Lack of cleaning in brain cells causes Alzheimer's: Study

Lack of cleaning in brain cells causes Alzheimer’s: Study

February 18, 2019 12:47 pm

London: A weakened cleaning system of the brain cells in animals and humans is central to developing Alzheimer’s disease, according to a study which may lead to new treatments for the neurodegenerative disorder. Researchers, including those from the University of Copenhagen in Denmark, found that improving mitophagy — the cleaning system of the brain cells […]

Massive mountains discovered under Earth’s crust

February 17, 2019 2:06 pm

Washington:    Scientists have discovered massive mountains in the Earth’s mantle, an advance that may change our understanding of how the planet was formed. Most school children learn that the Earth has three layers: a crust, mantle and core, which is subdivided into an inner and outer core. While that is not wrong, it does […]

Scientists upcycle plastic bags to create battery parts

February 14, 2019 2:57 pm

Washington: Scientists have created a way to convert plastic bags into carbon chips that could be used in batteries powering our smartphones and other devices. Plastic bag pollution has become a huge environmental problem, prompting some cities and countries to heavily tax or ban the sacks. Many plastic bags are used only once and then disposed, ending up in landfills, oceans and elsewhere in […]

Mars may have underground volcanic activity

Mars may have underground volcanic activity

February 13, 2019 5:26 pm

Washington: Mars may have volcanic activity below its surface, according to scientists who argue that without an underground source of heat it would not be possible for the Red Planet to host liquid water. Previous research has suggested that liquid water is present beneath the south polar ice cap of Mars. According to the study published in the AGU […]

Novel test can non-invasively identify fatal heart disease

Novel test can non-invasively identify fatal heart disease

February 10, 2019 3:56 pm

Washington: Cardiac magnetic resonance (CMR) can non-invasively identify the severity of heart disease and also predict which cases are potentially fatal, scientists say. According to the researchers from Duke University in the US, the method has potential as a non-invasive, non-toxic alternative to stress echocardiograms, catheterisations and stress nuclear exams in diagnosing disease. “We’ve known for some time that CMR is effective at diagnosing coronary […]

Fasting may help boost metabolism: Study

Fasting may help boost metabolism: Study

February 9, 2019 3:29 pm

Tokyo: Occasional fasting may not only help people lose weight but also boost their metabolic activity, generate antioxidants, and reverse some effects of ageing, a study claims. Scientists at the Okinawa Institute of Science and Technology (OIST) and Kyoto University in Japan identified 30 previously-unreported substances whose quantity increases during fasting and indicate a variety of health benefits. “We have been researching ageing and metabolism […]

High-risk HPV may up heart disease risk: Study

February 7, 2019 7:01 pm

Seoul: Infection with high-risk strains of the human papillomavirus (HPV), which have been linked to cancer, might increase the risk of cardiovascular disease, a study warns. While cardiovascular disease has known risk factors — such as cigarette smoking; high cholesterol, high blood pressure, physical inactivity, poor diet, obesity and diabetes — to prevent cardiovascular disease, it is important to uncover other potential contributors. One potential […]

NASA’s first mini-spacecraft in deep space go silent

February 7, 2019 3:36 pm

Washington: NASA has lost touch with the first mini-spacecraft that ventured into deep space, according to the US space agency which said that it is unlikely the twin CubeSats will be heard from again. The MarCO CubeSats were launched last year to test if such low-cost technology can operate in deep space. The twins, nicknamed EVE and WALL-E after characters from a Pixar […]

Bengaluru: The Indian Space Research Organisation is all set to launch its 40th communication satellite GSAT-31 on Wednesday from the spaceport in French Guiana. The satellite with a mission life of 15 years will provide continuity to operational services on some of the in-orbit satellites and augment the Ku-band transponder capacity in Geostationary Orbit, the space agency said. In a statement, the Indian Space Research […]

New clues to controlling HIV found

New clues to controlling HIV found

February 4, 2019 1:41 pm

Toronto: Researchers are harnessing the immune system to reveal new clues that may help produce a vaccine against the human immunodeficiency virus (HIV). The researchers from the Simon Fraser University (SFU) in Canada and the University of KwaZulu-Natal in South Africa identified a connection between infection control and how well antiviral T cells respond to diverse HIV sequences. HIV adapts to the human immune system by altering its […]
