Explicit instruction makes children less likely to engage in spontaneous exploration and discovery

Suppose someone showed you a novel gadget and told you, "Here's how it works," while demonstrating a single function, such as pushing a button. What would you do when they handed it to you?

Novel cerebrospinal fluid proteins found in greater concentrations in Alzheimer's patients

Researchers at the Sahlgrenska Academy, University of Gothenburg, have identified a series of novel proteins in human cerebrospinal fluid. The proteins, which carry specific sugar molecules, are found in greater concentrations in patients with dementia caused by Alzheimer's disease than in patients with dementia caused by other diseases. This gives hope for new forms of treatment in the future.

Autism Speaks Weatherstone fellows publish new mouse model findings in Cell journal

Autism Speaks Weatherstone Pre-Doctoral Fellows M. Ali Bangash, a 2009 fellow, and Mehreen Kouser, a 2010 fellow, recently published new findings in the journal Cell that shed light on the biology of autism.

Potential new treatment for rare, inherited metabolic disease

The rare disorder alpha-mannosidosis can cause serious damage to the nervous system and other organ systems. In Tromsø, Norway, researchers have been studying the disease for 20 years - and a treatment may soon be available.

Amylin behaves when guarded by zinc

In type 2 diabetes, a protein called amylin forms dense clumps that shut down insulin-producing cells, wreaking havoc on the control of blood sugar. But zinc has a knack for preventing amylin from misbehaving.

Resveratrol may prevent negative effects of spaceflight and sedentary lifestyles

As strange as it sounds, a new research study published in the FASEB Journal (http://www.fasebj.org), suggests that the "healthy" ingredient in red wine, resveratrol, may prevent the negative effects that spaceflight and sedentary lifestyles have on people.

New book explores extraordinary progress against cancer

A new book looking at the extraordinary progress being made to fight cancer titled Why Millions Survive Cancer has been written by Dr Lauren Pecorino, Principal Lecturer in Cancer Biology at the University of Greenwich.

Study identifies key virus-sensing mechanism necessary for successful immune response against HIV

Although our body's defense mechanisms are usually capable of detecting and destroying many types of pathogens, some viruses are able to evade the immune system and make us sick. In particular, "retroviruses," such as human immunodeficiency virus (HIV), are notorious for eluding host immune defenses and causing disease.

Men better than women at visuo-spatial and auditory-spatial tasks

Differences in male and female behaviour are often subject to study. Women are known to be more verbally fluent, have better manual dexterity and are better at noticing things (like a new haircut). Men on the other hand often take less time parking their cars and have less trouble than women in navigating in a new city.

New book explores research into viral nanoparticles

Viruses that attack plants, insects, mammals and bacteria are proving effective platforms for delivering medicines and imaging chemicals to specific cells in the body, as building blocks for tiny battery electrodes and computer data storage devices, and other nanotechnologies.

Two defective genes may cause telomere elongations in cancer cells: Study

Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten.

Genetic mutations in abnormal bone marrow can predict mortality of MDS patients

For patients with myelodysplastic syndromes (MDS), choosing the appropriate treatment depends heavily on the prognosis. Those patients at the highest risk of dying from their disease are typically offered the most aggressive therapies, while patients at lower risk could live several years with MDS, needing only supportive care or other relatively side-effect free treatments.

Scientists discover enzyme that can regulate breast cancer development

Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off.

Research sheds light on well-documented 'other-race effect'

Northwestern University researchers have provided new biological evidence suggesting that the brain works differently when memorizing the face of a person from one's own race than when memorizing a face from another race.

New analytical approach can organize large amounts of varied cancer genetic data

The technology that allows scientists to profile the entire genome of individual tumors offers new hope for discovering ways to select the best treatment for each patient's particular type of cancer. However, these profiles produce huge amounts of data, and the volume alone creates unique analytical problems.

Erratic investment responses can make a smart portfolio richer

Playing the stock market can be a risky game. And when the market behaves unpredictably, public fear can lead to erratic investment responses and market chaos.

Epigenetics affects whether or not stem cells differentiate

Adult stem cells and progenitor cells may not come with a clean genetic slate after all. That's because a new report in the FASEB Journal shows that adult stem or progenitor cells have their own unique "epigenetic signatures," which change once a cell differentiates. This is important because epigenetic changes do not affect the actual make up in a cell's DNA, but rather, how that DNA functions.

Study reveals unique pattern of brain activity when false memories are formed

How easy is it to falsify memory? New research at the Weizmann Institute shows that a bit of social pressure may be all that is needed. The study, which appears Friday in Science, reveals a unique pattern of brain activity when false memories are formed - one that hints at a surprising connection between our social selves and memory.

Researchers identify altered expression of endogenous retroviruses in BSE-infected macaques

Prion diseases such as Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy (BSE) in cattle are transmissible neurodegenerative diseases linked to the aggregation of the prion protein in the central nervous system.
