Genetic mutations increase risk of breast cancer by 80%: Experts
The subject experts suggested that to a large extent, the disease is hereditary in nature. The experts said that inheritance, either by disease history in family or by genetic changes, augments the probability of developing cancer. According to them, highly predisposed to developing breast and ovarian cancer are those whose family has a history of breast cancer or found inheriting a separate set of genes.
NASA plans to launch Mars ice mapping mission
Under the statement of intent that they have signed, NASA, the Italian Space Agency (ASI), the Canadian Space Agency (CSA), and the Japan Aerospace Exploration Agency (JAXA) announced their intention to develop a mission plan and define their potential roles and responsibilities.
SpaceX Starship SN9 prototype rocket explodes on landing after test launch| watch
The Starship SN9 that blew up on its final descent, like the SN8 before it, was a test model of the heavy-lift rocket being developed by billionaire entrepreneur Elon Musk's private space company to carry humans and 100 tons of cargo on future missions to the moon and Mars.
NASA's Perseverance rover to land on Mars next month
Launched on July 30 last year, the rover is currently closing that distance at 2.5 kilometres per second, NASA said. Once at the top of the Red Planet's atmosphere, an action-packed seven minutes of descent awaits -- complete with temperatures equivalent to the surface of the Sun, supersonic parachute inflation, and the first-ever autonomous guided landing on Mars.
Expecting mothers at high risk of death due to Covid: Study
The findings suggested that the Covid-19 mortality rate was 13 times higher in pregnant mothers than in similarly aged individuals. The team also found that pregnant women with Covid-19 had a 3.5 times higher Covid-19 associated hospitalization rate than the similarly aged general population in Washington state.
Bharat Biotech to make antigen for first-ever anti-malaria vaccine
The agreement includes the transfer of manufacturing of the RTS,S antigen part of the vaccine and the grant of a license on all rights pertaining to the RTS,S/AS01 malaria vaccine to Hyderabad-based Bharat Biotech International Ltd (BBIL). GSK will retain the production of the adjuvant of the vaccine (AS01E) and will supply it to Bharat Biotech.
Chloride-rich particles linked to visibility reduction over Delhi
The study, published in the journal Nature Geoscience, not only provides the scientific explanation for the source of high chloride in PM2.5 mass over Delhi but also quantifies its role in haze and fog formation and visibility reduction.
NASA's OSIRIS-REx spacecraft to depart asteroid Bennu on May 10
During its October 20, 2020, sample collection event, the OSIRIS-REx spacecraft, short for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer, collected a substantial amount of material from Bennu's surface, likely exceeding the mission's requirement of 60 grams.
NASA, Boeing target March 25 for next Starliner flight test
Boeing's Orbital Flight Test-2, or OFT-2OFT-2, mission will launch Starliner on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. It will dock to the space station and return to land in the western US about a week later as part of an end-to-end test flight to prove the system is ready to fly crew, NASA said in a blog post this week.
Myeloid-derived suppressor cells in blood may up severe Covid-19 risk: Research
In the study, published in the Journal of Clinical Investigation, the team researched one type of immune cell, monocytic myeloid-derived suppressor cells, or M-MDSC, and their potential role in Covid-19. The role of M-MDSC in respiratory infections, however, is largely unknown. Since low levels of T cells are a hallmark of Covid-19, it is of interest to understand the role of M-MDSCs in this disease.
