Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

... the future. "The weakening of the monsoon has a huge effect," says Weldeab, "resulting in shortages of harvests and hunger." As vegetation is cleared, the land loses its capacity to retain heat and becomes cooler. As the land cools relative to the ocean, there is a larger gradient between the ocean te...

Predators keep the world green, ecologists find

...aid in an interview. "We could see that there were huge differences between the little islands that didn't have any predators on them, and larger islands that did have predators. But we couldn't say much about where that was going to go in the future. "This article reports on the re-census," he added. "I...

Parents need to be educated about HPV vaccinations for daughters

....[1] "HPV vaccination has the potential to make a huge difference to women's lives, particularly in developing countries," said Professor Kitchener. "Cervical cancer is a major killer of women worldwide. It is not only one of the largest causes of death due to cancer, but is also responsible for a grea...

Pair of studies offer new clues to combat antibiotic resistance

...rol with antibiotics. "Antibiotic resistance is a huge problem that is only going to get worse. We need new targets, especially if we’re going to circumvent resistance," Walker says. Both research teams caution that these new approaches may be years away from human testing and clinical use. Even if effe...

Ocean 'dead zones' trigger sex changes in fish, posing extinction threat

...r waterways. These nutrients trigger the growth of huge algae and phytoplankton blooms. As these blooms die, they sink to the ocean floor where they are decomposed by bacteria and other microorganisms. Decomposition depletes most of the oxygen in the surrounding water, making it difficult for marine life ...

Computers to save unique type of American red squirrel

World faces challenge as life expectancies lengthen, scientist says

...ntries like Sweden and Italy have been having this huge debate for many years over population decline," Tuljapurkar explained. "A lot of the debate is about immigration: People have been telling them they need to increase immigration in order to keep the economy going." However, an increase in citizenry ...

The closest look ever at the cell's machines

... that we need to fill in this gap. There's still a huge amount to be learned from this data and from the methods we are developing to combine computational and biochemical investigations of the cell." "This is an important milestone towards a more global and systems-wide understanding of the cells of org...

Testes to incubate stem cells

But the risk of cancer is boosted too, so it is not just about turning on the GDNF tap indiscriminately. It must be tightly regulated, Sariola pointed out. The Dutch researchers are also hunting for the ideal c...

...abyss. In fact, the old North Sea land was once a huge area where big rivers meandered through dry plains. Now the landscape has been compressed to form a pattern of fossil alluvial sand between banks of red shale. ...

Discovery of new molecular tools for biosynthesis could lead to advances in use of pectin

..."The ability to modify pectin synthesis could have huge ramifications." In an accompanying commentary on the research, to be published later in PNAS, Antony Bacic of the Australian Centre for Plant Functional Genomics at the University of Melbourne said "the description of the biosynthetic processes invo...

Growing crops to cope with climate change

... Chief Executive, said, "Climate change presents a huge challenge for the world. Although every effort must be concentrated on reducing the impact of human activity on the environment, science should also be answering questions about how we can live in an altered climate. Research such as this helps to pr...

Potential vaccine developed for deadly leishmaniasis disease

The most common drugs used to treat leishmaniasis have serious side effects and are expensive. Symptoms of visceral leishmaniasis include fever, weight loss, and abnormalities of the liver and sple...

Researchers solve mystery of how nuclear pores duplicate before cell division

...iny molecules such as histones, which bind DNA, to huge structures such as ribosomes," he explained. To form the transport channels that span the nuclear membrane, 30 different proteins, called nucleoporins, come together in an orderly fashion and insert themselves into the nuclear envelope, where they ...

Formation of cellulose fibers tracked for the first time

Cellulose is also the main constituent of cotton, paper, wood, and animal feeds such as hay. Somerville, along with colleague David Ehrhardt and Stanford graduate student Ale...

Study finds evolution doesn't always favor bigger animals

...ing impacted by global warming. "There's still a huge debate over what drives Cope's Rule, but our study shows that climate change can undoubtedly play an important role" said Roy. For much of the past 40 million years, global climate has been exhibiting a steady cooling trend. But within the last cen...
