The plant genus Cuscuta consists of more than 200 species that can be found almost all over the world. The parasites, known as dodder, but also called wizard's net, devil's hair or strangleweed, feed on other plants by attaching themselves to their hosts via a special organ, the haustorium, and withdrawing nutrients from them. They have neither roots nor leaves. Without leaves, they are hardly able to photosynthesize. Without roots they cannot absorb nutrients and water from the soil.
The evidence is in: Nice guys and gals don’t finish last, and being a selfish jerk doesn’t get you ahead.
That’s the clear conclusion from research that tracked disagreeable people from college or graduate school to where they landed in their careers about 14 years later.
Emergency medical technicians (EMTs), military medics, and emergency room physicians could one day be better able to treat victims of vehicular accidents, gunshot wounds, and battlefield injuries thanks to a new device under development that may more accurately assess the effects of blood loss due to hemorrhage.
A new study from American University shows the results from a dietary intervention in U.S. veterans suffering from Gulf War Illness, a neurological disorder in veterans who served in the Persian Gulf War from 1990 to 1991.
The veterans’ overall number of symptoms were reduced and they experienced less pain and fatigue after one month on a diet low in glutamate, which is a flavor enhancer commonly added to foods, and that also functions as an important neurotransmitter in the nervous system.
Hypoxia is a typical characteristic of most tumors, owing to the fast consumption of oxygen by tumor tissue over the supply through malformed and abnormal tumor vasculature. Hypoxia in tumor tissue promotes the probability of tumor metastasis and endows hypoxia-tolerant tumor cells with resistance to some tumor therapies, including chemotherapy, radiotherapy, photodynamic therapy, and immunotherapy.
CHAMPAIGN, Ill. -- A study of camera-trap data from Serengeti National Park in Tanzania found that leopard population densities in the 3.7-million-acre park are similar to those in other protected areas but vary between wet and dry seasons. The fluctuations appear to be driven by the abundance of prey and how this affects interactions with other large carnivores like lions, researchers report.
University of Texas at Dallas researchers and their international colleagues have developed a method to create micro LEDs that can be folded, twisted, cut and stuck to different surfaces.
The research, published online in June in the journal Science Advances, helps pave the way for the next generation of flexible, wearable technology.
850 million people worldwide are affected by chronic kidney disease (CKD) - a worrying figure, and one that continues to rise. Treatment options for patients with CKD are multiple and often determined by the aetiology of CKD. So far, RAAS blockade (ACE inhibitors or angiotensin receptor blockers) was one of the most effective therapeutic intervention which has been shown to affect CKD disease progression. Now, SGLT2 inhibitors add significantly to the armentarium and provided another breakthrough in the management of CKD.
Pancreatic islet transplants, which revive insulin production to treat type 1 diabetes, only last an average of three years.
By learning from a groundbreaking cancer treatment strategy based on a recent Nobel Prize-winning discovery, researchers at the Georgia Institute of Technology and University of Missouri developed a new microgel drug delivery method that could extend the effectiveness of pancreatic islet transplantations -- from several years to possibly the entire lifespan of a recipient.
This is the result of the current risk assessment by the German Federal Institute for Risk Assessment (BfR). BfR President Professor Dr. Dr. Andreas Hensel: "Significantly less aluminium is absorbed through skin than previously calculated on the basis of the limited data available at the time." BfR assessed absorption via the skin, i.e. dermal absorption, of aluminium salts for the first time in 2014. "At that time, we pointed out the substantial scientific uncertainty surrounding the data and drew attention to the urgent need for research," continued Hensel.
Typhoon Maysak continued to move through the Northwestern Pacific and was closing in on Japan's Okinawa Island when NASA's Terra satellite obtained a visible image of the storm. Maysak's eye is not expected to go over the island, but pass just west of it.
CLEMSON, South Carolina - Electrifying research by Clemson University scientists could lead to the creation of lighter, faster-charging batteries suitable for powering a spacesuit, or even a Mars rover.
In a review of existing scientific studies on trendy ketogenic and intermittent fasting diets, researchers at National Jewish Health concluded that these diets do seem to help people lose weight in the short-term, and modest evidence suggests they may contribute to cardiovascular health. However, these diets also allow consumption of foods that are known to increase cardiovascular risk and are unlikely to be as effective at preventing heart disease as well-established nutritional guidelines currently recommended by health experts.
One common invasive species is so widespread that you can see it from space.
The University of Cincinnati found that satellite imagery can identify nonnative and invasive Amur honeysuckle, an ornamental shrub introduced from Asia that has spread in forests across much of the United States.
UC graduate Bridget Taylor, UC biology professor Denis Conover and UC geography professor Richard Beck used satellite imagery to find nonnative invasive Amur honeysuckle in several urban parks and cemeteries from space.
Miniaturized lasers capable of emitting over the full visible spectrum have been demonstrated to be an essential tool for versatile photonic devices ranging from sensors to full-color laser display panels. For most of these devices, multicolor microlasers with high spectral purity are of great importance because the laser emission at multiple frequencies can lead to temporal fluctuations and false signaling. Single-mode microlasers, due to the advantages of low noise and good monochromaticity, hold a promising potential in promoting the advancement of functional photonic devices.
