Evaluation of a spatial ecosystem model: predictions and data

by sceintists from the Marine group at CEES in Marine Science blog




Spatial Ecosystem models can be useful but need to be validated with data. Our study validates for the first time the spatial version of the commonly used Ecopath with Ecosim ecosystem modelling suite. We find that spatial distribution of fish species is well predicted by the model, but fishing effort distribution is not.

Clinical trials for rare diseases – finding and keeping patients

by Danielle Stevenson in BHD Research Blog

International Clinical Trial day (May 20th) celebrates the medical advances as a result of clinical trials. Clinical trials are essential to ensure drug safety and efficacy, and the recent increase in the development of orphan drugs has led to an increase in rare disease clinical trials. The nature of rare diseases creates specific challenges for clinical trial design and patient recruitment.... Read more »

Early Start Denver Model (ESDM) and autism: 2 year outcomes

by Paul Whiteley in Questioning Answers

"These results provide evidence that gains from early intensive intervention are maintained 2 years later. Notably, core autism symptoms improved in the ESDM [Early Start Denver Model] group over the follow-up period relative to the COM [community-intervention-as-usual] group."Those were some of the conclusions reported in amongst the potentially very important results from Annette Estes and colleagues [1] looking at "the sustained effects of early intervention" followin........

E-cigarettes don’t help smokers stop smoking (or smoke less)

by Megan Cartwright in Science-Based Writing

Electronic cigarettes don’t help people quit smoking or even smoke less. This conclusion – which further squashes hopes that e-cigarettes might enable America’s 42 million smokers to quit – comes from one of the largest studies of e-cigarette users to … Continue reading →... Read more »

You can make people less religious by flicking their brain with magnetic pulses

by Tom Rees in Epiphenom

Many years ago, a guy called Michael Persinger achieved a certain amount of fame with a claim that stimulating the right part of the brain with a magnetic field could give people a religious experience. Although others weren’t able to get the same results, studies since then have found that brain damage to parts of [Read More...]... Read more »

Respiratory illness and schizophrenia

by Paul Whiteley in Questioning Answers

"Schizophrenia is associated with impaired lung function and increased risk for pneumonia, COPD [Chronic obstructive pulmonary disease] and chronic bronchitis."That was the primary conclusion reached in the paper by Krista Partti and colleagues [1] who aimed to "compare the respiratory health of people with psychosis with that of the general population." Their findings, based on data from "a nationally representative sample of 8028 adult Finns" (Finns as in inhabitants of Finland) invo........ Read more »

Tiny grains of lithium dramatically improve performance of fusion plasma

by Dr. Jekyll in Lunatic Laboratories

While fusion might still be a far off dream, a new discovery may help bring that dream closer to reality. Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that could quicken the development of large scale fusion energy. The scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically....

battling superbugs the evolutionary way

by Greg Fish in weird things

We’re using far too many antibiotics. That has been the cry from the FDA and the WHO for the last several years as more and more antibiotic-resistant strains have been found after they had colonized or killed patients. Of course these bacteria aren’t completely immune to our arsenals of drugs, they’re just harder to kill with certain antibiotics or require different ones, but a rather small, yet unsettling number, have required doctors to use every last antibacterial weapon [...] ......

Why Some Bugs Are Attracted to the Wrong Species

by Elizabeth Preston in Inkfish



The squash bug mating orgies that biologist Christine Miller began noticing in gardens around Gainesville were nothing unusual. Dozens of insects were crowded together, the petite males along with the bulkier females, to search for partners. The unusual thing was that some males were copulating with females of the wrong species—apparently, they found them irresistible.

When Jen Hamel arrived at Miller's University of Florida lab to do her postdoctoral research, she took up the mystery o........ Read more »

Video Tip of the Week: NCBI Tree Viewer

The helpful folks at NCBI have been ramping up their outreach. I’ve been watching a lot of their webinars, and they are trying different styles. The more traditional ones that are about the length of a seminar, and lately shorter quick-hit types of things. Both of them are valuable. Some topics need a good foundational […]... Read more »

Pets: Building Community One Friend at a Time

by CAPB in Companion Animal Psychology Blog

Even indoor pets help us get to know other people, according to new research in four cities in the US and Australia.It’s easy to see how people who regularly walk their dog can get to know others. They might strike up friendly conversations about dogs, or learn to avoid certain people because of the way their off-leash dog charges up with unwanted “friendly” advances. It’s less obvious for people who don’t walk their dogs, or who have pets that are always indoors. But a new study by re........ Read more »

What Can "Lived Experience" Teach Neuroscientists?

by Neuroskeptic in Neuroskeptic_Discover

A provocative paper says that neuroscientists who research mental health problems ought to listen to the views of people who have experienced those conditions.

The piece, from Australian authors Anthony Stratford and colleagues, is published in The Psychiatric Quarterly.



Here are some highlights:
Traditionally, mental health consumer [i.e. patient] involvement in research activities has largely been as "subjects"... the passive recipients of research activity... This approach does lit... Read more »

The Ugly Butterfly Gets The Girl

by Mark Lasbury in As Many Exceptions As Rules

A current theory is that humans (and other animals) perceive symmetry as beauty and is desirable in a mate. Symmetric bodies and faces are correlated with strength, overall health, facial beauty, and dancing ability, but also with extramarital affairs. On the other hand, on butterfly thrives on ugliness. Asymmetric wings actually help males fly better during sexual competitions and gives them a reproductive advantage.... Read more »

Narcissists and Pronouns: “I”, “me”, “mine” 

by Doug Keene in The Jury Room

Conservative commentators like to say Barack Obama is cold and aloof (and narcissistic) because he uses so many personal pronouns in speeches. However, when compared to past Presidents, Obama’s personal pronoun use is actually lower than any President since 1945. It’s an interesting example of how our preexisting beliefs (and political orientation) skew how we […]

Severe obesity pre-pregnancy and offspring developmental outcome

"Children whose mothers were severely obese before pregnancy had increased risk for adverse developmental outcomes."That was the conclusion reached in the paper by Heejoo Jo and colleagues [1] based on results derived from the Infant Feeding Practices Study II (IFPS II) "a US nationally distributed longitudinal study of maternal health and infant health and feeding practices."
