Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

8.9K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

X-linked Traits01:19

X-linked Traits

58.3K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Light Acquisition02:16

Light Acquisition

9.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Sex-linked Disorders01:43

Sex-linked Disorders

108.5K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

86.3K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Water and Mineral Acquisition02:34

Water and Mineral Acquisition

35.4K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Summary

The "last link" for crime guns, meaning the time from acquisition to arrest, is a median of just two months. Most individuals acquired guns illegally, highlighting the need for stricter gun transaction enforcement.

Area of Science:

  • Criminology
  • Forensic Science
  • Public Health

Background:

  • Guns used in crimes are often old and have changed hands multiple times.
  • Existing research focuses on "time to crime" (retail sale to crime use).
  • Limited data exists on the "last link" duration (offender acquisition to crime).

Purpose of the Study:

  • To estimate the duration of the "last link" for crime guns.
  • To understand the acquisition methods of firearms by individuals involved in crime.

Main Methods:

  • Utilized data from the Chicago Inmate Survey (CIS).
  • Analyzed the time elapsed between gun acquisition and arrest for the current crime.

Main Results:

  • The median "last link" duration was found to be only two months.
  • 42% of respondents did not possess a gun six months prior to their arrest.
  • Most respondents were legally prohibited from purchasing firearms and obtained guns through illegal channels.

Conclusions:

  • The "last link" for crime guns is significantly short.
  • Illegal gun transactions are a primary source of firearms for individuals involved in crime.
  • Enhanced enforcement of gun transaction laws could rapidly impact gun use in crime.
