Doctor revalidation needs to address 7 key issues for success, claims report

New research launched today, 1st September 2014, has concluded that there are seven key issues that need to be addressed to ensure the future success of doctor revalidation, the most profound revision in medical regulation since the Medical Act of 1858. read more

Climate Cycles, Climate Mechanisms and Determining Accurate Dates

Guest opinion: Dr. Tim Ball | When Did It Occur? Lack of information is a major problem in reconstructing and understanding climate and climate mechanisms. H.H.Lamb gave it as his reason for creating the Climatic Research Unit (CRU). “…it was clear that the first and greatest need was to establish the facts of the past…

National Geographic’s Warming Warning – 10 Years Later

Geoff Sherrington writes: National Geographic Magazine had a Global Warming issue in September 2004. New instruments have given new data. By planning now, NatGeo can make a revised issue 10 years later, in September 2014. The 2014 edition should aim to correct what is now known to be wrong or questionable in the 2004 edition.…

A new synthetic amino acid for an emerging class of drugs

One of the greatest challenges in modern medicine is developing drugs that are highly effective against a target, but with minimal toxicity and side-effects to the patient. Such properties are directly related to the 3D structure of the drug molecule. Show More Summary

Discovery reveals how bacteria distinguish harmful vs. helpful viruses

When they are not busy attacking us, germs go after each other. But when viruses invade bacteria, it doesn't always spell disaster for the infected microbes: Sometimes viruses actually carry helpful genes that a bacterium can harness to, say, expand its diet or better attack its own hosts. read more

Why sibling stars look alike: Early, fast mixing in star-birth clouds

In other runs of the simulation, Krumholz and Feng observed that even clouds that do not turn much of their gas into stars—as the Sun's parent cloud probably didn't—still produce stars with nearly-identical abundances. "We've provided...Show More Summary

Mixing in star-forming clouds explains why sibling stars look alike

Krumholz and UC Santa Cruz graduate student Yi Feng used supercomputers to simulate two streams of interstellar gas coming together to form a cloud that, over the course of a few million years, collapses under its own gravity to make a cluster of stars. Show More Summary

Antarctic sea-level rising faster than global rate

A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by 2cm more than the global average of 6cm. Researchers at the University...Show More Summary

Changing global diets is vital to reducing climate change

A new study, published today in Nature Climate Change, suggests that – if current trends continue – food production alone will reach, if not exceed, the global targets for total greenhouse gas (GHG) emissions in 2050. The study's authors say we should all think carefully about the food we choose and its environmental impact. Show More Summary

A new way to diagnose malaria

CAMBRIDGE, MA -- Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye, and looks under a microscope for the Plasmodium parasite, which causes the disease.

Evidence mounting that older adults who volunteer are happier, healthier

Older adults who stay active by volunteering are getting more out of it than just an altruistic feeling -- they are receiving a health boost too, researchers report. Volunteering is associated with reductions in symptoms of depression, better overall health, fewer functional limitations, and greater longevity.

Hydrogen powers important nitrogen-transforming bacteria

Nitrite-oxidizing bacteria can use hydrogen as an alternative source of energy, an international team of researchers has found. The oxidation of hydrogen with oxygen enables their growth independent of nitrite and a lifestyle outside the nitrogen cycle.

Reducing water scarcity possible by 2050

Water scarcity is not a problem just for the developing world. Increased water-recycling and improved irrigation techniques are among many strategies identified in North America as key to successfully reducing global water scarcity.Show More Summary

Intense Exercise during Long Space Flights Helps Astronauts Protect Aerobic Capacity

Many astronauts experience a dip in aerobic capacity during long space flights, which can impair their ability to perform complex and demanding routine tasks. In a new article, NASA researchers find that regular, intense in-flight exercise helps preserve cardiovascular stamina.

Not all phytoplankton in the ocean need to take their vitamins

Some species of marine phytoplankton, such as the prolific bloomer Emiliania huxleyi, which can grow so big it can be seen from space, can grow without consuming vitamin B1 (thiamine), researchers have discovered. Until now, many marine...Show More Summary

Obese or overweight teens more likely to become smokers

Weight status has no correlation with alcohol or marijuana use but is linked to regular cigarette smoking, a study examining whether overweight or obese teens are at higher risk for substance abuse has found. The authors note that the idea that smoking helps with weight reduction or appetite suppression is widely held, but is not true. Show More Summary

Arctic Ice and the AMO

By Paul Homewood   David Rose’s piece in the Mail on Sunday has already been picked by WUWT and Bishop Hill, amongst others. But I want to concentrate on one aspect, that of cycles. The Mail report: However, Dr Hawkins added that the decline seen in recent years was not caused only by global warming.…

Does Antarctic Sea Ice Growth Negate Global Warming Theory?

LA Times making frantic excuses Eric Worrall writes: The LA Times has published an article which asks whether the faithful should worry about the rapid growth of Antarctic sea ice, an observation which sharply contradicts model predictions that the ice should all be melting away. Naturally the article concludes that their readers should not be…
