Researcher discovers pathway plants use to fight back against pathogens
Plants are not only smart, but they also wage a good fight, according to a University of Missouri biochemist. Previous studies have shown that plants can sense attacks by pathogens and activate their defenses.   view more (2008-04-01)

Weight loss after gastric bypass surgery may protect against infection and cancer
Another health benefit of bariatric weight-loss surgery may be a heightened immune defense against cancer and infections, a new study suggests. The results will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco.   view more (2008-06-18)

Ume'å scientist presents discoveries about natural immunity in Science
A team including scientists at UCMP (Ume'å Center for Molecular Pathogenesis), a research unit at Ume'å University, shows in last week's issue of the journal Science that the protein PGRP-LC plays a crucial role in so-called innate immunity. Professor Dan Hultmark, post-doctoral fellow... view more (2002-03-04)

Chemical Cudgel in Plants
Defense mechanisms of single-celled algae Plankton are at the bottom of the food chain in all natural bodies of water and are thus correspondingly important for their ecological balance. In the cycle of eating and being eaten it isn't only fish and whales that prey on these tiny animals and plants... view more (2000-11-29)

SEK 20 million for brain tumor research
The M'Īrit and Hans Rausing Charitable Foundation in England has awarded SEK 20 million over five years to a research team at the Faculty of Medicine at Lund University in Sweden. The team is conducting the so-called BRIGTT Project (BRain Immuno Gene Tumor Therapy), which is pursuing laboratory... view more (2003-06-25)

A clue from macaques yields evidence for impaired retroviral defense genes in humans
Researchers Harmit Malik and Michael Emerman and colleagues at the Fred Hutchinson Cancer Research Center have found that a surprisingly large fraction of humans may be impaired in the function of a recently discovered arm of the body's defense against invading retroviruses such as HIV.   view more (2006-01-10)

Complex questions asked by defense lawyers linked to convictions in child abuse trials
Defendants in child abuse cases are more likely to be convicted if their defense lawyer uses complicated language when interrogating young victims according to new research out of the University of Toronto and the University of Southern California.   view more (2008-07-21)

Bank robbers and terrorists
Identifying suspected bank robbers, enemy troops, or terrorists is Lena Klasén's field of research. In scientific terms this is called image analysis of complex, articulated, and deformable objects related to the fields of crime and defense. Lena Klasén has a history at the Swedish... view more (2002-11-27)

Nonvenomous Asian snakes 'borrow' defensive poison from toxic toads
Most snakes are born with poisonous bites they use for defense. But what can non-poisonous snakes do to ward off predators?   view more (2007-01-31)

Study identifies new tumor suppressor
A protein called HLJ1 may work as a novel tumor suppressor in non-small-cell lung carcinoma.   view more (2006-06-21)

Study reveals body's defense mechanism worsens asthma symptoms
MUHC scientists have discovered that our body's own defense mechanism causes some of the most serious asthma symptoms.   view more (2005-08-12)

New evidence of battle between humans and ancient virus
For millennia, humans and viruses have been locked in an evolutionary back-and-forth -- one changes to outsmart the other, prompting the second to change and outsmart the first.   view more (2008-07-22)

TLR4 gene found to protect against tumor development
A new study finds that a gene which plays an important role in immune function, known as toll-like receptor 4 (TLR4), may also play a critical role in suppressing chronic lung inflammation and tumor development in mice.   view more (2005-12-08)

Fetal fat and “red spots” in newborn babies a defense against bacterial attacks
It is common that babies are born with fetal fat and develop red spots on their skin. Pediatricians have always explained this as a passing and normal skin reaction in newborn children. Now Giovanna Marchini at the Karolinska Hospital, Sweden, together with her research team, has discovered that... view more (2003-03-03)

Researchers at the University of Illinois at Chicago are unraveling the biochemical mechanism by which functional foods combat cancer.   view more (2005-07-11)

Insect warning colors aid cancer and tropical disease drug discovery
Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama.   view more (2008-07-09)

Scholar explores the question of who speaks for science
What role can scientists play in public decisions about the development and deployment of weapons systems? As the United States continues to commit its troops and technology around the world, this question is worrisome to the public and to concerned scientists alike.   view more (2007-02-20)

Mosquito immune system examined
Mosquitoes employ the same immune factors to fight off bacterial pathogens as they do to kill malaria-causing Plasmodium parasites, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health.   view more (2006-06-09)

Role of protein in immune response may aid HIV research
A family of proteins that serve as the body's first line of defense against bacterial infections may provide a lifeline for individuals with compromised immune systems, according to researchers at the Indiana University School of Medicine - Northwest.   view more (2006-07-31)

Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless
Concentrated chemicals derived from green tea dramatically boosted production of a group of key detoxification enzymes in people with low levels of these beneficial proteins, according to researchers at Arizona Cancer Center.   view more (2007-08-13)

Researchers Find Defects in Adult Stem Cell Niche May Cause Breast Cancer
Researchers at Georgetown's Lombardi Comprehensive Cancer Center have found that the onset of breast cancer may be due to defects in somatic adult stem cell niches that exist long before tumors develop.   view more (2005-10-05)

Team IDs weakness in anthrax bacteria
MIT and New York University researchers have identified a weakness in the defenses of the anthrax bacterium that could be exploited to produce new antibiotics.   view more (2008-01-25)

New Saliva Test May Help Dentists Test for Breast Cancer
Breast cancer is the second leading cause of death among women in the United States. In 2006, the American Cancer Society estimated that there would be 212,920 new cases of invasive breast cancer, and in that year, 40,970 women would die from it.   view more (2007-03-21)
