Could we reverse epigenetic aging by re-growing the thymus? In the future, will it be possible to extend our lives or increase our longevity? Dr. Greg Fahy is a low-temperature biologist and investigator of aging intervention in humans. His first clinical trial, intended to reverse immune system aging, provided evidence that aging could be reversed in humans.

His first clinical trial, intended to reverse immune system aging, provided the first evidence that global aging can be reversed in humans. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Test Coronavirus in minutes:

The ongoing outbreak of the novel coronavirus disease (COVID-19) has spread globally and poses a threat to public health in more than 200 countries. Reliable laboratory diagnosis of the disease has been one of the foremost priorities for promoting public health interventions. The routinely used reverse transcription polymerase chain reaction (RT-PCR) is currently the reference method for COVID-19 diagnosis. However, it also reported a number of false-positive or –negative cases, especially in the early stages of the novel virus outbreak. In this work, a dual-functional plasmonic biosensor combining the plasmonic photothermal (PPT) effect and localized surface plasmon resonance (LSPR) sensing transduction provides an alternative and promising solution for the clinical COVID-19 diagnosis. The two-dimensional gold nanoislands (AuNIs) functionalized with complementary DNA receptors can perform a sensitive detection of the selected sequences from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through nucleic acid hybridization. For better sensing performance, the thermoplasmonic heat is generated on the same AuNIs chip when illuminated at their plasmonic resonance frequency. The localized PPT heat is capable to elevate the in situ hybridization temperature and facilitate the accurate discrimination of two similar gene sequences. Our dual-functional LSPR biosensor exhibits a high sensitivity toward the selected SARS-CoV-2 sequences with a lower detection limit down to the concentration of 0.22 pM and allows precise detection of the specific target in a multigene mixture. This study gains insight into the thermoplasmonic enhancement and its applicability in the nucleic acid tests and viral disease diagnosis.

A team of transatlantic scientists, using reanalyzed data from National Aeronautics and Space Administration’s Kepler space telescope, has discovered an Earth-sized exoplanet orbiting in its star’s habitable zone, the area around a star where a rocky planet could support liquid water.

Scientists discovered this planet, called Kepler-1649c, when looking through old observations from Kepler, which the agency retired in 2018. While previous searches with a computer algorithm misidentified it, researchers reviewing Kepler data took a second look at the signature and recognized it as a planet. Out of all the exoplanets found by Kepler, this distant world – located 300 light-years from Earth – is most similar to Earth in size and estimated temperature.

No, it’s not a high budget Mission Impossible action movie, but it could have been. Tom Cruise wasn’t piloting a helicopter that grabbed a rocket falling back to the Earth. Instead, a crew wearing black Rocket Lab t-shirts with the words “recovery team” written on the back took the skies in helicopters to grab a falling rocket. Since it wasn’t Tom Cruise, the video of the team grabbing a rocket midflight ranked higher on the awesome scale.

Daring capture of Booster

A few weeks ago, Rocket Lab took a major step forward to recover boosters. In a recent release to media, Rocket Lab shared videos successfully grabbing a parachute & test booster out of the sky using a helicopter. On the first try, the helicopter grabbed the first stage test article with a grappling hook.

When researchers reported last month that the novel coronavirus causing the COVID-19 pandemic survives for days on glass and stainless steel but dies within hours after landing on copper, the only thing that surprised Bill Keevil was that the pathogen lasted so long on copper.
