The WHO said there are currently nine deaths and 16 suspected cases with symptoms including fever, fatigue, diarrhea and vomiting. The agency said it was sending medical experts to help officials in Equatorial Guinea stop the outbreak and was also sending protective equipment for hundreds of workers.
What is the Marburg virus?
Like Ebola, the Marburg virus originates in bats and spreads between people via close contact with the bodily fluids of infected people, or surfaces, like contaminated bedsheets.
BERLIN, Feb 19 (Reuters) — Clinical trials for BioNTech’s (22UAy. DE) cancer vaccines should start this year in Britain, marking an important step towards their possible sale on the open market, the German company’s top executive Ugur Sahin told magazine Der Spiegel.
BioNTech, known for its COVID vaccine with U.S. partner Pfizer (PFE.N), is currently deciding which types of cancer it wants to test its personalized cancer immunotherapies on and the locations where it will conduct the trials, Sahin said.
The company wants these therapies, which are based on messenger RNA (mRNA) technology similar to the one that underpins its COVID-19 vaccine, to soon become a regular treatment for cancer patients.
Documents related to Tesla’s Hardware 4 radar have now been made public by the Federal Communications Commission (FCC). Numerous photos of the new radar unit’s exterior and interior have also been released. Tesla describes its new radar as “a non-pulsed Automotive Radar which operates in the 76–77 GHz spectrum and supports 3 sensing modes.”
Tesla also noted that the new radar unit measures approximately 196 mm (Length) x 82 cm (Width) x 40 mm (Height).
Following are some exterior photos of Tesla’s new radar unit.
Throughout billions of years, galaxies expand and evolve through the appropriately titled “galactic immigration” events, which involve the formation of new stars and mergers with other galaxies. Scientists examine the movements of individual stars within a galaxy and its wide halo of stars and dark matter to learn more about the histories of these immigration episodes. But until now, such cosmic archaeology has only been possible in our galaxy, the Milky Way.
An international team of researchers has uncovered striking new evidence of a large galactic immigration event in the Andromeda Galaxy. Star motions exhibit complex patterns indicating migratory history similar to the Milky Way. The new findings were attained using Nicholas U.’s Dark Energy Spectroscopic Instrument, which the DOE operates.
A team of astronomers studied the motions of nearly 7,500 stars in the inner halo of the Andromeda Galaxy, also known as Messier 31 (M31). They found patterns in their positions and motions that indicated how these stars originated as a part of an earlier galaxy that joined M31 about 2 billion years ago. Although such patterns have long been anticipated by theory, they have never been observed in a galaxy with such clarity.
A video series looking at concepts for truly huge structures that we might see in the future. We begin with ground-based and Low Orbit structures to help us get up into space and proceed up through artificial habitats and planets to structures which encompass stars and can even move them.

Scientists’ insatiable search for finding another planet that could support human life has just got a leg up following the discovery of two Earth-like alien worlds. Both the spatial bodies have a mass similar to that of Earth and have been found in the habitable zone of a star so far known as GJ 1002. The star is one of the dwarf stars referred to as M dwarfs, which are stars that have only a fraction of the Sun’s mass and luminosity.
The discovery was made by scientists working at the Instituto de Astrofísica de Canarias (IAC) in Spain. Astrophysicist Vera María Passenger explained to Science Alert that GJ 1,002 was a “dwarf” star with a mass only one-eighth that of the Sun. “It is quite a cool, faint star. This means that its habitability zone is very close to the star.”
The World Wide Web was originally conceived and developed at CERN to meet the demand for automated information-sharing between scientists in universities and institutes around the world. From software development, to data processing and storage, networks, support for the LHC and non-LHC experimental programme, automation and controls, as well as services for the accelerator complex and for the whole laboratory and its users, is at the heart of CERN’s infrastructure.
The Worldwide LHC Grid (WLCG) – a distributed infrastructure arranged in tiers – gives a community of thousands of physicists near real-time access to LHC data. The CERN data centre is at the heart of WLCG, the first point of contact between experimental data from the LHC and the grid. Through CERN openlab, a unique public-private partnership, CERN collaborates with leading ICT companies and other research organisations to accelerate the development of cutting-edge ICT solutions for the research community. CERN has also established a medium-and long-term roadmap and research programme in collaboration with the high energy physics and quantum-technology research communities via the CERN Quantum Technology Initiative (QTI).
This video will aim to provide detailed information regarding the use of robots in healthcare, specifically the surgical robots. The video consists of 4 subtopics: history of surgical procedure, introduction to surgical robots, the da Vinci surgical system with Dr. Yasufuku’s interview and robotics in remote healthcare and future advancement. The full-length of the interview will be posted on the Demystifying Medicine Soundcloud account and as a YouTube Podcast. For more information regarding the Da Vinci Surgical System, please visit https://www.davincisurgery.com/about-us/privacy-policy. (The animation of Da Vinci Surgical System during the News section was used with permission from Intuitive.)
Finally, we would like to thank Dr. Kazuhiro Yasufuku for his time and contribution to our video through his excellent interview. For those who are interested to learn more about his research, please visit https://www.yasufukuresearch.com/.
The video was made by McMaster students Allan Li, Gurkaran Chhaggar, Mateo Newbery Orrantia, and Nadia Mohammed in collaboration with Dr. Yasufuku and the McMaster Demystifying Medicine Program.

Atoms are made of protons, neutrons and electrons. And they are small. So small that 100 million hydrogen atoms would span the width of your fingernail. String theory proposes that at the most fundamental level of space there are objects that are much smaller than these elementary particles: tiny little filaments of energy, called “strings.”
A new method learns prompts from an image, which then can be used to reproduce similar concepts in Stable Diffusion.
Whether DALL-E 2, Midjourney or Stable Diffusion: All current generative image models are controlled by text input, so-called prompts. Since the outcome of generative AI models depends heavily on the formulation of these prompts, “prompt engineering” has become a discipline in its own right in the AI community. The goal of prompt engineering is to find prompts that produce repeatable results, that can be mixed with other prompts, and that ideally work for other models as well.
In addition to such text prompts, the AI models can also be controlled by so-called “soft prompts”. These are text embeddings automatically derived from the network, i.e. numerical values that do not directly correspond to human terms. Because soft prompts are derived directly from the network, they produce very precise results for certain synthesis tasks, but cannot be applied to other models.
