No, Vaccinated People Are Not 'Just as Likely' to Spread the Coronavirus as Unvaccinated People
For many fully vaccinated Americans, the Delta surge spoiled what should've been a glorious summer. Those who had cast their masks aside months ago were asked to dust them off. Many are still taking no chances. Some have even returned to all the same precautions they took before getting their shots, including avoiding the company of other fully vaccinated people. Among this last group, a common r

Man Punches Nurse for Giving His Wife the COVID Vaccine "Without His Consent"
Canadian police are searching for a man they say punched a female nurse in the face after she gave his wife the COVID-19 vaccine without his permission. The incident occurred on Monday morning after the man arrived at a pharmacy in Sherbrooke, Quebec, said police spokesperson Martin Carrier to CNN . There he confronted a nurse for vaccinating his wife at the pharmacy "without his consent" and was

In the race to reduce car emissions, don't forget longevity
The debate on green vehicles often focuses on fuel efficiency and alternative fuels, with the transition to fuel alternatives commonly being considered better for the environment the faster it is. A new study shows that keeping and using existing fuel-efficient cars a little longer can actually reduce CO? emissions even with gasoline cars. Thus, a gradual transition and policies that encourage a c

The Best Indie Movies to Watch This Fall
One of the most underrated aspects of the cinemagoing experience comes when you emerge from the theater, turn to the person you came with, and realize they're as excited as you are to talk about what you just saw. Although I missed plenty about going to theaters when they were closed during the pandemic, the absence of those shared moments stands out the most. After a year when most festivals wer

Nuclear receptor NR5A2 negatively regulates cell proliferation and tumor growth in nervous system malignancies [Cell Biology]
Nervous system malignancies are characterized by rapid progression and poor survival rates. These clinical observations underscore the need for novel therapeutic insights and pharmacological targets. To this end, here, we identify the orphan nuclear receptor NR5A2/LRH1 as a negative regulator of cancer cell proliferation and promising pharmacological target for nervous…

O to bR transition in bacteriorhodopsin occurs through a proton hole mechanism [Biophysics and Computational Biology]
Extensive classical and quantum mechanical/molecular mechanical (QM/MM) molecular dynamics simulations are used to establish the structural features of the O state in bacteriorhodopsin (bR) and its conversion back to the bR ground state. The computed free energy surface is consistent with available experimental data for the kinetics and thermodynamics of…

How top-down and bottom-up attention modulate risky choice [Psychological and Cognitive Sciences]
We examine how bottom-up (or stimulus-driven) and top-down (or goal-driven) processes govern the distribution of attention in risky choice. In three experiments, participants chose between a certain payoff and the chance of receiving a payoff drawn randomly from an array of eight numbers. We tested the hypothesis that initial attention…

Bacterial rhamnolipids and their 3-hydroxyalkanoate precursors activate Arabidopsis innate immunity through two independent mechanisms [Plant Biology]
Plant innate immunity is activated upon perception of invasion pattern molecules by plant cell-surface immune receptors. Several bacteria of the genera Pseudomonas and Burkholderia produce rhamnolipids (RLs) from l-rhamnose and (R)-3-hydroxyalkanoate precursors (HAAs). RL and HAA secretion is required to modulate bacterial surface motility, biofilm development, and thus successful colonization…

ATF6 is essential for human cone photoreceptor development [Cell Biology]
Endoplasmic reticulum (ER) stress and Unfolded Protein Response (UPR) signaling promote the pathology of many human diseases. Loss-of-function variants of the UPR regulator Activating Transcription Factor 6 (ATF6) cause severe congenital vision loss diseases such as achromatopsia by unclear pathomechanisms. To investigate this, we generated retinal organoids from achromatopsia patient…

Distinct single-component adjuvants steer human DC-mediated T-cell polarization via Toll-like receptor signaling toward a potent antiviral immune response [Immunology and Inflammation]
The COVID-19 pandemic highlights the importance of efficient and safe vaccine development. Vaccine adjuvants are essential to boost and tailor the immune response to the corresponding pathogen. To allow for an educated selection, we assessed the effect of different adjuvants on human monocyte-derived dendritic cells (DCs) and their ability to…

The discrete-time Kermack-McKendrick model: A versatile and computationally attractive framework for modeling epidemics [Applied Mathematics]
The COVID-19 pandemic has led to numerous mathematical models for the spread of infection, the majority of which are large compartmental models that implicitly constrain the generation-time distribution. On the other hand, the continuous-time Kermack–McKendrick epidemic model of 1927 (KM27) allows an arbitrary generation-time distribution, but it suffers from the…

Edge current and pairing order transition in chiral bacterial vortices [Biophysics and Computational Biology]
Bacterial suspensions show turbulence-like spatiotemporal dynamics and vortices moving irregularly inside the suspensions. Understanding these ordered vortices is an ongoing challenge in active matter physics, and their application to the control of autonomous material transport will provide significant development in microfluidics. Despite the extensive studies, one of the key aspects…

Beyond the hockey stick: Climate lessons from the Common Era [Earth, Atmospheric, and Planetary Sciences]
More than two decades ago, my coauthors, Raymond Bradley and Malcolm Hughes, and I published the now iconic "hockey stick" curve. It was a simple graph, derived from large-scale networks of diverse climate proxy ("multiproxy") data such as tree rings, ice cores, corals, and lake sediments, that captured the unprecedented…

Analysis of SARS-CoV-2 infection dynamic in vivo using reporter-expressing viruses [Microbiology]
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the current COVID-19 pandemic, is one of the biggest threats to public health. However, the dynamic of SARS-CoV-2 infection remains poorly understood. Replication-competent recombinant viruses expressing reporter genes provide valuable tools to investigate viral infection. Low levels of reporter…

Moms and dads shape kids' emotional eating in different ways
New research digs into the interplay between the way parents feed their children and emotional eating by parents and children, as well as the influence the parent's gender has on that association. Most people are familiar with using food as a way to get through a trying time. Known as emotional eating, for some it can be a perfectly appropriate strategy for managing hard feelings, but for others

Dead Space: Hubble Spots Mysterious Ancient Galaxies Running On Empty
(Photo: ALMA (ESO/NAOJ/NRAO)/S. Dagnello (NRAO), STScI, K. Whitaker et al.) In a joint effort with ALMA, the Hubble telescope has discovered six huge, rare, ancient galaxies that date from the universe's most prolific period of star formation. But they're running on empty. These galaxies have run out of the raw material required to form stars, and we don't know why. The galaxies were found as par

Parents want more info about the costs of kids' hospital care
Three-quarters of parents whose children are hospitalized want to talk to a hospital staff member about the projected cost of their child's medical care, but less than 10% of families have such conversations, a new study shows. The finding boosts the argument that patients and their families need better access to financial counselors at hospitals, researchers say. The study, which appears in JAMA

The Atlantic Daily: The Booster-Shot Rollout Is a Mess
Today, a CDC advisory committee weighed in on who should get Pfizer booster shots and made a pretty nuanced recommendation: Americans 65 and older, yes; people who live in nursing homes, yes; people 50 to 64 with an underlying medical condition, yes; people 18 to 49 with an underlying medical condition, it depends. The panel declined to recommend extra shots for health-care workers or people in o
