Summary: Researchers identified two FDA-approved drugs that can mitigate or even eliminate the brain fog associated with COVID-19 infection.

Individuals with long COVID, sometimes referred to as “long-haulers,” experience symptoms that may persist for weeks, months, or even years after their acute viral infection.
Many investors are jumping to inject money into the startup.
Bill Gates and Jeff Bezos-backed foundations (Gates Frontier and Bezos Expeditions) have joined other companies in investing $75 million in Synchron, the endovascular brain-computer interface (BCI) company, according to a press release by the organization published on Thursday. This is a Series C financing round led by ARCH Venture Partners that brings the total amount raised since inception to $145 million.
Many investors on board.

Vitamin D plays an important role in the regulation of calcium and phosphorus absorption by the organism. It also helps keep the brain and immune system working. Researchers at the Federal University of São Carlos (UFSCar) in Brazil and University College London (UCL) in the United Kingdom have now shown that vitamin D supplementation reduces the risk of dynapenia in older people by 78%.
Dynapenia is an age-associated loss of muscle strength. It can be partially explained by muscle atrophy and is a major risk factor for physical incapacity later in life. People with dynapenia are more likely to fall, need to go to hospital, be prematurely institutionalized, and die.
An article on the study is published in the journal Calcified Tissue International and Musculoskeletal Research. The study was supported by FAPESP.
Computational modelling of the brain requires accurate representation of the tissues concerned. Mechanical testing has numerous challenges, in particular for low strain rates, like neurosurgery, where redistribution of fluid is biomechanically important. A finite-element (FE) model was generated in FEBio, incorporating a spring element/fluid–structure interaction representation of the pia–arachnoid complex (PAC). The model was loaded to represent gravity in prone and supine positions. Material parameter identification and sensitivity analysis were performed using statistical software, comparing the FE results to human in vivo measurements. Results for the brain Ogden parameters µ, α and k yielded values of 670 Pa, −19 and 148 kPa, supporting values reported in the literature. Values of the order of 1.2 MPa and 7.7 kPa were obtained for stiffness of the pia mater and out-of-plane tensile stiffness of the PAC, respectively. Positional brain shift was found to be non-rigid and largely driven by redistribution of fluid within the tissue. To the best of our knowledge, this is the first study using in vivo human data and gravitational loading in order to estimate the material properties of intracranial tissues. This model could now be applied to reduce the impact of positional brain shift in stereotactic neurosurgery.
Finite-element (FE)-based computational models of the human brain are an increasingly common research tool, with applications ranging from head impact to neurosurgery. Studies considering head impacts are generally concerned with traumatic brain injury (TBI), where a better understanding of the underlying mechanisms is essential for the development of prevention measures [1]. Within neurosurgery, efforts are primarily focused on tumour resection, where loss of cerebrospinal fluid (CSF) and tissue resection are responsible for much of the deformation [2]. Movement and deformation of the intact brain, known as brain shift, is clinically significant in stereotactic neurosurgical procedures such as deep brain stimulation where electrode placement accuracy correlates with patient outcomes [3].
An increase in genetic regulatory elements explains how modern humans evolved a bigger brain size than other hominins.

No surprises, but confirmation that what we think we should do actually does make a difference. Your brain is really rather amazing. Around 100 billion nerve cells collaborate to keep you nimble and quick-thinking. However, like with the rest of the body, as you age your brain may not be nearly as sharp. You may need to write things down, miss appointments, or have trouble watching TV without straining to understand the dialogue or action.

Researchers implanted 14 electrodes into the brains of volunteers with depression. One says it saved his life.
John’s life changed forever when he broke up with his girlfriend. The breakup sent him into a downward spiral, and led to his first depressive episode when he was 27 years old. “At first it’s just extreme sadness… then you start losing sleep,” says John (not his real name), who spoke on condition of anonymity. He developed crippling anxiety and experienced panic attacks and dark thoughts that eventually led him to attempt to end his own life.
Drugs didn’t work for John—he says he has tried pretty much every antidepressant, antipsychotic, and sedative out there.
One writer embarks upon the trip of a lifetime at Field Trip Health, a very particular kind of wellness clinic in Amsterdam, and recounts her experience of “macrodosing” psilocybin.
