    By analyzing the fossilized teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants (婴儿) for longer periods than their contemporary relatives.

    The results, published in the journal Science Advances, provide a first insight into the practice of weaning (断奶)that remain otherwise unseen in the fossil record.

    The team sampled minute amounts from nearly 40 fossilized teeth of our South African fossil relatives, early Homo, Paranthropus robustus and Australopithecus africanus. They measured the proportions of their stable calcium isotopes (同位素)in the tooth enamel(牙釉质), which are a function of the mother milk intake by infants. They show that early Homo offspring(后代) was breastfed in significant proportions until the age of around three to four years, which likely played a role in the apparition of traits that are specific to human lineage(血统), such as the brain development.

    In contrast, infants of Paranthropus robustus, that became extinct around one million years ago and were a more robust species in terms of dental anatomy, as well as infants of Australopithecus africanus, stopped drinking sizeable proportions of mother milk in the course of the first months of life.

    These differences in nursing behaviors likely come with major changes in the social structures of groups as well as the time between the birth of one child and the birth of the next.

    One of the study's lead authors, Dr Theo Tacail said: "The practice of weaning -- the duration of breastfeeding, age at non-milk food introduction and the age at cessation of suckling -- differs among the modern members of the hominid family which includes humans and modern great apes: orangutan, gorillas, chimpanzees and bonobos.

    The development of such behavioral differences likely played major roles in the evolution of the members of human lineage, being associated for instance with size and structure of social groups, brain development.

    However, getting insights into these behavioral changes from fossils that are millions of years old is a challenge and, so far, little evidence allow discussing nursing practices in these fossil species.

    The findings stress the need for further exploration of calcium stables isotopes compositions in the fossil record in order to understand the co-evolution of weaning practices with other traits such as brain size or social behaviors."

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your success. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back, you'll know you're well on your way. Good luck!

    BOXTEL, Netherlands — chickens roam the orchards, cows chew the cud and pigs roll in the mud on a warm day on a Dutch farm ——but the pastoral (乡村)scene is not as traditional as it seems.

    The farm is owned and run by a cooperative of hundreds of local consumers and aims to change habits in a low-lying country engaged in an existential fight against climate change. Nearly 200 families decide what the farm will produce — and they will eventually eat — and employ a farmer to tend to the animals for meat and eggs and grow the dozen kinds of fruits and vegetables.

    "The main aim of the members is to eat natural products, produced near to where they live, in a more sustainable (可持续的)way," said Douwe Korting, co-leader of the Boxtel Cooperative, in the southern Netherlands. People are really starting to see that a change toward a different way of eating is essential," he added.

    It costs 2,000 euros ($2,200) to join the collective (集体的)farm, which is 10 minutes by bicycle from the town, and then a weekly fee of around 10 euros per person.

    In return, members receive the food they want and stress the importance of knowing what they eat is local and seasonal.

    Known as Herenboderderij, or People's Farming, the guiding principle is that everything centers on the needs and riches of nature, even while using new technologies, " said its founder Geert van der Veer. Soon the poultry (家禽) will be joined by a robot that can sense when the fruit is ripe, as well as a drone that will survey the fields to support and reduce the needs for manpower.

    Introduction

    Blenheim Palace is one of the Europe's largest and greatest palaces. It was built between 1705 and 1722 as a reward of the British government to John Churchill, 1st Duke of Marlborough, for defeating King Louis XlV's army at Blenheim, a small Bavarian village on the Danube River. The palace was designed by Sir John Vanbrugh, which displayed strength and arm glory. It is the largest non-royal building in England and is now listed by the UNESCO as a World Heritage Site.

    Winston Churchill

    In 1874, the palace was the birthplace of the duke's most famous descendant. Winston Churchill, who was to become the UK's Prime Minister (some would say Britain's greatest 20th-century politician) and Nobel prize winner for literature. It is also in Blenheim that Winston got married to Clementine Hozier in 1908.

    A lasting exhibition is devoted to the man's life, work and writings. Winston and his wife are buried in Bladon Church within the palace.

    Opening Hours & Admission

    Blenheim is still the home of the 11th Duke of Marlborough and is therefore not open all year round (although the park is). The palace opens its doors to visitors from 12 February to 11 December. Entry to the palace, park and gardens cost £11.50 during the low season and £13 during the peak season (Easter weekend and from 28 May toll September), or £6/£8 for the park and gardens only.

    The park is open all-year round from 9am to 4:45pm (last entry). Admission is £2.50 for adults and £1.50 for children.

The following 4 famous paintings — from Jan van Eyck's portrait to Pablo Picasso's masterpiece — have stood the test of time.

The Amolfini Portrait

Jan van Eyck's Amolfini Portrait, an oil painting on wood produced in 1434, in which a man and a woman hold hands with a window behind him and a bed behind her, is undoubtedly one of the masterpieces in the National Gallery, London. This painting is as visually interesting as it is famed. It is also an informative document on fifteenth-century society, through van Eyck's heavy use of symbolism — while husbands went out to engage in business, wives concerned themselves with domestic duties.

The Starry Night

Vincent van Gogh painted The Starry Night, oil on canvas (帆布), a moderately abstract landscape painting of an expressive night sky over a small hillside village, during his 12-month stay at the mental hospital near Saint–Remy-de-Provence, France between 1889 and 1890. When the Museum of Modem Art in New York City purchased the painting from a private collector in 1941, it was not well known, but it has since become one of van Gogh's most famous works.

The Harvesters

The Harvesters is an oil painting on wood completed by Pieter Bruegel the Elder in 1565. It depicts the harvest time which most commonly occurred within the months of August and September. Nicolaes Jonghelinck, a merchant banker and art collector from Antwerp, commissioned this painting. The painting has been at the Metropolitan Museum of Art in New York City since 1919.

Guernica

Guernica, a large black-and-white oil painting, was painted by the Cubist Spanish painter, Pablo Picasso in 1937. The title 'Guernica' refers to the city that was bombed by Nazi planes during the Spanish Civil War. The painting depicts the horrors of war and as a result, has come to be an anti-war symbol and a reminder of the tragedies of war. Today, the painting is housed at the Museo Nacional Centro de Arte Reina Sofia in Madrid.
