Blinged-Out Fat Blob Nanotrucks for Targeted Drug Delivery

by Sharon Neufeldt in I Can Has Science?

Targeted drug delivery is a popular area of research that melds together the disciplines of chemistry, medicine, and materials. The basic idea is to develop ways to give a person a and somehow get that medicine to go to exactly … Continue reading →... Read more »

For infants, walking is more than just another step in motor development

by BPS Research Digest in BPS Research Digest

When an infant starts walking, this important achievement is more than just a milestone in motor control. According to Melissa Clearfield, the child's newfound locomotor skill arrives hand-in-hand with a raft of other changes in social behaviour and maturity. This is an unfolding, interactive process of development that before now has been little explored by psychologists.

Clearfield first had 17 non-walking infants (aged between 9 and 11 months) twice spend ten minutes exploring a 3m by 3m fl........ Read more »

Brain Measures Predict Future Improvement in Children With Dyslexia

by Livia in Reading and Word Recognition Research

Accessibility: Intermediate

Disclaimer: My PI is an author on this paper.

There is a lot of variability in outcomes for children diagnosed with dyslexia. Some children improve greatly over time, while others don't. Today, we're looking at a paper that asks whether it's possible to predict improvement in children with dyslexia.

Fumiko Hoeft and colleagues scanned children with and without dyslexia while performing a word rhyme task. They also tested the children on several reading measures......... Read more »

Utricularia sucks: Aquatic carnivorous plants that evolved vacuum traps

by Ryan Kitko in Cunabulum

Utricularia, commonly known as the bladderworts, is a genus of approximately 230 species of carnivorous plants that have evolved an amazing suction trap to supplement their nutrient requirements by trapping and digesting convenient little arthropoid or crustacean packets of nitrogen, phosphorous, and other essential chemicals. Not all species are aquatic, as this cosmopolitan genus has also evolved species with lithophytic (growing in or on rocks), epiphytic, and terrestrial habits.The rootless ........ Read more »

Telomerase can reverse the aging process... sort of

by Charles Daney in Science and Reason

Biologists are, at long last, beginning to understand the molecular processes responsible for aging in complex (multicellular) organisms – and to investigate ways to counteract these processes. We discussed one line of research in this recent article about a particular sirtuin (SIRT3) that helps relieve oxidative stress that can lead to DNA damage, which generally leads, in turn, to cell senescence or death.While oxidative stress is certainly a significant factor in aging, possibly the mos........

Classics: Tragedy of the Commons

by CJA Bradshaw in ConservationBytes

Another one from our upcoming chapter in the book ‘Biodiversity’ to be published later this year by InTech. – Although not a conservation biology paper per se, Hardin’s classic essay (Hardin, 1968) changed the way we think about managing natural resources that lack definitive ownership. The thesis of the “tragedy of the commons” is that [...]... Read more »

Got beef with worms?

by zacharoo in Lawn Chair Anthropology

Photo: {http://news.brown.edu/pressreleases/2009/09/bilateral}, by Eric Rottinger at kahikai.orgFlipping through the current issue of Current Biology, it sounds like someone has some serious beef with acoelomorph flatworms. Apparently these critters have been used as a model for the 'missing link' between simple-bodied cnidarians (like jellyfish) and bilaterians (bilaterally symmetrical animals like you and me and flies and fish, and really a good deal of animal biodiversity); and this may be pr........

Deprived, Deranged and Disrupted

by perishedcore in Changing Heart and Mind

Research about sleep inevitably leads to circadian rhythms and CLOCK genes. One group of researchers goes farther and suggests that 24 hour exposure to light beyond that produced by the denizens of space and the moon and demands which interfere or replace traditional sleep wake cycles may be doing damage beyond imagination. Circadian (daily) rhythms [...]... Read more »

Genomic Imprinting VI: Hemimethylation

by Jon Wilkins in Lost in Transcription

So, last time, we discussed the fact that the expression differences associated with genomic imprinting rely on the existence of epigenetic differences, such as DNA methylation. We also mentioned that those differences are established separately in the male and female germ lines. That is, one methylation pattern is established in the female germ line during oogenesis (egg formation), while a different pattern is established in the male germ line during spermatogenesis (sperm formation).

It is s........ Read more »

Lunar cycles and reproduction in the deep sea

by Uncharted Atolls in Uncharted Atolls

Some biological patterns in marine species, particularly concerning reproduction, are related to the moon.  Shallow-ocean corals, for example, undergo mass spawning events (the synchronous release of eggs and sperm into the water column to combine), the timing of which, are set to the lunar clock.  Reef fishes, shallow-ocean echinoderms, mollusks and more, also time spawning [...]...
