COVID-19 vaccine study has bad news for people who skip second dose

COVID-19 vaccine study has bad news for people who skip second dose

Researchers with Northwestern University have published a new study evaluating the body's response to the COVID-19 vaccine, particularly in comparison to natural immunity and emerging variants. Among other things, the study sheds light on why choosing to skip a vaccine dose or waiting for natural immunity can backfire spectacularly.

Johnson & Johnson claims COVID-19 vaccine booster ups antibodies by 9x

Johnson & Johnson claims COVID-19 vaccine booster ups antibodies by 9x

New data was provided today by Johnson & Johnson supporting the use of a vaccine booster shot for COVID-19. This shot is designed to be a follow-up for people that've previously been vaccinated with the original single-shot Johnson & Johnson vaccine. The first shot showed neutralizing antibody responses that were "strong and stable" against COVID-19 "through eight months after immunization." This booster should extend that time and increase binding antibody responses.

New CDC study shows just how big a COVID risk the unvaccinated are taking

The US Centers for Disease Control and Prevention has updated a report on individuals ages 16 and older who have contracted COVID-19, revealing the latest figures on how many vaccinated vs unvaccinated people end up sick and hospitalized. As expected, unvaccinated individuals are far more likely to end up hospitalized with the respiratory disease.

New sensor creates electricity from urine and measures glucose levels

New sensor creates electricity from urine and measures glucose levels

Scientists from Tokyo University of science have created a new sensor designed to be fitted into diapers that generates the electricity it needs to operate directly from urine using a biofuel cell. While the device can generate the power it needs to operate using urine, it also measures glucose concentrations, helping caregivers monitor wearers for diabetes. Scientists say that glucose levels in urine are directly related to blood glucose levels.

Researchers aim to cure HIV with a ‘fundamentally different’ method

Researchers aim to cure HIV with a ‘fundamentally different’ method

Significant progress has been made in treating and, in very rare cases, curing HIV infections in humans. Though the virus can be controlled by taking a daily regimen of drugs, scientists are working toward a solution to completely eliminate the virus from the body. In a new announcement, researchers say they're going to tackle this challenge using a "fundamentally different" approach than past methods.

MIT’s inflatable robotic hand is a next-generation prosthetic

MIT has created a soft, inflatable robotic hand that it hopes will give amputees back the tactile control that's lost with a traditional prosthetic device. Engineers on the project aim to help more than 5 million people worldwide who have undergone amputation. Many prosthetic devices in use worldwide are nothing more than metal hooks or fake plastic hands that don't move.

Neurograins may revolutionize the brain-computer interface

A lot of research has been conducted into the brain-computer interface (BCI). While there are numerous reasons for the research, one of the main benefits of having a brain-computer interface is helping the paralyzed to operate next-generation prosthetic devices. Researchers from Brown University have created very small implantable computer chips called Neurograins.
