International Ozone Day

Posted by SIngraffea Sep 4, 2013

ozone_225.jpgJoin the United Nations' call for "A healthy atmosphere, the Future We Want" during the International Day for the Preservation of the Ozone Layer or “Ozone Day.” Celebrated on September 16, it marks the anniversary of the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer. This event highlights issues facing the ozone layer and its role in climate change. It is also a call to action for industries and individuals to participate in protecting our atmosphere from future damage.

Learn about the atmosphere's relationship with climate patterns and weather conditions through Air Masses. Explore the Properties of Air and think about how air pushes on all the surfaces it touches. In the lesson, How We Know What We Know about Our Changing Climate, students are introduced to scientific research on climate change and the role of citizen science in finding solutions. Find out about the environemtal impacts of reactive nitrogen, how humans have been polluting the air with lead since ancient times, and the brown cloud over Asia. Did you know that if earth continues to warm,  massive amounts of carbon could be released when permafrost melts?

To combat these problems, hear how countries are phasing out the use of chemicals to give the ozone hole a chance to heal itself in Ozone Fill-up. Discuss how initiatives like Urban Greening, including Green Roof Designs, are used to improve air quality. Another way to remove ozone from air is through dead skin flakes in dust! The Science Update Ozone-Scrubbing Skin explores how. Find out about Your Carbon Diet and help make changes to be more environmentally and energy friendly. Consider the choices people have to make using Power Up! which examins the trade-offs between different types of power and their enviromental impact.

eyeball.jpgYour eyes are incredible tools that help you explore the world. This month, help raise awareness about the importance of preventing eye injuries, recognizing vision loss, and general eye health for kids. Want to know how your eye works? Take a tour of its anatomy, explore how it takes in light, and how it perceives color. Learn what it means to be nearsighted, how glasses help correct vision, and if reading in the dark leads to problems. Discuss how we use our eyes as measurement tools, test your visual reaction time, and learn how your eyes can be fooled by optical illusions. Ever dealt with red-eye in photos? Learn why that happens and how a flash helps. Did you know that scientists are exploring how we process language by studying people's eye movements? Researchers are also looking at the eye's unique immune response to increase organ transplant tolerance.

A new antibiotic that is effective at killing anthrax and superbug MRSA bacteria could be a weapon in the fight against antibiotic resistance – and terrorism.

 

Anthracimycin, a chemical compound derived from the Steptomyces bacteria, was discovered in the ocean off the coast of Santa Barbara in California. Its unique chemical structure makes it a new addition to the antibiotic family that could pave the way for new drugs.

 

Most new antibiotics are derivatives of existing compounds. The last new naturally-derived antibiotic that entered the market was Daptomycin, a soil-derived compound from Streptomyces roseosporus, approved a decade ago in 2003. It was originally discovered in 1986.

 

"The discovery of truly new antibiotic compounds is quite rare," said William Fenical, Professor of Oceanography and Pharmaceutical Science at the Scripps Institution of Oceanography at UC San Diego, who led the research team.

 

"It's not just one discovery," he said. "It opens up the opportunity to develop analogues – potentially hundreds. Alexander Fleming discovered Penicillin in the 1928 and from that more than 25 drugs were developed. When you find a new antibiotic structure, it goes beyond just one."

 

Follow us!

 

MRSA and anthrax

 

Initial tests suggest that Anthracimycin is particularly potent against MRSA and anthrax, Bacillus anthracis, a lethal bacterial infection that is commonly associated today with outbreaks in livestock and its threat as a biological weapon – particularly after it was deliberately spread in the US mail following the 9/11 attacks in 2001.

 

The team tested the compound on lab mice infected with MRSA – which would have killed within five days. At at 1mg dose per 1Kg of a mouse's weight, it proved effective in eradicating the infection in about 85% of mice.

 

MRSA (meticillin-resistant staphylococcus aureus) can cause life-threatening infections and has been a scourge in hospitals because it is resistant to a number of widely used antibiotics.

 

Antibiotics are highly effective in treating anthrax but it would also possible for terrorists to manufacture a drug resistant strain from known antibiotics, Fenical said. The new discovery could be used by a government to develop an antibiotic that was withheld from public consumption for emergency use.

 

The team has openly published their findings in the German applied chemistry journal Angewandte Chemie for pharmaceutical companies and governments that may be interested in starting research and development (RND) programmes.

Exploring Careers in Space Science

Posted by ric Jun 13, 2013

Space science is more than being stationed on the International Space Station, we know that but too often focus on that as the penultimate goal.  Don't get me wrong, I think the experience would be very cool, and well worth the work it takes to get there.

 

There are so many ways in which one can be active in "space science" - ways that can link ones personal/professional interests to the larger space exploration project.  I recently had a conversation with a nutrition researcher who told me of the amazing research underway to explore the means of feeding humans during extended space flights (like to Mars and beyond).  Of course it makes sense, but too often we forget about these ways in which one becomes part of the space exploration community.

 

A few weeks ago, AAAS sponsored an event that brought some space scientists together for conversations with middle schoolers.  The group included folks who work to share space science stories and discoveries with larger audiences - and in doing so helping others share in the excitement.  These folks also help more lay persons like me to understand the challenges more clearly and, as a result of crowd sourcing like methods, seek out creative solutions to vexing questions.  The panel also included a scientist who is using satellite images from space to document human rights abuses here on earth.  And let's not forget the electrical engineer who works to be sure that all those monitoring stations around the world and in space orbit can talk to one another and to mission control personnel.

 

Each of these folks, and my nutritionist friend, are making contributions that build and strengthen what we know to make space exploration possible and even more exciting.  What a cool life!

jellyfish.jpgWhat do submarines, blood flow, and wind farms have in common? They’ve all benefitted from scientific research by Dr. John Dabiri, who studies jellyfish, of all things! Dr. Dabiri, a researcher at the California Institute of Technology, studies the way jellyfish move through the water. His findings in fluid dynamics and propulsion help design more streamlined submarines for the Navy, more efficient windmills for renewable energy, and solve problems to do with the human cardiovascular system. Watch the video about Dr. Dabiri’s research here, part of a new series by Science NetLinks called Conversations with a Scientist.

 

Another Conversations with a Scientist video features Dr. Michael Brown, an astronomer at the California Institute of Technology, who helped discover notable, planet-like objects in our solar system beyond Pluto. One of these objects—named Eris, after the Greek goddess of chaos and discord—is larger than Pluto, which sparked the heated scientific debate about whether Pluto should in fact be considered a planet, despite there being potentially many undiscovered, larger objects orbiting the sun. As a result of Dr. Brown’s discovery, Pluto was famously demoted to “dwarf planet” status in the scientific community.


To learn more about professional scientists and their careers, check out our What Do Scientists Do? lesson (grades 6–8) and the Secret Life of Engineers and Scientists tool (grades 6–12). Then learn about women scientists in medicine (lesson for grades 9–12) and biology (tool for grades 6–12), African American scientists (lesson for grades 6–8), and Latino/a scientists as well (featuring links to external resources).


If you enjoy Conversations with a Scientist, keep an eye out for lessons and other educational resources relating to these videos, coming soon!

Hurricane Season

Posted by SIngraffea Jun 10, 2013

hurricanerita_225.jpgDid you know that a hurricane (also known as a cyclone or typhoon in other parts of the world) can dump more than 2.4 trillion gallons of rain in a single day? These severe tropical storms form over ocean waters that are warmer than 80 degrees Fahrenheit, usually 5 to 15 degrees latitude north and south of the equator.

The Pacific hurricane season began May 15, while the hurricane season in the Atlantic began June 1 and continues through November. Explore our collection of resources to help your class learn more about the science behind hurricanes, wind, and other weather. Students can investigate the anatomy of a hurricane, discuss how forces change the speed and direction of motion, and look at how technology is used in tracking these types of storms.

Check out Thinkfinity's collection on hurricanes and join the discussion to share what resources you use to explain these forces of nature with your students.


I just posted in the Community Hub about tomorrow's AAAS ScienceLive Chat: Mission to Mars--With Special Guest Buzz Aldrin. We just wanted to make sure that everyone in the All About Science group knew about this event.

 

Details:

June 6th, 3:00pm EDT
