Being bilingual may help autistic children

Science Daily (US) - 16/01/2018
Children with Autism Spectrum Disorders (ASD) often have a hard time switching gears from one task to another. But being bilingual may actually make it a bit easier for them to do so, according to a new study.

Youth using alternative tobacco products are more likely to smoke one year later

Science Daily (US) - 15/01/2018
Nonsmoking adolescents who use e-cigarettes, smokeless tobacco or tobacco water pipes are more likely to start smoking conventional cigarettes within a year, according to new research.

Key player in cell metabolism identified

Science Daily (US) - 15/01/2018
Researchers have identified a key role for EXD2 in protein production in the mitochondria, the cellular organelles responsible for the majority of energy generation.

Biomaterials with 'logic gates' release therapeutics in response to environmental triggers

Science Daily (US) - 15/01/2018
Scientists have announced that they have built and tested a new biomaterial-based delivery system -- known as a hydrogel -- that will encase a desired cargo and dissolve to release its freight only when specific physiological conditions are met.

Remote-controlled cancer immunotherapy system

Science Daily (US) - 15/01/2018
A team of researchers has developed an ultrasound-based system that can non-invasively and remotely control genetic processes in live immune T cells so that they recognize and kill cancer cells.

Stop the clots, spare the coagulation

Science Daily (US) - 15/01/2018
In the fight to cure thromboinflammatory diseases, one of the target molecules is thrombin, a protein that promotes inflammation and can cause blood clots. However, inhibiting thrombin too much can lead to uncontrolled bleeding, limiting the use of anti-inflammatory drugs. Now, researchers have found that a class of small molecule called 'parmodulins' can reduce inflammation without compromising normal blood clotting, making parmodulins attractive candidates for new, safer drugs.

We will treat cancer by making it 'slim down'

Science Daily (US) - 15/01/2018
For years, attempts have been made to understand the mechanism behind the proliferation of cancer cells:  they need metabolites to grow and proliferate as much as a vehicle needs gasoline or electricity to move.  However, until now it was not known which metabolites cancer cells actually need. Medical researchers have now identified one of the mechanisms behind this process.

Fast-tracking T-cell therapies with immune-mimicking biomaterials

Science Daily (US) - 15/01/2018
Researchers have developed a material-based T-cell-expansion method using APC-mimetic biomaterial scaffolds, which helps achieve greater expansion of primary mouse and human T cells than existing methods.

Possible cause of early colonial-era Mexican epidemic identified

Science Daily (US) - 15/01/2018
Researchers have used new methods in ancient DNA research to identify Salmonella enterica Paratyphi C, a pathogen that causes enteric fever, in the skeletons of victims of the 1545-1550 cocoliztli epidemic in Mexico, identifying a possible cause of this devastating colonial epidemic.

Flipping the switch: Dietary fat, changes in fat metabolism may promote prostate cancer metastasis

Science Daily (US) - 15/01/2018
Researchers have shed new light on the genetic mechanisms that promote metastasis in the mouse model and also implicated the typical Western high-fat diet as a key environmental factor driving metastasis.

A matter of mobility: New strategy for drug discovery

Science Daily (US) - 15/01/2018
A joint industry/academia study of a cancer target protein reveals unusual relation between binding site flexibility and drug-target lifetime. The results suggest a new strategy for drug discovery.

Power stations in cells may protect brain against Parkinson´s

Science Daily (US) - 15/01/2018
A new study shows that impairment in mitochondria may actually protect the brain in Parkinson’s disease.

Surfers three times more likely to have antibiotic-resistant bacteria in guts

Science Daily (US) - 15/01/2018
Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.

Teens who were severely bullied as children at higher risk of suicidal thoughts, mental health issue

Science Daily (US) - 15/01/2018
Teens who were severely bullied as children by peers are at higher risk of mental health issues, including suicidal thoughts and behaviours, according to new research.

Flawed research methods exaggerate the prevalence of depression

Science Daily (US) - 15/01/2018
The common practice of using patient self-report screening questionnaires rather than diagnostic interviews conducted by researchers has resulted in overestimates of the prevalence of depression, according to a new analysis.

Genes that aid spinal cord healing in lamprey also present in humans, researchers discover

Science Daily (US) - 15/01/2018
Many of the genes involved in natural repair of the injured spinal cord of the lamprey are also active in the repair of the peripheral nervous system in mammals, according to a new study.

Energy drinks can negatively impact health of youth

Science Daily (US) - 15/01/2018
Over half of Canadian youth and young adults who have consumed energy drinks have experienced negative health effects as a result, according to a new study.

Genes that repair spinal cord in fish are also in humans, researchers find

Science Daily (US) - 15/01/2018
Many of the genes that repair an injured spinal cord in a fish called the lamprey are also active in the repair of the peripheral nervous system in mammals, researchers report.

Electronic modulation of carotid sinus nerve can be used as a treatment for type 2 diabetes in rats

Science Daily (US) - 15/01/2018
In a new study in rats, researchers have demonstrated that is possible to restore insulin sensitivity and glucose homeostasis by modulating electrically the carotid sinus nerve, the sensitive nerve that connects the carotid body with the brain.

Can early symptoms predict bipolar disorder? Evidence shows differing patterns of risk factors

Science Daily (US) - 13/01/2018
Two patterns of antecedent or 'prodromal' psychiatric symptoms may help to identify young persons at increased risk of developing bipolar disorder (BD), according to a new analysis.
