still, astronauts sometimes lament the drabness of their pre-prepared space meals, and have expressed even cravings for fries.
In their initial experiments, they decided to cook in increased gravity rather than zero gravity,
because they want to map out the whole landscape of how gravity influences the cooking process to get some idea of the overall trends and patterns as the tug of gravity changes.
The rate at which foods heat up in water or oil is affected by the way hot liquid circulates.
Lioumbas and Karapantsios fixed a deep-fryer containing potato sticks in half a litre of hot oil onto the end of the 8m-long arms of the Large Diameter Centrifuge at the European Space Research
This could be worth knowing for the food industry, where centrifugal"flash-frying  might be worth a try.
Beethoven immediately let out a food call standard behavior for a chimpanzee. After promptly devouring the whole bunch oe chimpanzees tend not to share food,
even with their infants oe Beethoven settled down for an afternoon nap, leaving a hungry Dilly to groom him.
Dilly did not utter a food cry, as chimpanzees normally do watched, but simply as Goodall placed the banana outside on the ground.
By stifling her food call, she could keep Beethoven in the dark, none the wiser about her illicit snacking.
the apes were given a choice to ask for food either from a human who could see them clearly,
while begging for food in all but the most obvious cases. Â If chimps couldn't even understand what others could
The flaws of such experiments led evolutionary anthropologist Brian Hare to develop a more naturalistic,
which a subordinate chimp could compete for food with a more dominant chimp. Â In his experiments, Hare set up enclosures containing two chimps, one at either end.
He placed food in the centre. Thanks to well placed barriers, sometimes both chimps could see the food;
sometimes only one. Â In one instance, Hare allowed a dominant and a subordinate chimp to watch as he put food in the middle.
However, the food was obscured from the dominant one once it was placed down. Â As is typical for chimpanzees in this sort of scenario,
the subordinate all but ignored the food, leaving it for the dominant. Subordinate chimps know better than to take food from dominant group members,
just as Dilly knew not to let Beethoven catch her eating that banana. Even though the dominant couldn't see the food,
it knew where it was. Then Hare added a twist: when the dominant chimp was replaced with a second dominant who hadn't seen the food oe all she could see was opaque barriers oe the subordinate had no problem gobbling it down.
The conclusion? Chimpanzees don't just know what others see; they also know what others know.
Animal trickery  The so-called Hare task has since been adapted and modified for a wide range of animals.
A clever experiment in which rhesus monkeys could steal food either from a silent box or from a box outfitted with bells showed that they anticipated
what others would and would not hear. Another set of studies demonstrated that ravens, too, know what others do
and do not see. The food-caching corvids were more likely to hide their caches in a spot hidden from the view of others.
If while caching, they discovered a potential raider watching them, the ravens usually picked up
and tried to hide their cache elsewhere. Together, these experiments demonstrate both the ravens'gaze-following abilities and their tactical deception skills.
How about our pets? Well, researchers know dogs can be sneaky. In one experiment, dogs were instructed not to take food from boxes, a few
of which were rigged with noisy bells. Yet when a researcher wasn't looking, the dogs would steal a meal,
and would deliberately avoid the boxes with bells to avoid detection. The evidence gathered so far suggests that many clever animals are capable of deception,
and some can make basic predictions about the knowledge states of others. They can predict what others can see,
Growing food, curbing floods, cleaning airhave you ever noticed a certain similarity in public parks and back gardens in the cities of the West?
 From natural systems to deal with surface water run off and pollution to green corridors to increasing interest in urban food production,
 There are patches that provide shade and cooling, places of local food production, and corridors that connect both residents and wildlife to the surrounding native environment.

First, there's the issue of using a food for energy. Olivier Dubois, senior natural resources officer at the United nations Food

Psychologist Paul Rozin, of the University of Pennsylvania, argues that our disgust response reduces the likelihood of ingesting disease-causing microorganisms in decayed meat, faeces, vomit, or blood.

on the other hand, have used traditionally fragrances based on musks and spices. Of course humans have been masking their true odours for thousands, not just hundreds, of years.
Since failure to feed can ultimately result in dehydration or death, some researchers think that the ability to identify those odours may itself be critical in promoting feeding-related behaviours.
For example, both clementine and vanilla are reported as pleasing, but while clementine is thought of as stimulating,
vanilla apparently makes people feel more relaxed. Smell is important to various other animals too.

We are already researching ways to harvest food and energy in deeper, more remote parts of the ocean.
Built between the 1890s and 1940s, this infrastructure still sustains some nine million people with over 1. 2 billion gallons of drinking water every day.
We can make drinking water from water that's already been used by industry. For example, a new groundwater replenishment system in California's Orange county creates near distilled water from secondary wastewater after filtering
For example, at the UK's Peterborough Power station, waste water from a nearby sewage treatment plant is used instead of drinking water.

Grey water goes straight back to kitchen gardens. In 1949, the environmental scientist Aldo Leopold  wrote:"
It's soothing to drink, and at least you are getting something nutritious inside you. This remedy has been around for years in countries where milk is popular.
which could explain why people with ulcers typically experience pain a few hours after a meal.
Studies comparing coffee, tea, beer and milk found they all stimulated the secretion of acid.
Beer and milk have the greatest effect, which suggests, somewhat surprisingly, that the ph of a drink is irrelevant

while fewer than expected got better in the milk-drinking group. Milk appeared to hinder the healing process.
drinking milk is encouraged still, as it is a good source of protein and calcium. But could very large quantities of milk present a problem?
They found that heavy milk drinkers (defined as four or more glasses a day) were more likely to develop an ulcer, especially amongst the men.
But the risk was also high in those drinking large quantities of milk, despite not having symptoms,
Using butter to treat burns is an old folk remedy that has been around for centuries.

Artificial food: Incredible or inedible? Pass the salt. And the pepper. And while you're at it, the ketchup too.
They said it politely, but these were among the reactions of the two expert"tasters  who earlier this month got the first taste of a potential food of the future oe a burger grown in a laboratory.
Funded by Google cofounder Sergey Brin, the five-year project took cells from organic cows,
cultured them in a nutrient solution to develop muscle tissue, and then teased them into thin strands of meat.
To make what was barely a quarter-pounder required tens of billions of lab-grown cells and nearly 20
000 of the cultured strands. Plus egg powder, beetroot juice, breadcrumbs, salt and saffron to add texture,
flavour and colour to the otherwise white meat. And $330, 000. The result? One taste tester said it was"close to meat,
but not that juicy Â. Another described it as"like an animal protein cake Â. Commercial cultured meat is at least a decade away,
and with the backing of billionaire Brin and others, issues of taste and feel should be solvable.

The experimental buildings illustrated here often tend to be characterised by delicacy. They increasingly move from older forms of a static, rigid world into the dynamic and sensitive qualities of a living metabolism.
The earliest glazes, dating from the late fifth millennium BC and found in the Near east,
As the technology advanced, the stones were carved often exquisitely before being coated with a blue copper-based glaze to make objects now known as faience.
Because these copper glazes appear during the so-called Chalcolithic period oe the"Copper Age  that preceded the Bronze age oe it has been thought long that they were discovered as an offshoot of the smelting of copper ores such as malachite to make the metal.
The glazes are forms of copper silicate, made as copper combines with the silicate minerals in the high temperature of a kiln.
The more of it, the greener the glaze. Sometimes these copper glazes are crystalline, with regularly ordered arrays of atoms.
But they can also be glassy, meaning that the atoms are disordered rather. In fact, it seems likely that copper smelting stimulated
How exactly might a blue glaze have been made this way? Another early Egyptologist, Alfred Lucas, who worked with Howard Carter of Tutankhamun fame,
and rock salt alone covered the quartz surface with a rather pale, greenish, dull and rough coating:
not at all like ancient blue glaze. An extra ingredient oe calcium carbonate, or common chalk, which the Egyptians used as a white pigment among other things oe made all the difference,
producing a rich, shiny turquoise-blue glaze above 950c. That looked good oe but it forces one to assume that salt,
chalk and quartz all somehow got into the kiln along with the copper scale. It's not impossible,
rock salt. Matin reasoned that dried cattle dung, which contains significant amounts of both alkalis and salt (chloride), was used widely as a fuel since the beginnings of animal domestication in the eighth millennium BC.
This too produced a nice, shiny (albeit slightly paler) blue glaze. Â Of course, there's nothing that proves this was the way glazing began.
What's for dinner? For that matter, what's to eat, full stop? In a few decades time, that second question may become pressing.
Mankind's awareness of our food supplies has been heightened by massive crop failures due to millennial level floods, protracted droughts,

Collectively, these examples show the validity of growing food in the city. Not only could be they be carried out efficiently oe such as rooftop greenhouses giving much higher yields than outdoor farms oe
Urban agriculture has the potential to become so pervasive within our cities that by the year 2050 they may be able to provide its citizens with up to 50%of the food they consume.
