John Giannandrea, Vice President of Engineering with responsibility for Google’s Computer Science Research and Machine Intelligence groups; leading teams in Machine Learning, Machine Intelligence, Computer Perception, Natural Language Understanding, and Quantum Computing, “I’m definitely not worried about the AI apocalypse, I just object to the hype and soundbites that some people are making” said at the TechCrunch Disrupt conference in San Francisco.

Google’s John Giannandrea sits down with Frederic Lardinois to discuss the AI hype/worry cycle and the importance, limitations, and acceleration of machine learning.

What causes aging? According to Professor David Sinclair, it is a loss of information in our epigenome, the system of proteins like histones and chemical markers like methylation that turn on and off genes. Epigenetics allow different cell types to perform their specific functions — they are what differentiate a brain cell from a skin cell. Our DNA is constantly getting broken, by cosmic rays, UV radiation, free radicals, x-rays and regular cell division etc. When our cells repair that damage, the epigenome is not perfectly reset. And hence over time, noise accumulates in our epigenome. Our cells no longer perform their functions well.

Facebook can determine where users are even if they opt out of having their whereabouts tracked, the company revealed in a letter sent to US senators.

In the missive, which was widely shared on social media Tuesday, Facebook explained ways it can still figure out where people are after they have selected not to share precise location data with the company.

The social network, which was responding to a request for information by two senators, contended that knowing a user’s whereabouts has benefits ranging from showing ads for nearby shops to fighting hackers and battling misinformation.

Columbia scientists have captured the first images of a new gene editing tool that could improve upon existing CRISPR-based tools. The team developed the tool, called INTEGRATE, after discovering a unique “jumping gene” in Vibrio cholerae bacteria that could insert large genetic payloads in the genome without introducing DNA breaks.

In the new study, published today in Nature, the researchers harnessed a Nobel Prize-winning technique called cryo-electron microscopy to freeze the gene editing complex in action, revealing high-resolution details about how it works.

“We showed in our first study how to leverage INTEGRATE for targeted DNA insertions in bacterial cells,” says Sam Sternberg, Ph.D., assistant professor of biochemistry & molecular biophysics at Columbia University Vagelos College of Physicians and Surgeons, who led the research with Israel Fernandez, Ph.D., assistant professor of biochemistry & molecular biophysics at Columbia. “These new images, a wonderful collaboration with Israel Fernández’s lab, explain the biology with incredible molecular detail and will help us improve the system by guiding protein engineering efforts.”

In laboratory experiments, a metabolic inhibitor was able to kill a variety of human cancer cells of the skin, breast, lung, cervix and soft tissues through a non-apoptotic route—catastrophic macropinocytosis.

In mouse xenograft studies, the inhibitor acted synergistically with a common chemotherapy drug, cyclophosphamide, to reduce tumor growth. Thus macropinocytosis, a rarely described form of cell death, may aid in the treatment of cancer.

“Understanding the signaling pathways underlying macropinocytosis-associated cell death is an important step in developing additional effective strategies to treat neoplasms that are resistant to apoptosis induced by chemotherapy,” said Mohammad Athar, Ph.D., professor in the University of Alabama at Birmingham Department of Dermatology.

Researchers at the University of Helsinki have discovered a novel system to generate an artificially enveloped oncolytic adenovirus to direct the immune response against cancer.

Virus-based cancer vaccines are nowadays considered an interesting approach in the field of cancer immunotherapy. Targeting tumor-associated antigens is proven to be effective. However, the identification of these antigens remains challenging.

Researchers at the Faculty of Pharmacy, Manlio Fusciello, from the research group led by Professor Vincenzo Cerullo, and Dr. Flavia Fontana, from the research group led by Professor Hélder Santos, and their co-workers, have developed ExtraCRAd, a novel cancer vaccine platform, consisting of an oncolytic adenovirus wrapped in an artificial envelope made of cancer-cell membrane. Oncolytic virus therapy uses modified viruses that can infect and destroy tumor cells but don’t harm normal cells.

Inhale flu viruses after vaccination, and the body responds with an explosion of flu-fighting antibodies, courtesy of a deep-seated memory in the immune system, a response scientists are now finding relies heavily on a complex biological conversation—” crosstalk” between the immune and central nervous systems.

A new investigation underway at the Feinstein Institutes for Medical Research in New York is revealing an interdependence between the immune and nervous system responses to any form of immunization. It has long been known that mammals store memories in the nervous and immune systems. Asking whether the two systems worked together in response to infiltrators—foreign antigens—marks a new line of scientific inquiry.

In their investigation, Feinstein researchers led by Dr. Kevin Tracey have found that antibody responses to immunization require sensory neurons. The research is posted on bioRxiv (pronounced “bio-archive”), a compilation of prepublished studies in the biological sciences.

A computational model could improve the selection of tumor antigens for personalized cancer vaccines that are now in early-stage clinical trials.

Every cell in the human body is coated with fragments of proteins called antigens that tell the immune system what’s inside the cell. Antigens presented on cells that are infected by foreign invaders or have become rogue cancers prompt an immune attack. Such antigens are often used in vaccines to spur immune responses against, for example, viruses like the flu. But to make vaccines that effectively stimulate attack against cancer, researchers need to predict exactly which tumor-specific antigens will be displayed on tumor cells and hence would be the best ones to put in a cancer vaccine.

Now, scientists at the Broad Institute of MIT and Harvard, Dana-Farber Cancer Institute, and Massachusetts General Hospital have developed a new computational tool that could help with this task. The researchers turned to machine learning to analyze a diverse set of more than 185,000 human antigens that they discovered, and generated a new set of rules that predict which antigens are presented on the surface of a person’s cells. The findings, published today in Nature Biotechnology, could aid in the development of new treatments that stimulate the immune system to attack cancer as well as viruses and bacteria.
