Most previous ancient DNA work involves people of European ancestry. A focus of the Emory lab, however, is exploring how environmental changes — including those caused by European contact — affected the biology of Indigenous and other populations of the Americas.

“Our work can connect people to ancestries they potentially don’t know about,” Lindo explains. “It can also give them insights into how historic, and even prehistoric, events may be affecting them today, especially in terms of health risks and disparities.”

Lindo establishes relationships with local and Indigenous people who decide whether unearthed remains from their communities will be analyzed and how the data will be used. Visiting scientists and scholars from these communities will come to the Emory lab, working alongside Emory scientists and students, exchanging knowledge, insights and perspectives.

In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals–dopamine and serotonin–are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.

Furthermore, the neurochemicals appear to integrate people’s perceptions of the world with their actions, indicating dopamine and serotonin have far more expansive roles in the human nervous system than previously known.

Known as neuromodulators, dopamine and serotonin have traditionally been linked to reward processing–how good or how bad people perceive an outcome to be after taking an action.

This latest IoT security warning is hard to believe…

Warnings that our IoT devices might be spying on us are nothing new—remember the smart speaker fiasco last year? But at least we expect those devices to be listening and can exercise some caution. The latest such warning, though, takes these risks to a new level. It turns out that there may be surprising little spies hiding in our living rooms.

Last December, the FBI warned that the perilous state of IoT security means that “hackers can use an innocent device to do a virtual drive-by of your digital life.” A week earlier, that same FBI office had cautioned on the danger that smart TVs can allow “manufacturers, streaming services, and even hackers an open door into your home.”

An experimental new vaccine claims to be able to change human DNA and could be deployed against COVID-19 by 2021 through a biochip implant.

The most significant scientific discovery since gravity has been hiding in plain sight for nearly a decade and its destructive potential to humanity is so enormous that the biggest war machine on the planet immediately deployed its vast resources to possess and control it, financing its research and development through agencies like the National Institutes of Health (NIH), the Defense Advanced Research Projects Agency (DARPA) and HHS’ BARDA.

The revolutionary breakthrough came to a Canadian scientist named Derek Rossi in 2010 purely by accident. The now-retired Harvard professor claimed in an interview with the National Post that he found a way to “reprogram” the molecules that carry the genetic instructions for cell development in the human body, not to mention all biological lifeforms.

Drone solution provider MissionGO has completed the longest organ delivery by drone in Las Vegas last week with the Nevada Donor Network. The two test flights were carrying a human organ and tissue to various locations around Las Vegas.

The first of the two flights was transporting research corneas from the Southern Hills Hospital and Medical Center to Dignity Health at the St. Rose Dominican, San Martín Campus. The flight demonstrated the viability, value, efficiency gains, and delivery speed of using drones to deliver organs and medical supplies.

The second flight delivered a research kidney from an airport to a location on the outskirts of a small town in the Las Vegas desert. This second flight was the one that marked the longest organ delivery by drone. The flight beat the previous record that was set in April 2019 also by MissionGO.

Additionally, some reports have suggested that then-President Woodrow Wilson downplayed the virus, but that is a “wrong and a false trope of popular history,” Markel said. Wilson, who would later contract the virus, was organizing and commanding the U.S. effort in World War I and once the war ended, he sailed for Paris, where he stayed until April of 1919 organizing a peace treaty and the League of Nations, Markel said.

“The federal government played a very small role in American public health during that era. It was primarily a city and state role and those agencies were hardly downplaying it,” he said.

Unlike today, there was no CDC or national public health department. The Food and Drug Administration existed but consisted of a very small group of men. Additionally, there were no antibiotics, intensive care units, ventilators, IV fluids or vaccines. “You got a bed or maybe nursing care,” Markel said.

It doesn’t appear staff or patient information was compromised.

Health care provider Universal Health Services, one of the largest chains in the US, has been hit by an apparent ransomware attack, TechCrunch reported. UHS facilities in California, Florida, North Dakota, Arizona, and other locations began noticing problems early Sunday, with some locations reporting locked computers and phone systems.

Some UHS hospitals had to use pen and paper to file patient information as a result, according to NBC News.

Air pollution involving very fine dust, such as PM2.5 particles, poses a serious threat to human health. Scientists in Austria have developed what they call the smallest particle sensor in the world, designed specifically to detect these harmful pollutants and offer a highly localized picture of air quality by being integrated into wearables and mobile devices.

According to the World Health Organization, air pollution contributes to more than four million premature deaths each year. While PM10 particles with a diameter of 10 microns or less can also make their way into their lungs, the finer PM2.5 particles are even more dangerous, as they can penetrate the lung barrier, slip into the blood stream and, through chronic exposure, cause severe forms of cardiovascular and respiratory disease, along with other health problems.

Concentrations of PM2.5 particles can be gauged through monitoring stations positioned around cities and regions, in fact the US Environmental Protection Agency uses a nationwide network of these stations to track air quality trends. But scientists from Austria’s Graz University of Technology (TU Graz) have been working on a more cost-effective, compact and versatile solution that can alert individual users of dangerous conditions in real time.

In recent years, researchers have been developing machine learning algorithms for an increasingly wide range of purposes. This includes algorithms that can be applied in healthcare settings, for instance helping clinicians to diagnose specific diseases or neuropsychiatric disorders or monitor the health of patients over time.

Researchers at Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital have recently carried out a study investigating the possibility of using deep reinforcement learning to control the levels of unconsciousness of patients who require anesthesia for a medical procedure. Their paper, set to be published in the proceedings of the 2020 International Conference on Artificial Intelligence in Medicine, was voted the best paper presented at the conference.

“Our lab has made significant progress in understanding how anesthetic medications affect neural activity and now has a multidisciplinary team studying how to accurately determine anesthetic doses from neural recordings,” Gabriel Schamberg, one of the researchers who carried out the study, told TechXplore. “In our recent study, we trained a neural network using the cross-entropy method, by repeatedly letting it run on simulated patients and encouraging actions that led to good outcomes.”
