Dig deeper to find Martian life

...f recovering living cells. We have found that this suspected frozen sea in Elysium represents one of the most exciting targets for landing a probe, as the long-term survival of cells here is better than underground in icy rock. This could be crucial for the scientists and engineers planning future Mars mission...

Researchers show that veins stiffen as we age

...ical Association " Based on previous research, we suspected that the veins of the older adults would be less flexible than those of the younger adults," Farquhar said. "But we didn't know if that might be due to a functional process, such as a chronic constriction of the muscles around the veins, or if this d...

How fish mend a broken heart

...te cardiac muscle after major injury. They further suspected that illumination of the fishes' ability might offer important insights into "how heart regeneration is naturally optimized." In the current study, they found that heart regeneration proceeds through two coordinated stages. First, a mass of undiffe...

Key to zebrafish heart regeneration uncovered

...Whitehead Foundation. Scientists previously had suspected that zebrafish regenerated their heart tissue by the direct division of existing cardiac muscle cells adjacent to the injury, Poss said. However, Poss and colleagues found that the process more closely resembles what happens when a salamander rege...

Neuron cell stickiness may hold key to evolution of the human brain

...of the animal kingdom," said Rubin. "We have long suspected that it would be a combination of DNA sequences coding for genes and DNA sequences that control when genes are switched on or off. In this study by comparing the entire genome of many organisms to that of humans we were able to identify a series of ...

Fake pesticides threaten food safety

... DEFRA is currently investigating two companies suspected of acting illegally. Jean Train, spokesperson for the Pesticides Safety Directorate, told C&I "We are in the process of gathering evidence with intention to prosecute". This will add to the list of successful action PSD have already taken against...

With fruit fly sex, researchers find mind-body connection

...y. McKeown wanted to settle the debate. McKeown suspected that multiple genes shape behavior and that doublesex played a role. But experimenting with doublesex is difficult. When both copies of the gene are removed ?a powerful way to test gene function ?flies have the physical features of both sexes. As a r...

Studies find general mechanism of cellular aging

...ates increased expression with age, the scientists suspected the gene played a similar role in aging. The researchers developed strains of mice that were either deficient in p16INK4a (the gene was deleted, or 'knocked out") or genetically altered to have an excess of the protein to a degree seen in aging. Ac...

Firefighters face increased risk for certain cancers

...s avoid inhalation and skin exposures to known and suspected occupational carcinogens," says Lockey, professor of environmental health and pulmonary medicine at UC. "In addition, firefighters should meticulously wash their entire body to remove soot and other residues from fires to avoid skin exposure." ...

Taking 'chips' to the next level of gene hunting

...mes to break. Transposable elements long have been suspected of playing a role vital to disease-causing mutations in people. Boeke hopes that the TIP-chip eventually can be used to look for such mutations in people. The new TIP-chip contains evenly sized fragments of the yeast genome arrayed in dots left t...

Researchers make nanosheets that mimic protein formation

...en S-layer proteins are highly anisotropic, and we suspected this was also a feature of the nanoparticles," Glotzer said. "Computer simulations allowed us to further develop and test this hypothesis." Post doctoral researcher Zhenli Zhang of Glotzer's group tried various combinations of forces based on info...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

..."A subsequent validation group of 10 patients with suspected Alzheimer's and 18 healthy and demented control subjects turned up similar results," said Relkin. "Based on their clinical symptoms, we found the new screen to have 93 percent sensitivity to probable cases of Alzheimer's and a 90 percent accuracy in ...

New engineered drug may offer prolonged arthritis relief

...rthritis in the joint. Given the immune system's suspected role in osteoarthritis, scientists have suspected that the interleukin-1 receptor antagonist drug, which is known to block IL-1 activity, might have v...

Cellular traffic backups implicated in skeletal malformations

... craniofacial malformations. Realistically, nobody suspected that these so-called 'housekeeping genes' are responsible for that sort of phenotype." "For me, it's fascinating that the gene we have found was the least expected." It turns out that the zebrafish mutant has a human counterpart, making the crush...

Highly concentrated botulinum preparation for cosmetic injections can result in severe illness

...linum toxin injections. On November 27, 2004, four suspected botulism case-patients with a link to cosmetic bot...olleagues investigated various aspects of the four suspected cases of botulism. They found that clinical characteristics of the four case-patients were consisten...

Spike in testicular cancer is focus

... collect and evaluate information on various major suspected risk factors, such as past medical history, history of hernia, venereal diseases, and any medication with androgens and other hormones. They will also examine lifetime occupational history, tobacco smoking, alcohol consumption and dietary information...

Researchers reveal mystery of bacterial magnetism

...Kathleen O'Connor. In the past, scientists had suspected that being magnetic helps a bacterium find the oxygen concentrations it prefers more quickly by swimming only up and down in the earth's magnetic field rather than randomly in all directions. An analogy would be a blind-folded mountain climber searc...

Insulin receptor stops progression of Alzheimer's disease

... fewer lesions in the brain. "If the diagnosis is suspected or patients are in the early phases of AD, there's a good possibility they could get treatment that will help them. It's possible that in the moderate phase, treatment will also help, but more work needs to be done to show that," de la Monte says. ...

Search on for treatment of slow-healing wounds

... clinic treating up to 100 patients daily, Wolcott suspected biofilms might play a role in his patients' persistent wounds. Tissue samples analyzed by the CBE from Wolcott's clinic revealed that 60 percent contained biofilms, compared with a mere 6 percent in acute wounds, such as cuts. Previous center r...

Crohn's disease gene identified

...s, especially Ashkenazi Jews, scientists have long suspected a significant genetic component. According to senior author Judy H. Cho, M.D., associate professor in the Departments of Medicine and Genetics at Yale School of Medicine, the team found that mutations in a receptor gene associated with ...
