FDA Unveils Biosimilars Guidance 6

Posted by timothy
from the well-it's-kind-of-like-kale dept.
ananyo writes "The U.S. Food and Drug Administration has released its long-anticipated draft guidance for drug makers interested in making generic forms of biological drugs such as enzymes and antibodies. The move could open the door for cheaper versions of some of medicine's most expensive drugs, but it is still unclear how many companies will be willing to tackle the challenges and uncertainties of making 'biosimilar' drugs. Copying biological molecules is a stickier proposition than making ordinary generic medicines because proteins are typically much larger and more complex than small molecule drugs. They are also often produced in cell cultures, and even small variations in how the cells are grown can change the properties of the protein produced."

Researchers, Biosecurity Board Debate How Open Virus Research Should Be 43

Posted by timothy
from the what-price-progress dept.
New submitter rackeer writes "Exchanging research results is at the heart of the scientific method. However, there are concerns about whether investigations of pandemics, which possibly constitute a threat to the whole population of earth, should be shared. The debate about research on the avian flu was discussed on Slashdot before. Now the main parties have their own two cents to say. On-line at the journal Science are commentaries both by authors of the paper in question, who went ahead with the publication, and by the national advisory board for biosecurity, which advised against publishing."

An anonymous reader writes "A skin cancer drug may rapidly reverse pathological, cognitive and memory deterioration associated with Alzheimer's disease, according to new research published on Thursday. Bexarotene, a drug that is currently used to combat T cell lymphoma, appeared to reverse plaque buildup and improve memory in the brains of mice with Alzheimer's disease by reducing levels of beta-amyloid plaques in the brain that cause mental deficits in Alzheimer's disease."

coondoggie writes "NASA is looking for technology that could offer green rocket fuel alternatives to the highly toxic fuel hydrazine used to fire up most rockets today. According to NASA: 'Hydrazine is an efficient and ubiquitous propellant that can be stored for long periods of time, but is also highly corrosive and toxic.' It is used extensively on commercial and defense department satellites as well as for NASA science and exploration missions."

The Himalayas and Nearby Peaks Have Lost No Ice In Past 10 Years, Study Shows 388

from the antifreeze-be-damned dept.
DesScorp writes "A story from UK's Guardian reports on a study of ice levels from the Himalayas area, and finds that no significant melting has occurred, despite earlier predictions of losses of up to 50 billion tons of ice. 'The very unexpected result was the negligible mass loss from high mountain Asia, which is not significantly different from zero,' said Professor Jonathan Bamber, who also warns that 8 years simply isn't enough time to draw conclusions. 'It is awfully dangerous to take an eight-year record and predict even the next eight years, let alone the next century,' he said." Readers have sent in a few other stories today relating to melting (or persisting) ice around the globe; read on for more.

from the now-where-was-I? dept.
An anonymous reader writes "A mild electrical shock to the brain before learning a new task may enhance memory, researchers reported on Wednesday. A team of neuroscientists demonstrated that electrical stimulation to a critical junction in the brain appeared to boost memory in a few patients with epilepsy, a surprising finding that have implications for Alzheimer's disease treatment."

Therapy Over IP Draws the Young, Isolated 93

Lucas123 writes "Psychiatrists say VoIP technology is more popular with patients than even in-person therapy when it comes to counseling — especially for their younger patients who are less intimidated by it. Along with many patients who like the convenience, telepsychiatry is a necessity for others who live in rural areas or are in, prisons, nursing homes or hospital ICUs. 'We've had just over 60,000 patient encounters. To my knowledge, only six have refused to be seen via teleconferencing,' said Dr. Avrim Fishkind, an emergency psychiatrist. 'We're tailor made for telemedicine because we don't check people's livers. We just talk.'" I wonder whether Eliza can be sued for practicing medicine without a license.

Three Unexpected Data Points Describe Elementary School Quality 340

Posted by timothy
from the real-estate-value-is-a-simpler-proxy dept.
garthsundem writes with a link to his story in Wired, according to which "Test scores and student/teacher ratio are nearly meaningless. But three new numbers do describe school quality: 1. (Test Scores/Parent Education): How do scores outpace expectations? 2. Test Score Growth: Any single score can be socioeconomics, but growth is due to the school. 3. (Teacher Salary*%Highly Qualified/Teacher Age): The best teachers will become highly qualified early, and will gravitate toward the best paying jobs." These factors seem to be at least interesting starting points; if you've shopped around for elementary schools, what else did you consider?

The Lack of Scientific Philanthropy In Japan 101

Posted by samzenpus
from the no-science-for-you dept.
ananyo writes "The University of Tokyo this week unveils the Japan's first institute named after a foreign donor: the Kavli Institute for the Physics and Mathematics of the Universe. The announcement adds Norwegian philanthropist Fred Kavli's name, along with a US$7.5-million endowment, to one of Japan's most successful institutes. The new center marks a turning point for Japan: to date, the country's universities and research institutes have long had to make do with few philanthropic donations. Strict laws governing university finances, and the lack of a philanthropic tradition, have discouraged the gifts that serve Western institutions so well. To get around the laws, instead of handing the endowment over to the institute, the Kavli Foundation will continue to manage the sum, giving the institute the return on the funds."

What Scorpions Have To Teach Aircraft Designers 126

Posted by samzenpus
from the taking-the-sting-out dept.
First time accepted submitter elloGov writes "The north African desert scorpion, Androctonus australis, is a hardy creature. Most animals that live in deserts dig burrows to protect themselves from the sand-laden wind. Not Androctonus; it usually toughs things out at the surface. Yet when the sand whips by at speeds that would strip paint away from steel, the scorpion is able to scurry off without apparent damage thanks to the unique structure of its carapace. Dr Han Zhiwu of Jilin University and colleagues have found that surface irregularities based on the scorpion's exoskeleton could substantially minimize atmospheric dust damage to aircraft."

The Science Fiction Effect 207

from the I-want-my-flying-car dept.
Harperdog writes "Laura Kahn has a lovely essay about the history of science fiction, and how science fiction can help explain concepts that are otherwise difficult for many...or perhaps, don't hold their interest. Interesting that Frankenstein is arguably the first time that science fiction appears. From Frankenstein to Jurassic Park, authors have been writing about 'mad scientists' messing around with life. Science fiction can be a powerful tool to influence society's views — one scientists should embrace."

If You're Fat, Broke, and Smoking, Blame Language 297

from the he-cannot-speak-it-good-like-we-do dept.
First time accepted submitter derekmead writes "A Yale researcher says that culture differences how much money we save, how well we take care of ourselves, and other behavior indicative of taking the long view, are all based on language. His study argues that the way a language's syntax refers to the future (PDF) affects how its speakers perceive the future. For example, English and Greek make strong distinctions between the present and the future, while German doesn't, while English and Greek speakers are statistically poorer and in worse health than Germans. (The study includes a broader swath of languages/nationalities, but that's a start.)"

Virtual Reality Helmet Designed For Deep Space Surgery 82

Posted by samzenpus
from the wearing-the-doctor-hat dept.
pigrabbitbear writes in with a link about a virtual reality helmet designed to help people deal with medical emergencies in space. "Humans are pretty fragile. A bad break in your hip can mean surgery and months of rehab. That's pretty bad, but what if you fall and break your hip on the Moon, or even Mars? You'd be hundreds of thousands or millions of miles from a fully stocked hospital and a surgeon with steady hands. There's the option of doctor-assisted surgery from Earth — a fellow astronaut performing the surgery with remote assistance from a doctor via video link. But the lengthy communications delay make this a poor option anywhere further than the Moon. Luckily for our Mars-bound descendants, the European Space Agency has a solution: an information-loaded assisted reality helmet that will let anyone identify and perform minor surgery to repair injuries."

New Technique Promises Much Faster Hard Drive Write Speeds 148

Posted by Unknown Lamer
from the sharks-in-my-drives dept.
MrSeb writes "Hold onto your hats: Scientists at the University of York, England have completely rewritten the rules of magnetic storage (abstract; full paper paywalled). Instead of switching a magnetic region using a magnetic field (like a hard drive head), the researchers have managed to switch a ferrimagnetic nanoisland using a 60-femtosecond laser. Storing magnetic data using lasers is up to 1,000 times faster than writing to a conventional hard drive (we're talking about gigabytes or terabytes per second) — and the ferrimagnetic nanoislands that store the data are capable of storage densities that are some 15 times greater than existing hard drive platters. Unfortunately the York scientists only detailed writing data with lasers; there's no word on how to read it."

Study: Online Dating Makes People "Picky" and "Unrealistic" 619

Posted by Unknown Lamer
from the i-really-love-computers-like-really-really-like dept.
New submitter garthsundem writes with this tale of digital love: "A newly published meta-analysis of over 400 studies of online dating (PDF) shows both its popularity (second only to meeting through friends) and its impact. More online daters report seeking a 'soulmate' online, and do so by searching through the wealth of available profiles. Unfortunately soul-searchers focus on faults, both in viewing profiles and then also once dating in person, leading to quick exits when relationships inevitably get complicated."
