Human heart cells behave differently in space: Study
November 11, 2019 15:47 ISTHuman heart muscle cells show changes in the way they operate in space, although they behave normally within 10 days after returning to the Earth.

NASA has detected a massive thermonuclear explosion coming from outer space, caused by a massive thermonuclear flash on the surface of a pulsar -- the crushed remains of a star that long ago exploded as a supernova.
A transit of Mercury across the Sun takes place when the planet Mercury passes directly (transits) between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. Transits of Mercury occur in May or November.
Planet Mercury will pass directly between Earth and the Sun on November 11, staging a rare celestial show. During the transit, Mercury will look like a tiny black dot gliding across the Sun's face, NASA said in a blog this week, adding that the event will be widely visible from most of Earth, including the Americas, the Atlantic and Pacific Oceans, New Zealand, Europe, Africa, and western Asia.
Unveiled on Friday, the Maxwell is NASA's first crewed X-plane in two decades. It is adapted from Italian Tecnam P2006T aircraft. NASA took delivery of its first all-electric experimental aircraft from Empirical Systems Aerospace (ESAero) of San Luis Obispo, California on October 2
The study, published in the journal Bioinspiration & Biomimetics, noted that the male mosquito flaps its long, slender wings at high frequencies while also rotating them rapidly at the end of each stroke in order to connect with the low-frequency hum of a female.
Radha Ramadevi, consultant at Sandor Life Sciences, Hyderabad, said early screening can also help in lowering expenses of poor patients who have fewer options once the disease is diagnosed at a later stage.
The sample, opened on Tuesday, was collected on the Moon by Apollo 17 astronauts Gene Cernan and Jack Schmitt, who drove a 4-cm-wide tube into the surface of the Moon to collect it and another sample scheduled to be opened in January 2020, NASA said in statement on Wednesday.
The Amazon rainforest, also known in English as Amazonia or the Amazon Jungle, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. The study by NASA has revealed shocking facts about the drying up of the Amazon rainforest.
It is also similar to the plasma density jump experienced by Voyager 1 when it crossed into interstellar space, the researchers said.
In a bid to know Supernova facts, researchers has put forth a theory that will help us understand how nuclear reactions trigger an explosion of stars and what happens during and after a supernova.
NASA is looking to send such a telescope that will be dedicated to hunting down rogue asteroids. NASA's internal committee has approved plans.
Replying to media's query if that if the ISRO would attempt another landing on Moon's south pole, Sivan replied, "Definitely". "We want to demonstrate the technology for Vikram lander landing, We are working on plan of action how to go ahead for Vikram Lander landing," the ISRO Chief informed media, who was in national capital to attend IIT-Delhi 50th convocation ceremony

As part of its early operation, it has detected 40Ar in the lunar exosphere from an altitude of about100 km, capturing the day-night variations of concentration.
The study, published in the journal Nature Communications, noted that the malaria parasite Plasmodium makes a blueprint of the proteins it needs to infect the liver while still living in the mosquito, well in advance of its life cycle stages in the human host.
"We defined the critical criteria where we can drive a flame to self-generate its own turbulence, spontaneously accelerate, and transition into detonation," said Kareem Ahmed, an assistant professor at the University of Central Florida in the US.
Looking at the prescription data from England in 2017, researchers, including those from the University of Cambridge in the UK, collated the carbon footprint data on inhalers -- commonly used for conditions such as asthma -- and compared the financial and environmental costs of different inhalers.
The researchers, including those from the University of Tennessee in the US, found that certain root-associated, or mycorrhizal, fungi that associate firmly with the cells in plant roots are one of the largest influences on plant tissue nutrient concentrations.
According to Wood, once researchers know the association between snail presence and particular habitat features, they can use drone and satellite imagery to detect those habitat features.
