Big isn't always better when it comes to the size of male genitals.
Researchers at The Australian National University (ANU) have been looking at the breeding habits of fish, to test the theory that bigger genitals make males more attractive or successful in fathering offspring.
They found when it comes to fish, females don't find males with big genitals any more attractive than those with normal or smaller genitals.
Patients with acute myeloid leukaemia (AML) can look forward to the development of new therapies following the discovery by Walter and Eliza Hall Institute researchers of a new way to kill cells that are dangerously multiplying.
A process known as apoptosis (programmed cell death) -- which is a natural and necessary response to keep the proliferation of human cells in check -- is interrupted in cancers, including AML, leading to unchecked cell growth.
The brown-headed cowbird is nothing short of a nightmare for its hosts: If they eject the brood parasite's eggs from the nest, it punishes them by destroying their entire clutch. Researchers from the Max Planck Institute for Evolutionary Biology in Plön and Harvard University have designed a mathematical model for analyzing the interaction between avian brood parasites and their hosts. The model calculations show that birds only accept a brood parasite's eggs in their nests if they are forced to do so by retaliation on the part of the invader.
A scientific paper released today in the Journal of Antibiotics presents the pre-clinical development of Ramizol®, a first generation drug belonging to a new class of styrylbenzene antibiotics with a novel mechanism of action.
OTTAWA, May 18, 2016--A chance fossil discovery in Montana a decade ago has led to the identification of an audacious new species of horned dinosaur. The international research team that described the plant-eating dinosaur was led by a scientist at the Canadian Museum of Nature. The results are published today in the online science journal PLOS ONE.
A simple paper sheet made by scientists at Uppsala University can improve the quality of life for millions of people by removing resistant viruses from water. The sheet, made of cellulose nanofibers, is called the mille-feuille filter as it has a unique layered internal architecture resembling that of the French puff pastry mille-feuille (Eng. thousand leaves).
New data released in ECDC's Annual Epidemiological report show that since 2010, the overall syphilis rates have been going up across Europe, particularly among men. In 2014, the reported syphilis numbers were six times higher in men than in women. Almost two-thirds (63%) of the syphilis cases reported with information on transmission category were recorded in men who have sex with men (MSM).
High blood pressure could significantly raise the risk of developing the second most common form of dementia, according to a new study from The George Institute for Global Health.
The medical records of more than four million people were analysed with researchers finding heightened blood pressure was associated with a 62 per cent higher risk of vascular dementia between the ages of 30-50.
Researchers at Umeå University have developed a new method to directly follow viral infections in living organisms. This method can make infected cells produce fluorescent proteins, which means that they light up and become easier to identify. The method, which is described in the journal Scientific Reports, also makes it possible to activate other functions in infected cells, for instance to enhance the immune system.
Phenomenal quantities of valuable data are now being collected and created by UK businesses but much of its commercial potential remains untapped.
Fears of data leaks and of losing control are the key reasons why companies are hoarding data rather than sharing or trading it openly and transparently or turning it into profitable information-based products and services.
Whether water is hot in a tub or cold in a pool, it can bring immediate relief from stress or summer heat. But hot tubs and swimming pools are not always as clean as you might think, even when disinfected. In a new study in ACS' Environmental Science & Technology, scientists have found that the more these facilities are used, the more potentially harmful compounds they contain.
Preeclampsia is a pregnancy complication involving the placenta that can be serious -- even fatal -- for the mother or fetus. The only effective treatment option is premature delivery. Now for the first time, scientists have bioprinted a 3-D model of placenta tissue that mimics the organ's complex structure. The model, reported in the journal ACS Biomaterials Science & Engineering, could lead to a better understanding of preeclampsia and the development of new treatments.
A laboratory blood test developed at Johns Hopkins for the diagnosis of a rare genetic red blood cell disorder also shows promise in identifying HELLP syndrome, a life-threatening high blood pressure condition affecting 1 percent of all pregnant women that causes hypertension along with end organ damage, researchers report in the May issue of the journal Experimental Hematology.
DETROIT - Contrary to conventional wisdom, Major League Baseball pitchers who throw a high percentage of fastballs may be at increased risk for Tommy John surgery, according to research at Henry Ford Hospital in Detroit.
Researchers suggest that throwing fastballs nearly half of the time puts pitchers at risk of injury to their elbow. MLB pitchers who have undergone Tommy John surgery threw on average 7 percent more fastballs than pitchers who had no surgery.
The process of gender reassignment in transsexual individuals is complex. A new study analyses the characteristics of this collective as well as the psychological adjustment they must undergo during the process. Of the sample studied, 81.75% suffered from some type of physical aggression during their lifetime, 31.16% perceived discrimination in the workplace and 22.84% attempted suicide at least once.
