Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight.

Yale undergrads' Amazon trip yields a treasure trove of diversity
A group of Yale undergraduates have discovered dozens of potentially beneficial bioactive microorganisms within plants they collected in the Amazon rain forest, including several so genetically distinct that they may be the first members of new taxonomical genera.

Women exposed to negative life events at greater risk of breast cancer: BGU study
Happiness and optimism may play a role against breast cancer while adverse life events can increase the risk of developing the disease.

GOCE Earth Explorer satellite to look at the Earth's surface and core
The European Space Agency is about to launch the most sophisticated mission ever to investigate the Earth's gravitational field and to map the reference shape of our planet - the geoid - with unprecedented resolution and accuracy.

Going from ulcers to cancer
Researchers have uncovered a big clue as to why some of the bacteria that cause stomach ulcers pose a greater risk for serious problems like stomach cancer than others; it turns out these bacteria can exploit the surrounding stomach cells to protect them from the immune system.

Nano-sized 'trojan horse' to aid nutrition
Researchers from Monash University have designed a nano-sized "trojan horse" particle to ensure healing antioxidants can be better absorbed by the human body.

Dense tissue promotes aggressive cancers
New research may explain why breast cancer tends to be more aggressive in women with denser breast tissue. Breast cancer cells grown in dense, rigid surroundings step up their invasive activities, Vanderbilt-Ingram Cancer Center investigators report in the Sept. 9 issue of Current Biology.

Stellar still births
The systematics of celestial bodies apparently needs to be revised. Researchers at the Argelander Institute of Astronomy of the University of Bonn have discovered that brown dwarfs need to be treated as a separate class in addition to stars and planets.

Chips are down as Manchester makes protein scanning breakthrough
Scientists at The University of Manchester have developed a new and fast method for making biological 'chips' - technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of new drugs.

Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria.

Iowa State University experts can discuss new FDA produce irradiation rule
The Food and Drug Administration's new (Aug. 22) regulation that will allow irradiation pasteurization to be used on fresh spinach and iceberg lettuce to kill illness-causing bacteria is a step that two Iowa State University professors have long advocated.

Heavy metal link to mutations, low growth and fertility among crustaceans in Sydney Harbor tributary
Heavy metal pollutants are linked to genetic mutations, stunted growth and declining fertility among small crustaceans in the Parramatta River, the main tributary of Sydney Harbour, new research shows.

Asthma monitoring on the Web
An inexpensive web-enabled device for measuring lung function in patients with asthma and other disorders is being developed by researchers at Texas Instruments, in Bangalore, India, and co-workers. Writing in the International Journal of Biomedical Engineering and Technology, the team explains how the devise could allow physicians to monitor their patients remotely and quickly instigate medical attention in an emergency.

MSU biofilms research helps set standards for everyday products
Montana State University scientist Darla Goeres knows that there is more than one way to grow a biofilm, a fact that she uses to make sure that when a product claims it kills "99 percent" of bacteria, it really does the job.

Pay attention! Small packages may lead to overeating
Tempting treats are being offered in small package sizes these days, presumably to help consumers reduce portion sizes. Yet new research in the Journal of Consumer Research found that people actually consume more high-calorie snacks when they are in small packages than large ones. And smaller packages make people more likely to give in to temptation in the first place.

Research Finds America's Elderly Suffering Abuse
A new study concludes that nearly 13 percent of America's aged citizens suffer some form of abuse. Specifically, nine percent of adults reported they have suffered from verbal mistreatment, 3.5 percent suffer financial mistreatment, and 0.2 percent suffer physical mistreatment.

Operations research promises continued gains for HIV treatment in resource-limited countries
In the past 10 years, the global campaign to expand treatment for millions of people with AIDS living in resource-limited countries, especially in sub-Saharan Africa, has gained substantial commitments in public and private financing, and has made major strides in making treatment available to those who need it.

New approach needed to tackle child abuse and neglect
Leading child advocates have called for a new approach to tackling child abuse and neglect amid rising rates of abuse notifications and children being brought into State care.

Healthy people and enhancement drugs
Healthy people are more willing to take drugs to enhance traits that are not fundamental to their identity. According to a new study in the Journal of Consumer Research, people's willingness to take a pill or drug depends on whether the trait the drug promises to enhance is one they consider fundamental.

Seeing through tooth decay
Dental caries afflict at least 90% of the world's population at some time in their lives. Detecting the first signs of this disease, which can be lethal in extreme cases, just got easier thanks to work by researchers in India discussed in the latest issue of the International Journal of Biomedical Engineering and Technology.

How much risk can you handle? Making better investment decisions
Many Americans make investment decisions with their retirement funds. But they don't always make informed judgments. A new study in the Journal of Consumer Research introduces a new tool that investors can use to choose investments based on their financial goals and risk attitudes.

UC Davis researchers define characteristics, treatment options for XXYY syndrome
Researchers at the UC Davis M.I.N.D. Institute and The Children's Hospital in Denver have conducted the largest study to date describing the medical and psychological characteristics of a rare genetic disorder in which males have two "X" and two "Y" chromosomes, rather than the normal one of each.
