The Department of Health has wasted a total of $18.5 Billion on unused Covid supplies. This has prompted heavy criticism from the Whitehall spending watchdog. Watch further to know more.

ChatGPT, the AI chatbot developed by tech company OpenAI, can find and fix bugs in computer code as well as standard machine learning approaches – and does even better when engaged in conversation.
Dominik Sobania at Johannes Gutenberg University in Mainz, Germany, and his colleagues sought to see how well ChatGPT compared with other AI-powered coding support tools. A number of tools exist that use artificial intelligence to check programming code to ensure there are no mistakes.
A monoclonal antibody treatment was found to be safe, well tolerated, and effective in protecting against malaria in a small group of healthy volunteers who were exposed to malaria in a challenge study, according to new research published in The Lancet Infectious Diseases by researchers at the University of Maryland School of Medicine (UMSOM).
“The study demonstrates the feasibility of using monoclonal antibody therapies to help prevent malarial infection and holds promise for deployment to places where the disease is endemic,” said Kirsten Lyke, MD, Professor of Medicine and Director of the Malaria Vaccine and Challenge Unit in the Center for Vaccine Development and Global Health (CVD) at UMSOM. “This may allow us to revisit malaria eradication efforts.”
There were 241 million malaria cases and 627,000 deaths reported worldwide in 2020 alone, which is a 12 percent increase from 2019. Public health experts contend new strategies are urgently needed to achieve the United Nation’s sustainable development goal of 90 percent reduction in malaria incidence and mortality by 2030. Scientists have tried for decades to develop a highly effective malaria vaccine without much success.
Musk also teased that new products are under development, which presumably could be a new car model. Wall Street analysts expect a lower-cost EV that they have dubbed the “Model 2.”
“I should also say that we have other products in development. We’re not going to announce them obviously but they’re very exciting and I think we’ll blow people’s minds when we reveal them,” Musk said.
Other areas of growth for the company include Tesla insurance, which is currently at an annual premium run rate of $300 million. “We’re growing 20% a quarter so it’s growing faster than the growth in our vehicle business,” CFO Zachary Kirkhorn said.
Way back in 1953, Hemendra Nath Chatterjee first treated 186 patients with an “oral glucose-sodium electrolyte solution”. But it’s widely believed that “racism or the lack of a ‘scientific’ rationale prevented the widespread adoption of his work.” #IndiansInScience #LostTales
Earth’s potassium arrived by meteoritic delivery service finds new research led by Carnegie’s Nicole Nie and Da Wang. Their work, published in Science, shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our solar system and determined the composition of its planets.
“The extreme conditions found in stellar interiors enable stars to manufacture elements using nuclear fusion,” explained Nie, a former Carnegie postdoc now at Caltech. “Each stellar generation seeds the raw material from which subsequent generations are born and we can trace the history of this material across time.”
Some of the material produced in the interiors of stars can be ejected out into space, where it accumulates as a cloud of gas and dust. More than 4.5 billion years ago, one such cloud collapsed in on itself to form our sun.
In recent years, many physicists and computer scientists have been working on the development of quantum computing technologies. These technologies are based on qubits, the basic units of quantum information.
In contrast with classical bits, which have a value of 0 or 1, qubits can exist in superposition states, so they can have a value of 0 and 1 simultaneously. Qubits can be made of different physical systems, including electrons, nuclear spins (i.e., the spin state of a nucleus), photons, and superconducting circuits.
Electron spins confined in silicon quantum dots (i.e., tiny silicon-based structures) have shown particular promise as qubits, particularly due to their long coherence times, high gate fidelities and compatibility with existing semiconductor manufacturing methods. Coherently controlling multiple electron spin states, however, can be challenging.
In a new breakthrough, researchers at the University of Copenhagen, in collaboration with Ruhr University Bochum, have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Going from one to two is a minor feat in most contexts. But in the world of quantum physics, doing so is crucial. For years, researchers around the world have strived to develop stable quantum light sources and achieve the phenomenon known as quantum mechanical entanglement—a phenomenon, with nearly sci-fi-like properties, where two light sources can affect each other instantly and potentially across large geographic distances.
Entanglement is the very basis of quantum networks and central to the development of an efficient quantum computer.
An international team of scientists have demonstrated a leap in preserving the quantum coherence of quantum dot spin qubits as part of the global push for practical quantum networks and quantum computers.
These technologies will be transformative to a broad range of industries and research efforts: from the security of information transfer, through the search for materials and chemicals with novel properties, to measurements of fundamental physical phenomena requiring precise time synchronization among the sensors.
Spin-photon interfaces are elementary building blocks for quantum networks that allow converting stationary quantum information (such as the quantum state of an ion or a solid-state spin qubit) into light, namely photons, that can be distributed over large distances. A major challenge is to find an interface that is both good at storing quantum information and efficient at converting it into light.
A novel virus, potentially fatal to whales and dolphins, has been discovered by researchers at the University of Hawaiʻi Health and Stranding Lab. Prior to its discovery in 10 whale and dolphin host species across the Pacific, the virus was found in only a single marine mammal worldwide, a Longman’s beaked whale stranded on Maui in 2010. The findings are published in Frontiers in Marine Science.
The discovery of beaked whale circovirus (BWCV) in whales and dolphins expands the knowledge of marine mammal species that can become infected with the disease. Circoviruses are DNA viruses that cause disease in birds, pigs and dogs, and in severe cases can become fatal.
“Our study found Cuvier’s beaked whales tested positive for BWCV in Saipan and American Samoa, nearly 4,000 miles away from the first discovered case,” said Kristi West, director of the UH Health and Stranding Lab. “The positive cases found outside of Hawaiʻi were surprising, and indicates that this virus is spread across the Central and Western Pacific and may have a global presence in marine mammals.”
