Children hospitalized for pneumonia have similar outcomes, including length of stay and costs, regardless of whether they are treated with "big gun" antibiotics such as ceftriaxone or cefotaxime or more narrowly focused antibiotics such as ampicillin or penicillin, according to a study.
From tomatoes to pumpkins, most fruit and vegetable crops rely on pollination by bees and other insect species -- and the future of many of those species is uncertain. Now researchers are proposing a set of guidelines for assessing the performance of pollinator species in order to determine which species are most important and should be prioritized for protection.
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life.
A new report, drawing on behavioral economics literature from 2001 to 2012, has examined how cognitive factors influencing people’s choices and preferences can affect the values that they place upon ecosystem services and upon ecosystem sustainability. Ecosystem services valuation is currently central to forestry and natural resources strategies and policy-making.
Flexible workplaces may seem attractive when considering work-life balance but new research being published shows it's not unusual for firms to cash-in, profiting from our "free" time and non-professional aptitudes, experts warn.
Researchers have, for the first time, watched organic solar cells degrade in real time. This work could open new approaches to increasing the stability of this highly promising type of solar cell.
Researchers have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully converted PET into a non-toxic biocompatible material with superior fungal killing properties.
High-density lipoprotein (HDL), known colloquially as "good cholesterol," protects against dangerous deposits in the arteries. An important function of HDL is its anti-inflammatory properties. An international research team has identified a central switch by which HDL controls the inflammatory response.
Swedish researchers have found that residues of the influenza drug Tamiflu in our environment can make the influenza virus in birds resistant. This can have serious consequences in the event of an influenza pandemic. The research team will now continue their studies with a focus on alternative antiviral drugs.
Scientists have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae.
European bumblebees were introduced into Chile as pollinators. However, these socially living insects have since spread across the southern part of South America -- very much to the detriment of native species.
Researchers have identified a series of 10 genes that may signify a trifecta of benefits for women diagnosed with ovarian cancer and ultimately reflect improved survival outcomes. The research found that the 10-gene biomarker panel may identify the aggressiveness of a patient's disease, help predict survival outcomes and result in novel therapeutic strategies tailored to patients with the most adverse survival outcomes.
A stopwatch made of light can determine the duration of extremely brief electron flashes. Scientists have, for the first time, succeeded in measuring the lengths of ultrashort bursts of highly energetic electrons using the electric fields of laser light. Such electron pulses, which behave like ultrashort matter waves, provide time-resolved recordings of processes taking place in molecules and atoms, enabling elementary particles to be "filmed" in four dimensions.
An extensive European study is currently investigating whether a drug used to treat high blood pressure may also help patients with Alzheimer's disease.
Geologic processes deep inside Earth: New light on genetic makeup of Earth's deep microbial life and geochemistry of lavas
Scientists are shedding light on the genetic makeup of Earth’s deep microbial life and the geochemistry of the lavas that form the Earth’s crust.
For several years, epilepsy practitioners have questioned the U.S. Food and Drug Administration’s (FDA) definition of bioequivalence as it applies to narrow therapeutic index (NTI) drugs, such as those used for epilepsy. In response to these concerns, the FDA has sponsored 3 studies of antiepileptic drugs and also convened an advisory board to help determine which drugs are NTI.
Well-designed nutrition education programs can lead to healthier food choices among low-income families who participate in the Supplemental Nutrition Assistance Program (SNAP), according to a study.
Researchers are developing a family of generators that provide power for portable electronic devices and sensors by harnessing the triboelectric effect to capture mechanical energy that would otherwise be wasted.
Three new studies expose the high prevalence of epilepsy and other neurological disorders in US Veterans who served in Operation Enduring Freedom, Operation Iraqi Freedom and Operation New Dawn. The research conducted from these studies indicate that veterans are at a particularly high risk for traumatic brain injury (TBI), post traumatic stress disorder (PTSD), psychological non-epileptic seizures (PNES) and epileptic seizure diagnoses.
Students may soon be able to reach out and touch some of the theoretical concepts they are taught in their physics classes thanks to a novel idea.
