(American Chemical Society) Your body is a delicately balanced chemical system, and if you take too much of a drug you destroy that balance. That's what happens when you overdose. This week on Reactions, learn how to spo...

(Lancaster University) A call for a change in the law to class men, forced to have sex with women, as rape victims has been made in a new study by Lancaster University researchers published today.Men have added their voi...

New research could be key to our understanding of how the aging process works. The findings potentially pave the way for better cancer treatments and revolutionary new drugs that could vastly improve human health in the ...

Human artificial chromosomes (HACs) could be useful tools for both understanding how mammalian chromosomes function and creating synthetic biological systems, but for the last 20 years, they have been limited by an ineff...

A surprising new discovery in mouse models reveals a previously unknown role for pain in immunity and has implications for treating autoimmune diseases.

HIV-infected cells release vesicles that contain a viral protein called Nef, impairing cholesterol metabolism and triggering inflammation in uninfected bystander cells, according to a new study.

In a new study, researchers slowed mutant fruit flies' metabolic rates by 50%, and the expected detrimental effects of many mutations never manifested. After experimentally testing fruit flies' many different genetic mut...

The US Centers for Disease Control and Prevention (CDC) recently developed an Autocidal Gravid Ovitrap (AGP trap) that attracts and captures female mosquitoes looking for a site to lay eggs. Now, researchers report that ...

Aging diminishes the ability of the eyes ability to focus up close. Research found that monovision, which uses lenses with different power in each eye, can cause dramatic misperceptions of distance and 3D direction for m...

Scientists have now discovered a key feature of embryonic tissue that helps explain how this process is carried out so faithfully each time. In a study of fruit flies, they found that the reproducibility of tissue foldin...

A specific class of bacteria from the gut prevents mice from becoming obese, suggesting these same microbes may similarly control weight in people, a new study reports. The beneficial bacteria, called Clostridia, are par...

Starting 6-month-old infants on solid food in the amounts recommended by standard feeding guides may lead to overfeeding, according to a new study.

A new biomimetic culture system mimics the environment of a living organ through continuous electrical stimulation and oxygenation, maintaining viability and functionality of heart slices for six days. Previous culture s...

The neurotransmitter brain-derived neurotrophic factor (BDNF) acts in the muscle, so that during strength training endurance muscle fiber number is decreased. Researchers have more closely investigated this factor, from ...

A new study uses a genetic screen to identify genes that protect cells from Zika viral infection. The research may one day lead to the development of a treatment for Zika and other infections.

Motility is an essential property of many cell types, and is driven by molecular motors. Researchers have now discovered that the motor protein myosin VI contributes directly to the deformation of the cell membrane, as r...

After nerve injury, the protein complex mTORC1 takes over an important function in skeletal muscle to maintain the neuromuscular junction, the synapse between the nerve and muscle fiber. Researchers have now shown that t...

The 3D analysis of crystal structures requires a full 3D view of the crystals. Crystals as small as powder, with edges less than one micrometer, can only be analysed with electron radiation. With electron crystallography...

Findings offer new insight into the complex world of motivation and reward by discovering the science behind giving up. The study is among the first to describe the effects of the complex nociception modulatory system. T...

A first-of-its-kind artificial protein -- designed on a computer and synthesized in the lab -- can be used to build brand-new biological circuits inside living cells. These circuits transform ordinary cells into smart ce...

Resources are limited on an airplane during an in-flight emergency and access to care is not always immediate. A new study reveals that 15.5 percent of in-flight emergencies involve children and that one in six cases req...

A new benchmarking study has determined the best analysis tools for identifying errors in a patient's DNA that are responsible for driving disease. Being able to pinpoint these 'genomic rearrangements' is vital for under...
