This AI powered prosthetic arm understands what you think. Muscle-controlled prosthetic limbs that patients with amputations across the globe currently use have various limitations and challenges. Good quality prosthetics parts are cumbersome, come with a complex setup, and require patients to undergo training for several months to learn their use. Interestingly, a new technology proposed by a team of researchers at the University of Minnesota (UMN) can overcome all such challenges.

It may sound like science-fiction, but the researchers claim that the new technology would allow patients to control robotic body parts using their thoughts. By employing artificial intelligence and machine learning, the researchers at UMN have developed a portable neuroprosthetic hand. The robotic hand comes equipped with a nerve implant linked to the peripheral nerve in a patient’s arm.

From TVs, to solar cells, to cutting-edge cancer treatments, quantum dots are beginning to exhibit their unique potential in many fields, but manufacturing them at scale would raise some issues concerning the environment. Scientists at Japan’s Hiroshima University have demonstrated a greener path forward in this area, by using discarded rice husks to produce the world’s first silicon quantum dot LED light.

“Since typical quantum dots often involve toxic material, such as cadmium, lead, or other heavy metals, environmental concerns have been frequently deliberated when using nanomaterials,” said Ken-ichi Saitow, lead study author and a professor of chemistry at Hiroshima University. “Our proposed process and fabrication method for quantum dots minimizes these concerns.”

The type of quantum dots pursued by Saitow and his team are silicon quantum dots, which eschew heavy metals and offer some other benefits, too. Their stability and higher operating temperatures makes them one of the leading candidates for use in quantum computing, while their non-toxic nature also makes them suitable for use in medical applications.

Investigators uncovered a diagnostic method to identify receptors on cancer cells in the blood, then engineered a cell-based therapy to target and kill tumor cells in the brain, paving the way to clinical testing.

Glioblastomas (GBMs) are highly aggressive cancerous tumors of the brain and spinal cord. Brain cancers like GBM are challenging to treat because many cancer therapeutics cannot pass through the blood-brain barrier, and more than 90% of GBM tumors return after being surgically removed, despite surgery and subsequent chemo-and radiation therapy being the most successful way to treat the disease. In a new study led by investigators at Brigham and Women’s Hospital and Harvard Medical School, scientists devised a novel therapeutic strategy for treating GBMs post-surgery by using stem cells taken from healthy donors engineered to attack GBM-specific tumor cells. This strategy demonstrated profound efficacy in preclinical models of GBM, with 100 percent of mice living over 90 days after treatment. Results will be published today (May 19, 2022) in the journal Nature Communications.

“This is the first study to our knowledge that identifies target receptors on tumor cells prior to initiating therapy, and using biodegradable, gel-encapsulated, ‘off-the-shelf’ engineered stem cell based therapy after GBM tumor surgery,” said Khalid Shah, MS, PhD, director of the Center for Stem Cell and Translational Immunotherapy (CSTI) and the vice chair of research in the Department of Neurosurgery at the Brigham and faculty at Harvard Medical School and Harvard Stem Cell Institute (HSCI).

A Massachusetts resident has tested positive for monkeypox, health officials confirmed Wednesday, making it the first case of the rare virus detected in the United States this year.

According to a release from the Massachusetts Department of Public Health, the patient is an adult male who recently traveled to Canada. The department completed initial testing Tuesday and was confirmed by the Centers for Disease Control and Prevention.

“The case poses no risk to the public, and the individual is hospitalized and in good condition,” MDPH stated in a press release. “DPH is working closely with the CDC, relevant local boards of health, and the patient’s health care providers to identify individuals who may have been in contact with the patient while he was infectious.”

During that uncomfortable period between puberty and adulthood, the brain undergoes carefully orchestrated changes in gene expression and epigenetic modification. Alcohol, unfortunately, interferes with this biological architecture. Consequently, mistakes are made, and gene expression and modification do not go as planned, leaving the person vulnerable to a lifetime of psychiatric challenges, such as anxiety and alcoholism.

A team of researchers from the University of Illinois Chicago recently found they could reverse these changes in rats via gene editing. If their findings carry through to human studies, gene editing may be a potential treatment for anxiety and alcohol-use disorder in adults who were exposed to binge drinking in their adolescence.

The relentless evolution of the coronavirus, which has spawned new variants to fuel fresh surges of disease every four to six months, could in the not-distant future propel the virus to overtake measles as the most contagious of all known infections.

Increasing infectiousness does not necessarily make the virus deadlier, but it could make it harder to control, and leave communities vulnerable to the repeated waves of illness that have defined the pandemic.

The variants now dominating around the world may be five to 10 times more infectious than the original virus that sparked the pandemic in China in late 2019, health experts believe. Lately each variant has outpaced its parent — omicron, with its massive evolutionary jump, was about three times more infectious than delta. Its subvariants — BA.2 and BA.2.12.1, which are driving the latest surge in the Bay Area — are each more infectious still, by 20% to 30%.
