Nanotechnology enables a major manufacturing paradigm shift
Much has been said about the great impact and improvements nanotechnology will make in our lives–offering cost-effective green energy, medical treatment and therapy breakthroughs, and new advanced nanoelectronics that are small and ubiquitous, even becoming a part of our future wardrobe.
New Crops Needed For New Climate
Plants grown under high carbon dioxide and drought conditions show an increase in toxic compounds, a decrease in protein content and a decrease in yield. Therefore new cultivars should be developed in order to sustain food production in a future environment.
Music May Have A Future Role In Heart And Stroke Patient Rehabilitation
Researchers find evidence that music can synchronize with and influence the cardiovascular system. Crescendos in music narrowed blood vessels on the skin, and increased blood pressure and heart rate. Results explain how music can influence the cardiovascular system, and provide a rationale for using music as therapeutic tool for blood pressure, rehabilitation and more.
New Exotic Subatomic Particle Observed: Omega-sub-b Baryon
Physicists have announced the observation of a new particle, the Omega-sub-b (Ω
b). The particle contains three quarks -- two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton's mass.
Magic Ingredient In Breast Milk Protects Babies' Intestines
Scientists have discovered that an ingredient in human breast milk protects and repairs the delicate intestines of newborn babies. The ingredient called pancreatic secretory trypsin inhibitor, or PSTI, is found at its highest levels in colostrum -- the milk produced in the first few days after birth. The new study highlights the importance of breastfeeding in the first few days after the birth.
Study Advises Chinese Government To Change Fuel In Millions Of Households
Scientists in China are recommending that the Chinese government consider phasing out the direct burning of traditional chunks of coal in millions of households. It suggests that the government substitute coal briquettes and improved stoves for cooking and heating to help reduce the country's high air pollution levels.
'Sleep Walking' And Talking That Can Occur With Popular Sleep-aid Ambien Explained
Some people who take the fast-acting sleep-aid zolpidem (Ambien) have been observed walking, eating, talking on the phone and even driving while not fully awake. Many often don't remember doing any of these activities the next morning. Similarly, this drug has been shown to awaken the minimally conscious into a conscious state. A new study may help explain why these "awakenings" occur.
New Take On Growth Factor Signaling In Tamoxifen Resistance
Differences in growth factor (GF) signaling may cause the poor prognosis in some breast cancer cases. A new study suggests that some estrogen receptor-positive breast cancers respond poorly to tamoxifen because of increased GF signaling.
New Lasers Drive Powerful Applications
Telecoms, healthcare and display technology will be the major beneficiaries of a new generation of semiconductor lasers developed in a massive research effort. Better cancer treatment, wider bandwidth and smaller, better displays could be on their way.
What Is The Risk Of Obesity While Taking Antidepressant Drugs?
Major depressive episode (MDE) does not appear to increase the risk of obesity. The cross-sectional associations that have been reported in this study, albeit inconsistently, in the literature probably represent an effect of obesity on MDE risk. Pharmacologic treatment with antidepressants may be associated with an increased risk of obesity, and strategies to offset this risk may be useful in clinical practice.
Study Of Flower Color Shows Evolution In Action
Scientists at UC Santa Barbara have zeroed in on the genes responsible for changing flower color, an area of research that began with Gregor Mendel's studies of the garden pea in the 1850's.
Natural-born Divers And The Molecular Traces Of Evolution
When the ancestors of present marine mammals returned to the oceans, their physiology had to adapt radically. Scientists have been studying how myoglobin, the molecule responsible for delivering oxygen to the muscles during locomotion, has been modified in seals and whales to help them cope with the needs of a life at sea.
Enzyme Doesn't Act Alone In Atrial Fibrillation
An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. However, it doesn't act alone, say researchers.
