THE HAGUE, Netherlands (AP) — All it took was a few sturdy swings with a sledgehammer and a prized painting by Vincent van Gogh was gone.
A Dutch crime-busting television show has aired security camera footage showing how an art thief smashed his way through reinforced glass doors at a museum in the early hours of March 30. He later hurried out through the museum gift shop with a Vincent van Gogh painting tucked under his right arm and the sledgehammer in his left hand.
Police hope that publicizing the images will help them track down the thief who stole Van Gogh’s “The Parsonage Garden at Nuenen in Spring 1884” from the Singer Laren Museum while it was shut down due to coronavirus containment measures.
An artificial neural network can reveal patterns in huge amounts of gene expression data, and discover groups of disease-related genes. This has been shown by a new study led by researchers at Linköping University, published in Nature Communications. The scientists hope that the method can eventually be applied within precision medicine and individualised treatment.
It’s common when using social media that the platform suggests people whom you may want to add as friends. The suggestion is based on you and the other person having common contacts, which indicates that you may know each other. In a similar manner, scientists are creating maps of biological networks based on how different proteins or genes interact with each other. The researchers behind a new study have used artificial intelligence, AI, to investigate whether it is possible to discover biological networks using deep learning, in which entities known as “artificial neural networks” are trained by experimental data. Since artificial neural networks are excellent at learning how to find patterns in enormous amounts of complex data, they are used in applications such as image recognition. However, this machine learning method has until now seldom been used in biological research.
“We have for the first time used deep learning to find disease-related genes. This is a very powerful method in the analysis of huge amounts of biological information, or ‘big data’,” says Sanjiv Dwivedi, postdoc in the Department of Physics, Chemistry and Biology (IFM) at Linköping University.

Developing an effective universal influenza vaccine against influenza virus with highly conserved antigenic epitopes could induce a broad-spectrum immune response to prevent infection.
(An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells. For example, the epitope is the specific piece of the antigen to which an antibody binds. See picture1)
Vaccination is the most effective way to prevent influenza virus infection. Current influenza vaccines are based on induction of protective antibodies against the viral surface hemagglutinin (HA) protein, which can effectively neutralize the influenza virus and significantly reduce morbidity and mortality. However, owing the variability of HA, vaccine strains need to be changed every year.
This is pretty cool:
The vaccine targets the novel coronavirus’s Achilles’ heel, its Receptor Binding Motif (RBM), a critical structure that enables the virus to bind to and infect a target cell. According to Prof. Gershoni, the vaccine would reconstruct the coronavirus’s RBM, a tiny feature of its “spike” protein. Though the virus uses many different proteins to replicate and invade cells, the “spike” protein is the major surface protein that it uses to bind to a receptor — another protein that acts like a doorway into a human cell. After the spike protein binds to the human cell receptor, the viral membrane fuses with the human cell membrane, allowing the genome of the virus to enter human cells and begin infection.
Tel Aviv University’s Professor Jonathan Gershoni has been awarded a US patent for a novel coronavirus vaccine design.
The virus is likely only to fuel the disaster preparedness industry in New Zealand and beyond. “Obviously the coronavirus is making people realize how vulnerable we all are, but what people are really concerned about is the aftermath,” said Vicino, the Vivos founder, who believes the wealthy fear an economic collapse or global depression could lead to uprisings against the top 1%. “They don’t want to have to defend their homes when the gangs of looters or marauders show up.”
Interest in New Zealand bunkers has surged.
A low-cost, easy-to-build non-invasive ventilator aimed at supporting the breathing of patients with respiratory failure performs similarly to conventional high-quality commercial devices, according to new research published in the European Respiratory Journal.
Non-invasive ventilators are used to treat patients with breathing difficulty and respiratory failure, a common symptom of more severe coronavirus disease. Non-invasive ventilation is delivered using facemasks or nasal masks, which push a set amount of pressurized air into the lungs. This supports the natural breathing process when disease has caused the lungs to fail, enabling the body to fight infection and get better.
The research paper provides a free to replicate, open-source description for how to build the ventilator. The researchers say the prototype ventilator could support treatment of coronavirus and other severe respiratory diseases in low-income regions or where ventilator supplies are limited.

ANTANANARIVO, Madagascar — The president of Madagascar Andry Rajoelina has officially launched a local herbal remedy claimed to prevent and cure the novel coronavirus. “Tests have been carried out — two people have now been cured by this treatment,” Rajoelina told ministers, diplomats and journalists at the Malagasy Institute of Applied Research (IMRA), which developed the beverage.
Announcing the brew, Andry Rajoelina drinks a bottle of ‘Covid-Organics,’ which he says has already cured 2 people; scientists warn of risks from untested herbal concoctions.
Alibaba’s founder Jack Ma said on Friday in a virtual interview with China Media Group that under the current situation of COVID-19, the internet economy is supporting the world and the internet is the technology of the future.
“No country or enterprises can be isolated from the internet,” Ma said, adding that every one of us must grasp the future and improve the country’s economic system through future technologies and ideas.

SARS-CoV-2, a coronavirus that newly emerged in China in late 2019 and spread rapidly worldwide, caused the first witnessed pandemic sparked by a coronavirus. As the pandemic progresses, information about the modes of transmission of SARS-CoV-2 among humans is critical to apply appropriate infection control measures and to slow its spread. Here we show that SARS-CoV-2 is transmitted efficiently via direct contact and via the air (via respiratory droplets and/or aerosols) between ferrets. Intranasal inoculation of donor ferrets resulted in a productive upper respiratory tract infection and long-term shedding, up to 11 to 19 days post-inoculation. SARS-CoV-2 transmitted to four out of four direct contact ferrets between 1 and 3 days after exposure and via the air to three out of four independent indirect recipient ferrets between 3 and 7 days after exposure. The pattern of virus shedding in the direct contact and indirect recipient ferrets was similar to that of the inoculated ferrets and infectious virus was isolated from all positive animals, showing that ferrets were productively infected via either route. This study provides experimental evidence of robust transmission of SARS-CoV-2 via the air, supporting the implementation of community-level social distancing measures currently applied in many countries in the world and informing decisions on infection control measures in healthcare settings.
