Hemin improves adipocyte morphology and function by enhancing proteins of regeneration

Obesity has escalated in every segment of the population including children, adolescences and adults. In obesity, impaired lipid and glucose metabolism are implicated in the conundrum of cardiometabolic complication. Heme-oxygenase is a cytoprotective enzyme that has been recently shown to improve glucose and lipid metabolism in diabetic, hypertensive and obese animals. Thus substances capable of enhancing heme-oxygenase may be explored as novel remedies against cardiometabolic complications arising from excessive adiposity.

This work was supported by a grant from the Heart & Stroke Foundation of Saskatchewan, Canada to Dr. Joseph Fomusi Ndisang.

Special Issue -- Rosetta Begins Its Comet Tale

This special issue of Science highlights new data from the Rosetta spacecraft, which is currently in close orbit around the Jupiter family comet known as 67P. The spacecraft, which receives funding from the European Space Agency, NASA, and other member states, dropped its lander, Philae, off on the surface of the comet in November -- an event that was celebrated in Science’s 2014 Breakthrough of the Year.

Gamma-ray sources detected in large magellanic cloud

The High Energy Stereoscopic System (H.E.S.S.) Collaboration has identified three sources of high-energy gamma rays in the nearby Large Magellanic Cloud (LMC) galaxy: a pulsar wind nebula, a supernova remnant, and a superbubble.

Before tools, a human-like hand in hominins?

The first stone tools don’t appear in the archaeological record until about 2.6 million years ago, but researchers have discovered that Australopithecus africanus as well as other, younger hominins had human-like hands -- capable of precision grips, or “squeeze” gripping, with an opposable thumb -- as early as 3.2 million years ago.

Chronic infection shortens lives and telomeres in birds

Great reed warblers with chronic and mild malaria infections have shorter lives and fewer offspring than uninfected birds, according to a new study by Muhammad Asghar and colleagues. Infected warblers also have significantly shorter telomeres, which are the protective end caps on chromosomes that gradually wear away over time.

Oxytocin improves social behavior in mice with autism

Olga Peñagarikano and colleagues show in a mouse model of autism that oxytocin can markedly improve social behavior, a benefit that can become long-lasting with early treatment. Oxytocin, a hormone that helps build social bonds and trust in animals, has generated intense interest as a potential treatment for autism spectrum disorder, but clinical trials so far have delivered mixed results.

Next-generation sequencing offers insight into how species adapt to climate change

Next-generation sequencing allows for the creation and analysis of vast amounts of data about populations and their responses to shifting environmental conditions, including climate change. These data can provide fine-scale information at the genomic level into populations’ adaptations to changing circumstances. Despite the potential usefulness of next-generation sequencing for environmental scientists, it is a costly tool, and funding has yet to equal the value that it may provide.

New Laser-patterning Technique turns metals into dupermaterials

By zapping ordinary metals with femtosecond laser pulses researchers from the University of Rochester in New York have created extraordinary new surfaces that efficiently absorb light, repel water and clean themselves. The multifunctional materials could find use in durable, low maintenance solar collectors and sensors.

Arid air and language tonality

Climatic conditions such as temperature and humidity that affect the performance of the vocal folds may constrain development of complex tones in language to warm, humid regions, according to a study. Dry air can decrease the precision of pitch and tone produced by the vocal folds of the larynx, possibly impairing production of precise tones that can convey meaning in some languages and possibly acting as a climatic constraint on language development.

Deforestation and greenhouse gas emissions reductions in Indonesia

A recent moratorium on deforestation activities in Indonesia has reduced greenhouse gas emissions but not to a level sufficient to reach current targets, according to a study. In May 2011, Indonesia instituted a two-year ban on issuing new concession licenses for logging and conversion of primary forests and peat lands to oil palm or pulp and paper tree plantations.

Canine distemper and Serengeti lions

A study in Tanzania suggests that domestic dogs may have spread canine distemper virus (CDV) to Serengeti lions but that subsequent infection peaks may have been caused by other carnivore species. CDV typically infects domestic dogs, but a 1994 Tanzania epidemic resulted in the die-off of approximately 30% of lions in the Serengeti ecosystem.

A study of more than 5,000 Himalayan mountain climbing expeditions involving climbers from 56 countries finds that expeditions from countries with hierarchical cultures had more climbers reaching the summit, but also more climbers dying along the way, than expeditions from countries with weak hierarchical values, a finding that illustrates the benefits and risks of hierarchical culture in high-stakes group dynamics.

Swelled tissues burst limits of microscope

There are limits to how well a light microscope can magnify the tiny details in a cell or tissue. So why not blow up the biological material itself to a larger size? That’s the solution proposed by Fei Chen and colleagues, who have designed a way to expand cells and brain tissue using a swellable polymer.

Opinions about ability might affect women’s academic participation

The results of a national survey in the United States suggest that the representation of women in academia might reflect peoples’ general attitudes about what it takes to excel in various disciplines. Specifically, researchers suggest that fewer women participate in fields that are perceived to require innate or raw talent -- and that more women gravitate to fields in which empathy or hard work is perceived to be key.
