Japan expands quasi-state of emergency

Posted by in categories: biotech/medical, government

Japan’s government is expanding a quasi-state of emergency aimed at containing the coronavirus. Infections are surging nationwide at an unprecedented pace, largely fueled by the Omicron variant.

Officials confirmed more than 60,000 new cases on Tuesday. The figure is a record high. A total of 444 people are in serious condition, up five from the day before.

More than half of Japan’s 47 prefectures reported record case counts, including Tokyo.

Team demonstrates molecular electronics sensors on a semiconductor chip

Posted by in categories: biotech/medical, computing

The first molecular electronics chip has been developed, realizing a 50-year-old goal of integrating single molecules into circuits to achieve the ultimate scaling limits of Moore’s Law. Developed by Roswell Biotechnologies and a multi-disciplinary team of leading academic scientists, the chip uses single molecules as universal sensor elements in a circuit to create a programmable biosensor with real-time, single-molecule sensitivity and unlimited scalability in sensor pixel density. This innovation, appearing this week in a peer-reviewed article in the Proceedings of the National Academy of Sciences (PNAS), will power advances in diverse fields that are fundamentally based on observing molecular interactions, including drug discovery, diagnostics, DNA sequencing, and proteomics.

“Biology works by talking to each other, but our existing measurement methods cannot detect this,” said co-author Jim Tour, Ph.D., a Rice University chemistry professor and a pioneer in the field of molecular electronics. “The demonstrated in this paper for the first time let us listen in on these molecular communications, enabling a new and powerful view of biological information.”

The molecular electronics platform consists of a programmable semiconductor chip with a scalable sensor array architecture. Each array element consists of an electrical current meter that monitors the current flowing through a precision-engineered molecular wire, assembled to span nanoelectrodes that couple it directly into the circuit. The sensor is programmed by attaching the desired probe molecule to the molecular wire, via a central, engineered conjugation site. The observed current provides a direct, electronic readout of molecular interactions of the probe. These picoamp-scale current-versus-time measurements are read out from the sensor array in digital form, at a rate of 1,000 frames per second, to capture molecular interactions data with high resolution, precision and throughput.

Elon Musk’s Brain Chip Company Is Preparing to Launch Human Trials

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience

Elon Musk’s brain chip company Neuralink appears to be gearing up to launch its first-ever human trials, with the firm now looking to recruit a director to run the tests.

According to The Guardian, the entrepreneur, who owns a variety of science-based start-ups, is preparing to take Neuralink’s brain chip research to the next stage by hiring a mission-driven Clinical Trial Director to begin human testing. The company is moving toward potentially finding a way to use the technology to treat people with brain and spinal injuries.

Brain Regeneration: Transplanting Patients’ Own Cells

Posted by in categories: biotech/medical, neuroscience

Stroke is the world’s second-leading cause of death. Survivors may suffer brain damage that causes severe impairments in motor, language or other abilities. Japanese doctors have spent years developing a treatment that regenerates the brain using the patient’s own cells. Clinical trials are underway. A participant who had complete paralysis on one side of her body can now walk. The treatment takes stem cells from the patient’s bone marrow and injects it directly into the brain.

CRISPR might be the banana’s only hope against a deadly fungus

Posted by in categories: biotech/medical, genetics, government

Circa 2019


The race to engineer the next-generation banana is on. The Colombian government confirmed last month that a banana-killing fungus has invaded the Americas — the source of much of the world’s banana supply. The invasion has given new urgency to efforts to create fruit that can withstand the scourge.

Scientists are using a mix of approaches to save the banana. A team in Australia has inserted a gene from wild bananas into the top commercial variety — known as the Cavendish — and are currently testing these modified bananas in field trials. Researchers are also turning to the powerful, precise gene-editing tool CRISPR to boost the Cavendish’s resilience against the fungus, known as Fusarium wilt tropical race 4 (TR4).
