Two New Permanent Exhibits Open At Maryland Science Center
Posted by Genevieve Klien in categories: energy, science
BALTIMORE (WJZ) — Two new permanent exhibits just opened at the Maryland Science Center, capturing the imagination of children of all ages.
The two new exhibits are titled “Science Aglow” and “Water Play.”
Science Aglow is an exhibit on the Electromagnetic Spectrum. It was developed and built in-house, involving topics of light, radiation, energy and optics. Kids can capture their shadow, use infrared cameras, experiment with light sensors, and observe how different animals view light.

Ocean acidification a challenge for science, governments & communities
Posted by Bill Kemp in categories: economics, science
A new IMAS-led paper published in the science journal Nature Climate Change has highlighted the challenges faced by scientists, governments and communities as rising levels of CO2 are absorbed by the world’s oceans.
Researchers have found that in recent centuries surface ocean pH has fallen ten times faster than in the past 300 million years and that impacts are being felt on ecosystems, economies and communities worldwide.
The economic cost to coral reefs, wild fisheries and aquaculture alone of the process known as Ocean Acidification is projected to reach more than US $300 billion per annum.

NASA director reverses on climate change, after 1 month
Posted by Philip Raymond in categories: astronomy, climatology, education, environmental, ethics, existential risks, governance, government, lifeboat, science, space, sustainability
For millennia, our planet has sustained a robust ecosystem; healing each deforestation, algae bloom, pollution or imbalance caused by natural events. Before the arrival of an industrialized, destructive and dominant global species, it could pretty much deal with anything short of a major meteor impact. In the big picture, even these cataclysmic events haven’t destroyed the environment—they just changed the course of evolution and rearranged the alpha animal.
But with industrialization, the race for personal wealth, nations fighting nations, and modern comforts, we have recognized that our planet is not invincible. This is why Lifeboat Foundation exists. We are all about recognizing the limits to growth and protecting our fragile environment.
Check out this April news article on the US president’s forthcoming appointment of Jim Bridenstine, a vocal climate denier, as head of NASA. NASA is one of the biggest agencies on earth. Despite a lack of training or experience—without literacy in science, technology or astrophysics—he was handed an enormous responsibility, a staff of 17,000 and a budget of $19 billion.
In 2013, Bridenstine criticized former president Obama for wasting taxpayer money on climate research, and claimed that global temperatures stopped rising 15 years ago.

New Liberty Science Center exhibit puts you in the distracted driver’s seat
Posted by Genevieve Klien in categories: mobile phones, science, transportation, virtual reality
After living through a car accident, I think this raises excellent awareness!
Exhibits at the Liberty Science Center in Jersey City usually produce awe and wonder. A new interactive exhibit at LSC, however, gives the participant a grim and horrific look at the results of distracted driving. The AT&T 2018 It Can Wait Tour, a 3D virtual reality exhibit, will be at the science center from Friday, July 6 to through Tuesday, July 10, from 10 a.m. to 5:30 p.m. each day. The exhibit uses virtual reality technology to simulate the potentially deadly consequences of using a phone while driving. The exhibit also features a memorial wall, a wall of keys representing lives lost and a wall made to look like crushed car parts. The Liberty Science Center is located at 222 Jersey City Boulevard.

Representatives of Congress and the National Space Council joined President Donald J. Trump, Apollo astronaut Jack Schmitt and current NASA astronaut Peggy Whitson Monday, Dec. 11, 2017, for the president’s signing of Space Policy Directive 1, a change in national space policy that provides for a U.S.-led, integrated program with private sector partners for a human return to the Moon, followed by missions to Mars and beyond.
Lunar Sample 70215 was retrieved from the Moon’s surface and returned by NASA’s Apollo 17 crew. The sample is a basaltic lava rock similar to lava found in Hawaii. It crystallized 3.84 billion years ago when lava flowed from the Camelot Crater. Sliced off a parent rock that originally weighed 8,110 grams, the sample weighs 14 grams, and is very fine grained, dense and tough.

Some science journals that claim to peer review papers do not do so
Posted by Derick Lee in categories: business, economics, science
Behind all this is a change in the way a lot of journals make their money. Over the past decade, many have stopped selling subscriptions. Instead, they charge authors a publication fee and permit people to read the result for nothing. This “open access” business model has the advantage of increasing the dissemination of knowledge, but it also risks corrupting the knowledge thus disseminated.
WHETHER to get a promotion or merely a foot in the door, academics have long known that they must publish papers, typically the more the better. Tallying scholarly publications to evaluate their authors has been common since the invention of scientific journals in the 17th century. So, too, has the practice of journal editors asking independent, usually anonymous, experts to scrutinise manuscripts and reject those deemed flawed—a quality-control process now known as peer review. Of late, however, this habit of according importance to papers labelled as “peer reviewed” has become something of a gamble. A rising number of journals that claim to review submissions in this way do not bother to do so. Not coincidentally, this seems to be leading some academics to inflate their publication lists with papers that might not pass such scrutiny.
Experts debate how many journals falsely claim to engage in peer review. Cabells, an analytics firm in Texas, has compiled a blacklist of those which it believes are guilty. According to Kathleen Berryman, who is in charge of this list, the firm employs 65 criteria to determine whether a journal should go on it—though she is reluctant to go into details. Cabells’ list now totals around 8,700 journals, up from a bit over 4,000 a year ago. Another list, which grew to around 12,000 journals, was compiled until recently by Jeffrey Beall, a librarian at the University of Colorado. Using Mr Beall’s list, Bo-Christer Björk, an information scientist at the Hanken School of Economics, in Helsinki, estimates that the number of articles published in questionable journals has ballooned from about 53,000 a year in 2010 to more than 400,000 today. He estimates that 6% of academic papers by researchers in America appear in such journals.
