Lightning -- one of the great unsolved mysteries.
A new study in Science investigates the wisdom of crowds... well, schools. Andrew Berdahl, graduate student at Princeton University, explains that Golden shiner minnows prefer shady habitat. And he and his co-authors found that large groups of fish are better at tracking shady habitats than smaller groups or individuals--a demonstration of collective sensing.How do fish pool their senses? The researchers filmed fish and digitized their movement to try to answer the question.
In 2011, comet Lovejoy traveled through the sun's corona and lived to tell the tale. But its tail was the most telling. Reporting in the journal Science, Cooper Downs, an astrophysicist at Predictive Science Inc. in San Diego, Calif., says that the wiggly path of the comet's tail helps explain the sun's magnetic field.
The Rockaways, a Queens, N.Y. neighborhood, is still recovering from Sandy. Debris from fires lingers on the streets, and buildings torn apart by the storm are crumbling on the beach. But at least for those with restored heat and power (7,000 customers in the area are still without power), there is yet another worry: mold. Peter Corless, a community organizer in the Rockaways, gives us a tour of the neighborhood, while Joan Bennett, a mycologist whose house molded after Katrina flooding, describes the species of fungi she found in her own home after that hurricane and in New Jersey homes post-Sandy.

Although we all know that sneezes and coughs transmit infections, little research had been done to model how they work. To address this knowledge gap, Dr. Lydia Bourouiba and Dr. John Bush of MIT's Applied Mathematics Lab used high speed cameras and fluid mechanics to reveal why we've grossly underestimated the role of gas clouds in these violent expirations.

Why do your fingers get pruney after a swim? Only a handful of researchers, including Einar Wilder-Smith, Mark Changizi, and Tom Smulders, have looked into the phenomenon. Publishing in Biology Letters, Smulders lends a hand to the hypothesis, set forth by Changizi and colleagues, that finger wrinkles improve our grip of wet objects.

As a choreographer who often collaborates with dancers with disabilities, Merry Lynn Morris has long thought that traditional manual and power wheelchair designs were constraining. Her work in integrative dance, along with her experience growing up with a father who relied on a wheelchair, inspired her to invent a power wheelchair designed for artistic expression. Equipped with omnidirectional movement, a rotating seat, and a hands-free control, the chair enables dancers to explore new movement techniques, and may one day provide greater mobility in everyday life, too.

Up and down the West coast of the U.S., bees are leaving their hives, flying around at night and then suddenly dropping dead. Learn all about this parasitic horror that quietly zombifies these insects and how you can become a real-life zombee hunter.
Ice can be hard to get a handle on, literally and figuratively. It can be cloudy or clear, as hard as concrete or as soft as a snowflake. Ice experts Erland Schulson, head of the Ice Research Lab at Dartmouth College, and Shintaro Okamoto, founder of Okamoto Studio in Queens, New York, have staked their livelihoods on the slippery material. We asked them what fascinates them about frozen water. (Originally published Jan 27, 2012)
Science Friday salutes a great science teacher. "Office hours are some of my favorite hours of the week," says professor Tom Carlson, a medical doctor, ethnobotanist and instructor of 1700 students annually at the University of California, Berkeley. One of Carlson's former students, SciFri associate senior producer Christopher Intagliata, told us that Carlson's class was the reason he got into science.

For honey bees, making is a new queens is a simple as adding royal jelly, a unique protein rich secretion, to the cell of a growing larvae. This fairly well studied addition causes a cascade of physiological changes in the growing larvae and voila! A queen is born. However, what causes a baby bumblebee (the fuzzier and more weather-hardy cousins to honey bees) to become royalty remains a mystery. They don’t produce royal jelly but they produce a unique barf for their young. Enter entomologist Hollis Woodard and her students at UC Riverside who hope that by understanding how queens are created, they can mitigate on-going extinction crises in bumblebees species. Woodard and company begin by heading up to San Bernardino mountains outside Los Angeles. Here, the researchers collect emerging queens as they buzz around the blooming Manzanita shrubs. These queens are brought back to the lab, where the establish their own (see through) honeypots. Lavished with food by the lab members, the queens lay dozens of larvae which become daughter drones. These drones are then “milked” for their barf which is analyzed for its chemical properties. Future larvae are hand fed the analyzed barf in various quantities and intervals to determine what factors lead to the generation of queen bees.

Researchers are on a quest to find the lake trout that remain in Lake Michigan.
Dieu, c'est toi mon Dieu, je te cherche, mon âme a soif de toi, après toi languit ma chair, terre sèche, altérée, sans eau.
Oui, au sanctuaire je t'ai contemplé, voyant ta puissance et ta gloire.
Meilleur que la vie, ton amour; mes lèvres diront ton éloge.
Oui, je veux te bénir en ma vie, à ton nom, élever les mains;
comme de graisse et de mœlle se rassasie mon âme, lèvres jubilantes, louange en ma bouche.
Quand je songe à toi sur ma couche, au long des veilles je médite sur toi,
toi qui fus mon secours, et je jubile à l'ombre de tes ailes;
mon âme se presse contre toi, ta droite me sert de soutien.
Mais ceux qui poussent mon âme à sa perte, qu'ils descendent au profond de la terre!
Qu'on les livre au tranchant de l'épée, qu'ils deviennent la part des chacals!
Et le roi se réjouira en Dieu; qui jure par lui en tirera louange quand les menteurs auront la bouche fermée.
Nothing can ever come between us and the love of God, the love of God revealed to us in Christ Jesus.

Antienne: Criez de joie pour le Seigneur, terre entière; dans nos cœurs sa louange toujours.
Heureux le peuple dont le Seigneur est le Dieu,
la nation qu'il s'est choisie en héritage ;
du haut des cieux le Seigneur regarde,
il voit chacun des fils d'Adam.
Du lieu de sa demeure il observe
tous les habitants de la terre,
lui qui forme le cœur de chacun,
lui qui discerne tous leurs actes.
Le Seigneur a les yeux sur ses fidèles,
sur ceux qui espèrent son amour,
pour préserver leur âme de la mort,
les faire vivre au temps de la famine.
Notre âme attend le Seigneur,
notre secours et bouclier c'est lui ;
en lui, la joie de notre cœur,
en son nom de sainteté, notre foi.

Sauve-nous, Seigneur, notre Dieu, rassemble-nous du milieu des nations.
Save us, O Lord, our God: and gather us from among nations.
Spasi nas, Gospodine, Bože naš, i saberi nas od bezbožnih naroda.
Salvaci, Signore Dio nostro, e raccoglici di mezzo ai popoli.
Salvos nos fac, Domine Deus noster, et congrega nos de nationibus.
Sálvanos, Señor y Dios nuestro; congréganos de entre las naciones.
上主，我們的天主，求你拯救我們，由異民召回我們重逢.

Special prayer in the occasion of the Week of Prayer for Christian Unity, Taizé, Wednesday, 18 January 2017
Celui qui demeure sous l'abri du Très-Haut Repose à l'ombre du Tout Puissant.
Je dis à l'Eternel: Mon refuge et ma forteresse, Mon Dieu en qui je me confie!
Car c'est lui qui te délivre du filet de l'oiseleur, De la peste et de ses ravages.
Il te couvrira de ses plumes, Et tu trouveras un refuge sous ses ailes; Sa fidélité est un bouclier et une cuirasse.
Tu ne craindras ni les terreurs de la nuit, Ni la flèche qui vole de jour,
Ni la peste qui marche dans les ténèbres, Ni la contagion qui frappe en plein midi.
Que mille tombent à ton côté, Et dix mille à ta droite, Tu ne seras pas atteint;
De tes yeux seulement tu regarderas, Et tu verras la rétribution des méchants.
Car tu es mon refuge, ô Eternel! Tu fais du Très-Haut ta retraite.
Aucun malheur ne t'arrivera, Aucun fléau n'approchera de ta tente.
Car il ordonnera à ses anges De te garder dans toutes tes voies;
Ils te porteront sur les mains, De peur que ton pied ne heurte contre une pierre.
Tu marcheras sur le lion et sur l'aspic, Tu fouleras le lionceau et le dragon.
Puisqu'il m'aime, je le délivrerai; Je le protégerai, puisqu'il connaît mon nom.
Il m'invoquera, et je lui répondrai; Je serai avec lui dans la détresse, Je le délivrerai et je le glorifierai.
Je le rassasierai de longs jours, Et je lui ferai voir mon salut.
En ma bouche il a mis un chant nouveau: louange à notre Dieu.
He put a fresh song in my mouth, praise of our God.
U usta mi stavi pjesmu novu, slavopoj Bogu našemu.
Mi ha messo sulla bocca un canto nuovo, lode al nostro Dio.
Puso en mi boca un canto nuevo, un himno a nuestro Dios.
Et immisit in os meum canticum novum, carmen Deo nostro.
他將新歌置於我口，為讚美我們的天主.
Ps 40,4

En ma bouche il a mis un chant nouveau: louange à notre Dieu.
J'espérais le Seigneur d'un grand espoir, il s'est penché vers moi, il écouta mon cri. Louange.
Mon Dieu, j'ai voulu ta loi au profond de mes entrailles. Louange.
J'ai annoncé la justice du Seigneur dans la grande assemblée. Louange.
Gloire au Père, et au Fils, et au Saint-Esprit. En ma bouche.
