Children gain a valuable insight into Hong Kong’s waterworks by directing the flow of water at an attraction designed to emulate the water cycle at the Water Supplies Department’s brand new H2OPE Centre.

They learn how rain passes through catchwaters in mountains and is filtered and distributed to people’s homes at the attraction, one of the 54 games or displays at the water education centre.

Kids can also try their hand at a fishing simulator to learn about tips and advice on fishing in reservoirs and discover ways to recycle and save water at other exhibits of the 720-sq m centre, which opened in December.

“It is extremely fun. We do not have this at school. I know how to save water now,” student Kim Lam said.

“Usually, we sit in a classroom and answer questions. But now we can learn about water in Hong Kong by playing games. It is excellent,” fellow student Alan Zeng added.

Children can also watch immersive videos at the centre’s 3D dome theatre.

Deeper understanding

The department hopes the centre will raise public awareness about water conservation.

“Its exhibits, live demonstrations and interactive games help visitors gain more insight into Hong Kong’s water resources,” Water Supplies Department Senior Engineer Irene Tong explained.

People can also visit the city’s important waterworks facilities such as the Waterworks Heritage Trails and the High Island Reservoir in Sai Kung, by joining the department’s Excursion with Water Save Dave. 

Water Save Dave is the department’s mascot to help promote a water conservation culture in the community.

Water Supplies Department Engineer Fion Chan said: “Water Save Dave is blue and shaped like a water drop to encourage us to cherish every single drop of water.

“We hope that guided tours of waterworks facilities will raise the public’s awareness about water resources and conservation.”

Paris : V. Adrien Delahaye, 1879.

Evaluating dehydration severity is a challenging task. Clinical dehydration scores that combine multiple clinical findings are promising. One clinical dehydration scale score has been developed and subsequently evaluated; however, few participants in the derivation and validation studies were significantly dehydrated.

In children requiring intravenous rehydration, the dehydration scale displayed moderate reliability and weak associations with objective measures. Thus, although the scale can assist in assessing dehydration, it should not be used in isolation to dictate interventions (eg, intravenous rehydration, hospitalization). (Read the full article)

Some children with gastroenteritis fail to respond to oral rehydration. Subsequent interventions are dictated by regional preference. In North America, nasogastric rehydration is rarely administered. Caregiver and health care providers’ perspectives regarding its use have not been described previously.

Both caregivers and health care providers would select intravenous rehydration instead of nasogastric rehydration when oral rehydration fails. Greater knowledge mobilization efforts will be required for nasogastric rehydration to be adopted into clinical practice. (Read the full article)

Cerebral edema (CE) occurs frequently during treatment of diabetic ketoacidosis (DKA) in children. Severe, life-threatening CE occurs rarely, but subclinical CE is common. Whether the rate of infusion of intravenous fluids influences the occurrence or severity of CE is unknown.

This study demonstrates that the rate of fluid infusion in children with DKA does not substantially affect MRI measures of CE. Studies assessing measures other than edema formation are necessary to determine whether fluid infusion rates influence DKA-related brain injury. (Read the full article)

Forgoing artificial nutrition and hydration in children at the end of life is an acceptable practice under some circumstances. However, there is a paucity of pediatric evidence to guide health care providers’ and parents’ decision-making around this practice.

This study describes experiences of parents whose children died after forgoing artificial nutrition and hydration. All parents were satisfied with their decision and believed their child’s death was peaceful. This study adds to the limited evidence to guide clinical practice. (Read the full article)

In order to establish sustainable heat loading (heat removal and storage) in abandoned flooded mine workings it is important to understand the geomechanical impact of the cyclical heat loading caused by fluid injection and extraction. This is particularly important where significantly more thermal loading is planned than naturally occurs. A simple calculation shows that the sustainable geothermal heat flux from abandoned coal mines can provide less than a tenth of Scotland's annual domestic heating demand. Any heat removal greater than the natural heat flux will lead to heat mining unless heat storage options are also considered.

As a first step, a steady-state, fully saturated, 2D coupled hydromechanical model of a generalized section of pillar-and-stall workings has been created. Mine water rebound was modelled by increasing the hydrostatic pressure sequentially, in line with monitored mine water-level data from Midlothian, Scotland. The modelled uplift to water-level rise ratio of 1.4 mm m^–1 is of the same order of magnitude (1 mm m^–1) as that observed through interferometric synthetic aperture radar (InSAR) data in the coalfield due to mine water rebound. The modelled magnitude of shear stress at the pillar corners, as a result of horizontal and vertical displacement, is shown to increase linearly with water level. Mine heat systems are expected to cause smaller changes in pressure than those modelled but the results provide initial implications on the potential geomechanical impacts of mine water heat schemes which abstract or inject water and heat into pillar-and-stall coal mine workings.

Hydrogen sulfide (H₂S), a plant gasotransmitter, functions in the plant response to cadmium (Cd) stress, implying a role for cysteine desulfhydrase in producing H₂S in this process. Whether d-CYSTEINE DESULFHYDRASE (DCD) acts in the plant Cd response remains to be identified, and if it does, how DCD is regulated in this process is also unknown. Here, we report that DCD-mediated H₂S production enhances plant Cd tolerance in Arabidopsis (Arabidopsis thaliana). When subjected to Cd stress, a dcd mutant accumulated more Cd and reactive oxygen species and showed increased Cd sensitivity, whereas transgenic lines overexpressing DCD had decreased Cd and reactive oxygen species levels and were more tolerant to Cd stress compared with wild-type plants. Furthermore, the expression of DCD was stimulated by Cd stress, and this up-regulation was mediated by a Cd-induced transcription factor, WRKY13, which bound to the DCD promoter. Consistently, the higher Cd sensitivity of the wrky13-3 mutant was rescued by the overexpression of DCD. Together, our results demonstrate that Cd-induced WRKY13 activates DCD expression to increase the production of H₂S, leading to higher Cd tolerance in plants.

Transposable elements (TEs) can damage genomes, thus organisms use a variety of mechanisms to repress TE expression. The PIWI–piRNA pathway is a small RNA pathway that represses TE expression in the germline of animals. Here we explore the function of the pathway in the somatic stem cells of Hydra, a long-lived freshwater cnidarian. Hydra have three stem cell populations, all of which express PIWI proteins; endodermal and ectodermal epithelial stem cells (ESCs) are somatic, whereas the interstitial stem cells have germline competence. To study somatic function of the pathway, we isolated piRNAs from Hydra that lack the interstitial lineage and found that these somatic piRNAs map predominantly to TE transcripts and display the conserved sequence signatures typical of germline piRNAs. Three lines of evidence suggest that the PIWI–piRNA pathway represses TEs in Hydra ESCs. First, epithelial knockdown of the Hydra piwi gene hywi resulted in up-regulation of TE expression. Second, degradome sequencing revealed evidence of PIWI-mediated cleavage of TE RNAs in epithelial cells using the ping-pong mechanism. Finally, we demonstrated a direct association between Hywi protein and TE transcripts in epithelial cells using RNA immunoprecipitation. Altogether, our data reveal that the PIWI–piRNA pathway represses TE expression in the somatic cell lineages of Hydra, which we propose contributes to the extreme longevity of the organism. Furthermore, our results, in combination with others, suggest that somatic TE repression is an ancestral function of the PIWI–piRNA pathway.

Upper Lutetian–Bartonian sedimentary mélanges, corresponding to ancient mud-rich submarine mass transport deposits, are widely distributed over an area c. 300 km long and tens of kilometres wide along the exhumed outer part of the External Ligurian accretionary wedge in the Northern Apennines. The occurrence of methane-derived carbonate concretions (septarians) in a specific tectonostratigraphic position below these sedimentary mélanges allows us to document the relationships among a significant period of regional-scale slope failure, climate change (the Early and Mid-Eocene Optimum stages), the dissociation of gas hydrates and accretionary tectonics during the Ligurian Tectonic Phase (early–mid-Lutetian). The distribution of septarians at the core of thrust-related anticlines suggests that the dissociation of gas hydrates was triggered by accretionary tectonics rather than climate change. The different ages of slope failure emplacement and the formation of the septarians support the view that the dissociation of gas hydrates was not the most important trigger for slope failure. The latter occurred during a tectonic quiescence stage associated with a regressive depositional trend, and probably minor residual tectonic pulses, which followed the Ligurian Tectonic Phase, favouring the dynamic re-equilibrium of the External Ligurian accretionary wedge. Our findings provide useful information for a better understanding of the factors controlling giant slope failure events in modern accretionary settings, where they may cause tsunamis.

These are the Star Wars hydrating face masks from Japanese beauty product manufacturer Isshin Do. They come in Darth Vader, Stormtrooper, Darth Maul, C-3PO and Chewbacca varieties, and each contains water, glycerin, hyaluronic acid, collagen, and vitamin C to make your face feel softer than a baby Yoda's butt. For those living in Japan, you can pick up the masks for around $4 apiece from a variety of beauty retailers. For those of us not living in Japan, you can buy a 3-pack of any character for $31 from the Japan Trend Shop which, I wouldn't even kid myself, my face is not worth. I don't even buy sunscreen, I just use old spray paint I find in the garage. Also, how long you think it'll take before these are being used by couples for lewd sex acts? "Already happened." FACT. Keep going for a shot of each while I try to pretend I didn't just imagine some Chewbacca on C-3PO bedroom role playing.

Representational picture

Many people are so busy that they barely have time to eat, let alone pause for a water break, and you may find you often go hours and hours without quenching your thirst. But staying hydrated has real advantages, including helping you maintain your energy and focus so you can operate more efficiently, so it's important to give your drinking habits the attention they deserve. Dr. Manoj Kutteri, Wellness Director at Atmantan Wellness Centre gives some simple ways to make fueling up with fluid throughout the day a little easier

Always carry a water bottle
If you have a bottle within arm’s reach, it's very likely that you'll mindlessly sip from it throughout the day, without having to make a conscious effort. It is important to drink fluids during your workouts, especially if you are exercising outdoors or in a hotter climate. You should carry water with you while exercising. And it is necessary that you drink water in the few hours, leading up to your workout, as well as you need to be drinking water during the workout as well. It is recommended to drink a glass of water every 15 minutes during your exercise session

Have Infused Water
Drink infused water also called fruit-flavored water or fruit-infused water. Fruit-flavored water is a combination of fruits, vegetables, and herbs immersed in cold water. The health benefits of fruit-infused water include flushing toxins from your system, filling you up, so you don't eat much junk food, keeping your organs healthy while you are sweating, etc.

Electrolyte Drinks
Electrolytes are electrically-charged substances found in your blood, urine and other bodily fluids. They are essential to keep a healthy balance within the body and come in different forms, including chlorine, potassium, phosphate, magnesium, calcium and sodium. Sweat releases electrolytes, so in order to replenish them, you must consume foods and drinks that contain electrolytes like coconut water, citrus fruits, salt water, cranberry drink, watermelon juice, cucumber drink, etc.

Fruits and Vegetables
Another tip for staying hydrated in summer is adding fruits and vegetables with high water content to your diet. Strawberries, cucumbers and watermelon contain about 92 percent of water per volume. Other fruits with high water content are cantaloupe with 90 percent, grapefruit with 91 percent, and peaches with 88 percent. Pineapple, cranberries, orange and raspberries contain 87 percent water by weight. Also, vegetables like tomatoes, beetroot, carrots and celery contain water.
