Sesame prawn toast is an all-time favorite part of a Chinese takeaway but have you ever tried making your own? Not only does it make for a satisfying small snack, but it's also a great way to use up the leftover bread that's been sitting in your bread bin.

Prawn toast is a Hongkongese-Cantonese dim sum dish and is an example of an early form of fusion cuisine, combining prawn paste—a staple of Hong Kong cuisine-and toast, which originates from the West. Don't forget soy sauce or sweet chilli sauce for dipping.

Method:

1. Place the prawns, garlic, ginger, egg white, sugar and soy in a food processor and make a paste. Stir in the spring onion. Remove it into a bowl. Cover and put in the refrigerator for at least 30 minutes.

2. Lightly brush one side of each slice of bread with sesame oil. Spread the prawn mixture on top. Brush the beaten egg carefully over the top and sides and sprinkle with sesame seeds so they stick to the prawn mixture.

3. Heat an inch of vegetable oil in a deep frying pan until hot, and cook each piece of bread it's easier to cook one at a time. Firstly, cook the non-spread-side down for 1 minute, then carefully turn over and cook for 1-2 mins on the prawn side or until the sesame seeds are golden and the prawn paste is cooked through.

4. Cut each piece into four triangles and enjoy!

I was excited about having a third child, but worried about the first year. A friend of mine who's a filmmaker said, "Why don't you just photograph the whole thing?" So I had one holder for the camera over the changing table and another where I nursed. I wasn't sure that anything would ever come out of it. I had not even looked at the photographs until a couple of months ago. They just seemed so quotidian that I couldn't imagine that they would be interesting at all. Time can turn photographs into metaphor or allow them to become a symbol instead of a documentary picture.

At the particular moment of having a newborn, mothers' needs are on the minds of the country. However, motherload is about what mothers don't show： the emotions and psychological states that we've all been socialized to bury. It's not so much about my personal existence as it is about the blurred（模糊的）existence, all that time spent keeping something alive.

Having a newborn is a very ugly, untidy time of life. I felt out of the picture. I felt very stressed and very needed, but also very invisible. The images get at that unreal quality of not feeling like a whole person. I'm not really in focus, because my brain isn't in focus either.

I can't tell you how many times I've checked an artist's biography to see, Oh God, she's so great, but does she have children? Like, are we in the same race? Because it's like running with weights on. But when I look at the pictures, I feel like a survivor.

Summer floods are an annual occurrence for many cities across China. According to the State Flood Control and Drought Relief Headquarters, in 2012, urban flooding affected 184 cities, while in 2013 the number was 234, and last year it was 125, it said. Now, new measures are being introduced to reduce loss of life and the economic damage caused by flooding.

One of the most effective measures to increase the efficiency of storm drains in cities would be to reduce the storm-water runoff and raise the levels of water filtration（过滤）and conservation in urban areas, experts said. To solve the problem of urban flooding once and for all, the central government has decided to push forward the "Sponge City" program, which in part borrows the experiences of low-impact development from the United States and Canada in recent years.

The program will allow at least 60 percent of rainwater to soak into the ground, rather than being discharged into rivers. The level of filtration could be further raised in some areas with low levels of rainfall to increase the use of rainwater. The project includes the development of residential communities with storage ponds, filtration pools and wetlands, plus roads and squares built with materials that will allow storm water to soak into the ground more effectively, according to the guideline.

"It would require a major shift in ideas about urban construction. Rainwater should be regarded as a resource, rather than a burden to be dealt with. Concepts of urban construction should shift from the destruction of the ecosystem to its renewal," Chen Zhenggao, Minister of Housing and Urban-rural Development, told a work conference in May. "If the urban runoff cannot be effectively filtered into the ground, the floods that follow will cause the direct loss of life and property," he said. He also believes low-impact development represents the future of the country's urbanization drive. "It（the dealing with storm water）is an issue of public security. Thus it should be a compulsory requirement when new urban areas are being planned and built," he said.

People with liver(肝)failure may in future recover by being attached to dialysis(透析)equipment to clean their blood of poisonous substances. The idea is similar to kidney dialysis, when people with kidney failure regularly go to a clinic or hospital to have their blood cleaned. Now, a new technique has shown promise in a small clinical trial, where it boosted the recovery process for people with liver failure.

Liver failure can be triggered by infections, drug overdoses, or drinking too much alcohol. One of the liver's main functions is to remove harmful elements from the blood. In severe liver failure, there is a huge build-up of poisons, which can cause damage to other organs and death.

Many poisonous substances from food and drink are transported in the blood. Initial attempts to replace the liver's function have involved simple forms of dialysis, where the blood is passed through a filter containing clean albumin(白蛋白).

This treatment is on offer in certain hospitals globally, but some trials have failed to show it provides benefit. The problem is that people with liver failure make too little albumin and what they do make doesn't function properly, says Agarwal, a doctor from the Royal Free Hospital in London. "Whatever albumin is being produced is of low quality." So Agarwal and his colleagues developed a different approach, removing the poisonous albumin from the individual's blood and replacing it with an adding of fresh albumin.

The technique was tested in 30 people in intensive care with severe liver failure caused by an outburst of alcoholic cirrhosis. Half the group had three to five dialysis sessions, while the rest received conventional care. Ten out of the 15 people who got dialysis recovered after 10 days, compared with five out of the 15 who got the conventional care. The results were presented at the International Liver Congress, which was held virtually at the end of June.

The work is at an early stage, but the results are promising. "We are really desperate to find something to bridge to transplantation." says Tobias Bottler at the University of Freiburg, Germany, who wasn't involved in the trial.
