Cloning is a process of creating a genetically identical copy of an organism. It has been widely used in animal research, but cloning primates, such as monkeys and humans, has been challenging due to technical and ethical issues. However, a recent breakthrough by Chinese scientists has opened new possibilities for primate cloning and its applications. … Read more
Introduction The collision between the Indian and Eurasian tectonic plates is one of the most spectacular geological events on Earth, giving rise to the Himalayas and the Tibetan plateau. However, the fate of the Indian plate as it slides under Eurasia is still a matter of debate among geologists. Some suggest that the plate remains … Read more
Introduction Neuroblastoma is a rare form of cancer that develops in nerve cells, mostly affecting children under the age of five. It is one of the most common solid tumors in children, accounting for about 7% of all childhood cancers. However, it is also one of the most difficult to treat, as it often does … Read more
A new study by scientists at Newcastle University sheds light on how life may have emerged from inorganic chemicals on Earth over 3.5 billion years ago. The researchers simulated the environment of ancient underwater hot springs and discovered that they could produce organic molecules, such as fatty acids, that are essential for the formation of … Read more
Introduction Human domestication of crops has shaped the evolution of plants for thousands of years, selecting for traits that improve yield, quality, and adaptation. However, domestication may also have unintended consequences on the interactions between plants and their associated microorganisms, collectively known as the plant microbiome. The plant microbiome can influence various aspects of plant … Read more
Hypersonic missiles are a new type of weapon that can fly faster and more unpredictably than conventional missiles. They are designed to evade and overcome existing missile defence systems, giving an advantage to the countries that possess them. Here is a brief explanation of how they work and why they are important. What makes a … Read more
Long COVID is a condition that affects many people who have had COVID-19, causing persistent and debilitating symptoms such as fatigue, shortness of breath, muscle aches and loss of smell. One of the most challenging aspects of long COVID is the worsening of symptoms after physical activity, known as post-exertional malaise (PEM). A new study … Read more
Light-emitting diodes (LEDs) are devices that convert electrical energy into light. LEDs have many advantages over conventional light sources, such as high efficiency, long lifetime, low power consumption, environmental friendliness, and color tunability. LEDs have been widely used in various applications, such as display panels, lighting sources, sensors, and biomedical devices. In this article, we … Read more
Boron nitride nanotubes (BNNTs) are hollow cylindrical structures that have remarkable properties such as high strength, light weight, and thermal stability. These characteristics make them attractive for various applications in aerospace, electronics, biomedicine, and energy storage. However, one of the challenges in producing BNNTs is to remove the unwanted impurities that form during the synthesis … Read more
A litre of bottled water could contain about 2.4 lakh plastic pieces on average, according to a new study published in the journal Proceedings of the National Academy of Sciences. The researchers from Columbia University analysed three popular brands of bottled water sold in the US, measuring plastic particles down to 100 nanometres in size. … Read more
