Frogs Communicate by Means of Ultrasonic Sounds

People are always fascinated by ways that some members of mammalian species (such as dolphins, bats and some rodents) communicate using sounds that we cannot hear. But think twice if you say the capacity of producing and detecting ultrasounds (frequencies greater than 20kHz) is limited to mammalians. A study implemented by Prof. SHEN Junxian from the CAS Institute of Biophysics (IBP) and colleagues in CAS and abroad showed that a rare frog species in China should also be added to that list. It is the first documented case of a non-mammalian species being able to use ultrasonic communication. Their work was reported in the March 16 issue of the journal Nature.     

Learn from Each Other in Friendship and Trust——An Interview with Prof.Herbert J(a)ckle, Vice President of MPG

BCAS:As Vice-President of MPG you got involved in the establishment of the CAS-MPG Partner Institute for Computational Biology (PICB) very early and have witnessed its growth from a small seed of an idea to a thriving centre for science excellence.As we know,PICB,a "joint venture" of the MPG and CAS,is administered via some procedures and mechanisms typical for an institute of the Max Planck Society.How would you describe or evaluate the implications of setting up and running an MPG-style institute in the Chinese context?     

Enterovirus B Sneaks into Victim Cells through Accomplice Receptors

<正>"If you know both the enemy and yourself well, you need not to fear for the results of a hundred battles," wrote Sun Tzu, a Chinese philosopher, in his famous the Art of War about 2,500 years ago. This is particularly true in the ever-lasting war against human viruses. Recently, a vital piece of information has been acquired concerning enteroviruses, which could cause many severe brain infections and even death in children. A recent study published in Cell unravels how these viruses sneak into cells with the help of accomplices from the host, opening a new window on developing drugs to specifically fight against them.     

Coordinating International Eforts to Address Global Environment Change--Report from the 35^（th） International Symposium on Remote Sensing of Environment

Ateam of Peking Opera warriors appeared on the stage in colorful costume and played drums accompanied by impassioned music in jazz-like, modern tempo - you might suspect that this was a scene from an opera theatre though the somewhat westernized music could be a bit confusing, but actually this was the herald of a brief ceremony to celebrate

Scientific communication,competition, and collaboration

<正>The late molecular biologist Gunther Stent once asked:‘If you were given all the sources you want to pursue your scientiic interest,but not allowed to talk to any other scientist,would you still do science?’he answer from many of us is probably no.Science is a community afair,and much of the joy in doing science comes from communicating with other scientists,who appreciate your work and contribute to it in various ways.Communication oten leads to collaboration that eventually results in scientiic accomplishment not atainable by working alone.Yet,intense competition in many areas has a negative impact on scientiic communication,and overemphasis by our institutions on     

Seeing through the Cosmic Ripples: Embrace the Era of Multi-messenger Astronomy

<正>Discovery of gravitational waves is not the end of the search, but the beginning of a new era.It has been almost four years since LIGO, the Laser Interferometer Gravitational-wave Observatory's first successful detection of a gravitational wave(GW) event – the merging of two black holes. This groundbreaking experiment eventually verified the existence of these space-time ripples as predicted by Albert Einstein. Nowadays, one can still hear and feel the rippling waves in the seemingly quiet cosmos – particularly in the astrophysical community. Apart from more GW sources,     

Odors Warps Visual Time Perception

正The brain is not a timepiece.Though it is equipped with senses like vision,audition,touch,smell,and taste,it has no direct access to or measure of the physical time(unless you read from a clock).Rather,it constructs the subjective"time"of an event from the dynamic multisensory inputs associated     

DEVELOPMENT OF A "DRY BOUNDARY LAYER"

As one of applications of the DRS model the author developed, introduced in this paper is a model calculation of the advance of the planctary boundary laycr (PBL) before clouds form. First derived are quasi analytical formulations for the PLB developmcnt, which arc vcrificd by the latcr integration of the modcl. Then, in comparisons bcwecn with and without radiation, modcl results indicate that the sensible heat from. the sea is the main source of the PBL eddy, however, the radiative cooling not only prevents the cquilibrium air tcmpcraturc from approaching the surface temperature but also brings about a certain diurnal variation in the PLB thcrmal stucture.     

Crystallize in CAS-MPG Chemistry

<正>Supported by the CAS-MPG Doctoral Promotion Programme, FENG Xianjuan and FAN Jing, both Ph.D. students from the CAS Shanghai Institute of Ceramics, studied for some years at the Max Planck Institute for Chemical Physics of Solids(MPI-CPfS) in Dresden. FENG, now a postdoctoral researcher at the MPI-CPfS, defended her thesis last September and received her Ph.D. Degree in last Jan; FAN just defended her thesis in April and will be granted with the Degree in the upcoming June. Let's hear in this interview(given in Feb 2014) what they would say about their study and life in Germany and envision how this experience will impact their future.     

Looking into the First Case of Software Bundle in China

On 13 December 2006,the Shanghai Higher People's Court rendered its final ruling in a case of dispute arising from infringement of copyright in computer software,holding that the plaintiff specially designed an output document for- mat for bundling its own developed application for use in the product it has made,and this act had gone beyond the scope of technological protection measures provided for in the Copyright Law,and that defendant's act of circumvent- ing the output data document format of said software was not an infringement.This is the first case of using technologi- cal protective measure for product bundle in China ever since the amended Copyright Law entered into force in 2001.The ruling is of far-reaching significance in guiding the courts to hear similar cases and for the orderly development of the related industry in China.

DESIGN OF INTERNETWORK MANAGEMENT BASED ON VLANs

Implement VLANs essentially creating smaller broadcast domains at layer 2, means that broadcasts sent out from a node in one VLAN won t be forwarded to ports configured to belong to a different VLAN. In this paper, we assigning users to VLAN groups on a switch, this help to gain the flexibility to add only the users you want into that broadcast domain regardless of their physical location. This setup can also work to block broadcast storms caused by a faulty network interface card （NIC） as well as prevent an intermediate device from propagating broadcast storms throughout the entire internetwork.

What Happens if Air Pressure Changes?

Air pressure is the force exerted on you by the weightof tiny particles of air (air molecules). Although airmolecules are invisible, they still have weight and take upspace. Since there's a lot of "empty" space between airmolecules, air can be compressed to fit in a smallervolume.
