Scientists discover planet orbiting closest single star to our Sun

Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered an exoplanet orbiting Barnard’s star, the closest single star to our Sun. On this newly discovered exoplanet, which has at least half the mass of Venus, a year lasts just over three Earth days. The team’s observations also hint at the existence of three more exoplanet candidates, in various orbits around the star. Located just six light-years away, Barnard’s star is the second-closest stellar system — after Alpha Centauri’s three-star group — and the closest individual star to us. Owing to its proximity, it is a primary target in ...

Immigrants to the United States still assimilate

Children of immigrants to the United States typically incorporate themselves into US economic and cultural life, and this pattern of assimilation has not markedly changed in over a century. Today, one in seven US residents was born abroad, rates similar to those seen in the late nineteenth century. As immigrants’ countries of origin have shifted from Europe to Asia and the Americas, a narrative has developed that contemporary immigrants do not assimilate as thoroughly as older immigrants. But is this true? In a Perspective, Ran Abramitzky and Leah Boustan summarize their long-running research program matching individuals across historical US Censuses. The authors compare ...

Vaccinating the young to save the old in the Tropics

A model suggests that vaccinating children and teens against the flu can help protect the elderly in tropical countries. Influenza kills up to 650,000 people worldwide every year. In part due to the lack of strong seasonality and differences in vaccine supply, optimal vaccination strategies for the tropics may differ from those in temperate zones. Joseph Servadio and colleagues parameterized an age-structured mathematical model of influenza transmission to the asynchronous, non-annual epidemiology of tropical influenza in Vietnam, a country with low vaccine coverage. The model includes three subtypes of the flu virus. Vaccinating year-round was found to be ...

Climate change, drought, dust, and plankton blooms

A study links an unusual plankton bloom off the coast of Madagascar to drought in Southern Africa. Climate warming has intensified droughts around the world. When vegetation dies from lack of water, the wind can pick up and carry unprotected soil particles for thousands of kilometers. These dust particles can then act as fertilizer when deposited in seawater. Dionysios Raitsos and colleagues show that dust from drought-stricken Southern Africa caused a bloom of marine phytoplankton off the southeast Madagascar coast from November 2019 through February 2020. The team used standardized anomalies of dust aerosol optical depth from the Copernicus ...

Nudges fail to reduce online hate

Seven nudges aiming to reduce hateful speech online all failed—but the nudges unexpectedly succeeded in increasing engagement with harmless and wholesome content. Controlling hate speech is an ongoing challenge for online communities. In a pre-registered experiment, Tatiana Celadin and colleagues compared the effects of seven “nudges,” messages designed to promote prosocial behaviors: reminding posters of descriptive norms, injunctive norms, or personal norms; cooling down negative emotions; stimulating deliberation or empathy; and highlighting reputation. Over 4,000 Americans recruited through the online platform ...

NMR-guided optimization of lipid nanoparticles for enhanced siRNA delivery

Small interfering RNA (siRNA) molecules hold immense potential for treating diseases by silencing specific genes. Encapsulated in lipid nanoparticles (LNPs), siRNA can be delivered efficiently to target cells. However, the effectiveness of these therapies hinges on the internal structure of the LNPs, which can significantly impact their ability to deliver siRNA. Traditional methods often fall short in providing the detailed molecular insights needed to fine-tune LNP design for optimal therapeutic efficacy. A study published in the Journal of Controlled Release on August 02, 2024, led by Assistant Professor Keisuke Ueda from ...

Women more likely to choose wine with feminine labels

PULLMAN, Wash. – To appeal to the majority of consumers, winemakers may want to pay as much attention to what’s on the bottle as what’s in it. A three-part experimental study led by Washington State University researchers found that women were more inclined to purchase wine that had labels with feminine gender cues. The more strongly the participants identified with other women, a phenomenon called “in-group identification,” the greater this effect was. A feminine label also influenced their expectation that they would like the wine better. With women representing 59% ...

Solidarity drives online virality in a nation under attack, study of Ukrainian social media reveals

While divisive social media posts get more traction in countries such as the US, a new study shows that celebrating national unity is the way to go viral in Ukraine. “Ingroup solidarity” statements got far more likes and shares than hostile posts about Russians – a trend that only grew stronger in the wake of the invasion. The first major study of social media behaviour during wartime has found that posts celebrating national and cultural unity in a country under attack receive significantly more online engagement than derogatory posts about the aggressors.   University of Cambridge psychologists analysed a total of 1.6 million ...

Maybe we shouldn’t even call low-grade prostate cancer “cancer”

A new paper in the Journal of the National Cancer Institute, published by Oxford University Press, indicates that patients may benefit if doctors stop calling certain early-stage changes to the prostate “cancer” at all. Prostate cancer is the second leading cause of cancer death worldwide in men, but far more patients are diagnosed than die of the disease. In 2022, there were nearly 1.5 million cases of prostate cancer, but only 400,000 deaths. Low-grade prostate cancer, commonly known as GG1 among physicians, virtually never metastasizes or causes symptoms. Some medical researchers have wondered recently if it would be a benefit ...

‘Cheeky’ discovery allows scientists to estimate your risk of dying using cells found in the mouth

We don’t all age at the same rate. But while some supercentenarians may age exceptionally slowly due to winning the genetics jackpot, a plethora of behavioral and lifestyle factors are known to speed up aging, including stress, poor sleep, poor nutrition, smoking, and alcohol. Since such environmental effects get imprinted on our genome in the form of epigenetic marks, it is possible to quantify molecular aging by characterizing the epigenome at prognostic genomic sites. Over the past decade, scientists have developed several such ‘epigenetic clocks’, calibrated against chronological age and various lifestyle factors across large ...
