Live human brain tissue — generously donated by brain surgery patients with epilepsy or tumors — is yielding incredible #neuroscience insights. A study on cells… See More.
As part of an international effort to map cell types in the brain, scientists identified increased diversity of neurons in regions of the human brain that expanded during our evolution.
It’s piloting the new delivery model in Logan, Queensland.
Alphabet subsidiary Wing has launched a pilot program that will have its drones fly products from the rooftops of shopping centers. In fact, it has already started the program in its biggest market, Logan, Australia. The subsidiary has teamed up with Australian retail property group, Vicinity Centres, to test the new model at Logan’s Grand Plaza, where Wing’s drones have been flying orders to customers from businesses directly below their launching pad.
Wing has been operating in Logan over the past two years, but up until now, businesses have had to co-locate their products at the company’s delivery facility. This is the first time the subsidiary is conducting deliveries from participating merchants’ existing location instead. Wing has been flying its drones from the rooftop of Grand Plaza since mid-August, delivering sushi, bubble tea, smoothies and other products from merchants in the shopping center. Starting today, the drones will also deliver over-the-counter medicine and personal care and beauty products.
Within the first six weeks of operating from the Grand Plaza, Wing’s drones have already made 2,500 deliveries to several Logan suburbs. The Alphabet company plans to expand not just its partner merchants in the center, but also its delivery coverage area. Jesse Suskin, Wing’s Head of Policy & Community Affairs in Australia, also said that if the Grand Plaza pilot is successful, the company can “potentially roll out similar models in other locations across Vicinity Centres’ retail property portfolio.”
Effort to scan the entire Human Brain continues.
Summary: A new, non-invasive neuroimaging technique allowed researchers to investigate the visual sensory thalamus, a brain area associated with visual difficulties in dyslexia and other disorders.

The visual sensory thalamus is a key region that connects the eyes with the cerebral cortex. It contains two major compartments. Symptoms of many diseases are associated with alterations in this region. So far, it has been very difficult to assess these two compartments in living humans, because they are tiny and located very deep inside the brain.
This difficulty of investigating the visual sensory thalamus in detail has hampered the understanding of the function of visual sensory processing tremendously in the past. By coincidence, Christa Müller-Axt, Ph.D. student in the lab of neuroscientist Prof. Katharina von Kriegstein at TU Dresden, discovered structures that she thought might resemble the two visual sensory thalamus compartments in neuroimaging data.
A Northwestern University research team has developed a versatile composite fabric that can deactivate both biological threats, such as the novel coronavirus that causes COVID-19, and chemical threats, such as those used in chemical warfare. A material that is effective against both classes of threats is rare.
The material also is reusable. It can be restored to its original state after the fabric has been exposed to threats by a simple bleach treatment. The promising fabric could be used in face masks and other protective clothing.
“Having a bifunctional material that has the ability to deactivate both chemical and biological toxic agents is crucial since the complexity to integrate multiple materials to do the job is high,” said Northwestern’s Omar Farha, an expert in metal-organic frameworks, or MOFs, which is the basis for the technology.
Researchers in Japan have developed a vaccination strategy in mice that promotes the production of antibodies that can neutralize not only SARS-CoV-2 but a broad range of other coronaviruses as well. If successfully translated to humans, the approach, to be published October 8 in the Journal of Experimental Medicine, could lead to the development of a next-generation vaccine capable of preventing future coronavirus pandemics.
The SARS-CoV-2 virus responsible for COVID-19 enters human cells by using its spike protein to bind to a cell surface receptor called ACE2. The receptor-binding domain of the spike protein consists of two parts: a “core” region that is very similar in all coronaviruses, and a more specialized “head” region that mediates binding to ACE2.
Antibodies that recognize the head region of the spike receptor-binding domain can block the entry of SARS-CoV-2 into cells but offer little protection against other coronaviruses, such as the SARS-CoV-1 virus responsible for the severe acute respiratory syndrome outbreak of 2002. Antibodies that recognize the core region of the spike receptor-binding domain, in contrast, can prevent the entry of various coronaviruses into human cells. Unfortunately, however, individuals exposed to the viral spike protein tend to produce lots of antibodies against the head region but few, if any, antibodies that recognize the core region.
