Matter is subject to gravitational attraction. Einstein’s general relativity had predicted that antimatter also should fall to Earth in the same way. However, there was no direct experimental evidence so far to show that. ALPHA experiment at CERN is...
NASA’s first asteroid sample return mission, OSIRIS-REx, launched seven years ago in 2016 to near-Earth asteroid Bennu has delivered the asteroid sample that it collected in 2020 to Earth on 24th September 2023. After releasing the asteroid sample into...
Between 1958 and 1978, USA and former USSR sent 59 and 58 moon missions respectively. The lunar race between the two ceased in 1978. End of cold war and collapse of former Soviet Union and subsequent emergence of new...
Wearable devices have become prevalent and are increasingly gaining ground. These devices usually interface biomaterials with electronics. Some wearable electro-magnetic devices act as mechanical energy harvesters to supply energy. Currently, no “direct electro-genetic interface” is available. Hence, wearable devices...
Information about “family and kinship” systems (which is routinely studied by social anthropology and ethnography) of prehistoric societies is unavailable due to obvious reasons. Tools of ancient DNA research along with archaeological contexts have successfully reconstructed family trees (pedigrees) of...
Non-native English speakers face several barriers in conducting activities in science. They are at disadvantages in reading papers in English, writing and proofreading manuscripts, and preparing and making oral presentations in conferences in English. With little support available at...
“CRISPR-Cas systems” in bacteria and viruses identify and destroy invading viral sequences. It is bacterial and archaeal immune system for protection against viral infections. In 2012, CRISPR-Cas system was recognised as a genome editing tool. Since then, wide range of...
Extinct gigantic megatooth sharks were at the top of the marine food web once. Their evolution to gigantic sizes and their extinction are not well understood. A recent study analysed isotopes from the fossil teeth and found that these...
Researchers have found that memory in aged monkey improved following a single administration of low-dose Klotho protein. It is the first time that restoring levels of klotho has been shown to improve cognition in a non-human primate. This paves the...
The first detection of carbon dioxide in the atmosphere of a planet outside the solar system, the first image of an exoplanet by JWST, the first image of an exoplanet ever taken at deep infrared wavelength, the first detection of...
Using appropriate enzymes, researchers removed ABO blood group antigens from donor kidney and lung ex-vivo, to overcome ABO blood group mismatch. This approach can solve organ shortage by improving availability of donor organs for transplantation considerably and make the...
Scientists have replicated the natural process of mammalian embryonic development in the laboratory up to the point of development of brain and heart. Using stem cells, researchers created synthetic mouse embryos outside uterus that recapitulated natural process of development...
One of the most beautiful things about mother Earth is presence of an atmosphere. Life on Earth would not have been possible without the lively sheet of air that completely embraces Earth from all around. In the early phase...
With its first view of Earth, NASA’s EMIT Mission achieves milestone towards better understanding of climate effects of mineral dust in the atmosphere.
On 27 July 2022, NASA’s Earth Surface Mineral Dust Source Investigation (EMIT), installed on the International...
Monkeypox virus (MPXV) is closely related to smallpox, the deadliest virus in history responsible for unparalleled devastation of human population in the past centuries accounting for more deaths than any other single infectious disease, even plague and cholera. With...
Fire was reported in Zaporizhzhia Nuclear Power Plant (ZNPP) in South-East of Ukraine amidst ongoing crisis in the region. The site is not affected. There is no reported change in radiation levels at the plant which is protected by...
In recently published papers, researchers have estimated the rate of supernova core collapse in the Milky Way to be 1.63 ± 0.46 events per century. Therefore, given the last supernova event, SN 1987A was observed 35 years ago in...
RNA technology has proved its worth recently in development of mRNA vaccines BNT162b2 (of Pfizer/BioNTech) and mRNA-1273 (of Moderna) against COVID-19. Based on degrading the coding RNA in animal model, French scientists have reported a potent strategy and proof of...
The search for a universal COVID-19 vaccine, effective against all present and future variants of coronaviruses is an imperative. The idea is to focus on the less-mutating, most conserved region of the virus, instead of the region that frequently mutates....
Some microbes in the deep-sea produce oxygen in a hitherto unknown way. In order to generate energy, the archaea species ‘Nitrosopumilus maritimus’ oxidises ammonia, in presence of oxygen, to nitrate. But when researchers sealed the microbes in airtight containers, without...
Scientists have developed the first patient-derived stem cell model of albinism. The model will help studying eye conditions related to oculocutaneous albinism (OCA).
Stem cells are unspecialised. They cannot do any specific function in the body but they can divide...
The researchers have studied the turbulence in Sun’s corona using radio signals sent to Earth by the ultra-low-cost Mars orbiter when the Earth and Mars were in conjunction on the opposite sides of the Sun (the conjunction usually happens...
Deltacron is not a new strain or variant but a case of co-infection with two variants of SARS-CoV-2. Over the past two years, different variants have emerged of the SARS CoV-2 strain with varying degree of infectivity and disease...
Being both carbon-free and nuclear-free is not going to be easy for Germany and European Union (EU) when trying to meet the target of reduction of greenhouse gas emissions to keep temperature rises within 1.5oC.
Over 75% of...
A clinical trial for pregnant women at high risk of a low-birth-weight baby has demonstrated that Mediterranean diet or mindfulness-based stress reduction interventions during pregnancy reduce the prevalence of low birth weight by 29-36%.
Low birth weight babies (birth weight...
