First Look Inside Fukushima Reactor Revealed
A robot sent to explore the submerged ruins of Japan’s Fukushima nuclear plant is offering a new look at the damage from one of history’s worst nuclear disasters. The device nicknamed “Little Sunfish” found melted clumps of material that could be the fuel debris it was sent to locate, according to updates Friday.
Worst-ever dengue outbreak kills up to 300 in Sri Lanka The worst-ever outbreak of dengue fever has killed nearly 300 people in Sri Lanka, with aid agencies warning against further spread of the mosquito-borne viral disease.
Three injured after ‘white substance’ is delivered to Borough Market restaurant Three people were injured after a mystery white substance in an envelope was delivered to a London restaurant involved in the London Bridge terror attacks.

How many nukes are in the world and what could they destroy? Tensions over nuclear weapons have been raised further after North Korea claimed to have successfully tested a hydrogen bomb.

This latest move comes amid increasing concern over North Korea’s military capabilities, with the new US administration upping its rhetoric in response. .

Fukushima Nuclear Plant Workers Unearth Suspected World War Ii Unexploded Bomb Workers at the Fukushima nuclear power plant in Japan have unearthed what appeared to be an unexploded wartime bomb.

The device was buried in the ground of a parking lot at the nuclear plant undergoing maintenance work, about half a mile away from the No.1 and No.4 reactors damaged in the devastating 2011 tsunami that caused a nuclear meltdown, hydrogen-air explosions and a leak of radioactive material at the plant.

Why a war with North Korea is unlikely The recent flurry of threats between Kim Jong-un and Donald Trump has caused much consternation. Threats can indeed be dangerous but only when they are followed up by hostile action.
Yemen cholera epidemic spreads to 21 regions The UN says the cholera epidemic in Yemen has spread to all but one of 22 regions. There are now almost 500,000 suspected cases. Aid workers say although the number is falling, they are worried it could rise again as the rainy season begins.

Technology:

Tufts of quartz clean water of toxic heavy metals When they find their way into landfill, electronic waste like phones and computers can wreak havoc on groundwater supplies, contaminating them with toxic heavy metals like lead and mercury. Scientists at Rice University have come up with new kind of filter made from carbon nanotubes and quartz fibers claimed to cleanse water of 99 percent of these types of metals. What’s more, they can be washed out and used over and over.
A Papertronic, On-Demand and Disposable Biobattery: Saliva-Activated Electricity Generation from Lyophilized Exoelectrogens Preinoculated on Paper Portable, on-demand micropower generation is provided by developing paper-based biobatteries that can deliver on-chip energy to the next generation of point-of-care (POC) diagnostic platforms. This work creates a low-cost, disposable, long shelf life and eco-friendly micropower source that can be easily integrated in paper-based POC devices and be readily activated by one drop of saliva, which is readily available in any challenging area.
US Army creates powder that recharges equipment in the field Today’s soldiers trekking around on missions need to carry pounds and pounds of electronic equipment with them, and then about that much again in batteries to power it all. The US Army has been trialing systems that harvest kinetic energy through the wearer’s walking, and now a chance discovery might also help lighten the load.
Laying Waste to Mercury: Inexpensive Sorbents Made from Sulfur and Recycled Cooking Oils Mercury pollution threatens the environment and human health across the globe. This neurotoxic substance is encountered in artisanal gold mining, coal combustion, oil and gas refining, waste incineration, chloralkali plant operation, metallurgy, and areas of agriculture in which mercury-rich fungicides are used..
Personalized cancer vaccines successful in first-stage human trials A cancer vaccine is one of the holy grails of modern medical research, but finding a way to stimulate the immune system to specifically target and kill cancer cells has proven to be a difficult task. Now two recent clinical trials that have produced encouraging results in patients with skin cancer are are providing hope for the development of personalized cancer vaccines tailored to individual patient’s tumors.
