For nearly a century, the only bears known to reside in Missouri were on the state flag or in captivity. Unregulated hunting and habitat loss had wiped out most black bears in Missouri, Arkansas and Oklahoma by the 1920s.

Face-to-face communication begins with the eyes, a crucial factor in the design of interactive physical characters. By employing 3D printing, Disney Research, Pittsburgh has developed a new technology that is uniquely expressive, robust and adaptable for creating interactive characters' eyes.
The technology, PAPILLON, will be demonstrated at ACM SIGGRAPH 2013, the International Conference on Computer Graphics and Interactive Techniques, July 21-25 in Anaheim, California.
Under the microscope, they look like they could be from another planet, but these microscopic organisms inhabit the depths of our oceans in nearly infinite numbers.
To begin to identify where, when, and how much oceanic plankton can be found around the globe, a group of international researchers have compiled the first ever global atlas cataloguing marine plankton ranging in size from bacteria to jellyfish. The atlas was published today in a special issue of the journal Earth System Science Data.
New research conducted by Harvard scientists is laying out a roadmap to one of the holy grails of modern medicine – a cure for cancer.
As described paper recently published in eLife, Nowak, a professor of Mathematics and of Biology and director of the Program for Evolutionary Dynamics, and co-author Ivana Bozic, a postdoctoral fellow in mathematics, show that, under certain conditions, using two drugs in a "targeted therapy" – a treatment approach designed to interrupt cancer's ability to grow and spread – nearly all cancers could be effectively cured.
Researchers have long understood that genetics can play a role in how susceptible people are to contracting cholera, but a team of Harvard scientists is now uncovering evidence of genetic changes that might also help protect some people from contracting the deadly disease.
HEIDELBERG, 19 July 2013 – Scientists have identified higher levels of a receptor protein found on the surface of human breast tumour cells that may serve as a new drug target for the treatment of breast cancer. The results, which are published today in EMBO Molecular Medicine, show that elevated levels of the protein Ret, which is short for "Rearranged during transfection", are associated with a lower likelihood of survival for breast cancer patients in the years following surgery to remove tumours and cancerous tissue.
Researchers at the University of Warwick have recovered tuberculosis (TB) genomes from the lung tissue of a 215-year old mummy using a technique known as metagenomics.
The team, led by Professor Mark Pallen, Professor of Microbial Genomics at Warwick Medical School, working with Helen Donoghue at University College London and collaborators in Birmingham and Budapest, sought to use the technique to identify TB DNA in a historical specimen.
If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts. The work is published July 19 in the journal Science.
One of the most crucial problems affecting the world today is the scarcity of potable water. In a bid to make clean water available at low cost, Mr Ramakrishna Mallampati, a PhD candidate at the National University of Singapore (NUS), experimented with water treatment techniques using materials that are easily available, and came up with novel ways to purify water using the peels of apples and tomatoes. This is the first time that the peels of the two fruits have been used to remove different types of pollutants in water.
Just over a century ago, Harvey Cushing published an account of a young woman who showed unusual symptoms because her glands were making excessive amounts of something. Subsequent research has shown that the thing in question is a set of hormones known as glucocorticoids that are produced by the adrenal glands, so "Cushing's disease" is now more commonly known as hyperadrenocorticism, at least by those who can pronounce it. The condition is particularly common in dogs, particularly as the animals grow older.
UC San Francisco researchers have found a way to knock down cancers caused by a tumor-driving protein called “myc,” paving the way for patients with myc-driven cancers to enroll in clinical trials for experimental treatments.
Myc acts somewhat like a master switch within cells to foster uncontrolled growth. Until now, it has been impossible to target with drugs.
EVANSTON, Ill. --- A new low-cost, high-resolution tool is primed to revolutionize how nanotechnology is produced from the desktop, according to a new study by Northwestern University researchers.
A breakdown of the skin barrier and inflammation in the skin that occurs in eczema could play a key role in triggering food sensitivity in babies, a new study reveals. Scientists say this finding indicates that food allergies may develop via immune cells in the skin rather than the gut, highlighting eczema as a potential target for preventing food allergy in children.
There has been a "worrying" increase in alcohol related deaths among young women in England and Scotland, since the middle of the last decade, finds research published online in the Journal of Epidemiology and Community Health.
This is despite an overall fall in such deaths in both countries since the mid 2000s, say the authors, who describe the trends as a warning signal that must be heeded.
Missed diagnoses―particularly of cancer, heart attack, and meningitis―and drug errors make up the bulk of malpractice claims brought against doctors in primary care, finds an analysis of published data in the online journal BMJ Open.
The risk of litigation has not been given a great deal of attention in primary care, say the authors. But with most healthcare contacts taking place in primary care, it is important to characterise the causes and types of claims arising from these encounters, they add.
