An express-lane for the Internet
- ScienceDaily
- 10/3/16 20:55
The Internet is expected to be inundated in the future with billions of gigabytes (or exabytes) of data as high-definition video and other bandwidth-busting downloads become the norm. The cost of upgrading the Internet for this so-called "exaflood" could make Web connections too expensive for most consumers. Internet service providers may be able to keep prices down by opening up an express-lane...
New hormone treatment shows potential to reverse infertility
- ScienceDaily
- 10/3/16 20:55
Twice weekly injections of the hormone kisspeptin may provide a new treatment to restore fertility in some women. The findings show that twice-weekly injections of kisspeptin can lead to increases in the levels of sex hormones, which control the menstrual cycle. This is the first study to show this effect can be maintained over the long term and it may lead to new therapies for women whose...
UV exposure has increased over the last 30 years, but stabilized since the mid-1990s
- ScienceDaily
- 10/3/16 20:55
NASA scientists analyzing 30 years of satellite data have found that the amount of ultraviolet radiation reaching Earth's surface has increased markedly over the last three decades. Most of the increase has occurred in the mid-and-high latitudes, and there's been little or no increase in tropical...
Keeping up with the neighbors speeds vaccine use
- ScienceDaily
- 10/3/16 20:55
Researchers have conducted an analysis of worldwide use of Haemophilus influenza Type b vaccine (Hib) to determine what factors influenced a nation's adoption of the vaccine. The study found that a nation's eligibility for support from the Global Alliance for Vaccine and Immunization and whether a country's neighbors used the vaccine were major influencing factors in addition to price of the...
Anti-obesity drugs unlikely to provide lasting benefit according to scientists
- ScienceDaily
- 10/3/16 05:00
Scientists argue that anti-obesity drugs fail to provide lasting benefits for health and well-being because they tackle the biological consequences of obesity, and not the important psychological causes of over-consumption and weight gain.
As girth grows, risk of sudden cardiac death shrinks
- ScienceDaily
- 10/3/16 05:00
Being skinny confers no advantage when it comes to the risk of dying suddenly from cardiac causes, new research suggests. Scientists found that non-obese heart failure patients -- including overweight, normal and underweight patients -- had a 76 percent increase in risk of sudden cardiac death compared to obese heart failure patients. Normal and underweight patients showed a startling 99 percent...
Blocking cancer in its path: New cellular defect discovered
- ScienceDaily
- 10/3/16 05:00
Researchers have discovered that a key cellular defect that disturbs the production of proteins in human cells can lead to cancer susceptibility. The scientists also found that a new generation of inhibitory drugs offers promise in correcting this defect.
Catastrophic flooding may be more predictable with new models
- ScienceDaily
- 10/3/16 05:00
Researchers have created a miniature river delta that replicates flooding patterns seen in natural rivers, resulting in a mathematical model capable of aiding in the prediction of the next catastrophic flood.
Depression: Antidepressants beneficial in physically ill patients
- ScienceDaily
- 10/3/16 05:00
Antidepressants are effective against depression in patients suffering from physical illnesses, according to a new systematic review in the UK. The researchers found the drugs were more effective than placebos at treating depression in these patients.
Environmental and social impact of the 'livestock revolution'
- ScienceDaily
- 10/3/16 05:00
Global meat production has tripled in the past three decades and could double its present level by 2050, according to a major report on the livestock industry. The impact of this "livestock revolution" is likely to have significant consequences for human health, the environment and the global economy, the authors...
Family mealtimes help children with asthma breathe easier, study says
- ScienceDaily
- 10/3/16 05:00
Children who have asthma are at high risk for separation anxiety, but a new study has found a home remedy that parents can use -- regular family mealtimes.
Frogs, foam and fuel: Solar energy converted to sugars
- ScienceDaily
- 10/3/16 05:00
In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant -- like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers are doing...
Heart abnormalities diagnosed in World Trade Center workers
- ScienceDaily
- 10/3/16 05:00
The World Trade Center collapse has caused potentially dangerous heart problems in responders on-site, according to new research.
How cells protect themselves from cancer
- ScienceDaily
- 10/3/16 05:00
Cells have two different protection programs to safeguard them from getting out of control under stress and from dividing without stopping and developing cancer. Now for the first time, using an animal model for lymphoma, cancer researchers have shown that these two protection programs work together through an interaction with normal immune cells to prevent tumors. Their findings may be of...
HPV vaccine protects from cancer recurrence
- ScienceDaily
- 10/3/16 05:00
A new study shows that the Gardasil vaccine reduces the likelihood of human papillomavirus-related disease recurring after teen and adult women already have had surgery to remove cancer or certain pre-cancerous changes.
Jaws -- 4 million BC

Palaeontologists have discovered evidence of how an extinct shark attacked its prey, reconstructing a killing that took place 4 million years ago.
Metallic glass yields secrets under pressure
- ScienceDaily
- 10/3/16 05:00
Metallic glasses are potentially useful materials at the frontier of materials science research. They combine the advantages and avoid many of the problems of normal metals and glasses, two classes of materials with a wide range of applications. Scientists used high pressure to probe the connection between the density and electronic structure of a cerium-aluminum metallic glass, opening up new...
Mystery solved: Why nebulae around massive stars don't disappear
- ScienceDaily
- 10/3/16 05:00
New simulations show that as the gas cloud surrounding a massive star collapses, it forms dense filamentary structures that absorb the star's radiation when it passes through them. This makes heated nebulae flicker like a candle flame.
