Until just a few years ago, stellar black holes could only be discovered when they gobbled up gas from a companion star, the researchers said. This process creates powerful X-ray emissions, detectable from the Earth, that reveal the presence of the collapsed object, they said.
The researchers mapped the genes that are essential to this process and added some of them to the bacteria genome in their lab.
The study, led by Roxy Mathew Koll of the Pune-based Indian Institute of Tropical Meteorology (IITM) warned that warming of the ocean has altered the most dominant mode of weather fluctuation originating in the tropics, known as the Madden Julian Oscillation (MJO), which has reduced rainfall in northern India between the months of November and April.
The Indian space agency has a busy launch schedule this fiscal with about 13 missions on its menu, said a top official. The Indian Space Research Organisation (ISRO) has planned 13 missions during this fiscal -- six launch vehicle missions and seven satellite missions before March 2020, said its Chairman K. Sivan post the successful launch of Cartosat-3 and 13 nano satellites from the US.
Researchers from the University of California (UC), Riverside in the US noted that microgravity environment encountered in space has profound effects on human physiology, leading to clinical symptoms and illnesses including gastroenteritis.
Alcohol molecules, abundant in the atmosphere, can reduce the formation of hazardous polluting particles that make up haze, according to a study which may lead to more accurate models for air pollution, weather, and climate. The researchers also decoded how air pollutants form and grow in haze.
The findings were based on 111,370 participants of the UK Biobank study cohort, who underwent eye tests from 2006 to 2010 at sites across Britain. The participants underwent a test to measure intraocular pressure, and a laser scan of the retina to measure thickness of their eye's macula, the central area of the retina.
In the study published in the journal Nature Communications, the researchers described a process that may unlock the commercial potential of this low-calorie, low-glycemic sugar.
The underwater rover is NASA's hope for exploring distant ocean worlds, such as Jupiter's moon Europa and Saturn's moon Enceladus.
Researchers have discovered a new brain-circuit system in mice that sheds light on how the rodents transition from moderate to compulsive alcohol consumption -- an advance that may lead to the development of new approaches to study drug addiction in humans.
The study, published in the journal Geophysical Research Letters, compared chemical deposits found on present-day corals -- that are dependent on water temperature -- with similar deposits on older coral records representing relevant sea surface temperatures from the past 7,000 years.
Emergency responders could cut costs and save time by using near-real-time satellite data along with other decision-making tools after a flooding disaster, according to a study by NASA. The study, published in the journal Frontiers in Environmental Science, estimated the value of using satellite data in disaster scenarios.
The infernal landscape of Dallol, located in the Ethiopian depression of Danakil, extends over a volcanic crater full of salt, where toxic gases emanate and water boils in the midst of intense hydrothermal activity.
India's Polar Satellite Launch Vehicle (PSLV) rocket is expected to put 14 satellites into orbit in about 27 minutes after its lift off at 9.28 a.m. on November 27 from the second launch pad at the Sriharikota rocket port in Andhra Pradesh. The Indian Space Research Organisation (ISRO) will be sending up its PSLV-XL variant with 14 satellites.
The researchers, including those from George Washington University in the US, detected a burst on January 14 labeled GRB 190114C which led to a collaborative effort to observe the radiation coming from the source using more than 20 observatories and instruments around the world.
The study, published in the journal Biology Letters, provides the first quantitative evidence for legislative bodies to regulate noise pollution more effectively. The World Health Organization (WHO) has said the noise is one of the most hazardous forms of pollution, the researchers noted
The study, published in the journal Nature Astronomy, measured the vapour by peering at Europa through W. M. Keck Observatory in Hawaii, US.
The researchers said they did not consider pigeon social patterns for their estimation since earlier research had shown that hierarchies between the birds were independent of the dominance they exhibited during flight. Chen and his team suggested that their method could be used to study other coordinated behaviours, and plan to examine the collective functioning of cells in the immune system.
The team discovered the sugars by analyzing powdered samples of the meteorites using gas chromatography mass spectrometry, which sorts and identifies molecules by their mass and electric charge.
Published in the journal JNCI Cancer Spectrum, the study based on a National Health Insurance dataset in Taiwan between 2000 and 2013 followed 22,853 thyroid cancer, 13,040 leukemia and 20,157 non-Hodgkin lymphoma cases.
