3:01 PM | Virgin Births: Here Is Why Males Are Still Not Irrelevant
Evolution has endowed females of certain species of amphibians, reptiles and fish with the ability to clone themselves and perpetuate offspring without males. It has even happened more recently but these virgin births don't mean males are unneeded. Fertilization is still ensuring the survival of the maximum number of healthy offspring.A species can increase its numbers faster in harsh environments when its females do not have to find worthy males and scientists have speculated that this […]

2:52 PM | Chemobrain: Even A Cancer Diagnosis Affects Cognitive Function
Breast cancer patients often display mild cognitive defects even before chemotherapy and doctors are attributing that to a kind of preemptive post-traumatic stress disorder induced by diagnosis of the disease.Studies have shown that cancer patients often exhibit mild attention deficit and some decrease in memory and other basic cognitive functions. The phenomenon has generally been attributed to putative side-effects of chemotherapeutic drugs on the brain, and the condition is therefore […]

2:00 PM | Physician Support For Obamacare In California Is Along Party Lines
A survey of California doctors found that a majority of the 525 who responded believe the Patient Protection and Affordable Care Act (ACA, also called Obamacare) will steer the country's health care in the right direction, but California has only 28 percent Republicans so that isn't a huge surprise. Doctors were on the side of their political affiliations but were also distinctly divided by medical specialties. Private practices are on the decline and independent business owners are strongly […]

1:30 PM | How Salmonella Survives Macrophage's Acid Attack
Macrophages destroy bacteria by engulfing them in intracellular compartments, which they then acidify to kill or neutralize the bacteria. Some pathogenic bacteria, such as Salmonella enterica, have evolved to exist and even grow within these acidified compartments. Yet, how Salmonella responds to the acidic environment and how that environment affects the virulence of this pathogen are unclear. New research reveals that Salmonella fights acid with acid, by lowering the pH of its own interior […]

1:14 PM | LP Resurgence: The Reasons Behind Vinyl's Unlikely Comeback
In a music buying industry now dominated by iTunes and music streaming sites such as Spotify, Napster, Pandora and Jay-Z’s recently released Tidal, the CD and physical music store are reportedly in sharp (and potentially terminal) decline. But a curious development in music consumption has seen vinyl, the format ostensibly rendered extinct by the compact disc with its “perfect” digital sound, make an unlikely, but significant cultural and commercial comeback. read more

1:00 PM | Typhoon Haiyan May Contaminate Philippines Aquifer For Years
In 2013, Typhoon Haiyan killed more than 6,000 people and destroying nearly $3 billion worth of property in the Philippines. While the country is still recovering from the storm, researchers have found that an aquifer on the island of Samar inundated with salt water by the storm surge could remain undrinkable for up to 10 years - a second aquifer on the island that was also inundated has recovered much more quickly. Geology and infrastructure play key roles in determining whether aquifers that […]

12:30 PM | Genetic Modification Led To Maize Roots Evolving To Be More Nitrogen Efficient
Genetic modification of maize over the last century has led to desirable shoot characteristics and increased yield - and that likely contributed to the evolution of root systems that are more efficient in acquiring nutrients, such as nitrogen, from the soil, according to a new study. About half of the yield gains in commercial corn in the last 100 years has come from improved plant genetics, explained Larry York, a postdoctoral research fellow at the University of Nottingham. The other […]

12:12 PM | Grab Your Torch and Pitchforks
I always find it disturbing to see people, especially in large crowds, apparently acting according to primitive emotions rather than enlightened thinking. It makes it seem like the veneer of civilization is paper thin, and we are not far removed from apes huddled around the monolith and hitting each other over the head with bones. [...]

12:07 PM | How the Developing Brain Moves from Cooties to Crushes
For the first time, researchers have found the signals for “cooties” and “crushes” in the developing brain. In a new study, cognitive neuroscientists have highlighted how the brain responds to gender across a range of ages. Led by Eva Telzer of the University of Illinois, Urbana-Champaign, the researchers found that young children had heightened brain […]

11:30 AM | Psychology students are seduced by superfluous neuroscience
It seems as though neuroscience is particularly popular and seductive. Not only is the discipline enjoying some eye-spinningly massive new grants, there are also ever more brain-branded products (like brain games and brain drinks), there are new disciplines like neuroleadership, and there's a growing obsession about the brain among many journalists, many of whom invoke brain science in odd contexts (check out "The neuroscience of ISIS" for a recent example).This atmosphere has led to a […]

2:25 AM | Professional Golf: For Most It Is A Lonely Life On A Meager Income
If you just watched the Master's Tournament in Augusta, Georgia, you saw the second-youngest player ever to win. That is a pretty good way for a young man to spend the next year.But for most golfers, like most young baseball players, the reality is much different. An EPGA tour player for 12 years commented to Dr. John Fry of Myerscough College on the life: "The word that jumps in my head is lonely".read more

9:53 PM | LEM - Newly Discovered Protein Boosts Immunity To Cancer
A newly discovered protein plays a central role in promoting immunity to viruses and cancer, according to experiments in mice and human cells. The hitherto unknown protein, which the researchers named lymphocyte expansion molecule, or LEM, modulates the proliferation of human T cells as well as in mice, by promoting the proliferation of cytotoxic T cells, which kill cancer cells and cells infected with viruses. The discovery was unexpected because the new protein had no known function […]

9:44 PM | Do All These Health Awareness Day Campaigns Actually Help Anyone?
In 2014, there were almost 200 health awareness days, weeks or months on the 2014 U.S. Department of Health and Human Services' National Health Observances calendar.  Since there are only 250 days in a working year, that means one day each week was not given over to some kind of health awareness effort. H.H.S. says their mission is to advocate for "evidence-based" interventions for health problems, so what evidence did they use that 200 health "awareness" campaigns were making a […]

9:12 PM | No Batteries Required - New Camera Runs Forever
A research team has created a prototype video camera that is fully self-powered. Solar panels and digital cameras obviously have different purposes - one converts light to power while the other simply measures it - but both are constructed from essentially the same components. At the heart of any digital camera is an image sensor, a chip with millions of pixels. The key enabling device in a pixel is the photodiode, which produces an electric current when exposed to light. This mechanism […]

8:49 PM | SAYE: Herbal Tea Combats Malaria
Malaria is a critical health problem in West Africa, 11 percent of deaths are related to it, but for a variety of reasons they have more confidence in alternative medicine than they do modern health care practices.  However, some herbal medicines work and an analysis of the pharmacological properties of an herbal medication derived from Cochlospermum planchonii (a shrubby weed known as N'Dribala), Phyllanthus amarus and Cassia alata shows that it may be the case with SAYE, which means […]

8:00 PM | Recurrent Miscarriages Could Be Linked To Body Clock Genes
It is estimated that 5% of women experience two clinical miscarriages and approximately 1% suffer three or more losses.  Researchers at the University of Warwick and University Hospitals Coventry and Warwickshire (UHCW) NHS Trust have found that body clock genes could affect women's ability to have children. The study pinpoints how body clock genes are temporarily switched off in the lining of the womb to allow an embryo to implant. Timing of this event is critical for […]

7:30 PM | Why Not Ask The Public What Works To Get People Into Clinical Trials?
While a debate was raging between scientists and government regulators on how best to explain to patients the risks of participating in clinical research studies that compare standardized treatments, a team of bioethicists boldly went where no experts had gone before -- to the public. The response? Keep it simple, but always ask permission, even when the research only involves gathering data from anonymized medical records. read more

6:39 PM | Could maple syrup help cut use of antibiotics?
Another reason to have those waffles… well maybe. Researchers have found that a concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics. In an ever increasing antibiotic resistant world, this news is almost as sweet as the syrup (okay no more bad puns). The findings suggest that combining maple syrup extract with common antibiotics […]
