Arctic Ocean methane does not reach the atmosphere

250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate gas rising up through the sea reaches the atmosphere.

Faster, more efficient CRISPR editing in mice

Creating transgenic mice, while critical to biomedical research, is laborious and expensive, despite improvements since the advent of CRISPR-Cas9 gene editing. Now, UC Berkeley biologists have invented a technique that simplifies, improves and lowers the cost of generating knockout mice. They discovered that electroporation can move CRISPR-Cas9 molecules into mouse embryos with nearly 100 percent efficiency, much better than the success from microinjecting Cas9 mRNA and guide RNA. The gene-editing success is also higher.

3-D model reveals how invisible waves move materials within aquatic ecosystems

Garbage, nutrients and tiny animals are pushed around, suspended in the world’s oceans by waves invisible to the naked eye according to a new 3-D model developed by mathematicians at the University of Waterloo.David Deepwell, a graduate student, and Professor Marek Stastna in Waterloo’s Faculty of Mathematics have created a 3-D simulation that showcases how materials such phytoplankton, contaminants, and nutrients move within aquatic ecosystems via underwater bulges called mode-2 internal waves.

Rethinking hospital alarms

On average, there are about 480,000 patients in hospitals in the US — each generating about 135 clinical alarms per day. But studies show that more than 90 percent of these alarms result in no action, and alarm errors occur roughly 8 million times per day. During the ASA 171st meeting, Ilene Busch-Vishniac, an acoustical consultant, will present a model that predicts how often alarm errors will occur based on several recent studies of hospital alarms.

Fungi — a promising source of chemical diversity

The fungus Aspergillus fumigatus produces a group of previously unknown natural products. With reference to plant isoquinoline alkaloids, these substances have been named fumisoquins. Researchers from Jena (Germany) and the USA discovered the novel substances while studying the fungal genome. This study shows that fungi and plants developed biosynthetic pathways for these complex molecules independently of each other. These findings make Aspergillus an interesting target for the discovery of novel drugs and their biotechnological production.

Scientists disagree over Zika risk at Brazil’s Olympics

Material to prevent Zika infection by mosquitoes are displayed at the 68th World Health Assembly at the UN in GenevaOne day after a top U.S. health official declared there was no public health reason to cancel or delay this summer's Olympics in Brazil, more than 150 scientists on Friday called for just that, saying the risk of infection from the Zika virus is too high. The scientists, many of them bioethicists, who signed an open letter published online to Dr. Margaret Chan, director-general of the World Health Organization. The letter urged that the Games, due to be held in Rio de Janeiro in August, be moved to another location or delayed.

NASA to make second attempt at inflating space station test module

The unexpanded BEAM is seen attached to the Tranquility module on the International Space StationBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – Astronauts aboard the International Space Station will try again on Saturday to inflate a novel experimental habitat after the fabric module failed to unfurl as planned earlier this week, NASA officials said on Friday. The Bigelow Expandable Activity Module, or BEAM, was unpacked 10 months later than expected due to launch delays, manufacturer Bigelow Aerospace told reporters on a conference call. The impact was likely most serious on the outer layers, said Lisa Kauke, BEAM deputy program manager at Bigelow.

Rosetta spacecraft finds key building blocks for life in a comet

Handout of the Rosetta comet being studied by Europe's orbiting Rosetta spacecraftBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – Scientists for the first time have directly detected key organic compounds in a comet, bolstering the notion that these celestial objects delivered such chemical building blocks for life long ago to Earth and throughout the solar system. The European Space Agency's Rosetta spacecraft made several detections of the amino acid glycine, used by living organisms to make proteins, in the cloud of gas and dust surrounding Comet 67P/Churyumov-Gerasimenko, scientists said on Friday. Glycine previously was indirectly detected in samples returned to Earth in 2006 from another comet, Wild 2.

Can Stomach Botox Injections Help People Lose Weight?

Doctors are considering a new use for Botox: The drug may help obese people lose weight, according to early research. In addition, researchers in earlier studies assumed that Botox, which relaxes muscles, would help people lose weight because it would slow down the rate that the stomach empties itself.

Vaping Could Make Medical Pot Healthier

A new type of smoking called “cannavaping” — using e-cigarettes for vaping cannabis — may help people use marijuana for medical reasons, according to a small, early study. Smoking conventional marijuana cigarettes may lead a person to inhale high amounts of the toxic contaminants that are released when marijuana is burned, the researchers said. In contrast, cannavaping might provide a way to avoid inhaling high levels of these contaminants, the researchers said.

Radar images reveal Mars is coming out of an ice age

A undated simulated 3-D perspective view of MarsBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – An analysis of radar images that peered inside the polar ice caps of Mars shows that Earth's neighbor is coming out of an ice age that is part of an ongoing cycle of climate change, scientists said on Thursday. The Martian ice began its retreat about 370,000 years ago, marking the end of the last ice age, according to the research published in the journal Science. Using images taken by satellites orbiting Mars, the researchers determined that about 20,872 cubic miles (87,000 cubic km) of ice has accumulated at its poles since the end of the ice age, mostly in the northern polar cap.

Scientists: Underground stone rings made by Neanderthals

This is an undated image released by CNRS on Wednesday May 25, 2016 of stone rings inside a cave on Bruniquel in France. Scientists say that a pair of mysterious stone rings found deep inside a French cave was probably built by Neanderthals about 176,500 years ago, proving that our ancient cousins were capable of more complex behavior than previously thought. The structures were made from hundreds of column-shaped mineral deposits, called stalagmites, that were chopped to a similar length and laid out in two oval patterns up to 40 centimeters (16 inches) inches high. (Michel Soulier/CNRS via AP)BERLIN (AP) — Two mysterious stone rings found deep inside a French cave were probably built by Neanderthals about 176,500 years ago, proving that the ancient cousins of humans were capable of more complex behavior than previously thought, scientists say.
