The spillover of bird flu to mammals must be ‘monitored closely,’ WHO officials warn: ‘We need to be ready to face outbreaks in humans’

Posted by in categories: biotech/medical, health

H5N1 avian flu has existed for a quarter century. Only rarely have human cases occurred, with no sustained transmission reported. But “we cannot assume that will remain the case,” WHO Director General Tedros Adhanom Ghebreyesus said at a news conference. New, frequent reports that the disease has crossed into small mammals like minks, otters, foxes, and sea lions are cause for alarm, given the species’ similarities with humans, he noted.

While the risk to people remains low, public health officials must prepare “to face outbreaks in humans, and be ready also to control them as soon as possible,” Dr. Sylvie Briand, director of Global Infectious Hazard Preparedness and Emergency Preparedness at the WHO, told Fortune.

Ghebreyesus cautioned against touching or collecting sick or dead animals, and encouraged those who encounter such to report them to local authorities. Countries must strengthen their avian flu surveillance in areas where humans and wild animals interact, he insisted. And public health officials must work with manufacturers to ensure that vaccines and antivirals are available for global use, he said.

Recovering “Hidden Knowledge” — How an Asthma Medication Could Restore Memories

Posted by in categories: biotech/medical, genetics

Students often sacrifice sleep to study for exams, but lack of sleep can negatively impact memory. Now, University of Groningen neuroscientist Robbert Havekes has found that sleep deprivation hinders recall, not retention of information. Havekes and his team used optogenetics and the drug roflumilast to make “hidden knowledge” obtained while sleep-deprived accessible again days later. Their findings were recently published in the journal Current Biology.

Havekes, associate professor of Neuroscience of Memory and Sleep at the University of Groningen, the Netherlands, and his team have extensively studied how sleep deprivation affects memory processes. “We previously focused on finding ways to support memory processes during a sleep deprivation episode”, says Havekes.

However, in his latest study, his team examined whether amnesia as a result of sleep deprivation was a direct result of information loss, or merely caused by difficulties retrieving information.

This tech can print 3D objects with sound in ‘one-shot’ process

Posted by in categories: biotech/medical, engineering, holograms

The “one-shot” process paves the path for cutting-edge 3D cell culture methods with biomedical engineering applications, claim the scientists.

German scientists have created a new technology that helps them print 3D objects with sound waves.

The design creates pressure fields using several acoustic holograms, which can be used to print solid particles, gel beads, and even living cells, according to the study released on Thursday.

Doctor ChatGPT? AI-bot almost passes the US Medical Licensing Exam

Posted by in categories: biotech/medical, health, robotics/AI

What’s next?

Increasingly it seems there is nothing that ChatGPT cannot do, even consulting judges in cases and boosting research. Now, the AI chatbot has been found to score at or around the approximately 60 percent passing threshold for the United States Medical Licensing Exam (USMLE), “with responses that make coherent, internal sense and contain frequent insights.”

This is according to a study published on Thursday in the open-access journal PLOS Digital Health.

Man’s prostate cancer leads him to speak in an Irish accent

Posted by in category: biotech/medical

The doctors explain it as a rare case of foreign accent syndrome.

A man suffering from prostate cancer started sporting an Irish accent in what is one of the few documented reports of the condition and the first ever associated with this type of cancer. Sadly, the man ultimately passed away from his disease.

A rare condition.

Autofluorescence-free, imaging-guided precision therapy for rheumatoid arthritis

Posted by in categories: biotech/medical, life extension, nanotechnology

Rheumatoid arthritis (RA), known as “immortal cancer,” is a chronic, progressive autoimmune inflammatory disease. The development and application of an RA high-sensitivity theranostics probe can help to accurately monitor the progression and realize the efficient treatment of RA.

In a study published in Advanced Science, a research group led by Prof. Zhang Yun from Fujian Institute of Research on the Structure of Matter of the Chinese Academy of Sciences developed a dual-triggered theranostics based on persistent luminescence nanoparticles (PLNPs) for RA autofluorescence-free imaging-guided precise treatment and therapeutic evaluation.

The researchers first prepared a renewable near-infrared (NIR)-emitting Zn1.3 Ga1.4 Sn0.3 O4:0.5%Cr3+, 0.3%Y3+ (ZGSO) PLNPs by a facile mesoporous silica template method.
