Employees at Jeff Bezos’ aerospace firm Blue Origin are outraged that senior leadership is pressuring workers to conduct a test launch of the company’s New Shepard rocket — designed to take wealthy tourists into space — while the COVID-19 pandemic devastates the United States.

To conduct the flight, Blue Origin officials are considering transporting employees from the company’s main headquarters in Kent, Washington — a town near Seattle where COVID-19 cases have surged — to a small town in West Texas called Van Horn. The town, which has a population of just over 2,000, is home to Blue Origin’s test launch facility where the company has conducted all past flights of the New Shepard rocket.

Many employees fear that traveling to Van Horn might expose them to the novel coronavirus and inadvertently introduce COVID-19 to the residents of the rural town where there is very little infrastructure to handle an outbreak. The Verge spoke exclusively with four Blue Origin employees who all asked to remain anonymous for fear of retaliation from the company. They say they are frustrated by the company’s desire to conduct a launch, as it could unnecessarily jeopardize the health of employees at Blue Origin and residents of Van Horn.

Broadly speaking, animals tend to be sexually dimorphic. You have males, with small gametes, and females, with large gametes, both of which are required for sexual reproduction. Every now and again, though, nature throws a curveball — producing an organism that’s a combination of both sexes, divided straight down the middle.

This condition is known as gynandromorphism, and scientists have just found the first known gynandromorphic individual of its species in a nocturnal bee native to Central and South America, Megalopta amoenae.

On its left side, the bee is physiologically male. It has a small, dainty mandible, a long antenna, and a thin, delicate hind leg with fewer bristles. The right side has female characteristics — a shorter antenna, a pronounced, toothed mandible, and a thick, hairy hind leg.

Giant elliptical galaxies are not likely to be havens for technological life, argues new paper.

I recognized that the model used in the 2015 paper —- along with the known distributions and numbers of spiral and elliptical galaxies —- violated the Principle of Mediocrity, says Whitmire. That means if a technological species was selected at random anywhere in the local universe, the probability that it would reside in an elliptical galaxy would be 99 percent. Since we earthlings don’t find ourselves in an elliptical galaxy, Whitmire says this creates what he calls a statistical paradox.

My solution was to look for physical processes that would mitigate this inconsistency, says Whitmire. Current observations show that the ancestors of today’s large elliptical galaxies were once more compact, he says. This was the key, says Whitmire. This means that when these galaxies went through their early high-energy quasar and starburst phases, the radiation doses to young planets within these galaxies would have been lethal and permanent, he says.

But giant elliptical galaxies are prone to higher metallicities which means that they are also likely to form more gaseous planets, says Whitmire. Gaseous planets are not conducive to forming habitable planets around solar type stars, he says. That’s because they tend to migrate inward and gravitationally destabilize terrestrial type planets orbiting closer to their parent stars.

Ivermectin is an inhibitor of the COVID-19 causative virus (SARS-CoV-2) in vitro.

• A single treatment able to effect ∼5000-fold reduction in virus at 48h in cell culture.

• Ivermectin is FDA-approved for parasitic infections, and therefore has a potential for repurposing.

• Ivermectin is widely available, due to its inclusion on the WHO model list of essential medicines.

Studies of hibernating animals suggest that the molecular and synaptic integrity of neurons in the cerebral cortex that underlie self and consciousness is maintained in many cases when from the outside the brain appears dead.

A striking feature of medicine over the past few centuries has been our growing ability to bring people back from the “dead.” For most of human history, patients who were unconscious and not breathing were treated as though they had died. But the concept of resuscitation emerged as doctors grew to understand the basic function of the lungs and airways. That led to new techniques and tools capable of restoring both breathing and heartbeat — and the realization that cardiac arrest was not always a death sentence. That, in turn, gave rise to a distinction between what’s now called clinical death versus brain death.

Today that brain focus continues, but with a growing glimmer of hope that even brain death might be reversible in some instances. These dreams are fueled by research showing that the disappearance of brain function is not the same as deletion of computer files. Rather, it represents a deterioration of the pathways that normally enable different parts of the brain to communicate. This idea was bolstered recently with the 2017 success in France, where a patient was partially revived from a 15-year vegetative state. It also dovetails with insights from the study of hibernating animals.

An AI that translates brainwaves into sentences.

Scientists have developed a new artificial intelligence-based system that converts brain activity into text which could result in transforming communication for people who can’t speak or type.

The electrodes on the brain have been used to translate brainwaves into words spoken by a computer which is helpful for people who have lost the ability to speak. When you speak, your brain sends signals from the motor cortex to the muscles in your jaw, lips, and larynx to coordinate their movement and produce a sound.

The U.S. Food and Drug Administration (FDA) approved the first blood test that looks for the antibodies against the novel coronavirus that causes COVID-19. This is different than assays that test for presence of the virus—those test to determine if a patient has COVID-19. These new antibody tests determine if the person was exposed to the virus, had COVID-19 and recovered. And it suggests, if positive, that the person is now immune to COVID-19 and can’t get it again.

Research Triangle Park, North Carolina-based Cellex was granted an emergency use authorization (EUA) on its test yesterday.

The test is performed on a blood sample taken from a patient’s vein and can be performed by laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), the Health and Human Services division that oversees clinical diagnostic testing in the United States.

HOUSTON — A University of Houston professor is waiting for FDA approval of a waterproofing solution that he says can shield personal protective equipment such as N95 masks from the droplets that spread COVID-19.

Professor Seamus Curran said he developed the hydrophobic coating in 2011 while testing it on fabrics. He continued creating similar solutions to be used on wood and masonry with his company, Integricote.

When COVID-19 broke out, he felt the coating could help, especially as health care workers warned of a nationwide shortage of personal protective equipment (PPE) such as N95 masks that health care workers wear.
