Poisoning attacks are among the greatest security threats for machine learning (ML) models. In this type of attack, an adversary tries to control a fraction of the data used to train neural networks and injects malicious data points to hinder a model's performance.

Researchers find new mutation in the leptin gene
The global obesity epidemic is so far-reaching it now has an overarching name: globesity. Texas Biomed Staff Scientist Raul Bastarrachea, M.D., is part of a team that discovered a new mutation in the gene that regulates the key hormone suppressing hunger called leptin. This new mutation could help researchers understand why people develop excess of body fat. Dr. Bastarrachea's research is aimed at helping tackle metabolic disorders like cardiovascular disease and diabetes which are fueled by obesity and impact millions of people around the world.

Pressure difference and vortex flow of blood in heart chambers may signal heart dysfunction
Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found—in animal studies—a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart. The new information could inform the development of new markers for cardiovascular dysfunction that can lead to heart failure.

Newly discovered immune cells at the frontline of HIV infection
Researchers at The Westmead Institute for Medical Research have discovered brand new immune cells that are at the frontline of HIV infection. Known as CD11c+ dendritic cells, these new cells are more susceptible to HIV infection and can then transmit the virus to other cells.

Spintronic memory cells for neural networks
In recent years, researchers have proposed a wide variety of hardware implementations for feed-forward artificial neural networks. These implementations include three key components: a dot-product engine that can compute convolution and fully-connected layer operations, memory elements to store intermediate inter and intra-layer results, and other components that can compute non-linear activation functions.

Artificial intelligence learns to recognize nerve cells by their appearance
Is it possible to understand the brain? Science is still far from answering this question. However, since researchers have started training artificial intelligence on neurobiological analyses, it seems at least possible to reconstruct the cellular structure of a brain. New artificial neural networks developed by the Max Planck Institute of Neurobiology and Google AI can now even recognize and classify nerve cells independently based on their appearance.

Kelly Latimer flies at the cutting edge of aviation—and soon, space
Kelly Latimer, 54, is a test pilot for Virgin Galactic and Virgin Orbit—two commercial space companies owned by British billionaire Richard Branson. For space tourism company Virgin Galactic, Latimer flies the giant, twin-fuselage aircraft known as WhiteKnightTwo, which carries a smaller spaceship at its belly to an altitude of up to 50,000 feet before the spaceship detaches and blasts off toward suborbital space. Latimer is also chief test pilot for Virgin Orbit, where she flies a modified 747 plane called Cosmic Girl. The plane carries a rocket under its left wing up to about 35,000 feet in the air, after which the rocket is released and falls for about four or five seconds before igniting and launching toward its intended orbit. Latimer is the only female test pilot out of a total of seven between the two companies.

Research team supersizes 'quantum squeezing' to measure ultrasmall motion
Physicists at the National Institute of Standards and Technology (NIST) have harnessed the phenomenon of "quantum squeezing" to amplify and measure trillionths-of-a-meter motions of a lone trapped magnesium ion (electrically charged atom).
