Scientists have recently found that cognitive therapy can change the brain volume of people suffering from social anxiety disorder (SAD).
Iron is vital to bodily function, playing an important part in oxygen transport and metabolism. However, nutritional deficiencies or excessive bleeding can cause iron deficiency anemia in patients. Those who are anemic may feel tired or lethargic. Currently, millions of people who have iron deficiencies take iron tablets to supplement their iron intake.
A recent catalog of rare Earth minerals revealed that the total quantities of some of these minerals have a smaller volume than a sugar cube. However of the over 2,500 minerals in the catalog, many hold information that is crucial to understanding how the Earth formed. Robert Hazen, a researcher at the Carnegie Institution for Science, argues that while many people dismiss these rare minerals because they are so minimal in quantity, these minerals tell us how the Earth differs from the Moon, Mars and other planetary bodies. These uncommon minerals found only on our planet hold the key to knowing what makes Earth so special.
During Intersession, 25 students spent six days in Honduras sorting medications, shadowing doctors, seeing patients and running a temporary clinic for nearby citizens. The medical care they provided motivated citizens from all over the area to travel to the temporary clinic. Some citizens were rumored to have walked for over two hours to receive the medical care that Hopkins students were helping to deliver.
A recent study from the University of Cambridge and the Francis Crick Institute in London has provided evidence that almost all of our genes may be influenced by the food we eat.
A breakthrough by researchers at the University of British Columbia could change the function of windows by expanding the range of features they could offer.
One way to think about adult neurogenesis is that it is simply a way to modify neural networks on a cellular network. By making new neurons, the brain can form new neural circuits or, alternatively, abolish pre-existing circuits. Based on this framework, the hippocampus could be doing some heavy computations that require neural circuitries to be continuously rewritten and edited in a dramatic way, therefore requiring adult neurogenesis. Indeed, as the center for the formation of new memories, the hippocampus may need adult neurogenesis as a form of plasticity to rapidly process learning.
Cancer is a notoriously difficult disease to understand.
Lead poisoning resulting from the man-made health disaster in Flint, Mich. continues to affect a community of about 99,000 people. While Michigan’s state officials have switched back the water supply source from the Flint River to the Detroit water system fed by Lake Huron, the aged pipes of many service lines, corroded by the polluted water from Flint River, are still leaching lead into the water. This has forced Flint residents to rely on donations of bottled water for clean drinking water.
The Johns Hopkins Hospital recently revealed that it is ready to perform kidney and liver transplants between HIV-positive donors and HIV-positive patients. The hospital, which received approval to conduct this procedure from the United Network for Organ Sharing, will be the first hospital in the U.S. to perform an HIV-positive kidney transplant and the first in the world to perform an HIV-positive liver transplant.
First discovered in Uganda in 1947 as a mosquito-borne virus that caused a brief, mild illness, the Zika virus’s notoriety has expanded significantly as it continues to live up to its recent designation by the World Health Organization as a global public health emergency.
Let’s say you’ve just been Tasered and arrested by a police officer. As you lay there, dazed and in shock, the officer handcuffs you and reads you your Miranda rights. He asks you if you understand them, and you likely nod or reply a shaky “yes.” You can now be interrogated, and your words can be used against you.
Cosmologists announced on Feb. 11 that they have detected ripples in space-time called gravitational waves. This confirms predictions made a century ago by Albert Einstein and provides an entirely new way to observe the universe.
During early development, the nervous system is built by stem cells. These stem cells migrate on tracks laid out by cells called radial glia. A striking feature of radial glia cells is their long processes that extend over long distances. While radial glia cells were classically thought to only play roles in neural migration, it was later discovered that they also act as neural stem cells that give rise to neurons during development.
On Nov. 30, the Conference of the Parties (COP), consisting of over 190 countries, met in Paris to reduce the effects of climate change. By Dec. 12, this meeting had resulted in an agreement to hold the increase in global average temperature to two degrees Celsius above pre-industrial levels. For the United States, this involved a pledge to reduce greenhouse gas emissions by 28 percent below 2005 levels.
Geochemists from the University of California, Los Angeles (UCLA) have reported that the moon was formed by a colossal collision between the Earth and a “planetary embryo” called Theia roughly 100 million years after the Earth formed. While scientists were aware of this collision for quite some time, many thought that the Earth and Theia collided at an angle of 45 degrees or more. However, new evidence suggests that the impact was more likely entirely head-on.
The expression “we are not alone” is truly an understatement when considering the number of microbes that live in and on the human body.
Gold, the precious metal that built and destroyed empires, was the focus of millions of investors for years. Two years ago, gold prices peaked at around $2,000 per ounce. This ongoing interest in gold not only motivated ancient kings to start wars of conquest but also inspired a team of scientists to search for innovative methods of extracting gold.
While the power, efficiency and functionality of smart phones have grown rapidly in recent years, so has their size. Apple in particular has been releasing larger and larger mobile devices. This March, it is rumored that Apple will reveal its newest iPhone model. The new phone will purportedly be called the iPhone 5se, with “se” denoting “special edition,” and it will not be larger than four inches.
