Data from the Jan. 19 in-flight launch escape demonstration of SpaceX’s Crew Dragon spacecraft indicate the performance of the capsule’s SuperDraco abort engines was “flawless” as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about 3.3Gs, officials said Thursday.

The Jan. 19 test demonstrated the Crew Dragon’s ability to safely carry astronauts away from a launch emergency, such as a rocket failure, and return the crew to a parachute-assisted splashdown in the Atlantic Ocean.

For its final full-scale test before astronauts ride it into space, the Crew Dragon spacecraft lifted off at 10:30 a.m. EST (1530 GMT) on Jan. 19 from pad 39A at the Kennedy Space Center in Florida. A Falcon 9 rocket carried the capsule aloft — just as it would on a crewed mission — for the first 85 seconds of the mission.

To get greater efficiency, Google DeepMind’s researchers did what chip designers have long done, built a pipeline so that the learning rule for machine learning — backpropagation — is more efficient.

Oozing with poison and small enough to fit in a petri dish, the organoids could one day help provide sorely-needed antivenoms.

In a 24–10 vote, the House Judiciary Committee approved a bill that would effectively end marijuana prohibition on Wednesday. The Marijuana Opportunity Reinvestment and Expungement (MORE) Act of 2019, or H.R. 3884, was introduced by House Judiciary Committee Chairman Jerrold Nadler (D-NY) and currently has 55 co-sponsors. This is the first time that a congressional committee has approved a bill to make cannabis legal. The MORE Act would federally decriminalize cannabis by removing it from the Controlled Substances Act, and would require the expungement of past federal cannabis convictions.

The bill would also establish a Cannabis Justice Office to administer a program to reinvest resources in the communities that have been most detrimentally impacted by prohibition, funded by a 5% tax on state-legal cannabis commerce.

Moreover, it will allow the Small Business Administration to provide loans and grants to cannabis-related businesses and support state and local equity licensing programs, and would permit doctors within the Veterans Affairs system to recommend medical cannabis to patients in accordance with applicable state laws.

Optimism bias, i.e. expecting the future to hold more desirable than undesirable outcomes, also extends to people that we like or admire. However, it remains unknown how the brain generates this social optimism bias. In this study, respondents estimated the likelihood of future desirable and undesirable outcomes for an in-group and three out-groups: warm-incompetent, cold-competent, and cold-incompetent. We found a strong social optimism bias for the in-group and the warm out-group and an inverted pattern for the cold-incompetent out-group. For all groups, scores of social optimism bias correlated with the brain activity in structures that respondents differentially engaged depending on the target social group. In line with our hypotheses, evaluating the in-group recruited the ventromedial prefrontal cortex and the precuneus/posterior cingulate cortex, whereas evaluating the warm out-group engaged the posterior insula, mid cingulate cortex, and somatosensory cortices. These findings suggest different underlying cognitive mechanisms of social optimism bias for these groups, despite similar behavioural patterns. Thinking about the cold out-groups recruited the right anterior temporal lobe, and temporoparietal junction. Evaluating the cold-incompetent out-group additionally recruited the anterior insula, inferior frontal cortex and dorsomedial frontal cortex. We discuss these neuroimaging findings with respect to their putative cognitive functions.

Researchers say the virus spreading through China is in the same family as SARS and closest to one found in bats. Discovery: Today, researchers led by Zheng-Li Shi at the Wuhan Institute for Virology posted a paper describing the virus in detail for the first time, including a picture of the virus infecting cells. The new virus, dubbed nCoV-2019, is in the same family as SARS—a coronavirus that caused global mayhem starting in 2003—and even uses the same receptor to hack into a person’s lung cells, Li’s team found.
