Vocal biomarkers have become a buzzword during the pandemic, but what does it mean and how could it contribute to diagnostics?

What if a disease could be identified over a phone call?

Vocal biomarkers have amazing potential in reforming diagnostics. As certain diseases, like those affecting the heart, lungs, vocal folds or the brain can alter a person’s voice, artificial intelligence (A.I.)-based voice analyses provide new horizons in medicine.

Using biomarkers for diagnosis and remote monitoring can also be used for COVID-screening. So is it possible to diagnose illnesses from the sound of your voice?

Skin-like electronics could seamlessly integrate with the body for applications in health monitoring, medication therapy, implantable medical devices, and biological studies.

With the help of the Polsky Center for Entrepreneurship and Innovation, Sihong Wang, an assistant professor of molecular engineering at the University of Chicago’s Pritzker School of Molecular Engineering, has secured patents for the building blocks of these novel devices.

Drawing on innovation in the fields of semiconductor physics, solid mechanics, and energy sciences, this work includes the creation of stretchable polymer semiconductors and transistor arrays, which provide exceptional electrical performance, high semiconducting properties, and mechanical stretchability. Additionally, Wang has developed triboelectric nanogenerators as a new technology for harvesting energy from a user’s motion—and designed the associated energy storage process.

Due to their self-assembly function, DNA sensors have gained much attention as next-generation sensors that require an extremely low power supply.

Scientists have recently used iron (Fe) quantum dots (QD) electrodes to determine the spin transport properties and quantum scattering transmission characteristics of DNA sensors at room temperature. This study is available in Materials Today: Proceedings.

Explaining the potential of nanotubes further, one of the lead researchers and associate professor at Johns Hopkins University (JHU), Rebecca Schulman told IE, “Tinier plumbing might help us analyze individual molecules, which could help us make better drugs or enzymes, separate toxins, or even create better batteries by designing the conduits that ions flow through rather than using a porous material.”

She believes that although these technologies are still 10+ years away, their foundation is in things like nano-plumbing and being able to precisely measure and control the pipes the plumbing is made of.

Nanotubes are a highly evolved version of nanopores, small DNA structures proposed in some previously published studies. A nanopore is designed to serve as a conduit across a thin barrier between two chambers. Examples of such barriers are cell membranes (nanopores allow things to move in and out of a cell) and across metal or graphene sheets (like in nanopore-enabled DNA sequencing).

A new study has identified an association between receiving an influenza vaccine and a reduced risk of stroke. The research is published in the journal Neurology.

Risk factors for stroke

A stroke occurs when the blood supply to the brain is cut off, causing damage to neuronal cells that in turn affects physiological functions in the body. There are different types of strokes that can occur: ischemic – where a blockage prevents blood from reaching the brain, hemorrhagic – caused by a bleed in or around the brain and transient ischemic attacks (TIA) which are strokes that last for a short amount of time. It’s estimated that one in four people aged 25 and over will be afflicted by a stroke in their lifetime.

When Neuralink co-founder Max Hodak announced his enigmatic departure from the company earlier this year, it was unclear whether he quit due to disagreements with fellow co-founder Elon Musk or if he was fired for moving too slow on clinical trials.

Now, Futurism has learned, Hodak is working on what appears to be a well-funded new brain interface venture called Science Corp. According to an SEC filing from July, Hodak has already raised more than $47 million from 14 investors for the new company — not quite as much as Neuralink’s $363 million to date, but a rousing start that could signal growing competition in the nascent neurotech market.

Moreover, Hodak appears to be taking some talent from Neuralink with him. Alan Mardinly, Neuralink’s longtime director of biology, recently changed his LinkedIn account to say that he has been working at a “stealth startup” since July 2021 and left his position at Neuralink in August 2021 — and posted a link to Science Corp’s hiring page along with an exhortation to “join early,” strongly suggesting that he’s on board the venture.

An excellent article rebutting some of common negative reactions to the idea of de-extinction. I applaud George Church, Ben Lamm, and colleagues for their efforts to leverage the genomics revolution to recreate the wooly mammoth and the Thylacine. These represent exciting steps for repairing damaged ecosystems. Such approaches will also most likely have the side benefit of generating new technologies for biomedical applications. I’d love to see similar de-extinction efforts addressing loss of insect and microorganism biodiversity as well! #biotech #future #crispr #techforgood

When mammoths disappeared from the Arctic some 4,000 years ago, shrubs overtook what was previously grassland. Mammoth-like creatures could help restore this ecosystem by trampling shrubs, knocking over trees, and fertilising grasses with their faeces.

Theoretically, this could help reduce climate change. If the current Siberian permafrost melts, it will release potent greenhouse gases. Compared to tundra, grassland might reflect more light and keep the ground cooler, which Colossal hopes will prevent the permafrost from melting.

Suicide is the second leading cause of death for young people aged between 15 and 29 [1]. Suicidal thoughts and behaviors (STBs) typically emerge during adolescence [2]. It has been estimated that between 11 and 29% of adolescents report suicidal ideation (suicidal thoughts), and 2–10% of adolescents attempted suicide in the past year [3]. Unfortunately, the number of suicide attempts among children and adolescents has continued to increase sharply despite national and international prevention efforts [4].

To improve targeting of prevention and intervention efforts and thereby reduce the number of deaths by suicide in this age group, we must increase our understanding of the mechanisms underlying both suicidal thoughts and suicidal behaviors (including suicide attempts) in young people. Neuroimaging, including Magnetic Resonance Imaging (MRI), is a useful tool with which to identify biological risk markers for STBs in vivo and non-invasively. Many neuroimaging studies have been published examining the neural substrates of STBs in the past 20 years, but few have focused on STBs in youth (for a review, see [5]). Although several of these studies support lower regional brain volumes, particularly in ventral and dorsal prefrontal and also in temporal regions [6,7,8,9] in suicide attempters with mood disorders, negative findings have also been reported [10, 11].
