Researchers almost doubled the lifespan of yeast cells by genetically rewiring the circuit that controls aging in a new proof-of-concept study.
Hollywood Park police also suggested consumers use pumps that are closer to the store or that have video surveillance as thieves typically target pumps that conceal them while they switch out their device.
Colby also told KENS 5 consumers should use the tap-to-pay option when possible.
“Really the best thing you can do is use tap-to-pay because you are not exposing your magnetic stripe. They’re going after the information on the mag stripe. It you don’t swipe the card it’s your safest bet,” Colby said.
Maybe you can’t tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an airplane part to a medical implant. Their new approach allows engineers to figure out what’s going on inside simply by observing properties of the material’s surface.
The team used a type of machine learning known as deep learning to compare a large set of simulated data about materials’ external force fields and the corresponding internal structure, and used that to generate a system that could make reliable predictions of the interior from the surface data.
The results have been published in the journal Advanced Materials, in a paper by doctoral student Zhenze Yang and professor of civil and environmental engineering Markus Buehler.
This video is about the story of two geniuses, Albert Einstein and the famous logician Kurt Godel. It is about their meeting at IAS, Princeton, New Jersey, when they both walked and discussed many things. For Godel, Einstein was his best friend and till his last days, he remain close to Einstein. Their nature was opposite to each other, yet both of them were very good friends. What did they talk about with each other? What did they share? What were their thoughts? For Godel, Einstein was more like his guide and for Einstein, it was a great pleasure to walk with him.
In the first episode, we discover their first meeting with each other and the development of friendship between them.

People’s Liberation Army (PLA) researchers claim they have created algorithm-based technology to defeat sophisticated hypersonic missile interception systems.
Engineers led by Zhang Xuesong from China’s Strategic Support Force Information Engineering University developed the algorithm that analyzes the trajectory of hypersonic missiles in order to avoid detection by missile defense systems, South China Morning Post (SCMP) reported on Saturday.
The algorithm “can analyze the trajectory of these hypersonic weapons to help them avoid missile defense systems, including advanced systems under development” in the US, claimed the engineers in a paper published in the Chinese journal Common Control and Simulation last month.
MIT engineers have designed a two-component system that can be injected into the body and help form blood clots at the sites of internal injury. These materials, which mimic the way that the body naturally forms clots, could offer a way to keep people with severe internal injuries alive until they can reach a hospital.
In a mouse model of internal injury, the researchers showed that these components—a nanoparticle and a polymer—performed significantly better than hemostatic nanoparticles that were developed earlier.
“What was especially remarkable about these results was the level of recovery from severe injury we saw in the animal studies. By introducing two complementary systems in sequence it is possible to get a much stronger clot,” says Paula Hammond, an MIT Institute Professor, the head of MIT’s Department of Chemical Engineering, a member of the Koch Institute for Integrative Cancer Research, and one of the senior authors of a paper on the study.
What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard.
The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome. While a revolution in the capacity to collect data from genomes of different species has allowed scientists to identify additions that are specific to the human genome —such as a gene that was critical for humans to develop the ability to speak—less attention has been paid to what’s missing in the human genome.
For the new study researchers used an even deeper genomic dive into primate DNA to show that the loss of about 10,000 bits of genetic information—most as small as a few base pairs of DNA—over the course of our evolutionary history differentiate humans from chimpanzees, our closest primate relative. Some of those “deleted” pieces of genetic information are closely related to genes involved in neuronal and cognitive functions, including one associated with the formation of cells in the developing brain.
Caltech researchers discovered an enzyme that enables viral vectors to cross the blood-brain barrier, potentially aiding brain disorder drug development and research.
The blood–brain barrier (BBB) is a stringent, nearly impenetrable layer of cells that guards the brain, protecting the vital organ from hazards in the bloodstream such as toxins or bacteria and allowing only a very limited set of small molecules, such as nutrients, to pass through. This layer of protection, however, makes it difficult for researchers to study the brain and to design drugs that can treat brain disorders.
Now, a new study from Caltech has identified a previously unknown mechanism by which certain viral vectors—protein shells engineered to carry various desired cargo—can cross through the BBB. This mechanistic insight may provide a new approach to designing viral vectors for research and therapeutic applications. Understanding this and other new mechanisms could also give insight into how the brain’s defenses may be exploited by emergent pathogens, enabling researchers to prepare methods to block them.
