Space cups give ISS astronauts zero-gravity espresso experience
 Last year when Italy sent an espresso machine up to the International Space Station (ISS), researchers wondered how astronauts would sip their double shot espresso in a zero-gravity situation in space.
 
They came up with six funky-looking cups from a 3D printed transparent polymer that are making spending time in space a more enjoyable experience.
 
The astronauts' responses when testing out the cups range from “Hey, you can smell the coffee,” to “This is eerily like drinking on Earth”.
 
The uniquely-designed cups simply elicit happy eruptions of laughter because the astronauts readily confess they hadn't expected it to work.
 
The cup works so well that the crew is able to cruise around, do flips and even toss them back and forth -- while drinking beverages such as fruit juice, fruit smoothies and coffee.
 
“Wetting conditions and the cup's special geometry create a capillary pressure gradient that drives the liquid forward toward the face of the drinker,” explained Mark Weislogel, senior scientist and professor of mechanical engineering at Portland State University.
 
Unlike drinking a beverage from a bag, “your nose is closer to the beverage, which makes it easier to actually smell it while drinking,” he added.
 
An astronaut can drain the cup in sips or one long gulp in much the same manner as on Earth… without tipping their head, without gravity.
 
“It is a stable situation -- even though drinking scalding liquids from open containers while aboard the International Space Station is generally considered a safety concern,” Weislogel added.
 
Of the six cups currently aboard the orbiting laboratory, five hold 150 mL drink while the sixth is a 60 ml cup specifically intended for espresso.
 
The cups are complexly shaped and demonstrate that specific control of liquids can be maintained in low-gravity environments -- but with completely different fluidics principles at play than on Earth.
 
“We're enjoying watching the astronauts have fun, but also collecting plenty of data on large capillary interface configurations, stability, flow rates, transients, etc.," Weislogel noted.
 
“We have received great support for this project from US astronauts Scott Kelly and Kjell Lindgren and Japanese astronaut Kumiya Liu,” he added.
 
Last year, it was big news when Italy sent an espresso machine up to the ISS for Samantha Cristoforetti, an Italian European Space Agency astronaut.
 
This, of course, inspired a team of researchers to study the related strange fluids phenomena in low gravity -- such as espresso crema formation and settling, capillary interfaces and containment of potentially hazardous drinks within a spacecraft.
 
The next step for the team is to apply their knowledge of low-gravity capillary fluidics phenomena to design more reliable life-support systems for the space station and future spacecraft.
 
The team presented the findings at American Physical Society's 68th annual meeting in Boston, Massachusetts, this week.

No breakthrough on GST in Modi-Congress meet, more talks soon
Prime Minister Narendra Modi on Friday met his predecessor Manmohan Singh and Congress president Sonia Gandhi to discuss the contentious Goods and Services Tax (GST) bill and though no breakthrough was achieved, they agreed to meet again to break the deadlock.
 
Meanwhile, Congress termed the meeting as constructive and hoped that the government would seriously reflect on their demands on GST.
 
Speaking to reporters after the meeting, Finance Minister Arun Jaitley, who had also been present, said: "The Congress party leaders put forth their position with regard to the three issues of the bill, which they felt are of concern to them. The history and background of the legislation and the government's response to three issues in detail was explained to them."
 
"The Congress party leaders would be discussing it within their own party and there would be after sometime a fresh contact between the government and them to discuss the subject further," he added.
 
Jaitley said the government has also considered the position the opposition has taken.
 
The prime minister had invited the Congress leaders to discuss issues pending before parliament, particularly a large amount of legislative business that has accumulated over the last two sessions.
 
"Parliamentary Affairs Minister M. Venkaiah Naidu will be in touch with the leaders of Congress party in both the houses of parliament to discuss each one of the specific legislations so that work could proceed in parliament next week," Jaitley said.
 
Apart from Jaitley, Naidu was also present during the meeting.
 
The Congress said that it has been a constructive engagement and it will be a work in progress.
 
"It has been agreed that we as Congress, after this meeting, have our own discussion and deliberations and the government will also seriously reflect on demands of the Congress, which is in the interest of the economy and interest of the people of India and after that once the deliberations are complete then there would be any further contact," senior party leader Anand Sharma told reporters.
 
"We hope that the government has registered our concerns and the merits of what we are saying," he added.
 
Sharma said that the Congress was the original author of GST and its demand was neither political nor partisan.

Infant deaths: Bengal suspends, transfers Kolkata hospital staff
The West Bengal directorate of health services on Friday said four staffers of the state-run Medical College and Hospital Kolkata have been transferred and several others suspended following the death of two babies allegedly due to overheating in a warmer apparatus.
 
According to state health services director B.R. Satpathi, punitive action has been initiated against at least seven healthcare workers at the hospital, including the head of the paediatric unit and three junior doctors.
 
"The decision has been approved by Chief Minister Mamata Banerjee. Four people have been transferred to RG Kar Medical College and Hospital, including head of the paediatric unit, nursing head and the deputy. Three junior doctors and the nursing staff are on suspension. The sister-in-charge has been put on immediate suspension," Satpathi said.
 
However, a section of the nursing unit launched a protest against the suspension and transfer orders accusing the state government of not providing adequate infrastructure and staff to support the care of newborns.
 
A probe panel was set up by the authorities following allegations by their parents that the babies died in the radiant warmer apparatus due to overheating caused by negligence of the hospital staff.
 
The bereaved parents also accused the hospital of misleading on the cause of the death in the death certificate.
 
Admitted to the sick neonatal care unit, the infants died on November 21.
 
According to the WHO, newborn babies, in particular pre-term and those with low birth weight, are predisposed to hypothermia and warming devices, namely incubators and radiant warmers, are needed for them.

Don't you think these people should be charged with the case for murder?
