Fast-track dieting can be successful long-term

People who lose weight quickly are no more likely to pile the kilos back on than dieters who lose them slowly, according to a new study. Weight-loss guidelines have long counselled that kilos shed too quickly are likelier to creep back than those lost at a slower pace. But a new Australian study, published in The Lancet Diabetes & Endocrinology, found that over the long term, fast-track and slow-track dieters were equally likely to regain most of the weight they … Continue reading

Honeysuckle tea can treat Influenza A viruses, and possibly Ebola

honeysuckle

Researchers have discovered the world’s first ‘virological penicillin’ in a molecule found in honeysuckle. The sweet-smelling honeysuckle plant (Lonicera japonica) has been used for generations in traditional Chinese medicine to treat influenza infections. While it’s been known to block the replication of the influenza virus, the mechanism and active components in the plant have remained a mystery until now. In a new study published in Cell Research, scientists from the Nanjing University in China studied the honeysuckle plant and identified a plant microRNA called … Continue reading

Earth’s magnetic field could flip much faster than previously predicted

A new study suggests that Earth’s magnetic field could take just 100 years to flip – and there’s evidence it could happen again in a couple of thousand years. We think of north and south as being pretty constant, but the Earth’s magnetic field has flipped many times throughout the planet’s history, generally without causing huge catastrophes. The Earth’s magnetic field is dipole, like that of a magnet, which means it has two opposite poles. Usually this magnetic field maintains … Continue reading

Dark Flow From Other Universe Engulfing Galaxy Clusters

Our universe is becoming more mysterious with the attempts of understanding it deeply. The Galaxies are moving away from each other because of expanding universe which is now well accepted concept. Now, the astronomers have also observed that the galaxy clusters are constantly moving towards a point present in southern constellation Centaurus and Hydra. The source of this attraction is doubted to be present outside our observable universe. The astronomers have no idea what is causing this mysterious motion of … Continue reading

Climate change: Models ‘underplay plant CO2 absorption’

Global climate models have underestimated the amount of CO2 being absorbed by plants, according to new research. Scientists say that between 1901 and 2010, living things absorbed 16% more of the gas than previously thought. The authors say it explains why models consistently overestimated the growth rate of carbon in the atmosphere. But experts believe the new calculation is unlikely to make a difference to global warming predictions. The research has been published in the journal, Proceedings of the National … Continue reading

Temperature and water vapor on an exoplanet mapped

A team of scientists using NASA’s Hubble Space Telescope has made the most detailed global map yet of the glow from a planet orbiting another star, revealing secrets of air temperatures and water. The map provides information about temperatures at different layers of the world’s atmosphere and traces the amount and distribution of water vapor on the planet. The findings have ramifications for the understanding of atmospheric dynamics and the formation of giant planets like Jupiter. “These measurements have opened … Continue reading

Icebergs once drifted to Florida, new climate model suggests

Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographer Alan Condron of the University of Massachusetts Amherst has shown that icebergs and meltwater from the North American ice sheet would have regularly reached South Carolina and even southern Florida. The models are supported by the discovery of iceberg scour marks on the sea floor along the entire continental shelf. Such a view of past meltwater and iceberg movement implies … Continue reading

How many Galaxies can be seen without a telescope?

spiralgalaxyanimation

You can see only four other galaxies besides the Milky Way without using a telescope! These are, the Large and Small Magellanic Clouds which are easy to see from the southern hemisphere and then there is the Triangulum Galaxy which is one of the most distant objects that can be seen by eye. However, the most beautiful galaxy we can see with the naked eye is the nearby Andromeda Galaxy, also called M31. Andromeda and the Trangulum are both spiral galaxies, like our … Continue reading

For Fecal Transplants, Frozen Poop Just as Good

For people suffering with the intestine infection Clostridium difficile, the treatment sometimes referred to as a “poop transplant” may work just well with fresh or frozen fecal matter, researchers say. In a new study, 10 patients with C. diff infections who received a transplant using frozen fecal material from healthy donors responded just as positively as the 10 patients treated with fresh fecal material, the researchers said. The procedure is intended to transplant beneficial microbes found in fecal matter. Moreover, … Continue reading

Undulatus asperatus

Undulatus asperatus is a cloud formation, proposed in 2009 as a separate cloud classification by the founder of the Cloud Appreciation Society. If successful it will be the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization. The name translates approximately as “roughened or agitated waves”. The clouds are most closely related to undulatus clouds. Although they appear dark and storm-like, they tend to dissipate without a storm forming. The ominous-looking clouds have been … Continue reading

There’s half as much dark matter in the Milky Way as we thought

milky way2

Scientists have long known that everything we see only makes up a tiny part of the Universe – the majority of it is hidden to us. “Stars, dust, you and me, all the things that we see, only make up about 4 percent of the entire Universe,” said lead researcher Prajwal Kafle from the University of Western Australia node of the International Center for Radio Astronomy Research (ICRAR) in a press release. “About 25 percent is dark matter and the … Continue reading

This Is What a Dead Star Looks Like

Ever wondered what a dead star looks like? Then have a gander at the image above — you’re looking at “Kepler’s Supernova”. First spotted 410 years ago today, it’s the most recent supernova to have been observed without sky-gazing equipment within our own galaxy. Named after Johannes Kepler, the German astrologer and mathematician who first observed the event, Kepler initially thought that the supernova was a brand new star, as it appeared brighter than any other planet in the sky. … Continue reading

This new veggie burger bleeds like meat

vegi burger

Here’s one for all those vegetarians out there who sometimes just really feel like a good ol’ hamburger – a veggie burger complete with what looks like a perfectly cooked, medium rare beef patty. The burger is the brainchild of biochemistry professor Patrick Brown from Stanford University in the US, and it’s now being manufactured by his food company, Impossible Foods. The secret ingredient is called heme, or ‘plant blood’, which is an organic molecule found in the protein leghemoglobin … Continue reading

‘Giant leap’ to type 1 diabetes cure

The hunt for a cure for type 1 diabetes has recently taken a “tremendous step forward”, scientists have said. The disease is caused by the immune system destroying the cells that control blood sugar levels. A team at Harvard University used stem cells to produce hundreds of millions of the cells in the laboratory. Tests on mice showed the cells could treat the disease, which experts described as “potentially a major medical breakthrough”. Beta cells in the pancreas pump out … Continue reading

How infectious is Ebola?

ebola infection rates

So there’s a case of Ebola in the US, and the disease has already killed 70 percent of those it infected in West Africa. Is this the beginning of the end for humanity? Not even close, and here’s why. The US case of Ebola is the first to be identified outside of Africa. The patient, who has now died from the disease, didn’t know that he was infected straight away, so wasn’t quarantined by the Texas Health Presbyterian Hospital in … Continue reading

Viruses can turn their DNA from a solid to a liquid to infect your cells

viral DNA

New research has found that viruses have a remarkable biological ability – they can transform their DNA from a glassy solid into a fluid-like state to help them infect cells.A fluorescence image of viral DNA complexes in the cytoplasm of a cell. Although viruses infect our cells with their DNA all the time, it’s a process that scientists have so far struggled to understand – viral DNA is so tightly packed inside its protein shell that, technically, it can barely … Continue reading

Study reveals messenger molecules in cell walls can double as hormones

Researchers have discovered that some common messenger molecules in human cells double as hormones when bound to a protein that interacts with DNA. The finding could bring to light a class of previously unknown hormones and lead to new ways to target diseases – including cancers and a host of hormone-related disorders. Published in the Oct. 6 edition of Proceedings of the National Academy of Sciences, these results were made possible, in part, by X-ray experiments at the Department of … Continue reading

Researchers take cells from chrysalis and grow butterfly wings in the lab

A pair of researchers, one from Oxford University, the other with the Natural History Museum in London, has found a way to grow butterfly wings in their lab. In their paper published in Bioinspired, Biomimetic and Nanobiomaterials, Helen Townley and Andrew Parker describe the transparent nature of certain butterfly and beetle wings and their efforts to reproduce them using cell cultures to grow colored materials. Many butterfly wings, it turns out, are not actually colored by pigments or dyes—instead, their … Continue reading
