Rare supernova discovery ushers in new era for cosmology

Mié, 04/19/2017 - 22:00
With from an automated supernova-hunting pipeline based at NERSC, astronomers have captured multiple images of a gravitationally lensed Type 1a supernova. This detection is currently the only one of its kind, but astronomers believe that if they can find more they may be able to measure the rate of the Universe's expansion within four percent accuracy. Fortunately, two Berkeley Lab researchers do have a method for identifying more of these events using existing wide-field surveys.

Using venomous proteins to make insect milkshakes

Mié, 04/19/2017 - 22:00
In a just-published paper in the journal PLOS Pathogens, Adler Dillman, an assistant professor at the University of California, Riverside and several collaborators found that nematodes secrete a deadly cocktail of proteins to kill many insects that damage crops. The finding overturns a long-held belief that it is exclusively bacteria, working in conjunction with nematodes, that kill the insects.

BP oil spill did $17.2 billion in damage to natural resources, scientists find

Mié, 04/19/2017 - 22:00
The 2010 BP Deepwater Horizon oil spill did $17.2 billion in damage to the natural resources in the Gulf of Mexico, a team of scientists recently found after a six-year study of the impact of the largest oil spill in US history.

Study: Accomplished female scientists often overlooked

Mié, 04/19/2017 - 22:00
Invited speakers at neuroimmunology conferences in 2016 were disproportionately male, and not because male scientists were producing higher quality work, according to a new study from Washington University School of Medicine in St. Louis. Instead, a review of papers published in high-impact journals showed that qualified female scientists were overlooked by organizing committees.

Scientists uncover details on the rise of a tick-borne disease on Long Island

Mié, 04/19/2017 - 22:00
Scientists at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health report elevated levels of a pathogen responsible for the tick-borne disease babesiosis in Suffolk County, New York, where rates are the highest in the state. Results are published in the journal mSphere.

High performance computing researcher Shuaiwen Leon Song asked if hardware called 3-D stacked memory could do something it was never designed to do -- help render 3-D graphics.

Risk of psychosis from cannabis use lower than originally thought, say scientists

Mié, 04/19/2017 - 22:00
Scientists at the University of York have shown that the risk of developing psychosis, such as hallucinations, from cannabis use is small compared to the number of total users.

Finding order and structure in the atomic chaos where materials meet

Mié, 04/19/2017 - 22:00
Materials science researchers have developed a model that can account for irregularities in how atoms arrange themselves at the so-called 'grain boundaries' -- the interface where two materials meet. By describing the packing of atoms at these interfaces, the tool can be used to help researchers determine how grain boundaries affect the properties of metal alloys and other materials.

Bacteria used to fight antimicrobial contamination of soil and water

Mié, 04/19/2017 - 22:00
A new study at the University of Nevada, Reno has found a potential way to reduce the environmental presence of Triclosan, an antimicrobial that is also linked to problems with antibiotic resistance.

Mié, 04/19/2017 - 22:00
In a collaborative study, a team of researchers found that radio advertising for free ultrasounds in rural Uganda increased the number of pregnant women who attended modern medical care by 490 per cent.

New research unlocks forests' potential in climate change mitigation

Mié, 04/19/2017 - 22:00
For the first time, scientists have created a global map measuring the cooling effect forests generate by regulating the exchange of water and energy between the Earth's surface and the atmosphere. The information offers a valuable new tool in efforts to mitigate climate change, according to an article recently published in the journal Nature Climate Change.

NASA sees the end of ex-Tropical Cyclone 02W

Mié, 04/19/2017 - 22:00
NASA-NOAA's Suomi NPP satellite spotted the remnants of Tropical Cyclone 02W southeast of Taiwan in the Northwestern Pacific Ocean as the system was dissipating.

Mass. General researchers provide evidence linking 'leaky gut' to chronic inflammation

Mié, 04/19/2017 - 22:00
With the help of genetically engineered mice, scientists at the Massachusetts General Hospital are moving closer to establishing the role that increased intestinal permeability, sometimes called a 'leaky gut,' plays in chronic inflammatory conditions.

AGU journal commentaries highlight importance of Earth and space science research

Mié, 04/19/2017 - 22:00
The American Geophysical Union (AGU) today published a collection of 27 essays as commentaries in its scientific journals highlighting the important role Earth and space science research plays in society.

AATS issues new consensus statement for treatment of empyema

Mié, 04/19/2017 - 22:00
To better manage empyema in the face of rising demand for treatment, the American Association for Thoracic Surgery (AATS) Guidelines Committee called for the formation of the Empyema Management Guidelines Working Group. The group was tasked with analyzing the latest literature about empyema and issuing new evidence-based clinical guidelines. The resulting Consensus Statement is published in The Journal of Thoracic and Cardiovascular Surgery.

IUPUI scientists find risk of lead exposure comes from both ends of firearms

Mié, 04/19/2017 - 22:00
Risks from firearms actually come from both ends of the barrel, according to an Indiana University-Purdue University Indianapolis study. Individuals at firing ranges are exposed to very high amounts of lead from shooting firearms, and exposure is as high at outdoor firing ranges as it is at indoor ranges.
