Tiny alpaca-derived antibodies point to targets preventing viral infection
Using tiny, alpaca-derived, single-domain antibody fragments, Whitehead Institute scientists have developed a method to perturb cellular processes in mammalian cells, allowing them to tease apart the roles that individual proteins play in these pathways. With improved knowledge of protein activity, scientists can better understand not only basic biology but also how disease corrupts cellular function and identify potential therapeutics to rectify these aberrations.

Ongoing monitoring of Legionella in Flint in the wake of the drinking water crisis
Research presented at the ASM Microbe meeting suggests that microbial water quality issues of Flint drinking water are improving, based on recent testing in March 2016, but that continued vigilance is in order. The research, performed by the Flint Water Study team at Virginia Tech, found that levels of DNA markers for Legionella have decreased throughout Flint since October 2015 before the water change, but did confirm that pathogenic forms of the bacteria, including L. pneumophila, were culturable at some sampling points.

New lizard found in Dominican Republic
A University of Toronto-led team has reported the discovery of a new lizard in the Dominican Republic, strengthening a long-held theory that communities of lizards can evolve almost identically on separate islands. The chameleon-like lizard -- a Greater Antillean anole dubbed Anolis landestoyi for the naturalist who first spotted and photographed it -- is one of the first new anole species found in the Dominican Republic in decades.

Breaking out: How black hole jets punch out of their galaxies
New simulations of the jets produced by rotating supermassive black holes in the cores of galaxies show how powerful ones force their way through surrounding gas and drill out of the galaxy, channeling hot gas into the interstellar medium. Weaker jets stall, dumping their hot gas inside and heating up the entire galaxy. Stalled jets may be part of the black hole feedback mechanism that periodically halts inflow of gas feeding the black hole.

Video captures tadpole escape artists in Panama
Although red-eyed tree frog embryos appear helpless within their jelly-coated eggs, they can hatch up to two days ahead of schedule, reacting within seconds to attacks by egg thieves. At the Smithsonian Tropical Research Institute in Panama, scientists used high-speed video to uncover their rapid-hatching secret.

Functional traits of Giant Sequoia crown leaves respond to environmental threats
As many as 2 billion leaves on a sequoia vie for resources. Established leaves that live for up to 20 years draw water up the tree's trunk and send nutrients down, while the trunk amasses wood and survives for thousands of years. The giant sequoia's size is possible in part because its leaves are responsive to environmental changes. Under changing conditions, will giant sequoia groves and other old-growth conifer forests be at heightened risk of degradation?

'Mosh pits' in star clusters a likely source of LIGO's first black holes
Northwestern University astrophysicists have predicted history. They show their theoretical predictions last year were correct: The merger of two massive black holes detected Sept. 14, 2015, could easily have formed through dynamic interactions in the star-dense core of a globular cluster. These binary black holes are born in the cluster's chaotic 'mosh pit,' kicked out of the cluster and then eventually merge into one black hole. LIGO's first detection of colliding black holes is perfectly consistent with the Northwestern model.

Scientists detect second pair of colliding black holes
The new window onto the universe just opened a little bit wider. For the second time in history, an international team of scientists, including Northwestern University astrophysicists and a laser scientist, has detected gravitational waves and a pair of colliding black holes. This time, the gravitational waves resulted in a longer signal, or chirp, providing more data. The higher-frequency gravitational waves from the lower-mass black holes of the second pair better spread across the LIGO detectors' sweet spot of sensitivity.

New gravitational wave observed from second pair of black holes
Gravitational waves from a second pair of colliding black holes has validated the landmark discovery from earlier this year that confirmed Einstein's general theory of relativity. Rochester Institute of Technology scientists contributed to the initial breakthrough and to the second discovery announced today by the Laser Interferometer Gravitational-wave Observatory.

Study offers explanation for why women leave engineering
Women who go to college intending to become engineers stay in the profession less often than men. Why is this? While multiple reasons have been offered in the past, a new study co-authored by an MIT sociologist develops a novel explanation: The negative group dynamics women tend to experience during team-based work projects makes the profession less appealing.

Did gravitational wave detector find dark matter?
When an astronomical observatory detected two black holes colliding in deep space, scientists celebrated confirmation of Einstein's prediction of gravitational waves. A team of astrophysicists wondered something else: Had the experiment found the "dark matter" that makes up most of the mass of the universe?

New study highlights power of crowd to transmit news on Twitter
The tiny fraction of headlines that news editors push out on Twitter draw a large share of eyeballs, but it's the stories recommended by friends that trigger more clicks. In what may be the first independent study of news consumption on social media, researchers at Columbia University and Inria found that reader referrals drove 61 percent of the nearly 10 million clicks in a random sample of news stories posted on Twitter.

How the butterfly got its spots
By tweaking just one or two genes, Cornell University researchers have altered the patterns on a butterfly's wings. It's not just a new art form, but a major clue to understanding how the butterflies have evolved, and perhaps to how color patterns -- and other patterns and shapes -- have evolved in other species.

Homologues temperature of olivine links deformation experiments and rheology of the upper mantle
The homologues temperature of a crystalline material is defined as the ratio between its temperature and the melting (solidus) temperature in Kelvin. The melting temperature of olivine decreases with increasing iron content and water content, and increases with pressure. Here the homologues temperature of olivine is used to compare the creep strength of the upper mantle in different tectonic settings, and to investigate fabric transitions of olivine in deformation experiments and natural samples.

Gravitational waves detected for a second time
On Dec. 26, 2015 scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time. Both of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors -- located in Livingston, Louisiana, and Hanford, Washington -- detected the gravitational wave event, named GW151226. The LIGO Scientific Collaboration (LSC) and the Virgo Collaboration used data from the twin LIGO detectors to make the discovery, which is accepted for publication in the journal Physical Review Letters.

For tropical mayflies, mountain passes are higher indeed
A study led by Colorado State University biologists shows that insect populations in the tropics exhibit a higher number of distinct species than in the Rockies. But the distinctions between those species consist of subtle, genetic differences that aren't readily visible. These are called cryptic species -- by the looks of things identical, but actually genetically distinct.
