Small, smaller, smallest -- The plight of the vaquita

...or increases on an acceptable timescale for such a critically endangered species. According to one analysis, a single survey in 2006 or 2007 would have a probability of only 11% of detecting a 3%/year decline and a 16% probability of detecting a 10%/year decline. Achieving an acceptable probability (e.g. 95%) o...

Finding the right mix: A biomaterial blend library

...ilms. In the body, such cell-material dynamics are critically important to the outcome--determining whether a biomaterial leads to inflammation or abnormal cell growth, for example. The new study represents an innovative line of research. Working with NJCB, NIST scientists have developed a method for constru...

African wetland managers armed with new technology

...." The seminar also sought to help African users critically assess their requirements, suggest new products, identify inefficiencies and take over the process. All the training materials were consolidated on a CD and given to all African end users at the close of the session. In addition, all attendees receiv...

A surprise about our body clock

...t attack, what has not been known until now is the critically important role of bone marrow adult stem cells in repairing a damaged heart, restoring its function and enhancing the growth of new blood vessels. "These cells act like generals in a battlefield, explained Dr. Shafie Fazel, cardiac surgery resident ...

Healing the heart with bone marrow cells

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...nt tissue or organ to begin a new cancer-remains a critically important goal. The most recent figures from the Centers for Disease Control and Prevention indicate that more than 200,000 U.S. women are diagnosed with new cases of invasive breast cancer each year and that more than 40,000 of these women will die ...

Global warming may have damaged coral reefs forever

...ly already locally extinct, and six species are at critically low levels (a type of file fish, three types of butterfly fish and two damsel fish), although their decline probably started to happen soon after 1998. The survey also revealed that species diversity of the fish community had decreased by 50 per ce...

WWF captures first-ever photo of wild rhino on Borneo

...The Sumatran rhinoceros is one of the world's most critically endangered species, with small numbers found only in Sumatra (Indonesia), Sabah (on the northern end of Borneo) and Peninsular Malaysia. On Borneo, there have been no confirmed reports of the species apart from those in Sabah for almost 20 years, lea...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...chemicals to do the analyses." Perhaps the most critically important thing the method will help save is time, especially in medical diagnoses. "You might be able to get an analysis of someone's health condition in 15 minutes rather than having it take two days," says Picraux. Digital magnetofluidics will a...

Mayo Clinic study finds two genes predict outcome for breast cancer patients

...ratory data which suggests that the HOXB13 gene is critically involved in breast cancer metastases," says Dr. Goetz. "Further research is needed to determine whether more aggressive or additional treatments will improve the outcomes of women identified to be at high risk by means of this marker." Breast cance...

Cancer virus protein needed for successful infection

...t to be unimportant for its replication is in fact critically needed by the virus to initiate an infection and to reproduce. The study examined the human T lymphotropic virus type 1 (HTLV-1) and a protein it makes called p13. The protein is one of the virus' so-called accessory proteins, proteins that earlier...

Underwater listening devices yield discoveries about endangered large whales

And critically endangered North Pacific right whales have been detected acoustically in locations where they were formerly abundant but have not been seen in decades. The results from acoustic whale surveys conducted to date could pave the way for more sophisticat...

Enzyme crystal structure reveals 'unexpected' genome repair functions

...10,000 DNA bases are repaired each day, making NER critically important for cell survival and protection against mutations. NER is a critical defense mechanism that removes DNA lesions caused by the mutating effects of sunlight (ultraviolet light) and toxic chemicals. In addition, NER is critical to the succe...

New insight into machinery of immune cells' 'tentacles'

Access to antiretrovirals unlikely to reduce HIV infection rates

...oms of AIDS, the outcome on HIV prevalence depends critically on the behavior of these individuals. These results suggest that provision of ART to symptomatic AIDS patients and/or those at the earlier stages of the disease is not likely to prevent many new infections. It could even increase transmission of th...

Activation of a protein solidifies fear memory in the brain

...at within the amygdala, a brain region known to be critically involved in the creation and storage of fearful memories, selective activation of protein kinase A (PKA) is sufficient to enhance memory reconsolidation and strengthen a previously established fearful memory. Conversely, inhibiting PKA in the amygdal...

New drug could reduce tissue damage after heart attack

...ally fatal. Reducing the immediate damage is thus critically important. "We had previously invented a new mechanism of drug action for small molecules bound by target proteins. Coupled with knowledge of the structure and properties of CRP, we were able to design the CRP inhibitor. "We now propose to develop...

Newly identified mechanism helps explain why people of African descent are more vulnerable to TB

...on with certain pathogens and that turns out to be critically dependent on vitamin D. This description provides a different way to think about how human immune systems battle pathogens in general. The research team found that when Toll-like receptors in humans are stimulated by specific molecules of the tuber...

Study shows AIDS drugs cost-effective, care underfunded

The study findings are reported in the April 1 issue of Clinical Infectious Diseases, now available online. While HAART has led to dramatic decreases in illness and death of patients with HIV, it does so at...
