Why do we Need Dark Energy to Explain the Observable Universe?

Why do we need dark energy to explain the observable universe?

Against all reason, the universe is accelerating its expansion. When two prominent research teams dropped this bombshell in 1998, cosmologists had to revise their models of the universe to include an enormous and deeply mysterious placeholder they called “dark energy.” For dark energy to explain the accelerating expansion, it had to constitute more than 70 percent of the universe. It joined another placeholder, “dark matter,” constituting 20 percent, in overshadowing the meager 4 percent that make up everything else—things like stars, planets, and people.

An accelerating wave of expansion following the Big Bang could push what later became matter out across the universe, spreading galaxies farther apart the more distant they got from the wave’s center. If this did happen, it would account for the fact that supernovae were dim- they were in fact shoved far away at the very beginning of the universe. But this would’ve been an isolated event, not a constant accelerating force. Their explanation of the 1998 observations does away with the need for dark energy.

And Smoller and Temple say that once they have worked out a further version of their solutions, they should have a testable prediction that they can use to see if the theory fits observations.

Another interesting example of the scientific inquiry process at work in cosmology.

Shouldn’t the National Academy of Science (NAS), a congressionally chartered institution, promote open science instead of erecting pay walls to block papers from open access? The paper (by 2 public school professors) is not freely available online. It seems like it will be available 6 months after publication (which is good) but shouldn’t the NAS do better? Delayed open access, for organizations with a focus other than promoting science (journal companies etc.), is acceptable at the current time, but the NAS should do better to promote science, I think.

Merck and Elsevier Publish Phony Peer-Review Journal

Elsevier is one of those publishers fighting open science. They try to claim that the government publishing government funded research in an open way will tarnish science. The argument makes no sense to me. Here is another crazy action on their part: they published a “journal” funded by Merck to promote Merck products. Merck Makes Phony Peer-Review Journal:

Merck cooked up a phony, but real sounding, peer reviewed journal and published favorably looking data for its products in them. Merck paid Elsevier to publish such a tome, which neither appears in MEDLINE or has a website, according to The Scientist.

What’s sad is that I’m sure many a primary care physician was given literature from Merck that said, “As published in Australasian Journal of Bone and Joint Medicine, Fosamax outperforms all other medications….” Said doctor, or even the average researcher wouldn’t know that the journal is bogus. In fact, knowing that the journal is published by Elsevier gives it credibility!

As I have said the journals fighting open science should have their credibility questioned. They are putting their outdated business model above science. We should not see organizations that are focused on closing science research through deceptive publicity efforts and lobbying efforts as credible.

MIT Faculty Open Access to Their Scholarly Articles

MIT faculty open access to their scholarly articles

In a move aimed at broadening access to MIT’s research and scholarship, faculty at the Massachusetts Institute of Technology have voted to make their scholarly articles available to the public for free and open access on the Web.

The new policy, which was approved unanimously at an MIT faculty meeting on Wednesday, March 18 and took immediate effect, emphasizes MIT’s commitment to disseminating the fruits of its research and scholarship as widely as possible.

Under the new policy, faculty authors give MIT nonexclusive permission to disseminate their journal articles for open access through DSpace, an open-source software platform developed by the MIT Libraries and Hewlett Packard and launched in 2002. The policy gives MIT and its faculty the right to use and share the articles for any purpose other than to make a profit. Authors may opt out on a paper-by-paper basis.

MIT’s policy is the first faculty-driven, university-wide initiative of its kind in the United States. While Harvard and Stanford universities have implemented open access mandates at some of their schools, MIT is the first to fully implement the policy university-wide as a result of a faculty vote. MIT’s resolution is built on similar language adopted by the Harvard Faculty of Arts & Sciences in 2008.

It is good to see scientists putting advancing science above outdated journal business models. It is a bit of a shame that we have to be happy for such a small thing but given the state of those fighting against open science it is good to see those in favor of open access to science make progress.

Resurrection of the Human IRGM Gene

Interesting open access paper on Death and Resurrection of the Human IRGM Gene. Author summary:

The IRG gene family plays an important role in defense against intracellular bacteria, and genome-wide association studies have implicated structural variants of the single-copy human IRGM locus as a risk factor for Crohn’s disease. We reconstruct the evolutionary history of this region among primates and show that the ancestral tandem gene family contracted to a single pseudogene within the ancestral lineage of apes and monkeys.

Phylogenetic analyses support a model where the gene has been “dead” for at least 25 million years of human primate evolution but whose ORF became restored in all human and great ape lineages. We suggest that the rebirth or restoration of the gene coincided with the insertion of an endogenous retrovirus, which now serves as the functional promoter driving human gene expression. We suggest that either the gene is not functional in humans or this represents one of the first documented examples of gene death and rebirth.

Open Science: Explaining Spontaneous Knotting

Shedding light on why long strands tend to become knotted

Anyone who has ever put up Christmas lights knows the problem: Holiday strands so carefully packed away last year are now more knotty than nice. In fact, they have become an inextricable, inexplicable, seemingly inevitable mess. It happens every year, like some sort of universal law of physics.

Which, it turns out, it basically is. In October, two UCSD researchers published the first physical explanation of why knots seem to form magically, not just in strands of Christmas lights, but in pretty much anything stringy, from garden hoses to iPod earbud cords to DNA.

“We’re not mathematicians,” Smith said. “We’re physicists. Physicists do experiments.”

UCSD researchers constructed a knot probability machine that involved placing a single length of string in a plastic box, sealing it, then rotating the box at a set speed for a brief period of time.

The experiment involved placing a single length of floppy string into a plastic box, sealing it, then rotating the box at a set speed for a brief time. The researchers did this 3,415 times, sometimes changing variables such as box size and string length.

Open access research paper: Spontaneous knotting of an agitated string by Dorian M. Raymer and Douglas E. Smith.

Above a critical string length, the probability P of knotting at first increased sharply with length but then saturated below 100%. This behavior differs from that of mathematical self-avoiding random walks, where P has been proven to approach 100%. Finite agitation time and jamming of the string due to its stiffness result in lower probability, but P approaches 100% with long, flexible strings.

As L [length] was increased from 0.46 to 1.5 m, P increased sharply. However, as L was increased from 1.5 to 6 m, P saturated at 50%.

Tripling the agitation time caused a substantial increase in P, indicating that the knotting is kinetically limited. Decreasing the rotation rate by 3-fold while keeping the same number of rotations caused little change in P.

We also did measurements with a stiffer string and observed a probability of finding a knot would approach 100% with an substantial drop in P.

Yet another interesting case of scientists explaining the world around us (and the value of open science).

John Conyers Against Open Science

Lawrence Lessig once again has written a good blog post: John Conyers and Open Access

Open access journals, such as, for example, those created by the Public Library of Science, have adopted a different publishing model, to guarantee that all all research is freely accessible online (under the freest Creative Commons license) immediately, to anyone around the world. This guarantee of access, however, is not purchased by any compromise in academic standards. There is still a peer-review process. There is still even a paper-based publication.

Pushed by scientists everywhere, the NIH and other government agencies were increasingly exploring this obviously better model for spreading knowledge. Proprietary publishers, however, didn’t like it. And so rather than competing in the traditional way, they’ve adopted the increasingly Washington way of competition — they’ve gone to Congress to get a law to ban the business model they don’t like. If H.R. 801 is passed, the government can’t even experiment with supporting publishing models that assure that the people who have paid for the research can actually access it. Instead, if Conyers has his way, we’ll pay for the research twice.

The insanity in this proposal is brilliantly described by Jamie Boyle in this piece in the FT. But after you read his peace, you’ll be even more puzzled by this. For what possible reason could Conyers have for supporting a bill that 33 Nobel Prize Winners, and the current and former heads of the NIH say will actually hurt scientific research in America? More pointedly, what possible reason would a man from a district that insists on the government “Buying American” have for supporting a bill that basically subsidizes foreign publishers (for the biggest players in this publishing market are non-American firms, making HR 801 a kind of “Foreign Publishers Protection Act”)?

the co-sponsors of this bill who sit on the Judiciary Committee received on average two-times the amount of money from publishing interests as those who haven’t co-sponsored the bill.

The damage done to science by dinosaurs fighting progress and corrupt or inept politicians is very disheartening. Thankfully we have been able to achieve great things in spite of politicians trying to favor their donors and harm the scientific community.

Study on Citation of Open Access Papers v. Closed Access Papers

Open Access to Scientific Papers May Not Guarantee Wide Dissemination

To test this theory, James A. Evans, an assistant professor of sociology at the University of Chicago, and Jacob Reimer, a student of neurobiology also at the University of Chicago, analyzed millions of articles available online, including those from open source publications and those that required payment to access.

The results were surprising. On average, when a given publication was made available online after being in print for a year, being published in an open source format increased the use of that article by about 8 percent. When articles are made available online in a commercial format a year after publication, however, usage increases by about 12 percent.

“Across the scientific community,” Evans said in an interview, “it turns out that open access does have a positive impact on the attention that’s given to the journal articles, but it’s a small impact.”

Yet Evans and Reimer’s research also points to one very positive impact of the open source movement that is sometimes overlooked in the debate about scholarly publications. Researchers in the developing world, where research funding and libraries are not as robust as they are in wealthier countries, were far more likely to read and cite open source articles.

The University of Chicago team concludes that outside the developed world, the open source movement “widens the global circle of those who can participate in science and benefit from it.”

So while some scientists and scholars may chose to pay for scientific publications even when free publications are available, their colleagues in other parts of the world may find that going with open source works is the only choice they have.

I remain a strong advocate for open science. The out of date model of publishing research in closed journals does not make sense. Especially not for any government funded research or any research supported by foundations, universities or others that aim to promote science.

The quote above and the interview webcast also provide unclear data on what the actual impact is (on how often a paper is cited in other papers). Maybe the article would be clearer but I can’t tell because it is closed access. This link has some worthwhile comments: Generalizing the OA impact advantage.

Canada Film Board Provides Open Access

The National Film Board of Canada is marking its 70th anniversary in 2009 with a gift to Canadians and Web users: a new online Screening Room providing free home viewing of over 700 productions, films, trailers and clips from the NFB’s world-renowned collection.

“This new online Screening Room is the latest example of how the NFB plays a major role in the free exchange of ideas through cinema,” said Tom Perlmutter, Government Film Commissioner and Chairperson of the National Film Board of Canada. “At a time when issues are inter-connected and global communications are mobile and instantaneous, Canada needs a voice. More than ever, the NFB provides that voice: empowering Canadians to share their concerns, express their points of view, tell Canada’s stories. The world is changing – our stories continue.”

From historical films dating back to 1928 to current contemporary releases, including award-winning documentaries, animation and fiction, this initiative invites Canadians from all regions, to browse, discover and be entertained by the stories that bind us together.

The NFB has also opened its vaults to bring forgotten gems to light: archival works that offer rare glimpses back into our past, from Canada’s sacrifices during World War II to traditional communities, exploring the changing face of Canada over the decades.

The site includes many science and nature films including: Life on IceKluane National ParkIn Search of the Bowhead WhaleThe Enduring Wilderness (Canada’s Natural Parks)

The National Film Board of Canada showing far more vision than many others clinging to outdated models. The internet provides a great opportunity for sharing and using open access to share ideas.

Dolphins Using Tools to Hunt

Cool open access research from PLoS One, Why Do Dolphins Carry Sponges?

Tool use is rare in wild animals, but of widespread interest because of its relationship to animal cognition, social learning and culture. Despite such attention, quantifying the costs and benefits of tool use has been difficult, largely because if tool use occurs, all population members typically exhibit the behavior. In Shark Bay, Australia, only a subset of the bottlenose dolphin population uses marine sponges as tools, providing an opportunity to assess both proximate and ultimate costs and benefits and document patterns of transmission.

We compared sponge-carrying (sponger) females to non-sponge-carrying (non-sponger) females and show that spongers were more solitary, spent more time in deep water channel habitats, dived for longer durations, and devoted more time to foraging than non-spongers; and, even with these potential proximate costs, calving success of sponger females was not significantly different from non-spongers. We also show a clear female-bias in the ontogeny of sponging. With a solitary lifestyle, specialization, and high foraging demands, spongers used tools more than any non-human animal. We suggest that the ecological, social, and developmental mechanisms involved likely (1) help explain the high intrapopulation variation in female behaviour, (2) indicate tradeoffs (e.g., time allocation) between ecological and social factors and, (3) constrain the spread of this innovation to primarily vertical transmission.

The dolphins use the sponge to push along the ocean floor and disturb fish, that are hidden. Once the fish start swimming away the dolphin abandons the sponge and catches and eats the fish. Then the dolphin goes back and gets the sponge and continues.

HHMI on Science 2.0: Information Revolution

The Howard Hughes Medical Institute does great things for science and for open science. They have an excellent article in their HHMI Bulletin – Science 2.0: You Say You Want a Revolution?

Cross-pollination among research disciplines is in fact at the core of many other popular science blogs. Michael Eisen, an HHMI investigator at the University of California, Berkeley, is an avid blog reader who particularly enjoys John Hawks’ site on paleoanthropology, genetics, and evolution. A recent post there discussed a new sequencing of Neanderthal mitochondrial DNA. “It’s like a conduit into another whole world,” says Eisen.

The current extreme of collaboration via Science 2.0 is OpenWetWare.org. Begun in 2003 by Austin Che, who was then a computer science and biology graduate student at MIT, this biological-engineering Website uses the wiki model to showcase protocols and lab books: everything is open and can be edited by any of its 4,000 members.

“Most publishers wish open access would go away,” says Brown. It won’t. Major research-funding organizations, including NIH, HHMI, and the Wellcome Trust, now require their grantees to post their findings on openaccess Websites such as PLoS or PubMed Central within 12 months of publication in traditional journals. Publishers are pushing back, however, and in September, the House Judiciary Committee began holding hearings on whether the federal government should be allowed to require grantees to submit accepted papers to a free archive.

Toward a More Open Scientific Culture

Michael Nielsen wrote a great post, The Future of Science, which is also the topic of a book he is writing. He discusses how scientific advancement has often been delayed as those making discoveries did not share them openly. And how 300 years ago scientific journals and reward systems created ways for scientists to be rewarded for publication. And he continues with the need for the process to again change and promote more open sharing of scientific knowledge, which I agree with and have written about previously: Publishers Continue to Fight Open Access to Science, Science Journal Publishers Stay Stupid, The Future of Scholarly Publication, etc..

Why were Hooke, Newton, and their contemporaries so secretive? In fact, up until this time discoveries were routinely kept secret.

This cultural transition was just beginning in the time of Hooke and Newton, but a little over a century later the great physicist Michael Faraday could advise a younger colleague to “Work. Finish. Publish.” The culture of science had changed so that a discovery not published in a scientific journal was not truly complete. Today, when a scientist applies for a job, the most important part of the application is their published scientific papers.

This has been a great advance. Now we need to continue that advance to use the internet to make that publication open and increase the advantage of shared knowledge to society.

The adoption of the journal system was achieved by subsidizing scientists who published their discoveries in journals. This same subsidy now inhibits the adoption of more effective technologies, because it continues to incentivize scientists to share their work in conventional journals, and not in more modern media.

This means: making many more types of content available than just scientific papers; allowing creative reuse and modification of existing work through more open licensing and community norms; making all information not just human readable but also machine readable; providing open APIs to enable the building of additional services on top of the scientific literature, and possibly even multiple layers of increasingly powerful services. Such extreme openness is the ultimate expression of the idea that others may build upon and extend the work of individual scientists in ways they themselves would never have conceived.

To create an open scientific culture that embraces new online tools, two challenging tasks must be achieved: (1) build superb online tools; and (2) cause the cultural changes necessary for those tools to be accepted.

I agree we need to take advantage of the new possibilities to advance the practice of science. His full post is well worth reading.

Best Research University Rankings – 2008

The annual ranking of research Universities are available from Shanghai’s Jiao Tong University. The methodology values publications and faculty awards which provides a better ranking of research (rather than teaching). Results from the 2008 rankings of Top 500 Universities worldwide, country representation of the top schools:

location Top 100 % of World
Population
% of World GDP % of top 500
USA 54     4.6%   27.2%  31.6%
United Kingdom 11  0.9  4.9 8.3
Germany   6  1.3  6.0 8.0
Japan   4  2.0  9.0 6.2
Canada   4  0.5  2.6 4.2
Sweden   4  0.1  0.8 2.2
France   3  0.8  4.6 4.6
Switzerland   3  0.1  0.8 1.6
Australia   3  0.3  1.6 3.0
Netherlands   2  0.2  1.4 2.4
Denmark   2  0.1  0.6 0.8
Finland   1  0.1  0.4 1.2
Norway   1  0.1  0.7 0.8
Israel   1  0.1  0.3 1.2
Russia   1  2.2  2.0 0.4
China  20.5  6.6 6.0
India  17.0  1.9 0.4

There is little change in most of the data from last year, which I think is a good sign, it wouldn’t make much sense to have radical shifts over a year in these rankings. Japan lost 2 schools in the top 100, France lost 1. Denmark (Aarhus University) and Australia (University of Sydney) gained 1. Last year there was a tie so there were 101 schools in the top 100.

The most dramatic data I noticed is China’s number of top 500 schools went from 14 to 30, which made me a bit skeptical of what caused that quick change. Looking more closely last year they reported the China top 500 totals as (China 14, China-Taiwan 6 and China-Hong Kong 5). That still gives them an impressive gain of 5 schools.

Singapore has 1 in the 102-151 range. Taiwan has 1 ranked in the 152-200 range, as do Mexico, Korea and Brazil. China has 9 in the 201-302 range (including 3 in Hong Kong). India has 2 in the 303-401 range.

ASU Science Studio Podcasts

Science Studio offers podcasts by the Arizona State University School of Life Sciences with professors discussing science; it is another excellent source of science podcasts. Podcasts include:

  • Of Whales, Fish and Men: Managing Marine Reserves – With 90% of the world’s fisheries in a state of collapse, the questions around establishing marine reserves, monitoring, and species/stock recovery take on critical dimensions. But how do decision-makers, stakeholders, and the public formulate effective conservation policies; ones right for their community?
  • Biology on Fire – Regents’ Professor, Mac Arthur Fellow, author and a world’s expert on fire and fire ecology Stephen Pyne talks about how fire, its use, misuse, and its biological nature have shaped our world, before and because of man, and learn how policies of the past still reverberate in our present, in Arizona and globally.
  • Giant Insects: Not just in B movies – Professor Jon Harrison sheds light on the evolution of his scientific career and nature’s biggest order: arthropods. How big is big? In the Paleozoic, cockroaches were the size of housecats and dragonflies the size of raptors.
  • Special Feature: Building a science career – One of the most highly cited ecologists in the world, Jane Lubchenco trod her own unique path to success. In this live recording with the Association for Women in Science, she explains how assertiveness, the art of negotiation, and knowing the currency for promotion and tenure can make the difference between achieving balance between family and career and dropping out the leaky academic pipeline that leads to advancement.

These podcasts are great way to use the internet to serve the mission of universities: to educate. And a great way to promote science.

Antarctic Fish “Hibernate” in Winter

Antarctic Fish “Hibernate” in Winter

This is the first time fish have been seen actively becoming torpid—a state similar to hibernation in land animals—as part of an annual cycle. “A lot of freshwater fish go [unexpectedly] dormant in winter because a drop in temperature lowers their metabolism,” said study co-author Hamish Campbell, a zoologist at the University of Queensland, Australia.

“By contrast, these Antarctic fish actively reduce their ‘cost of living,’” he said… “The fish became 20 times less active in winter compared to summer,”… About every week or so the cod wake up and swim around for a few hours, the team observed. “This is quite similar to ‘denning’ in bears, where the hibernation isn’t so deep and the animals can be disturbed, then spend some time awake before going back to bed,” Fraser said.
