With Genetic Tweak Maize Cells Produce Enzyme-Replacement Drug

waxy-maize

Some complex protein drugs need to be made by culturing mammalian cells. Plant biologists have developed a way to manufacture the necessary enzymes for drugs in maize. The scientists published their findings in the journal Nature Communications. Plant biologist Allison Kermode, at Simon Fraser University in Burnaby, Canada, whose husband works with people who have […]

Projections of Urban Growth Highlight at Risk Areas

urban-city-sprawl

Researchers are trying to make detailed predictions about how urban areas are likely to grow in order to forecast how the next few decades of urbanization will affect biodiversity. The scientists published their findings in the journal Proceedings of the National Academy of Sciences. The biggest changes are currently occurring in developing countries. The UN […]

Lens-Free System Shows Spiraling Swimming Pattern of Human Sperm

image-sperm-head-chip

A new three-dimensional imaging technique has shown the spiraling movements that human sperm accomplishes while swimming. Previously, these movements had only been inferred from two-dimensional data. The scientists published their findings in the journal Proceedings of the National Academy of Sciences. The high-resolution recordings in three dimensions tracked more than 1,500 cells over several hours. […]

Precise Determination of the Weight of Ocean Will Help Model Sea Level Rise

ocean-sea-level-rise

If scientists are able to figure out the precise weight of the world’s oceans it will allow them to model changes in the sea level more accurately. With the record ice melt this past summer, it would help ensure the safety of the cities on the coastlines that are vulnerable to any rise of the […]

Russian Impact Crater Might Contain Trillions of Carats of Diamonds

Popigai crater

On Monday, Novosibirsk scientists of the Institute of Geology and Mineralogy at the Siberian Branch of the Russian Academy of Sciences announced that there is a huge deposit of diamonds buried under an impact crater in Siberia. These diamonds are twice as hard as normal because of their origin. The trillions of carats are located […]

West Nile Virus Might Be Linked to Kidney Problems

west-nile-virus

As of September of this year, there have been more than 2,600 new cases of West Nile virus in the USA, including 118 deaths, which were reported to the CDC in Atlanta, Georgia. While most people have no symptoms of West Nile, some have life-threatening brain inflammation, which leaves survivors with long-term disabilities including paralysis […]

DARPA’s CT2WS Program Improves Target Detection

CT120 Camera

Launched in 2008 to improve the ability to detect threats from standoff distances, DARPA’s CT2WS program uses human brainwaves, improved sensors, and cognitive algorithms to improve visual threat detection, identifying up to 91 percent of targets during testing with extremely low false-alarm rates and widening a warfighter’s field of view to 120 degrees. For warfighters […]

Improved Estimates of DNA’s Mutation Rate Paint Clearer Picture of Human Prehistory

reconstruction-homo-heidelbergensis

Since the 1960s, DNA has changed the story of human ancestry. Some studies have shown that all modern humans are descended from ancestors who lived in Africa 100,000 years ago. Some new findings suggest that key events in human evolution contradict archeology. Estimates of DNA’s mutation rate work like a molecular clock that underpins genetic […]

Overcoming Barriers to Stem Cell-Based Regenerative Medicine

colony of induced pluripotent stem cells

In a newly published paper, a team of researchers from the Salk Institute for Biological Studies and their collaborators at UC San Diego found that there is a consistent signature difference between embryonic and induced pluripotent stem cells; findings that could help implement the use of induced stem cells in regenerative medicine. La Jolla, California […]

Arctic Sea Ice Melt Might Spur Extreme Weather Conditions in Europe

extreme-winter

This year, the Arctic sea experienced a record ice melt during the summer and this might mean that northern Europe will experience a frigid winter. In the past years, when there was a lot of ice melt, there were bad winters. Jennifer Francis, a researcher at Rutgers University, states that they can’t make any certain […]

Understanding the Evolution of Organic Molecules in our Solar System

Researchers mimic materials at the edge of our solar system

A newly published study from scientists at NASA’s Jet Propulsion Laboratory provides the first direct look at the organic chemistry that takes place on icy particles in the frigid reaches of our solar system. Would you like icy organics with that? Maybe not in your coffee, but researchers at NASA’s Jet Propulsion Laboratory in Pasadena, […]

Room-Temperature Superconductivity Might Have Been Attained

boron-doped-carbon

Material scientists in Germany have claimed that they have discovered a material that can act at a superconductor at room temperature. If this is accurate, then there could be huge potential energy savings since superconductors transmit electricity with zero resistance. Until now, the superconductors work at temperatures of about -110°C and lower. The scientists have […]

Dark Energy Camera Captures its First Images

first images captured by the Dark Energy Camera

Located on a mountaintop in Chile, the newly-constructed Dark Energy Camera is the most powerful sky-mapping machine ever created and has captured and recorded its first rays of light from distant galaxies. When the Dark Energy Camera (DECam) opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, […]

Unlike the popular belief that sleeping more on the weekends can help sleep deprived people catch up on sleep, a new sleep study has shown that sleeping in on the weekends will make you sleepier come Monday morning. The scientists announced their findings through UT Southwestern.  A great myth of sleep deprivation is that if […]

Prevalence of Multi-Drug Resistant E. Coli Rising ICAAC 2 Reports

Ecoli-close-up

Infections with multi-drug resistant E. coli, which is also known as ESBL (extended spectrum beta-lactamase), have been assumed to be a hospital phenomenon. A recent analysis presented at The Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) surveyed records from five hospital across the USA (New York, Pennsylvania, Michigan, Texas, and Iowa) and identified 291 […]

Probable Distance to Remnant of Kepler’s Supernova

An image of the Kepler supernova remnant

Scientists at CfA have taken an important step in determining the distance of the remnant of Kepler’s supernova, concluding that the remnant distance is probably greater than about twenty-one thousand light-years. Supernovae, the explosive deaths of massive stars, are among the most momentous events in the cosmos because they disburse into space all of the […]
