Computer models help decode cells that sense light without seeing

Researchers have found that the melanopsin pigment in the eye is potentially more sensitive to light than its more famous counterpart, rhodopsin, the pigment that allows for night vision.
For more than two years, the staff of the Laboratory for Computational Photochemistry and Photobiology (LCPP) at Ohio's Bowling Green State University (BGSU),
have been investigating melanopsin, a retina pigment capable of sensing light changes in the environment, informing the nervous system and synchronizing it with the day/night rhythm. Most of the study's complex computations were carried out on powerful supercomputer clusters at the

New application of physics tools used in biology

Alawrence suffragist National Laboratory scientist and his colleagues have found a replacement application for the tools and arithmetic usually utilized in physics to assist solve issues in biology.

Specifically, the team used physics associate degreed mathematical modeling to shed light-weight on one thing referred to as epigenetic memory -- however an organism will produce a biological memory of some variable condition, like quality of nutrition or temperature.

"The work highlights the knowledge domain nature of contemporary biology, particularly,
how the tools and models from arithmetic and physics will facilitate clarify issues in biology," aforesaid Ken Kim, a LLNL scientist and one in every of the authors of a paper showing within the February. seven issue of Physical Review Letters.
Not all characteristics of living organisms will be explained by their genes alone. Epigenetic processes react with nice sensitivity to genes' immediate organic chemistry surroundings -- and any, they pass those reactions on to future generation.
The team's work on the dynamics of simple {protein} protein modification is central to epigenetics. Like genetic changes, epigenetic changes area unit preserved once a cell divides. simple protein proteins were once thought to be static, structural elements in chromosomes, however recent studies have shown that histones play a vital changing role within the machinery accountable for epigenetic regulation.
When histones endure chemical alterations (histone modification) as a results of some external stimulant, they trigger short biological memory of that stimulant inside a cell, which might be passed all the way down to its girl cells. This memory can also be reversed once a number of organic process cycles.
Epigenetic modifications area unit essential within the development and performance of cells, however conjointly play a key role in cancer, per Jianhua Xing, a former LLNL postdoc and current academic at Virginia technical school. "For example, changes within the epigenome will cause the activation or deactivation of signal pathways that may cause growth formation," Xing other.

The molecular mechanism underlying epigenetic memory involves complicated interactions between histones, DNA and enzymes, that manufacture modification patterns that area unit recognized by the cell. to realize insight into such complicated systems, the team made a mathematical model that captures the essential options of the histone-induced epigenetic memory. The model highlights the "engineering" challenge a cell should perpetually face throughout molecular recognition. it's analogous to restoring an image with missing elements. The molecular properties of a species are evolutionarily chosen to permit them to "reason" what the missing elements area unit supported incomplete data

How to Compliment Girls Part 3 (Complimenting Don’ts)

Avoid complimenting certain physical features. The thing is, if you build up a girl’s feeling of worth in a particular feature, in most cases that feature is going to go away over time and she’ll end up feeling worthless because it’s gone. So avoid complimenting butt, legs, etc. Eyes and hands are a safer bet.

Complimenting on physical features works even better if you tie the compliment to her personality or actions. For example, tell her that her eyes are beautiful and that you love how her determination shines through her eyes when she’s working so hard.

Don’t sexually compliment girls you don’t know well. This is the biggest no-no when it comes to complimenting girls. You will obviously see girls you don’t know that you’re very attracted to, and you may think that paying them a compliment is just a nice thing to do, but if you don’t know the girl then a sexualized comment is just going to make you look like a creeper

How to Compliment Girls part 2 (Complimenting Dos)

Be sincere. Any compliment you say, you have to absolutely mean. Girls will always be able to tell if you don’t mean it. They may not call you on it, but they’ll know and it will make them feel awful and awkward.

Be respectful. This is the main key to being able to Compliment girls without offending or upsetting them. If you respect them as people, as valuable human beings with worthwhile opinions, feelings, hopes and dreams, who are capable of doing everything that you can do, then any compliment that comes out of your mouth will probably be fine.

Think about how the Compliment would make you feel. If you’re still worried, think about how the compliment would make you feel. Don’t just look at the surface of the compliment...think about the things that she worries about and the experiences she’s had. Think abou

How to Compliment Girls Part 1 (Finding Things to Compliment)

Evaluate what the girl values in herself. The first thing you’ll want to do is think about the girl and what you know she values in herself. Girls are conditioned to shy away from compliments and she’ll be much more open to accepting a compliment she agrees with. Notice what she’s proud of, from your experiences with her and compliment her on those things.

For example, if she’s clearly very eager to share something she’s done with other people, that’s something you could compliment her on.

Consider what she struggles with or works on. Like yourself or anyone else, she probably likes to have her hard work validated. If you know she’s worked very hard on something or that there’s something she feels inadequate or self-conscious about, you

Engineers Create Light-Activated 'Curtains'

 A research team led by Ali Javey, associate professor of electrical engineering and computer sciences, layered carbon nanotubes -- atom-thick rolls of carbon -- onto a plastic polycarbonate membrane to create a material that moves quickly in response to light. Within fractions of a second, the nanotubes absorb light, convert it into heat and transfer the heat to the polycarbonate membrane's surface. The plastic expands in response to the heat, while the nanotube layer does not, causing the two-layered material to bend.
"The advantages of this new class of photo-reactive actuator is that it is very easy to make, and it is very sensitive to low-intensity light," said Javey, who is also a faculty scientist at the Lawrence Berkeley National Lab. "The light from a flashlight is enough to generate a response."

Supreme Court rules cops can collect your DNA if they arrest you

Your constitutional right to not be searched or detained by law enforcement officials without reasonable suspicion or probable cause has been further eroded by a recent Supreme Court ruling, which now allows police officers to freely collect DNA samples from
individuals they arrest in connection with serious crimes. Even if such individuals are eventually found to be innocent and are later acquitted, such DNA collection can legally take place prior to this determination, according to the ruling's ambiguity.

Scientists discover secret code hidden within human DNA

Scientists have discovered a secret second code hiding within DNA which instructs cells on how genes are controlled. The amazing discovery is expected to open new doors to the diagnosis and treatment of diseases, according to a new study.

Ever since the genetic code was deciphered over 40 years ago, scientists have believed that it only described how proteins are made. However, the revelation made
by the research team led by John Stamatoyannopoulos of the University of Washington indicates that genomes use the genetic code to write two separate languages.

Egypt: Sarcophagus Leads to the Tomb of a Previously Unknown Pharaoh, from 3,600 Years Ago

The discovery of pharaoh Senebkay's tomb is the culmination of work that began during the summer of 2013 when the Penn Museum team, led by Dr. Josef Wegner, Egyptian Section Associate Curator of the Penn Museum, discovered a huge 60-ton royal sarcophagus chamber at South Abydos. The sarcophagus chamber, of red quartzite quarried and transported to Abydos from Gebel Ahmar (near modern Cairo), could be dated to the late Middle Kingdom, but its owner remained unidentified. Mysteriously, the sarcophagus had been extracted from its original tomb and reused in a later tomb -- but the original royal owner remained unknown when the summer season ended.

In the last few weeks of excavations, fascinating details of a series of kings' tombs and a lost dynasty at Abydos have emerged. Archaeologists now know that the giant quartzite sarcophagus chamber derives from a royal tomb built originally for a pharaoh

Caffeine stirs our memory

A jolt of caffeine can boost memory, according to a recent study that provides a scientific motive for students slurping coffee, tea or energy drinks when cramming for exams.

A team at Johns Hopkins University in Baltimore, Maryland, found that caffeine enhances certain memories for at least a day after they were formed.

Evidence for caffeine as a memory booster has been anecdotal until now.

This is because the process of registering memories - say, reading a book ahead of an exam - may happen in conditions where the person is eager to absorb and retain information.

Breast screening over 70 'helps early detection'

Breast screening of women aged 70 to 74 provides a notable benefit in terms of early detection, according to the authors of a new Australian study.

The finding supports recent moves by some juristications in Australia and overseas to extend screening programs to women older than 70 years.

"The findings are suggesting that it's useful for women who have been participating in screening aged 50 to 69 to continue participating in screening because screening does seem to lead to earlier detection of cancers," says first author Dr Carolyn Nickson, an epidemiologist from the University of Melbourne.

Traditionally, breast screening has been encouraged for

Massive Galaxy Cluster Verifies Predictions of Cosmological Theory: First Detection of Kinetic SZ Effect in an Individual Galaxy Cluster

MACS J0717.5+3745 is an extraordinarily dynamic galaxy cluster with a total mass greater than 1015 (a million billion) times the mass of the sun or more than 1,000 times the mass of our own galaxy. It appears to contain three relatively stationary subclusters (A, C, and D) and one subcluster (B) that is being drawn into the larger galaxy cluster, moving at a speed of 3,000 kilometers per second.
The galaxy cluster was observed by a team led by Sunil Golwala, professor of physics

Ancient DNA sparks new mystery

it.” DNA from a 400,000-year-old leg bone is breaking records. It also raises questions about how closely ancient humanlike creatures were related to each other. The genetic material is four times older than any other recovered from a pre-human ancestor, or hominid. And scientists say the DNA links this individual, recovered from Spain, with a much later humanlike group called Denisovans. Their remains have been found only in East Asia’s Siberia.

The newly studied leg bone turned up nearly a decade ago. Scientists retrieved it from among

Physical Reason for Chromosome's Cylindrical Shape Discovered

This work gives a solution to a fundamental question in structural biology: Why do metaphase chromosomes have their characteristic elongated cylindrical shape? The proposed solution is consistent with the structure of metaphase chromatin and with the nanomechanical properties of chromatin and chromosomes. It is a research at the interface between biology (higher order chromatin structure) and physical sciences (supramolecular structures and nanomaterials). This approach goes beyond the capabilities of current structural biology based on X-ray crystallography, because it allows the study of an enormous supramolecular assembly that cannot be crystallized. The work has been published in the Journal of the Royal Society Interface.
In the cell nucleus, genomic DNA molecules are associated with histone proteins and form long chromatin filaments containing many nucleosomes. Previous microscopy
