Some cancers develop from defective B cells. Bruton’s tyrosine kinase inhibitors work by targeting a protein critical to the lifecycle of those B cells. Learn from Michael Wang, M.D., how these drugs work and why they’re considered a breakthrough for treating B-cell lymphomas.
“We usually conform to the views of others for two reasons. First, we succumb to group pressure and want to gain social acceptance. Second, we lack sufficient knowledge and perceive the group as a source of a better interpretation of the current situation,” explains Dr. Konrad Bocian from the Institute of Psychology at SWPS University.
So far, only a few studies have investigated whether moral judgments, or evaluations of another person’s behavior in a given situation, are subject to group pressure. This issue was examined by scientists from SWPS University in collaboration with researchers from the University of Sussex and the University of Kent. The scientists also investigated how views about the behavior of others changed under the influence of avatar pressure in a virtual environment. A paper on this topic is published in PLOS ONE.
“Today, social influence is increasingly as potent in the digital world as in the real world. Therefore, it is necessary to determine how our judgments are shaped in the digital reality, where interactions take place online and some participants are avatars, not real humans,” points out Dr. Bocian.
Bumblebees can learn how to open a two-step puzzle box by observing another trained bee, indicating that these insects can use social learning to acquire a behaviour too complex to otherwise be learnt through individual trial and error.
A team from the University of Geneva (UNIGE) has succeeded in modeling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a “sister” AI, which in turn performed them. These promising results, especially for robotics, are published in Nature Neuroscience.
Performing a new task without prior training, on the sole basis of verbal or written instructions, is a unique human ability. What’s more, once we have learned the task, we are able to describe it so that another person can reproduce it. This dual capacity distinguishes us from other species which, to learn a new task, need numerous trials accompanied by positive or negative reinforcement signals, without being able to communicate it to their congeners.
A sub-field of artificial intelligence (AI)—Natural language processing—seeks to recreate this human faculty, with machines that understand and respond to vocal or textual data. This technique is based on artificial neural networks, inspired by our biological neurons and by the way they transmit electrical signals to one another in the brain. However, the neural calculations that would make it possible to achieve the cognitive feat described above are still poorly understood.

TRANSCRIPT:
A new 3D microscope at the Yale West Campus Imaging Core will allow researchers to watch individual molecules move through living cells at 2-to 3-nanometer resolution.
The state-of-the-art tool is the first instrument of its kind installed in the Northeast.
From satellites to thermal cameras, technology has always been a powerful tool for conservation. Artificial Intelligence could be the most important yet.
“More testing, a purification system and approval from the U.S. Food and Drug Administration would be needed to put the strategy to work. But insulin produced by transgenic cows could ease shortages that often make the hormone hard to come by for the 8.4 million Americans with diabetes who rely on it to survive.”
MONDAY, March 18, 2024 (HealthDay News) — There may be an unexpected fix for ongoing shortages of insulin: A brown bovine in Brazil recently made history as the first transgenic cow able to produce human insulin in her milk.
“Our research in the past decade has made analog memristor a viable technology,” said Dr. Qiangfei Xia. “It is time to move such a great technology into the semiconductor industry to benefit the broad AI hardware community.”
Digital computing has become the norm in our everyday lives, but their limits are being reached in terms of computing power. Can analog computing step in and outperform them? This is what a recent study published in Science hopes to address as a team of researchers from the University of Southern California, TetraMem Inc., and the University of Massachusetts, Amherst (UMass Amherst) have spent the last decade developing memristors, which are capable of overcoming the computing limits of digital computing. This study holds the potential to help researchers develop more efficient methods in storing data without the drawbacks of holding too much of it, thus creating a clog.
“In this work, we propose and demonstrate a new circuit architecture and programming protocol that can efficiently represent high-precision numbers using a weighted sum of multiple, relatively low-precision analog devices, such as memristors, with a greatly reduced overhead in circuitry, energy and latency compared with existing quantization approaches,” said Dr. Qiangfei Xia, who is a professor of Electrical & Computer Engineering at UMass Amherst and a co-author on the study.
The decision follows years of controversy and the departure of one of the program’s key researchers.
