Although early detection of many types of cancer has contributed to the recent increases in cancer survival rates, the survival rate for has remained almost unchanged for over 20 years. Partly this is due to their late detection. Physicians often discover only after the onset of neurological symptoms, such as loss of movement or speech, by which time the tumor has reached a considerable size. Detecting the tumor when it is still small, and starting treatment as soon as possible, should help to save lives.

One possible sign that a person has a brain tumor is the presence of tumor-related extracellular vesicles (EVs) in their urine. EVs are nano-sized vesicles involved in a variety of functions, including cell-to-cell communication. Because those found in patients have specific types of RNA and membrane proteins, they could be used to detect the presence of cancer and its progression.

Experimental Cancer Therapy Shows Success in More Than 70 Percent of Patients in Global Clinical Trials

Posted by in category: biotech/medical

New York, NY (December 12, 2022) A new therapy that makes the immune system kill bone marrow cancer cells was successful in as many as 73 percent of patients in two clinical trials, according to researchers from The Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai.

The therapy, known as a bispecific antibody, binds to both T cells and multiple myeloma cells and directs the T cellsโ€”white blood cells that can be enlisted to fight off diseasesโ€”to kill multiple myeloma cells. The researchers described this strategy as โ€œbringing your army right to the enemy.โ€

The success of the off-the-shelf immunotherapy, called talquetamab, was even seen in patients whose cancer was resistant to all approved multiple myeloma therapies. It uses a different target than other approved therapies: a receptor expressed on the surface of cancer cells known as GPRC5D.

Transcendent Man: The Law of Accelerating Returns

Posted by in categories: Ray Kurzweil, robotics/AI, singularity, virtual reality

Ray Kurzweil on the Law of accelerating returns:


Ray Kurzweil: Acceleration of technology is the implication of what I call the law of accelerating returns. The nature of technological progress is exponential. If I count linearly 30 steps: 1, 2, 3, 4, 5โ€ฆ I get to 30. If I count exponentially: 2, 4, 8, 16โ€ฆ 30 steps later Iโ€™m at a billion. It makes a dramatic difference.

A New Field of Neuroscience Aims to Map Connections in the Brain

Posted by in categories: biotech/medical, neuroscience

Many of us have seen microscopic images of neurons in the brain โ€” each neuron appearing as a glowing cell in a vast sea of blackness. This image is misleading: Neurons donโ€™t exist in isolation. In the human brain, some 86 billion neurons form 100 trillion connections to each other โ€” numbers that, ironically, are far too large for the human brain to fathom.

Wei-Chung Allen Lee, Harvard Medical School associate professor of neurology at Boston Childrenโ€™s Hospital, is working in a new field of neuroscience called connectomics, which aims to comprehensively map connections between neurons in the brain.

Squid and human brains develop the same way despite diverging 500 million years ago

Posted by in categories: evolution, neuroscience

Scientists who watched nerve cells connect inside the eyes of growing squid have uncovered a remarkable secret โ€” the cephalopodsโ€™ brains independently evolved to develop in the same way ours do.

.The discovery, made using high-resolution cameras focused on the retinas of longfin squid (Doryteuthis pealeii) embryos, reveals that, in spite of 500 million years of divergent evolution, the basic blueprint for how complex brains and nervous systems evolve may be the same across a wide range of species.

The intelligence of cephalopods โ€” a class of marine animals that includes octopuses, squid and cuttlefish โ€” has long been a subject of fascination among biologists. Unlike most invertebrates, these animals possess remarkable memories; use tools to solve problems; excel at camouflage; react with curiosity, boredom or even playful malevolence to their surroundings; and can dream, if the ripples of colors that flash across their skin as they sleep are any indication.
